Structure and Management The Australian Research Council Nanotechnology Network is managed by a Management Committee which met 5 times during the 2006 year. The first Board meeting for 2006 was held at the Department of Physics at Macquarie University on the 22nd of February 2006. Other meetings held during 2006 were in May at Melbourne Airport, in July during the ICONN2006 Conference in Brisbane, in September at the Ian Wark Institute at the University of South Australia and at the University of Western Australia in December. This management board represents the wider membership and is chaired by an independent chair. The committee determines the priorities for each activity and allocates the budget for the network. A Network Manager manages the day to day administrative tasks under the Guidance of the Network Convenor.
Management Committee Chair The duties of the Chair are to chair Management committee meetings, provide advice to the Network, confirm meeting minutes for circulation to Management committee members, represent the network at important meetings and provide general guidance to the network management.
Convenor The convenor has overall responsibility for the Network operations and for meeting ARC requirements and guidelines. Represent the network at key Nanotechnology meetings in Australia and key International network meetings. Supervise Network staff and provide overall direction to the network activities.
Management Committee Members The management committee members participate in committee meetings. They serve on the Working Group sub committees, represent the Network and publicise network activities, organise and actively participate in the management of network activities, act as ambassadors for the Network and provide advice to the network members about network programs.
Working Groups Committee members form into working groups that assess funding applications and other issues prior to the matter going to the full Management committee for voting.
There are four working groups and their areas comprise Events Working Group – evaluates all applications for sponsorship funding for Conferences, Workshops, Summer and Winter Schools and Short Courses. Visits Working Group – evaluates all applications for Short and Long Term Visits and Overseas Travel Fellowships. Outreach Working Group – evaluates outreach proposals such as Public Lectures, Distinguished Lecturers visits, outreach and Webpage. Education Working Group – evaluates applications for student, ECR and Entrepreneur Forums and educational activities.
5 The Convenor fills in if a working group member is unavailable or is one of the applicants (when there is a conflict of interest).
The Management Committee (MC) comprises of the following members, representing 6 States, students and early career researchers and chaired by an Independent chair. The MC has representatives from ANSTO, CSIRO, DSTO and industry.

International Conference on Nanoscience and Nanotechnology 2006 The Following is an adapted copy of an article written by Prof Fletcher, Chairman of the ARCNN, for “Materials Australia “39-(5), 10-11(2006) Nanotechnology in its various forms is a rapidly growing field around the world, and Australia has had several National Conferences on various aspects of the subject over the past few years. With its first International Conference on Nanoscience and Nanotechnology, ICONN 2006, held in Brisbane over the week July 3–6, the local scene has become international. The conference was co-chaired by C. Jagadish (ANU) and Max Lu (UQ). The conference was organised by the Australian Research Council Nanotechnology Network, which was established in 2004 with funding from the Australian Research Council to promote collaboration between Australian researchers in the field and to provide links to the international scene. The Network now has more than 620 members, and the high level of interest in the subject is shown by the fact that the Conference attracted 442 participants from 21 countries, presenting a total of more than 200 oral papers and 100 posters. The two poster sessions were lively and 6 poster prizes were awarded. During the conference dinner, in addition to poster prizes, overseas travel fellowship awards were presented to 4 winners.
Delegates attending a plenary session Prof Jagadish addressing the delegates Brisbane in July was an excellent place and time to hold the Conference and the weather was delightful, allowing pleasant lunch-time strolls along the river parklands near the Convention Centre where it was held. The conference program included 8 plenary talks with distinguished overseas invited speakers and then was divided into 4 to 5 parallel sessions with 10 symposia covering everything from quantum computing through nano-photonics to nano-medicine. Panel discussions on topics covering safety, standards, ethics, social and environmental issues, patenting, commercialization, education, skills, etc were very well attended with lively discussion.
A list of Plenary and Invited speakers and their talk titles are given in appendix A
11 Prof Chunli Bai – Plenary Speaker Prof Fletcher presenting award to Kris Kilian The whole conference was preceded by a day on which four free short courses, aimed particularly at students and early-career researchers, were conducted in parallel pairs. The subjects covered were bio-nanotechnology, nano-electronics, nano-fabrication and nano- characterisation. These proved to be very popular and each attracted 100 to 160 participants. It is difficult to summarise the content of a large conference covering so many different aspects of a large subject. The impression gained, however, is that nanoscience and nanotechnology now pervade and even underpin much current scientific research and technological development in a very wide range of fields. Part of this is simply a different way of looking at things and a focus on detail that is perhaps 10 times smaller than we have been accustomed to consider, but this tends to unify approaches in what were previously considered to be almost unrelated fields. At this level, biologists can talk to physicists and both can understand the nature of the problems that are being faced. By working together there is better chance of finding solutions to old problems or of discovering exciting new possibilities. Because the aim of the Nanotechnology Network is to promote collaborations among Australian researchers in the field, and particularly to encourage early-career researchers and graduate students, free registration was provided for those Australian ECRs and students presenting papers. This proved to be a very popular move and the conference attracted 138 PhD students and 69 other ECRs. In addition to funding from the Nanotechnology Network, the Conference was supported by the Australian Government Department of Industry, Tourism and Resources, by the Australian solar-cell company Dyesol, the Australian Institute of Bioengineering and Nanotechnology (University of Queensland), and Watermark patent attorneys. Several Australian scientific and engineering societies were technical co-sponsors. These were the Institute of Electrical and Electronics Engineers, Electronic Devices Society, Lasers and Electro-Optics Society, IEEE Nanotechnology Council, Australian Institute of Physics, Materials Australia, Australian Research Network for Advanced Materials, and the Nano Research Society. In all there were 16 exhibition booths maintained during the conference.
12 A detailed listing of the topics covered by the conference symposia, together with reproductions of the six prize-winning posters and a photograph of the conference participants on the steps of the Convention Centre can be seen on the website www.ausnano.net which also gives more information about the Network and its membership. The next conference in the series, ICONN2008 will be held in two years time in Melbourne on the 25-29th of February at the Melbourne Exhibition and Convention Centre. We all look forward to making it even more exciting and successful than ICONN 2006 has been. ICONN 2008 will feature an industry stream examining industrial developments in the field. .

ICONN 2006 Delegates ICONN Facilitated the interaction between Industry and Early Career researchers which has led to increased employment opportunities which otherwise would have been very difficult. Thanks to this interaction one such researcher who attended the conference is now employed with one of the industry organizations who participated at the conference.

General Comments • Disadvantage of this conference too much wine less quality food • Try to make it more international by having a larger percentage of non-Australians. Currently ICONN 06 is more of a showcase of Australian Science with some guest speakers from outside. Given travel costs to Australia the conference registration is rather expensive. • Top shelf Conference • Fabulous Location fabulous people fabulous time fabulous science.Good Conference, well organised and run. Thoroughly pleased only comment I was hoping plenary speakers would give a more broad explanation for their field often too specific/In depth.
21 • Speakers were fantastic – food was fantastic • Advertise better outside Australia put non Australian talks not on the last day – introduction will be facilitated if talk is earlier for the “ minority” • All PhD students should be able to give an oral presentation • Could have had a stall from travel agent for local travel • Student concession discounts • More Workshops, more stalls science based/industry/corporate • Less NOISE, more industry focused workshops/presentations, where were the nanotech companies • ARCNN sponsored the students which is excellent, but I think for non students registration is quite expensive • Short courses to be extended for another day. Sessions to be split up according to bread topic of application For example, Energy Concession, Photonics, Electronics, Materials Sciences More or less such as of now • The Conference was very well organised and the catering exceeded expectations. Well done and thank you. • Perfect Conference! Great! • Great Job and Conference Perth would be an exciting venue for the next ICONN08 Cheers • The wifi system is not stable. I have some difficulties connecting to the server. • It would be great if the feedback on posters is provided to the delegates • More International Good quality presentations are expected. • The names of sections may be more specific! • Plenary Speakers: at least 2 of the talks were very similar to what was presented at the short courses which was perhaps overkill. Also surely we would have some Australian talent that could be used. • No particular comments all seems to be well organised • Short courses are a good idea, well organised. • Some of the invited lecturers clash with other invited lecturers that are on similar topics, so you have to miss a lecture that interests you-timetable good but not perfect. • For morning and afternoon tea, just one type of cake and a fruit platter instead of 5 types of cake. • Move political talk to special session-NOT in plenary session • Larger trade contribution • The student forum was very helpful and insightful, and definitely should be repeated in ICONN08. • Disappointed that ICONN didn’t attract many research companies other businesses, despite Symp K. Would like to see discussion sessions that explore cross-disciplinary collaboration between the different symposium streams. • Re attractiveness of Symp K, which is a non science stream that is one of four parallel steams- the other streams being sciences and is in smallest room P3.Therefore will Symp K attract significant interest amongst ICONN registrants? Will that interest increase over next two years and be reflected in a greater focus in ICONN08 – Matt Gredley –DITR MEGA Sponsor. • Providing WLAN was a very good idea- very good organisation- Excellent support for students.
22 • Really appreciated the student forum-thought it was a very valuable time and should definitely be repeated in future conferences!! Conference in general was very professional. • Have another student symposium as this was a fantastic opportunity to hear views from like-minded students from around Australia. • Food variable in quality, conference bag and inclusions relay cheapskate. Staff polite but always focused on their own work so they would kick us out of poster session or kick us off using high table for laptop just so they could get on with their food prep. Wireless good, Presentations great, should be more prizes. Need more lively music and a dance floor….. • We traveled from U.K – It was worth it! • The conference has been above world class standards- most impressive, particularly catering, technical support for speakers etc. Only suggestion would be smaller handbook (A5) for convenience. Organisation was magnificent including email notifications, confirmations. Very calm!, no dramas, plenty of help and support Well done and thank you • Bigger prize for poster session (say $1000) would get a more appreciable performance by students!! You must excite students more (with money). • 15 minute plenary speech for student winner of 2006? • The great thing about the band music at the dinner was the great relief when they stopped playing and went away! • It was very expensive. I would like to see the price come down ( although I am ECR I was not presenting – full fee) • Increase the time for each oral presentation, 15 minutes is definitely far less than enough. • Maybe a session where students can meet plenaries in small groups. • More sessions on development and commercialisation would help to focus researchers more on commercial outcomes and long term viability. • Free registration for students and ECRs is a very good idea. Excellent range of plenary and invited talks. Student talks well represented. • Have forum to engage industry with research institutes – even as simple as identifying specific aspects of interest on registration. • Thank you for well organising the conference. Thank you for the special diets, special meals. It would be better to provide the special ingredients of the refreshments provided for morning and afternoon tea. • Congratulations! Proceedings outstanding Venue magnificent • More student awards (best presentation etc) • Very well organised and excellent line up of invited speakers- Thank you • Experiences some difficulties with talks in similar top areas clashing at the same time in different symposia. Some what unhappy with magnitude of registration fee. • Coffee should be provided throughout the conference after refreshments also Food selection poor. • Excellent post grad ECR attendance, fantastic opportunity for post grad and ECRs – young content provided terrific atmosphere. • Change the plenary speech from morning to afternoon or some other times so that everyone can attend • Compliments to the great conference ambassadors • Targeted one day workshops with a focus (narrow) might be worth trying especially if a renowned international visitor can be involved. The focus would in any research area or more broadly other issues like media presence, ethics, political influence etc. 23
NOVA TOPIC ON NANOTECHNOLOGY The ARCNN Management Committee voted on sponsoring a NOVA Nanotechnology topic on the Academy of Science website www.science.org.au/nova . This topic went online in March 2006.
See Appendix B – Nanotechnology – taking it to the people
NANOTECHNOLOGY FACT SHEETS ARCNN has engaged a Science writer to develop a series of fact sheets in the form of flyers on nanotechnology with the help of the management committee for the general public and members. The first fact sheet has been a popular one with the Young Nanoscience Ambassador Program awardees. They distributed these flyers in the schools that were visited. These articles will be a regular feature on the website.
See Appendix C for a copy of the first article in the series titled ‘Building Carbon Nanotubes’
ARCNN NANOFORUM The ARCNN NanoForum was launched in December 2006 and it is still in its initial stages. We expect that this site will be a focal point for students and researchers alike to interact and discuss all topics in the nanotechnology field.
See Appendix D – ARCNN Nanoforum on the website
NANOTECHNOLOGY FACILITIES AND CAPABILITIES REGISTER In the last few months of 2006 ARCNN developed a Nanotechnology Facilities and Capabilities Register which is connected to the ARCNN website. The aim of this register is for members to be able to look for specific nanotechnology facilities and expertise that are available across Australia.
See Appendix E – An example of a facility that is on this register.
24 DISTINGUISHED LECTURER TOURS The aim of the Distinguished Lecturer Program is to bring international experts in the field to Australia and to give lectures in various institutions across the country. This also allows young scientists to interact with internationally renowned scientists in the field and allow Australian researchers to be aware of state of the art research overseas. These visitors will act as Ambassadors for Australian Science internationally. There were five Overseas Distinguished Lecturers invited to tour Australia and talk about their fields of research and expertise. CD Video recordings of these seminars have been distributed to members free of charge based on requests received. These CD’s are very popular and we are still receiving requests for free CD’s of Distinguished Lecturer seminars presented in 2005. Copies of 2006 Distinguished Lecturer seminars and special lecture CD’s are attached.
Professor Richard Kaner Professor Richard Kaner is from the University of California, Los Angeles (UCLA). His current research focuses on novel synthetic routes to new materials including nanowires and nanofibres During his February visit to Australia, Professor Kaner gave a lecture on the topic Processable Polyaniline Nanofibres for Flash Welding, Sensors and Actuators at the following institutions: University of New South Wales, Sydney Macquarie University, Sydney The Australian National University, Canberra Monash University, Melbourne University of Tasmania, Hobart University of Queensland, Brisbane
Emeritus Prof Neville Fletcher, Prof Kaner and Prof Jagadish
Abstract By modifying the conventional chemical oxidation polymerization of aniline, we have developed two simple approaches to synthesize polyaniline nanofibres with diameters tunable from 30 to 120 nm. The key to producing pure nanofibres is to suppress secondary growth that results in agglomerated particles. Both interfacial polymerization and rapidly mixing aniline, oxidant and acid produce pure nanofibres. These processes are template-free and readily scalable. Stable and processable colloids are now available. Polyaniline nanofibres exhibit an exceptional photothermal effect in which they instantaneously melt and cross-link upon exposure to a camera flash. This novel flash welding technique can be used to form patterned nanofibre films, create polymer based nanocomposites and make asymmetric polymer membranes. These asymmetric structures can act as mechanical actuators (artificial muscles) when exposed to strong acids. Polyaniline nanofibres are useful in many applications such as resistive-type sensors where their high surface area enable very rapid response times often less than two seconds. Polyaniline nanofibres can be modified to respond to many different vapors including toxic agents such as hydrogen sulfide. The key is using a metal salt such as CuCl2 which reacts with H2S to produce CuS and HCl. This process converts a weak acid (H2S) into a strong acid (HCl), which in turn can be readily detected at very low concentrations.

Abstract
Interaction Effects in Electron Transport in One-Dimensional Quantum Wires By means of varying the electrostatic confinement from patterned gates, electron transport in two dimensions can be converted into one, in particular the use of GaAs heterostructures has shown striking results due to the relative absence of electron scattering. Electron transport in one- dimensional ballistic quantum wires has been, by and large, described using the Landauer formula where the conductance is expressed in terms of transmission and reflection probabilities of electron waves. The overall conductance is given by T(2e2/h)n, where T is the transmission coefficient and n is the number of one-dimensional subbands occupied which can be changed by varying the confinement potential. This behaviour has been observed in very great detail and in the ballistic regime it is possible to observe wide plateaux of quantised resistance. A description beyond this non-interacting picture has now become necessary to understand some of the recent experimental observations. These include the 0.7 structure, a conductance structure at 0.7(2e2/h) in zero magnetic field, 0.7 analogue, very similar to the 0.7 structure in a high magnetic field when there is crossing of two spin levels and plateaux at 0.5 (2e2/h) observed occasionally and to which the 0.7 tends with decreasing carrier concentration. Detailed studies of the 0.7 structure suggest spontaneous lifting of the spin degeneracy as a cause, which is supported by a number of theoretical studies. Further evidence also comes from studies of thermopower, shot noise, and magnetic focusing. We will review some of these results, and present recent work on quantum wires fabricated by different techniques. 26 Professor Henry Smith

Abstract Living systems provide living proof of the importance of nanostructures, since all of their functions originate from nanoscale molecular assemblies (e.g., mitochondria, motor proteins, etc.). A living system, whether a bacterium or a human being, can be considered .information embodied in macromolecular assemblies.. The current interest in nanoscale science and engineering is aimed ultimately at achieving high functionality from molecular and nanoparticle assemblies. Such high functionality will be achieved only if we are able to introduce deterministic structural complexity i.e., information, into such assemblies. By using lithographically patterned surfaces to guide the self assembly of block copolymers, and to control the location of dislocations, we have taken the first tiny steps in the direction of putting information into nanoscale assemblies. I’ll discuss current research in nanopatterning and templated self-assembly, and extensions to greater complexity and high functionality.

Abstract
Super magnetic particles for diagnostic and therapeutic purposes. Nanoparticles for biomedical applications such as target drug delivery, non-viral vectors for gene delivery, contrast agent for in vivo imaging (MRI) or in biosensors have to fulfil very different requirements simultaneously. From the biological point of view, the size plays also an important role regarding up take mechanism by cells or to control the colloidal behaviour in contact with blood. Recent results show that even more important are the nature of the biocompatible coating of the particles and properties like surface charge and zeta potential. In this presentation, methods for the synthesis of biocompatible particles with properties which fulfil the physical as well as the biological needs will be presented. The presentation will be focused on superparamagnetic particles for target drug delivery or for gene therapy. This type of nanoparticles systems, including an inorganic core and different organic molecules at the surface are difficult to synthesis, because the coatings of inorganic and/or organic nature are not always compatible regarding the colloidal stability. Additionally derivatisations with biological molecules, which are often larger then the core particle are needed. The colloidal stability of the suspension during fabrication and application is therefore one of the major challenges during synthesis of the particulate systems. In a second part a review of medical applications of such particles will be given. Especially the relationship between particle properties, including surface properties, and up-take capacity of these particles by cells will be discussed. Additionally to the particle properties, external magnetic field could have an interesting effect of transfection rate, drug targeting efficacy and the imaging process. Recent results regarding non-viral gene transfection using superparamagnetic particles and a dynamic magnetic field will be finally presented.

Abstract
Spin-Based Semiconductor Heterostructure Devices Semiconductor spintronics has been the subject of intensive experimental and theoretical investigations aimed at realizing devices which can outperform their charge-based counterparts, yet no commercial applications have been realized to date. To this end, we have studied the processes of spin injection, transport and detection of spin polarized carriers in compound semiconductor based devices consisting of magnetic – non-magnetic semiconductor heterostructures. Measurements on conventional spin-valves suffer from spurious contributions from anisotsopic magnetoresistance (AMR) and stray Hall voltages arising from the ferromagnetic contacts. We have studied the magnetoresistance of lateral spin-valves fabricated from an epitaxially grown MnAs/GaAs heterostructure and utilizing a Schottky tunnel barrier for efficient spin injection. A coercive field difference between the two ferromagnetic MnAs contacts is obtained by a difference in aspect ratio. Peak magnetoresistances of 3.6% at 10K and 1.1% at 125K are m channel length, which is indicative of diffusiveμmeasured for a 0.5 spin transport. The agnetoresistance increases with increasing bias and with decreasing temperature. Control experiments have been carried out with non-local spin valves and AMR devices to confirm the spin-valve effect. The spin-polarized vertical cavity surface-emitting laser (spin-VCSEL) promises a number of advantages over a conventional VCSEL – enhanced intensity and polarization stability as well as a reduced threshold current – and has potential applications in cryptographic communications and reconfigurable optical interconnects. We have recently reported the first electrically injected spin VCSEL and a reduction of threshold current in these devices through electrical injection of spin polarized electrons. An electroluminescence polarization of 23% and threshold current reduction of 11% are obtained in an electrically-pumped spin-polarized vertical-cavity surface- emitting laser. Electron spin injection is accomplished utilizing a regrown Fe/n+ Al0.1 Ga0.9 As Schottky tunnel barrier deposited around the base of the laser mesas. Negligible electroluminescence polarizations and threshold current reductions are measured for nonmagnetic and Fe-based control VCSELs, which provides convincing evidence of spin injection, transport, and detection in our spin-polarized laser. The properties of these spin-based devices will be described and discussed.

ABSTRACT BIOLOGY INSPIRED NANOMATERIALS The study of the synthesis, exotic properties, assembly/packaging and potential commercial application of nanomaterials is an extremely important topic of research that is expected to have far-reaching global impact. The focus of my talk will be on an emerging branch of nanotechnology that derives its inspiration from biology. Recognizing that some of the most exquisite and highly functional nanomaterials are grown by biological systems (examples include silica by diatoms and magnetic nanoparticles by magnetotactic bacteria, many researchers have focused attention on understanding how inorganic materials are made by biological systems and attempting to replicate such processes in the lab. In my laboratory, we have investigated the use of plant organisms such as fungi in the synthesis of nanomaterials over a range of chemical compositions that include metals, metal sulfides and oxides. An exciting development is the use of plant extracts in nanoparticle synthesis wherein large concentrations of gold nanotriangles have been obtained that have potential application in cancer hyperthermia. Organisms such as fungi are not normally exposed to metal precursor stresses – that they should be capable of a broad range of biochemical transformations to negate these stresses is useful in materials chemistry and throws up exciting possibilities. Recently, we have also shown that bacteria may be ‘trained’ to synthesize magnetite when challenged with suitable iron complexes under aerobic conditions]. 30
Special Lecture - Prof Ratnesh Lal 3/5/2006 Prof Ratnesh Lal is from the Neuroscience Research Institute at the University of California, Santa Barbara. His areas of research interest are neuroscience, nanoimaging and nanomechanics from single molecules to whole tissues.
Integrated nanoimaging systems and nanosensors for iointerfaces ”Biointerfaces, such as membrane and membrane macromolecules are nanoscale structures that define and govern complex biological systems and their physical and chemical properties. Simultaneous examination of nano-scale physical properties and functional activity and the underlying ultrastructural substrates is limited. Multi-dimensional scanning probe microscopy (MSPM) can map hysicochemical properties, including surface energy at atomic scale, interaction forces between single molecules, viscoelastic and thermal properties of complex biological specimens, and simultaneously image the underlying ultrastructure with nanometer resolution. Significantly, such studies can be performed on hydrated biological systems with on- line addition of physiological and pharmacological perturbations. We have used MSPM to examine physicochemical properties and direct structure-function correlation for a variety of biological systems ranging from nanometer to micrometer scale (e.g., purified biomacromolecules, cells, and tissues). Such multiscale structure-function studies have produced novel findings with direct relevance to sustenance of the biological systems. In this presentation we will discuss our results on two inter-related areas: i) how integrated muldimodal, multiscale and multidimensional AFM imaging of biological mcromoleclues (which includes ion channels and receptors) provides new understanding of the molecular mechanisms underlying biological systems. ii) How AFM imaging, nanomanipulation and nanopatterning, and NanoMEMS can be used for biotechnology applications (e.g., biosensors, biomimetics).”
31 Special Lecture - Prof Renugopalakrishnan 23/6/2006 Professor Renugopalakrishnan is from the Harvard Medical School, Boston, USA. His area of research is Bionanotechnology- Protein Based Memory Storage. He gave a talk on BIO MEMS at the Leonard Huxley Theatre at ANU on the 23rd of June.
Abstract: Protein-based biosensors combine the selectivity of proteins with the processing power of modern nanoelectronics and optoelectronics to offer new powerful analytical tools with major applications in technology and medical diagnostics. With the cytochrome family as a starting system, we have used two main approaches of protein engineering, rational design and combinatorial synthesis, to obtain efficient electron transfer systems for the fabrication of amperometric biosensor devices. Liposome encapsulation for immobilization would be used to make second generation biosensors, involving biomaterial mediators followed by third generation of directly coupled enzyme electrodes with no mediators on the surface of the material to facilitate cytochrome c based biosensors to improve signal/noise ratio and miniaturization. Our initial target analytes are nitric oxide and carbon monoxide, major contaminants in the atmosphere. The physical and nanostructural properties of immobilized cytochrome c and its mutants on the transducer surface have been investigated AFM) and cyclic voltammetry. These amperometric devices will be tested for their selectivity, sensitivity, accuracy, response time, recovery time and working lifetime. Our approach is unique in each step. The proprietary mutant design technology is to be used for the design of new proteins in terms of analyte specificity and amperometric redox potential. The nano scale arrangement of the biomaterial with a thin metal coating paves the way for high signal/noise ratio leading to mediatorless biosensors. A unique, cost-effective, integrated, high efficient, lab-on-a-chip device based on the technology of carbon nanotube is under development that will measure glucose, cholesterol, lipids from a single drop of blood on a single platform. When glucose oxidase, cholesterol oxidase, cholesterol esterase, lipase are coupled to carbon nanotubes (CNT), the full potential of proteins as sensors are realized to a much greater extent than protein-based biosensors. The nano-dimensions of single walled carbon nanotubes and their electronic properties make them an ideal substrate candidate for anchoring the proteins for biochemical sensing. Cholesterol composed of molecules of triglyceride, low-density lipoprotein, high- density lipoprotein, and glucose, is very important because of their crucial role in coronary heart disease and diabetes.

Abstract
Disruptive Abundance: Nanotechnology and Human Life Nanotechnology is the name given to a broad field of science and applications. At its most basic level— called molecular manufacturing—it involves the precise control of nanoscale structures to make shapes, devices, machines, and, ultimately, powerful products. It is not hyperbole to say that molecular manufacturing represents the next Industrial Revolution, a tool for radically transforming the world of the early 21st century. Whether that transformation is peaceful and beneficial or horrendously destructive is yet to be determined. Although advanced nanotechnology carries great promise, unwise or malicious use could seriously threaten the survival of the human race. The future of nanotechnology, once the stuff of science fiction, is rapidly approaching reality. We may be less than 15 years away from atomically precise, computer-controlled, inexpensive fabrication of complete products. The social, economic, and geopolitical implications of this technology are staggering. Rapid prototyping will allow product versions to be built and tested in hours. Nanoscale construction will provide direct access to biomedical function at the cellular level. One of the many possibilities is a system that could watch everyone, everywhere, all the time. Such an infrastructure could store, analyze, and index everything it observes and provide a godlike four-dimensional view to whoever controls the system. Like electricity or computers before it, nanotechnology will bring greatly improved efficiency and productivity in many areas of human endeavour. In its mature form, it will have significant impact on almost all industries and all parts of society. Personal nanofactories may offer better built, longer lasting, cleaner, safer, and smarter products for the home, for communications, for medicine, for transportation, for agriculture, and for industry in general. However, as a general-purpose technology, nanotech will be dual-use, meaning that in addition to its civilian applications; it will have military uses as well—making far more powerful weapons and tools of surveillance. Thus, it represents not only wonderful benefits for humanity, but also grave risks. Without some regulation, advanced nanotechnology could be extremely dangerous—but desirable to many people. In addition, manufacturing systems probably will be portable and easy to duplicate. This means it will be hard to control the use of the technology. However, overly restrictive policy will encourage uncontrolled release and a rampant black market. The challenges we face are similar to many not yet solved—but with higher stakes—and today there are many more questions than answers. Because the transformational impacts of molecular manufacturing could occur quickly and with little warning, obtaining a thorough understanding of these issues is essential and urgent.

35 INTERNATIONAL VISITS BY NETWORK MEMBERS Prof Greg Tegart is an adjunct Professor at the Centre for Strategic Economic Studies at Victoria University in Melbourne. He presented a lecture titled “An Australian Viewpoint on Environmental Issues in Nanotechnologies at the Conference on Environmental Effects of Nanoparticles and Nanomaterials in London in September 2006.
Prof Greg Tegart’s report
REPORT ON PARTICIPATION IN CONFERENCE ON “ENVIRONMENTAL
EFFECTS OF NANOPARTICLES AND NANOMATERIALS”,
LONDON, 18/19 SEPTEMBER 2006
Background During preparations for a private trip to Europe in September/October 2006, I became aware of a conference on”Environmental Effects of Nanoparticles and Nanomaterials” to be held in London at the time of my visit there. Given my recent role as Study Leader of the National Academies Forum report on “Environmental, Social, Legal and Ethical Aspects of the Development of Nanotechnologies in Australia”, this seemed an excellent opportunity to gain a view of relevant developments in the UK. I contacted one of the organizers, Dr Richard Handy of the University of Southampton and was invited to participate and give a lecture on the Australian view of the topic. About 80 people attended the conference which was held in the Linnean Society Meeting Room in Burlington House, Piccadilly. Most were from the UK but there were several from Europe and the US.
Format of the Conference There were four sessions covering: Exposure: Environmental Fate and Behavior of Engineered Nanoparticles; Hazard: Effects of Engineered Nanoparticles on Organisms in the Environment; Research Programmes and Opportunities; and Risk Management and Risk Communication. A program with abstracts of the presentations is held by the ARCNN office. Finally, there was a Plenary Session which attempted to draw out a set of conclusions and proposals for action. There was also a poster session which was limited by the available space to 12 posters from post- graduate students. Abstracts of these are given in the program. The main points emerging from each session were:
Session 1 The session dealt with the introduction of engineered nanoparticles into natural aquatic environments. The main point emphasized by several speakers was that there are already a wide variety of nanoparticles of different compositions and shapes in natural systems such as rivers, groundwater and seawater. Some of these arise from leaching of soils producing organic nanoparticles and biopolymers, others from runoff from surfaces through storm water (often containing metallic nanoparticles, e.g. from fuel combustion), some from mechanical breakdown of polymer packaging materials. 36 What happens when engineered nanoparticles are accidentally or deliberately introduced in these environments? As several speakers showed, there are complex interactions at the surfaces of the introduced particles which change their agglomeration behavior, particularly the range of pH in which this occurs. The role of humic acid is particularly important. This has major implications for the proposed use of engineered nanoparticles for remediation of groundwater and supports the strong stand taken in the Royal Society/Royal Academy of Engineering report on limiting such applications until more is understood. These surface interactions can also alter the size and shape of engineered nanoparticles in aqueous environments.
Session 2 The session dealt with the interaction of engineered nanoparticles with living organisms. Several dealt with aquatic species such as fish and mussels while others dealt with soil species such as soil bacteria and earthworms. The two striking results from the aquatic studies were firstly, the difficulty experienced in getting nanomaterials of different types dispersed in water, and secondly the largely negative results of toxicity from a variety of nanomaterials such as fullerenes, carbon nanotubes ,titania, cadmium selenide and polymer spheres. However there were some behavioural changes detected. The first result suggests that accidental escape of nanomaterials into water may be less of a problem than expected because they quickly aggregate and are hard to disperse again, even with ultrasonics. The second result suggests that the organic solvents used to keep nanoparticles in dispersion may have contributed to some of the earlier positive results as suggested by some researchers. Several of the speakers stated that the manufacturers give very little information on their products, making comparison of nominally similar materials difficult. There was little or no evidence of toxicity in the other species studied.
Session 3 The session dealt with activities on environmental studies of nanotechnologies in the US, UK and the EU (both through the Framework Program and in the Joint Research Centre). While there appears to be considerable bureaucratic activity, the money being spent on research in this area is still a small proportion of the total research effort. Many gaps in knowledge have been identified, as noted above, and there is considerable criticism by influential scientists and learned bodies, e.g. the recent two-year review by RS/RAE, of progress of Government actions in response to their report.
Session 4 The session dealt with risk management and risk communication. While the UK is active in trying to develop a “whole-of-government “approach with 5 Task Forces across Departments, they have only just instituted a voluntary reporting scheme for handling of nanomaterials. Again there is criticism that this is insufficient and there are serious gaps and inadequacies in existing regulations. There are fears that industry is moving too rapidly for the regulators. In the case of the EU there are attempts to map gaps in existing regulations from a life cycle perspective. The aim is to use existing regulations where possible and only amend as necessary. However it is clear that the issue of definition of nanomaterials is critical. The existing broad chemical definitions are inadequate and there is work in the US and Europe on categorizing nanomaterials in terms of shape and physical properties. This will be an essential input to the work of ISO/ TC 229 and to Standards Australia activities. I presented a paper on Australia’s activities on environmental aspects of nanotechnologies. The paper was well received and I have established a number of useful links. 37 Plenary Session Time was limited but a number of important topics were identified as: • Need for clear characterization of nanomaterials for research projects on toxicology • Need for manufacturers to be more open about their products, particularly solvents used to maintain dispersion • Are effects due to individual nanoparticles or agglomerations of nanoparticles? • Be prepared for surprises-nanoparticles may behave quite differently in the real world! Complex interactions with other chemicals, organic materials and bacteria can change surface activity and hence behavior. • Breakdown products of nanomaterials need to be considered in toxicity studies. • More research is needed on factors affecting water quality which could alter behavior of nanoparticles. • Food products need to be considered in uptake of nanoparticles –some work on vegetables in the US? • Databases on behavior of engineered nanomaterials may need to be tailored for particular applications. • Risk management needs to be considered more carefully, particularly the application of existing regulations to engineered nanomaterials.
Summing Up There is clearly a need for more work in this area and Australian researchers will need to keep in touch with their colleagues overseas. I distributed some copies of the NanoSafe newsletter to stimulate communication and also gave the website for the NAF report. Richard Handy will write a summary for journal publication. There was strong support for another conference in 2007 and Richard has just informed me that it will be held in London on September 25/26. I hope that Australia can be represented.

38 SHORT TERM VISITS
Mr. Joshua Toomey – visit to the Australian National University ARCNN provided support for Joshua Toomey from Macquarie University whose area of research is chaotic semi conductor lasers. He visited the department of Electronic Material Engineering at the Australian National University to observe and assist with fabrication and preliminary characterization of quantum dot laser devices.

ARCNN Short Visit Report The funding provided by ARCNN was used for travel from Macquarie University (MQU) to the Australian National University (ANU) in Canberra from 27th November to 1st December 2006. The money was spent on travel (petrol costs), accommodation at Ursula Hall at ANU and meals. Summary of benefits: • Established a positive collaboration with the group at ANU. • Knowledge gained from ANU personnel was very useful and has helped to enhance my understanding of nano-scale device manufacturing. • The use of specialised ANU equipment and facilities was extremely beneficial and would not have been possible at my home university. • The detailed characterisation of the laser devices developed will be mutually beneficial for both groups. The goal of this visit was to work with the Electronic Materials Engineering (EME) group at ANU in the fabrication and preliminary characterisation of quantum dot lasers to be used in my PhD project on nonlinear dynamics of semiconductor lasers. I worked primarily with PhD Student Sudha Mokkapati, who processed several devices and went through all the steps with me. Dr Hoe Tan also showed me the steps involved in metal organic chemical vapour deposition (MOCVD) fabrication of the wafer from which the lasers were made. Preliminary characterisation of the devices was carried out while at ANU using standard methods involving measurements of threshold current density, slope efficiency and peak optical wavelength. This characterisation was performed on lasers of various lengths and also lasers with a passive waveguide regions. Several of the devices were then taken to Macquarie University for further high resolution optical frequency spectrum and RF noise characterisation. This has yet to be done as some mechanical workshop parts are required for implementation and some optics need to be sourced. These devices will be mounted appropriately so they may be operated CW and implemented in a feedback system to operate them chaotically. Such a system would have applications in optical secure communication systems. A detailed study of the nonlinear dynamics produced by the system will be performed and any differences which may be attributable to the different forms of the nanofabrication of the devices can be identified. It is likely that a publication will result from these investigations. Another short visit has already been approved for funding and is planned to occur during the first half of 2007. This second visit will be to follow up any issues that arise from further study of the devices back at MQU. It is planned that one goal is to coat the facets of the quantum dot lasers with reflective/anti- reflective coatings. The lasers with integrated passive waveguide section could have one end coating so as to form an integrated external cavity laser. This type of device operating chaotically may have applications in secure communication systems.
39 Mr. Devin Ramdutt – visit to the University of Queensland ARCNN provided support for Devin Ramdutt from the Australian National University whose area of research interest is sputter deposition, thin films, plasma polymers and biotechnological applications and fuel cells.

ARC Nanotechnology Network funding report for lab visit to the Australian Institute for Biotechnology and Nanotechnology (AIBN) at the University of Queensland. As per the details in the grant proposal I, Devin Ramdutt, undertook a week-long trip to the University of Queensland to work with Dr Andre Dicks. The aim of the visit was to discuss several aspect of the collaborative fuel cell project our group has with Dr Dicks as well as begin several experiments on characterisation of different components of a PEM fuel cell. These experiments included proton conductivity measurements, a.c. Electrochemical Impedance Spectroscopy (a.c.EIS) and Cyclic Voltammetry (CV). As the lab in which the work was undertaken had only just been opened, many of the laboratory systems were not operational and much time was spent on setting up the experiment and appreciating the limitations of the new labs. This visit had a very positive effect on the lab, the students and post docs with which I worked as it meant new experiments were possible. I aided in the set up for the use of hydrogen and oxygen gas in the laboratory as well as providing solutions for dealing with the hydrogen exhaust. Hydrogen, oxygen and air humidification systems were also set up including heat baths to maximize water uptake of the gases. There were initial complications with the experiments however these were overcome once the gas humidification system was installed. Both a.c.EIS and CV experiments performed well, with reasonable results obtained, and more importantly, I gained the knowledge to be able to set up those experiments in our lab here in Canberra. Unfortunately the proton conductivity measurements did not go as planned as the results obtained did not correspond to the observed operation of the fuel cell. The issues relating to this may be investigated on a subsequent visit. An example of the measured current/voltage curve is shown below. The measured current for a given voltage was lower by factor of about 2 compared to the results obtained in our lab in Canberra. This is likely to be due to the fuel cell in Canberra being pressurized, giving a larger output power for a given quantity of fuel.
40 Examples of a.c.EIS are shown in the following two graphs. The first graphs shows spectroscopy data for a fuel cell running with a plasma sputtered anode produced in our lab and a commercial reference cathode. The decreasing semi-circle diameter of each spectra correlates with a decrease in the operational voltage. The diameter is a measure of the charge transfer resistance of the fuel cell indicating that as the operating voltage decreases and hence the current flow increase, the resistance to the flow of protons through the conducting membrane in the fuel cell decreases. The second graph is of a single spectrum obtained at 0.4 V for a fuel cell running a plasma sputtered anode and cathode. The main differences between this spectrum and the previous spectra are the large drop on the charge transfer resistance and the fact that the latter spectra crosses the Z′ axis twice. The fact that it crosses the axis at the higher value suggests there is a reduced capacitive effect in the fuel cell, however on the lower end, the spectra drops below zero suggesting a inductive effect. As yet no reason has been found for the marked reduction in the charge transfer resistance although it may have been an error with the data acquisition system as there were initial complications and the first graph was one of the first obtained.
This visit enabled me to discuss with Dr Dicks the future of our ARC funded research project as well as ideas for several papers that will be published in 2007. We were also able to discuss the organization of the World Hydrogen Energy Conference (WHEC) to be held in Brisbane in 2008 for which he is chair, as well as several workshops on hydrogen we wish to organise prior to this event so as to maximise Australia’s input to the conference. As far as I am aware the majority of the goals as set out in the grant proposal have been achieved and the funding has been used appropriately according to the rules of the ARC Nanotechnology Network.

ARCNN OVERSEAS TRAVEL FELLOWSHIP REPORT
CHRISTINA CORTEZ The University of Melbourne, VIC Host: Professor Pierre Schaaf, Institut Charles Sadron, Centre National de la Recherche Scientifique, Université Louis Pasteur, 6 rue Boussingault, 67083 Strasbourg Cedex, France Date of visit: September 4, 2006 – November 27, 2006 The major purpose of the research visit at the Institute of Charles Sadron in Strasbourg was to apply the collaborating group’s expertise on biomaterials in the preparation of drug delivery capsules for cancer cell targeting. Faced with the many challenges that exist when working with biomaterials, I was able to draw on both the skills and expertise of my host group and our own experience to come to a workable system. I gained valuable knowledge in the manipulation of biodegradable systems and gained an insight into other related scientific areas from discussions with other students and scientists at the Institute. The international conference I attended during my visit was also an excellent way to showcase our work in Australia and develop ideas from the interesting science that was presented. In terms of career development, the overseas experience has made me adaptable not only in a different area of study but also in terms of the culture in other scientific institutions. While, scientific result-wise, I did not achieve all that I intended to while in Strasbourg, more importantly, the collaboration between the two groups is continuing with a research fellow from my host group in Strasbourg currently spending time in our lab in Melbourne to further develop this promising collaboration. This, I believe, achieves one of the main aims of this excellent program provided by the ARCNN. A scientific report of my work in Strasbourg is attached and it is anticipated that after further experiments in Melbourne, the report can be submitted as a full publication in a reputable journal. Again, I express my sincere gratitude to the ARCNN for awarding me with an Overseas Travel Fellowship to accomplish this invaluable and enjoyable experience.

Aim of Visit The aim of this visit was to attempt to unambiguously measure electron spin resonance from as few as 10 phosphorus donors in silicon. To achieve this, a new generation of devices was fabricated. These devices have arsenic leads, which have resonant spectra different to that of P. This ensures that any P signal observed is due only to those P donors implanted into the sample region. Also, as the number of spins is so small, we hoped to resolve the spectra of individual donors, which will each have a slightly different resonant frequency due to the random distribution of Si in the material. This would be a major result in semiconductor spin resonance research. Samples were also fabricated on isotopically purified Si. These samples were hoped to show a much longer relaxation time than samples in natural Si, due to the reduction in inhomogeneous broadening of the resonant line, It was hoped this would help increase the sensitivity of the measurements, as well as increase our understanding of the effect of conduction electrons on the decoherence times of the system.
Scientific Benefits of Visit This visit allowed the novel combination of two difficult techniques, nanoscale fabrication by a combination of electron beam lithography and ion-implantation (UNSW/UMelb), and electrically detected magnetic resonance (WSI). A high level of expertise in the fabrication of nano-electronic devices via EBL and ion implantation exists at UNSW. Devices consisting of small implanted clusters of phosphorus in silicon are routinely fabricated, with dimensions as small as 50nm x50n,. The group also has the ability to detect the implantation of a single ion, which provides a pathway to future work on devices with single donors. The group at WSI is a world leader in electrical detection of magnetic resonance. The group possesses several ESR platforms that have been highly customized for EDMR experiments, and thus equipment is integral to the success of these experiments.
Scientific Conclusions The ability to electrically measure the spin resonance of 50 donors in the solid state has been demonstrated. This provides a strong indication that the EDMR method will allow the detection of single spins with the improvements to the sample architecture, particularly by further restricting the current path. EDMR has also been used as a metrology tool, allowing sensitive measurement of the background donor density in isotopic ally purified 28Si. The measurement of that currently
45 available 28Si needs improvement to allow large scale few spin experiments. It has also allowed us to confirm that the isotopic purity of the material is high.
Future Work The results of these experiments are promisiong for future work. By further restricting the current path (perhaps via etching of the sample) it is conceivable that the signal can be greatly increased. This will allow the study of single ions, which can be implanted with unitary control5. Also, it will be interesting to see if the samples used in these experiments are compatible with pulsed EDMR, which would allow the time domain observation of the quantum mechanical effects that underlie quantum information processing.
Other Activities During the visit, I was also fortunate to be invited to speak at the International Workshop in Solid State Based Quantum Information Processing. This 3 day workshop was held at Herrsching, Germany, and was attended by approximated 100 scientists and engineers. The talk I presented was titled “Spin and Charge properties of Si:P probed using ion implanted nanostructures’, and was well received. This was my first invited talk and provided great experience which will contribute to future presentation of my work.
Achievement of Fellowship Aims As well as experimental aims, this visit was intended to enhance the career development of the recipient. Below I outline the ways in which the fellowship aims have been fulfilled.
Career Development During this visit I learned new skills, which will no doubt enhance future career prospects. I will also be able to interact with a number of leaders in the field of few spin detection and isotopic control of semiconductor elements. This has contributed to my understanding of the global directions this research is taking, which will benefit me in career decisions. Also the ability to participate in a complex international collaboration at an early stage of my career has provided me with a good understanding of both the advantages and difficulties of such a venture, which will allow me to develop future similar activities independently.
Skills development and transfer of knowledge The ability to work with one of the worlds leading EDMR groups has added to my ability to perform difficult EDMR experiments, as well as improved my understanding of the underlying processes that contribute to the signal that is observed. This will allow me to improve the design of experiments, improving the likelihood of future achievements in this area. I also gained more insight into the materials problems associated with EDMR of nanostructures. This understanding will be critical for future development of this project towards the single spin element.
Publication It is envisaged that the work undertaken during this visit will be submitted for publication in a leading physics journal. It will also contribute a great deal to my PhD thesis. Initial measurements during this visit were used in a minor way in a submission to Applied Physics Letters, which is currently in the review process. It is my view that the fellowship aims have been fulfilled.

Comment of the fellowship Scheme I would like to make some personal comments on the worth of the Fellowship Scheme from the perspective of a recipient and student. This scheme provides the ability for early career researchers (which I consider myself as a PhD student to be) to benefit from the experience of research in a leading group; in another country. This opportunity, whilst not critical to the success of such a researcher, certainly provides the researcher with a distinct advantage. The ideas and results that arise during research visits tend to surpass those envisaged a t the outset of a collaborative research effort. The mixing of ideas and perspectives in a important component for the success of high quality research. The (comparatively) small community of nanotechnology researchers in Australia benefit greatly from such interactions. As a result, I believe that this scheme is extremely important as a contributor to the continued excellence of the nanotechnology effort in Australia. It is also important that the interaction of early career researchers with other ECR’s is appreciated and encouraged. The cohort supported by this scheme is the one which will provide the leaders of independent research groups in a decade, and the leaders of Australia science in two decade. It is important that these people be given every opportunity to interact with people who will hold similar positions globally. In providing opportunities for this type of interaction, the Fellowship scheme is providing an important service to the future of nanotechnology research in Australia.
Thanks and Acknowledgements I wish to thank the ARC Nanotechnology Network for Travel Fellowship, which enabled my visit to the WSI. I would like to thank Dr Martin Brandt for allowing me to visit and work in his group at the WSI, as well as providing great insight into the experimental work undertaken. I would also like to thank Hans Huebl, a PhD student in the group, for the time and effort he has contributed in teaching me the basics of EDMR measurements and to the subsequent analysis of the data, Thanks also to all the staff and students at the WSI who made the visit such a memorable scientific and social adventure. Thanks must also go to the ARC Centre of Excellence for Quantum Computer Technology, and my supervisor Professor Robert Clark for additional financial support, as well as the opportunity to participate in such a worthwhile collaboration.

Mr. Jasek Jasieniak – visit to the University of Padua, Italy. ARCNN provided support for Mr Jasek Jasieniak from the University of Melbourne to visit the University of Padua in Italy. His area of research is synthesis of highly luminescent II_VI semiconductor nanocrystals and their surface properties. His application was supported by his supervisor Professor Paul Mulvaney and Professor Alessandro Martucci from the University of Padua.
Copy of report from Jasek Jasieniak. ARCNN Overseas Travel Report Period Spent at the University of Padova 9th April – 9th July
Background The rapid progression of knowledge in nanoparticle surface functionalization over the last ten years has led to a significant increase in the understanding of specific solvent-ligand and ligand- surface interactions. By carefully manipulating the surface chemistry of nanoparticles through the judicious use of selective bi-function ligands, solubility can now be afforded in almost any imaginable solvent. Only recently however, has this understanding been extended to the use of high-quality nanoparticles as ‘building-blocks’ in various solid-state host-matrices. Our own efforts have already shown that such systems can exhibit some truly unique properties, and in particular with regards to this project, extremely high yields of photoluminescence. For nanometer sized semiconductor nanoparticles the emission wavelength is strongly dependent on their radius. This means that the emission wavelength can be readily tuned; in the case of CdSe this tunability occurs over the entire visible spectrum.
Project Goals The main goal of this project was to combine engineered CdSe based nanocrystals and sol-gel matrices thereby creating highly luminescent inorganic composites. By combining the highest quality nanoparticles and the most appropriate sol-gel matrices we endeavoured to determine the factors that will contribute to photo-stability of both spontaneous emission, and amplified stimulated emission in such systems. The second branch of research was based on using the x-ray lithography facilities at Eletrra to pattern quantum dot doped sol-gel matrices for the purpose of advance composite waveguide generation. By using an appropriate mask we aimed to fabricate microscopic structures that were highly luminescent with potential use as optically active pillar waveguides.
Project Outcomes and Future Outlook By utilizing the facilities at a number of research institutions, significant progress was made with regards to the main objectives of this project. The three month project, funded in part through the ARCNN overseas travel fellowship, has pushed the materials beyond what was thought possible before the project was undertaken. It was determined that this matrix possesses both a high refractive index and is ‘compatible’ with CdSe based quantum dots. This selection of matrix also led to a high degree of photo-stability of the nanoparticles in air and at room
48 temperature. Furthermore near stable amplified stimulated emission was observed for nanocrystals in ZrO2 matrices. Lithographically patterning quantum dot composite structures was also highly successful. During the time allocated on the LILIT beamline, microscopic structures were etched into the composite material, resulting in highly luminescent and well defined structures. Linear ridge waveguide geometries were clearly achieved (see Figure 1), however the high aspect ratios required for the pillar structures caused for composite-substrate adhesion problems. X-ray beam time is the most vital ingredient for further progress, and it is hoped that the experience gained at Eletrra can be utilized when the new synchrotron is operational in Melbourne.
Figure 1: Etched structures of (a) green and (b) red QDs in an organically modified SiO2-ZrO2 composite. Acquired Skills: The main objective of my project is the development of quantum dot devices. While in Italy we managed to show the stable quantum dot ‘lasing’. In this process, skills were acquired in setting up femto-second lasers and the associated hands-on skills necessary to take lasing measurements. Since arriving back in Australia, I have managed to observe lasing here at the University of Melbourne, which is indeed an indication that the skills learnt overseas were beneficial for my project here. Additionally, I had experience in using the lithographic facilities at the Eletrra synchrotron. This provided me with a sound basis on what procedures are involved in lithographic process. While these skills are not essential to my project here in Melbourne, they may be in the future with a lithographic station being opening up here at the Melbourne synchrotron soon
General Comments The expertise in sol-gel chemistry provided by both my hosting supervisor and the Italian PhD students were invaluable. Establishing reproducible methodologies of incorporating nanoparticles into sol-gel matrices was a vital step for my PhD project and in this regard it has meant that a lot of progress has come quickly. Moreover the contacts that I made during the trip have created a lot of opportunities for me following my PhD candidature. I would like to personally thank the ARCNN and the ARC for offering me the overseas travel scholarship. The backing provided me with adequate funds to visit Eletrra twice, afford food and accommodation, not to mention piece of mind in a foreign country. Furthermore, I am delighted to inform the council that I will acknowledge the financial backing that I have received through the ARCNN overseas travel scholarship in two forthcoming publications. The trip was one of great success for me personally and academically. 49
Mr. Toby Hopf – visit to the Lawrence Berkeley National Laboratory, USA. ARCNN provided support for Mr Toby Hopf from the University of Melbourne to visit the Lawrence Berkeley National Laboratory. His area of research is creation of nanoscale devices fabricated by the counted implantation of single atoms, using a low-energy ion beam. His application was supported by his supervisor Professor David Jamieson and Professor Alessandro Martucci from the University of Padua.
REPORT ON OUTCOMES OF OVERSEAS TRAVEL FELLOWSHIP I spent approximately eight weeks at the Lawrence Berkeley National Laboratory in the period of September – October 2006, undertaking research utilizing a highly-charged ion beam in Dr. Thomas Schenkel’s group. The major aim of this research was to see whether highly-charged ions could be used to facilitate the detection of single ions implanted into a silicon substrate. In Melbourne we have developed and optimized a technique for the detection of single low-energy phosphorus ions implanted into silicon, that uses the impact of 31P+ ions to generate an ionization signal in the substrate, which is then collected to verify the implantation of a single ion. It was hoped that the use of higher charge states – with their higher associated potential energy – would lead to an increase in this ionization signal, and so be a useful improvement to the single ion detection technique. In order to perform these experiments, a number of detectors that had been fabricated in Melbourne were brought up to the Lawrence Berkeley Lab. These detectors first had to be integrated into the ion beam chamber there, which required significant modifications to the sample holder stage, and then the electronic noise of this system had to reduced to an acceptable level, which also required further changes. This work occupied the first four weeks of my time at the lab. The last four weeks were taken up with doing the actual experiments. The main focus of the work was to do a series of implants with ions of an equal kinetic energy but with differing charge states (and hence potential energies) to see the effect this had on the total ionization generated by the ions. It was found, counter-intuitively, that for both argon and xenon ions the total ionization obtained actually decreased as the charge state of the ions increased. These unexpected results can be explained as a combination of two effects. Firstly, the highly-charged ions are completely neutralized within the 5 nm surface oxide layer that lies on top of the detector substrate, and hence deposit all of their excess potential energy in this oxide layer. Since the mean free path of carriers generated in the oxide will be extremely low (less than 1 nm), very few of these will actually be able to make it to the silicon detection area, and so will not be able to contribute to the ionization signal. This first effect explains why there is no increase seen in ionization signals for highly-charged ions, but it does not explain the actual decrease in the signal. To justify this, one must look to the 1993 paper of J.P. Biersack (Nucl. Inst. & Meth. B, 80 (1993) 12-15), who showed that the nuclear stopping power in silicon dioxide is greatly increased by an increase in the charge state of the incident ion. For this reason, highly- charged ions traversing the 5 nm oxide surface layer will experience an increased rate of stopping, losing more of their energy within this region, and hence enter the silicon with a lower energy than an ion with a lower charge state. This effect can explain the decrease in the ionization signal with increasing charge state that was observed in our experiments. After returning from Berkeley, this work has subsequently been presented as a poster at the Australian Institute of Physics 17th National Congress in Brisbane, and we are currently working to turn it into a paper to be published in a peer-reviewed journal.

SCHOOL OF CHEMISTRY Dr. Wenrong Yang SYDNEY 2052 AUSTRALIA
February 12, 2007
In this report, I summarized my scientific visit to Prof. Shen Ye’s group at Hokkaido University in Japan, the research project we have been working is Exploiting Electron Transfer Properties of Norbornylogous Bridges for Advanced Electronics Materials. Self-assmbly of monolayers of Norbornylogous bridges covalently bound to gold electrodes has been studied in situ FT-IR with electrochemistry. We have clearly demonstrated a relatively straightforward method for measuring spatial orientation between the redox molecules (Fc) on the end of the bridges and the surface. The knowledge gained will be exploited in the development of novel biosensors for environmental and health monitoring and new highly efficient solar cells for energy conversion. I have learned some of the important skills in surface vibration spectroscopy and preparation technique of gold single crystals through this visit. Based on this visit, I have established a close contact with Prof. Shen Ye about our research, and we have been working on the details of the project. Following manuscripts are preparing for publication at high quality international journals. • Monitoring Electron Transfer in Norbornylogous Bridges Self-Assembled Monolayer by in Situ Infrared Reflection Absorption Spectroscopy
Further, this visit undoubtedly gave me a great opportunity to establish a long-term collaboration with Prof. Shen Ye’s group at Hokkaido University in Japan. Through this visit, it would be greatly helpful for my future research.

Mr. Thomas Rufford – visit to the National Institute of Advances Industrial Science and Technology, Tsukuba, Japan.
Scope of Report This report describes a research visit by Thomas Rufford, a PhD student in the ARC Centre for Functional Nanomaterials at the University of Queensland, to the Energy Storage Materials Group of the National Institute of Advanced Industrial Science and Technology (AIST), Tsukuba, Japan. The visit was supported financially by an Australian Research Council Nanotechnology Network Overseas Travel Fellowship.
Host Institute Background My visit at AIST was to the Energy Technology Research Institute (ETRI) in Tsukuba. My collaboration in the ETRI was with the Energy Storage Materials Group led by Dr Hiroaki Hatori. Dr Hatori’s group studies the preparation and properties of carbon materials for applications such as capacitors, carbon electrodes and hydrogen storage.
Scientific Background Hydrogen is considered one of the best alternatives energy carriers to fossil-fuels as it can be utilised cleanly in a fuel cell. However, a key technical challenge to the wide spread use of hydrogen in mobile applications is the development of effective hydrogen storage technologies. The conventional methods of storing hydrogen as a cryogenic liquid or a high-pressure compressed gas are restricted by the high energy cost of the liquefaction and compression processes, and by their low volumetric hydrogen densities. Metal hydrides and high surface area materials, such as carbon, are alternatives to the conventional hydrogen storage technologies. My current research concerns production of magnesium – carbon nanomaterials for hydrogen storage from a “bottom-up-approach” rather than the “top-down” milling approach abundant in the literature.
Visit Objectives The scientific objectives of the visit, as stated in the fellowship application, were:
• To design a method for synthesising magnesium hydride (MgH2) nanoparticles within the pores of the carbon structure, and • To evaluate the carbon-magnesium hydride materials for use as hydrogen storage materials.
This study involved the synthesis of magnesium loaded activated carbon fibre (Mg loaded ACF), investigation of the thermal decomposition of the magnesium precursors on the ACF by thermogravimetric analysis (TGA) and temperature programmed desorption (TPD), and finally measurement of the H2 adsorption capacity of the Mg loaded ACF.
Scientific Conclusions In this work we have identified a set of conditions required for the synthesis of Mg loaded carbon. We found that under N2 and H2 it was possible to reduce MgCl2 impregnated on ACF as observed by TGA. However the nature of the Mg on the ACF surface has not yet been confirmed by any compositional analysis. TPD-MS measurement confirmed that MgCl2 did not have a catalytic effect on the gasification of the carbon support under H2 gas flow.
52 SEM images of MgCl2 loaded ACF treated under Argon and later exposed to air show a thin layer, approximately 1 μm thickness, of a non-conductive MgO on the surface of the ACF.
At 300ºC and an initial pressure of 2.25 MPa the overall H2 uptake on the Mg loaded ACF material prepared from MgCl2 was just 0.4%wt after 1200 minutes. Whilst the overall uptake on the Mg loaded ACF material is well below the required capacity for a practical H2 storage material, when considered on the basis of H2 uptake on the Mg, only the Mg loaded on ACF exhibits improved H2 uptake and kinetics compared to the powder Mg material.
Future Work The research completed during the visit to AIST has helped to identify a synthesis route for Mg loaded carbon. However, several key questions are still to be addressed in this work. For example, compositional analysis of the Mg loaded ACF after heat treatment is required to confirm the state of the Mg on the carbon surface. The transfer of Mg containing samples between synthesis apparatus and characterisation instruments without exposure to air, or moisture, remains a challenge and we are continuing to investigate appropriate techniques for this analysis. During the three month visit it was not possible to complete all planned TPD experiments and we chose to focus on the MgCl2 loaded ACF whilst I was in Japan. The TPD analysis of Mg(NO3)2 loaded ACF remains of interest for the study of high surface area carbon materials, a product of the thermal decomposition NO2 being a known carbon activating agent. Dr Takagi will continue these TPD experiments from April 2007. I will continue to work on Mg loaded carbon materials for my PhD research. The next phase of my project will focus on increasing the Mg loading on the carbon support, including the use of carbon materials with mesoporous structure. Further H2 storage measurements will be conducted at the University of Queensland during 2007.
Other Activities Other activities completed during my stay in Japan included: • A seminar on the work conducted during the visit presented to members of the Energy Storage Materials Group. • A one day visit to the Suzuki Shokan Gas Equipment factory for inspection and training in use of a high-pressure H2 adsorption instrument recently purchased by UQ. This instrument was installed at the ARC Centre for Functional Nanomaterials at UQ in January 2007. • Attendance at the 2007 Fuel Cell and Hydrogen Technology Exhibition held in Kitakyushuu. Highlights of the exhibition included a ride in a Toyota Hydrogen Fuel Cell Vehicle (HFCV), a demonstration hydrogen refuelling bowser, discussions with several researchers in the field of hydrogen storage technology and a tour of the All Nippon Steel Company’s hydrogen production plant and paper recycling plant.
Achievement of Fellowship Aims
Career Development Access to the equipment at AIST during my visit allowed the collection of a large amount of data on the process of magnesium – carbon nanostructure synthesis. This has allowed me to progress my PhD research more quickly than I could have at the University of Queensland facilities. At this stage of my research career submitting a quality PhD thesis within an acceptable time frame is my highest priority career goal. 53 The ARCNN Overseas Fellowship has allowed me to be involved in an international collaboration project at an early stage of my research career. Through this project I have gained a better understanding of key factors required to make international collaborations a success, such as the need for detailed planning of experiments in advance, assigning clear responsibilities between the parties involved and maintaining effective communication throughout the life of the project. In regards to more general career development, living in Tsukuba provided the opportunity for interaction with researchers from a wide range of scientific fields and from many different countries. High quality nanoscience and nanotechnology research is being conducted at a number of institutes in Tsukuba. During informal interactions with other scientists I learnt about interesting research currently occurring not just in Japan but in other parts of the world. The network of friendships formed will be very useful when considering future employment opportunities.
Skills Development Key skills developed during this scientific visit included: • Rotary evaporation technique for impregnation of metals on high surface area materials. • Extensive use of thermal gravimetric analysis (TGA). While I had previously used this technique at UQ whilst I was at AIST I was the only researcher using the TGA in the lab and thus was able to learn a great deal about the limitations of the technique and maintenance of the instrument. • Temperature programmed desorption coupled with mass spectrometry. Under the supervision of Dr Takagi I developed skills in designing experiments, carrying out measurements and analysing data from the TPD-MS instrument. • Handling of materials under an inert atmosphere in glove-box. • Basic Japanese language skills, as well as an increased understanding of the Japanese cultural and scientific working environments.
Knowledge Transfer Dr Hatori’s group at AIST are experts in the field of nanostructured carbon materials and during this visit I gained knowledge on various carbon synthesis techniques, characterisation methods and property testing. Outside of my own project area, I was able to learn from the other group members about electrochemical testing of carbon materials for application of capacitors. I brought to the Energy Storage Materials Group knowledge of the use of metal hydrides as hydrogen storage materials and also knowledge of different industrial processes from my previous experience as an oil refinery engineer. I was able to discuss my experiences with various hydrocarbon catalyst processes with the researchers at AIST.
Publishing Plans We expect to be able to publish at least one paper on the decomposition of Mg salts on carbon materials. However, as previously mentioned there are several questions that need to be addressed in this work before finalisation of a paper. There is the possibility of a second paper on the hydrogen storage properties of the Mg loaded ACF following completion of the hydrogen storage measurements at UQ later in 2007.
Scope for future collaborations
54 My visit to AIST built on an existing link between the Energy Storage Materials Group at AIST and the ARC Centre for Functional Nanomaterials at UQ. Dr Takagi and I still have further work to complete on the Mg loaded carbon project and we will both be continuing this work in 2007. Dr Takagi and I have discussed the possibility of working together on this project and possibly other carbon nanomaterial projects in the future. The collaboration between AIST and UQ will continue with another student from UQ planning a visit to the Energy Storage Materials Group to work with Dr Takagi in late 2007.
Acknowledgements I would like to acknowledge the ARC Nanotechnology Network for the financial support of this visit to the AIST Japan. I am extremely grateful to the host researchers Dr Hideyuki Takagi and group leader Dr Hiaroki Hatori for facilitating my visit to AIST and for their scientific guidance during my stay. I also wish to acknowledge the assistance provided by the other members of the Energy Storage Materials Group laboratory. Thank-you to the ARC Centre for Functional Nanomaterials at the University of Queensland and my PhD supervisors Professor Max Lu and Dr John Zhu for additional financial support. Thanks also to Sharon Mathiesen for her ongoing administration support. Finally I wish to thank all those in Tsukuba who helped make my visit productive and enjoyable, and taught me about many aspects of Japanese culture. In particular I wish to thank the staff of the JST Ninomiya House for their friendly assistance during my stay. I can recommend Ninomiya House as a convenient and comfortable place to live for foreign researchers visiting Tsukuba.

YOUNG NANOTECHNOLOGY AMBASSADOR AWARDS
The Young Nanotechnology Ambassador Awards were set up to promote science and science education in state and territory schools. Two awards are provided per state/territory and each award is valued up to $2000.
The young nanotechnology ambassadors are required to visit a minimum of four schools (preferably at least one regional school) to inspire students about nanotechnology, and more broadly science education. It is up to the ambassadors to decide which schools they visit and to arrange these visits with the schools. The ambassadors are encouraged to present a talk which could include visual demonstrations or simple experiments, slide shows or other multimedia presentations.
The following are the Young Nanoscience Ambassadors for 2006. • Australian Capital Territory

Mr. Melvin Lim (University of Queensland) –Whitsunday Anglican School, Robina State High School,Moresby & Mission Beach State Schools ,Indooroopilly State High School
Young Nanotechnology Ambassador – Melvin Lim (ARCCFN, UQ)
Report on recently completed schools’ visits, Sep – Nov 2006 In September/October 2006, a good mix of Australian schools (primary and secondary) were contacted to gauge the level of interest present in organizing potential visits to their schools, as part of the initiative under the Young Nanotechnology Ambassador Award scheme. These proposed visits presented a twin-fold objective. Firstly, it was of the intention to introduce nanotechnology at a fundamental level to students and teachers of science. Secondly, it was sought to encourage spontaneity in the targeted audience in developing an interest in nanotechnology, and develop an understanding of the critical issues underlying it. The Principals or Heads-of-Departments of schools were a first point of contact in organizing the proposed visits. Preliminary discussions regarding these visits were met with good overall enthusiasm from staff members of the schools. The actual visits, which lasted between 2-4 hours, generally included a basic presentation serving as an introduction to nanotechnology, various experiment demonstrations or the viewing of videos to illustrate certain processes or concepts used in the field of nanotechnology, and audience-presenter discussion sessions. The schools visited included: Whitsunday Anglican School (Mackay, 40 students Yrs. 8-10) Robina State High School (Gold Coast, 60 students Yrs. 11-12) Indooroopilly State High School (Brisbane, 45 students, Yrs.11-12) Moresby & Mission Beach State Schools (Innisfail, 25 students, Yrs. 3-7)
During the combined visit to Moresby/Mission Beach State Schools, an exciting challenge was presented – the audience, made up of young minds ranging from the ages of 9 to 12, were simultaneously preparing to enter the First Lego League (an annual competition which is organized globally, and based on the themes of nanotechnology and robotics). The students were keen to learn more about tiny entities, and this was echoed in them applying their newfound ideas (and freedom) to using Lego bricks as building blocks for their project. This visit also drew the attention of the local newspaper (Innisfail Advocate), and exposed the importance of nanotechnology further to the local community. The concluding discussion sessions in visits were deemed to be particularly important to judge the success of the visits. In fact, in most schools, frequent and thought-provoking questions emerged from both staff and students, and it is of the opinion that the general involved audience not only followed or assimilated the ideas and concepts of nanotechnology that were presented, but were eager to contribute their afterthoughts. In conclusion, the visits to the schools were very well-received, based on the level of interest generated in the audiences. Accolades were also received from staff members, many of whom were keen to have the next batch of Young Nanotechnology Ambassadors visit their schools again.

Interim Report to ARCNN in regards to 2006/2007 Young Ambassador (VIC) Program. Using the resources provided by La Trobe University and the ARCNN, a nanotechnology workshop has been designed and delivered to various schools around Victoria. The schools visited so far are, Mill Park Secondary College, St Helena Secondary College, Eltham College. Northcote High School is to be visited in the coming weeks. So far over 120 students have attended the workshop with approximately another 75 scheduled to participate shortly. The program consists of a presentation on nanotechnology followed by two short experimental activities. The presentation discusses; • What nanotechnology is; • the principles behind it; • its applications and • potential nanotechnology career paths.
The two experimental activities were designed to introduce the students some of the various methods of manufacture and analysis associated with nanoscience. The two activities where as follows; • The first activity involved the students synthesising gold nanoparticles and investigating some of their properties optical. • The second activity involved the use laser diffraction to determine the diameter of the student’s hair.
Further information regarding the specifics of the activities can be found in the attached documentation. All aspects of the workshop have been well received by both the staff and students of the schools.

School Specific Info: Mill Park: Two sessions were, delivered to two Year 11 physics classes. The presentation was given and hair diffraction experiment was run. As it was a physics class the teacher requested that the gold colloid activity was not undertaken. St Helena: Two sessions were undertaken with the Year 11 chemistry classes. All activities were preformed. At the request of the Science co-ordinator, Daniel Langley a 2nd Year Nanotech student who participated in the La Trobe University Into Science Peer Mentoring program, assisted in the demonstrations. As the school was developing they’re own nanotechnology unit the workshop was well received. Eltham College: Two sessions were run with the Year 11 chemistry classes (see attached images). Greg Barbante assisted with the session. The gold colloid method was modified to remove the need for stirring of the solution, this produced a lower (but still acceptable) grade of colloidal gold. It was also realised that the quality of water used is of utmost importance, with normal deionised water resulting in larger particle size. Using dense salt water bilayers of gold colloids were produced by the students as shown in image 2. Northcote High School: Two sessions to cover three classes have been organised and are due to be run shortly. Other schools are have been invited to undertake the program however as yet have organised a date to undertake the session.

SUMMARY OF OUTCOMES My PhD thesis aims to advance our fundamental understanding of the electronic structure of cerium oxides with reference to their application as catalytic materials in high-temperature solid- oxide fuel cells. The key challenge in developing an accurate and unified theory of the catalytic physics and chemistry of cerium oxides lies in the problem of finding an accurate description of the ‘f’ electrons in these systems. The ‘f’ electrons in especially the more reduced forms of cerium oxides apparently exhibit somewhat intractable ‘many-body’ effects which therefore require advanced many-body theory for an accurate description. My main goal in attending the ARCNN Summer School was to learn some state-of-the-art theoretical tools from advanced many-body theory for possible application to the cerium systems I am studying. I summarise, below, the main outcomes from this Summer School for me relative to this goal.
THEORETICAL TOOLS The three key results are: 1. The Tight-binding Model: The development of the tight-binding approximation starting from the elementary Heitler-London approach for the H2 molecule to extended crystalline solids provided me with some new intuitive insights into the electronic structures of crystalline solids. I am right now developing tight-binding model descriptions of my cerium systems and finding the process incredibly rewarding as I am beginning to ‘see’ the many-body interactions which are crucial for an accurate electronic structure description of these materials. 2. The Hubbard Model: Although this model is a very simplified view of the actual electronic physics of real materials, its conceptual elegance provides a fruitful framework for understanding the physics of strongly-correlated electron systems. I had good practice from the many tutorial questions prepared for the Summer School to now sufficiently understand the model in a ‘hands-on’ manner. I will be using concepts from the Hubbard model to develop a ‘minimal model Hamiltonian’ approach to the cerium systems – see below. 3. The Minimal Model Hamiltonian Approach: This is an approach which seeks to capture the essential physics relevant to a particular problem. The approach can be used together with the standard Density Functional Theory (DFT) methods to get a more accurate description of the electronic physics of strongly-correlated systems. This tool will form the backbone of my thesis and this Summer School was invaluable in helping me acquire the fundamentals of this method. More work still needs to be done but the Summer School offered the opportunity for a great start.
COLLABORATIVE OPPORTUNITIES I met a crystallographer from the University of Sydney whom I am now interacting with for a better understanding of some crystal topologies of the cerium systems.
OTHER I had the opportunity to present a poster of my work to date to an audience who had good knowledge of my area of research. I got some useful suggestions from the poster session. Report Prepared for ARCNN by: Elvis Shoko,Department of Physics,University of Queensland

Electromaterials Science Symposium- The role of nanostructure
Purpose The ARC Centre of Excellence for Electromaterials Science (ACES) hosted the first national symposium on electromaterials science in February 2006; an event consisting of a 2 day symposium and 2 day training workshop. Introduction of the world’s strongest artificial muscles, the announcement of a patent involving a new sensor that will have special environmental implications and the latest wearable solar cells and fibre batteries on clothing was among highlights at the first international symposium on electromaterials science Researchers from the world’s leading scientific institutions including Germany,Italy, France, USA, Canada, The Netherlands, Ireland, Australia and New Zealand participated in the symposium, as well as industrial colleagues from a variety of disciplines. Topics were selected that probed the enormous potential of nano (ultra minute) technology at the interface of science and engineering.
Outcomes of the symposium: The symposium program consisted on 17 oral presentations and 56 posters, covering such topics as the synthesis of conducting polymers, carbon nanotubes, other nanomaterials, nanofibres, and ionic liquids; and their applications in areas as diverse as solar cells, batteries, biofuel cells, thermoelectrochemical cells, actuators, sensors, and bionics. Described below are some of the highlights from the research presented: o An extraordinary finding that has implications in the development of stronger artificial muscles and even wearable energy storage (fibre battery structures). The addition of just small amounts of carbon nanotubes (large macromolecules that are unique for their size, shape and remarkable physical properties) increases both the mechanical and electrical properties of conducting polymer fibres. This finding along with work on the use of textile coated materials as battery components brings the area of wearable electronics closer to reality. During the symposium, Professor Danilo deRossi from Italy presented the latest work on e-textiles for biomedicine.
75 o A range of polymers that can respond to small electrical stimuli to release active molecules (such as drugs or growth factors) have been developed. It is envisaged that these new controlled release systems will play an important role in the bionics program within the ARC Centre of Excellence. o The latest developments with research into improving the performance of bionic ear implants with a presentation from the inventor of the Bionic Ear, Professor Graeme Clark sparked significant interest. o Five undergraduate students who won summer research fellowships to undertake projects within the Intelligent Polymer Research Institute presented the results of their studies at the symposium. The summer fellowship holders have been working on projects spanning the use of nanotechnology in thermoelectrochemical cells (harvesting energy from waste heat), to nanotube electrodes for biofuel cells and harvesting energy from biological systems. o An ethics workshop chaired by Associate Professor Susan Dodds raised basic awareness of the social and ethical issues that arise from developments in nanoscience and nanotechnology, and the workshop encouraged critical discussion about the implications. o Industrial participation was encouraged, with a number of industrial representatives attending the symposium. During various networking sessions, Centre staff raised the concept of associate membership, and discussions are ongoing as to how to formalise relationships between individual companies and the Centre.
Outcomes of the training workshop: As a precursor to the symposium, ACES conducted a 2½ day workshop program, with a specific focus on the training of young researchers within the Centre. The workshops were attended by 30 - 40 students and staff. Training was carried out by a team of eminent researchers who are international experts in their field – the program and topics are contained within Schedule 1.
The workshops covered topics on mechanical properties of polymers, modelling of polymer systems, and electrochemical methods. These topics provided: (i) an introduction to the mechanical behaviour of polymers and approaches to modelling materials properties and systems, with a particular focus on the nanoscale; and (ii) introduced/reinforced electrochemistry basics and advanced use of equipment to achieve characterization of nanostructured electromaterials and optimisation of nanomaterial properties. Techniques discussed for characterisation and optimisation were ESR/E-chem Raman spectroscopy, Fourier Transform Techniques and Electrochemical Mapping and Impedence Spectroscopy. Participants were also given the opportunity to hear about electrochemical surface engineering for production & characterisation of novel coatings, preparation and properties of nanoparticle composite coatings, photoelectrochemical cells and thermoelectrochemical cells.

Asia Pacific Conference on Plasma, Science and Technology
Report on APCPST2006 The 8th Asia-Pacific Conference on Plasma Science and Technology (APCPST) took place in the Novotel Palm Cove Resort in Cairns during the first week of July 2006 (2-5th July 2006). It was organized by the Space Plasma Power and Propulsion group of the Australian National University. The conference started on Sunday evening (2nd July) by the welcome reception. The presentations were on Monday, Tuesday and Wednesday. The banquet dinner took place on Tuesday evening. APCPST8 started off rather slowly. In fact, by the time of the first registration deadline in April 2006, we had a grand sum total of two (2)!!! Considering it judicious to extend the deadline, we proceeded into a sequence of extensions until there were at least 100 full registrations. Three weeks before the conference itself there were around 150 attending and we then ordered the conference bags, programmes, T shirts and wine. We actually over ordered for 180 so there would be a surplus. On the day we started the conference there were about 174 registered but to our surprise another 35 or so registered at the conference so the grand total was a tad over 210 attendees (as far as we can estimate). Initially we intended to have Tuesday afternoon for an excursion but with the increase in attendance this was not possible; the conference was also extended by ½ hour in the mornings and evenings. This conference the best APCPST we have had in Australia. The 4 poster sessions were very well attended and many new collaborations started. Around 150 researchers presented posters at their request which was surprising at first. However, having watched the dynamic of the group it became clear that the majority of the presenters were students and ECRs from China, Korea and Japan. They felt that it was much easier to present their work in an environment containing a few people who could ask questions. Given their different cultural and language backgrounds posters were a much better choice than oral presentations. This is opposite to the general feeling of European based societies. The general theme was materials and thin films fabricated by plasma techniques with a large number of presentations focusing on nano-scale depositions. The students and ECRs made up about 75% of the conference attendance and it is due to these people that the conference was a great success. Full details of the presentations and programme can be found at: http://wwwrsphysse.anu.edu.au/~mdl112/apcpst/ In 2008 we will be in China and Prof Wu is the conference chair. APCPST8 wish him all the best! Here is the list. Wendy distributed the money equally between the flights and rego up to the maximum of $5k. The ARCNN was a welcome contribution to these costs.

International Conference on Optical & Opto Electronic Materials & Applications
ARCNN Sponsorship for ICOOPMA2006
Report The first International Conference on Optical and Optoelectronic Properties of Materials and Applications, ICOOPMA2006, was held in Darwin, during 16-20 July 2006. The ARCNN Management Committee had kindly supported the conference with a sponsorship of $5000.00. ICOOPMA2006 had attracted 126 delegates from 23 countries. The conference started with the registration, 1500 -1700 hrs on 16 July 2006 (Sunday), and academic sessions started from Monday morning. There was one plenary session with two plenary speakers, 11 sessions were devoted to the oral presentations including invited ones and two poster sessions. There were 35 invited speakers, including the plenary ones. There were two parallel sessions covering a very wide range of optoelectronic materials, from photovoltaic materials to organics for displays. ICOOPMA2006 was sponsored by the Charles Darwin University, ARC Nanotechnology Network, Springer, Wiley, OzOptics (Canada), and Perkin Elmer. One of the main aims of the conference was to bring together researchers in this field from all over the world to exchange new ideas, and present their results in a congenial atmosphere and at an attractive location that entices people to visit. Papers presented were regarded to be of high quality in a wide variety of fields in optics and optoelectronics. All papers presented at the ICOOPMA2006 and submitted for inclusion in the conference proceedings will be refereed and accepted ones will be published in a special volume of the Journal Materials Science: Materials in Electronics published by Springer. It is expected that the refereeing process of the submitted manuscript will be completed before the end of 2006 and the proceedings will be published by mid 2007. ARCNN sponsorship was used to support the registration fee for two Australian graduate students and 11 invited speakers. The spreadsheet of the disbursement of funds is attached. I would like to thank the ARCNN Management Committee for the sponsorship.

Ethics and Regulation in Nanotechnology Workshops Report on workshops on Ethics and Regulations in Nanotechnology undertaken by the ARC Centre for Electromaterials Science (ACES) with sponsorship by ARCNN. The Ethics and Regulation Workshops were two half-day events (at Monash University and at theUniversity of Wollongong), supported through ACES and ARCNN for early career researchers and HDRcandidates working in nanotechnology. The Workshops provided participants with an introduction to some emerging ethical and regulatory issues in nanoscience and nanotechnology; an opportunity to develop skills in identifying and articulating responses to ethical and regulatory issues through case studies; and an opportunity to meet, debate and hear the views of some key Australian researchers and practitioners in the areas of nanoethics and nanoregulation. The workshops on ethics and regulation in nanotechnology were held in August 2006 at two venues, Wollongong and Monash. The events were hosted by ACES and partly sponsored by the ARC Nanotechnology Network.These two workshops were well-attended (approximately 35 participants at Wollongong and 18 atMonash) and well-received. Prof. Susan Dodds developed the case studies and facilitated the workshops. There were four invited speakers and support from Prof. William Price (Wollongong) and Prof. Maria Forsyth (Monash) as well as other ACES staff. Each invited speaker presented their overview of the key issues for regulators and ethicists as these technologies emerge. At Wollongong the presenters were Prof John Weckert (Information Technology, Charles Sturt University and ARC Key Centre for Applied Philosophy and Public Ethics); Ms Diana Bowman (Law, Monash University) and Dr Peter Binks (NanoVic). At Monash Dr Rob Sparrow (Philosophy and Bioethics, Monash University) replaced Prof Weckert; Diana Bowman and Peter Binks presented at both workshops. Participants were encouraged to read the 2006 UNESCO Publication The Ethics and Politics of Nanotechnology prior to the workshops. At both workshops, participants were given the opportunity to work through some of the ethical and regulatory issues of nanotechnology through two cases. In the first, participants were asked to develop criteria for research assessors who were to set priorities in research funding based on the “national benefit” of nanotechnology research. This required participants to identify the different kinds of “goods” that nanoscience/ nanotechnology could generate, their relative importance for a society like Australia, the relative likelihood of different benefits being achieved in the foreseeable future and the significance of allocating public funding to different research areas. The second case asked participants to identify what for that group were considered to be the key factors of nanotechnologies that required some form of regulatory response; to explain why those factors were significant; and to explain what kind of regulatory structure would be appropriate for those concerns. All presenters offered commentary on the group discussion findings. There were difficulties in advertising to interested participants external to the Centre given a short timeframe. It is anticipated that the workshops will be run again next year with the prospect of attracting larger numbers of delegates external to ACES.

85 Materials and Complexity IV Workshop Report on the Workshop on “Materials and Complexity IV” held at Kioloa 14-17 November, 2006.
Kioloa workshop participants of Materials and Complexity IV. Picture taken on the warmer last day. This annual workshop, which has now been held for six consecutive years, took place from 14- 18 November at the ANU’s Kioloa campus, a relaxed venue on the NSW south coast, offering an ideal environment to stimulate scientific discussions. For the last four years the workshop centered on the theme “Materials and Complexity”. It is held by the Dept. of Applied Mathematics at RSPhysSE, ANU, and this year was organized by Dr. C. H. Arns. Despite the unseasonably cold weather (nightly temperatures approaching 5 degrees, daily maximum temperatures well below 20 degrees) it was a great success, with 60 scientists participating, among them 26 students and ECR’s. The participants came from 5 different Australian Universities, CSIRO, and 10 different countries. The aim of the workshop was to bring together researchers and students working across a wide range of topics from the forefront of materials science research, spanning several orders of magnitude in length scales and connecting the morphology of materials with their physical properties. The focus was on computational, theoretical, and experimental work that spans these fields. Conference topics included: • Networks and porous media • Theory and properties of crystalline frameworks • Granular matter • Soft matter and self assembly • Dynamic Surface Interactions and Surface Forces
The program followed an established and successful recipe to engage young scientists in discussions with their senior counterparts by having a good mix of overview talks given by senior scientists at the beginning of each session, followed by a series of presentations by students and ECR’s. The event was sponsored by the ARC Australian Advanced Materials network (ARNAM), the ARC Australian Nanotechnology Network (ARCNN), the Complex Open System Research
86 Network (COSNet), and the CRC Smartprint. This co-funded the costs of transport ($3550), all meals including conference dinner ($10,500), and accommodation ($3980).
The sponsorship of $4000 from the Australian Nanotechnology Network (ARCNN) allowed us to reduce the conference fees for ECRs and students. The conference fee included accommodation, all meals including the conference dinner, and transport to and from Canberra.

Report to the ARCNN: Conference on Optoelectronic and Microelectronic Materials and Devices (COMMAD) 2006 06/12/2006 – 08/12/2006 – The University of Western Australia
The COMMAD 2006 Conference was held at The University of Western Australia, Perth from 6-8 December 2006. The conference brought together world leaders and Australian ECR’s and postgraduate research students working in the area of optoelectronic and microelectronic materials and devices to discuss current and future research and industrial developments in these areas. There were 126 conference participants comprising both Australian and international participants. This was a truly international conference, and countries represented in the delegation included: Germany, Japan, China, USA, France, Norway, Italy, Canada, Sweden, UK, Turkey, Republic of Korea, Singapore, Iran, Taiwan, Hong Kong, India, Brazil, Malaysia, Slovenia, Czech Republic, Pakistan, and Bangladesh. One of the core objectives of the conference was to highlight the work of outstanding young Australian researchers who are making significant contributions in the areas of microelectronics, optoelectronics and micro-electro-mechanical systems (MEMS). These young researchers were financially supported by the ARCNN to make poster and oral presentations at the conference. The sponsorship of $10,000 provided by the ARC Nanotechnology Network was used to support 21 student and ECR registrations from Australia at $300 each, and 9 student and ECR travel subsidies at $200 each for non-Western Australian students from Swinburne Univ, ANU, Macquarie Univ, RMIT, UNSW, and U Melbourne. The remaining $2,000 was used to contribute to the 3 student prizes: 2 for Best Oral Presentation and 1 for Best Poster Presentation.

ARCNN Summer School: Modelling Molecular Material for Nanotechnology ARCNN Summer School Report “Modelling Molecular Materials for Nanotechnology” www.physics.uq.edu.au/cmp-workshop 10-15 December 2006 The University of Queensland’s Moreton Bay Research Station North Stradbroke Island The purpose of the “Foundations for Modelling Molecular Materials for Nanotechnology” Summer School was to give postgraduate students working at the interface of chemistry, physics, and materials science background knowledge that they would not have received because they had done a degree in chemistry or physics. It was also to break down some of the communication barriers between theoretical chemists and physicists. We are often working on similar problems from different angles and have our own terminology and focus.
15 PhD students, 8 postdoctoral researchers and 7 academics attended and lectured at the Summer School. These attendees were from The University of Queensland, The University of Sydney, The University of Melbourne, The University of Wollongong and Curtin University.
The funds obtained from the ARCNN paid for all lecturer/academic accommodation, meals and transport to and from the Island and also covered the same as scholarships for six students and four postdocs who were required to apply for the scholarships and undertake several eligibility requirements which included;

o Be a member of the ARCNN o Be a postgraduate student or early career researcher o Present a poster on their research project at the Summer School o Attempt at least half of the tutorial questions prior to the Summer School o Read all of the required reading before the Summer School o A commitment to make or update an entry on wikepedia on a subject relevant to the Summer School
The feedback at the end of the Summer School was very positive. Participants particularly enjoyed the interaction and format of the tutorials. A lot of people also expressed their interest in attending again this year.
The outcomes of the Summer School included • students getting a much stronger foundational knowledge • students of different backgrounds interacting with each other • a much greater understanding and communication between chemists and physicists interested in modelling molecular materials for nanotechnology.
