Small Times: News About MEMS, Nanotechnology and Microsystems Small Times: News about MEMS, Nanotechnology and Microsystems 2171.090 -3.29 From the May/June 2006 issue of Small Times magazine 1272.980 + 0.11 A complete list of universities who participated in the survey and additional information about their micro and nanotech resources are included in the May/June 2006 issue of Small Times magazine. Highlights are included here. University at Albany-SUNY UAlbany's College of Nanoscale Science and Engineering (CNSE) has embarked on an ambitious program to make itself a leader in micro and nanotechnology education, research and development. With the state's blessing and strong support from industry, the young college has solidified its reputation as an applications-driven institution, particularly in the field of nanoelectronics. It also earned the top seed in Small Times' survey for education, facilities and industry outreach. The college built its program around four themes, a structure that it believes encourages cross-disciplinary education and research: nanoscience, nanoengineering, nanobioscience and nanoeconomics. Students choose from more than 60 courses to earn master's degrees and doctorates with concentrations in areas as varied as nanomaterials and modeling. The college is in the process of launching a bachelor's program in nanoengineering as well. The college introduced its Nano+MBA program in 2005, which allows students to wed their science and engineering education with business school savvy. The program's goal is to make graduates "industry-ready." Chances are good that students already have been exposed to industry's culture. The college is co-located with Albany NanoTech, a 450,000-square-foot complex that gives its 150 industrial partners access to laboratories, a supercomputer center and user facilities. The university places its assets at $3 billion, including cleanrooms with wafer processing capabilities. Albany NanoTech is expected to http://www.smalltimes.com/document_display.cfm?document_id=11552 Small Times: News about MEMS, Nanotechnology and Microsystems expand another 300,000 square feet. The region also houses numerous micro and nano-specific R&D centers, whose annual budget for fiscal year 2005 totaled almost $500 million. Most centers have ties to industry. IBM pledged $100 million in 2001 to support the Center for Excellence in Nanoelectronics, while the Center for Advanced Interconnect Science and Technology (CAIST) is funded by the Semiconductor Research Corp. CAIST is a consortium of 18 universities. Electronics giants such as IBM, Infineon, Honeywell and Tokyo Electron have partnered with the centers, generating more than $1.5 billion in revenue in 2005. The state has also been supportive. Most recently, it announced in early 2006 that it committed $80 million to the college for the Institute for Nanoelectronics Discovery and Exploration, a $435 million multi-university initiative that will be located on the Albany campus. While CNSE stands out for its work with industry, it has been less successful with pure research. As a young institution, the college appears to still be ramping up its faculty and research output. Cornell University Faculty and students at Cornell University were active in nanotechnology long before it became a buzzword. The university was among the first to customize facilities for the exacting challenges of working at the micron and nanoscale. Cornell's foresight from more than a decade ago has positioned it to compete with the best in nanotechnology today. Cornell maintains a diverse stable of research facilities that receive support from federal and state government agencies as well as some private funding. With an annual budget of more than $10 million in 2005, the Cornell Center for Materials Research has pulled together an interdisciplinary team of scientists and engineers in well-equipped shared facilities. The Nanobiotechnology Center brings in life scientists along with physical scientists and engineers to study biological systems at the subcellular and molecular level. The center has inspired researchers to develop novel micro and nanofabricated devices. http://www.smalltimes.com/document_display.cfm?document_id=11552 Small Times: News about MEMS, Nanotechnology and Microsystems The Center for Nanoscale Systems in Information Technologies focuses on the electronic, photonic and magnetic properties of nanomaterials. Its goal is to provide a new generation of products for computational, sensing, information storage and communications systems. Cornell is also one of only three universities worldwide selected by the philanthropic Kavli Institute to become a nanoscience research center. Cornell has been the most successful of the universities in its commercialization efforts, in part because the campus offers facilities for producing as well as studying at the micro and nanoscale. The Cornell NanoScale Science and Technology Facility makes its nanofabrication tools and processes and trained staff available to industry as well as university researchers. Almost half of its funding comes from user fees. Students and faculty also collaborate with corporations like IBM, Evident Technologies and Hitachi on projects as diverse as nanotransistors, quantum dots and memory devices. They're active with various national labs and institutes as well. The university stands out for its micro and nanotech patenting and creation of companies. The Cornell Center for Technology, Enterprise and Commercialization was consolidated in 2004 to support startups such as Illuminaria, whose portable biosensing technology was developed in the engineering department. University of Michigan Its engineering department is renowned for its work in microsystems. Its medical school cultivates doctors who understand not only patient physiology but the intricacies of nanoparticles. Its faculty members specialize in everything from computer simulations for modeling nanosystems to fabrication techniques for making MEMS devices. It's little wonder, then, that the University of Michigan ranked among the top 10 institutions for every key category in the survey. The university estimates that it has almost 100 faculty and 700 undergraduate and graduate students conducting research in micro and nanotechnology. Students can earn master's and doctorate level degrees in microsystems, or choose to minor in those subjects. Interdisciplinary class offerings cover the gamut, from biological http://www.smalltimes.com/document_display.cfm?document_id=11552 Small Times: News about MEMS, Nanotechnology and Microsystems micro/nanotechnology to nanophotonics to the societal impact of microsystems. Now in its sixth year, the National Science Foundation's Engineering Research Center for Wireless Integrated MicroSystems has demonstrated success with devices such as cochlear implants for the deaf and gas sensors for environmental monitoring. The engineering- based center has outreach programs involving eight other schools, and is incorporating more and more of the nanoscience advances under way at the university. The campus also houses the Michigan Nanofabrication Facility, which for a fee allows industrial, government and university researchers to use its equipment and processes. A $40 million expansion that will include 6-inch wafer capabilities and 4,000 square feet of cleanroom space is expected to be completed in 2007. The university is among a handful of research institutions that has successfully blended its medical and physical sciences. The Michigan Nanotechnology Institute for Medicine and Biological Sciences (M- NIMBS) focuses on medical uses of dendrimers and nanoemulsions. James Baker, a professor of internal medicine and director of M- NIMBS, has shown that dendrimers can be used for cancer drug delivery while nanoemulsions can serve in antimicrobial and vaccine applications. Rice University A lot of universities like to claim "firsts" in nanotechnology, but Rice University's status as one of the pioneers in nano research is hard to dispute. The university established its Center for Nanoscale Science and Engineering (CNSE) in 1996, the same year two of its faculty members received the Nobel Prize in chemistry for discovering buckminsterfullerenes. Buckyballs, as they're nicknamed, and their cousins carbon nanotubes have become popular in the study and commercialization of nanomaterials. And Rice has been leading the charge. The center now fits under the umbrella of the Richard E. Smalley Institute for Nanoscale Science and Technology. The name honors the late Richard Smalley, whose visions for near and future uses of nanotechnology helped persuade congressional leaders to provide billions of dollars to support nanoscience. Smalley shared the Nobel Prize with Rice's Robert Curl, and was the driving force behind the creation of CNSE. http://www.smalltimes.com/document_display.cfm?document_id=11552 Small Times: News about MEMS, Nanotechnology and Microsystems The institute's Center for Biological and Environmental Nanotechnology, one of the six inaugural National Science Foundation-supported nano centers, recently received a five-year renewal of its funding. That will allow the university to continue its work on environmental remediation as well as nanotech's possible adverse environmental and health effects. The institute also has targeted its researchtoward energy and health applications, and has rallied support and developed partnerships with industry, government agencies, research organizations and the State of Texas to accelerate nanotech innovation.

  • China's Progress in Semiconductor Manufacturing Equipment
    MARCH 2021 China’s Progress in Semiconductor Manufacturing Equipment Accelerants and Policy Implications CSET Policy Brief AUTHORS Will Hunt Saif M. Khan Dahlia Peterson Executive Summary China has a chip problem. It depends entirely on the United States and U.S. allies for access to advanced commercial semiconductors, which underpin all modern technologies, from smartphones to fighter jets to artificial intelligence. China’s current chip dependence allows the United States and its allies to control the export of advanced chips to Chinese state and private actors whose activities threaten human rights and international security. Chip dependence is also expensive: China currently depends on imports for most of the chips it consumes. China has therefore prioritized indigenizing advanced semiconductor manufacturing equipment (SME), which chip factories require to make leading-edge chips. But indigenizing advanced SME will be hard since Chinese firms have serious weaknesses in almost all SME sub-sectors, especially photolithography, metrology, and inspection. Meanwhile, the top global SME firms—based in the United States, Japan, and the Netherlands—enjoy wide moats of intellectual property and world- class teams of engineers, making it exceptionally difficult for newcomers to the SME industry to catch up to the leading edge. But for a country with China’s resources and political will, catching up in SME is not impossible. Whether China manages to close this gap will depend on its access to five technological accelerants: 1. Equipment components. Building advanced SME often requires access to a range of complex components, which SME firms often buy from third party suppliers and then assemble into finished SME.

    CHAPTER 11 Introduction The increase of world population is a challenge itself for world resources. The sustainability of food supplies, energy resources, and the environment are being questioned by analysts, while climate change just adds more pressure to the equation. The life expectancy of the world as a whole is rising while the fertility rate is declining. This will create a challenge in health care for the ageing population (Gavrilov and Heuveline, 2003). The United States alone will have 20% of the population over the age of 65 by 2050. In contrast, Europe will see rates close to 30% while Japan will arise to almost 40%, as summarized in Table 1.1. It is anticipated that in the near future, specialized health-care services will be in higher demand due to this increase. This demand will be characterized by medical resources not only to attend to this segment of the population, but also to keep them active as well. Therefore, the monitoring of physiological responses as well as specialized drug or other therapy delivery applications will be needed for portable, wearable, or implantable biomedical autonomous devices. In addition, wireless communication promises new medical applications such as the use of wireless body sensor networks for health monitoring (Jovanov et al., 2005; Hao and Foster, 2008; Varshney, 2007). These biomedical devices, however, come with their own issues, mainly power source challenges. Batteries are commonly used to energize most of these applications, but they have a finite lifetime.

Four ceramic nanoparticles, TiO2, SiO2, Al2O3, and maghemite (γ-Fe2O3) and ten substrate materials (Au, Al, Cr, Cu, Mo, Ni, Pt, SiO2, Al2O3, and SS304) were studied. The QCM technique was employed to measure frequency and motional resistance changes upon introduction of nanoparticles into the water surrounding its liquid-facing electrode. This series of experiments expanded prior studies that were often limited to a single nanoparticle - solid liquid combination. The variations in QCM response from one nanoparticle to another are observed to be far greater than the variation from one substrate to another, indicating that the nanoparticles play a larger role than the substrates in determining the frictional drag force levels.

  • Nanotribological Studies Using Nanoparticle Manipulation: Principles and Application to Structural Lubricity
    Friction 2(2): 114–139 (2014) ISSN 2223-7690 DOI 10.1007/s40544-014-0054-2 CN 10-1237/TH REVIEW ARTICLE Nanotribological studies using nanoparticle manipulation: Principles and application to structural lubricity Dirk DIETZEL1,*, Udo D. SCHWARZ2, André SCHIRMEISEN1 1 Institute of Applied Physics (IAP), Justus-Liebig-Universität Giessen, Germany 2 Departments of Mechanical Engineering & Materials Science and Chemical & Environmental Engineering and Center for Research on Structures and Phenomena (CRISP), Yale University, New Haven, CT, USA Received: 13 April 2014 / Accepted: 02 June 2014 © The author(s) 2014. This article is published with open access at Springerlink.com Abstract: The term “structural lubricity” denotes a fundamental concept where the friction between two atomically flat surfaces is reduced due to lattice mismatch at the interface. Under favorable circumstances, its effect may cause a contact to experience ultra-low friction, which is why it is also referred to as “superlubricity”. While the basic principle is intriguingly simple, the experimental analysis of structural lubricity has been challenging. One of the main reasons for this predicament is that the tool most frequently used in nanotribology, the friction force microscope, is not well suited to analyse the friction of extended nanocontacts. To overcome this deficiency, substantial efforts have been directed in recent years towards establishing nanoparticle manipulation techniques, where the friction of nanoparticles sliding on a substrate is measured, as an alternative approach to nanotribological research. By choosing appropriate nanoparticles and substrates, interfaces exhibiting the characteristics needed for the occurrence of structural lubricity can be created. As a consequence, nanoparticle manipulation experiments such as in this review represent a unique opportunity to study the physical conditions and processes necessary to establish structural lubricity, thereby opening a path to exploit this effect in technological applications.

The vacuum chamber of this 100 TeV, 100 km collider, will have to cope with unprecedented levels of synchrotron radiation linear power for proton colliders, 160 times higher than in the LHC for baseline parameters, releasing consequently much larger amounts of gas into the system. At the same time, it will be dealing with a tighter magnet aperture. In order to reach a good vacuum level, it has been necessary to find solutions beyond the particle colliders’ state of art. This paper proposes a design of a novel beam screen, the element responsible for absorbing the emitted power. It is intended to overcome the drawbacks derived from the stronger synchrotron radiation while allowing at the same time a good beam quality. DOI: 10.1103/PhysRevAccelBeams.23.033201 I.
