Groundbreaking Ceremony Held for New ECE Building by TOM MOONE
NEWS FOR ECE ILLINOIS ALUMNI AND FRIENDS WINTER 2011 Also in this issue: New Assured Cloud Computing Center to be established at Illinois Groundbreaking Solar Decathlon: Helping students and the world ceremony held Alumnus Michael McCorquodale is the first ECE Engineer for new ECE building in Residence Department of Electrical and Computer Engineering Breaking ground on the future Dear alumni and friends, I have good news! The dream of a new building for our department, after many years of planning and anticipation, is now becoming a reality. Last month’s groundbreaking of the new ECE building marks the beginning of a new era for our department, a department of global influence and impact, thanks to the excellence of its faculty and alumni. And it is this global impact that makes this groundbreaking special not only for our department, our college, our campus, and our university, but also for the state of Illinois, our nation, and the world. Our faculty and our alumni have been among the pioneers of the major technological innovations that are the bedrock of today’s computing and communication technologies. The marvel of the computing technology and the communications infrastructure we enjoy today, and its catalytic role in improving living standards around the globe, would not have been possible without John Bardeen’s invention of the transistor or Jack Kilby’s brilliant idea of the integrated circuit. These Nobel Prize-winning innovations by two giants of the ECE ILLINOIS community have been followed by many more groundbreaking advances by ECE faculty and alumni, advances that inspire and drive our quest for a sustainable future for all. -

(1) Chem Biochem, Florida State University, Tallahassee, Florida, United States (2) Center for Cancer Research, National Cancer Institute, , Frederick, Maryland, United States The remarkable progress made over the past two decades to grow inorganic nanomaterials, combined with careful surface functionalization strategies offer an opportunity to develop novel platforms for use in molecular imaging and as diagnostic tools. A successful integration into biological systems requires devising strategies to promote their intracellular uptake while circumventing endocytosis. We report on the use of an amphiphilic anti-microbial peptide as means of promoting the cytosolic uptake of luminescent QDs. The peptide is synthesized with a terminal cysteine to allow conjugation onto QDs that have been coated with multifunctional metal-coordinating ligands. Using fluorescence imaging and flow cytometry we find that incubating cells with the QD-peptide leads to delivery into the cytoplasm without affecting the cellular morphology or viability. We observed a homogeneous distribution of QD staining throughout the cytoplasm and without co-localization with labelled endosomes. Additional experiments where endocytosis has been eliminated (such as pre-treatment with specific inhibitors) have shown minimal effects on the intracellular QD uptake.

Designing a Nanoelectronic Circuit to Control a Millimeter-Scale Walking Robot
Designing a Nanoelectronic Circuit to Control a Millimeter-scale Walking Robot Alexander J. Gates November 2004 MP 04W0000312 McLean, Virginia Designing a Nanoelectronic Circuit to Control a Millimeter-scale Walking Robot Alexander J. Gates November 2004 MP 04W0000312 MITRE Nanosystems Group e-mail: [email protected] WWW: http://www.mitre.org/tech/nanotech Sponsor MITRE MSR Program Project No. 51MSR89G Dept. W809 Approved for public release; distribution unlimited. Copyright © 2004 by The MITRE Corporation. All rights reserved. Gates, Alexander Abstract A novel nanoelectronic digital logic circuit was designed to control a millimeter-scale walking robot using a nanowire circuit architecture. This nanoelectronic circuit has a number of benefits, including extremely small size and relatively low power consumption. These make it ideal for controlling microelectromechnical systems (MEMS), such as a millirobot. Simulations were performed using a SPICE circuit simulator, and unique device models were constructed in this research to assess the function and integrity of the nanoelectronic circuit’s output. It was determined that the output signals predicted for the nanocircuit by these simulations meet the requirements of the design, although there was a minor signal stability issue. A proposal is made to ameliorate this potential problem. Based on this proposal and the results of the simulations, the nanoelectronic circuit designed in this research could be used to begin to address the broader issue of further miniaturizing circuit-micromachine systems. i Gates, Alexander I. Introduction The purpose of this paper is to describe the novel nanoelectronic digital logic circuit shown in Figure 1, which has been designed by this author to control a millimeter-scale walking robot. -

The essence of nanotechnology is to produce and manipulate well- defined structures on the nanometer scale with high accuracy. Conventional technologies based on the "top-down” approaches, such as the photolithographyic method, are difficult to continue to scale down due to real physical limitations including size of atoms, wavelengths of radiation used for lithography, and interconnect schemes. -

Metal and Semiconductor Nanoparticle Self-Assembly
Metal and Semiconductor Nanoparticle Self-Assembly by G.

Kotov, Chair Professor Sharon C. Glotzer Professor Xiaoqing Pan Assistant Professor Suljo Linic © G. Daniel Lilly 2009 To my wife, Michelle M. Lilly, Ph.D. To my mother and father, Nancy N. and G. Bud Lilly ii ACKNOWLEDGEMENTS I would like to thank my loving and lovely wife Michelle for her support through the process of obtaining my Ph.D. If not for her support and advice I most likely would not have finished this process. I value her as a friend and partner and am forever appreciative of her actions. I would also like to thank my parents for laying the groundwork in my life to accomplish this. They taught me the value of hard work and persistence when reaching toward your goals, and without these lessons I most likely would not have even gone to graduate school, much less finished. I am appreciative for all the help and support my fellow lab members have given me over the last five years. Former lab members Jaebeom Lee, Zhiyong Tang, Paul Podsiadlo, Bongsup Ship, Jungwoo Lee and Kevin Critchley helped teach me new lab techniques, NP synthesis and conjugation techniques, and numerous analysis procedures, and allowed me a venue to discuss my hypotheses concerning these approaches. Current lab members Meghan Cuddihy, Edward Jan, Peter Ho, Ashish Agarwal, Christine Andres, Jian Zhu, Huanan Zhang, Elizabeth Stewart, Yichun Wang, Inigo Alvarez, Shimei Xu, and Anna Fernandez aided with various collaborations, techniques, procedures, and experiences for which I am grateful. -

Advisor: Marta Fernández Regúlez Christian Pinto Gómez Academic tutor: Joan Bausells Roigé i ii Abstract The main goal of this dissertation, entitled “Directed self-assembly of block copolymers for the fabrication of nanomechanical structures”, is to demonstrate the possibility of fabricating nanomechanical functional structures by employing the directed self- assembly (DSA) of block copolymers (BCPs) as a nanopatterning tool. DSA is a bottom-up nanolithography technique based on the ability of BCPs to segregate into domains at the micro/nanoscale, and it has attracted high interest due to its inherent simplicity, high throughput, low cost and potential for sub-10 nm resolution.
