Announcements **************** 1.1: BNC All User Make Up Meetings: Wednesday, 03.28, 8:00am and Thursday, 8:00am, BRK 1001. Make up meetings are scheduled for BNC¹s once-per-semester all-user. If are a user of the cleanroom and/or laboratories, it is imperative that you attend a User Meeting. If you did not attend one of the earlier held meetings (March 19 or 20) and you do not attend one of these make up meetings, you will lose your access privileges. 1.2: Birck Annual Symposium of Research Programs: information update If available, please plan on attending the presentations describing projects, people, and capabilities enhanced by research performed in the Birck Center (MRGN 121; 3:00). Presenters include Profs. Rasid Bashir; Vlad Shalaev; David Janes; Ron Reifenberger, and Tim Fisher. Be sure that your poster has been hung in the building or is ready for display on an easel on Monday, April 2, 2007 by 2:00PM [TIME CHANGED]. For work that is complete, consider preparing it for hanging somewhere in the building (think about best location); if your work is in progress, we can still hang it but it might be best to present it on an easel. Both options are available. If you¹ve missed the powerpoint templates, let me know; I¹ll send them to you again. There are now several printed samples on display in the building; i.e., near the Surface Analysis Lab (across from the kitchen); upstairs as you enter from Bindley; downstairs near the AFM lab. Print your posters (FOR FREE!) in the Morgan Entrepreneur building (corner of State and Intramural; upstairs about halfway down the hall, on the left; I believe the room is 261) -- it¹s a computer lab; sign in with your ecn account and print from powerpoint (there are instructions there). Parijat Deb has printed there, you may ask him how easy it is. I¹m creating a ³brochure² for our event, please let me know the title and authors of your posters when possible. Poster session will run concurrently with the Discovery Park Advisory Council reception. Please be available at your poster to answer questions from 5:30 until 7:30 (dress: casual business). We will hold a reception for participants at 7:30 UPSTAIRS Atrium area. As this event is a ³dry run² for our first external advisory committee meeting (to be held next year at the time), we welcome all comments or suggestions. 1.3: HOLD THE DATE: Thursday, April 26, 11:00, MRGN 121, ³Microscale Platforms for Applications in Global Health Diagnostics,² by Dr. Bill Rodriguez, Assistant Professor of Medicine, Harvard Medical School. Of the 40 million people living with HIV infection worldwide, fewer than 10% are aware that they¹re infected. Fewer than 500,000 have access to the blood tests (CD4 cell counts and HIV RNA levels) essential for effective treatment. Of the 5,000 people dying each day from tuberculosis, half are undiagnosed; the best available test for diagnosing TB the light microscope was invented 350 years ago. Diagnostic tests for other major global diseases dengue, malaria, typhoid fever, diarrhea are equally unusable in resource-limited settings, like sub-Saharan Africa, where the global burden of disease rests. Can advances in microfabrication, microfluidics, MEMS, and biosensing be applied to the development of diagnostics for these diseases? Can they be made into truly point-of-care diagnostic products, against unforgiving specifications? We have applied these technologies to global health, and made progress in point-of-care devices for CD4 cell counting, HIV RNA measurement, and TB diagnosis. A review of the biological, technical, product development, intellectual property, funding, and commercialization challenges to unleashing the potential of bioengineering methods to have a major impact on global health will be presented. **************** 2.

Thermoelectricity is a type of solid state energy conversion process where the thermal gradient across a bulk material is used to generate electrical power. Thermoelectric devices are potentially applicable in multiple areas such as waste heat recovery systems for automobiles and power plants, steam-free powering of naval vessels, thermal management in integrated chips and terrestrial power generators employing concentrator solar cells. Although much work has been done on development of bulk and thin-film nanostructured thermoelectric materials, these material are not yet efficient enough to compete with conventional power generators. Recently, a different approach for thermal-to-electrical energy conversion was proposed that utilizes thermionic transport in metal-semiconductor multilayers or superlattices with nanoscale periods, unlike the diffusive transport in conventional thermoelectrics (Mahan et. al., PRL (1998), Shakouri et. al. APL (1997)). Subsequent theoretical work showed that cross-plane transport through such metal/semiconductor superlattices has the potential to yield values of the figure-of-merit that are much higher than those of currently available thermoelectric materials. The primary challenge involved in realizing a solid-state thermionic energy converter is selecting materials suitable for fabrication of stable superlattices with a high degree of crystalline order. The integration of materials with disparate electrical and physical properties in superlattices with nanoscale periods requires consideration of several aspects of materials compatibility, including a) the similarity in crystal structures and lattice parameters necessary to initiate and sustain superlattice growth, b) the thermodynamic stability of the constituent materials at high operating temperatures required for thermionic generators (hot side temperatures of 300 to 650°C), and c) comparable surface and interfacial energies to maintain a Frank-van der Merwe (i.e. layer-by-layer) growth mode. Considering all these constraints, we have identified TiN/GaN and ScN/ZrN as two potential material systems and in this presentation, I will discuss the suitability of these materials for thermionic energy converters. I will also present the preliminary structural, thermal and electrical measurements of these material systems. BIO: Vijay Rawat is a doctoral candidate in Materials Engineering at Purdue University and has been working with Prof. Tim Sands since 2004. He received his Bachelor of Technology in Metallurgical and Materials Engineering from Indian Institute of Technology, Kharagpur (India) in 2001, and his MS in Materials Engineering from Purdue University in 2003. 3.5: Friday, March 30, 10:30, BRK 2001: ³III/V Nanowires for Nanoelectronics,² by Werner Prost, University of Duisburg-Essen ABSTRACT: The vapor-liquid-solid growth mode provides high quality crystals wires at the diameter of the nanoscaled seed element. This approach offers the growth of highly mismatched materials due a gradual lattice constant matching of substrate to the wire material. This talk addresses promising combinations of III/V materials to standard substrates like GaAs, InP and Silicon. Moreover, both electronic and optoelectronic will be presented exhibiting already high performance, i.e. the transconductance of InAs FET in excess of 4 S/mm exceeds any other III/V or silicon based approach. Finally, the challenge of integration technologies for a future monolihtic implementation in large scale circuits will be addressed. BIO: Werner Prost is member of the technical staff at the University Duisburg-Essen. He received the PhD degree in electrical engineering from Duisburg University in 1989. His main interest is to contribute to the development of electronic- and optoelectronic devices at the nanoscale for communication technology by means of advanced heterostructure technology. He has (co-)authored more than 170 papers in scientific journals and conference proceedings. Prost is a member of the Center of Excellence SFB 445 ³Nanopartikels from the Gas phase² and of the Priority Program SPP 1165 ³Nanowires and Nanotubes,² the ³German Crystal Growth Association,² and an overseas member of the technical group on electron devices of the Japanese Institute of Electronics, Information and Communication Engineers. 3.6: Friday, March 30, 3:30pm, MSEE B012: ³Interface Properties from Their Equilibrium Fluctuations,² by Moneesh Upmanyu, Colorado School of Mines ABSTRACT: Thermodynamic and kinetic properties of interfaces play a central role in the interplay between growth and form of interfacial microstructures. Due to the limitations associated with accessible spatio-temporal scales in experiments and also in atomic-scale simulations, extracting these properties has been challenging. In this talk, I will present our recent work on theoretical frameworks and associated computational techniques aimed at extracting equilibrium interface properties, mainly their mobility and stiffness, from their fluctuations. The generality of this technique combined with inherent spatio-temporal efficiency permits extraction of interface properties in wide range of material systems. As validation, I will present results on homophase interfaces, or grain boundaries in pure aluminum. The misorientation and temperature dependence properties indicate a structural coupling between these properties that sets the overall anisotropy of the grain boundary properties. Extension of the techniques to include the effect of impurities provides for the first time a direct measure of the impurity drag effect. Ongoing theoretical analyses will be presented, which require extension of classical Brownian motion of particles to that in a binary medium. Implications for microstructural evolution during annealing phenomena will be discussed. BIO: Dr. Moneesh Upmanyu was born in Bombay, India, and received his B. Tech. degree in Metallurgical Engineering and Materials Science from the Indian Institute of Technology, Bombay, in 1995, and Ph.D. degree in Material Science & Engineering with a minor focus in Computational Materials Science from the University of Michigan in 2001. He was also a visiting Graduate Student and then a Postdoctoral Research Fellow in the Mechanical and Aerospace Engineering Department and (then) Princeton Materials Institute at Princeton University. Following that, he spent a year as a Postdoctoral Research Scientist in the Computational Materials Science Division at Oak Ridge National Laboratory before accepting a position as an Assistant Professor in the Engineering Division and the Materials Science Program at Colorado School of Mines in Fall 2002. He heads the Group for Simulation and Theory of Atomic-scale Material Phenomena (stamp) and is now also affiliated with the Bioengineering and Life Sciences Program within the Engineering Division. Dr. Upmanyu¹s research is aimed at exploring atomic-scale phenomena using computational techniques and theoretical frameworks in several classes of material systems, both in nature and technology. His interests range from interfacial phenomena in polycrystalline microstructures, structure-morphology-property relations in thin films and wires, and atomistics, mechanics & self-assembly of semi-flexible filamentous aggregates as well as their networks in biology and technology. Targeted material systems include grain boundary microstructures in crystalline materials, metallic and semiconducting thin films, inorganic nanowires, nanotubes and their assemblies, and soft filamentous assemblies such as DNA, twisted protein aggregates, and their networks. His group¹s principal expertise is in computational techniques such as molecular dynamics and Monte-Carlo based methods and their links with continuum methods such as phase field and finite-element methods as well as meso-/continuum theoretical frameworks. Dr. Upmanyu is the recipient of several awards including the Graduate Student Medal (Materials Research Society) and the Outstanding Young Scientist Award (Recrystallization & Grain Growth Congress). He is a member of the Materials Research Society (MRS), The Minerals, Metals and Materials Society (TMS), The American Physical Society (APS), The American Society for Metals (ASM) and Society for Industrial and Applied Mathematics (SIAM). ************************ 4.

THURSDAY, MARCH 22, 10:30 AM BRK 1001: ³High-Aspect-Ratio Micromachining of Titanium: Enabling New Functionality and Opportunity in Micromechanical Systems Through Greater Materials Selection² Dr. Masa P. Rao, Assistant Professor School of Mechanical Engineering, School of Materials Engineering (by courtesy) Birck Nanotechnology Center - Center for Advanced Manufacturing Traditionally, materials selection has been limited in high-aspect- ratio micromechanical applications, due primarily to the predominance of microfabrication processes and infrastructure dedicated to silicon. While silicon has proven to be an excellent material for many of these applications, no one material can meet the needs of all applications. This is especially evident in biomedical microdevice applications, where the intrinsic brittleness of silicon limits its utility, thus illustrating the need for development of viable alternatives. Titanium is particularly promising in this regard, due to its toughness, biocompatibility, and fatigue resistance. However, lack of sufficient fabrication capability has limited its use in micromechanical systems thus far. Recently, we reported the development of novel micromachining processes that now enable realization of this promise. These processes, based on plasma etching techniques derived from microelectronics manufacturing, provide for the first time, the capability for fabrication of complex, micrometer-scale, high-aspect- ratio structures in titanium. As such, these processes not only extend the state of the art in titanium micromachining, but also do so in a manner amenable to scaling to low-cost/high-volume manufacturing, due to the economy of scale inherent to the batch- processing paradigm of the microelectronics industry. The focus of this talk will be to detail these processes, their capabilities, and their use in the fabrication of micromechanical devices for optical, RF, and biomedical applications. Prof. Rao received his bachelors in Materials Science and Engineering from the University of Florida and his Ph.D. in Materials Engineering from the University of California, Santa Barbara (UCSB). Following graduation, he accepted a position as a post-doctoral researcher in the Mechanical Engineering Department at UCSB, where he was involved in the initial development of plasma-based micromachining of titanium. He joined the School of Mechanical Engineering at Purdue University as a Assistant Professor in January 2007. Prof. Rao¹s current research interests lie in the continued development of titanium micromachining and its application towards biomedical microdevices, as well as the development of other novel microfabrication technologies for various applications. He has authored/co-authored over 15 journal articles and conference proceedings, and has presented lectures in fields ranging from ceramic composites for gas turbine applications to MicroElectroMechanical Systems (MEMS) for telecommunications and biomedical applications. ********** FRIDAY, MACH 23, 1:30 PM BRK 1001: "Planning for Disaster: Designing a Cleanroom to Minimize Risk Should a Disaster Occur" John Weaver Purdue University The cleanliness levels of a cleanroom or other high-technology facility make it inherently vulnerable to a disaster such as a fire. Historically, even a small event of this type can cause significant downtime and cost millions of dollars in remediation. When designing a cleanroom, steps can be taken to minimize the impact of a disaster and to enhance the recovery process. This paper reviews various potential scenarios and decision points in the design process that are relevant to those situations. It then outlines the decisions made in the design of a recent nanofabrication research facility, the Birck Nanotechnology Center at Purdue University. John Weaver serves as the Facility Manager for the Birck Nanotechnology Center at Purdue University. He is responsible for the facility infrastructure, safety and training activities, and cleanroom and laboratory operations. John received his BS degree in Chemistry at Adrian College in 1972, and joined RCA Solid State Division in process engineering in the world¹s first production CMOS fabrication facility. In 1975 he moved to Hughes Aircraft Company¹s Solid State Products Division in Newport Beach, California, where he continued his role in high-volume manufacturing-support engineering. In 1977, he moved to what is now Delphi Corporation in Kokomo, Indiana. During his career, John has been involved in a variety of roles in semiconductor process support, process development, and processing facilities development. John has published numerous papers in both the process development and contamination control fields, has two patents in process development, and authored a book and a book chapter in contamination control technology. He has taught a wide variety of industry short-courses, and is the recipient of the Willis J. Whitfield Award for contributions to the field of contamination control. He is a Senior Member of the Institute for Environmental Sciences and Technology, President of the Indiana Chapter, member of the Editorial Board for the Journal of the IEST, and is a Principal Member of the NFPA 318 committee, which writes fire standards for cleanrooms. He has been involved in the design, construction, and/or operation of more than 25 cleanrooms and clean facilities during his career. ****************************** SPONSORED BY: Birck Nanotechnology Center, Bindley Bioscience Center, Discovery Park, The NASA Institute for Nanoelectronics and Computing, The Network for Computational Nanotechnology, VEECO, NCN Student Leadership Council, Department of Chemistry, Department of Physics, School of Chemical Engineering, School of Electrical and Computer Engineering, School of Mechanical Engineering
