06 Dec '07

Deborah, Can you please forward this email as well as add it to the Monday Memo? This pertains to proposals and using Grants.gov. Thanks, Stacy Stacy Brown Purdue University Business Manager Birck Nanotechnology Center Phone: 765-494-1619 Fax: 765-496-8299 -----Original Message----- From: ba-l-bounces(a)lists.purdue.edu [mailto:ba-l-bounces@lists.purdue.edu] On Behalf Of Dimmitt, Robert J Sent: Wednesday, December 05, 2007 7:51 PM To: bacl-l(a)purdue.edu; ba-l(a)purdue.edu Subject: Grants.gov adobe forms - PLEASE CIRCULATE PLEASE FORWARD TO ALL FACULTY AND STAFF AS NECESSARY. During September of this year, grants.gov underwent a major change by starting to migrate proposal packages from the puredge forms to adobe pdf forms. One of the biggest benefits of this change is that it will allow us the ability to have a platform independent submission tool. The adobe forms can be used on both mac and pc without any special software or additional steps. A couple of very important things to remember: - MOST IMPORTANT - when filling out the new forms, the packages should be built and submitted using either adobe reader or acrobat 7.0.9 or 8.1.1. Any version used outside of the two approved versions will not be supported by grants.gov and will result in errors not allowing the package to be submitted. REMEMBER - ALL ACTIVITY IN CREATING AND SUBMITTING THE PACKAGE MUST BE COMPLETED USING EITHER 7.0.9 OR 8.1.1. - Free downloads of adobe 7.0.9 and 8.1.1 can be found at http://www.grants.gov/resources/download_software.jsp. - Pdf packages can be built and completed using the free adobe reader software. There is no need to purchase the adobe acrobat software. - The transition to adobe forms is being phased in over time. Until the transition is complete, there will be a need to maintain the puredge software on your computer in the event that you are submitting a puredge (.xfd) package. Additionally, attached to this message, is an excel spreadsheet that can be used as a reference tool when trying to determine what computers and operating systems are compatible with the different grants.gov submission tools. If you have any questions, please feel free to give me a call.

Seminars **************** 2.1: Monday, December 3, 2007, 2:30PM, POTR 234 Fu Room: ³Lectures on molecular dynamics modeling of materials,² by Alejandro Strachan ABSTRACT: Molecular dynamics simulations are playing an increasingly important role in many areas of science and engineering, from biology and pharmacy to nanoelectronics and structural materials. Recent breakthroughs in methodologies and in first principles-based interatomic potentials significantly increased the range of applicability of MD and the accuracy of its predictions even for new materials not yet fabricated or synthesized. Such predictive power indicates that MD has the potential to play a key role in guiding the design and optimization of new materials with improved properties tailored for specific applications. The goal of this short course is to provide an introduction to the theory behind MD simulations, describe some of the most exciting recent developments in the field and exemplify its use in various applications. The short course consists of a brief introduction and three lectures: Introduction: molecular dynamics simulations. This short presentation will describe the idea behind MD simulations and demonstrate its use in real applications. Lecture 1: the theory behind molecular dynamics. The first lecture will provide a brief description of classical mechanics and statistical mechanics necessary to understand the physics and approximations behind MD and how to correctly interpret and analyze its results. The power, range of applicability and limitations of MD will be discussed. Lecture 2: interatomic potentials. I will describe the various models used to describe the interactions between atoms in a wide range of materials including metals, ceramics and soft materials as well as new recent advances like reactive force fields. The key physics of widely used force fields will be described as well as their accuracy. Lecture 3: simulation details and coarse grain approaches. The last presentation will describe simulation techniques to simulate materials under isothermal and isobaric conditions. We will also describe coarse grain or mesodynamical approaches (where mesoparticles describe groups of atoms) focusing on recent advances in theory that enable thermodynamically accurate simulations including the description of quantum effects in the thermal properties of high-frequency vibrational modes. The lectures will be complemented with hands-on exercises utilizing the nanoMATERIALS simulation toolkit at the nanoHUB that enables running MD simulations simply using a webbrowser. BIO: Alejandro Strachan is an Assistant Professor of Materials Engineering at Purdue University. He received his doctoral degree in Physics from the University of Buenos Aires, Argentina. Before joining Purdue, Professor Strachan was a staff member in the Theoretical Division of Los Alamos National Laboratory and worked at the California Institute of Technology. Prof. Strachan¹s research focuses on developing and validating atomic and mesoscale computational methodologies aimed at predicting the behavior of materials from first principles and their application in technologically relevant areas where a molecularlevel understanding can help solve outstanding problems. Areas of interest include: nanoscale and nanostructured materials for electronics and electro-mechanical systems, active and energetic materials, mechanical properties of molecular solids, and computational materials design. 2.2: Tuesday, December 4, 10:00AM, BRK 1001: ³Nano-materials for Nano-electronics,² by Dr. Zhihong Chen, Research Staff Member, IBM Research Division ABSTRACT: With current nano-electronics approaching its scaling limit, a new emphasis has been placed on looking for new materials that can provide better electronic properties than silicon. It is extremely important to develop a thorough understanding of these new materials and take advantages of them in device designs. In my presentation, I will discuss two nano-materials carbon nanotube and graphene. Carbon nanotubes have been shown to have outstanding electronic properties mainly owing to their dimensionality. I will present fabrication and measurement of a gate-all-around carbon nanotube transistor an ultimate device design which takes advantage of the smallness of this material. Challenges in material complexity and device fabrication will be discussed and an outlook on nanotube based technology will be presented. Graphene has been a rapid rising star in the scientific community in the past two years. As the basic building block for carbon nanotubes, graphene shares many common physical properties and is attractive for electronic applications because of the possibility of large scale film growth and implementation. I will demonstrate devices fabricated with single or double layer graphene and discuss our current understanding and the required studies planned for the future to achieve better device performance in future nano-electronic applications. Zhihong Chen received her B.S. degree in physics from Fudan University, Shanghai, China, in 1998, and her M.S. and Ph.D. degree in physics from the University of Florida in 2002 and 2003, respectively. Her Ph.D thesis work involved studies of the physical and chemical properties of carbon nanotubes. She co-invented a method to assemble nanotubes into ultra-thin, conductive and highly uniform films, which can be used as transparent electrodes in many applications. Her research on separation of carbon nanotubes by electronic types was targeting the most challenging problem in the field and was one of the first few attempts, which have been extensively followed up. Dr. Chen has joined the IBM T.J. Watson research center in 2004, where she is currently is a research staff member in the Physical Science Department. Her research at IBM focuses on exploring new materials for nano-electronics. Her contributions include a thorough exploration of material choices for high-performance nanotube transistors, demonstration of a process flow for integrated nanotube circuits, and studies of fundamental properties of new materials such as graphene for electronic applications. 2.3: Thursday, December 6, 4:00PM refreshments, ME 256; seminar, 4:30PM, ME 161: ³Miniaturized Processes and Machines for Micro-cutting and manipulation,² by Kornel F. Ehmann, James N. and Nancy J. Farley Professor in Manufacturing and Entrepreneurship, Northwestern University ABSTRACT: The miniaturization of components and products increasingly requires the manufacture of micro/meso-scale features in the range of a few microns to a few millimeters on components whose size does not exceed several millimeters. Yet, in spite of the perceived similarity between conventional and micro/meso-scale manufacturing the physical mechanisms that govern the latter processes are vastly different and so are the characteristics of the machines and systems that are needed for their execution. In regard to the machines and systems there is ample of evidence to suggest that downscaled processes and machines exhibit superior capabilities. In this presentation a few key aspects of process and machine miniaturization will be addressed on two representative examples. The first is the development of miniaturized machine tools and their key component, an ultra-high speed spindle, for micro-cutting operations in conjunction with the analysis and modeling of dynamic instabilities in these operations. The second is a comprehensive discussion of the feasibility of developing monolithic mechanisms for micro/meso-scale part manipulation. The specific example will focus on a shape memory alloy based manipulator. Issues to be discussed include the manufacture of the mechanism, the feasibility of ³self-sensing² and the modeling of the transformation kinetics and dynamics of the device. BIO: Kornel F. Ehmann is the James N. and Nancy J. Farley Professor in Manufacturing and Entrepreneurship of the Mechanical Engineering Department at Northwestern University.

Examples include: Tracking of thousands of fuel droplets in a locally isotropic turbulent flow enables measurement of their turbulent diffusion coefficient as a function of turbulence level and droplet properties; Studying the near-wall flow within a turbulent boundary layer over a smooth wall, while fully resolving the viscous sublayer, buffer layer and lower portion of logarithmic layer. Resolution is sufficient for measuring the instantaneous wall shear stress distributions from velocity gradients in the viscous sublayer. Conditional sampling based on local shear stress magnitude identifies characteristic 3-D flow structures that generate extreme wall stress events; Measuring the flow generated by swimming of a copepod, a mm size marine organism, and its effect on its swimming behavior. A recirculating flow pattern in the copepod¹s frame of reference is caused by the combined effects of sinking and a propulsive force generated by the feeding appendages. The low Reynolds numbers associated with motion of 0.1 mm naupleus, a baby copepod, cause it to recoil as it brings its swimming appendages forward to propel itself; Characteristics of the generally helical but complex swimming of 10-30 mm dinoflagellates change dramatically with introduction of prey into the sample volume, demonstrating different predation strategies. The presentation will conclude with introduction of a submersible, free drifting oceanic holography system. Data from recent deployments display behavior of and interactions among several organisms, such as a dinofalgellate escaping from a naupleus, and clouds of particles around swimming Appendictularians. JOSEPH KATZ received a B.S degree from Tel Aviv University and M.S and PhD from the California Institute of Technology, all in Mechanical Engineering.

However, despite extensive research in biosensors and their enormous potential compared to laboratory-based analytical techniques, the biosensor market is relatively small and numerous problems still remain to be solved. This presentation will discuss new ways of designing biosensors with improved selectivity and lower detection limits. Novel materials and advanced immobilization methods capable of depositing biologically active material, particularly enzymes, onto or in close proximity of the transducer surface and applications of these devices for the detection of clinically and environmental important analytes will be presented. Problems associated with a direct detection of hydrogen peroxide, enzyme stability, interferences and overlapping signals in clinical samples will also be addressed. BIO: Dr. Silvana Andreescu received her PhD in 2002 in Agrochemistry from the University of Perpignan, France and in Analytical Chemistry from the University of Bucharest, Romania. In the same year she was awarded a NATO-NSF postdoctoral fellowship award when she joined the Department of Chemistry, State University of New York at Binghamton as a postdoctoral fellow. Since 2005, she is an assistant professor at Clarkson University, Potsdam, NY. Her main research interests include the development of biosensors for monitoring different analytes of interest in clinical, food quality and environmental control. Other interests include development of multifunctional biocapsules for use in alternative energy production and bioremediation. 2.10: Friday, November 30, 10:30AM, LILY 1-117, Biophysics Seminar: ³Mapping protein folding landscapes,² by Harry B.

This year marks the 60th anniversary for the Toys for Tots tradition of the US Marine Corps Reserves. In 2006, Toys for Tots delivered more than 19.2 million toys to over 7.6 million children. Unfortunately, with over 13 million children living in poverty, Toys for Tots needs your help more than ever to achieve the goal of delivering a toy to every child in need. Deborah S.
