Seminar Announcements ************************ 3.1: ³Engineered Drug Therapies Enabled by Fabrication Processes from the Electronics Industry,² by Joseph M. DeSimone, Departments of Chemistry & Pharmacology, University of North Carolina at Chapel Hill; Department of Chemical Engineering, North Carolina State University; MARCH 6, 2007, 4:30-5:30, WTHR 104. A novel method for the fabrication of organic particles on the order of tens of nanometers to several microns will be described. Our imprint lithographic technique called PRINT (Practicle Recplication In Non-wetting Templates), takes advantage of the unique properties of elastomeric molds comprised of a low surface energy perfluoropolyether network, allowing the production of monodisperse, shape-specific nanoparticles from an extensive array of organic precursors. This engineered nature of particle production has a number of advantages over the construction of traditional nanoparticles such as liposomes, dendrimers, and colloidal precipitates. The nature of PRINT technology takes drug delivery for the first time into the uncharted realm of engineered drug therapies given its á la carte approach and versatility. PRINT allows for the precise control over particle size (20 nm to >100 micron), particle shape (speres, cylinders, discs, toroidal), particle composition (organic/inorganic, solid/porous), particle cargo (hydrophilic or hydrophobic thereapeutics, biologicals, proteins, oligonucleotides, siRNA, imaging agents such as MR contrast agents, positron emitters), particle modulus (stiff, deformable) and particle surface properties (Avidin/biotin complexes, targeting peptides, antibodies, aptamers, cationic/anion charges, Stealth PEG chains). I believe that PRINT is the only technology that can independently design these attributes to create truly engineered drug therapies. For the first time, key therapeutic parameters such as bioavailability, biodistribution, and target-specific cell penetration should be able to be simultaneously designed into a therapy. Preliminary in vitro and in vivo studies have been conduced, demonstrating the future utility of PRINT particles as delivery vectors in nanomedicine. 3.2: ³Mechanisms of Cancer Chemoprevention: Studies with Green & Black Tea,² by James Klaunig, Indiana U School of Medicine, MARCH 6, 1:30-2:30 pm, MRGN 121. Reception immediately following in MRGN Café. ABSRACT: Chemoprevention involves the intervention during the early stages of the cancer process resulting in either modification of the uptake, or excretion, modification of the metabolism, enhancement of cellular repair mechanisms, or induction of apoptotic effects selectively to preneoplastic or neoplastic cells. Cancer chemoprevention differs from the chemotherapy in that it works on the initiation and promotion stage of the multi-stage cancer process. Multiple chemo-preventive agents have been identified. These include both natural as well as synthetic products, functioning include modulation of receptors in particular hormone receptors, inducers or inhibitors of metabolism of carcinogens, and antioxidant materials. Of the antioxidants; teas, vitamin E and glutathione have been the subject of extensive investigation both experimentally and epidemiologically. Studies examining the mechanisms of action of these antioxidants will be discussed. 3.3: ³Essentials of Visualization,² by David Ebert, Professor, School of Electrical and Computer Engineering, Director, Regional Visualization and Analytics Center, Purdue University; MARCH 7, 2:00-3:00, EE 317. ABSTRACT: In this talk, the basic techniques for visualization, some of the tools available, and how to NOT miscommunicate information from your visualizations will be covered. BIO: David Ebert is a Professor in the School of Electrical and Computer Engineering at Purdue University and directs the Purdue University Regional Visualization and Analytics Center.

Bring your lunch. This talk is one of Regenstrief Center¹s Brown Bag seminars in which a variety of Purdue healthcare researchers and Regenstrief Center partners presents lectures geared toward graduate students interested in healthcare. 3.5: ³Advances in High-Frequency Applied Electromagnetic Applications,² by William Chappell, Professor of Electrical Engineering, Purdue University; MARCH 9, 3:30-4:30 pm, MSEE B012. Refreshments served. ABSTRACT: This talk will cover the recent advancements in the field of microwave and millimeter wave Systems-in-a-package and more generally applied electro-magnetics. A brief overview of the type of wireless circuit ³front ends² that are of interest will be presented and the relevance of the research ongoing by the new faculty in this area will be discussed. Specifically of interest to the ceramic packaging community are the so-called metamaterials. This class of materials is loosely defined as the creation of behavior not found in nature by the small scale ordering within the material. Periodic and self-aligned materials will be presented. In our specific appli-cation, we utilize multilayer and ceramic free form fabrication techniques to create periodic low loss materials for micro and millimeter wave substrates. The 3-dimen-sional fabrication techniques and the material characterization will be discussed. The creation of utilization of these materials in filter and antenna applications will be discussed and their ramifications analyzed. In addition, new three-dimensional packaging concepts will be introduced. SHORT BIO: William Chappell is an Assistant Professor of Electrical and Computer Engineering at Purdue University.

Seminar Announcements ************************ 3.1: Wednesday, 02.28, 2:00 PM, EE 317 ³Nanolithography,² by Minghao Qi, Purdue University ABSTRACT: Integrated circuits have dramatically changed the way people live, communicate and work over the past forty years. For example, digital storage has almost eliminated the need for printed materials as a method of preserving information. However, another means of printing, or lithography, has been the driving force for the ever faster, cheaper, yet more powerful computer chips. Lithography is probably the most important process in transforming human creativity and engineering efforts into real devices or systems. This tutorial will go through pattern generation and duplication, as well as resist technology. Both fundamental laws governing the resolution and throughput of lithography and latest trends in state-of-the-art lithography will be discussed. At the nanometer length scale, lithography continues to play a central role in prototyping novel devices, and will meet in the near future the bottom-up approach, which generates patterns by controlled chemical growth/synthesis. NOTE: This seminar is being taped for the nanoHUB¹s Nanotechnology 501 Seminar Series at http://www.nanohub.org/education/nanotechnology501 <http://www.nanohub.org/education/nanotechnology501> ABSTRACT: Minghao Qi received his BS degree in Chemical Physics from the U of Science and Technology of China in 1995. He received his MS and PhD in Electrical Engineering from Massachusetts Institute of Technology in 1998 and 2005 respectively. He was a post-doctoral research associate in the Research Laboratory of Electronics at MIT before joining Purdue University as an assistant professor of Electrical and Computer Engineering in August 2005. 3.2: Thursday, 03.01, 10:30 AM, BRK 1001 ³Computer Simulation of Nanoparticles, Viruses, and Electrical Power-Generating Bacteria,² by Peter Ortoleva, Indiana University ABSTRACT: Models of cells and nanometer-scale biosystems are presented that clarify their physico-chemical characteristics and allow for computer-aided design of therapeutic and nanotechnical devices. Multiscale techniques are used to obtain rigorous, coarse-grained equations for the migration and structural transitions of viruses and other bionanostructures. The theory starts with the N-atom Liouville equation and arrives at Langevin equations for the fluctuating dynamics of order parameters characterizing the state of major nanoscale components (e.g., protomers, pentamers, and hexamers for viral capsids). Application of the theory to macromolecules is also illustrated. A phenomenological approach is used to analyze electrical power generating bacteria. A microbial fuel cell is described in terms of a circuit diagram accounting for nanowires. These wires are self-assembled by the bacterium to mediate electron transfer processes. When the bacteria, electrodes, and substrate-bearing fluids are correctly configured, the system constitutes a bacterial fuel cell capable of directly converting organic waste into electrical power. BIO: Peter J. Ortoleva is a Distinguished Professor and Director of the Indiana University Center for Cell and Virus Theory in the Department of Chemistry. He received his PhD in Applied Physics at Cornell U, was a Postdoc in the Dept of Chemistry at MIT, and joined the faculty of the Dept of Chemistry at Indiana U in 1975. He has published over 187 refereed papers, 3 monographs, and 3 edited volumes. His research interests include: the theory of reaction-transport mechanical systems; chemical kinetic; statistical mechanics; cell and virus modeling; regulatory network discovery; and nonlinear dynamical systems theory.

However, the current semiconductor technologies available essentially involve merging of chips fabricated with standard CMOS technology. These CMOS compatible technologies provide an integration solution with compatible fabrication processes that require little changes in process integration. Even with some limited product offerings such as integrated accelerometers and pressure sensors, it remains a challenge to merge devices from non-compatible fabrication processes in a cost-effective way. Nanotechnology, enabled by Micro-Electro Mechanical Systems (MEMS), may offer a solution by making inexpensive LEGO-like building blocks to snap together a system. MEMS-enabled nanotechnology applies the tools and processes of nano/microfabrication, compatible or non-compatible with CMOS, to build devices and systems. This presentation will be focusing on the current topics in the development of nanotechnology and MEMS technology. After a brief overview of the College of Nanoscale Science and Engineering at University at Albany/SUNY, a few project examples will be used to introduce our MEMS program. MEMS provide important tools to address the bottlenecks in realizing Feynman's vision of nanotechnology: the fusion of Nanotech, Biotech and Infotech, which is a growing area of scientific and technological opportunities. BIO: Prof. Bai Xu obtained his PhD in Material Sciences from U of Paris/CNRS in 1991. He is currently an Assistant Professor of SUNY at Albany and Senior Research Scientist of Albany NanoTech. Prof. Xu manages the MEMS program at Albany NanoTech, which has a technology portfolio of optical MEMS, bioMEMS, fluidic MEMS and RF MEMS. Before joining Albany NanoTech, Prof. Xu worked at IME Singapore and I-STAT Canada where he initiated a number of MEMS development projects that led to the fabrication of MEMS micro-relays, MEMS microphone, pressure sensors, flow sensors, accelerometers and miniaturized biomedical testing devices. Prof. Xu has been very active in the MEMS and Nanotechnology area. He served on the review panel of the National Science Foundation to review the Nanotechnology Interdisciplinary Research Team Proposals. He was the Chair of the Special Symposium for Science and Fabrication of Nanosystems sponsored by the Upper State New York Chapter of the American Vacuum Society.

Though adhering only to the simple¹ principles of attaining and maintaining liquid metal integrity through avoidance of free surface turbulence during metal movement, the process poses significant challenges when operated at an industrial scale. This seminar will review free surface turbulence as a mechanism for formation of oxide bifilms and their impact on casting reliability, describe the high volume Cosworth casting process and present results of a recent benchmarking exercise of European premium automotive foundries. BIO: Nick Green holds the EPSRC/Rolls-Royce Star Appointment in Casting Technology and has worked in casting research since completing his PhD (Cambridge 1992), beginning his postdoctoral career at Birmingham. He then moved into the automotive foundry industry. Throughout his career he has pursued his interest in relationships between casting processes and casting reliability, applying root cause understanding of defect forming mechanisms to casting process development for improved reliability, process simplification and scrap reduction. Prior to his appointment he worked for eight years in the automotive foundry industry, most recently as Technical Director of Cosworth Technology Ltd (20002005), developing innovative solutions for improved material and engine performance in high volume, niche and racing applications. Recent research led to two patent applications in the areas of enhanced integrity/fatigue life and enhanced dimensional accuracy. From 1996 to 2000 he was Technical Manager of VAW motorcast Ltd, a major UK automotive foundry manufacturing approximately 1.51.8 million cylinder heads and engine blocks per annum. During this period he was also Competence Leader for Process Development within VAW¹s group of European foundries. In 19981999 he directed the technical launch of a major green field joint venture in Mexico (Castech SA de CV) to produce aluminum cylinder heads and blocks for the North American market. In 2000 he was awarded the American Foundrymen¹s Society (AFS) Howard F Taylor Award and received their best paper award in both 1998 and 1994.

The first talk in this semester's CCAM seminar series
by Jie Shen 26 Feb '07

26 Feb '07

CCAM Seminar Series on "Mathematics and Numerics of Fluid Dynamics with an Emphasis on Complex Fluids" Title: Simulation of Complex Fluids using Dissipative Particle Dynamics Speaker: Professor George Karniadakis, Brown University Time and place: Friday March 2, 3:30pm at UNIV 103 Abstract: Dissipative Particle Dynamics (DPD) is a relatively new mesoscopic method particularly suitable for simulating biopolymers. It is a coarsed grained molecular dynamics method and exhibits both thermal fluctuations but also hydrodynamics behavior. In this presentation, I will review some of the recent advances but also the limitations due to boundary conditions and extreme coarse graining. Examples will be given for DNA dynamics in nanochannels and modeling of red blood cells at the nanometer scale. ------------------------------------- -- **************************************************************** Professor http://www.math.purdue.edu/~shen Department of Mathematics tel: 1-765-494-1923 Purdue University fax: 1-765-494-0548 West Lafayette, IN 47907 e-mail: shen(a)math.purdue.edu ***************************************************************

Nano Seminar: Dr. Samir Iqbal, Purdue, Thurs., 2/22/07, @ 10:30 AM, BRK 1001 (On the Cross Roads of Biology and Nanotechnology Selective DNA Nanopore Sensors
by Deborah Starewich 21 Feb '07

Late announced seminar . . . Didn't make the Monday memo so I am sending an additional e-mail ³On the Cross Roads of Biology and Nanotechnology Selective DNA Nanopore Sensors² Thursday, February 22, 2007 Birck Nanotechnology Building, Room 1001 10:30 AM Dr. Samir Iqbal Purdue University The ability to manipulate and identify the properties of single biological molecules with the potential of characterizing biological processes at the most fundamental levels can significantly facilitate rapid diagnostics and therapeutics. Fabrication of solid-state devices investigating bacteria, viruses, proteins and even at such smaller sizes as of DNA can create a large arsenal of highly specific and ultra-sensitive biosensors and systems. From a long list of nano- scale solid- state biological sensors pursued in our lab, two important silicon based electrical frameworks will be discussed. These novel systems have been used to characterize DNA molecules. First, a method employing metal nano-electrodes with nanometer scale spacing will be presented. These nano-electrodes were used to measure the effects of the GC-content of the DNA on its DC conductivity. A dramatic decrease in conductance was seen on heating the DNA devices, analogous to an electrical fuse, attributable to complete or partial denaturing of the ds-DNA molecules that bridged the nanogaps. These findings have applications in non-optical detection of extremely low concentrations, biophysical studies of charge transport, and control of DNA-modified materials. Second, solid-state nanopores, progenitors of rapid and cheap next-generation DNA sequencing ³machines², selective to important DNA sequences will be described. To date, this work is the first evidence of engineering selectivity in solid-state nanopores. Distinctly different translocation signatures and event frequencies were discovered for important DNA targets. The selective solid-state nanopores realized in an array format can open avenues to novel devices for sequencing, detection of single nucleotide polymorphism, expression analysis, etc. as well as detection of specific proteins using specific ligand-receptor systems from very few copies of the analytes. Such selectivity can be electrically measured and can be used for direct label-free sequencing and detection of nucleic acids. These devices can potentially mimic the exquisite selectivity found in natural biological channels in cell or nuclear membranes, and help unravel the physics of selective and facilitated transport of bio-molecules in nanoscale channels. Dr. Samir Iqbal is working in the Laboratory of Integrated Bio-Nano Applications (LIBNA) in Birck Nanotechnology Center. He received his undergraduate degree in Electrical Engineering from NED University of Engineering and Technology, Karachi, Pakistan. He worked in various technical and management positions in academia, military, industry and nonprofits for five years before joining the School of Electrical and Computer Engineering at Purdue University in direct Ph.D. program. In graduate school, he received a number of awards and distinctions, most notably the Magoon Award for Excellence in Teaching from the College of Engineering and an NSF fellowship to attend summer school at Northwestern University, Illinois, USA. He received his doctoral degree under the supervision of Professor Rashid Bashir in February 2007.
