OPPORTUNITIES **************** 4.1: "UPDATE ON NSF STC COMPETITION" THIS MESSAGE IS BEING SENT ON BEHALF OF CHRISTINE KING: Dear Deans, Department Heads, and Discovery Park and OVPR Center Directors, Following up on the message below, this morning I spoke with Joan Frye at NSF, who will be the new program director for the STC competition. Dr. Frye stated that the new RFP for the STC will not be released in May, and that she's hoping for early June. Also, when I asked about the eligibility limitations, she suggested the possibility that the institutional limitation on preproposals may be fewer than the five allowed for the last competition. Also, FYI, I've attached Arden Bement's comments re: the STC in his February NSF FY2009 Budget Request to Congress.I hope this information helps a bit in your planning for this competition. Bement's budget comments on Feb. 4 re: STCs Interdisciplinary research is alive and well at NSF, not only in the nature of the grants we fund, but also in our organizational structures and cross-Foundation partnerships. The 2009 budget request gives particular emphasis to interdisciplinary programs, centers, and multi-investigator grants. In 2009, we plan to establish five to seven new Science and Technology Centers. The STCs tackle frontier problems of national and global importance by developing innovative partnerships among disciplines and with business and industry. They speed the transfer of concepts for new technologies to the private sector. And, critically, they integrate research with the education of those who will be tomorrow's teachers and leaders in discovery and innovation. At the beginning of my presentation, I emphasized the potential economic returns that can accrue from NSF investments. However, there are other, vitally important returns: namely, those that serve national and global needs in energy, health, security and environment, and those that increase human understanding and wonder about the universe in which we live, from the smallest to the largest scales.

SEMINARS ******************** 3.1: Wednesday, May 7, 2008, 9:30, Pfendler Hall Auditorium: "Self-Assembled Soft NanoMaterials from Sugar Surfactants," by Dr. George John. ABSTRACT: The self-assembly of low molecular weight building blocks into nanoscale molecular objects has recently attracted considerable interest in terms of the bottom-up fabrication of soft nanomaterials. The building blocks currently used in supramolecular chemistry are synthesized mainly from petroleum-based starting materials. However, biobased organic synthesis presents distinct advantages for the generation of new building blocks since they are obtainable from renewable resources. Our research efforts are deeply devoted towards developing building blocks from renewable resources to generate soft materials such as new surfactants, liquid crystals, lipid nanotubes and molecular gels. Present talk illustrates few successful examples of generating self-assembled soft materials from agri-sources, through simple organic transformations and by enzyme catalysis. To take these materials to the next level, we successfully showed the utility of these hydrogels as drug delivery vehicles. Enzyme catalysis was used as a tool to make and break the hydrogels, which apparently triggered controlled drug delivery. Intriguingly, by combining biocatalysis, with principles of green and supramolecular chemistry, we developed building blocks-to-assembled materials. Also address the advances that have led to the understanding of chiral behaviour and the subsequent ability to control the structure of glycolipid nanostructures-derived from renewable resources-and the resulting impact of this on future material applications. We foresee that these results will encourage interdisciplinary collaboration between scientists in the fields of organic synthesis, materials research, novel surfactants, green chemistry, drug discovery to design, and develop biobased functional materials from under-utilized plant/crop based feedstocks, as new forms of materials, and energy needs. BIO: George John was born (1962) in Kerala, the southwest costal state of India. After obtaining his Ph.D. (1993) in Chemistry from Kerala University, India under the mentorship of Dr. C.K.S Pillai, Regional Research Laboratory, Trivandrum, he held a postdoctoral position (1994) at the University of Twente, The Netherlands. Subsequently, he was a research scientist at the Agency for Advanced Industrial Science and Technology (AIST), Japan. In the fall of 2002 he joined the Rensselaer Nanotechnology Center as a research faculty and pursued his research interests in the area of soft materials. Currently, he is an Associate Professor of Chemistry, the City College of the City University of New York. His research interests are in the broad area of organic and macromolecular materials chemistry; specifically includes biobased organic synthesis, self-assembled soft nanomaterials for functional applications, green chemistry, understanding growth mechanisms of nanostructures and designing new structures and multifunctional nanocomposites. 3.2: Friday, May 9, 2008, 9:30-10:30, BRK 1001 Dr. Ali Shakouri Baskin School of Engineering Univ. of California Santa Cruz We review solid-state devices that allow direct conversion of heat into electricity. We describe fundamental and practical limits of conventional thermoelectric materials. Novel metal-semiconductor nanocomposites are developed where the heat and charge transport are modified at the atomic level. Potential to reach high power densities and high conversion efficiencies will be discussed. We also describe how similar principles can be used to reduce heating in optoelectronic devices and make micro refrigerators on a chip in order to remove hot spots in integrated circuits. Biography: Ali Shakouri is professor of electrical engineering at University of California Santa Cruz. He received his Ph.D. from California Institute of Technology in 1995. His current research is on nanoscale heat and current transport in semiconductor devices, submicron thermal imaging, micro refrigerators on a chip and novel optoelectronic integrated circuits. He is the director of the Thermionic Energy Conversion center, a multi university research initiative aiming to improve direct thermal to electric energy conversion technologies. He received the Packard Fellowship in Science and Engineering in 1999, the NSF CAREER award in 2000 and the UCSC School of Engineering FIRST Professor Award in 2004. 3.3: June 11 and 12, 2008: 2008 Advanced Materials Characterization Workshop organized by the Center of Microanalysis of Materials (CMM) at the Frederick Seitz Materials Research Laboratory (FS-MRL) on the University of Illinois Urbana-Champaign campus. The two-day event features lectures given by our FS-MRL scientists who are experts in the mainstream analytical techniques that are important for both academic and industrial research work. Please see more detailed information in the attachment. The workshop will be held in the room ESB190 on June 11 and 12, 2008, from 9 AM to 5:30 PM.

Recap of the BNC Research Review, April 14th, 2008, ON BEHALF OF TIM SANDS
by Deborah S. Starewich 22 Apr '08

22 Apr '08

Dear Birck Nanotechnology Center member: If you were not able to attend the BNC Annual Research Review on April 14th, the presentations were recorded and will appear on the nanoHUB. In the meantime, I invite you to peruse a written (html) version of a portion of the overview presentation at: http://www.purdue.edu/dp/Nanotechnology/nanoatpurdue.php This draft report entitled "The Impact of the Investment in Nano at Purdue University: Peer-reviewed Publications as a Metric" represents our attempt to quantify (albeit in one dimension) the impact of the investment in the people, the community and the facilities in nanoscience, nanoengineering and nanotechnology at Purdue. Let me also take this opportunity to recognize Yan Zhao, Waleska Perez-Segarra, and Qicun Shi and Alexander Wei as the first recipients of the Birck Nanotechnology Center Research Citation Award for their paper, "Dithiocarbamate Assembly on Gold," which appeared in the JOURNAL OF THE AMERICAN CHEMICAL SOCIETY 127 (2005): 7328-29. This citation award is presented to the authors of the journal publication with the most citations in the Web of Science database for the two full calendar years following the year of publication. Publications with the lead author indicating the Birck Nanotechnology Center as an affiliation are eligible. A plaque will be mounted in the BNC. Speaking of plaques, you will also see two new plaques on the wall in the atrium very soon, recognizing the founding co-directors, Dick Schwartz and Jim Cooper for ³Exceptional Guidance and Leadership in the Formation of the Birck Nanotechnology Center.² Lastly, the poster, "Rapid electrokinetic patterning of colloidal particles with optical landscapes," by Stuart Williams, Aloke Kumar, and Steve Wereley received the highest number of votes during the poster session and, thus, an award of $300 (plus a gross-up to cover taxes) will be split equally among the authors of this winning poster.

This, in essence, is the underlying challenge in many problems in modern information systems. Belief Propagation (BP) has enjoyed tremendous empirical success in broadly addressing this challenge, in a diverse array of applications: image processing, decoding of channel codes, machine learning, statistical physics etc. However, BP is a heuristic; the lack of precise guarantees on its performance stands in stark contrast to its empirical success. In this talk we expand the analytical understanding of BP, and widen its applicability, by investigating its performance in a new domain: networking. We first motivate how the fundamental structure of many networking problems makes BP a natural fit for these problems, by focusing on three specific applications: wireless scheduling, sensor network self-organization, and resource allocation. We highlight its algorithmic simplicity, and demonstrate its empirical performance. We then show that the setting of networking problems allows for a deeper insight into BP itself. At the core of our networking applications lie canonical combinatorial problems: weighted matching and independent set. Our analysis reveals that, for these problems, BP is precisely a fast distributed implementation of linear programming. This insight has the potential to foster even better algorithms for the large spectrum of applications that BP is already applied to. We also demonstrate the first use of BP as a proof technique, using our analysis to establish fundamental structural properties of random instances· of weighted independent set problems. In conclusion, we comment on the potential of BP as a generic framework for distributed algorithms, on adapting it for new applications, and on the need for a richer exchange of ideas between the fields of communications and statistical learning and inference.

Immanuel. ABSTRACT: Several particulate processes such as emulsion polymerization and granulation are characterized by a distributed population, the control of which constitutes a means of inferential control of product quality. For example, the control of particle size distribution of emulsion polymers constitutes an inferential means to control the rheology and optical properties of the polymers. The research challenges underlying distribution control are the multi-scale nature of the processes and limitations in both on-line measurements and manipulations. Optimal distribution control can be achieved through use of population balance models that account for the underlying particle rate processes including nucleation, growth, aggregation and breakage. It is seen in our studies that the multi-scale control problem is facilitated indeed through an explicit consideration of the hierarchical nature of the process mechanisms in the controller formulations. In this talk, issues and methodologies for model development, numerical solution and controller formulation will be discussed, with applications to polymerization and granulation processes. BIO: Dr. Immanuel is a lecturer in Chemical Engineering at Imperial College London.

Rhoads. ABSTRACT: Parametric excitations arise naturally in a variety of resonant micro/nanosystems. While these excitations can render a number of beneficial system characteristics, including nearly-ideal stopband rejection and a lowered dependence on damping, full utilization of their potential requires that the resonant devices be highly tunable, in both a linear and nonlinear manner. This presentation will consider the modeling, analysis, and experimental characterization of a representative nonlinear, parametrically-excited, electrostatically-actuated microresonator. Experimentally-verified tunings used to acquire desired nonlinear system behaviors will be described and micro/nanoscale applications with distinct promise, including frequency-selective switching and resonant mass sensing, will be outlined. Ongoing research related to micro- and nanomechanical parametric amplifiers operating in both linear and nonlinear frequency response regimes will also be briefly discussed. BIO: Jeffrey F.

Rao. ABSTRACT: 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 extend the state of the art in titanium micromachining and do so in a manner that is inherently scalable to low-cost/high-volume manufacturing. The focus of this talk will be to detail these processes, their capabilities, and their use in the fabrication of micromechanical devices for biomedical applications. BIO: Prof. Rao received his bachelors in Material 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.

ABSTRACT: The demand of flip chip technology in high density packaging for advanced electronic consumer products is growing rapidly. Due to the decrease in device size and increase in functionality, electromigration has now become the most serious reliability problem in flip chip solder joints, especially the Pb-free. It has several unique features that are very different from the electromigration in Al and Cu interconnects. Solder alloy has a very small critical product of electromigration, thus it can fail at 103 A/cm2. Owing to the line-to-bump geometry in flip chip, current crowding occurs at the contact between the line and the bump and the failure mode of electromigration is a pancake-type void formation at the cathode. Again due to current crowding, whiskers can be squeezed out at the anode. Joule heating due to Al or Cu interconnects can cause a very large temperature gradient in the solder joint, so thermomigration accompanies electromigration. In this talk, these reliability issues of flip chip solder joints will be presented. BIO: King-Ning Tu received his B. Sc. Degree in Mechanical Engineering from National Taiwan University in 1960, M.

Marinero ABSTRACT: Magnetic recording aims to achieve recording densities of 1012 bits/in2 in the foreseeable future. Critical dimensions of the magnetic domains and the sensors required to detect their flux at this density will be of the order of 15nm or less. These nanoscale dimensions present major materials and fabrication challenges to both the magnetic materials utilized for storing the bits, and to the sensor devices. This talk will review ongoing efforts to achieve highly uniform nanostructured magnetic recording materials comprising magnetic grains (islands) of ¾ 5 nm in diameter, segregated by a secondary non-magnetic phase. Mesoscopic sensors based on GMR and TMR based ferromagnetic materials are expected to be inadequate for sensing magnetic domains ¾ 15 nm on account of thermal instabilities (mag noise) and spin-torque effects. Therefore, magnetic sensor devices employing non-ferromagnetic materials are needed. Nanoscopic semiconductor quantum well heterostructures offer a potential solution and I will describe our ongoing research in this area. BIO: Ernesto Marinero received his BSc and PhD degrees in Physics from Heriot-Watt University, Edinburgh, United Kingdom.

So far, the most common detectors are based on elemental semiconductors, such as Si and Ge. However, they are by no means perfect in tackling some of the important problems facing the modern society. For example, thin films solar cells are not yet as economical as coal/gas fired power generators. For homeland security applications, high energy radiation detectors are too bulky and require cryogenic cooling. In this talk I shall describe a joint effort between theorists and experimentalists at Berkeley to look for new semiconductor detectors with better performance than existing detectors. On the experimental side, combinatorial techniques are utilized to allow for fast growth and characterization of a large library of new semiconductors synthesized by laser ablation. On the theory front, computational techniques are developed to allow for the prediction ofall the properties of semiconductors relevant to photon detection. By ³all², we mean electronic, optical, vibrational, transport, magnetic anddefect properties. While this ambitious project is still in progress, Ishall describe some new and interesting results we have found in the well-studied zincblende- and wurtzite-type semiconductors. We have obtained new insights into the effects of transition and rare-earth metal dopants, such as Cu and Gd, on the transport and magnetic properties of the host semiconductor. 3.6: Friday, April 18, 2008, 3:30PM, EE117: ³Multiphysics Modeling of Molecules and Materials,² by Hans Agren, Theoretical Chemistry, Royal Institute of Technology, Stockhololm Sweden ABSTRACT: With ³multiphysics modeling² we combine methods that have different physical content in order to obtain a more complete view of an applied problem. In materials science this can involve methods that bridge length and time scales; in length from atomistic to macroscopic levels through "electrons, atoms, grains and grids"; in time from femtosecond electron dynamics to slow processes perceived by humans. The combination can be obtained in terms of integrated algorithms or simply by piping datasets from one model to the other. Quantum mechanics is central in many such combinations as the microscopic light-matter interaction requires a quantum description. In the first part of my talk I will therefore describe some development in the quantum description of properties, in particular so-called response theory. Its implementation in the context of density functional theory, see e.g. [1], that is time-depdendent density functional theory (TDDFT), has been very successful in recent years in calculations of molecular properties also of quite large systems. Such applications cover a large wavelength region, from the X-ray region, over the optical and infrared regions and to the microwave and radiofrequency regions where electron and nuclear magnetic resonance experiments are carried out. In the final part of my talk I will bring up some contemporary research problems where the multiphysics concept has been applied, like; design of materials for optical control, where the combination of quantum mechanics (QM) and classical electrodynamics is applied [1]; the design of electro-optical switching materials through combination of QM and classical dynamics (QM and MD) [2]; studies of multiphoton induced light emission in quantum dots with QM coupled to statistical mechanics [3]; solvent effects on non-linear effects with polarizable continuum models [4], i.e. combining QM with dielectric theory.

ABSTRACT: Performance of optical delay lines and nonlinear devices based on slow wave propagation in photonic crystal waveguides in the presence of higher order dispersion is analyzed and compared with other slow light schemes, such as coupled resonators, media with electromagnetically-induced transparence, surface plasmons, and optical amplifiers. It is shown that higher order dispersion of gain and index severely limits the bit rate of the system. Novel methods for increasing the bit rate are proposed and analyzed. These methods range from mundane dispersion-compensation schemes to the most elaborate methods using adiabatic changes and various parametric processes. The conclusion is that the slow light is definitely anything but a ³silver bullet² for most purported applications, there still might be a practical niche for it. BIO: Jacob B.

Wednesday, April 9, 2008, 3:30, MRGN 121: "Nanobiotechnology: A Different Perspective," by Murali Sastry ABSTRACT: The study of the synthesis, exotic properties, assembly/packaging and potential commercial application of nanomaterials is an extremely important topic of research that is expected to have far-reaching global impact. The focus of my talk will be on an emerging branch of nanotechnology that derives its inspiration from biology. Recognizing that some of the most exquisite and highly functional nanomaterials are grown by biological systems (examples include silica by diatoms and magnetic nanoparticles by magnetotactic bacteria (1), many researchers have focused attention on understanding how inorganic materials are made by biological systems and attempting to replicate such processes in the lab. In my laboratory, we have investigated the use of plant organisms such as fungi in the synthesis of nanomaterials over a range of chemical compositions that include metals [2], metal sulfides (3) and oxides (4). An exciting development is the use of plant extracts in nanoparticle synthesis (5) wherein large concentrations of gold nanotriangles have been obtained that have potential application in cancer hyperthermia. Organisms such as fungi are not normally exposed to metal precursor stresses that they should be capable of a broad range of biochemical transformations to negate these stresses is useful in materials chemistry and throws up exciting possibilities. Recently, we have also shown that bacteria may be 'trained' to synthesize magnetite when challenged with suitable iron complexes under aerobic conditions (6). References: [1] Sarikaya, M. Proc. Natl.
