10:00 AM - CNST NANOFABRICATION RESEARCH GROUP SEMINAR: Optical Microcantilevers for Monitoring Bacterial Quorum Sensing
Pathogenic bacteria communicate with each other using signaling molecules. Their coordinated behavior, known as quorum sensing (QS), enables them to infect host organisms collectively and form drug-resistant biofilms. The interruption of bacterial signaling pathways can lead to new, more powerful antibiotics. Lab-on-a-chip technology has the potential to greatly accelerate the screening of candidate drugs for QS inhibition. In this work, we develop for the first time miniaturized sensors embedded in microfluidic channels to monitor the activity of an enzymatic pathway that produces bacterial signaling molecules. The sensors consist of gold-coated microcantilevers that deflect upon binding of the aminoacid homocysteine, a byproduct of the signaling pathway. The sensor response is measured by two newly developed optical methods that allow for conducting multiple experiments in parallel. The presented devices can be used as building blocks of future high-throughput systems for drug discovery.

10:45 AM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Room Temperature High Capacity Hydrogen Absorption in Nanoscale Transition Metal Based Organo Metallic Complexes
Using a highly sensitive pico-gravimeter they have discovered high capacity hydrogen absorption in a range of transition-metal(TM) based organometallic complexes prepared using physical vapor deposition techniques. Hydrogen absorption upto 14 wt% at room temperature has been measured in titanium ethylene complexes and confirmed by mass doubling when deuterium is employed instead of hydrogen. The speaker will present results of comprehensive measurements of hydrogen and deuterium in other TM-complexes of alkenes, alkanes and ring compounds. I will also discuss these measurements in the context of theoretical calculations based on first principles quantum mechanics that have appeared in the recent literature as well as in the context of previous experimental work in this area. Outstanding issues that remain going forward will be discussed.

11:00 AM - MSEL SUSTAINABILITY SEMINAR SERIES: EPA's Resource Conservation Challenge: Fostering Sustainable Materials Management
EPA's Resource Conservation Challenge (RCC) is a national effort to conserve resources and energy and reduce greenhouse gas emissions by managing materials more efficiently and effectively. The focus of the RCC is on four priority areas: (1) municipal solid waste reuse/recycling (2) electronics and green building, (3) industrial materials reuse and recycling and (4) priority chemicals reduction. Sustainable materials management is central to furthering the goals of the RCC. More specifically, these goals include: reducing waste generation by increasing reuse and recycling; reducing or eliminating toxic contaminants; and conserving resources and saving energy. Standards, specifications, and certifications continue to play an essential role in fostering sustainable materials management. EPA's Office of Resource Conservation and Recovery (ORCR) also is actively involved in reviewing products from external standard-setting organizations and certification programs (e.g. ASTM, ASHRAE, USGBC), helping to harmonize State pavement specifications on industrial materials recycling, tracking the development of green highway rating and certification systems, and examining ways to clarify green product standards. This presentation will include an overview of RCC program goals, priorities, and benefits; highlight EPA's work with standard-setting organizations to promote effective materials management (e.g., our Responsible Recycling Practices for electronics recyclers, and our green highways work); and engage the audience in a dialogue on how EPA's ORCR can continue to collaborate with NIST. About the Speaker: Dr. Peter Grevatt is the Director of the Resource Conservation and Sustainability Division within EPA's RCRA Office. Peter is responsible for providing national leadership on EPA's sustainable materials management programs, with a focus on energy savings, greenhouse gas reductions, toxic chemical reductions and resource conservation achievable through reuse and recycling of municipal and industrial waste materials. Positions Peter has held previously at EPA include Chief of the national water quality monitoring program, Senior Science Advisor for EPA's waste cleanup programs, and Senior Health Scientist in EPA's Region 2 office in New York. Peter earned his Ph.D. in environmental health from New York University Medical Center and his B.A. in Biology from Earlham College.

4/2 -- THURSDAY

10:30 AM - METALLURGY DIVISION SEMINAR: Recent Developments in the Nanowire Based Gas Sensorics
The two main factors, which define the performance of gas sensors, are their receptor and transduction functions. The first defines the interaction of the analyte molecules with the surface of the sensing element: its rate, selectivity and reversibility. The second is the mechanism of conversion of this interaction into the output signal. Metal oxide quasi 1D nanostructure chemi-resistors, diodes and chem-FETs represent the modern chemical sensing platform, which is among closest ones to the real world applications. These ultra-small sensing elements offer the realization of novel approaches in control over receptor/transduction principals via: a) field induced effects; b) photo-assisted chemical sensing; c) self-heating algorithms; d) metal-insulator phase transitions e) surface and bulk functionalization. The application of the aforementioned principles recently led to realization of inexpensive and yet excellently performing real world sensing devices and analytical systems (e-noses) which combine ultra-small size and power consumption with great sensitivity and selectivity.

4/6/09 11:00 AM - MATERIALS SCIENCE AND ENGINEERING LABORATORY OFFICE SEMINAR: "One Century's Magic, Another Century's Science": Thinking Inside the Modern Microanalytical Instrumentation Research Box
"One Century's Magic, Another Century's Science": Thinking Inside The Modern Microanalytical Instrumentation Research Box Radislav A. Potyrailo General Electric Global Research Center, Niskayuna, NY New requirements for analytical measurements in gas and liquid phases for biomedical, industrial, environmental, homeland protection, and other demanding applications push the limits of existing detection concepts and technologies to the point where we may reach their fundamental performance limits. Thus, without violating the laws of physics, chemistry, and electronics and without crossing the border into the 21st century science fiction, we need to develop new practical analytical concepts. This lecture will stimulate your analytical senses by posing several fundamental and practical questions and demonstrating on how modern industrial research addresses these questions in the developments of analytical instrumentation with previously unthinkable capabilities.

4/30/09 10:30 AM - CNST NANOFABRICATION RESEARCH GROUP SEMINAR: Materials Challenges in Nanostructured ZnO-Conjugated Polymer Photovoltaic Devices
It has been widely recognized that increasing the sources of clean energy is absolutely critical for maintaining living standards while halting environmental degradation. Solar energy holds a great promise as a clean energy source, but current technologies are too expensive for wide usage. In addition to traditional semiconductor solar cells, organic photovoltaics (OPVs) have been targeted for inexpensive, lightweight applications, such as consumer electronics and field deployable sensors. A subset of OPVs, called hybrid solar cells, uses a wide bandgap oxide semiconductor as the electron acceptor. They take advantage of the environmental stability and high electron mobilities of metal oxide semiconductors, while largely retaining the solution-based processing available to organic semiconductor devices. In addition, the use of ordered nanostructures increases the area of the heterojunction, resulting in increased dissociation of photogenerated excitons and collection of charges. We focus on nanostructured ZnO – polythiophene (P3HT) heterojuctions. The challenges are to form oxide nanostructures with spacings that match the exciton diffusion length in conjugated polymers (~ 10 nm), to infiltrate high-molecular weight polymer in the dense oxide matrix, and to achieve efficient charge transfer at the heterojunction interface. In this talk, I will discuss progress made on each of the challenges and discuss future directions.
