10:30 AM - QUANTUM ELECTRICAL METROLOGY DIVISION SEMINAR: What is the Charge Quantum That Moves in a SET pump (e or not e)?
Single-electron tunneling (SET) devices give us the amazing ability to move electrons around one-by-one in a solid-state device. A very natural question to ask is: Are the "electrons" in this solid-state device identical with free electrons in a vacuum? We have recently completed an analysis that compares the charge quantum in an SET device with the charge of a free electron. I will discuss our understanding of the theoretical question, present the experiment and the result, and discuss implications for supporting the future possible redefinition of the SI.

3:00 PM - POLYMERS DIVISION SEMINAR: Probing the structure of “Oriented” Nanoporous Membranes using Tomographic Small Angle Scattering
Nanoporous materials with defined pore structure and chemistry are critical to developing technologies in water purification and next-generation energy solutions. This ubiquitous class of materials utilizes structure and chemistry on the length scale of 1 to 100 nm to enhance chemical and physical selectivity. Producing nanopores with specific orientation while controlling size and surface chemistry is a significant challenge, especially over thicknesses of macroscopic dimensions found in most membrane applications. I will discuss efforts in the Polymers Division to develop techniques that probe the orientation and structure of “oriented” nanopores within membranes using both small angle X-ray scattering (SAXS) and small angle neutron scattering (SANS). Using data from recent experiments, small angle scattering is shown to provide significant detail on the distribution of orientation in unlabeled membranes while also providing information on pore shape and dimensions. These techniques are further extended to examine non-porous nanostructured materials such as block copolymer films. Finally, efforts to refine scattering models using 3-D TEM Tomography will be briefly discussed.

1/17 -- WEDNESDAY

10:30 AM - CNST SEMINAR SERIES: Mapping Uncompensated Spins in Exchange-biased Systems
Magnetic Force Microscopy is an ideal tool to image magnetic stray fields emanating from surfaces but also from hidden interfaces of magnetic or superconducting samples. A lateral resolution of 10nm is routinely obtained on flat samples. Tip calibration techniques were developed for a quantitative evaluation of the magnetic surface charge or surface dipole density from the measured MFM signal. The latter was performed to map the spatial density of pinned uncompensated spins (UCS) in exchange-biased ferromagnet/antiferromagnet multilayers. In order to further characterize these samples, different magnetization histories in magnetometry and magnetic force microscopy measurements were used advantageously to demonstrate the co-existence of pinned UCS that are parallel and antiparallel to the cooling field in metallic (IrMn) and oxidic (CoO) EB systems. We found that the exchange-bias-effect (EB-effect) is a result of pinned interfacial UCS, which are antiparallel to the spins of the ferromagnet. The often observed positive vertical shift of the magnetization loop after field cooling is due to pinned UCS that align parallel to the cooling field, but are of little importance for the EB-effect. Whereas magnetic force microscopy seems to reach its final state of development, considerable instrumental progress remains to be achieved in scanning force microscopy with true atomic resolution. A scanning force microscope optimized for surface science would allow the simultaneous measurement of vertical and lateral forces, energy loss and tunneling current. Our recent developments will be discussed.

10:30 AM - NIST COLLOQUIUM SERIES : Nuclear Power in Space
Space nuclear power and propulsion programs in the U.S. started in 1955 with the ROVER project and included ground testing of nuclear thermal rockets and the first ever deployment and in-space operation of the nuclear powered SNAP-10A in 1965. Key challenges for deploying this technology in space will be reviewed, including ultrahigh temperature nuclear fuels and materials, compact and lightweight reactors and shielding, space-suitable energy conversion systems, and launch and in-orbit safety of nuclear power systems. Some recent accomplishments will be described.

1/23/07 1:30 PM - ITL SEMINAR SERIES: Predicting Emergent Behavior in Systems
There has been a significant amount of research in adaptive systems in recent years using a variety of methods and approaches. Some exciting and suggestive results have been produced, but we still seem to be working around the edges of something fundamental about evolutionary systems, and particularly about emergence. Is there, or could there, even in theory, be an underlying mathematics of emergent properties yet to be discovered that would allow us to understand all manner of natural and synthetic systems? This talk will present some current projects at the University of Central Florida in human-agent systems and discuss underlying issues. Bio: Randall Shumaker is Director of the Institute for Simulation and Training (IST) in Orlando Florida, and Professor of Industrial Engineering and Electrical and Computer Engineering at the University of Central Florida. Previous assignments include Superintendent for Information Technology at the Naval Research Laboratory, Director of the Navy Center for Applied Research in Artificial Intelligence, and Manager for Aircraft Technology programs at the Naval Air Systems Command. His personal research interests include artificial intelligence, biomorphic computing methods, and advance techniques for software development. Dr. Shumaker is the author of more than fifty scientific publications and is a frequent speaker on a variety of technical topics. He has served as a reviewer for several professional publications and for federal agencies including DARPA, DDR&E, ONR, NASA, and ARL. He received a Ph.D. in Computer Science from the University of Pennsylvania, is a Professional Engineer, and a Commercial Pilot, SEL, MEL, IA.

2/9/07 1:00 PM - NIST COLLOQUIUM SERIES : The Quantum Optics Circus: Flying Photons, Acrobatic Atoms and Entangled Ensembles
NOTE: DIFFERENT TIME AND LOCATION (VTC from Boulder) Since its inception more than 40 years ago, Quantum Optics has made remarkable advances in the exploration of the quantum character of light, including the microscopic control of single atoms and photons. Indeed, laser operation has been pushed to the conceptual limit with the realization of a laser that operates with one acrobatic atom. Single, flying photons can now be generated deterministically at the push of a button. Ensembles of atoms can be projected into an entangled quantum state by the "click" of a photodetector. Beyond their fundamental significance, such advances are helping to lay the foundations for the new science of Quantum Information, including the realization of complex quantum networks.
