1:30 PM - OPTICAL TECHNOLOGY DIVISION SEMINAR: The Situation of UV and fluorescent Optical Radiation Standards in Japan and Development of Standard Devices at Hamamatsu Photonics
The applications of ultraviolet radiation from vacuum UV to air UV in the industries are expanding in Japan both qualitatively and quantitatively. The cleaning utilizing UV radiation in semiconductor industry, surface modification, photocatalysts in building and automobile industries, LED illumination, ultraviolet light curing, fluorescence in in-vitro clinical testing are prominent among those applications. The standardization is becoming more and more important to achieve accuracy and ensure safety in controlling the reaction process, operation process, and clinical testing. The high level of accuracy in quantifying the light sources used in those processes and clinical testing instruments is highly demanded. Hamamatsu Photonics has long been involved in the business related to standardization, and has recently developed the devices as below: 1) Power meters to monitor the vacuum ultraviolet light source used for cleaning and surface modification in semiconductor manufacturing process. 2) Power meters to monitor ultraviolet light sources for sterilization of various materials. 3) Power meters for ultraviolet LEDs. 4) Standard light sources for standardization of fluorescence and chemiluminescence for clinical testing instruments. We would like to discuss the details, background, and applications for those devices in this opportunity. Your comments over our presentation will be highly appreciated. Also, it will be our pleasure to discuss with the NIST people on how we can fulfill the needs in the USA.

10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: Single Photon Technology, Metrology, and perhaps a bit of Ontology
Single-photon detectors and sources are key to increasing the utility of applications ranging from remote sensing and medical imaging to quantum information. We present a summary of our efforts to develop enhanced single-photon detectors, sources, and processors. These include better detectors that allow improved counting rates, lower background rates, and photon number resolution. In the area of sources we are developing single-photon sources that are more efficient, have higher production rates, have lower background rates, and are better able to produce entanglement, which is key to quantum information applications. As for processors, we are working on a quantum memory for entanglement storage. In addition to the device development efforts, we are working to improve the metrology of these devices and to disseminate that improved accuracy to the single-photon community. Finally we are using the results of all of these efforts to test questions of fundamental physics and even one of the oldest and most fundamental questions of all- What is the nature of Reality?

10:45 AM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Towards Colder Neutrons: Developing the Next Generation of Neutron Sources
The production of long wavelength neutrons is typically accomplished by thermalizing neutrons in a cold medium such as methane or hydrogen. However, accurate calculation of thermalized neutron spectra is complicated by a lack of validated data on the neutron transport properties of standard materials at cryogenic temperatures. The speaker will discuss his experiences at the Indiana University Low Energy Neutron Source in calculating and validating neutron transport calculations for the production of cold (~1 meV) neutrons and propose an extension of the source to the production of ultra-cold (~100 neV) neutrons. Finally, the impact of improved transport models in the case of cryogenic polyethylene as a model for future improvements will be reviewed.

1:00 PM - NANOFABRICATION RESEARCH GROUP SEMINAR: Synthesis and Applications of Uniform Two-dimensional Nanoparticles Arrays
Two dimensional nanomaterial arrays are important platform for many applications. Despite many efforts, organizing nanomaterials into desired structures is a grand challenge in nanoscience and technology. In this presentation, a polymer template approach for synthesizing uniform metal nanoparticle arrays with controlled particle size and interparticle spacing will be demonstrated. These metal particle arrays are ideal model catalysts for fuel cell research and are used to reveal the catalyst structure-activity relationship. O2 reduction as well as CO oxidation will be used as examples to illustrate the applications of the metal nanoparticle arrays in electrocatalysis. In addition to catalysis, these metal nanoparticle arrays can be used as the seed to form other organized nanomaterials. Results from the seed-mediated growth and electrochemical deposition will be discussed to demonstrate the applications of the metal nanoparticle arrays in material synthesis. Some measurement challenges in these applications will also be discussed.

10:30 AM - POLYMERS DIVISION SEMINAR: Polymers Division Seminar: Scanning Fiber Endoscopy -­ Overview and Future Directions
Conventional flexible endoscopes rely on one sensor element for each display pixel, so that size limitations of the endoscope also limit spatial resolution of images acquired. A completely new type of endoscope has been designed and fabricated at the University of Washington, Human Photonics Laboratory that circumvents these constraints. In this new design, a single optical fiber is used to project a single spot of RGB laser light onto the tissue, and is scanned across the tissue with a micro-optical scanner and lens assembly that is 1 only mm in diameter. The backscattered RGB light from the tissue is collected by a ring of optical fibers at the distal tip of the endoscope, which surrounds the central micro-optical scanner, making the current endoscope 1.2 mm in outer diameter. This approach is used to create 500-line color images at 30 Hz with fields of view of 100 degrees. Very soft and supple shafts are achievable with this approach, allowing in vivo imaging of a pig bile duct and unsedated imaging of the human esophagus. This forward-looking presentation will address the unique design features of the endoscope, and how they can be exploited to allow a variety of signal excitation and detection modes and photodynamic therapy with only minimal modification of the endoscope probe's distal tip.

10:30 AM - CNST ELECTRON PHYSICS GROUP SEMINAR: Nonlocal and local magnetization dynamics excited by a rf magnetic field in magnetic multilayers
A microwave study in spintronic devices has been actively pursued in the past several years due to its fertile physics and potential applications. A passive use of microwave can be very helpful to understand the spin dynamics in spintronic devices. On the other hand, an active use of microwave yields a great potential for interesting applications which gives new functionalities into spintronic devices. For instance, a spin wave excitation by a rf field can be used to reduce the switching field of a ferromagnet, which could be potential applications in an advanced recording media. More interestingly, a precessing magnetization driven by a rf field can inject spin currents into a neighboring layer, i.e. nonlocal magnetization dynamics (or spin pumping effect) which is one of the candidates for generating a pure spin current. In the talk, I will present my work on a microwave study in magnetic multilayers and magnetic tunnel junctions and show the experimental results of the local and non-local magnetization dynamics excited by a large rf magnetic field.

10:30 AM - OPTICAL TECHNOLOGY DIVISION SEMINAR SERIES: State-of-the-art detector standards and spectral responsivity scales
Along with stable monochromatic sources, high-performance transfer-standard and working-standard detectors/radiometers play a critical role in the realization and maintenance of spectral responsivity scales. These devices are needed to transfer the reference scale from the cryogenic radiometer to different NIST calibration facilities and field applications. These detector standards also enable irradiance and radiance responsivity calibrations. They often dominate the uncertainties of the realized and derived scales. For these purposes, we have developed state-of-the art radiometers, photometers, colorimeters, and pyrometers in the wavelength range from 200 nm to 24 ?m. These devices utilize different types of detectors and are optimized for long-term stability, large dynamic signal-range, temperature stability, spatial uniformity, high sensitivity, and linear operation. Using these NIST-developed new detector/radiometer standards, realizations of two SI base units, the candela and kelvin, are being improved, and a low-uncertainty reference spectral irradiance responsivity scale (for SIRCUS) is being established. Low noise-equivalent-power and low-uncertainty IR radiometer standards are being developed to extend the spectral responsivity scale to 24 ?m. Fundamental developments and scale transfers to NIST facilities will be described. Also, the applications of the detector/radiometer standards and reference scales in various military and international projects will be discussed.

1:30 PM - BIOPHYSICS SEMINAR: Terahertz Imaging and Spectroscopy based on HEB Heterodyne Detection
Imaging and spectroscopy at terahertz frequencies have great potential for healthcare, plasma diagnostics, and homeland security applications. Terahertz frequencies correspond to energy level transitions of important molecules in biology and astrophysics. Terahertz radiation (T-rays) can penetrate clothing and, to some extent, can also penetrate biological materials, and because of their shorter wavelengths they offer higher spatial resolution than microwaves or millimeter waves. We are developing hot electron bolometer (HEB) mixer receivers for heterodyne detection at terahertz frequencies. HEB detectors provide unprecedented sensitivity and spectral resolution at terahertz frequencies. We describe the development of a two-pixel focal plane array (FPA) based on HEB technology. Furthermore, we have demonstrated a fully automated, two-dimensional scanning, passive, imaging system based on our HEB technology operating at 0.85 THz. Our high spectral resolution terahertz imager has a noise equivalent temperature difference (NE?T) value of better than 0.4 K and a spatial resolution of a few millimeters. HEB technology is becoming the basis for advanced terahertz imaging and spectroscopic technologies for the study of biological and chemical agents over the entire terahertz spectrum.

4/29/08 10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: High Temperature Single-Electron Transistor Fabricated by a Nanodamacene Process
Since the late 80's, Coulomb blockade (CB) devices have been pursued, among other reasons, for highly integrated logic devices. Many processes have since been proposed, but most do not operate above cryogenic temperatures. This limitation is due to the fact that the charging energy of the island (Ec) must be larger than kt, for good device performance. Recently, we have reported a nanodamascene process showing CB up to 130°C [1]. This process enables one to build metallic nano-wires interspersed with low-capacitance tunnel junctions, which not only allow high temperature operation, but also increase the voltage gain (Gv) of the CB transistors. This is very important, since the Gv 1 criterion is a necessary condition for CB transistors to be combined in circuits, and is rarely met in the literature. [1] C. Dubuc, J. Beauvais, D.

5/1/08 10:30 AM - CNST NANOTECHNOLOGY SEMINAR SERIES: The bright future of nanophotonics: recent advances and challenges
Nanophotonics in which light is manipulated at subwavelength scales is emerging as one the most exciting and potentially useful areas of physical optics. I will highlight recent research in my group aimed at a new class of light-sources in which the near field and the far-field properties are fundamentally altered by means of plasmonic nanostructures and metamaterials monolithically integrated on the laser facets. As a platform to demonstrate these new beam shaping concepts, such as reduction of beam divergence, nanospot light concentration, super-focusing and polarization control, we have used mid-infrared and near-IR lasers but these techniques are broadly applicable to all solid-state lasers. I will also discuss a novel technique called nanoskiving that combines photolithography, thin-film metal deposition, and thin-film sectioning, and demonstrate its capabilities in the realization of metallic nanowires with engineered plasmon resonances and frequency selective surfaces.

5/1/08 10:30 AM - OFFICE OF TECHNOLOGY PARTNERSHIPS TECHNOLOGY TRANSFER SEMINAR SERIES: Scientists as Inventors: Engineers by Necessity
Throughout history, many scientists have emerged as some of the most creative engineers the world has ever seen by crafting solutions to technical problems that were barriers to their research. Sometimes by accident, sometimes reluctantly, often born of frustration, and always out of necessity, research scientists have frequently "engineered" their way around practical problems in observation and measurement that threatened to bring their research to a grinding halt. The results of their problem-solving were often embodied in innovative technology that later had profound impacts on society. Who can tell? Your invention might be among these. Acclaimed author, scholar and authority in engineering design and failure, Professor Henry Petroski uses his knowledge of innovation, invention, "The Evolution of Useful Things," and historic perspective to create for us some unique insights into the nature of invention. Professor Petroski received his bachelor's degree from Manhattan College in 1963 and his Ph.D. from the University of Illinois at Urbana-Champaign in 1968. He is a professional engineer registered in Texas, and a chartered engineer registered in Ireland. He has authored fourteen books and hundreds of newspaper, magazine, and technical journal articles. Professor Petroski has been a faculty member of the Duke University Pratt School of Engineering since 1980. Among his many honors are Member, National Academy of Engineering; Fellow, American Society of Civil Engineers; and Fellow, American Society of Mechanical Engineers.

5/16/08 1:30 PM - CENTER FOR NANOSCALE SCIENCE AND TECHNOLOGY SEMINAR: Spin Wave Beams, Precessing Vortices, and Localized Standing Waves in Single Layer Nanocontacts
The recently discovered spin transfer effect enables the application of localized torques in magnetic thin film nanostructures. In the point contact geometry, this effect can result in large amplitude spin wave generation. The well studied Slonczewski model of spin torque in trilayer nanostructures is the Landau-Lifshitz equation modified with a local spin torque term. In this talk, a non-local model of point contacts in single layer thin magnetic films is presented and studied numerically in two spatial dimensions. Here, the spin torque term in the Landau-Lifshitz equation is non-local and is due to spin diffusion effects. A variety of quasi-periodic mode solutions to this equation are found including localized standing waves, vortex spiral waves, and a weakly diffracting collimated beam of spin waves, the direction of which can be steered by changing the direction of an applied magnetic field. The spin wave beam appears to be the nonlinear hybridization of the vortex spiral waves and the localized standing wave. Mode selection is explained using linear spin wave theory.
