10:30 AM - OPTICAL TECHNOLOGY DIVISION SEMINAR: Advances in fluorescence lifetime imaging microscopy (FLIM) for monitoring dynamic processes in biological specimens
Biophysics Group Seminar: (Abstract of the seminar) Our laboratory has pioneered frequency-domain, video-rate FLIM and rapid analysis techniques for convenient, model-free visualization of lifetime components for every pixel within an image. I will describe the basis of the technique and recent work by our laboratory to develop image analysis routines to denoise the lifetime data and to separate lifetime components within the images based on spatial morphology. The following examples will be discussed: (1) FLIM experiments for measuring Förster Resonance Energy Transfer (FRET) in live cells expressing genetically encoded FRET-based redox sensors; (2) video-rate FLIM imaging for distinguishing protoporphyrin IX (a photo-activated therapeutic agent for cancer treatment) monomers and aggregates, as well as their dynamics during light irradiation; and, (3) preliminary findings that suggest FLIM can be used to help diagnose prostate cancer by imaging autofluorescence from tissue microarrays. For the Redox Biosensor, see a recent news release posted online. (VL Kolossov & BQ Spring. Engineering Chimeric Polypeptides to Illuminate Cellular Redox States. Press release.

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.

5/21/08 10:30 AM - STATISTICAL ENGINEERING DIVISION SEMINAR: Using Sequential Importance Sampling to Speed up MCMC
The Monte Carlo Markov Chain Method (MCMC) has been written about extensively and there is an extensive theory developed. But getting answers to problems is still difficult because MCMC can be slow. We present two methods for speeding up MCMC for the monomer-dimer problem based on the method of sequential importance sampling (SIS). Our method computes optimal fugacities. The other computes the mixing rate efficiently.

5/21/08 11:00 AM - MATERIALS SCIENCE AND ENGINEERING LABORATORY LECTURE SERIES: Hyperthermia Induction Modeling for Optically-Active Nanoparticles
Optical activation of gold-nanoshell particles with laser radiation in the near-infrared spectrum provides a means to induce hyperthermia in a tumor while leaving the surrounding healthy tissue intact. The procedure entails two processes: (i) heating of the nanoshells via a plasmon resonance phenomenon and (ii) diffusion of the heat from the particles into the surrounding tissue. Both processes are influenced by the density and distribution of particles within the tumor. Additionally, tumor-scale modeling of thermal ablation efficacy requires effective properties of tissue containing particles. Little is known about these effective properties. Moreover, while the dependence of plasmon resonance absorption on shell size and thickness is well documented, the dependence of plasmon resonance heating on nanoshell density and shell defects is not as clear. Mesoscale computer simulations are used to elucidate these two processes and to determine effective system properties and responses of nanoshell particle ensembles.

6/5/08 10:30 AM - CNST NANOFABRICATION RESEARCH GROUP SEMINAR: The Physics of Surface Waves at the Metal-Dielectric Interface Interacting with Structures of Subwavelength Scale
The localization, enhanced transport, and transmission of light along and through subwavelength structures holds promise for chip-scale photonic circuit integration, biological sensors, and dense optical storage media. The basic physics of this transport and transmission has been, however, imperfectly understood and attempts to rationalize early experimental results from the perspectives of crystal periodicity, classical physical optics, diffraction, and classical electrodynamics have led to diverse and often conflicting interpretations and predictions. We present here a series of studies seeking to explain the fundamental physics of a single propagating mode interacting with a single subwavelength structure and how this physics relates to transport and transmission through periodic arrays of such structures.

CROSS INDUSTRY ISSUES IN NANOMANUFACTURING
The National Institute of Standards and Technology is hosting a "Cross Industry Issues in Nanomanufacturing" Workshop, May 20 - 22, 2008 at NIST in Gaithersburg. The objective of the workshop is to identify common problems and common solutions specific to nanotechnology, manufacturing processes, and performance of nanomaterials in commercial products within widely different industries, including aerospace, automotive, chemical, food, forest products, medical technology, pharmaceutical, and semiconductor. The technical focus will be on the three highest cross-industry priorities identified in previous workshops and meetings as they apply to the design, synthesis, and production of nanotechnology-enabled products: -Characterizing nanomaterials and enhancing their separation and fractionation to address challenges in commercial production of uniform, high quality, stable, and consistent (reproducible) nanomaterials in high volume; -Understanding and controlling the surface-dependent properties of nanomaterials such as dispersion, aggregation, and adhesion at their interface with a matrix, with an emphasis on non-covalent bonding interactions; and -Understanding and controlling multiple properties of nanocomposites. Within each of these topics, common issues include, although are not limited to, measurement, characterization, modeling, performance properties, and environment health and safety concerns. Resource speakers will present needs as viewed by industry, with participation by all who attend. The workshop is sponsored by NIST, the American Forest and Paper Association, the University of Maryland Department of Materials Science and Engineering, Imerys, US Forest Service, and endorsed by the Nanoscale Science, Engineering, and Technology Subcommittee of the National Nanotechnology Initiative in collaboration with the Nanomanufacturing Industry Liason and Innovation Working Group.
