10:30 AM - PHYSICS LABORATORY SEMINAR: FTS Spectroscopy of Iodine Cells and Planets Around Nearby Stars
Most of the known extrasolar planets have been found with Iodine cell precision Doppler programs. These Iodine systems are currently used on telescopes at Keck, Lick (University of California), the AAT (Australia), VLT (Chile), Magellan (Chile), Subaru (Hawaii), HET (Texas), TNG (Italian National Telescope), and others. Achieving precise velocities with these systems requires calibrating the Iodine cells with an ultra high resolution FTS spectrometer, such as the NIST FTS. This talk will describe the computationally intensive data reduction, including recovery of the telescope+spectrometer point-spread-function.

10:30 AM - POLYMERS DIVISION SEMINAR: Crystallizable Block Copolymers: Directing Crystallization Via Polymer Architecture
Designing two or more self-organizing mechanisms into a single polymer chain--such as crystallization of one block and repulsion between unlike blocks--yields both morphological richness and kinetic complexity. In crystallizable block copolymers, the final structure and properties can be governed by nanophase separation in the melt, block crystallization, or a combination of the two dictated by the processing history. However, even when the block copolymer forms a homogeneous, low-viscosity melt, the block copolymer architecture can still exert substantial control over the nanoscale structure. For example, by attaching an amorphous block of predetermined length to the crystallizable chain, we can induce the crystallizable block to fold a precise number of times, thus precisely tuning the crystal thickness (and hence melting point) thermodynamically. We are currently investigating crystalline-amorphous block copolymers derived from ring-opening metathesis polymerization (ROMP), which permits the synthesis of a crystallizable block free from chain defects, and by a hybrid ROMP-anionic polymerization strategy. In such high-crystallinity materials, a tight coupling between microdomain and crystallite orientation is readily achieved, so that strong orientation of the crystal axes can be obtained by pre-aligning the microdomains. For example, we have prepared macroscopic specimens of polyethylene-containing block copolymers with a strong a-axial or b-axial texture, to complement the usual c-axial texture obtained by fiber spinning. In addition, we have synthesized triblock copolymers with crystalline endblocks, and pentablocks with crystalline and glassy outer blocks, in an approach to design solvent-resistant, easily processed thermoplastic elastomers. block copolymers derived from ring-opening metathesis polymerization (ROMP), which permits the synthesis of a crystallizable block free from chain defects, and by a hybrid ROMP-anionic polymerization strategy.

2:00 PM - CNST OUTREACH SERIES: MEL Introduction to NIST's Center for Nanoscale Science and Technology and the NanoFab
This meeting with the Manufacturing Engineering Laboratory is part of a series of presentations to introduce the staff to NIST's newest operating unit, the Center for Nanoscale Science and Technology (CNST). An overview of the CNST will be presented which will provide a brief description of CNST's structure, which consists of both a research program and the NanoFab, a shared-use nanofabrication and nanoscale measurement facility. A strong bias toward collaborative work being among CNST's prime attributes, the overview will describe how NIST staff can go about collaborating with scientists in the research program or make use of the NanoFab. The NanoFab, which provides economical access to a wide variety of advanced lithography and microscopy tools, will be described. Examples of recent nanofabrication projects will be used to illustrate our capabilities. Finally, the process for becoming a NanoFab user or having a nanostructure made or measured for you will be outlined. The laboratory by laboratory series of presentations has been designed to allow significant time to answer questions and tours will be arranged.

2:30 PM - POLYMERS DIVISION SEMINAR: A Model of Semiflexible Filaments and Hydrodynamic Behavior
Semiflexible networks demonstrate rheological properties markedly different from flexible polymers. Dynamic simulation of the semiflexible networks would help us understand the rheological anomalies and unite their behavior under a single theory. However, the string-of-beads idealization used to model semiflexible filaments makes it computationally expensive to model even a single filament. Moreover, hydrodynamic interaction, which affects the bending fluctuations of a filament, is commonly modeled using first-order superposition of Stokesian solvent flows. The first-order superposition neglects the hydrodynamic influence of stationary filaments. We proposed a new string-of-rods idealization of semiflexible filaments. In this idealization we solve for the Euler bending mechanics between continuously curved rods instead of beads. This not only reduces the number of equations to be solved, but is also physically more accurate. We model hydrodynamic interaction by a new implicit version of the first-order Stokesian superposition. A one-step implicit solution is equivalent to infinite orders of Stokes superposition, and we show that it captures the hydrodynamic confinement of a semiflexible filament between two stationary filaments. To summarize, our proposed model of semiflexible filament avoids the common physical approximations used to capture semiflexible behavior, but is also computationally cheap, making the extension to network studies relatively easy. In this talk I will give an overview of the ideas used in our filament model, and also focus on how hydrodynamic interaction affects the Brownian fluctuations of even a dilute semiflexible filament.

7/21 -- TUESDAY

10:45 AM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Phase Behavior in Asymmetrical Ternary Blends of Polyolefins
Ternary polymer blends of the A/B/A-C type comprise two immiscible homopolymers, A and B, along with a diblock surfactant, A-C. The interspecies interactions, as characterized by the Flory-Huggins-parameter, are tuned to enable access to thermodynamic microphases such as lamellae and microemulsions. Asymmetry is introduced as a disparity in the chain lengths of the A and B homopolymers, enabling independent control over the volume fraction of a species and its entanglement with the surfactant. The resulting phase behavior is discussed in terms of the diblock phase diagram, wet and dry brush regimes, and within the context of the random phase approximation.

11:00 AM - STATISTICAL ENGINEERING DIVISION SEMINAR: Neutron Transmission Tomography of a Fuel Cell
In a proton exchange membrane fuel cell, water is formed as a by-product of the reaction between hydrogen and oxygen. Since water has a high neutron scattering cross section, neutron imaging is an ideal method for measuring water in a fuel cell. Earlier, we proposed a method to reconstruct a two-dimensional nonnegative residual attenuation image from joint analysis of the wet and dry state projection data with a penalized Poisson likelihood method with a Huber penalty function. Here, we reconstruct experimental data collected at the NIST Neutron Imaging Facility. The regularization parameters in the Huber penalty function dramatically affect the smoothness of the reconstruction. We select these parameters by a statistical learning method called cross-validation. We also characterize the spatial correlation structure of observed projection data. This talk is based on joint work with D.F. Vecchia, D.S. Hussey and D. L. Jacobson.

3:30 PM - SURF SUMMER SEMINAR SERIES: Statistics -- A Contact Sport
The subject of "statistics" more often than not stirs memories of boring lectures, irrelevant textbooks, and impossible homeworks -- just ask any student of nursing or anthropology (who, in most schools, must take at least one statistics course), about their encounters with statistics... The funny thing about statistics is that it has made (and undergone) its most consequential advances in the hands of geneticists, chemists, geophysicists, and agronomists. Then there is the probability part, which we all are familiar with because we know about odds in gambling, and chances of rain. Statistics courses usually dedicate a good deal of attention to probability. But do we ever get to figure out what relation there may be between familiarity with games of chance and the evaluation of risks in real life (of an earthquake or a hurricane, or of an accident at a nuclear power plant)? This talk tells several statistical tales that attempt to suggest that there is a lot more to statistics than has met the eye of many the suffering nurse or pained anthropologist; that probability is the language of statistics; that statistics is the art of dealing with vagueness and with interpersonal difference in decision situations; and that statistics is best practiced, and then makes a difference, when it involves collaborations between professional statisticians and scientists (geneticists, chemists, geophysicists, argonomists, etc.), jointly to advance knowledge -- that is, when it is "played" as a "contact sport."

10:30 AM - CHEMICAL SCIENCE AND TECHNOLOGY LABORATORY OFFICE SEMINAR: NCI Imaging Research Networks: Opportunity for NIST participation
This presentation will address the development and implementation of two networks that will address the development of imaging research and related standards at a national and international level. These research networks address research performed on both current commercial imaging platforms and the next generation of multi modality and molecular imaging platforms. The imaging platforms include external tomography and localized catheter based systems using MEMS technology, with molecular resolution in the micron range. The clinical validation of these platforms including pathology correlation poses significant metrology problems that are of great interest to NIST. The networks' goals include an open science approach to validate these imaging methods and to encourage the development and implementation of imaging standards, consistent with the goals of the NIST biomarker workshop held in Sept 2006. These networks are governed by a steering committee and an external advisory committee, with a provision of representation from other agencies of the federal government such as NIST and FDA. In addition the networks will include the creation of research cores, and the creation of public web accessible databases, to help drive the development of imaging standards. The goal of this presentation is to review the networks' scientific scope and to seek the interest of key scientists at the different laboratories at NIST that may wish to participate on one or more of the research network oversight committees and/or research cores.

10:30 AM - POLYMERS DIVISION SEMINAR: Ionic Conductivity and Molecular Mobility of 'Single Ion' Polymer Electrolytes
Polymer electrolytes play a critical role in energy storage and conversion devices such as batteries and fuel cells, enabling ion transport between the active components of the device. Despite the great practical importance of these materials, and after several decades of research, many aspects of ion transport through polymeric membranes are incompletely understood. This presentation will provide an overview of our recent work on cation transport in PEO-based 'single ion' polymer conductors. [e.g. 1-3] The materials studied here have low conductivity for most practical applications (less than 10??5 S/cm at room temperature). However, they are excellent model systems in that they are single-phase materials, amorphous at room temperature, exhibit little ion clustering of the type typically observed in ionomers, and the conduction measured is due exclusively to the motion of cations [in contrast to polymer + salt mixtures]. One series of copolymers studied consists of PEO segments (of molecular weight 600) separated by Li-neutralized sulfonated isophthalate or neutral isophthalate groups. The total ion concentration is controlled by systematically varying the fraction of ionic isophthalate groups from 2.5% to 100%, corresponding to a ratio of ether oxygens to Li+ ions of 520:1 to 13:1 (EO:Li). Broadband dielectric (impedance) spectroscopy is the principle tool used to explore polymer dynamics and ion transport in our studies. Four dielectric relaxations were observed for these materials. The segmental ?? process slows down with increasing ion content above a critical concentration, showing decreasing fragility with increasing ion concentration. Two slower processes are present: an "ion mode", assigned to rotation of separated ion pairs, and a weak low frequency process. In addition, analysis of the static dielectric constant suggests that a significant fractions of ions form separated ion pairs. An increase in molar conductivity is observed for higher ion content. Using a physical model of electrode polarization, dc conductivity was decomposed into the contributions of 'free' ion concentration and ion mobility. The overall features of the ion concentration and mobility parallel those that have been observed for other single ion conducting and polymer-salt polymer electrolytes. This can be summarized as follows: Due to the low dielectric constant but strong Li-complexing ability of PEO, many ions are present as separated ion pairs. These thermally dissociate and release unpaired cations that rapidly form Li+SO3 ??Li+ triple ions. In addition, we propose a hopping mechanism for conductivity involving those transient triple ions, which rationalizes the observed increase in ion mobility with increasing ion content.

11:00 AM - MSEL SUSTAINABILITY SEMINAR SERIES: Water Science Technologies for Sustainable Water Supply and Purification
The problems facing the world with water are exponentially growing, and are impacting energy, the environment, agriculture, and the health of people throughout the world. New technologies holds promise to clean impaired waters of contaminants, to disinfect water from a host of pathogens, reuse waters, and desalinate seawater and most importantly inland saline aquifers that underlie most of the United States and world. Current purification techniques rely mainly on homogeneous chemistries and phase change, but heterogeneous purification techniques, such as reverse osmosis, have been gaining in use. Numerous heterogeneous technologies are being developed that can fundamentally change how water is purified. Nanotechnologies, such as incorporation of nanoparticles and nanostructures within membrane systems, are being developed to greatly increase the performance of membrane separation processes, decrease fouling of membranes and to increase flux in order to increase water supplies through reuse and desalination. Micro-nanofluidic constructs are being employed to selectively add and subtract attomolar concentrations of species to separate, manipulate, and analyze minute amounts of specified molecular compounds, such as toxins and proteins, from natural water. Catalysts are being developed to mineralize potent carcinogens and toxic compounds in water, as well as to disinfect pathogens by photooxidation while decreasing the use of potent chemical oxidants, which themselves can create toxic disinfection byproducts. New point-of-use, -source, and -discharge technologies are being developed that permit robust, distributed, non-centralized systems that can be applied throughout the world. An emerging trend is to convert biomass in wastewaters to high-quality energy, either directly to electricity (such as with microbial fuel cells) or to methane. The waste biomass sources include human sanitary and animal wastes to plant and farm crop residuals. While the problems are great, so too are the opportunities with new technologies and water businesses that can increase economic output and U.S. competitiveness. About the speaker: Mark A.

7/28/09 10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: Precision X-Ray Spectroscopy of Highly-Charged Ions From Low-Energy Ion Sources
Spectroscopy of highly-charged ions has been used for 3 decades to test QED in strong electromagnetic fields. It also has applications to plasma physics. Experiments evolved in two parallel lines: - beam-foil spectroscopy, with large Doppler shift and broadening-dominated uncertainties (~25 ppm at best) to storage ring experiments for very heavy elements with better control of the Doppler effect (using laboratory frame X-ray standards) - spectroscopy based on highly charged ion sources using X-ray reference lines (typically from X-ray tubes) to absolute energy measurements in Heidelberg (using an EBIT) and Paris (using an Electron-Cyclotron Resonance Ion Source) In this talk I will describes recent advances in absolute highly-charged ions X-ray transitions energy measurements, show preliminary results and describe difficulties to be overcome to get X-ray measurements of transitions like the 1s2s 3S1- 1s2 1S0 relativistic M1 transition in heliumlike Ar or the 1s 2s 2p 2PJ-1s2 2s 2S1/2 transition in lithiumlike Ar using a double-flat crystal spectrometer.

7/30/09 10:30 AM - CNST ENERGY RESEARCH GROUP SEMINAR: 1/f Noise Characterization of n- and p-type Polycrystalline Silicon Thin Film Transistors
Polycrystalline silicon has drawn attention from researchers due to its higher mobilities compared to amorphous silicon (a-Si), which is currently used in the majority of thin film transistor (TFT) sensor arrays. Higher mobilities of poly-Si TFTs allow faster switching and higher transistor drive capabilities compared with a-Si TFTs, enabling build of more complex sensor arrays with smaller pixel sizes while maintaining sufficient gain. A limiting factor in the performance of TFT sensor arrays is the high level of 1/f noise from individual transistors incorporated in each pixel. This talk will discuss the low frequency noise behavior of poly-Si TFTs. Several factors contribute to the noise characteristics of these devices, including carrier number, trap density, and strong coulomb interactions. The data is compared to existing models that provide a theoretical framework for these observations.

7/30/09 11:00 AM - STATISTICAL ENGINEERING DIVISION SEMINAR: Spreadsheets and Good Statistics: A Tale of Love and Hatred
When statistical rigor and common practice meet, paradigms clash. Statistical computing, the use of spreadsheets, and in particular the use of Microsoft Office Excel, frequently arouse disagreement for the sake of correctness on the one side and ease of use on the other. On the one hand, spreadsheets can be credited with giving the masses the ability to store, analyze, visualize, and even model data. I believe that a very large majority of all statistical work carried out in the world, and in particular in industry, is done exclusively using spreadsheets, most of it in Excel. The reason for this popularity is that they provide intuitive, flexible, and comprehensive ways for arranging data, looking at them, performing calculations, building interfaces for day-to-day use, and even for distributing applications within a company or organization. On the other hand, it is well-known that many spreadsheets and in particular Excel have numerical flaws which render them unacceptable to statisticians concerned with numerical correctness and statistical rigor. Moreover, the way spreadsheets are constructed and used leads towards data analytic 'video gaming' and does not provide a foundation for reproducible research. This talk is about reconciling the world of good statistics with the use of spreadsheets. It starts with a reminder of what any practicing statistician should know about the spreadsheet paradigm (automatic recalculation, tabulation of expressions, cross tabulation, optimization, and integrated interface design). It then continues by describing a way of extending the ability of Excel to carry out 'good' statistical computations by adding a bridge to the R language. Statisticians need not hate spreadsheets as long as they know how to use what's good and how to avoid what's bad. I argue that statisticians should even learn to love spreadsheets for their unique potential for giving statistical power to the people.
