10:30 AM - FIRE RESEARCH DIVISION SEMINAR: Consumer Product Safety Commission's Annual Fire Loss Estimates
The Consumer Product Safety Commission (CPSC) uses various data sources to produce fire and fire loss estimates associated with specific consumer products. Different sets of estimates tell different aspects of the fire story. A basic question like how many fires and fire deaths and injuries related to candles, for example, occur in a given year does not have a simple answer. CPSC combines data from the National Fire Incident Reporting System (NFIRS) and the National Fire Protection Association's (NFPA) Survey of Fire Departments to produce annual estimates of fire department attended fires, deaths, injuries, and property loss from home fires. These NFIRS/NFPA estimates are the primary annual fire and fire loss estimates used by CPSC. But the NFIRS/NFPA candle fire estimate is limited to fires where the fire department attended. The National Electronic Injury Surveillance System (NEISS) provides information, including consumer product-related information, about injuries leading to emergency room visits. NEISS candle fire injury estimates include injuries from both attended (by the fire department) and non-attended fires. But they only tell about injuries – not fires, deaths, or property loss. The National Residential Fire Survey collects information about fires in households. It tells a part of the story not told by NFIRS/NFPA or NEISS estimates – fires in households even if they aren't attended by the fire department and don't lead to an injury. This candle fire estimate is much larger than the NFIRS/NFPA candle estimate. But there are too few severe fires in the sample to provide accurate information about fire casualties – no candle fire injury or death estimates. These different sets of fire estimates are different pieces to the puzzle of fires and associated losses related to consumer products.

10:30 AM - CNST ELECTRON PHYSICS GROUP SEMINAR: Graphene Transport Properties
Arguably, one of the most intriguing properties of graphene transport is the non-vanishing ``minimum conductivity" at the Dirac point. The carrier density in these single monatomic sheets of carbon can be continuously tuned from electron-like carriers for large positive gate bias to hole-like carriers for negative bias. The physics close to zero carrier density (also called the intrinsic or Dirac region), is now understood to be dominated by the inhomogeneous situation where the local potential fluctuates around zero, breaking the landscape into puddles of electrons and holes. In this talk I will first briefly review (from a theorist's perspective) the competing effects of disorder, electron-electron interactions and quantum interference on graphene's transport properties. I will then compare a fully quantum-mechanical numerical calculation of the conductivity to a semi-classical Boltzmann transport theory and find that while the two theories are incompatible at weak disorder, they are compatible for strong disorder [1]. This result elucidates why the semi-classical self-consistent Boltzmann Random-Phase-Approximation theory for graphene transport [2] is in remarkable agreement with recent experiments [3-4].

1:30 PM - MATERIALS AND CONSTRUCTION RESEARCH DIVISION SEMINAR: Issues in the Flow of Yield-Stress Liquids
The flow of yield-stress liquids has been studied for nearly one hundred years, but major conceptual issues still remain. Yield stress liquids respond as elastic or viscoelastic solids prior to yielding, and they flow as viscous or viscoelastic liquids after yielding. The primary unresolved issue, at least from a simulation perspective, appears to be the description of the mechanics of the yielding phenomenon itself. Classical descriptions of yield stress fluids assume that yielding is a reversible process that occurs at an invariant surface in stress space, and certain general conclusions regarding flow structure and symmetries in the yielded regime follow. This description is sometimes inadequate to describe real fluids, however, where a thixotropic response caused by disruption of the microstructure following the initiation of flow may result in dissipative motion at stresses below the nominal yield stress.

10:30 AM - NIST COLLOQUIUM SERIES (JOINTLY SPONSORED BY MSEL): Pores Without Walls for Clean Energy
The ability to stitch molecules into extended porous structures (reticular chemistry) is a new area of research that has enabled the design of metal-organic frameworks (MOFs) having surface areas of several football fields per gram (10,000 m2/gm). This internal surface is critically important in applications leading to cleaner fuels and capture of carbon dioxide from power plants. I will present how my love for molecules has led to beautiful creations and applications of a new class of crystalline materials with a diversity and number that far exceed any other.

10:45 AM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Collective Motions and Anharmonicity in Protein Terahertz Response
The presence of structural collective motions in picosecond dynamics is investigated through terahertz (THz) time domain spectroscopy and molecular dynamics simulations of cytochrome c as a function of oxidation and hydration. For both oxidation states the measured THz response rapidly increases with hydration up to ~.25 h, and then saturates above this level. A large increase in the picosecond response occurs with oxidation, with the largest flexibility increase for lowest hydrations and highest frequencies. Quasi-harmonic vibrational modes and dipole-dipole correlation functions are calculated from the molecular dynamics trajectories. The measured hydration dependence is reproduced by the vibrational collective mode density of states demonstrating the existence of these collective motions. The large oxidation dependence is reproduced only by the dipole-dipole correlation function, indicating the contrast raises diffusive motions. This change in flexibility is consistent with structural contrast occurring in the vicinity of buried internal water molecule.

9/15/09 10:30 AM - MSAG SEMINAR: The International System of Units, the SI: Future Changes Planned for the Definitions
Metrology is the science of measurement. Our ability to make reliable measurements of all kinds is essential to science and technology, and to much of our every-day life. It is the responsibility of the National Metrology Institutes (NMIs, such as NIST, NPL, PTB, NMIJ, CSIRO etc.) and particularly the Bureau International des Poids et Mesures (the BIPM) to provide and maintain the International System of Units (the SI) for the world. It is easy to think of this as a trivial operation, but it is not: It is fundamental for the life we wish to lead, as the speaker shall show with examples. The history of the SI will be described, from its inception in 1790 when Louis 16th established a commission to choose units for the world, to the many changes of the last 50 years. The successive definitions of the seven base units, the metre, the second, the kilogram, the ampere, the kelvin, the mole, and the candela, will be described. The metre has been revised four times, from its definition as one ten millionth of a quadrant of the earth (1793), to the distance between the defining scratches on the prototype metre bar (1895), to a multiple of the wavelength of the red krypton atomic line (1960), to the distance light travels in vacuum in a specified time interval (1983, and still the current definition). The second was originally defined astronomically in terms of the period of rotation of the earth, but is now defined as a multiple of the period of the microwave hyperfine transition in the caesium atom. The kilogram was originally defined as the mass of a decilitre of water, but since 1895 it has been – and still is – defined as the mass of the international prototype of the kilogram, made of platinum-iridium, kept at the BIPM. But we know that the prototype kilogram is itself changing in mass. Of the seven base units, at least five will be given new definitions within the next few years.

9/16/09 10:30 AM - CNST ENERGY RESEARCH GROUP SEMINAR: Functional Nanomaterials for Renewable Energy Applications
Recently, the major concern in the United States (U.S.) is the ever rising fuel price, unemployment and global warming. Extensive research is going on to find alternative green fuel sources so that U.S. dependence on imported oil can be reduced. The major hopes to satisfy our day-to-day fuel demand come from hydrogen, biofuel, photovoltaic and fuel cell research. Water is a renewable resource and covers almost 75% of planet earth and each molecule of water yields one molecule of hydrogen. It is demonstrated that hydrogen can replace our fossil fuel needs. This is also only one energy source which is sustainable and non-carbon fuel. The other promising quick solutions are to get biofuel from waste materials, biomass, converting sugars into liquid fuels and algal biofuel. In addition to direct production of fuel we also can save fuels by using photovoltaic and advanced battery. As the fuel demand is too high not a single technology can solve the energy problem. We need to bring breakthrough researches in each and every streams of renewable energy. In the mean time we also have to make sure that our environment is not affected by the introduction of these new technologies. So, there is an urgent need to develop new environmentally friendly energy sources and improving energy efficiency in many technologies and processes. This talk targets the development of Energy Materials four major promising areas within energy science: (i) Photoelectrochemical and catalytic hydrogen production, (ii) hydrogen storage materials, (iii) Li-ion battery and (iv) Biofuel production from CO2 and non-food sources. Fabrication and study of functional nanoscale materials, with an emphasis on atomic-level tailoring using electrochemical methods to achieve desired properties and functions will be discussed. The flexibility in electrochemical methods for manipulation and structuring of desired materials at the nanoscale level opens up new possibility for revolutionary energy materials. References: S.K.

9/18/09 1:30 PM - CNST ELECTRON PHYSICS GROUP SEMINAR: MANIPULATION OF ULTRA COLD ION BUNCHES WITH TIME DEPENDENT FIELDS
Many state-of-the art applications that use ion sources, like focused ion beam systems designed to drill and mill on the nanometer level, are limited by the energy spread of existing ion sources. We are working on a new source concept[1][2], based on near-threshold ionization of laser cooled atoms inside a magneto optical trap (MOT), to improve this. We have achieved much lower longitudinal energy spreads (0.02 eV) compared the current industry standard Gallium liquid-metal ion sources [3]. Due to the very low initial temperature, extracting at voltages down to several volts is possible. This makes it feasible to manipulate the ions bunches with time dependent electric fields while they are still in the accelerator. We will present measurements done with different kinds of time dependent electric fields that show they can be used to reduce the energy spread even more. Additionally we show they can be used to create a focusing lens. [1] J.L. Hanssen et al, Phys. Rev. A 74, 063416 (2006). [2] S. B. van der Geer et al, J. Appl. Phys. 102, 094312 (2007) [3] M. P.

9/21/09 10:30 AM - CNST ENERGY RESEARCH GROUP SEMINAR: Electrochemical Studies on Pt-modified Metal (M) Bimetallic Electrocatalysts
Electrocatalytic activities of Pt-modified M (M = Ru, Au) bimetallic catalysts were prepared in terms of a surface modification strategy were investigated towards methanol (MeOH) electro-oxidation, carbon monoxide (CO) oxidation and oxygen reduction reaction (ORR). By experimentally controlling the Pt coverage on the metal substrates via a spontaneous deposition method, the resulting Pt-modified Ru or Au substrates indicated Pt coverage-dependent electrochemistry. Most importantly, it was observed that the inactivity of Pt towards MeOH oxidation with very low coverage and, the emerging and increasing activity with increasing coverage coincided with the phenomena predicted by the ensemble effect, a hypothesis that has not yet supported directly by experimental evidence. Later a one-pot wet chemistry method was developed to prepare Pt-decorated Ru nanoparticles with a submonolayer of Pt. The electrochemical characterization of the whole series of samples provided experimental evidence that strongly supported a bifunctional mechanism, rather than an electronic effect as the dominant factor contributing to the enhanced CO tolerance. Finally, using a core(Au)/shell(Pt) model, a detailed investigation of electrocatalytic properties of Au@Pt nanoparticles was performed as a function of the Pt shell packing density and Au core size. It was observed that the electrochemical behavior of Pt quite much deviated from its bulk counterpart especially at low coverage. The data obtained so far indicated that the future of PtAu as an anode electrocatalyst for MOR is questionable.

9/25/09 10:30 AM - NIST COLLOQUIUM SERIES: From Nature and Back Again - Giving New Life to Materials for Energy, Electronics, Medicine and the Environment
This talk will describe conditions under which organisms first evolved to generate materials and then discuss how one might move beyond naturally evolved materials to genetically imprint advanced technologies. Organisms have been making exquisite materials for over 500 million years, but the types of materials that organisms have evolved to work with are limited. However, there are many properties of living systems that could be harnessed to make advanced technologies that are smarter, more adaptable, and more compatible with the environment. One approach is to evolve organisms to work with a more diverse set of building blocks and design them to address electronic, military, medicine, and energy applications. Examples include a virus-enabled lithium ion rechargeable battery and materials for solar and display technologies.

RESEARCH INVOLVING HUMAN SUBJECTS
Individuals at NIST who wish to conduct, or wish to sponsor, any research involving human subjects, including human cells or tissue, are required by Federal regulations to obtain approval before embarking on the research. This includes: (1) Research conducted here at NIST by NIST employees or guest workers; (2) Collaborative research with others outside of NIST, including CRADAs and other agreements; and/or (3) Research funded by NIST through grants, contracts, or cooperative agreements. The current procedures for approving projects involving human subjects can be found in the NIST Administrative Manual Subchapter 14.01, Protection of Human Subjects (http://www-i.nist.gov/admin/mo/adman/1401.htm). These procedures ensure that the proposed research is in compliance with the applicable DOC Regulations, 15 C.F.R. Part 27 (http://www.access.gpo.gov/nara/cfr/waisidx_99/15cfr27_99.html). NIST's Institutional Review Board (IRB) reviews and approves those research proposals involving human subjects that require IRB review for research to be conducted by NIST employees, with or without the participation of others. The NIST IRB is described in Administrative Manual Subchapter 3.01, Appendix A (http://www-i.nist.gov/admin/mo/adman/301irb.htm). These regulations are broader than many people realize, and involve more than, for example, just invasive medical procedures. They can also cover volunteers participating in questionnaires and surveys and people testing computer software. All research involving human subjects being conducted at an institution outside of NIST that has not been determined to be exempt from the Federal policy by the appropriate NIST OU Director must be approved by a cognizant IRB that is currently registered with the Office for Human Research Protections (OHRP), DHHS. In addition, the institution conducting the research involving human subjects must have a current Federalwide Assurance (FWA) on file with OHRP. The outside IRB's approval will be subject to review and approval by NIST. The NIST IRB Chair reviews the documentation provided by the outside researchers and the outside IRB and recommends approval or disapproval to the NIST Deputy Director, with the concurrence of the Chief Counsel for NIST. Research being conducted at NIST by NIST employees that has not been determined to be exempt by the appropriate NIST OU Director must be reviewed by the NIST IRB. The use of human subjects in the project may not begin until the Chief Counsel for NIST has concurred with the IRB's recommendation to approve the project and the Deputy Director of NIST has approved it. Signatures required before the proposal is sent to the NIST IRB include that of the Group Leader and Division Chief (who approve the scientific merit of the research), and the Laboratory Director (who determines whether it is exempt or requests IRB review). An OU Director's exemption determination must receive concurrence from the Chief Counsel for NIST and then be forwarded to the NIST IRB Chair, Dr. Richard R. Cavanagh, for noting and filing. For more information, contact the NIST IRB Secretary, Janet Brumby, (301) 975-3189 or email: brumby@nist.gov or visit our website at: http://www-i.nist.gov/director/IRB/ (For best viewing of all pages associated with this website, your monitor should have a display setting of 800 by 600 and in Microsoft Internet Explorer).
