8/18 -- TUESDAY

2:00 PM - CNST NANOFABRICATION RESEARCH GROUP SEMINAR: High Index Contrast Silicon-On-Insulator Photonics: From Practical Limitations to New Opportunities
I will discuss my group's recent work on silicon on insulator (SOI) photonics for on-chip lightwave circuits. Part of the talk will discuss the novelty and future prospects for silicon photonics applications and research from a university researcher's perspective who collaborates with industrial partners in this work. In this work, we show that it is important to consider the effects of disorder which inevitably arises from the limited tolerances of lithography. Disorder effects are much more severe for high index contrast, sub micron scale devices, such as SOI photonics, than in any previous generation of integrated optics. Consequently, we have shown that some proposed applications, such as slow light, are severely impacted. On the other hand, disorder in SOI photonics can also enable the realization of phenomena such as light localization, which may offer new approaches to achieve desired functionality in spite of challenging fabrication and design requirements.

10:00 AM - CNST ENERGY RESEARCH GROUP SEMINAR: Applications of Metal-Organic Frameworks Beyond Hydrogen Storage: Way Beyond...
The unique properties of the novel nanoporous materials known as metal-organic frameworks (MOFs) are attracting much interest from communities concerned with storage of hydrogen and other gases, and also for chemical separations. However, the ordered crystalline structures of MOFs and their unique, structurally flexible, nature create opportunities for their use in technically challenging arenas, such as chemical sensing, radiation detection, nanoparticle synthesis, and nanoscale tuning of properties. This presentation will provide an overview of MOF-related research activities at Sandia National Laboratories and will include recent work in the following areas: 1) MOF adaptation to the surfaces of microcantilevers to create a rapid, reversible chemical sensor; 2) synthesis of MOFs with luminescent linkers to create new scintillators; 3) infiltration of MOFs with metal hydrides to create nanoscale hydrogen storage materials; and 4) Ag@MOF nanocomposites with enhanced Raman scattering. Mark D. Allendorf (Ph.D., inorganic chemistry, Stanford University) is a Distinguished Member of the Technical Staff at Sandia/CA, a Fellow of The Electrochemical Society, and formerly that organization's president. He currently leads efforts at Sandia to develop both the fundamental science and applications of MOF compounds. His research interests include chemical sensing, radiation detection, nanoparticle synthesis, and heterostructures for nanoscale electronics. He has published over 100 articles in peer-reviewed journals and conference proceedings.

10:30 AM - CNST ELECTRON PHYSICS GROUP SEMINAR: INDIVIDUAL ATOMS AND MOLECULES ON INSULATING FILMS STUDIED WITH NONCONTACT AFM
We investigated the charge state switching of individual gold and silver adatoms on ultrathin NaCl films on Cu(111) using a qPlus tuning fork atomic force microscope (AFM) operated at 5 Kelvin with oscillation amplitudes in the sub-Ångstrom regime. Charging of a gold adatom by one electron charge increased the force on the AFM tip by a few piconewtons. Employing Kelvin probe force microscopy (KPFM) we also measured the local contact potential difference (LCPD). We observed that the LCPD is shifted depending on the sign of the charge and allows the discrimination of positively charged, neutral, and negatively charged atoms. Furthermore, we modified AFM tips by means of vertical manipulation techniques, i.e. deliberately picking up known adsorbates, to increase spatial resolution. To study the effect of the atomic tip termination we used different well defined tip terminations to image individual pentacene molecules. We compare our experimental results with density functional theory (DFT) calculations to gain insight on the physical origin of contrast formation on the atomic scale.

8/20 -- THURSDAY

10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: Radiative cascades in charged quantum dots
We measured, for the first time, two photon radiative cascades due to sequential recombination of quantum dot confined electron hole pairs in the presence of an additional spectator charge carrier. Utilizing temporally resolved polarization sensitive intensity correlation measurements we fully characterize these radiative cascades. In particular, we identified, direct, all-optical cascades involving spin blockaded intermediate states, and indirect cascades, in which non radiative relaxation mediates between the radiative ones. From our measurements, spin dephasing rates of same carrier pairs are deduced.

1:45 PM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Work Towards High-throughput and High-resolution Synchrotron Powder Diffraction Data Collection and Medium-throughput Crystallographic Analysis
The 11-BM synchrotron powder diffractometer at Argonne's Advanced Photon Source now offers rapid and easy mail-in access to an instrument that offers resolution unmatched in U.S. (.Q/Q ~ 2×10-4). With both vertical and horizontal focusing and a detection system with twelve perfect crystal analyzers, the diffractometer can collect a superb pattern, suitable for Rietveld analysis, in an hour or less. To handle the large number of users and samples, a metadata management system helps automate all aspects of the facility-user interaction, from user request of sample mounting kits and data collection conditions, through completion of safety paperwork, data merging and retrieval and even sample disposal. Information on the diffractometer is available at http://11bm.xor.aps.anl.gov. Despite new and exciting advances in neutron and synchrotron powder diffraction instrumentation, the software used for crystallographic analysis has not advanced significantly in the last decade, even though there are many opportunities for atomistic modeling from diffraction and other types of data. This talk will also present why we perceive a need for a new package to replace GSAS and EXPGUI and our progress towards that goal.

8/21 -- FRIDAY

10:30 AM - CHEMICAL AND BIOCHEMICAL REFERENCE DATA DIVISION SEMINAR: "Refining Hydrocarbon Oxidation Mechanisms via Isomeric Specific Radical Initiated Chemistry"
Accurate chemical mechanisms for the photochemical oxidation of biogenic hydrocarbons is critical to atmospheric modeling, but uncertainties remain. Traditional laboratory kinetics experiments involve "lumped", non-isomeric selective, measurements and are often unable to address many of the outstanding uncertainties. The primary objective of our work has been to develop and refine novel laboratory approaches to studying the isomer-selected OH-initiated oxidation of biogenic hydrocarbons. We have demonstrated a photolytic approach to preparing specific energy-selected isomers along branched reaction pathways. The talk will highlight our progress, including the identification of new chemistry, and the remaining challenges in developing a molecular level description of oxidation processes related to isoprene chemistry.

8/26/09 10:30 AM - ITL SEMINAR SERIES: Linking Remote Attestation to Secure Tunnel Endpoints
Client-Server applications have become the backbone of the Internet and are processing increasingly sensitive information. We rely on the trustworthiness of remote access services. Common practice is to establish secure tunnels to protect the communication between local and remote processes. Ongoing TCG work examines how to monitor properties of remote systems. What is missing is the link between such properties and the remote tunnel endpoint. I will describe how to link specific properties of a remote system gained through TPM-based attestation to secure tunnel endpoints to counter attacks where a compromised authenticated SSL endpoint relays the TPM-based attestation to another system.

8/26/09 2:00 PM - BIOCHEMICAL SCIENCE DIVISION SEMINAR: Biological Sciences in the 21st Century: Priorities and Opportunities
As we continue to learn about the biosphere we are never far from the elusive quest of discovering the origin of life on Earth and defining the indispensable properties of life. New technologies and emergent interdisciplinary fields - such as Systems and Synthetic Biology – have the potential to provide unique insights into life's essential properties while inspiring the use of natural designs and systems for practical purposes. Exploring the non-solar energy sources sustaining life will enable the development of new biology-based technologies with far-reaching applications for sustainable and renewable energy resources. Earth's climate and life support systems are changing in ways and rates not experienced in recorded human history and today's biology must seek to understand, predict, and adapt to these changes. The future depends upon an interdisciplinary approach to research and education that reaches beyond the science of traditional disciplines to prepare a generation of scientists and educators to communicate science as a way of understanding life and adapting to a changing world.

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).
