QOD Standalone Users Guide

December 16, 2009
Author(s)
Julien C. Cuvillier, Katherine C. Morris
This report describes installation and use of the XML Schema Quality of Design Standalone testing system, or QOD Standalone. QOD Standalone is one of several tools produced by NIST's XML Testbed project within the Manufacturing Systems Integration Division

Architecture and Dynamics of C18 Bonded Interphases with Small Molecule Spacers

December 15, 2009
Author(s)
Lane C. Sander, Katrice A. Lippa, Catherine A. Rimmer, Maximilian Kuhnle, Volker Friebolin, Klaus Albert
The relationship between alkyl phase structure and chromatographic performance is investigated for a series of octadecyl (C18)- modified silica surfaces with defined spacing of the alkyl surface by a “pre-endcapping” technique. Stationary phases were

Effect of Diamond Nanolubricant on R134A Pool Boiling Heat Transfer

December 15, 2009
Author(s)
Mark A. Kedzierski
This paper quantifies the influence of diamond nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a roughened, horizontal, flat surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based

Nanoelectronic Fabrication with Flip Chip Lamination

December 15, 2009
Author(s)
Mariona Coll Bau, Curt A. Richter, Christina Hacker
Nanoelectronic fabrication with Flip chip lamination Mariona Coll, CA Richter, CA Hacker, Colloquium Catalan Institute of Nanoscience and Nanotechnology CIN2, Barcelona Spain, Dec 2009.

The Science of Interaction

December 15, 2009
Author(s)
Theresa O'Connell, John Stasko, John Dill, William Pike, Alan MacEachren
There is a growing recognition within the visual analytics community that interaction and inquiry are inextricable. It is through the interactive manipulation of a visual interface the analytic discourse that knowledge is constructed, tested, refined, and

Ultrafast Demagnetization Dynamics at the M Edges of Magnetic Elements Observed Using a Tabletop High-Harmonic Soft X-Ray Source

December 15, 2009
Author(s)
Thomas J. Silva, Justin Shaw, Hans Nembach, Chan La-O-Vorakiat, Mark Siemens, Margaret M. Murnane, Henry C. Kapteyn, Stefan Mathias, Martin Aeschlimann, Patrik Grychtol, Roman Adam, Claus M. Schneider
We use few-femtosecond soft x-ray pulses from high-harmonic generation to extract element-specific demagnetization dynamics and hysteresis loops of a compound material for the first time. Using a geometry where high-harmonic beams are reflected from a

A Structural Approach to the Temporal Modeling of Networks

December 14, 2009
Author(s)
Brian D. Cloteaux, Isabel M. Beichl
Simulation of many dynamic real world systems such as the Internet and social networks requires developing dynamic models for the underlying networks in these systems. Currently, there is a large body of work devoted towards determining the underlying

Marketplace Assessment - Metric Labeling on Packages in Retail Stores

December 14, 2009
Author(s)
Elizabeth J. Benham
Use of metric labeling on United States consumer products has a long history. Currently, the Fair Packaging and Labeling Act (FPLA) requires dual unit labeling, while products regulated by states under the Uniform Packaging and Labeling Regulation (UPLR)

Quantum information processing and quantum control with trapped atomic ions

December 14, 2009
Author(s)
David J. Wineland
The role of trapped atomic ions in the field of quantum information processing is briefly reviewed. We discuss some of the historical developments that enabled ions to enter the field and then summarize the basic mechanisms required for logic gates and the

ThermoML an XML-based Approach for Storage and Exchange of Experimental and Critically Evaluated Thermophysical and Thermochemical Property Data. 4. Biomaterials

December 12, 2009
Author(s)
Robert D. Chirico, Michael D. Frenkel, Vladimir Diky, Robert N. Goldberg, Heiko Heerklotz, John E. Ladbury, David P. Remeta, John H. Dymond, Anthony R. Goodwin, Kenneth N. Marsh, William A. Wakeham
ThermoML is an XML-based approach for storage and exchange of experimental and critically evaluated thermophysical and thermochemical property data. Extensions to the ThermoML schema for the representation of properties of biomaterials are described. The

EXAFS Studies of Catalytic DNA Sensors for Mercury Contamination of Water

December 11, 2009
Author(s)
Bruce D. Ravel, S.C. Slimmer, X. Meng, G.C.L. Wong, Y. Lu
Monitoring of metallic contaminants in domestic and agricultural water systems systems requires technology that is fast, flexible, sensitive, and selective. Recently, metal sensors based on catalytic DNA have been demonstrated as a practical monitoring

Interlaboratory Study of Alternate Filter Papers for Use in ASTM E 2187

December 11, 2009
Author(s)
Richard G. Gann, William F. Guthrie
ASTM E 2187 has become the internationally referenced standard for designing and specifying less fire-prone cigarettes. In this test method, a lit cigarette is laid on multiple layers of filter paper, and the observer identifies whether the cigarette burns

MEMS Parallel Plate Rheometer for Oscillatory Shear Micro Rheology Measurements

December 11, 2009
Author(s)
Gordon Christopher, Nicholas G. Dagalakis, Steven D. Hudson, Kalman D. Migler
Growing numbers of applications including proteomics, cosmetics, and thin film coatings use novel viscoelastic materials that derive their rheological properties from micro scale structure created by the inclusion of long chain molecules, nano particles

Compensation of Field-Induced Frequency Shifts in Ramsey Spectroscopy of Optical Clock Transitions

December 10, 2009
Author(s)
A. V. Taichenachev, V. I. Yudin, Christopher W. Oates, Barber W. Zeb, Nathan D. Lemke, Andrew Ludlow, U Sterr, Ch. Lisdat, F Reihle
We develop a modified version of Ramsey spectroscopy that uses an additional frequency shift to compensate frequency shifts induced by the excitation itself. In its simplest realization, this method uses a small step of the probe frequency during the two

Oersted Field Induced Magnetization Scissoring In Permalloy Bars

December 10, 2009
Author(s)
Lu Yuan, Fabio C. da Silva, Sean Halloran, Hamid Z. Fardi, David P. Pappas
We have systematically studied the magnetization behavior induced by the applied current in the permalloy (Ni81Fe19) bars using second and third harmonic analysis. Three types of sample were studied with layer structures of Al30/NiFe10, NiFe5/Al30/NiFe5
