In-Situ Torque Magnetometry: Magnetic Coupling in Fe/Cr/Fe Thin-Film Systems

October 31, 2008
Author(s)
Dong-Hoon Min, S. B. Lee, John M. Moreland
We have developed an ultra-sensitive torque magnetometer tailored to the study of thin-film interface magnetism and interlayer magnetic exchange coupling. The magnetometer was composed of an optical-fiber interferometer and a customized silicon cantilever

MATERIALS SCIENCE: Nanoscale Polymer Processing

October 31, 2008
Author(s)
Christopher L. Soles, Yifu Ding
Plastics are ubiquitous in our modern world. It difficult to find a manufactured object that does not contain at least some sort polymeric (plastic) components. This ubiquity, in large part, reflects the ease with which polymers can be formed at low

NIST BusiBEES METRICS AND TOOLS FOR GREEN BUILDINGS

October 31, 2008
Author(s)
Barbara C. Lippiatt, Jennifer Helgeson
Building stakeholders need compelling metrics, tools, data, and case studies supporting major investments in sustainable building technologies. Proponents of green building widely claim these buildings to be cost-effective, but often these claims are based

Standardization of 68Ge/68Ga using three liquid scintillation counting-based methods

October 31, 2008
Author(s)
Brian E. Zimmerman, Jeffrey T. Cessna, Ryan P. Fitzgerald
A solution containing 68Ge in equilibrium with its daughter, 68Ga, has been standardized for the first time at the National Institute of Standards and Technology using 3 liquid scintillation- based techniques: live-timed 4pb-g anticoincidence (LTAC)

Surviving the Transition

October 31, 2008
Author(s)
Kristian Helmerson
Observations of the birth of a superfluid have uncovered details of the microphysics of phase transitions. Whether these results can be used to model such trnsitions in the early Universe is an open question.

METRICS TO SUPPORT INFORMED DECISION MAKING FOR CONSUMERS OF BIOBASED PRODUCTS

October 30, 2008
Author(s)
Barbara C. Lippiatt, Marvin Duncan, Zia Haq, Roger Conway
As public policy initiatives, coupled with growing consumer interest have raised the level of interest in the bioeconomy, the question of the appropriate criteria to use in selecting bioproducts, including biofuels, and evaluating their environmental and

UV pulse response nonlinearity of two Si photodiodes

October 30, 2008
Author(s)
Shao Yang, Darryl A. Keenan, Marla L. Dowell
We measured the pulse response nonlinearity of two silicon photodiodes at 193 and 248 nm with different measurement conditions. We found large and different nonlinearities. We discuss the cause of the nonlinear features.

Contribution of Gas and Electric Stoves to Residential Ultrafine Particle Concentrations between 2 nm and 64 nm: Size Distributions and Emission and Coagulation Rates

October 29, 2008
Author(s)
Lance L. Wallace, Wang Fang, Cynthia H. Reed, Andrew K. Persily
Three indoor sources of ultrafine particles (a gas stove, an electric stove, and an electric toaster oven) have been studied in an instrumented test house on the campus of the National Institute of Standards and Technology (NIST). Previous studies have

Reasoning in Manufacturing Part-Part Examples with OWL 2

October 29, 2008
Author(s)
Nenad Krdzavac, Conrad E. Bock
This report examines whether the Web Ontology Language 2 (OWL 2) is expressive enough for some common manufacturing examples involving relations between parts of composite or assembled objects (part-part relations). We specify the semantics of these

Vulnerability Scoring for Security Configuration Settings

October 29, 2008
Author(s)
Karen A. Scarfone, Peter M. Mell
The best-known vulnerability scoring standard, the Common Vulnerability Scoring System (CVSS), is designed to quantify the severity of security-related software flaw vulnerabilities. This paper describes our efforts to determine if CVSS could be adapted

TRC Thermodynamic Tables - Hydrocarbons, Supplement H-136

October 27, 2008
Author(s)
Michael D. Frenkel
1. Table 23-2-(5.12003)-db - Pages db-2610.0 through db-2610.12: New table for 1-butene containing the density for the real fluid at selected temperatures and pressures. 2. Table 23-2-(33.23340)-db - Pages db-3438.0 through db-3438.2: New table for 1

A microfabricated photonic magnetometer

October 26, 2008
Author(s)
Jan Preusser, Vladislav Gerginov, Svenja A. Knappe, John E. Kitching
An integrated optically-controlled sensor, suitable for remote, high-sensitivity detection of magnetic fields is presented. The sensor head is free of electrical currents or metal parts, therefore eliminating distortion of the magnetic fields to be

Structural and magnetic phase diagram of CeFeAsO1- xFx and its relation to high-temperature superconductivity

October 26, 2008
Author(s)
Jun Zhao, Qingzhen Huang, Clarnia dela Cruz, Shiliang Li, Jeffrey Lynn, Ying Chen, Mark Green, G. F. Chen, Z. C. Li, J. L. Luo, N. L. Wang, Pengcheng Dai
Recently, high-transition-temperature (high-Tc) superconductivity was discovered in the iron pnictide RFeAsO1−xFx (R, rare-earth metal) family of materials. We use neutron scattering to study the structural and magnetic phase transitions in CeFeAsO1−xFx as

Combinatorial Studies of Ba-Y-Cu-O Films for Coated-Conductor Applications

October 23, 2008
Author(s)
Winnie K. Wong-Ng, Makoto Otani, Igor Levin, Peter K. Schenck, Zhi Yang, Guangyao Liu, Lawrence P. Cook, Ron Feenstra, Wei Zheng, Marty Rupich
Phase relationships in bulk and thin film Ba-Y-Cu-O high-Tc superconductor system were determined at processing conditions relevant for industrial production of coated conductors. Our results demonstrated that the absence of BaY2CuO5 (which has a critical
