ThermoML - An XML-Based Approach for Storage and Exchange of Experimental and Critically Evaluated Thermophysical and Thermochemical Property Data 2. Uncertainties

May 26, 2003
Author(s)
Robert D. Chirico, Michael D. Frenkel, Vladimir Diky, K N. Marsh, R C. Wilhoit
ThermoML is an XML-based approach for storage and exhange of experimental and critically evaluated thermophysical and thermochemical property data. Extensions to the ThermoML schema for the expression of uncertainties are described. Basic principles, scope

Gold-Black Coatings for Freestanding Pyroelectric Detectors

May 23, 2003
Author(s)
John H. Lehman, Evangelos Theocharous, George P. Eppeldauer, Chris Pannell
We describe the process of depositing gold-black on thin, freestanding pyroelectric detector substrates and compare this with previous work documented in the literature. We have evaluated gold-black coatings on thin, freestanding pyroelectric detector

Electricity Division Programs, Activities, and Accomplishments

May 21, 2003
Author(s)
James K. Olthoff, Barry A. Bell
This book describes the research programs, activities, and recent accomplishments of the Electricity Division organized by research project. After the project descriptions is a list of the calibration services that the Division provides, NRC Postdoctoral

A Test Shell for Developing Automated Commissioning Tools for BACnet Systems

May 20, 2003
Author(s)
Natascha S. Milesi-Ferretti, Michael A. Galler, Steven T. Bushby
spite advances in building automation technology, many building control systems do not work as intended. Thorough commissioning of control systems can significantly improve operation but it is manually intensive and thus expensive and often neglected

Effects of Hydrolytic Degradation on In Vitro Biocompatibility of Poly (d,l-lactic)

May 20, 2003
Author(s)
S Yoneda, William F. Guthrie, D S. Bright, C A. Khatri, F W. Wang
In order to investigate the effects of hydrolytic degradation on the biocompatibility of poly(d,l-lactic acid) [P(d,l-LA)], the initial attachment of MC3T3-E1 osteoblast-like cells on various degraded P(d,l-LA) disks was assessed. MC3T3-E1 cells were

Cyrogenic pulsed inductive microwave magnetometer

May 15, 2003
Author(s)
Anthony B. Kos, John P. Nibarger, Radek Lopusnik, Thomas J. Silva, Zbigniew J. Celinski
A cryogenic pulsed inductive microwave magnetometer is used to characterize the switching dynamics in thin-film materials at low temperatures and microwave frequencies. The system is contained inside a 20-cm-dia ultrahigh vacuum chamber and cooled by a

Defect Related Switching Field Reduction in Small Magnetic Particle Arrays

May 15, 2003
Author(s)
Michael J. Donahue, G Vertesy, Martha Pardavi-Horvath
An array of 42 m square, 3 m thick garnet particles has been studied. The strong crystalline uniaxial anisotropy of these particles results in the stable remanent state being single domain with magnetization parallel to the film normal. Magnetooptic

Electron Beam Stimulated Spin Reorientation

May 15, 2003
Author(s)
T L. Monchesky, john unguris, Robert Celotta
Using Scanning Electron Microscopy with Polarization Analysis (SEMPA), we observed the electron beam induced switching of the magnetic state of epitaxial single-crystal Fe(110) films grown on atomically flat cleaved GaAs(110). For low film thickness the

High-Frequency Measurements of Spin Valve Films and Devices

May 15, 2003
Author(s)
Shehzaad F. Kaka, John P. Nibarger, Stephen E. Russek, N. A. Stutzke, S. L. Burkett
High-frequency measurements of spin-valve films and devices, made using several different measurement techniques, are presented and compared. Pulsed inductive measurements were made on sheet films and provide insight into the intrinsic dynamical properties

Interfacial Properties of ZrO 2 on Silicon

May 15, 2003
Author(s)
Y S. Lin, R Puthenkovilakam, J Chang, Charles E. Bouldin, Igor Levin, Nhan Van Nguyen, James R. Ehrstein, Ying Sun, P Pianetta, T Conard, Wilfried Vandervorst, V Venturo, S Selbrede

Iron and Permalloy Based Magnetic Monolithic Tunable Microwave Devices

May 15, 2003
Author(s)
Bijoy Kuanr, Leszek Malkinski, Robert E. Camley, Zbigniew Celinski, Pavel Kabos
We constructed a series of Magnetic Monolithic tunable Microwave notch-filters and phase shifters in co-planer waveguide (CPW) geometry on GaAs substrates using Fe and Permalloy as magnetic materials. In contrast to previous work with Molecular Beam

National Institute of Standards and Technology (Handbook Chapter)

May 15, 2003
Author(s)
Joan Hash
The submission is a chapter describing NIST security standards (FIPS and Special Publication series 800). The author's instructions were that NIST prepare chapter summarizing standards indicating title, dates, publications, and brief summaries.

Next Generation Fire Suppression Technology Program: Fy2003 Progress

May 15, 2003
Author(s)
Richard G. Gann
The Department of Defense's Next Generation Fire Suppression Technology Program (NGP) has completed its sixth year of research with a goal to develop and demonstrate technology for economically feasible, environmentally acceptable and user-safe processes

Nucleation and Evolution of Hybrid Spin Spiral in Soft/Hard Ferromagnetic Bilayer

May 15, 2003
Author(s)
Yury P. Kabanov, V S. Gornakov, Valerian I. Nikitenko, Alexander J. Shapiro, Robert D. Shull
The hybrid exchange spring behavior in a bilayer consisting of an epitaxial film of Fe (500 A)/Smu2^}Co 7}(350 A) deposited onto a Cr(200 A) buffered MgO(110) substrate was investigated using the magneto-optical indicator film technique. Two critical

Room Temperature Active Regenerative Magnetic Refrigeration: Magnetic Nanocomposites

May 15, 2003
Author(s)
F Shir, L Yanik, Lawrence H. Bennett, Edward Della Torre, Robert D. Shull
Nanocomposites have several advantages as a refrigerant for 100 -300 K applications, compared to the other common methods of assembling a magnetic refrigeration bed, such as a layered arrangement of the thermal bed or mixing of different magnetic materials
