Phase Equilibria of the High Tc Superconductors in the (Bi, Pb) -SR-Ca-Cu-O System

February 19, 2017
Author(s)
Winnie Wong-Ng, Lawrence P. Cook, W Greenwood, Anthony J. Kearsley
Applications of (Bi,Pb)-Sr-Ca-Cu-O phase equilibria include material synthesis, melt processing and single crystal growth. Both liquidus and subsolidus data are of central importance. For the determination of liquidus data, we have used a wicking technique

Phase Relations in Ba-(Nd,Eu,Gd)-Cu-O Coated Conductor Films

February 19, 2017
Author(s)
Winnie Wong-Ng, Igor Levin, Joseph J. Ritter, Lawrence P. Cook, Guangyao Liu, Makoto Otani, Christopher E. Lucas, Shailee P. Diwanji, Ron Feenstra, P Goyal, Mark D. Vaudin
Knowledge of phase relations in thin films of Ba2RCu3O6+x (where R=lanthanides or mixed lanthanides) is needed to guide the processing of coated conductors. High-temperature X-ray diffraction studies of Ba2RCu3O6+x films deposited using the

Phase-Correct Bond Lengths in Crystalline-Ge x Si l-x Alloys

February 19, 2017
Author(s)
Joseph Woicik, K E. Miyano, C A. King, R W. Johnson, J G. Pellegrino, T L. Lee, Z H. Lu
Extended x-ray absorption fine structure performed at the Ge-K edge has determined the Ge-Ge and Ge-Si bond lengths in a series of crystalline-Ge l-x alloys (x [greater than/less than] 0.5) to be compositional dependent. This high-precision measurement was

Planning Buildings that will Last

February 19, 2017
Author(s)
G J. Frohnsdorff, H Davies
In designing a building that will perform reliably over a specified time, a designer needs a vast amount of information about the performance of the available materials and components (hereafter referred to, collectively, as maerials) in the likely service

Plant Spatial Configuration Application Protocol. Edition 2

February 19, 2017
Author(s)
Mark E. Palmer, M Gilbert, B F. Gischer
This document specifies the ISO 10303 application protocol (AP) Edition 2 for the exchange of spatial configuration information of process plants, plant systems and ship systems. This includes shape characteristics, spatial arrangement characteristics, and

Plasma Diagnostic Techniques

February 19, 2017
Author(s)
Eric C. Benck
In order for extreme ultraviolet (EUV) plasma sources to become the next generation lithographic source, significant obstacles still need to be overcome. Improvements in conversion efficiency (CE), plasma stability, and component lifetimes are required

Polarization Dependence of Raman Peak Heights in the Absence of an Analyzer

February 19, 2017
Author(s)
Grady S. White, L M. Braun, M I. Bell
The general expression relating Raman scattering intensity to incident and scattered polarization directions is modified to account for an experimental configuration without an analyzer. This expression, combined with the known polarizability tensors for

Practical Intrinsic-Error Bounds for X-Ray Computed Tomography

February 19, 2017
Author(s)
R D. Spal
Images produced by x-ray computed tomography contain intrinsic error due to the limited spatial resolution of the technique. Two bounds on the mean intrinsic error over a specified region are determined, given only minimal information about the object

Predicting Fracture Resistance of Brittle Crystals

February 19, 2017
Author(s)
Grady S. White, Stephen W. Freiman, Lin-Sien H. Lum
A simple expression is derived relating fracture surface energy to easily measured material properties, i.e., the elastic Young's modulus and the equilibrium atomic plane spacing via a proportionality constant, k. This expression appears to be independent

Predictive chemical kinetic model for lubricant performance: bench testings

February 19, 2017
Author(s)
Stephen M. Hsu, C I. Chen
Bench tests have been used to screen lubricants and additives for industrial fluids in machinery applications for a very long time. As technology becomes more sophisticated in terms of materials, controls, and design, the need for simple, quick, and cheap

Probability Distributions of Extreme Wind Speeds in Thunderstorm Prone Regions

February 19, 2017
Author(s)
Franklin T. Lombardo, Emil Simiu
A recently developed capability allows the routine creation, from National Weather Service Automated Surface Observing System (ASOS) records, of separate sets of extreme non-thunderstorm and thunderstorm wind speeds. Using such records it is possible to

Proceedings of the Automated Steel Construction Workshop June 6-7, 2002

February 19, 2017
Author(s)
Alan M. Lytle, Kamel S. Saidi
The Building and Fire Research Laboratory of the National Institute of Standards and Technology, in cooperation with the American Institute of Steel Construction, sponsored a workshop on automated steel construction on June 6-7, 2002, at the NIST

Protocol for Testing Mattress/Foundation Sets Using a Pair of Gas Burners

February 19, 2017
Author(s)
Thomas J. Ohlemiller
A dual burner apparatus has been developed for the purpose of assessing the flammability of a mattress/foundation combination in a manner that correlates with its real world fire behavior. This document sets out the detailed procedure for employing this
