From Stable Lasers to Optical-Frequency Clocks

October 16, 2008
Author(s)
John L. Hall, Jun Ye, L -. Ma, J L. Peng, M Notcutt, J D. Jost, A Marian
This is a report on behalf of the World Tema of Stable Laser and Optical Frequency Measurement Enthusiasts, even if most detailed illustrations draw mainly from our work at JILA. Specifically we trace some of the key ideas that have led from the first

FY 1998 Materials Reliability Division Annual Report

October 16, 2008
Author(s)
H I. McHenry
The technical activities of the Materials Reliability Division during Fiscal year 1998 are summarized. The Division has eighteen research projects in five program areas: Metals Processing (3), Ultrasonic Characterization of Materials (9), Electronic

FY 2001 Programs and Accomplishments - Materials for Microelectronics

October 16, 2008
Author(s)
Frank W. Gayle
Today's U.S. microelectronics and supporting infrastructure industries are in fierce international competition to design and produce new smaller, lighter, faster, more functional, and more reliable electronics products more quickly and economically than

Gas-Gas Equilibria - From Van der Waals to Ulrich Franck

October 16, 2008
Author(s)
Johanna Levelt Sengers
The experimental work of Ulrich Franck and his collaborators on phase separation in binary aqueous mixtures of gases at high pressures and temperatures is summarized and placed against the background of the school of Van der Waals, Van Laar and Kamerlingh

Glass Pocket Evolution in Vitreous Bonded Sapphire

October 16, 2008
Author(s)
Jong S. Lee, M K. Kang, Sheldon M. Wiederhorn, B Hockey, J Blendell
This paper discusses the evolution of glass filled pockets formed by the growth of sapphire through polycrystalline aluminum oxide bonded by anorthite glass. During growth, excess glass is entrapped within the sapphire as channels, which, upon annealing

Globalization of Technical and Safety Standards

October 16, 2008
Author(s)
H V. Oppermann
Standards and conformity assessment practices can have a major impact on competitiveness and ease of access to the international market. Even if companies are not currently exporting products, they are likely to experience the impact of standards on their

Guided Data Capture (GDC) Software

October 16, 2008
Author(s)
Vladimir Diky, Robert D. Chirico, R C. Wilhoit, Qian Dong, Michael D. Frenkel
The program provides software tools to ease capture (compilation) of experimental thermodynamic and transport property data from the literature for pure compounds, binary and ternary mixtures, and chemical reactions (including change-of-state and

He 4 Thermophysical Properties: New ab initio Calculations

October 16, 2008
Author(s)
John J. Hurly, J B. Mehl
Since 2000, atomic physicists have reduced the uncertainty of the helium-helium ab initio potential,for example, from approximately 0.6% to 0.1% at 4 bohr and from 0.8% to 0.1% at 5.6 bohr.These results led us to: (1) construct a new interatomic potential

High Order Shape Functions for Finite Element Analysis

October 16, 2008
Author(s)
Frederick R. Phelan Jr.
A formalism for high-order shape functions used in finite element analysis is developed. The formalism allows the shape functions to be conveniently expressed in terms of their polynomial order p, and their derivative level k. The formalism is verified by

High Temperature Light Scattering of Synthetic Polymers: A Practice Guide

October 16, 2008
Author(s)
Charles M. Guttman, J R. Maurey
The characterization of polymeric materials certified as NIST Standard Reference Materials, to provide such standards to science and industry, has continued at the NIST over an interval of four decades. Characterization of polyethylene SRM's by high

High-Energy Components of Designer Gasoline and Designer Diesel Fuel I. Heat Capacaties, Enthalpy Increments, Vapor Pressures, Critical Properties, and Derived Thermodynamic Functions for Bicyclopentyl Between the Temperatures 10 K and 600 K.

October 16, 2008
Author(s)
Robert D. Chirico
Measurements leading to the calculation of the standard thermodynamic properties for gaseous bicyclopentyl (Chemical Abstracts registry number [1636-39-1] are reported. Experimental methods include adiabatic heat-capacity calorimetry, comparative

High-Temperature, Tensile, Constitutive Data for World Trade Center Steels

October 16, 2008
Author(s)
William E. Luecke, Stephen W. Banovic, Joseph D. McColskey
This paper reports high-temperature tensile constitutive data for nine steels recovered from the fire and impact floors of the World Trade Center. Microstructurally, the nine steels represent typical structural steels from the 1970s. It reports the true
