Evolution of Refrigerant Application

May 1, 1999
Author(s)
Piotr A. Domanski
The paper reviews the development of chlorofluorocarbon refrigerants, the implemented replacements of ozone-depleting fluids, other considered alternatives, and the prospect for next-generation refrigerants in response to climate change concerns

Extraction of Sheet-Resistance from Four-Terminal Sheet Resistors in Monocrystalline Films Having Non-Planar Geometries

May 1, 1999
Author(s)
Michael W. Cresswell, Nadine Guillaume, Richard A. Allen, William F. Guthrie, Rathindra Ghoshtagore, James C. OwenI II, Z. Osborne, N. Sullivan, Loren W. Linholm
This paper describes methods for the extraction of sheet resistance from V/I measurements made on four-terminal sheet resistors incorporated into electrical linewidth test structures patterned with non-planar geometries in monocrystalline silicon-on

Face-Centered Cubic Titanium: An Artifact in Titanium/Aluminum Multilayers

May 1, 1999
Author(s)
John E. Bonevich, D van Heerden, Daniel Josell
The present investigation is the first comprehensive comparative study of x-ray diffraction (XRD) and transmission electron microscopy (TEM) results to address the important issue of fcc Ti formation in nanoscale multilayers Ti/Al multilayers with 7.2 and

High-Dimensional Empirical Linear Prediction (HELP) Toolbox User's Guide, Version 2.2

May 1, 1999
Author(s)
Andrew D. Koffman, T. M. Souders, Gerard N. Stenbakken, Hans Engler
This user's guide will assist software users in the understanding of the theory and procedures underlying the High-dimensional Empirical Linear Prediction (HELP) Toolbox, developed for use with the MATLAB(r) mathematical software environment. The HELP

Internal Friction and Creep-Recovery in Indium

May 1, 1999
Author(s)
H M. Ledbetter, N Sizova, Sudook A. Kim, H Kobayashi, S Sgobba, L Parrini
Using low-stress pseudoshear deformation, we measured the ambient-temperature creep-recovery behavior of polycrystalline indium.

Measurement of P-Wave Threshold Law Using Evaporatively Cooled Fermionic Atoms

May 1, 1999
Author(s)
B. L. DeMarco, J L. Bohn, J P. Burke, M J. Holland, Deborah S. Jin
We have measured independently both s-wave and p-wave cross-dimensional thermalization rates for ultracold 40K atoms held in a magnetic trap. These measurements reveal that this fermionic isotope has a large positive s-wave triplet scattering length in

Measurements and Predictions of Light Scattering by Coatings

May 1, 1999
Author(s)
Theodore V. Vorburger, Egon Marx, M E. McKnight, Maria Nadal, P Y. Barnes, Alan Keith Thompson, Michael Galler, Fern Y. Hunt, Mark R. VanLandingham
We show comparisons between calculations and measurements of angle-resolved light scattering distributions from clear dielectric, isotropic coatings. The calculated distributions are derived from topography measurements performed with scanning white light

Migdall Responds

May 1, 1999
Author(s)
Alan L. Migdall
I thank Duane Jaecks for pointing out earlier origins of the first of the correlated photon metrology applications described in my article - absolute detector quantum efficiency. The work in these early references is helpful in putting the technique in a

Modelling Service Life and Life-Cycle Cost of Steel-Reinforced Concrete

May 1, 1999
Author(s)
G J. Frohnsdorff
The NIST / ACI / ASTM Workshop on Modelling Service Life and Life-Cycle Cost of Steel-Reinforced Concrete was focused on possibilities for developing and standardizing such models, specifically for concrete exposed to chlorides. The report includes
