Argon I Lines Produced in a Hollow Cathode Source, 332 nm to 5865 nm

April 1, 2002
Author(s)
W Whaling, W H. Anderson, M T. Carle, J W. Brault, H A. Zarem
We report precision measurements by Fourier transform spectroscopy of the vacuum wavenumber, line width, and relative signal strength of 927 lines in the AR I spectrum. Wavelength in air and classification of the transition are supplied for each line. A

BEES 2.0: Building for Environmental and Economic Sustainability Peer Review Report

April 1, 2002
Author(s)
M A. Curran, J G. Overly, P Hofstetter, R Muller, Barbara C. Lippiatt
This report documents the results of a technical review of the BEES (Building for Environmental and Economic Sustainability) 2.0b software and user manual. BEES measures the life-cycle environmental and economic performance of building products using

Biogenic Contributions to Atmospheric Volatile Organic Compounds in Azusa, California

April 1, 2002
Author(s)
George A. Klouda, C. W. Lewis, D C. Stiles, J L. Marolf, W D. Ellenson, W A. Lonneman
An objective of the 1997 Southern California Ozone Study (SCOS97) was to provide an up-to-date assessment of the importance of biogenic emissions for tropospheric ozone production in the South Coast Air Basin. To this end ambient air samples were collected

Carbon: A Bane for Giant Magnetoresistance Magnetic Multilayers

April 1, 2002
Author(s)
D X. Yang, H D. Chopra, B Shashishekar, P J. Chen, William F. Egelhoff Jr.
This study reports the highly deleterious role of small amount of carbon on the structure and magnetic properties of giant magnetoresistance NiO-Co-Cu-based spin valves. Controlled incorporation of 1-3 atomic % carbon in the Co/Cu layers, resulting in the

Co-Extrusion of Biocompatible Polymers for Scaffolds With Co-Continuous Morphology

April 1, 2002
Author(s)
N. R. Washburn, Carl Simon Jr., Alessandro Tona, H M. Elgendy, Alamgir Karim, Eric J. Amis
A methodology for the preparation of porous scaffolds for tissue engineering using co-extrusion is presented. Poly(espilon-caprolactone) is blended with poly(ethylene oxide) in a twin-screw extruder to form a two-phase material with micron-sized domains

Coherent Phase Equilibria in a Bending Film

April 1, 2002
Author(s)
Alexander L. Roytburd, Julia Slutsker
The theory of coherent phase diagrams is expanded to phase transformations in films. Coherent phase transformations in a free standing film or a thin plate are considered. It is suggested that the misfit between the phases dictates their layer arrangement

Combinatorial Materials Science: What's New Since Edison?

April 1, 2002
Author(s)
Eric J. Amis, X D. Xiang, J C. Zhao
Combinatorial methods, or high throughput experimentations, have captured the attention of the materials industry due to the promise of providing new discoveries faster, better, and cheaper. However, in the scientific community combinatorial methods have

Combinatorial Methods for Investigations in Polymer Materials Science

April 1, 2002
Author(s)
J C. Meredith, A P. Smith, A J. Crosby, Eric J. Amis, Alamgir Karim
Combinatorial methods of drug discovery in pharmaceuticals research are well known and more recent applications have led to the discovery and synthesis of new inorganic materials, catalysts, and organic polymers. Polymeric coatings play an important role

Comparison of Near-Infrared Transmittance and Reflectance Measurements Using Dispersive and Fourier Transform Spectrophotometers

April 1, 2002
Author(s)
James J. Butler, H Park, P Y. Barnes, E A. Early, C van Eijk-Olij, A E. Zoutman, S van Buller-Leeuwen, J G. Schaarsberg
A spectrophotometer based on an integrating sphere coupled to a commercial FTIR instrument has been constructed for regular spectral transmittance and reflectance measurements over the 1 m to 18 m wavelength region. Despite the large number of error

Critical Behavior of a Strain Percolation Model for Metals

April 1, 2002
Author(s)
Y Shim, Lyle E. Levine, R M. Thomson
Extensive simulations of a strain percolation model for a deforming metal have been performed to examine its strain behavior. We find that the total strain exhibits critical power-law behavior that is well explained by two-dimensional percolation theory

Designing Neutral-Atom Nanotraps With Integrated Optical Waveguides

April 1, 2002
Author(s)
J P. Burke, S G. Chu, Garnett W. Bryant, Carl J. Williams, Paul S. Julienne
Integrated optical structures offer the intriguing potential of compact, reproducible waveguide arrays, rings, Y-junctions, etc, that could be used to design evanescent field traps to transport, store, and interact atoms in networks as complicated as any

Direct RF to Optical Frequency Measurements With a Femtosecond Laser Comb

April 1, 2002
Author(s)
Scott A. Diddams, D J. Jones, Jun Ye, S T. Cundiff, John L. Hall, J K. Ranka, R S. Windeler
By spanning an optical octave (> 300 THz) with a broadened femtosecond laser frequency comb, we directly measure optical frequency standards at 1064/532nm, 633 nm and 778 nm in terms of the microwave frequency that controls thecomb spacing, which can be

Empirical Modeling Methods Using Partial Data

April 1, 2002
Author(s)
Gerard N. Stenbakken, Ruimin Liu, Gene Huang
Methods were developed to calculate empirical models for device error behavior from data sets with missing data. These models can be used to develop reduced point testing procedures for the devices. The partial data methods reduce the prediction
