Single-Integral-Equation Method for Three-Dimensional Scattering

July 1, 2001
Author(s)
Egon Marx
The fields scattered by a homogeneous dielectric or finitely conducting object can be obtained from two tangential vector fields, the components of the electric and magnetic fields, on the interface. We have adapted the single-integral-equation method for

Some Physics and Chemistry of Hot-Wire Deposition

July 1, 2001
Author(s)
Alan Gallagher
Although hot-wire chemical vapor deposition (HWCVD) involves far fewer species than plasma enhanced CVD, I have used some physics and chemistry in the title because less is known than unknown regarding the hot-wire deposition processes, in even pure silane

Spin Spring Behavior in Exchange Coupled Soft and High-Coercivity Hard Ferromagnets

July 1, 2001
Author(s)
Robert D. Shull, Alexander J. Shapiro, V S. Gornakov, Valerian I. Nikitenko, J.S. Jiang, H Kaper, G Leaf, S D. Bader
The magnetization reversal processes in an epitaxial Fe/Sm 2Co 7 structure were investigated using the magneto-optical indicator film technique. The dependence of the magnitude and the orientation of the structure average magnetization have been studied on

Static and Dynamic Properties of Stretched Water

July 1, 2001
Author(s)
P A. Netz, Francis W. Starr, H E. Stanley, M C. Barbosa
We present the results of molecular dynamics simulations of the extended simple point charge (SPC/E) model of water to investigate the thermodynamic and dynamic properties of stretched and supercooled water. We locate the liquid-gas spinodal, and confirm

Strain Percolation: Physical Considerations

July 1, 2001
Author(s)
Lyle E. Levine, R M. Thomson, Y Shim
In previous papers, we have introduced a percolation model for the transport of strain through a deforming metal. In this paper, we review the results from that model, and discuss how the model can be applied to the deformation problem. We summarize the

Superconformal Electrodeposition in Submicron Features

July 1, 2001
Author(s)
Daniel Josell, Daniel Wheeler, W H. Huber, Thomas P. Moffat
Superconformal electrodeposition is explained based on a local growth velocity that increases with coverage of a catalytic species adsorbed on the copper-electrolyte interface. For dilute concentration of the catalyst precursor in the electrolyte, local

Temperature-Dependent Behavior of PbSc 1/2 Nb 1/2 O 3 From First Principles

July 1, 2001
Author(s)
Eric J. Cockayne, Benjamin P. Burton, L Bellaiche
We study the ferroelectric phase transition in PbSc1/2Nb1/2O3 (PSN) using a first-principles effective Hamiltonian approach. Results for PSN with NaCl-type ordering of Sc and Nb on the B sites shows that a Pb-centered effective Hamiltonian is appropriate

The Claisen Rearrangement of an Unusual Substrate in Chorismate Mutase

July 1, 2001
Author(s)
S. E. Worthington, Morris Krauss
The calculated reaction path for an unusual substrate of chorismate mutase (Bacillus.subtilis) is found to be completely comparable to that of the native chorismate. In the unusual substrate, the cyclohexadienyl ring in chorismate is replaced by

The Expanding Role of Simulation in Future Manufacturing

July 1, 2001
Author(s)
Charles R. McLean, Swee K. Leong
Simulation technology holds tremendous promise for reducing costs, improving quality, and shortening the timeto- market for manufactured goods. Unfortunately, this technology still remains largely underutilized by industry today. This paper suggests

The Infrared Spectra of OCS + and OCS - Trapped in Solid Neon

July 1, 2001
Author(s)
C Lugez, Warren E. Thompson, Marilyn E. Jacox
When a Ne:OCS sample was codeposited at approximately 5 K with a beam of neon atoms that were excited in a microwave discharge, the infrared spectrum of the resulting deposit included absorptions which can be assigned to OCS +, OCS -, and one or more dimer

The International System of Units (SI), 2001 Edition

July 1, 2001
Author(s)
Barry N. Taylor
NIST Special Publication (SP) 330 is the United States version of the English text of the definitive international reference on the International System of Units (SI) published by the International Bureau of Weights and Measures (BIPM) on behalf of the

The Significance of Percolation on the Dynamics of Polymer Chains Bound to Carbon Black

July 1, 2001
Author(s)
A Nakatani, R Ivkov, P Papanek, C L. Jackson, H Yang, L T. Nikiel, M Gerspacher
Neutron time-of-flight (TOF) spectroscopy is used to compare the chain dynamics of pure polyisoprene with polyisoprene bound to the surface of various grades of carbon black fillers. The carbon black is compounded into the polyisoprene at various initial

Ultimate Capacities of Low-Rise Steel Frames in Turbulent Wind

July 1, 2001
Author(s)
S Jang, L L. Lu, Fahim H. Sadek, Emil Simiu
This paper is a derivative of G2001-1392, Database-Assisted Wind Load Capacity Estimates for Low-Rise Steel Frames, by Jang, S., et al., intended for publication in the Journal of Structural Engineering.The original paper's abstract was:A comparative study

Ultrastable Laser Array at 633 nm for Real-Time Dimensional Metrology

July 1, 2001
Author(s)
John R. Lawall, J Pedulla, Y LeCoq
We describe a laser system for very high-accuracy dimensional metrology. A sealed-cavity helium-neon laser is offset-locked to an iodine-stabilized laser in order to realize a secondary standard with higher power and less phase noise. Synchronous averaging

What to Expect When You Can Not Start at the Beginning

July 1, 2001
Author(s)
David E. Cypher
This presentation contains background information on the decision to create an Specification and Description Language (SDL) model, a discussion of the development cycle for the product development, a description of the SDL's creation, an explanation on how

X-Ray Scattering and Imaging From Plastically Deformed Metals

July 1, 2001
Author(s)
Gabrielle G. Long, Lyle E. Levine, Richard J. Fields
New ultra-small-angle X-ray scattering (USAXS) facilities at 3rd generation synchrotron sources enjoy an additional 1 to 3 decades of X-ray brilliance over 2nd generation instruments, and can now quantify microstructural features from 3nm to 1.3 m in size

Compensation for Stray Light in Projection Display Metrology

June 30, 2001
Author(s)
Paul A. Boynton, Edward F. Kelley
Electronic projection display specifications are often based on measurements made in ideal darkroom conditions and assume ideal measurement instrumentation. However, not everyone has access to such a facility, and not always will the light-measuring
