Characterization of the Skin Orientation of Thermotropic Liquid-Crystalline Copolyester Moldings with Near-Edge X-ray Absorption Fine Structure

May 11, 2006
Author(s)
Robert A. Bubeck, L S. Thomas, S Rendon, W R. Burghardt, A Hexemer, Daniel A. Fischer
The process of injection molding net-shape parts from thermotropic liquid crystalline polymers (TLCPs) results in a skin-core macrostructure. The underlying orientation in the core and the skin may differ both in magnitude and direction. A combination of

Effect of Self-Assembled Monolayer Film Order on Nanofriction

May 11, 2006
Author(s)
S Sambasivan, S Hsieh, Daniel A. Fischer, Stephen M. Hsu
Self-assembled monolayers (SAMs) have increasingly being explored as potential protective films in devices friction and adhesion. However, accurate determination of the nanomechanical properties of monolayer films is difficult and fraught with

Probing the Ordering of Semiconducting Fluorene-Thiophene Copolymer Surfaces on Rubbed Polyimide Substrates by Near-Edge X-Ray Absorption Fine Structure

May 11, 2006
Author(s)
L R. Pattison, A Hexemer, E. J. Kramer, Sitaraman Krishnan, P Petroff, Daniel A. Fischer
The temperature-dependent alignment of semiconducting liquid crystalline fluorene-thiophene copolymer (F8T2) thin film surfaces was investigated using the near-edge X-ray absorption fine structure (NEXAFS) technique. Partial electron yield spectra were

A Two-Dimensional Terahertz Imaging System Using Hot Electron Bolometer

May 10, 2006
Author(s)
Dazhen Gu, Eyal Gerecht, Fernando Rodriquez Morales, Sigfrid Yngvesson
We present first results with a two-dimensional(2D)scanning, terahertz passive heterodyne imaging system currently under development. The imager is based on a phonon-cooled quasi-optically coupled HEB mixer integrated with an InP MMIC IF low-noise

Virtual Testing of Cement and Concrete

May 10, 2006
Author(s)
Dale P. Bentz, Edward J. Garboczi, Jeffrey W. Bullard, Chiara F. Ferraris, Nicos Martys, Paul E. Stutzman
Concrete is a unique multi-phase, random, complex, and composite material that provides both strength and impermeability to engineered structures. Unlike most construction materials, the properties of concrete continue to develop over time and in place an

High resolution analysis of the 26 and 2 9 9 bands of propane

May 8, 2006
Author(s)
Jean-Marie Flaud, Walter J. Lafferty, F. Kwabia Tchana
Using high-resolution Fourier transform spectra of propane recorded in the 13.4 μm (resolution of 0.002 cm-1) and in the 27.4 μm (resolution 0.0011 cm-1) spectral regions, it was possible to perform a thorough assignment of both the ν26 band at 745 cm-1

Resolved Torsional Splitting in the nu 18 and nu 19 Bands of Propene

May 8, 2006
Author(s)
Walter J. Lafferty, J.- M. Flaud, M Herman
FT-jet spectra of propene were recorded at 0.005 cm-1 instrumental resolution around 950 cm-1. Thanks to the jet conditions, probably corresponding to Trot close to 80 K, the torsion degrees of freedom are efficiently cooled down and the fine structure of

The Role of LORAN Timing in Telecommunications

May 8, 2006
Author(s)
Michael A. Lombardi, Chuck Norman, William J. Walsh
The telecommunications industry in the United States has performance requirements for time synchronization and frequency control that must be met in order for land and mobile telephone services, wireless networks, and other applications to remain

Quantum Dot Dissemination and Behavior in Bacterial Biofilms

May 7, 2006
Author(s)
Jayne B. Morrow, Richard D. Holbrook, Cynthia J. Zeissler
Quantum dots (QDs) are colloidal semiconductor nanocrystals that photoluminescence emission is proportional to the dot size and have been utilized in fluorescent imaging in biological systems. Biofilms are communities of microorganisms attached to surfaces

The Rich Transcription 2006 Spring Meeting Recognition Evaluation

May 4, 2006
Author(s)
Jonathan G. Fiscus, Jerome G. Ajot, Martial Michel, John S. Garofolo
This paper presents the design and results of the Rich Transcription Spring 2006 (RT-06S) Meeting Recognition Evaluation. This evaluation is the fourth in a series of community-wide evaluations of language technologies in the meeting domain. For 2006

Thermal, Structural, and Optical Properties of Multispectral Zinc Sulfide

May 4, 2006
Author(s)
L Henneman, L LaCroix, C Wilson, S Kurzius, D C. Harris, M Baronowski, B Burns, K Kitagawa, J Gembarovic, S Goodrich, Leonard Hanssen, Simon G. Kaplan, C Staats, J Mecholsky
Lockheed Martin Space Systems Company (LMSSC) and Vicus Technologies have conducted a study to obtain the thermal, structural and optical property data required to predict the flight performance of Multispectral Zinc Sulfide (MS ZnS) windows. The Naval Air

All-Optical Generation and Photoassociative Probing of Sodium Bose-Einstein Condensates

May 2, 2006
Author(s)
R Dumke, M Johanning, Eduardo Gomez, J D. Weinstein, Kevin Jones, Paul D. Lett
We demonsatrate an all optical technique to evaporatively produce sodium Bose-Einsteincondensates (BEC). We use a crossed-dipole trap formed from light near 1 $\mu$m, and a simple ramp of the intensity to force evaporation. In addition, we introduce

Comparison of Photovoltaic Module Performance Measurements

May 2, 2006
Author(s)
Arthur H. Fanney, Mark W. Davis, Brian P. Dougherty, D L. King, W E. Boyson, J A. Kratochvil
Computer simulation tools used to predict the energy production of photovoltaic systems are needed in order to make informed economic decisions. These tools require input parameters that characterize module performance under various operational and

Consumer Package Labeling Guide: Selling by Length and Area

May 2, 2006
Author(s)
K M. Dresser
[Withdrawn (February 12, 2018)] Guide is intended to provide manufacturers, packers, distributors, and retailers of packaged products with information about the labeling requirements for commodities that are sold by length and area in the consumer
