Microstructure-Property Correlations in Industrial Thermal Barrier Coatings

July 1, 2004
Author(s)
A Kulkarni, A N. Goland, H Herman, Andrew J. Allen, J Ilavsky, Gabrielle G. Long, C A. Johnson, J A. Ruud
This paper describes the results from multidisciplinary characterization/scattering techniques employed for the quantitative characterization of industrial thermal barrier coating (TBC) systems used in advanced gas turbines. While past requirements for

NIST Impulse Spectrum Amplitude Measurement Service

July 1, 2004
Author(s)
Nicholas Paulter, Donald R. Larson
The NIST service for measuring the impulse spectrum amplitude of the output of impulse generators is described. The calibration procedures used in this measurement service were recently modified and this reduced both the time for measurement and the

Optical Anisotropy of Nanotube Suspensions

July 1, 2004
Author(s)
Erik K. Hobbie
A semi-macroscopic model of an optically anisotropic absorbing nanotube suspension is derived perturbatively from Maxwell s equations in a dielectric medium. We calculate leading-order expressions for the intrinsic and form contributions to the complex

Phase Field Modeling of Solidification Under Stress

July 1, 2004
Author(s)
Julia Slutsker, Alexander L. Roytburd, James A. Warren, Geoffrey B. McFadden, William J. Boettinger
A phase-field model that includes stress field during non-isothermal solidification of a one-component system has been developed. The model has been applied to solidification and melting of confined spherical volumes. It has been shown that at some

Physical Properties of Water

July 1, 2004
Author(s)
Allan H. Harvey, Daniel G. Friend
This chapter reviews the best current information about the thermophysical properties of the fluid phases of water, focusing particularlyon the way in which water's properties change with temperature and pressure at conditions relevant to high-temperature

Quantifying Uncertainty in Nuclear Analytical Measurements

July 1, 2004
Author(s)
Lloyd A. Currie
This document resulted from a request at an International Atomic Energy Agency Consultants' Meeting. Information is based on a document Foundationsand future of detection and quantification limits prepared for the 1996 Proceedings of the Joint Statistical

Refractometry Using a Helium Standard

July 1, 2004
Author(s)
Jack A. Stone Jr., Alois Stejskal
The refractive index of helium at atmospheric pressure can be calculated from first principles with a very low uncertainty, on the order of 10^-10. Furthermore, the low refractive index of helium puts minimal demands on the pressure and temperature

Report to U.S. Election Assistance Commission

July 1, 2004
Author(s)
Douglas R. White
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

Retrieval Evaluation with Incomplete Information

July 1, 2004
Author(s)
C E. Buckley, Ellen M. Voorhees
This paper examines whether the Cranfield evaluation methodology is robust to gross violations of the completeness assumption (i.e., the assumption that all relevant documents within a test collection have been identified and are present in the collection)

Saturation Molalities and Standard Molar Enthalpies of Solution of Cytidine(cr), Hypoxanthine(cr), Thymidine(cr), Thymine(cr), Uridine(cr), and Xanthine(cr) in H 2 O(1)

July 1, 2004
Author(s)
Yadu D. Tewari, Patrick D. Gery, Mark D. Vaudin, Alan D. Mighell, R Klein, Robert N. Goldberg
Saturation molalities, m(sat) in H 0(I) have been measure for the substances cytidine(cr), hypoxanthine(cr), thymidine(cr), thymine(cr), uridine(cr), and xanthine(cr) by using h.p.l.c. The states of hydration were established by performing Karl-Fischer

Semiconductor Microelectronics and Nanoelectronics Programs

July 1, 2004
Author(s)
Stephen Knight, Joaquin (. Martinez, Michele L. Buckley
The microelectornics industry supplies vital components to the electronics industry and to the U.S. economy, enabling rapid improvements in productivity and in new high technology growth industries such as electronic commerce and biotechnology. The

Strength of Silicon, Sapphire in the Subthreshold Flaw and Glass Region

July 1, 2004
Author(s)
Yeon-Gil G. Jung, Antonia Pajares, R Banerjee, Brian R. Lawn
Strength properties are determined for monocrystalline silicon and sapphire and for soda-lime glass plates containing subthreshold flaws, i.e. flaws without detectable microcracks. Nanoindentations covering a wide range of loads are used to introduce flaws

Summary of ISO/TC 201 Technical Report: ISO/TR 19319: 2003 Surface Chemical Analysis Auger Electron Spectroscopy and X-Ray Photoelectron Spectroscopy Determination of Lateral Resolution, Analysis Area, and Sample Area Viewed by the Analyser

July 1, 2004
Author(s)
Cedric J. Powell
ISO Technical Report 19319 contains information on the determination of lateral resolution, analysis area, and sample area viewed by the analyser in surface analyses by Auger-electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS). This

Synthesis and Characterization of PEG Dimethacrylates and their Hydrogels

July 1, 2004
Author(s)
Sheng Lin-Gibson, S Bencherif, James A. Cooper, S Wetzel, Joseph M. Antonucci, Brandon M. Vogel, F Horkay, N. R. Washburn
Facile synthesis and detailed characterization of photo-polymerizable and biocompatible poly(ethylene glycol) dimethacrylates (PEGDM) and poly(ethylene glycol) urethane-dimethacrylates (PEGUDM) are described. Poly(ethylene glycol)s of various molecular

Test of CD-SEM Shape-Sensitive Linewidth Measurement

July 1, 2004
Author(s)
John S. Villarrubia, Andras Vladar, Michael T. Postek
In a model-based library (MBL) approach to scanning electron microscope (SEM) linewidth measurement, a library of simulation results for a range of lineshapes is searched for a match to the measured image of the unknown line. Compared to standard
