Underpotential Co-Deposition of Cu_subscript(1-x)Pt_subscript(x) Alloys

September 30, 2006
Author(s)
J Mallett, Ugo Bertocci, Erik B. Svedberg, John E. Bonevich, Alexander J. Shapiro, William F. Egelhoff Jr., Thomas P. Moffat
The electrodeposition of Cu_subscript (1-x)Pt_subscript(x) alloys by underpotential co-deposition of Cu with Pt is demonstrated using an H_subscript(2)SO_subscript(4)-CuSO_subscript(4-)PtCl_subscript(4)_superscript(2-) electrolyte. The composition and

Assessment of Access Control Systems

September 29, 2006
Author(s)
Chung Tong Hu, David F. Ferraiolo, David R. Kuhn
Access control is perhaps the most basic aspect of computer security. Nearly all applications that deal with financial, privacy, safety, or defense include some form of access control. In many systems access control takes the form of a simple password

Using Semantic Web Methods to Improve Information Resource Quality

September 29, 2006
Author(s)
John Barkley
The quality of information resources can be improved using Semantic Web methods instead of, or in conjunction with XML and relational database systems. With Semantic Web methods, more of the semantics of an information resource can be made explicit in a

Focus 3D Telemodeling Tool: GUI Design for Iteration 1

September 28, 2006
Author(s)
Matthew L. Aronoff, John V. Messina, Eric D. Simmon
The Focus 3D Telemodeling Tool was designed as a novel graphical interface to data modeling for standards development. This paper describes the design intent for the proposed Graphical User Interface (GUI) of Focus -- how users interact with the system and

NIST Recommended Practice Guide: Fractography of Ceramics and Glasses

September 26, 2006
Author(s)
George D. Quinn
Fractography is a powerful but underutilized tool for the analysis of fractured glasses and ceramics. Fractography can identify the cause of failure and can even provide quantitative information about the loading conditions. The goal of this Guide is to

Role of Core Support Material in Veneer Failure of Brittle Layer Structures

September 26, 2006
Author(s)
Ilja Hermann, Sanjit Bhowmick, Brian R. Lawn
A study is made of veneer failure by cracking in all-ceramic crown-like layer structures. Model trilayers consisting of a 1 mm thick external glass layer (veneer) joined to a 0.5 mm thick inner stiff and hard ceramic support layer (core) by epoxy bonding

Carbon Based Coatings for Thermal Detectors: Laser Damage and Thermal Efficiency

September 25, 2006
Author(s)
Krishna Ramadurai, Laura H. Lewis, Christopher L. Cromer, Roop Mahajan, Katie Hurst, John H. Lehman
The laser damage threshold and absorption efficiency of a variety of carbon based thermal coatings for laser power and energy measurements have been investigated. Carbon based paint, carbon fibers as well as single wall carbon nanotubes (SWCNTs) and

Contamination and Decontamination of Building Plumbing Systems

September 25, 2006
Author(s)
Stephen J. Treado, Mark A. Kedzierski, Stephanie S. Watson, Kenneth D. Cole
The quality of drinking water has always been a subject of interest. In fact, a stable and secure supply of clean drinking water is a hallmark of modern society. Recently, new concerns have arisen regarding the potential occurrence of intentional or

Damage of thermal detector platforms based on metal-carbon nanotube composites

September 25, 2006
Author(s)
Laurence Lewis, Christopher L. Cromer, Krishna Ramadurai, Roop Mahajan, John H. Lehman
Today's standards for laser power and energy measurements are inadequate for tomorrow's high efficiency diode and fiber lasers. To meet this need, a new generation of thermal detector platforms based on carbon nanotubes (CNTs) and metal is being developed

Ideal Gas Database, version 2.0

September 25, 2006
Author(s)
Vladimir Diky, Michael D. Frenkel
The NIST TRC Ideal Gas Database provides information on the most important thermodynamic properties (heat capacities, entropies, enthalpies, Gibbs free energies and enthalpies and Gibbs free energies of formation) of organic and some other compounds in the

ThermoML Opener

September 25, 2006
Author(s)
Chris Muzny, Vladimir Diky, Robert D. Chirico
ThermoML Opener is a software product that allows one to view ThermoML files in Microsoft Excel. It uses XSLT (eXtensible Stylesheet Language for Transformations) technology to translate a ThermoML file into an HTML file suitable for opening by Excel. The

Characterization of Atomic Motions Governing Grain Boundary Migration

September 24, 2006
Author(s)
Hao Zhang, David J. Srolovitz, Jack F. Douglas, James A. Warren
Molecular dynamics simulations were employed to study atomic motion within stationary and migrating asymmetric tilt grain boundaries. We employ several measures of the complexity of the atomic trajectories, including the van Hove correlation function, the
