Standard Reference Material 2100: Fracture Toughness of Ceramics

June 1, 2001
Author(s)
George D. Quinn, K Xu, R J. Gettings, J A. Salem, J Swab
New Standard Reference Material (SRM) 2100 is the first reference material in the world for the property fracture toughness for any class material. The SRM is for ceramic fracture toughness and may be used with any ceramic fracture toughness test method

Structural Ceramics Database (Version June 2001)

June 1, 2001
Author(s)
R G. Munro
An update of the NIST Standard Reference Database Number 30, the Structural Ceramics Database, has been completed. This update, designated here as Version June 2001, increases the number of reference citations from 431 to 731, and increases the number of

Switching Dynamics and Critical Behavior of Standard Problem No. 4

June 1, 2001
Author(s)
Robert McMichael, Michael J. Donahue, Donald G. Porter, J Eicke
We report switching dynamics for uMAG standard problem no. 4, a 500 nm x 125 nm x 3 nm rectangle of material with properties to mimic Permalloy. Siwtching dynamics are calculated for fields applied instantaneously to an initial s-state: Field 1 at 170o and

Taming Active Content

June 1, 2001
Author(s)
Wayne Jansen
The private and public sectors depend heavily upon information technology (IT) systems to perform essential, mission-critical functions. As technology improves to provide new capabilities and features, new vulnerabilities are often introduced as well

The Application of High-Speed CNC Machining to Prototype Production

June 1, 2001
Author(s)
Tony L. Schmitz, Matthew A. Davies, Brian S. Dutterer, J C. Ziegert
To reduce delays in the design and manufacture of a new part, rapid prototyping is often employed to minimize lead times. In this paper, the application of high-speed machining to the production of monolithic, metallic, functional prototypes is discussed

The IMS MISSION Architecture for Distributed Manufacturing Simulation

June 1, 2001
Author(s)
Charles R. McLean, Frank H. Riddick
This paper presents an overview of a neutral reference architecture for integrating distributed manufacturing simulation systems with each other, with other manufacturing software applications, and with manufacturing data repositories. Other manufacturing

The NIST Industrial Thermometer Calibration Laboratory

June 1, 2001
Author(s)
C D. Vaughn, Gregory F. Strouse
The NIST Industrial Thermometer Calibration (ITC) Laboratory provides calibrations of industrial thermometers over the range from 196 C to 550 C. The different types of thermometers include liquid-in-glass (LiG), thermistors, thermocouples (

The Role of Simulation in Strategic Manufacturing

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

Thermodynamic Regulation of Actin Polymerization

June 1, 2001
Author(s)
P S. Niranjan, J G. Forbes, S C. Greer, J Dudowicz, Karl Freed, Jack F. Douglas
A Flory-Huggins-type lattice model of actin polymerization under equilibrium conditions is employed to analyze new spectroscopic measurements for the extent of actin polymerization diameter} as a function of temperature T, salt concentration [KC1], and the

Towards Multiscale Simulations of Filled and Nanofilled Polymers

June 1, 2001
Author(s)
S C. Glotzer, Francis W. Starr
We perform simulations of filled and nanofilled polymers using a combination of molecular and mesoscale simulation techniques. Molecular dynamics simulations provide insight into the effect of a nanoscopic filler on the structure, dynamics, and glass

Transient Application, Recirculating Pool Fire, Agent Effectiveness Screen. Final Report.

June 1, 2001
Author(s)
William L. Grosshandler, Anthony P. Hamins, Jiann C. Yang, Kevin B. McGrattan, Cary Presser
A three-year research effort has been conducted as part of the Next Generation Program (NGP) to develop a laboratory screening device suitable for predicting the behavior of halon alternatives in full-scale fire suppression experiments. Most of the work

Uncertainty of the NIST Low Frost-Point Humidity Generator

June 1, 2001
Author(s)
Gregory E. Scace, Joseph T. Hodges
The NIST Low Frost-point Humidity Generator (LFPG) produces water vapor gas mixtures with mole fractions from approximately 5 nmol/mol to 4 mmol/mol for research, calibration of transfer standards, and testing and development of new humidity

Using Ab Initio Calculations in the CALPHAD Environment

June 1, 2001
Author(s)
Benjamin P. Burton, N Dupin, S Fries, G Grimvall, A F. Guillermet, P Miodownik, W A. Oates, V Vinograd
Previous Ringberg working groups have discussed possible applications of first principles (FP) calculations to CALPHAD modeling, and have considered the problems from neglect of short range order (SRO) in CALPHAD Gibbs energy models [1]. Particular

Validation of Scanning Probe Moire Technique With the CTE of Gold

June 1, 2001
Author(s)
Elizabeth S. Drexler, T A. Winningham
Low expansion materials used in electronic devices require a tool that has a commensurate resolution for measuring deformation, such as the atomic force or scanning probe microscope (SPM). The SPM was evaluated for this purpose by conducting experiments
