Guidelines for the Development of Abstract Test Suites, Edition 2

August 1, 2001
Author(s)
Allison Barnard Feeney
ISO 10303 is an International Standard for the computer-interpretable representation of product data and for exchange of product data. The objective is to provide a neutral mechanism capable of describing product data throughout their life cycle. This

Heat Feedback to the Fuel Surface in Pool Fires (NIST SP 971)

August 1, 2001
Author(s)
Anthony P. Hamins, S. J. Fischer, Takashi Kashiwagi
A series of measurements designed to investigate the heat feedback in pool fires burning liquid fuels are reported. Such measurements are essential for the development and validation of detailed models which predict the burning rate of liquid hydrocarbons

High Throughput Approach to Crystallization in Thin Films of Isotactic Polystyrene

August 1, 2001
Author(s)
Kathryn L. Beers, Jack F. Douglas, Eric J. Amis, Alamgir Karim
The dependence of the crystallization rate of isotactic polystyrene was measured as a function of film thickness and temperature on films with continuous gradients. The results agreed with literature values obtained on discrete films. This validates the

In Situ Raman Spectroscopic Investigation of Chromium Surfaces Under Hydrothermal Conditions

August 1, 2001
Author(s)
James E. Maslar, Wilbur S. Hurst, Walter J. Bowers Jr., Jay H. Hendricks, M I. Aquino, Igor Levin
Three chromium coupons were exposed to air-saturated water at pressures of ca. 25 MPa and temperatures up to 545 C in an optically accessible flow cell. In situ Raman spectra were collected at different temperatures as the coupons were heated and then

Interferometric Testing of Photomask Substrate Flatness

August 1, 2001
Author(s)
Christopher J. Evans, R E. Parks, L Z. Shao, Tony L. Schmitz, Angela Davies
Conventional interferometric testing of the flatness of photomask blanks is rendered difficult by the long coherence length of the HeNe laser sources typically used in commercially available phase measuring interferometers appropriate for flatness testing

International Study of the Sublethal Effects of Fire Smoke on Survivability and Health (SEFS): Phase 1. Final Report (NIST TN 1439)

August 1, 2001
Author(s)
Richard G. Gann, Jason D. Averill, Kathryn M. Butler, Walter W. Jones, George W. Mulholland, J L. Neviaser, Thomas J. Ohlemiller, Richard D. Peacock, Paul A. Reneke, J R. Hall
Fire smoke toxicity has been a recurring theme for fire safety professionals for over four decades. There especially continue to be difficulty and controversy in assessing and addressing the contribution of the sublethal effects of smoke in hazard and risk

Kinetics of Reaction of Calcium Hydroxide and Fly Ash

August 1, 2001
Author(s)
Joseph J. Biernacki, P J. Williams, Paul E. Stutzman
The alkali activated reaction kinetics of a type-F fly ash with calcium hydroxide (CH) and water has been investigated at temperatures between 25 and 60 C. Thermogravimetric analysis (TGA) was used to determine CH consumption and production of hydrates

Low Angle Grain Boundary Dewetting in Sapphire

August 1, 2001
Author(s)
B Hockey, M K. Kang, Sheldon M. Wiederhorn, J Blendell
The structure and composition of low angle grainboundaries produced in sapphire by a liquid phase sintering process were investigated by conventional and high resolution transmission electron microscopy (CTEM and HRTEM, respectively). Considering the

Low-Temperature Kinetics of Reactions of the OH Radical With Propene and 1-Butene Studied by a Pulsed Laval Nozzle Apparatus Combined With Laser-Induced Fluorescence

August 1, 2001
Author(s)
A B. Vakhtin, S Lee, Dwayne E. Heard, I W. Smith, S R. Leone
The kinetics of the reactions of the OH radical with propene and 1-butene are studied at T = 103 K. The low-temperature environment is provided by a pulsed Laval nozzle supersonic expansion of nitrogen with admixed radical precursor and reactant gases. The

MatML-Materials Markup Language Workshop Report

August 1, 2001
Author(s)
C P. Sturrock, E F. Begley, J G. Kaufman
The MatML - Materials Markup Language Workshop was held at NIST to consider the technical and strategic future of MatML, an extensible markup language for materials data. Following detailed description and illustrations of MatML, the views of various

Measured Performance of Building Integrated Photovoltaic Panels

August 1, 2001
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
The photovoltaic industry is experiencing rapid growth. Industry analysts project that photovoltaic sales will increase from their current $1.5 billion level to over $27 billion by 2020, representing an average growth rate of 25%.(Cook et al. 2000)[1]. To

Molecular Engineering of a Polymer of Tetrameric Hemoglobins

August 1, 2001
Author(s)
C Fronticelli, D Arosio, K M. Bobofchak, G B. Vasquez
We have engineered, a recombinant mutant human hemoglobin, Hb prisca Β(S9C+C112G), which assembles in a polymeric form. The polymerization is obtained through the formation of intermolecular S-S bonds between cysteine residues introduced at position Β9, on
