Issues in Numerical Simulation of Fire Suppression

April 27, 1999
Author(s)
S R. Tieszen, Amelia R. Lopez
This paper outlines general physical and computational issues associated with performing numerical simulation of fire suppression. Fire suppression encompasses a broad range of chemistry and physics over a lxge range of time and length scales. The authors

Recent Results from the Dispersed liquid Agent Fire Suppression Screen

April 27, 1999
Author(s)
Jiann C. Yang, Michelle K. Donnelly, William L. Grosshandler, N C. Prive
Mosl or the current methods for fire suppression efficiency screening (e.2.. cup burners) are designed for evaluating gaseous fire suppression agents. Potential uses of liquid agents as halon replacements have been recently proposed in several applications

Tropodegradable Halocarbons and Main Group Element Compounds

April 21, 1999
Author(s)
J D. Mather, R E. Tapscott
Although it is not certain that a “drop-in” chemical substitute (as opposed to a new technology) for halons that can be used in normally occupied areas will ever be identified. there are two promising paths to such an agent. The first is to target

Capillary Electrophoretic Determination of Oxalate in Amniotic Fluid

April 20, 1999
Author(s)
B C. Nelson, G F. Rockwell, T Campfield, P O'Grady, R M. Hernandez, Stephen Wise
A capillary electrophoretic (CE) assay for oxalate has been applied to the quantitative determination of free oxalate in amniotic fluid. Indirect absorbance detection of oxalate is accomplished with a chromate-based background electrolyte modified with

NIST Calibration Facility for Display Colorimeters

April 12, 1999
Author(s)
Steven W. Brown, Yoshihiro Ohno
A calibration facility has been developed at the National Institute of Standards and Technology (NIST) to address the need for high accuracy color measurementsof displays. Calibration services tailored to display measuremets are planned for colimeters and

Patterning of Hydrogen-Passivated Si(100) using Ar( 3 P 0,2 ) Metastable Atoms

April 12, 1999
Author(s)
S Hill, C Haich, F Dunning, G Walters, Jabez J. McClelland, Robert Celotta, H Craighead
Patterning of silicon by exposing a hydrogen-passivated Si(100) surface to Ar( 3P 0,2) metastable atoms through a fine grid in the presence of a small backgroundpressure of oxygen is described. Metastable atom impact leads to the formation of a uniform

Doping and Oxidation Effects in Raman Spectra of Manganites

April 10, 1999
Author(s)
V B. Podobedov, A Weber, G U. Dezanneau, S U. Pignard, J U. Kreizel, H U. Vincent
Raman scattering from La yR xMnO 3-δ compounds ( single crystals, ceramics, films) was studied as a function of kind (R) and amount (x) of dopant as well as of oxygen deficit (δ). For x = 0.1 to 0. 55, a nearly linear Raman shift of the Adg^ mode from 240

Preface to Materials Research Society 1999 Proceedings

April 5, 1999
Author(s)
H. R. Huff, Curt A. Richter, M. L. Green, G. Lucovsky
This Materials research society Proceedings contains 81 papers presented at the Ultrathin SiO 2 and High-K Materials for gate Dielectrics Symposium, held April 5-9, 1999, in San Francisco. The symposium was truly international with 34 of the 81 published

The Conversion of SURF II to SURF III

April 2, 1999
Author(s)
Mitchell L. Furst, R M. Graves, A D. Hamilton, L R. Hughey, R P. Madden, Robert E. Vest, W S. Trzeciak, L Greenler, P Robl, D Wahl
The Electron and Optical Physics Division of the Physics Laboratory has operated the Synchrotron Ultraviolet Radiation Facility (SURF) at the National Institute of Standards and Technology (NIST) for over 30 years. Initially operated in a parasitic mode at
