Progress in the Development of a Kinetic Database for Heptane Combustion

March 1, 2003
Author(s)
Wing Tsang
This paper deals with the development of a chemical kinetic database for use in the simulation of heptane combustion. The database consists of the thermodynamic properties of all reactants, intermediates and products and the consequences, in terms of rate

A Phenomenological Droplet Impact Model for Lagrangian Spray Transport

January 1, 2003
Author(s)
P E. DesJardin, Cary Presser, P J. Disimile, J R. Tucker
The overall objective of this research is to gain fundamental knowledge of fire-suppression agent transport in the cluttered environments of aircraft engine nacelles (i.e., hydraulic and electrical lines, mounting brackets, etc.). A new generation of Halon

Arsenic Thermodynamic Data and Environmental Geochemistry

January 1, 2003
Author(s)
D K. Nordstrom, Donald G. Archer
Thermodynamic data are critical as input to models that attempt to interpret the geochemistry of environmentally important elements such as arsenic. Unfortunately, the thermodynamic data for mineral phases of arsenic and their solubilities have been highly

Diffusion Barrier Cladding in Si/SiGe Resonant Interband Tunneling Diodes and Their Patterned Growth on PMOS Source/Drain Regions

January 1, 2003
Author(s)
N Jin, A T. Rice, P R. Berger, P E. Thompson, C Rivas, R Lake, S Sudirgo, J J. Kempisty, B Curanovic, S L. Rommel, K D. Hirschman, S K. Kurinec, P Chi, David S. Simons, S.J. Chung
Si/SiGe resonant interband tunnel diodes (RITD) employing delta-doping spikes that demonstrate negative differential resistance (NDR) at room temperature are presented. Efforts have focused on improving the tunnel diode peak-to-valley current ratio (PVCR)

Secondary Ion Mass Spectrometry Using Cluster Primary Ion Beams

January 1, 2003
Author(s)
John G. Gillen, Albert J. Fahey
At the National Institute of Standards and Technology (NIST) we have a capability for conducting cluster SIMS experiments on both our ion microscope and TOF-SIMS instruments. This paper will review our recent work on cluster ion source development

Copper Oxide Precipitates in NBS Standard Reference Material 482

December 1, 2002
Author(s)
Eric S. Windsor, R Carlton, John G. Gillen, Scott A. Wight, David S. Bright
Copper oxide has been detected in the copper containing alloys of Standard Reference Material (SRM) 482. This occurrence is significant because it represents heterogeneity within a standard reference material that was certified to be homogeneous on a
