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

Refrigeration Methods for Superconductors

December 1, 2002
Author(s)
Ray Radebaugh
This chapter reviews various methods commonly used for achieving the cryogenic temperatures required of superconducting materials. The problems associated with cryogenic refrigerators (cryocoolers), such as poor reliability, low efficiency, electromagnetic

Structural Basis of Thermostability: Analysis of Stabilizing Mutations in Subtilisin BPN

July 26, 2002
Author(s)
O Almog, David Travis Gallagher, Jane E. Ladner, S Strausberg, Patrick Alexander, Phillip Bryan, G L. Gilliland
The crystal structures of two thermally stabilized subtilisin BPN' variants, S63 and S88, are reported here at 1.8 and 1.9 resolution, respectively. The micromolar affinity calcium-binding site (site A) has been deleted (δ 75-83) in these variants

The IUPAC Chemical Identifier

July 1, 2002
Author(s)
Stephen E. Stein, Stephen R. Heller, Dmitrii V. Tchekhovskoi
The author presented two talks at the IUPAC/CAS conference of Chemical identifiers and XML in Chemistry, on July 1, 2002 in Columbus Ohio. He will be sending powerpoint presentations of these talks, both concerning on-going projects at NIST, to IUPAC for

Chorismate Lyase: Kinetics and Engineering for Stability

January 31, 2002
Author(s)
Marcia J. Holden, M P. Mayhew, David T. Gallagher, V L. Vilker
By removing the enolpyruvyl group from chorismate, chorismate lyase (CL) produces p-hydroxybenzoate (p-HB) for the ubiquinone biosynthetic pathway. We have analyzed CL by several spectroscopic and chemical techniques and measured its kinetic (k cat = 1.7x

Single Pulse Shock Tube

October 1, 2001
Author(s)
Wing Tsang, A. Lifshitz
This chapter is concerned with the use of the single pulse shock tube for studying the mechanisms and rate constants for the decomposition of polyatomic molecules at elevated temperatures. It begins with a discussion of the technique. The requirements and

Temperature Dependence of the Formal Reduction Potential of Putidaredoxin

July 20, 2000
Author(s)
Vytautas Reipa, Marcia J. Holden, M P. Mayhew, V L. Vilker
Putidaredoxin (Pdx), a [2Fe-2S] redox protein of size M r transfers two electrons in two separate steps from the flavin containing putidaredoxin reductase to the heme protein, cytochrome CYP101 in the P450cam catalytic cycle. It has recently come to light

Sicklist Database

October 1, 1999
Author(s)
Russell D. Johnson III
This is a database of problems that arise from using a particular ab initio computational method with a particular molecule. It is intended to serve as a guide to prevent people from wasting resources struggling with known problems and to offer solutions
