R M. Verkouteren, C E. Allison, S A. Studley, K J. Leckrone
We report a pilot study of high-precision differential isotopic ratio measurements made on replicate samples of pure carbon dioxide using three instruments of identical manufacture. Measurement protocols were designed to explore the effects of sample size

Relative Permittivity and Refractive Index

Michael R. Moldover, K N. Marsh, J M. Barthel, R Buchner
Measurements of the relative electric permittivity (dielectric constant or relative permittivity) e(p,T) and refractive index of fluids n(p,T) as a function of the pressure and the temperature can be used to determine a wide range of thermodynamic

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
