The Refprop Database for the Thermophysical Properties of Refrigerants

September 14, 2003
Author(s)
Mark O. McLinden, Eric W. Lemmon, Marcia L. Huber
Property databases are widely used for the design and analysis of refrigeration systems. Version 7 of the NIST REFPROP Reference Fluid Thermodynamic and Transport Properties) database is described. Compared with previous versions, the database includes

Radiolytic Dechlorination of Polychlorinated Biphenyls in Transformer Oil and in Marine Sediment

November 1, 2002

M Chaychian, C A. Jones, Dianne L. Poster, Joseph Silverman, Pedatsur Neta, Robert E. Huie, M I. Al-Sheikhly
Radiolytic dechlorination of PCBs in transformer oil and in marine sediments has been studied. At low PCB concentrations, complete degradation of the PCBs in transformer oil was achieved without degradation of the oil. Addition of an organic base

Distinguishing the Relative Contribution of Fossil Fuel and Biomass Combustion Aerosols Deposited at Summit, Greenland through Isotopic and Molecular Characterization of Insoluble Carbon

September 1, 2002
Author(s)
J F. Slater, Lloyd A. Currie, J E. Dibb, Bruce A. Benner Jr
Although the earth's polar regions are isolated from most industrial activity, combustion-generated particles from both fossil fuel and biomass burning impact the regions. Most efforts aimed at quantifying the input of combustion aerosols at Summit
