Formation and rheological properties of the supercritical CO2-water pure interface

Article Abstract:

The frictional coefficient determined from the measured CO2 coefficient was compared with the frictional coefficient calculated from the Stokes equation. It was thus concluded that rheological properties of the equilibrated interface vary with CO2 pressure in the range of 50-90 bar, from viscoelastic comportment to a purely elastic behavior, showing a change in the interfacial organization.

Structure of activated complex of CO2 formation in a CO+O2 reaction on Pd(110) and Pd(111)

Article Abstract:

Examinations of CO2 formed during steady-state CO oxidation reactions were performed using infrared (IR) chemiluminescence. The kinetic results reveal that the higher CO coverage at the lower surface temperatures is inferred to be related to the linear activated complex of CO2 formation.

Solute partitioning between the ionic liquid 1-n-butyl-3-methylimidazolium tetrafluoroborate and supercritical CO2 from capillary-column chromatography

Article Abstract:

The solute partitioning between the ionic liquid 1-n-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) and supercritical CO2 (scCO2) is discussed. Distinct shifts in relative retention are produced due to an increase in scCO2 density at a constant temperature.
