Nanocrystal arrested precipitation in supercritical carbon dioxide
Article Abstract:
Flurocarbon-coated silver, iridium, and platinum nanocrystals ranging in size from 20 to 120 A in diameter are synthesized in supercritical (sc)-CO2 by arrested perception from soluble organometallic precursors. The synthesis is performed in a single CO2 phase by reduction with H2 at elevated temperatures ranging from 60 degree to 100 degree Celsius.

CO2 adsorption on alpha-Cr(sub 2)O(sub 3) (1012) surfaces
Article Abstract:
CO2 adsorption is studied on the well-defined Cr(sub 2)O(sub 3) (1012) single-crystal surface to examine the validity of the using CO2 as a probe of surface basicity. The differences ion the coordination makes the heats of adsorption a poor measure of the basicity of surface oxide ions.
