Electrodeposition from supercritical fluids
Physical Chemistry Chemical Physics, 2014 Recent studies have shown that it is possible to electrodeposit a range of materials, such as Cu, Ag and Ge, from various supercritical fluids, including hydrofluorocarbons and mixtures of CO2 with suitable co-solvents. In this perspective we discuss the relatively new field of electrodeposition from supercritical fluids.

Advances in supercritical fluid chromatography [PDF]
Analytical Science Advances, 2021 More than a century ago researchers recognized the unique properties that inorganic gases have above their critical point. Since then, different gases and liquids have been investigated. It was Ernst Klesper who reported on the very first chromatographic separations that used a supercritical fluid as the mobile phase back in 1962. In a brief report, he
