Extraction of rosavin from Rhodiola rosea root using supercritical carbon dioxide with water

, 2009
In this study, a new extraction method for the isolation of rosavin from dried crushed roots of Rhodiola rosea is being developed using supercritical CO2 and water. Rosavin extracts quantitatively and qualitatively were compared to commonly used solvents

Permeation of supercritical CO2 through dense polymeric membranes

, 2019
Supercritical carbon dioxide (scCO2) is used in the food industry as a water-extracting drying agent. Once saturated with water, the scCO2 needs to be regenerated. A promising way of drying scCO2 is by using H2O permeable membranes.

The effect of water density on alkaline water electrolysis performance in superheated, subcritical and supercritical phases

JPhys Energy
This work explores the potential of using high-temperature and high-pressure water for alkaline water electrolysis systems. In particular, we investigated the relationship between electrolyte conductivity vs alkaline salt concentration and water density ...

Transport properties of supercritical methane

Physical Review E
The experimental results on molecular diffusion in supercritical methane in a wide pressure range reported by [U. Ranieri et al., Nat. Commun. 15, 4142 (2024)2041-172310.1038/s41467-024-47961-7] are compared with the theoretical expectations based on the Lennard-Jones model. In the low-pressure low-density limit, the kinetic approach within the Chapman-

Solubility of Cholesterol in Supercritical Carbon Dioxide

, 2004
Supercritical fluid (SCF) extraction offers a good alternative to the current methods of extraction that normally involve the use of organic solvents. To perform this technique it is very important to know the solubility of the drug in the supercritical ...
