2Supercritical fluid extraction — (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent. Extraction is usually from a solid matrix, but can also be from liquids. SFE can be used as a sample …
3Supercritical water oxidation — or SCWO is a process that occurs in water at temperatures and pressures above a mixture s thermodynamic critical point. Under these conditions water becomes a fluid with unique properties that can be used to advantage in the destruction of… …
4Supercritical drying — (red arrow) goes beyond the critical point of the working fluid in order to avoid the direct liquid–gas transition seen in ordinary drying (green arrow) or the two phase changes in freeze drying (blue arrow). Supercritical drying is a process to… …
5Supercritical — may refer to:* Critical mass, the smallest amount of fissile material needed for a sustained nuclear chain reaction * Critical temperature, Tc, the temperature above which distinct liquid and gas phases do not exist * Supercritical fluid, a… …
6Supercritical fluid chromatography — is a form of normal phase chromatography that is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules. It can also be used for the separation of chiral compounds. Principles are similar to those… …
7Supercritical fluid — A supercritical fluid is any substance at a temperature and pressure above its thermodynamic critical point. It can diffuse through solids like a gas, and dissolve materials like a liquid. Additionally, close to the critical point, small changes… …
8Supercritical carbon dioxide — Carbon dioxide pressure temperature phase diagram Supercritical carbon dioxide is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Carbon dioxide usually behaves as a gas in air at STP… …
9Supercritical water reactor — The Supercritical water reactor (SCWR) is a Generation IV reactor concept that uses supercritical water as the working fluid. SCWRs are basically LWRs operating at higher pressure and temperatures with a direct, once through cycle. As most… …
10Supercritical airfoil — it has since been mainly applied to increase the fuel efficiency of many high subsonic aircraft. Research in 1940 by DVL s K. A. Kawalki led to subsonic profiles very similar to the supercritical profiles, which was the basis for the objection in …
