A supercritical fluid refers to a state in which the temperature and pressure of a substance exceed its critical point, where no distinction exists between liquid and gas phases. Traditionally, it has ...

Neither gas nor liquid, supercritical fluids exhibit a unique mashup of the properties of both and arise when fluids are pushed to very high temperatures and pressures. Their properties make them ...

Supercritical fluids show certain properties that are used to advantage in chromatographic separations: No liquid/gas phase boundary and therefore no surface tension Solute solubility increases with ...

Using emulsion templating, a versatile method for producing porous materials, Cameron and colleagues at the University of Durham, UK, have developed improved techniques for producing cross-linked ...

Diffusion coefficients in supercritical fluids are critical parameters that characterise mass transport within these unique media. Owing to the tunable density and solvent power of supercritical ...

Supercritical fluid chromatography, or SFC, has been around for decades. During that time, the separation technique has fallen in and out of and back in favor. But it has consistently been relegated ...

Researchers in New York have demonstrated a supercritical diesel fuel-injection system that can reduce engine emissions by 80 percent and increase overall efficiency by 10 percent. Going supercritical ...

The temperature and pressure inside Jupiter range from about -100°c near the edge to about 15,000°c and 50m times the Earth’s atmospheric pressure in the middle. Saturn, Uranus and Neptune are similar ...

University of Salford provides funding as a founding partner of The Conversation UK. When we boil a kettle, we observe what scientists call a phase transition: the water changes from being a liquid to ...

Supercritical Fluid Chromatography (SFC) techniques represent an evolving analytical separation method that harnesses the unique properties of supercritical fluids—predominantly carbon dioxide—to ...
