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 ...

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 ...

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 ...

A research team lays down the foundation for the expansion of supercritical fluid applications research. A long-lasting non-equilibrium phase coexistence in supercritical fluids has been observed by a ...

It's not a liquid. It's not a gas. It's a supercritical fluid. Although it looks like a liquid, it has unique properties that allow scientists to work with it in ways they can't with liquids.

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 ...

Touch the tines of a tuning fork and it goes silent. Scientists have faced a similar problem trying to harness the strength and conductivity of carbon nanotubes, regarded as material of choice for the ...

We have moved well past fitting stuff onto the head of a pin now. Technology has now advanced so far that you could balance a couple of thousand transistors on one end of your split hair. But we want ...

High-performance liquid chromatography and gas chromatography are tried and true analytical chemistry techniques. However, an underappreciated forerunner, supercritical fluid chromatography (SFC), is ...
