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 fluids are crucial to understand giant planets such as Jupiter and Neptune, where similar states of matter may reign. A study now published in Nature Communications brings remarkable ...

What is the Stokes-Einstein Equation? The Stokes-Einstein equation is a fundamental relation in physics that describes the diffusion of spherical particles through a fluid with low Reynolds number. It ...

Physicists have observed sound waves moving through a 'perfect' fluid. The results should help scientists study the viscosity in neutron stars, the plasma of the early universe, and other strongly ...
