Diffusion in supercritical fluids characterises the rate at which molecules migrate under concentration gradients in a medium above its critical temperature and pressure. In this regime, fluid density ...

Diffusion plays an important role in various transfer processes ranging from science and technology to multi-agent and social behaviour in wildlife. It plays a decisive role in biological processes ...

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 ...
