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 ...

New fundamental physics research provides insights on the process of diffusion in complex systems such as living organisms. This new theoretical framework has broad implications for active surfaces, ...

A drop of food coloring slowly spreading in a glass of water is driven by a process known as diffusion. While the mathematics of diffusion have been known for many years, how this process works in ...
