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, ...

WASHINGTON, D.C., August 22, 2016 -- Most of us think of diffusion in the context of its scientific definition as the process whereby particles of liquids, gases or solids intermingle and in dissolved ...

In a combination of experiments and theory the diffusion of individual atoms in periodic systems was understood for the first time. The interaction of individual atoms with light at ultralow ...

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 ...

Diffusion models represent one of the key successes in marketing science. We understand a great deal about what influences and shapes within-country diffusion patterns. However, we understand far less ...
