Diffusion is a fundamental natural phenomenon that can be observed across a wide range of length and time scales. It plays a ...

A drop of dye added to a glass of water undergoes ordinary diffusion. However, when placed on the surface of a foam, the dye spreads differently—diffusion becomes anomalous. An example of this is the ...

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 ...

Physicists at the University of Kaiserslautern in Germany have observed how individual atoms diffuse through a gas for the first time, and how individual collisions between particles affect diffusion.

Researchers show asymmetric diffusion of skyrmions in a structured environment, unveiling a new path towards unconventional ...
