Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging ...

In the world of research, diffusion is understood as a process in which tiny particles disperse uniformly throughout a gas or liquid. Although these media are made up of individual particles, ...

A series of "states" (dots) connected with "transitions" (lines) in a complex system. Bigger dots correspond to states where more time is spent during simulation, thicker lines for faster transitions.

British biochemist Professor Frederick Sanger was awarded his second Nobel Prize for Chemistry in 1980. He is only the third person to win Nobel Prizes for science in the history of he awards and ...

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.

State-of-the-art techniques make it possible to build a spin-chain quantum simulator based on laser-trapped circular Rydberg atoms. This simulator combines the flexibility of atomic lattices and the ...
