Building better diffusion models for active systems

In normal circumstances, particles will follow well-established random motions as they diffuse through liquids and gases. Yet in some types of system, this behavior can be disrupted—meaning the diffusion motions of particles ...

Elusive atomic motion captured by electron microscopy

The movement of atoms through a material can cause problems under certain circumstances. Atomic-resolution electron microscopy has enabled researchers at Linköping University in Sweden to observe for the first time a phenomenon ...
