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, ...

Researchers in the US and China have shown that diffusion at the atomic scale enables long nanowires of crystalline metals to be fabricated using a single-step moulding technique. The nanomoulding ...
