New theory could lead to better batteries, fuel cells

A new theory could enable researchers and industry to tune and improve the performance of a material called ionic ceramics in rechargeable batteries, fuel cells and other energy applications.

Physicists observe the emergence of collective behaviour

Phase transitions describe dramatic changes in properties of a macroscopic system—like the transition from a liquid to a gas. Starting from individual ultracold atoms, Heidelberg University physicists were able to observe ...

Self-cleaning, anti-reflective, microorganism-resistant coatings

Coatings or paints are materials applied to different surfaces basically for decorative and protective purposes. Yet today the market for these materials is being subjected to increasingly tougher specifications. In addition ...

Order out of disorder in ice

The glass structure of a material is often believed to mimic its corresponding liquid. Polyamorphism between ices has been used as a guide to elucidate the properties of liquid water. But how many forms of amorphous ices ...
