1000 km range thanks to a new battery concept

You cannot get far today with electric cars. One reason is that the batteries require a lot of space. Fraunhofer scientists are stacking large cells on top of one another. This provides vehicles with more power. Initial tests ...

Sustainable ceramics without a kiln

The manufacture of cement, bricks, bathroom tiles and porcelain crockery normally requires a great deal of heat: a kiln is used to fire the ceramic materials at temperatures well in excess of 1,000°C. Now, material scientists ...

How bioceramics could help fight gum disease

Severe gum disease known as periodontitis can lead to tooth loss, and treating it remains a challenge. But new approaches involving silicon nitride, a ceramic material used in spinal implants, could be on the way. The surface ...

Computing a textbook of crystal physics

Disturbing a material's crystal lattice can create a charge imbalance that leads to a voltage across the material. This phenomena, called the "piezoelectric effect," was first demonstrated in 1880 by Jacques and Pierre Curie ...
