Organic chemistry: Leading light waves astray

The development of structured synthetic materials with unusual electromagnetic properties, so-called metamaterials, promises to provide access to special physical effects of great technological interest. Metamaterials have ...

Sensitive bomb detector to rove in search of danger

European researchers have developed and tested a light-weight device capable of detecting extremely minute quantities of explosives from up to 20 metres away, providing an invaluable law-enforcement tool in the fight against ...

Spheres can form squares

Everybody who has tried to stack oranges in a box knows that a regular packing of spheres in a flat layer naturally leads to a hexagonal pattern, where each sphere is surrounded by six neighbours in a honeycomb-like fashion. ...

Scientists discovering new uses for tiny carbon nanotubes

Nanotubes are stronger than steel and smaller than any element of silicon-based electronics. They can potentially process information faster while using less energy. The challenge has been figuring out how to incorporate ...

Liquid lens shrinks laser measuring device

Lasers are widely used in many areas of science, industry and medicine and the quality of the beams they produce needs to be measured to make sure they perform correctly. As electronic devices become smaller and smaller over ...

New magnetic graphene may revolutionise electronics

Researchers from IMDEA-Nanociencia Institute and from Autonoma and Complutense Universities of Madrid (Spain) have managed to give graphene magnetic properties. The breakthrough, published in the journal Nature Physics, opens ...
