Better cathode materials for lithium-sulphur-batteries

Researchers have for the first time fabricated a nanomaterial made from nanoparticles of a titanium oxide compound that is characterized by an extremely large surface area, and tested it as a cathode material in lithium-sulphur batteries. The highly porous nanomaterial possesses high storage capacity that remains nearly constant over many charging cycles.

Ultrafast tunable semiconductor metamaterial created

An international team of researchers have devised an ultrafast tunable metamaterial based on gallium arsenide nanoparticles. The new optical metamaterial paves the way to ultrafast information transfer on the nanoscale.
