- Single Electron Squats in Graphite Vacancy
- A one-atom-thick sheet of carbon known as graphene could show a new and useful type of magnetism. It could be generated by electrons hosted at sites where a carbon atom is missing. In the 5 March Physical Review Letters, Spanish researchers have shown with a scanning tunneling microscope that a lone electron exists at such a site, at least in graphite, which is similar to graphene.

- Silicon whiskers catch rays well
- Roll out the micro-carpet--a new solar-cell design based on a blanket of silicon rods could produce electricity at a fraction of the cost of conventional solar devices.

- First light for Germanium laser
- The first infrared-emitting germanium laser has been created by researchers in the US. The development could be an important step towards creating optical components such as lasers from silicon--which like germanium is an indirect-gap semiconductor--rather than direct-gap materials such as indium phosphide.
