The graphene research team, led by Professor Kian Ping Loh at the National University of Singapore, invented an ultra-slim broadband polarizer that uses graphene, a single-atomic-layer crystallized carbon, to convert light beam into polarized light.

The heart of a scanning probe microscope is a moveable, suspended tip, which, like the needle on a record player, reacts to small height variations on the surface, and turns these into signals that can be displayed on a computer. Researchers have now been able to create this tip, not out of solid material, as in the case of the record player, but out of an ultra-cold, dilute gas of atoms. To do this, they cooled an especially pure gas of rubidium atoms to a temperature less than a millionth of a degree above absolute zero temperature, and stored the atoms in a magnetic trap. This 'quantum tip' can be precisely positioned and enables the probing of nanostructured surfaces.

A radically new approach to the design of batteries, developed by researchers at MIT, could provide a lightweight and inexpensive alternative to existing batteries for electric vehicles and the power grid. The technology could even make 'refueling' such batteries as quick and easy as pumping gas into a conventional car.
