Quasiparticles

Ohio State researchers have shown how a common ceramic material can change its thermal conductivity in response to an electrical field, opening the door to solid-state heat switches that could make thermoelectric generators much more efficient.

Exciting times are ahead in the high-tech industries with the discovery by three independent groups that a new class of materials mimic the special electronic properties of graphene in 3D.

Research teams at Cal Tech and UC-Berkeley have invented a nanofocusing device that shrinks light beams down to a few nanometers in size.
