Plasma as a fast optical switch

Just like an electrical switch allows the flow of electricity into electrical circuits, relativistic transparency in plasma can act like a fast optical switch allowing the flow of light through otherwise opaque plasma.

Nanotechnology exhaust gas catalyst has 10x higher thermal agglomeration resistance than conventional materials

A research team at the International Center for Materials Nanoarchitectonics (MANA) in Japan has developed an exhaust gas catalyst material with approximately 10 times greater thermal agglomeration resistance than conventional materials. This dramatic improvement in thermal agglomeration resistance opens the road to a large reduction in the amount of rare metals used in exhaust gas purification technologies.

Low-cost, hybrid thermoelectrics

Scientists at the Berkeley Lab constructed a nanoscale composite thermoelectric material by wrapping a polymer that conducts electricity around a nanorod of tellurium - a metal coupled with cadmium in today's most cost-effective solar cells. This composite material is easily spin cast or printed into a film from a water-based solution.
