System Bits: Aug. 19

Revealing the purity of graphene Graphene may be tough, but those who handle it had better be tender, according to researchers from Rice University and Osaka University who have come up with a simple way to spot contaminants given that the environment surrounding the atom-thick carbon material can influence its electronic performance. It is so easy to accidentally introduce impurities into ... » read more

Power/Performance Bits: March 4

Photon glue Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials and this effect could harness the most useful characteristics from each material for hybrid solar cells and high efficiency lighting, among other applications. To this end, researchers at the University of Michigan and Queens Coll... » read more
