Graphene heat-transfer riddle unraveled
Chicago IL (SPX) Jun 22, 2015
Researchers have solved the long-standing conundrum of how the boundary between grains of graphene affects heat conductivity in thin films of the miracle substance - bringing developers a step closer to being able to engineer films at a scale useful for cooling microelectronic devices and hundreds of other nano-tech applications. The study, by researchers at the University of Illinois at Chicago, the University of Massachusetts-Amherst and Boise State University, is published online in Nano Letter ... read more
