Using DNA to assemble transistors from graphene Graphene is a sheet of carbon atoms arrayed in a honeycomb pattern, just a single atom thick. It could be a better semiconductor than silicon – if we could fashion it into ribbons 20 to 50 atoms wide. Could DNA help? Stanford chemical engineering professor Zhenan Bao, believes it could. Bao and her team of researchers hope to solve a problem... » read more

Rechargeable flow battery for cheaper, large-scale energy storage In a creation that may eventually enable cheaper, large-scale energy storage, MIT researchers have engineered a new rechargeable flow battery that doesn’t rely on expensive membranes to generate and store electricity. According to the researchers, the palm-sized prototype generates three times as much power per square centi... » read more

Grappling With Graphene
By Brian Fuller - 11 Mar, 2010 - Comments: 0

By Brian Fuller Silicon CMOS is a tough act to follow. The workhorse building block for the world’s electronics has been delivering for system designers for a half century. Despite hand-wringing over its apparent scalability limits, it shows only vague signs of slowing down. For nearly as many years, it seems, the next great material or alternative to silicon CMOS has popped into the indu... » read more
