Dry Ice Makes Graphene Cheaper, Greener |

Micro-processor manufacturers are buzzing out loud on the miraculous wonders of the graphene-based transistors, whereby this particular material is touted to be tougher, and can be outfitted with tremendous amount of transistors, which can be translated into higher clock speeds for micro-processors. However, since graphene is still relatively new, producing graphene-based microprocessors is still expensive, as preliminary fabrication methods are costly and time consuming – up until now.
Apparently, researchers at the Northern Illinois University have discovered a method that can be used to make graphene at a much cheaper, greener, and faster rate. Basically, the researchers used dry ice in their manufacturing process, whereby burning magnesium in frozen carbon dioxide produces a thin layer of the carbon nanostructure, ie graphene. The method can be used to produce graphene at a larger scale, and it is also relatively cheaper, faster, and more environmentally friendly, when compared to conventional methods that use boatloads of chemicals.
