Rice University lab finds table sugar, metallic sheets produce pristine graphene in one step

17-11-2010

Future computers may run a little sweeter, thanks to a refinement in the manufacture of graphene at Rice University. Rice researchers have learned to make pristine sheets of graphene, the one-atom-thick form of carbon, from plain table sugar and other carbon-based substances. They do so in a ...

Rice researchers' method untangles long tubes, clears hurdle toward armchair quantum wire

19-07-2010

Rice University scientists have found the "ultimate" solvent for all kinds of carbon nanotubes (CNTs), a breakthrough that brings the creation of a highly conductive quantum nanowire ever closer. Nanotubes have the frustrating habit of bundling, making them less useful than when they're ...
