Graphene, a one-atom-thick sheet of carbon with remarkable electrical properties, shows promise for future generations of high-speed transistors. It may have uses as diverse as the production of sensors or as scaffolding for tissue regeneration. But research is still in the early stages, in part because it’s so difficult to produce large quantities of graphene. Now two research groups are reporting ways to make graphene ribbons, ranging in width from a few nanometers to a few hundred nanometers. (source: spectrum.ieee.org)
