In a development that could lead to novel carbon composites and touch-screen displays, researchers from Rice University and the Technion-Israel Institute of Technology recently unveiled a new method for producing bulk quantities of one-atom-thick sheets of carbon called graphene.
The research is available online in the journal Nature Nanotechnology.
When stacked together, graphene sheets make graphite, which has been commonly used as pencil lead for hundreds of years. It wasn't until 2004 that stand-alone sheets of graphene were first characterized with modern nanotechnological instruments. Since then, graphene has come under intense scrutiny from materials scientists, in part because it is both ultrastrong and highly conductive.
