A collaborative project between Singapore and UK researchers has revealed another useful property of graphene; it can offer protection from laser pulses.Scientists at the National University of Singapore, DSO Laboratories and the University of Cambridge were investigating ways of blocking graphene’s natural tendency to stack and form the more familiar graphite – that’s pencil lead to you and me.

Not content with taking on the might of silicon, now graphene in all its two-dimensional glory is giving the evil eye to copper. According to an announcement from Rensselaer Polytechnic Institute, graphene is a promising candidate to replace copper as the size of circuitry on chips shrinks ever smaller.
Whether you make the stuff out of girls scout cookies or flake it off a chunk of graphite, miracle material graphene could soon be coming to an neural implant near you.Researchers in the US have been given almost half a million dollars to work graphene – which they think will be more stable than traditional materials – into implantable electrode systems.
The production of graphene has just become a whole lot easier. Northwestern University scientists have demonstrated that graphite oxide can be converted instantly to graphene by exposing the material to a pulse of light from an ordinary camera flash.
Move over silicon because graphene, the sheet-like form of carbon found in graphite pencils, may hold the key to smaller and faster electronics. In a paper published in the journal Advanced Materials, engineers at Ohio State University describe a technique for stamping many graphene sheets onto a substrate at once, and in precise locations.
More exciting news from the increasingly carboniferous world of solid state physics. A paper from two researchers, Yakov Kopelevich in San Paulo and Pablo Esquinaz in Leipzig, reports that good old fashioned graphite has a whole bunch of exciting electronic properties and that this, rather than the currently fashionable single-atomic-sheet graphene, may well prove to be the most worthwhile substance to investigate for spintronics and other new ideas.
