Non-stick graphene makes anti-glare breakthrough

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.

Graphene on the brain, thanks to $500k grant

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.

Material found in pencils may hold key to faster computer chips

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.

Looking at single atoms of hydrogen

As you probably know, graphene is a one-atom-thick sheet of carbon atoms packed in a dense two-dimensional honeycomb lattice. And it recently became very popular recently as a basis for ultra-fast transistors. Now, according to Science News, U.S. researchers are using graphene to image individual hydrogen atoms via a standard transmission electron microscope (TEM) technology. Until now, heavy atoms, such as carbon, could be detected by electron microscopy. But the physicists from Berkeley, California, have shown it's possible to track the smallest atoms, hydrogen ones. But read more...

Carbon copy the future of physics

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.
