Graphene finds work as rust-proof coating

While researchers hoping to make graphene a serious contender to silicon’s electronic throne have some work still ahead of them, the material is finding more immediate application in other industrial areas.(This is probably the materials science version of waiting tables while auditioning for film roles in your spare time.

Graphene coated DVD + LightScribe = Supercapacitor

Scientists at UCLA have put a Lightscribe DVD optical drive to work in their graphene research, and have used them to produce a graphene-based electrochemical supercapcitor that could make itself very useful in a world ever more dependent on battery power.In a paper published in the March 16 edition of the journal Science, the researchers explain that electrochemical capacitors have attracted a lot of interest because they can be charged and discharged much faster than traditional batteries.

Osborne puts £50m into UK graphene research

Chancellor George Osborne has promised £50 million for research into graphene, the carbon-based material tipped as a breakthrough in material science, nanotechnology and electronics.Graphene was discovered in 2004 by Dr (now Professor) Kostya Novoselov and Professor Andre Geim from the University of Manchester in work that won them the 2010 Nobel Prize for physics.

Transistors? Pah. IBM demos complete graphene circuit

IBM, having wowed us all in April with graphene transistors that run at 155GHz, has gone one step further and now reports success in building a high-speed, graphene-based circuit.The researchers, writing in the June 10 issue of Science, describe how they deposited multiple layers of graphene on a silicon wafer.

Scientists hear 'white graphene' bell toll for silicon circuits

Researchers at Rice University's Department of Mechanical Engineering and Materials Science have successfully created single-atom sheets of an insulator: hexagonal Boron Nitride (h-BN).The breakthrough could help graphene kick silicon back into the 20th century, paving the way for nanoscale field-effect transistors, quantum capacitors or biosensors.

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...
