Graphene: from a conceptual material to a material of the future
Costas Galiotis FORTH/ ICE-HT and Dept. Materials Science, University of Patras Graphene is a perfect 2D crystal of covalently bonded carbon atoms and forms the basis of all graphitic structures[1,2]. The material was well known as a concept structure (platform) to mathematicians and modellers for many years and to the material physicists and scientists as […]
Move over graphene, silicene is the new star material
April 30, 2012
AFTER only a few years basking in the limelight, wonder material graphene has a competitor in the shape of silicene. For the first time, silicon has been turned into a sheet just one atom thick. Silicene is thought to have similar electronic properties to graphene but ought to be more compatible with silicon-based electronic devices. […]
Graphene Battery Turns Ambient Heat Into Electric Current
March 5, 2012
Physicists have built a graphene battery that harvests energy from the thermal movement of ions in solution Here’s an interesting idea for a battery. The thermal velocity of ions in aqueous solution is huge–hundreds of metres per second at room temperature. And yet few people have studied this process or its potential to generate current. […]
Could graphene be the new silicon?
November 13, 2011
It started with a few experiments with Scotch tape and a pencil. Then graphene, stronger than steel, one atom thick and a super-conductor, was born, a wonder material that could be as revolutionary as silicon, say its Nobel prize-winning creators. Now with £50m from the UK government, they’re out to prove it. Somehow it seems […]
Supercapacitor electrodes go for a dip
October 22, 2011
A new and simple “dipping” technique that can significantly improve the performance of supercapacitors has been developed by researchers at Stanford University in the US. The method, dubbed “conductive wrapping”, could be applied to a range of electrode materials. It might even be used to improve next-generation electrodes made from sulphur, lithium manganese phosphate and […]

Graphene in Space
August 16, 2011
Honeycomb Carbon Crystals Possibly Detected in Space NASA’s Spitzer Space Telescope has spotted the signature of flat carbon flakes, called graphene, in space. If confirmed, this would be the first-ever cosmic detection of the material — which is arranged like chicken wire in flat sheets that are one atom thick. Graphene was first synthesized in […]
Graphene gives up more of its secrets
July 16, 2011
Graphene, a sheet of carbon only a single atom thick, was an object of theoretical speculation long before it was actually made. Theory predicts extraordinary properties for graphene, but testing the predictions against experimental results is often challenging. Now researchers using the Advanced Light Source (ALS) at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley […]

Graphene integrated circuit is a first
June 10, 2011
IBM researchers have made the first graphene circuit in which all of the circuit elements are integrated on a compact single chip. The new circuit is another important step forward for graphene-based electronics and potential applications include wireless communications and amplifiers…..

Graphene may reveal the grain of space-time
May 13, 2011
COULD the structure of space and time be sketched out inside a cousin of plain old pencil lead? The atomic grid of graphene may mimic a lattice underlying reality, two physicists have claimed, an idea that could explain the curious spin of the electron. Graphene is an atom-thick layer of carbon in a hexagonal formation. […]
How To Make Graphene Paper
May 5, 2011
A new model predicts the properties of paper made from graphene sheets Carbon fibres were developed in the 1950s and have since helped to revolutionise the design, manufacture and performance of everything from yachts and planes to cars and bicycles. Now, 60 years later, a new material looks set to have a similar impact: graphene […]
