Scientists have leaped over a major hurdle in efforts to begin commercial production of a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell phones.
Called graphene, the material consists of a layer of graphite 50,000 times thinner than a human hair with unique electronic properties. Their study appears in ACS' Nano Letters, a monthly journal.
Victor Aristov and colleagues indicate that graphene has the potential to replace silicon in high-speed computer processors and other devices.
Standing in the way, however, are today's cumbersome, expensive production methods, which result in poor-quality graphene and are not practical for industrial scale applications.
Aristov and colleagues report that they have developed "a very simple procedure for making graphene on the cheap." They describe growing high-quality graphene on the surface of commercially available silicon carbide wafers to produce material with excellent electronic properties.
It "represents a huge step toward technological application of this material as the synthesis is compatible with industrial mass production," their report notes.

Water Oxidation Advance Boosts Potential For Solar Fuel
Atlanta GA (SPX) Mar 15, 2010
Emory University chemists have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using only water and sunlight. The breakthrough, published in the journal Science, was made in collaboration with the Paris Institute of Molecular Chemistry. The fastest, carbon-free molecular water oxidation catalyst (WO ... read more
