Grafeno

Se viene el grafeno...

Graphene is a form of carbon, one-atom thick in structure, with an octagonal, or honeycomb, appearance. Independent testing has shown it to be one of the strongest materials known with a breaking strength 200 times greater than steel. It has been described as the ‘thinnest and lightest material there is,’ and could pave the way for a whole new generation of smaller, better, faster electronics.

IBM is rapidly producing faster and faster graphene transistors, recently demonstrating a 155GHz model. It outperformed IBM’s previous record which produced a cut-off frequency of 100GHz. The company has also made integrated circuits from graphene smaller than a grain of salt.

The Internet could benefit immensely from graphene by having connection speeds ten-times faster than at present, thanks to researchers at UC Berkeley, who created tiny, one-atom-thick modulators that can switch the data-carrying light on and off in a fiber-optic connection much faster than current technology.

At Vanderbilt University, Tennessee, graphene has been made into super hydrophobic and hydrophilic sheets. These sheets manipulate water droplets and can be used to manufacture windshields that don’t require wipers, clothes that cause stains to simply bounce off, and lenses that never fog.
