Forget diamonds, graphene is now the world's hardest material. And all sorts of developers most likely want to get their hands on it.

Nokia looks to be ahead of the game in this graphene race. The Finnish mobile-phone maker announced today that it was one of the recipients of a $1.35 billion grant from the European Union to do research and development on the supermaterial over the next 10 years.

"Nokia is proud to be involved with this project, and we have deep roots in the field -- we first started working with graphene already in 2006,&… Read more

Year in, year out, Intel executive Mike Mayberry hears the same doomsday prediction: Moore's Law is going to run out of steam. Sometimes he even hears it from his own co-workers.

But Moore's Law, named after Intel co-founder Gordon Moore, who 47 years ago predicted a steady, two-year cadence of chip improvements, keeps defying the pessimists because a brigade of materials scientists like Mayberry continue to find ways of stretching today's silicon transistor technology even as they dig into alternatives. (Such as, for instance, super-thin sheets of carbon graphene.)

Oh, and don't forget the money that'… Read more

Some tech just sounds too good to be true. A removable, wireless sensor that adheres to dental enamel and can detect trace amounts of harmful bacteria just might fall into the too-much-information category for the squeamish among us.

But the silk, gold, and graphene-based sensor that looks a bit like a temporary tattoo could play a key role in detecting and treating various diseases and conditions, the developers at Princeton University say.

"This is a real-time, wireless response from a sensor that can be directly interfaced with a variety of biomaterials," principal investigator Michael McAlpine, an assistant professor … Read more

Swiss scientists say they have a new candidate for making flexible electronic devices, after they successfully manufactured the first molybdenite microchip.

The integrated circuit was made at the Laboratory of Nanoscale Electronics and Structures (Lanes), of the Ecole Polytechnique Federale de Lausanne. Yesterday, the researchers said it showed how molybdenite microchips could be made smaller than silicon chips, use less electricity than silicon, and be more flexible than silicon, the mainstay of today's computers.

The flexibility of molybdenite could also make it suitable for creating rollable computers or devices that can be attached to a person's skin, the … Read more

Rice University researchers are bending graphene to meet their needs with a technique that promises progress on the road to nano-scale electronic circuits.

In a paper published yesterday in Nature Communications, researchers describe a way to alter graphene into "hybrid superlattices," a material potentially suitable for electronics and optical devices.

Graphene, which is a one-atom thick layer of carbon atoms interconnected in a honeycomb structure, is touted as a wonder material for a variety of uses, including faster and smaller electronics. As a material, it has excellent electrical conductivity but because it is a semimetal, researchers are still … Read more

A mesh of one-atom-thick graphene foam could become man's best friend in sniffing out explosives.

The Rensselaer Polytechnic Institute announced last week the creation of a graphene material that is 10 times more sensitive when detecting gases than current sensors used by bomb squads. It's also robust and can be made cheaply, according to its inventors.

Using the material to sense ammonia and nitrogen dioxide gases given off by explosive devices could lead to more sensitive and long-lasting tools for bomb detection. It can also be modified for industrial and medical uses in which sensors detect leaks of … Read more
