Scientists waste no time in growing graphene

Researchers have managed to grow graphene - commonly used in pencils but now terribly expensive - food, insects and waste

, garbage and errors in Texas, give hope that Britain will develop a lucrative business empire techology new base soon, and not just at the end. This is to obtain usable quantities of graphene - a carbon dimensions. American experience, it seems ridiculous that drew attention to something, showing a cheap way to get what is now the substance terribly expensive.

Scientists have long known that graphene is, and what is common. The gray matter consists pencils countless layers of graphene, adhering to each other. When scribble a mass newsletters layers, subsequently holding the sheet of paper. A few years ago, Andre Geim and Kostya Novoselov, University of Manchester, using intelligence, a pen and some tape to separate individual graphene layers. Obtained small amounts -. But it was surprisingly more than any other rose

To do this, and then using their graphene to discover a variety of physical properties and potential industrial uses, Geim and Novoselov were awarded the Nobel Prize in 2010 and knighted in 2011.

next year - this year - the British government announced it would spend £ 38 million to establish a Geim / National Institute Novoselov graphene centered at the University of Manchester in order to "put this research into commercial success. "

But there is a big problem. Even small amounts of graphene still cost much more than the industry can offer dream.

• Last year, only three years after scientists Mexican tequila is in diamonds - they are just an expensive form of carbon - chemical quietly Texas fucked with biscuits, cockroaches and products bad biowaste. Texans produces graphene, a form of carbon more expensive - much more expensive -. That diamonds

Tequila diamonds Physics, National Autonomous University of Mexico, published his story in the document entitled Growth diamond films Tequila. Co-author Javier Morales said he did later with tequila diamonds cheaper on the market, to demonstrate the power of his art.

This same spirit is manifest in the experience of Texas, led by Jim Tour, Ruan Gedeng, Sun Zhiwei Peng Zhengzong and Rice University in Houston, and documented in a study on growth of graphene food , insects and debris.

Others, however, had developed ways to grow graphene. These other methods expensive start-containing carbon highly purified chemical feedstocks. Tour of Rice and colleagues write that "carbon sources and much less expensive, such as food, insects and waste, can be used without purification for the monolayer graphene increasingly high quality."

explain how to produce graphene from (at different times): Girl Scout cookies, chocolate, grass, a plastic plate, a cockroach leg, and feces of a dachshund. Their tools. Copper foil, the argon gas and a tube furnace 1050-degrees Centigrade ()
by his own estimation, a box of Girl Scout cookies could, in theory, at current prices, it is about $ 15 billion in graphene.
