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

Cookies

, 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.

Americans.

• 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.

DailyDirt: There's Nothing That Can't Be Deep Fried And Eaten

Know it is bad for our health, but somehow I can not get enough of the artery-clogging fried food because it tastes so good. If you are tired of dry roasted cooked Thanksgiving turkey, try to fry next time. Fry is not just a faster way to cook a turkey, but also produces a very tender and juicy bird with a super crispy skin. (However, all frying turkeys is dangerous if not done correctly - William Shatner, who almost burned his house trying to fry a turkey.) Fried turkey is not particularly unusual, but there is something pretty crazy ideas about deep fried foods. Here are some examples.

• In Austria, McDonald, recently offered a sandwich called McRibster, which was essentially a McRib had been breaded and fried. And as if that were not enough, also came with bacon and cheese (and some healthy things like lettuce and onion). [Url]
• fried butter balls first made its debut at the State Fair of Texas in 2009. However, the Iowa State Fair was taken to a new level last year with a staff of two ounces of butter, cinnamon dough dipped in honey, fried, then covered with a glaze of sugar. [Url]
Each year, the County Fair San Diego has some interesting fried foods. Here are some examples: fried chicken sandwiches Krispy Kreme, fried Twinkies, fried avocado fried brownies, fried Klondike bars, fried frog legs, deep fried crackers and scout fried Kool-Aid. [Url]

Facebook proposes more transparent privacy policy, wants to know what you think of it

Facebook had some weaknesses of privacy in a not too distant past, and has worked to improve its policies to better inform users how their Facebook information is used. Last year, the Office of the Data Protection Ireland made an audit using Facebook data and determined that, while Facebook does a good job, more information should be provided for each of us. Well, the social network has recently responded by creating a Hub and Conditions for countless policies so easy to find. Also adds new examples and explanations for the use of data about how the policy book "uses cookies on its site, while shedding some light on how our information is used for advertising and improving the operation of the site. There is also a detailed description of the activity log tool that allows you to see every bit of information we have been entrusted to Mr. Zuckerberg, so that you can better manage your photos and wall posts. These changes have not yet been set in stone, however, because Facebook wants to know what you think before you do. Just go to the Facebook site governance to examine changes and will provide information or resolve a concert Q & A session with the Chief Privacy Erin Egan on Monday (May 14) at noon , time to say face-to-face digital.
