Latest Andre Geim Stories
Alan McStravick for redOrbit.com - Your Universe Online In 2004, the pure carbon material known as graphene was isolated by two University of Manchester Nobel Laureates, Andre Geim and Professor Kostya Novoselov, quickly leading to the discovery of a whole new family of one-atom-thick materials. Now researchers from the University of Manchester and National University of Singapore have shown that by building multi-layered heterostructures of graphene in a three-dimensional stack,...
redOrbit Staff & Wire Reports - Your Universe Online A steep rise in the number of patents involving graphene, one of the thinnest, lightest, strongest and most conductive materials in the world, reveals a global race to harness the potential of this novel material. Graphene, which was identified only as recently as 2004, is harder than diamond, a single molecule thick, as flexible as rubber and much more conductive than copper, giving it tremendous potential for applications in...
Brett Smith for redOrbit.com - Your Universe Online Government investments into certain private companies, sometimes derided as “picking winners and losers,” can be controversial, yet the U.K. government has stepped into the breach this week and announced that it will be investing over $35 million in an effort to commercialize graphene, a new ‘super-material’. Invented by two scientists at the University of Manchester, Konstantin Novoselov and Andre Geim, graphene is an...
NASA Tiny sensors -- made of a potentially trailblazing material just one atom thick and heralded as the “next best thing” since the invention of silicon -- are now being developed to detect trace elements in Earth’s upper atmosphere and structural flaws in spacecraft. Technologist Mahmooda Sultana, who joined NASA’s Goddard Space Flight Center in Greenbelt, Md., two years ago and has since emerged as Goddard’s go-to expert in the development of graphene-based technology, has...
April Flowers for redOrbit.com – Your University Online Graphene is the world's thinnest, strongest, and most conductive material. It is made of pure carbon, and only one atom thick. Nobel prizewinner Professor Kostya Novoselov and an international team have created a "Graphene Roadmap" to show what the material could truly achieve. Graphene was first isolated in 2004 at the University of Manchester by Professor Novoselov and Professor Andre Geim. The paper, published in Nature,...
Engineering faculty and students at the University of Colorado Boulder have produced the first experimental results showing that atomically thin graphene membranes with tiny pores can effectively and efficiently separate gas molecules through size-selective sieving. The findings are a significant step toward the realization of more energy-efficient membranes for natural gas production and for reducing carbon dioxide emissions from power plant exhaust pipes. Mechanical engineering...
Sandwiching individual graphene sheets between insulating layers in order to produce electrical devices with unique new properties, the method could open up a new dimension of physics research. Writing in Nature Materials, the scientists show that a new side-view imaging technique can be used to visualize the individual atomic layers of graphene within the devices they have built. They found that the structures were almost perfect even when more than 10 different layers were used to build...
LONDON, July 11, 2012 /PRNewswire/ -- You may not have heard of graphene but it has been described as the "miracle material" of the 21st Century [http://www.247bull.com/graphene-from-nobel-prize-to-investment-opportunity ]. Indeed, graphene has the potential to transform almost every aspect of our lives, and that's why 247Bull.com [http://www.247bull.com ] wants to bring it to the attention of every investor. Graphene was discovered in 2004 by Dr Kostya Novoselov and...
Findings could have applications in high-speed communications fields. Graphene has caused a lot of excitement among scientists since the extremely strong and thin carbon material was discovered in 2004. Just one atom thick, the honeycomb-shaped material has several remarkable properties combining mechanical toughness with superior electrical and thermal conductivity. Now a group of scientists at Iowa State University and the Department of Energy's Ames Laboratory, led by physicist...
In a paper published this week in Science, a Manchester team lead by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research. Their research shows a transistor that may prove the missing link for graphene to become the next silicon. Graphene – one atomic plane of carbon – is a remarkable material with endless unique properties, from electronic to chemical and from optical to mechanical. One of many potential...
