‘Graphene Roadmap’ Paves The Way
2012-10-11 08:05:36

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...

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...

According to a new study, membranes based on the material graphene can be used to distill alcohol. The researchers wrote in the journal Science that they created the membrane from graphene oxide, which is a chemical derivative of graphene. Graphene is the thinnest known material in the universe and the strongest ever measured.  it conducts electricity and heat better the any other material as well. A University of Manchester academics won the Noble Prize in Physics in 2010 by...

The physical property of magnetism has historically been associated with metals such as iron, nickel and cobalt; however, graphite — an organic mineral made up of stacks of individual carbon sheets — has baffled researchers in recent years by showing weak signs of magnetism. The hunt for an explanation has not been without controversy, with several research groups proposing different theories. The most recent suggestion, published today, 27 January, in the journal EPL...

Graphene is one of the wonders of the science world, with the potential to create foldaway mobile phones, wallpaper-thin lighting panels and the next generation of aircraft. The new finding at the University of Manchester gives graphene's potential a most surprising dimension — graphene can also be used for distilling alcohol. In a report published in Science, a team led by Professor Sir Andre Geim shows that graphene-based membranes are impermeable to all gases and liquids...
