Rice University Rice University researchers see nanodiamonds created in coal fade away in seconds Images taken by Rice University scientists show that some diamonds are not forever. The Rice researchers behind a new study that explains the creation of nanodiamonds in treated coal also show that some microscopic diamonds only last seconds before fading back into less-structured forms of carbon under the impact of an electron beam. The research by Rice chemist Ed Billups and his...

SANTA CLARA, Calif., May 14, 2014 /PRNewswire/ -- Element Six, the world leader in synthetic diamond supermaterials and a member of the De Beers Group of Companies, today announced that its Gallium Nitride (GaN)-on-Diamond wafers have been proven by Raytheon Company to significantly outperform industry standard Gallium Nitride-on-Silicon Carbide (GaN-on-SiC) in RF devices--reducing thermal resistance, increasing RF power density, and preserving RF functionality....

Physicists Discover How To Change The Crystal Structure Of Graphene
2014-05-01 03:38:14

Daniel Stolte, University of Arizona A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil lead, with an electric field, an important step toward the possible use of graphene in microprocessors that would be smaller and faster than current, silicon-based technology. Graphene consists of extremely thin sheets of graphite: when writing with a pencil, graphene sheets slough off the pencil's graphite...

Graphene Is Only As Strong As Its Weakest Link

Mike Williams, Rice University Rice, Georgia Tech experiments determine real-world limits of two-dimensional carbon There is no disputing graphene is strong. But new research by Rice University and the Georgia Institute of Technology should prompt manufacturers to look a little deeper as they consider the miracle material for applications. The atom-thick sheet of carbon discovered this century is touted not just for its electrical properties but also for its physical strength and...

How Can Graphene Sheets Be Utilized In Real-world Devices?
2014-04-25 03:15:43

National Science Foundation Fundamental research in phonon scattering helps researchers design graphene materials for applications Graphene, a one-atom-thick form of the carbon material graphite, has been hailed as a wonder material--strong, light, nearly transparent and an excellent conductor of electricity and heat--and it very well may be. But a number of practical challenges must be overcome before it can emerge as a replacement for silicon and other materials in microprocessors and...

Kitchen Science: Making Graphene In A Blender
2014-04-23 12:24:52

Brett Smith for redOrbit.com - Your Universe Online Graphene is a form of electrically conductive carbon being hailed as a miracle material capable of revolutionizing everything from high-end electronics to biological engineering. A new study from a large team of British and Irish researchers has described a recipe for graphene that only requires a few common household materials and a kitchen blender. The study, which was published in the journal Nature Materials, basically tacked on...

Corundum is the crystalline form of aluminium oxide and one of the rock-forming minerals. Corundum is naturally clear, but can have different colors when impurities are added. Transparent specimens are used as gems, called ruby if red, while all other colors are called sapphire. The word corundum comes from the Hindi kurand. The oxygen atoms in corundum are arranged in a hexagonal close-packing, with the smaller aluminium atoms occupying 2/3 of the octahedral gaps. The coordination of the...
