The 2010 Nobel Prize in Physics went to the two scientists who first isolated graphene, one-atom-thick crystals of graphite. Now, a researcher with the University of Houston Cullen College of Engineering is trying to develop a method to mass-produce this revolutionary material. Graphene has several properties that make it different from literally everything else on Earth: it is the first two-dimensional material ever developed; the world's thinnest and strongest material; the best conductor...

Scientists have made a breakthrough toward creating nanocircuitry on graphene, widely regarded as the most promising candidate to replace silicon as the building block of transistors. They have devised a simple and quick one-step process based on thermochemical nanolithography (TCNL) for creating nanowires, tuning the electronic properties of reduced graphene oxide on the nanoscale and thereby allowing it to switch from being an insulating material to a conducting material. The technique...

Can graphene"”a newly discovered form of pure carbon that may one day replace the silicon in computers, televisions, mobile phones and other common electronic devices"”be made to bend, twist and roll? Physicists at UC San Diego and Boston University think so. In a paper published in the journal Physical Review B, the scientists say the propensity of graphene"”a single layer of carbon atoms arranged in a honeycomb lattice"” to stick to itself and form carbon...

Super-thin material advances toward next generation applications The single-atom thick material graphene maintains its high thermal conductivity when supported by a substrate, a critical step to advancing the material from a laboratory phenomenon to a useful component in a range of nano-electronic devices, researchers report in the April 9 issue of the journal Science. The team of engineers and theoretical physicists from the University of Texas at Austin, Boston College, and France's...

PTB has for the first time made graphene visible on gallium arsenide "“ A successful combination of two unique electronic materials It is the marriage of two top candidates for the electronics of the future, both eccentric and extremely interesting: Graphene, one of the partners, is an extremely thin fellow and besides, very young. Not until 2004 was it possible to specifically produce and investigate the single layer of carbon atoms. Its electronic properties are remarkable, because,...

Study is first to experimentally quantify thermal contraction of graphene Graphene is nature's thinnest elastic material and displays exceptional mechanical and electronic properties. Its one-atom thickness, planar geometry, high current-carrying capacity and thermal conductivity make it ideally suited for further miniaturizing electronics through ultra-small devices and components for semiconductor circuits and computers. But one of graphene's intrinsic features is ripples, similar to those...

Engineers at Ohio State University are developing a technique for mass producing computer chips made from the same material found in pencils. Experts believe that graphene -- the sheet-like form of carbon found in graphite pencils -- holds the key to smaller, faster electronics. It might also deliver quantum mechanical effects that could enable new kinds of electronics. Until now, most researchers could only create tiny graphene devices one at a time, and only on traditional silicon oxide...

U.S. scientists say they have developed a new process for mass producing the nanomaterial graphene in large quantities. Graphene -- essential in nanotechnology -- is created when graphite is reduced to a one-atom-thick sheet. It is among the strongest materials known and has an attractive array of benefits, the scientists said. UCLA researchers from the California NanoSystems Institute, led by Professors Yang Yang and Richard Kaner, have developed a method of placing graphite oxide paper...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
