Rice University, Russian researchers lay out rules for ultrathin ‘diamane’ Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems. Scientists have speculated about it and a few labs have even seen signs of what they call diamane, an extremely thin film of diamond that has all of diamond’s superior semiconducting and thermal properties. Now researchers at Rice University and in Russia have calculated a “phase...

Rice University theory predicts formation of conductive sub-nano ℠wires´ in two-dimensional materials A new material structure predicted at Rice University offers the tantalizing possibility of a signal path smaller than the nanowires for advanced electronics now under development at Rice and elsewhere. Theoretical physicist Boris Yakobson and postdoctoral fellow Xiaolong Zou were investigating the atomic-scale properties of two-dimensional materials when they found to their...

Rice University lab's nanoreactor theory could advance quality of material's growth Like tiny ships finding port in a storm, carbon atoms dock with the greater island of graphene in a predictable manner. But until recent research by scientists at Rice University, nobody had the tools to make that kind of prediction. Electric current shoots straight across a sheet of defect-free graphene with almost no resistance, a feature that makes the material highly attractive to engineers who would...

Air Force Research Laboratory experiment shows chirality of tube controls speed of growth The Air Force Research Laboratory in Dayton, Ohio, has experimentally confirmed a theory by Rice University Professor Boris Yakobson that foretold a pair of interesting properties about nanotube growth: That the chirality of a nanotube controls the speed of its growth, and that armchair nanotubes should grow the fastest. The work is a sure step toward defining all the mysteries inherent in what...

[ Watch the Video ] Rice University simulations show carbon sheets tear along energetically favorable lines Research from Rice University and the University of California at Berkeley may give science and industry a new way to manipulate graphene, the wonder material expected to play a role in advanced electronic, mechanical and thermal applications. When graphene — a one-atom thick sheet of carbon — rips under stress, it does so in a unique way that puzzled...

Materials scientists find new way to control electronic properties of graphene 'alloys' Rice University materials scientists have made a fundamental discovery that could make it easier for engineers to build electronic circuits out of the much-touted nanomaterial graphene. Graphene's stock shot sky-high last year when the nanomaterial attracted the Nobel Prize in physics. Graphene is a layer of carbon atoms that is just one atom thick. When stacked atop one another, graphene sheets form...

In calculating energies for graphene, Rice researchers find clues to chiral control New research at Rice University could ultimately show scientists the way to make batches of nanotubes of a single type. A paper in the online journal Physical Review Letters unveils an elegant formula by Rice University physicist Boris Yakobson and his colleagues that defines the energy of a piece of graphene cut at any angle. Yakobson, a professor in mechanical engineering and materials science and of...

Rice researchers find metallacarboranes may meet DOE storage goals New research by Rice University scientists suggests that a class of material known as metallacarborane could store hydrogen at or better than benchmarks set by the United States Department of Energy (DOE) Hydrogen Program for 2015. The work could receive wide attention as hydrogen comes into play as a fuel of the future for cars, in fuel cells and by industry. The new study by Rice theoretical physicist Boris Yakobson and his...

Rice physicists dig theoretical wells to mine quantum dots Graphane is the material of choice for physicists on the cutting edge of materials science, and Rice University researchers are right there with the pack "“ and perhaps a little ahead. Researchers mentored by Boris Yakobson, a Rice professor of mechanical engineering and materials science and of chemistry, have discovered the strategic extraction of hydrogen atoms from a two-dimensional sheet of graphane naturally opens up...

New video showing the atom-by-atom growth of carbon nanotubes reveals they rotate as they grow, much like the halting motion of a mechanical clock's second hand. FEM video from Universit© Lyon1/CNRS shows the rotation of the nanotube during growth. The observation helps confirm a new rotational theory of carbon nanotube growth offered by Rice researchers in February.Published online this month by researchers at France's Universit© Lyon1/CNRS and Houston's Rice University, the...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
