Adding transparency to graphene paper improves supercapacitor capacitance
Inorganic nanowire follows the crystal structure of its graphene template
Chemical vapor deposition enables production of pure, uniform coatings of metals or polymers
In a sense, says MIT chemical engineering professor Karen Gleason, you can trace the technology of chemical vapor deposition, or CVD, all the way back to prehistory: "When the cavemen lit a lamp and soot ...
Winding borders may enhance graphene
Far from being a defect, a winding thread of odd rings at the border of two sheets of graphene has qualities that may prove valuable to manufacturers, according to Rice University scientists.
'Diamane': Diamond film possible without the pressure
(Phys.org) —Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems.
Argonne scientists are first to grow graphene on silver
(Phys.org) —Silver, meet graphene. Super strong, super light, near totally transparent and one of the best conductors of electricity ever discovered, graphene is a one-atom-thick sheet of carbon atoms that ...
Hybrid nanowires eyed for computers, flexible displays
A new process for coating copper nanowires with graphene - an ultrathin layer of carbon – lowers resistance and heating, suggesting potential applications in computer chips and flexible displays.
Symmetry matters in graphene growth
What lies beneath growing islands of graphene is important to its properties, according to a new study led by Rice University.
A new way to make sheets of graphene
Graphene's promise as a material for new kinds of electronic devices, among other uses, has led researchers around the world to study the material in search of new applications. But one of the biggest limitations ...
Hybrid nanotube-graphene material promises to simplify manufacturing
(Phys.org) —Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University.
'White graphene' halts rust in high temps
(Phys.org) —Atomically thin sheets of hexagonal boron nitride (h-BN) have the handy benefit of protecting what's underneath from oxidizing even at very high temperatures, Rice University researchers have ...
Even with defects, graphene is strongest material in the world
In a new study, published in Science May 31, 2013, Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its ...
