A collaborative project between Singapore and UK researchers has revealed another useful property of graphene; it can offer protection from laser pulses.Scientists at the National University of Singapore, DSO Laboratories and the University of Cambridge were investigating ways of blocking graphene’s natural tendency to stack and form the more familiar graphite – that’s pencil lead to you and me.
A Swedish team of researchers has linked two chips using carbon nanotubes, which they say promise to be more reliable than copper interconnects for commercial production of 3D chip stacks
Whether you make the stuff out of girls scout cookies or flake it off a chunk of graphite, miracle material graphene could soon be coming to an neural implant near you.Researchers in the US have been given almost half a million dollars to work graphene – which they think will be more stable than traditional materials – into implantable electrode systems.
We talk a lot about graphene, on this blog. The wonderful two dimensional lattice of carbon with its hexagonal, chickenwire structure.
Graphene gets its unique properties from the geometry of its carbon atoms. But how does something so simple produce such profoundly different physics?
When first discovered, graphene was odd. Now odd is too small a word for a material seemingly set on winning all the records a material can win
Sellotape and sugar rub shoulders with high-temperature furnaces and low-pressure chambers in a rush to produce graphene, which aims to be the 21st century's successor to silicon
Carbon is valuable as diamond and in oil, but a new form of the pure element may be even more important in our future. ZDNet UK presents the first in a series of features on graphene
Samsung, LG and others have been fined €648m by the European Commission for their involvement in a price-fixing cartel that fixed minimum prices and price ranges of LCD displays
From the Nobel prize-winning team who brought you the honeycomb structure sheet of carbon atoms that is graphene, comes the sequel: Fluoro-graphene: 2D Teflon.Kostya Novoselov and Andre Geim led an international team of scientists modify a sheet of graphene so that it became an insulator.
Wonder material graphene gets more wonderfully mysterious the closer scientists look. And the latest attempt to understand how the atom-thick sheet of carbon atoms carries current the way it does has left physicists with more questions than they started with.
University of California, Berkeley researchers discovered that graphene can be structurally manipulated in such a way, the electrons behave as they would in a magnetic field.
New research shows promise for super-thin films with thermal superpowers. If electronics enter into a Graphene Age, could overheating become a relic of the past?
IBM Research plans to announce that it has demoed a radio-frequency graphene transistor with the highest frequency so far
The production of graphene has just become a whole lot easier. Northwestern University scientists have demonstrated that graphite oxide can be converted instantly to graphene by exposing the material to a pulse of light from an ordinary camera flash.
Move over silicon because graphene, the sheet-like form of carbon found in graphite pencils, may hold the key to smaller and faster electronics. In a paper published in the journal Advanced Materials, engineers at Ohio State University describe a technique for stamping many graphene sheets onto a substrate at once, and in precise locations.
As you probably know, graphene is a one-atom-thick sheet of carbon atoms packed in a dense two-dimensional honeycomb lattice. And it recently became very popular recently as a basis for ultra-fast transistors. Now, according to Science News, U.S. researchers are using graphene to image individual hydrogen atoms via a standard transmission electron microscope (TEM) technology. Until now, heavy atoms, such as carbon, could be detected by electron microscopy. But the physicists from Berkeley, California, have shown it's possible to track the smallest atoms, hydrogen ones. But read more...
More exciting news from the increasingly carboniferous world of solid state physics. A paper from two researchers, Yakov Kopelevich in San Paulo and Pablo Esquinaz in Leipzig, reports that good old fashioned graphite has a whole bunch of exciting electronic properties and that this, rather than the currently fashionable single-atomic-sheet graphene, may well prove to be the most worthwhile substance to investigate for spintronics and other new ideas.
