With 'ribbons' of graphene, width matters
Using graphene ribbons of unimaginably small widths – just several atoms across – a group of researchers at the University of Wisconsin-Milwaukee (UWM) has found a novel way to "tune" the wonder material, ...
Measuring the mass of 'massless' electrons
(Phys.org)—Individual electrons in graphene are massless, but when they move together, it's a different story. Graphene, a one-atom-thick carbon sheet, has taken the world of physics by storm—in part, ...
A nanosensor to identify vapors based on a graphene-silicon heterojunction Schottky diode
Among other carbon-based nanomaterials, graphene represents a great promise for gas sensing applications. In 2009 the detection of individual gas molecules of NO[sub]2[/sub] adsorbed onto graphene surface ...
Making graphene in your kitchen
Graphene has been touted as a wonder material—the world's thinnest substance, but super-strong. Now scientists say it is so easy to make you could produce some in your kitchen.
A review article summarizes the state-of-the-art knowledge about graphene grain boundaries
Graphene has attracted significant interest both for exploring fundamental science and for a wide range of technological applications. Chemical vapor deposition (CVD) is currently the only working approach ...
Thermal vision: Graphene light detector first to span infrared spectrum
The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens.
Graphene's love affair with water
Graphene has proven itself as a wonder material with a vast range of unique properties. Among the least-known marvels of graphene is its strange love affair with water.
Team finds electricity can be generated by dragging saltwater over graphene
Physicists discover how to change the crystal structure of graphene
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 ...
'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.
Graphene balloon yields unprecedented images of hydrated protein molecules
(Phys.org) —A graphene water balloon may soon open up new vistas for scientists seeking to understand health and disease at the most fundamental level.
Another tiny miracle: Graphene oxide soaks up radioactive waste
(Phys.org)—Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at Rice University and Lomonosov Moscow State University have found.
New form of quantum matter: Natural 3D counterpart to graphene discovered
The discovery of what is essentially a 3D version of graphene – the 2D sheets of carbon through which electrons race at many times the speed at which they move through silicon - promises exciting new things ...
Researchers model world's first carbon-based 'spaser'
(Phys.org) —A new version of "spaser" technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing.
