Shrinky Dinks close the gap for nanowires
(Phys.org) —How do you put a puzzle together when the pieces are too tiny to pick up? Shrink the distance between them.
'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.
Researchers develop holography technology that could change the way we view the world
Since the 1960s, theatergoers have shelled out for crude 3-D glasses, polarized glasses, and shutter glasses to enhance their viewing experience. These basic devices, used to trick the brain into perceiving ...
Liberating devices from their power cords: New structural 'supercaps' take a lickin', keep on workin'
(Phys.org) —Imagine a future in which our electrical gadgets are no longer limited by plugs and external power sources. This intriguing prospect is one of the reasons for the current interest in building ...
Nanowires grown on graphene have surprising structure
(Phys.org) —When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy.
Let there be light: Chemists develop magnetically responsive liquid crystals
Chemists at the University of California, Riverside have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research opens ...
Flexible, transparent thin film transistors raise hopes for flexible screens
(Phys.org) —The electronics world has been dreaming for half a century of the day you can roll a TV up in a tube. Last year, Samsung even unveiled a smartphone with a curved screen—but it was solid, not ...
Lab unzips nanotubes into ribbons by shooting them at a target
(Phys.org) —Carbon nanotubes "unzipped" into graphene nanoribbons by a chemical process invented at Rice University are finding use in all kinds of projects, but Rice scientists have now found a chemical-free ...
Self-cleaning, antireflective coating mimicks the structure of moth eyes
(Phys.org) —Porous films, which use similar properties to those seen in moth eyes in combination with nanoparticles, are being developed into robust, self-cleaning antireflective coatings for use on both ...
New type of solar structure cools buildings in full sunlight
(Phys.org) —A Stanford team has designed an entirely new form of cooling panel that works even when the sun is shining. Such a panel could vastly improve the daylight cooling of buildings, cars and other ...
