Single sheets of graphene sandwiched between insulating layers can be used to produce electrical devices with distinctive new properties, researchers at The University of Manchester have shown. Writing in Nature Materials, the scientists show that graphene can be used as a building block to create new 3D crystal structures which are unconfined by what nature…Continue readingGraphene 3D Crystal Structures Demonstrated
Quantum computers should theoretically be capable of performing certain kinds of complex calculations way faster than normal computers. Quantum-based communication could be impenetrable to eavesdropping. But producing quantum components for real-world devices has turned out to be loaded with discouraging challenges. Now, researchers at MIT and Harvard University have achieved a critical long-term goal of…Continue readingSingle Photon Optics Transmitter Slows the Speed of Light
A new design for on-chip laser optical connections which could give a huge speed boost to computers has been unveiled by electrical engineers from the University of Wisconsin-Madison and the University of Texas at Arlington. The findings were published in the Nature Photonics journal’s July 22, 2012 issue. The surface-emitting optically pumped laser measures only…Continue readingPrinted Photonic Crystal Laser on a Chip
A carbon nanotube is 100 times stronger than steel, has 1/6 the weight. But it can be snapped like a twig by a minuscule air bubble. A new study by scientists at Rice University shows just how the much studied nanomaterials can snap when exposed to ultrasonic vibrations in a liquid. “We find that the…Continue readingUltrasonic Energy Blasts Snap Long Nanotubes like Twigs
Ice storms can be disastrous when freezing rain builds up on power lines, trees, roads, and aircraft surfaces. Entire cities can be left without power, heat, water supplies, and cut off from food supplies. Fatal aircraft accidents are still happening, due to ice build-up on control surfaces, even though engineers have been working on the problem for decades. Now researchers at the University of Pittsburgh-have developed an easily applied nanoparticle-based coating that prevents the buildup of ice on solid surfaces.
