Graphene-based nano-antennas may enable networks of tiny machines
Atlanta GA (SPX) Dec 14, 2013
Networks of nanometer-scale machines offer exciting potential applications in medicine, industry, environmental protection and defense, but until now there's been one very small problem: the limited capability of nanoscale antennas fabricated from traditional metallic components. With antennas made from conventional materials like copper, communication between low-power nanomachines would be virtually impossible. But by taking advantage of the unique electronic properties of the material known as ... read more

Oregon scientists offer new insights on controlling nanoparticle stability University of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to ma ... more		Less is more with adding graphene to nanofibers Figuring that if some is good, more must be better, researchers have been trying to pack more graphene, a supermaterial, into structural composites. Collaborative research led by University of Nebra ... more		Scientists scale terahertz peaks in nanotubes Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they're metallic by nature or doped. In new research, the Rice University laboratory of p ... more
				Berkeley Lab Researchers Discover Nanoscale Shape-Memory Oxide Listen up nickel-titanium and all you other shape-memory alloys, there's a new kid on the block that just claimed the championship for elasticity and is primed to take over the shape memory apps mar ... more		Stanford engineers show how to optimize carbon nanotube arrays for use in hot spots When engineers design devices, they must often join together two materials that expand and contract at different rates as temperatures change. Such thermal differences can cause problems if, for ins ... more

Laser light at useful wavelengths from semiconductor nanowires Thread-like semiconductor structures called nanowires, so thin that they are effectively one-dimensional, show potential as lasers for applications in computing, communications, and sensing.
