|Scientists in Beijing have proposed a new type of photo-energy detector -- of infrared pulsed laser light -- using a nanoporous ZnO/n-Si structure that would be relatively simple and inexpensive to develop. Photodetectors are a core component in optoelectronic devices, and this new detector could have expanded applications in the future. ...> Full Article|
|Stanford researchers believe they've discovered a crystal that can form a monolayer three atoms thick. Computer simulations show that this crystal, molybdenum ditelluride, can act like a switch: its crystal lattice can be mechanically pulled and pushed, back and forth, between two different atomic structures -- one that conducts electricity well, the other that does not. The Stanford team hopes experimental scientists will make this semiconductor crystal and use it to fashion flexible electronics. ...> Full Article|
Researchers at the Energy Department's National Renewable Energy Laboratory are turning to extremely tiny tubes and rods to boost power and durability in lithium-ion batteries, the energy sources for cell phones, laptops, and electric vehicles. If successful, the batteries will last longer and perform better, leading to a cost advantage for electric vehicles.

|The antibacterial properties of silver-coated textiles are popular in the fields of sport and medicine. A team at Empa has now investigated how different silver coatings behave in the washing machine, and they have discovered something important: textiles with nano-coatings release fewer nano-particles into the washing water than those with normal coatings. ...> Full Article|
|A group of researchers from Russia, Belarus and Spain, including Moscow Institute of Physics and Technology professor Yury Lozovik, have developed a microscopic force sensor based on carbon nanotubes. The device is described in an article published in the journal Computational Materials Science. ...> Full Article|
|For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate superconducting nanocircuitry. However, the extremely small zinc nanowires he designed did some unexpected -- and sort of funky -- things. ...> Full Article|
