Nanonets give rust a boost as agent in water splitting's hydrogen harvest

Nanonets give rust a boost as agent in water splitting's hydrogen harvest ScienceDaily (Feb. 10, 2011) — Coating a lattice of tiny wires called Nanonets with iron oxide (rust) creates an economical and efficient platform for the process of water splitting -- an emerging clean fuel method that harvests hydrogen from water, Boston College researchers report in the online edition of the Journal of the American Chemical Society.

"Nanoscoops" could spark new generation of electric car batteries

"Nanoscoops" could spark new generation of electric car batteries An entirely new type of nanomaterial developed at Rensselaer Polytechnic Institute could enable the next generation of high-power rechargeable lithium (Li)-ion batteries for electric automobiles, as well as batteries for laptop computers, mobile phones, and other portable devices.The new material, dubbed a “nanoscoop” because its shape resembles a cone with a scoop of ice cream on top, can withstand extremely high rates of charge and discharge that would cause conventional electrodes used in today’s Li-ion batteries to rapidly deteriorate and fail. The nanoscoop’s success lies in its unique material composition, structure, and size.

Multi-metal nanoparticles: Digestive ripening is the ticket - Small Times

Multi-metal nanoparticles: Digestive ripening is the ticket - Small Times December 20, 2010) -- A new study from researchers at North Carolina State University sheds light on how a technique that is commonly used for making single-metal nanoparticles can be extended to create nanoparticles consisting of two metals and that have tunable properties. The study also provides insight into the optical properties of some of these nanoparticles.

New ultra-clean nanowires have great potential in solar cell technology and electronics

New ultra-clean nanowires have great potential in solar cell technology and electronics ScienceDaily (Nov. 12, 2010) — New ultra-clean nanowires produced at the Nano-Science Center, University of Copenhagen will have a central role in the development of new high-efficiency solar cells and electronics on a nanometer scale. PhD student Peter Krogstrup, Niels Bohr Institute, in collaboration with a number of well-known researchers and the company SunFlake A/S, is behind the breakthrough. The new findings have recently been published in the journal Nano Letters.
