The winner of the 2010 Feynman Prize for Theory is Gustavo E Scuseria (Rice University) for his development of quantum mechanical methods and computational programs that make it possible to carry out accurate theoretical predictions of molecules and solids, and their application to the chemical and electronic properties of carbon nanostructures. The annual Feynman Prizes are leading to the eventual awarding of
The duration of the fellowship is three months. And last date for submitting the application is January 31, 2011. Feynman Prizes in Nanotechnology Awarded The Foresight Institute, a nanotechnology education and public policy think tank based in Palo Alto, has announced the winners of the prestigious 2010 Foresight Institute Feynman Prizes in Nanotechnology. Established in 1993 in honor of Nobel Prize winner Richard Feynman, two $5,000 prizes are awarded in two categories, theory and experiment, to recognise researchers whose recent work has most advanced the field toward the achievement of Feynman's vision for nanotechnology: molecular manufacturing, the construction of atomically-precise products through the use of molecular machine systems. The winner of the 2010 Feynman Prize for Experimental work is Masakazu Aono (MANA Center, National Institute for Materials Science, Japan) in recognition of his pioneering and continuing work, including research into the manipulation of atoms, the multiprobe STM and AFM, the atomic switch, and single-molecule-level chemical control including ultradense molecular data storage and molecular wiring; and his inspiration of an entire generation of researchers who have made their own ground-breaking contributions to nanotechnology.

demonstrated how a nanoscoop electrode could be charged and discharged at a rate 40 to 60 times faster than conventional battery anodes, while maintaining a comparable energy density. This stellar performance, which was achieved over 100 continuous charge/discharge cycles, has the team confident that their new technology holds significant potential for the design and realization of high-power, highcapacity Li-ion rechargeable batteries. “Charging my laptop or cell phone in a few minutes, rather than an hour, sounds pretty good to me,” said Koratkar, a professor in the Department of Mechanical, Aerospace, and Nuclear Engineering at Rensselaer.“By using our nanoscoops as the anode architecture for Li-ion rechargeable batteries, this is a very real prospect. Moreover, this technology could potentially be ramped up to suit the demanding needs of batteries for electric automobiles.”
'Nanoscoops' improve 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. The Rensselaer research team, led by Professor Nikhil Koratkar,

Batteries for all-electric vehicles must deliver high power densities in addition to high energy densities, Koatkar said. These vehicles today use supercapacitors to perform power-intensive functions, such as starting the vehicle and rapid acceleration, in conjunction with conventional batteries that deliver high energy density for normal cruise driving and other operations. Koratkar said the invention of nanoscoops may enable these two separate systems to be combined into a single, more efficient battery unit.
