Nanowires More Efficient Than Solar Cells
2013-01-18 19:23:18

Lee Rannals for redOrbit.com — Your Universe Online A team from Lund University in Sweden wrote in the journal Science about how nanowires could eventually make way for more efficient solar cells. Scientists have been studying solar cell nanowires more and more, and until now, the dream figure was ten percent efficiency. However, the Swedish researchers were able to report an efficiency of 13.8 percent. Nanowires are made of the semiconductor material indium phosphide and work...

Strongest, Lightest Glass Nanofibres In The World Developed By Southampton Scientist
2013-01-10 12:30:07

University of Southampton The University of Southampton's Optoelectronics Research Centre (ORC) is pioneering research into developing the strongest silica nanofibres in the world. Globally the quest has been on to find ultrahigh strength composites, leading ORC scientists to investigate light, ultrahigh strength nanowires that are not compromised by defects. Historically, carbon nanotubes were the strongest material available, but high strengths could only be measured in very short...

Scientists Create Powerful, Microscale Actuator That Can Flex Like A Finger
2012-12-17 11:06:55

Lawrence Berkeley National Laboratory Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have developed an elegant and powerful new microscale actuator that can flex like a tiny beckoning finger. Based on an oxide material that expands and contracts dramatically in response to a small temperature variation, the actuators are smaller than the width of a human hair and are promising for...

Berkeley Lab scientists develop a new nanotech tool to probe solar-energy conversion If nanoscience were television, we'd be in the 1950s. Although scientists can make and manipulate nanoscale objects with increasingly awesome control, they are limited to black-and-white imagery for examining those objects. Information about nanoscale chemistry and interactions with light–the atomic-microscopy equivalent to color–is tantalizingly out of reach to all but the most persistent...

Semiconductors Made Of Graphene
2012-10-01 04:54:45

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the Norwegian University of Science and Technology (NTNU) have developed a thinner, more flexible, less expensive type of semiconductor that uses graphene instead of silicon. Typically, the silicon-based semiconductors used in commercial technology are "rigid, opaque, and about half a millimeter thick," according to Gizmag's Ben Coxworth. However, a new process developed by Dr. Helge Weman, Professor...

First All-optical Nanowire Switch Made By Penn Researchers
2012-09-12 07:36:11

Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1´s and 0´s were represented by bursts of light, instead of electricity. Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that...

Nanowires Grown On Graphene Could Transform Semiconductor Industry
2012-09-11 14:16:44

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Norwegian University of Science and Technology (NTNU) have patented and are commercializing a technology that allows gallium arsenide (GaAs) nanowires to be grown on graphene, a new hybrid material with exceptional optoelectronic properties, in a breakthrough that could fundamentally change the semiconductor industry. The patented method of growing semiconductor nanowires on atomically thin graphene uses...

Harvard scientists have, for the first, time created a type of "cyborg" tissue by embedding a three-dimensional network of functional, bio-compatible nanoscale wires into engineered human tissues. As described in a paper published August 26 in Nature Materials, a multi-institutional research team led by Charles M. Lieber, the Mark Hyman, Jr. Professor of Chemistry at Harvard and Daniel Kohane, a Harvard Medical School professor in the Department of Anesthesia at Children's Hospital Boston...
