University of Cincinnati research describes discovery of a new structure that is a fundamental game changer in the physics of semiconductor nanowires. There´s big news in the world of tiny things. New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts...

Nanowires May Mean More Efficient, Cheaper Solar Panels
2013-04-08 19:16:36

Enid Burns for redOrbit.com — Your Universe Online Nanowires could be the answer for constructing solar panels with less materials and lower costs. Researchers at the Ecole Polytechnique Federale De Lausanne (EPFL) are working on new technology to advance solar panels. New research on tiny filaments called nanowires has made some promising findings. Influenced by nature, researcher Anna Fontcuberta i Morral looked at how trees in a forest stand upright to collect energy from the...

Penn Engineers Have Enabled 'Bulk' Silicon Enabled To Emit Visible Light For The First Time
2013-03-28 12:43:54

University of Pennsylvania Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass those limitations, but the components of such computers require semiconductors that can emit light. Now, research from the University of Pennsylvania has enabled "bulk" silicon to emit broad-spectrum, visible light for the first time, opening the possibility...

Super-Efficient Nanowires Could Be Future Of Solar Energy
2013-03-25 10:40:52

Brett Smith for redOrbit.com - Your Universe Online Extremely thin nanowires are expected to revolutionize the field of electronics, and a new study in the journal Nature Photonics shows that they could have an impact on solar energy production as well. According to the study, researchers at the Niels Bohr Institut in Denmark and Switzerland´s École polytechnique fédérale de Lausanne (EPFL) have been able to use a single nanowire to...

Slender bacterial nanowires require certain key amino acids in order to conduct electricity, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology, on Tuesday, March 12. In nature, the bacterium Geobacter sulfurreducens uses these nanowires, called pili, to transport electrons to remote iron particles or other microbes, but the benefits of these wires can also be harnessed by humans for use in fuel cells or...

New design uses silicon nanoparticles to improve capacity and recharge more quickly Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance. The new batteries–which could be used in anything from cell phones to hybrid cars–hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The design, currently under a...

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...
