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...

Surprising breakthrough could bolster quantum photonics, solar cell efficiency Scientists from the U.S. Department of Energy´s National Renewable Energy Laboratory and other labs have demonstrated a process whereby quantum dots can self-assemble at optimal locations in nanowires, a breakthrough that could improve solar cells, quantum computing, and lighting devices. A paper on the new technology, “Self-assembled Quantum Dots in a Nanowire System for Quantum Photonics,”...

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...

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...

Word of the Day
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
