Scientists develop silicon cells capable of absorbing infrared radiation from the sun

Posted by External 22 days ago General
http://feeds.sciencedaily.com — Researchers have developed a silicon photovoltaic cell capable of turning infrared radiation into electricity. The sun is an inexhaustible source of energy which well-exploited, could solve many of the energy suply problems we have today. The photovoltaic cell, commonly known as solar cell, is a device capable of turning solar light into electricity. However, there are many obstacles that prevent Read More

Radiation damage at the root of Chernobyl's ecosystems

Posted by External 29 days ago General
http://feeds.sciencedaily.com — Radiological damage to microbes near the site of the Chernobyl disaster has slowed the decomposition of fallen leaves and other plant matter in the area, according to a new study. The resulting buildup of dry, loose detritus is a wildfire hazard that poses the threat of spreading radioactivity from the Chernobyl area. Read More

Earth's radiation belt: Van Allen probes reveal zebra stripes in space

Posted by External 29 days ago General
http://feeds.sciencedaily.com — Scientists have discovered a new, persistent structure in one of two radiation belts surrounding Earth. NASA's twin Van Allen Probes spacecraft have shown that high-energy electrons in the inner radiation belt display a persistent pattern that resembles slanted zebra stripes. Surprisingly, this structure is produced by the slow rotation of Earth, previously considered incapable of affecting the m Read More

Solar cells utilize thermal radiation

Posted by External 152 days ago General
http://feeds.sciencedaily.com — Thermal radiation from the sun is largely lost on most silicon solar cells. Up-converters transform the infrared radiation into usable light, however. Researchers have now for the first time successfully adapted this effect for use in generating power. Read More

Solar energy: Improved data mining tool for hourly solar radiation

Posted by External 159 days ago General
http://feeds.sciencedaily.com — Solar energy is free, clean, and usually available in abundance. However, solar radiation is also less predictable than many kinds of fossil fuel. Researchers have now developed a model that allows a more accurate prediction of hourly solar radiation. Read More

Earth's radiation belts more complicated than thought

Posted by External 206 days ago General
http://www.enn.com — The Earth is circled by belts of electrons and ions that have been the subject of study for decades. Now, a new study casts light on details of these radiation belts that eluded scientists. Since the discovery of the Van Allen radiation belts in 1958, space scientists have believed these belts encircling the Earth consist of Read More

Formation of unusual ring of radiation around Earth explained

Posted by External 207 days ago General
http://feeds.sciencedaily.com — Since the discovery of the Van Allen radiation belts, scientists believed these belts consisted of two rings of highly charged particles. In February, scientists reported the discovery of a previously unknown third radiation ring -- a narrow ring that briefly circled the Earth for a month. Space scientists have successfully modeled and explained the unprecedented behavior of this third ring, and Read More
