By growing arrays of silicon wires in a polymer substrate, researchers have demonstrated what they say are flexible solar cells that absorb up to 96 percent of incident light.
California Institute of Technology (Caltech) researchers said the wires are made up of 98 percent plastic, potentially lowering the cost of photovoltaics by using just 1/50th the amount of semiconductor material used today. In tests, the experimental solar cells demonstrated over 90 percent quantum efficiency, compared with 25 percent for the best silicon solar cells.
Goldman Sachs and other big banks aren't just pocketing the trillions we gave them to rescue the economy - they're re-creating the conditions for another crash
Reports of a UFO hovering over former Conservative Home Secretary Michael Howard's home are among thousands of odd sketches, strange sightings and alleged close encounters detailed in newly released UK documents.
The Food and Drug Administration's warnings cover the drugs Advair, Symbicort, Foradil and Serevent. The FDA said they should be used only by asthmatics who can't control their lung disease with other medications -- and then only for the shortest time possible.
Bassam would have become yet another hidden detail of a non-event. A non-event of the sort that takes place countless times, all the time. Without those non-events, it is impossible to comprehend what life is like under hostile rule.
Almost half of the world's primate species – which include apes, monkeys and lemurs - are threatened with extinction due to the destruction of tropical forests and illegal hunting and trade.
The cost of pollution and other damage to the natural environment caused by the world's biggest companies would wipe out more than one-third of their profits if they were held financially accountable, a major unpublished study for the United Nations has found.
