Sodium-based batteries are particularly attractive: Sodium is a cheap, nontoxic, and abundant element that is uniformly distributed around the world and therefore would be ideal as a transport ion for rechargeable batteries.

A technique for creating a new molecule that structurally and chemically replicates the active part of the widely used industrial catalyst molybdenite has been developed by researchers with the U.S.

MIT team uncovers a reason why the hottest new material for rechargeable batteries works so well.

Typically, a solar cell generates a single electron for each photon captured. However, by adding pentacene, an organic semiconductor, the solar cells can generate two electrons for every photon from the blue light spectrum. This could enable the cells to capture 44% of the incoming solar energy.

almost certainly under-stated conclusion that it has "found that since Obama took office three years ago, between 282 and 535 civilians have been credibly reported as killed including more than 60 children." And targeting rescuers and funeral attendees of your victims is quite the opposite of keeping the drone program on a "very tight leash." 

(PhysOrg.com) -- Researchers from the National Renewable Energy Laboratory (NREL) have reported the first solar cell that produces a photocurrent that has an external quantum efficiency greater than 100 percent when photoexcited with photons from the high energy region of the solar spectrum
