Scientists solve 30-year-old aurora borealis mystery
UCLA space scientists and colleagues have identified the mechanism that triggers substorms in space; wreaks havoc on satellites, power grids and communications systems; and leads to the explosive release of energy that causes the spectacular brightening of the aurora borealis, also known as the... view more (2008-07-25)

Organic solar power
Solar cells made from conventional semiconductor materials such as silicon are becoming increasingly common. By contrast, cells which use organic dyes or electrically conductive plastics are relatively unknown. At the Hanover Fair: prototypes of such cells and possible applications. ----------- If... view more (2002-04-16)

Do the hyper-coordinate planar transition metal atoms exist?
A study reported in Vol 51, Issue 7 (July, 2008) of Science in China Series B: Chemistry has shown that wheel-shaped structures with octa- and enneacoordinate planar cobalt, iron and nickel centered in perfect octagonal and enneagonal boron rings, are stable on corresponding potential... view more (2008-07-01)

Chemical screening system helps evaluate PEM fuel cell materials
Because of their efficiency and reduced pollution, fuel cells offer a promising alternative to traditional power sources in transportation and other applications.
