LARA Opens the Way for More Effective Carbon Trading, Drug Development and Carbon Dating

Carbon offsets increasingly are becoming a major component in the arsenal for reducing global warming. Even Bon Jovi, the Rolling Stones and the Dave Matthews Band are doing it: acquiring carbon offsets to reduce the carbon footprint of their tours. As more organizations and businesses start trading in carbon offsets, the need for accurate measurements of carbon emissions also is becoming critically important for fair and exact exchanges.

A Cheap Alternative to Expensive Silicon Solar Cells

In a paper published online June 29 in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells. This breakthrough in efficiency without the use of volatile organic solvents will make it possible to pursue large scale, outdoor practical application of lightweight, inexpensive, flexible dye-sensitized solar films that are stable over long periods of light and heat exposure.
