Speeding the search for better carbon capture

A computer model that can identify the best molecular candidates for removing carbon dioxide, molecular nitrogen and other greenhouse gases from power plant flues has been developed by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), the University of California (UC) Berkeley and the University of Minnesota. The model is the first computational method to provide accurate simulations of the interactions between flue gases and a special variety of the gas-capturing molecular systems known as metal-organic frameworks (MOFs).

Using evolution to understand pollution

Life evolved in a toxic world long before humans began polluting it, according to a University of Massachusetts environmental toxicologist, who added that understanding life's evolutionary response to environmental poisons can help people to fight destructive effects.

New process doubles production of alternative fuel while slashing costs

A new discovery should make the alternative fuel butanol more attractive to the biofuel industry. University of Illinois scientist Hao Feng has found a way around the bottleneck that has frustrated producers in the past and could significantly reduce the cost of the energy involved in making it as well.

Supercapacitors to provide peak power from fuel cells

European researchers initiated the 'Flexible ecological multipurpose advanced generator' (FEMAG) project to develop a novel energy generator. The design integrated a fuel cell with supercapacitors to handle power peaks and thus enable a durable and flexible power supply for small, portable non-automotive devices.
