Study reveals how solvent mixtures affect organic solar cell structure

Controlling "mixing" between acceptor and donor layers, or solar cell domains, in polymer-based solar cells could increase their efficiency, according to a team of researchers that included physicists from North Carolina State University. Their findings shed light on the inner workings of these solar cells, and could lead to further improvements in efficiency.

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.
