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).

Airfields for ultra-light aircraft are typically constructed on level ground ? and so are wind farms. However, do wind power plantsgenerate turbulence that could endanger lightweight planes? A simulation can compute how these power plants influence aircraft at various wind speeds and wind directions.
