Renewables could drastically cut tailpipe emissions
(PHYSorg.com Chemistry)

Switching to renewable fuels could significantly lower exhaust emissions of toxic nitrogen oxides (NOx) as well as curbing global greenhouse gas emissions. Researchers at KAUST have combined computer analysis with laser-based NOx concentration measurements to understand NOx production pathways in different fuel types. The results may inspire new ways to mitigate NOx emissions, the researchers say.
