Catalytic tandem reaction for conversion of lignin and bio-oil by hydroxylation of phenols to form arenes

(Phys.org) —Biomass, which is useful as a supplement or replacement for petroleum, is processed in biorefineries and can be used as fuels or starting materials for the production of chemicals. However, the high oxygen content ...

How the newest diesel engines emit very little greenhouse gas nitrous oxide

(Phys.org) —The newest catalytic converters in diesel engines blast away a pollutant from combustion with the help of ammonia. Common in European cars, the engines exhaust harmless nitrogen and water. How they do this hasn't ...
