How a molecular motor moves in a network

A new study determines the efficiency of a single-molecule heat engine by considering a series of ratchets that transfer energy along a network.

Catalyst can control methane emissions in natural gas engines

A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, the advance in single atom ...

A breakthrough in sustainable methane utilization technology

99.5% of combustible ice is methane, making it an important reserve energy source. It is inferred that the reserves of combustible ice in the South China Sea amount to the equivalent of at least 80 billion tons of oil.

New study shows how Chicago pollution varies by neighborhood

If you live along one of the major interstate highways running through Chicago or directly next to Lake Michigan, you are regularly exposed to more air pollution than the rest of the city, a new Northwestern University study ...
