Dynamic catalytic converters for clean air in the city

Reducing pollutant emission of vehicles and meeting stricter exhaust gas standards are major challenges when developing catalytic converters. A new concept might help to efficiently treat exhaust gases after the cold start ...

Scientists rev up speed of bionic enzyme reactions

Bionic enzymes got a needed boost in speed thanks to new research at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). By pairing a noble metal with a natural enzyme, scientists created a hybrid ...

New nanoparticle catalysts could reduce need for precious metals

Materials that speed up a chemical reaction without getting consumed in the process, known as catalysts, lie at the heart of many technologies, from vehicle emissions-control systems to high-tech devices such as fuel cells ...
