A protective shield for sensitive enzymes in biofuel cells

An international team of researchers has developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. The enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable ...

Modern alchemists are making chemistry greener

Ancient alchemists tried to turn lead and other common metals into gold and platinum. Modern chemists in Paul Chirik's lab at Princeton are transforming reactions that have depended on environmentally unfriendly precious ...

New natural gas catalyst would boost clean transportation

Thanks to advances in drilling technology, there is enough natural gas in the U.S. to last well into next century and beyond. This has renewed the idea of using inexpensive, domestically produced natural gas as a transportation ...

Hydrogen extraction breakthrough could be game-changer

Researchers at KTH Royal Institute of Technology have successfully tested a new material that can be used for cheap and large-scale production of hydrogen – a promising alternative to fossil fuel.

Recruiting manganese to upgrade carbon dioxide

OIST researchers developed simple catalysts based on Earth-abundant manganese to use carbon dioxide for energy storage or turn it into useful chemicals for the industry.

Scientists make vanadium into a useful catalyst for hydrogenation

Just as Cinderella turned from a poor teenager into a magnificent princess with the aid of a little magic, scientists at the U.S. Department of Energy's Argonne National Laboratory have transformed a common metal into a useful ...

New insights into early terrestrial planet formation

Scientists at Tokyo Institute of Technology have demonstrated that the relatively high levels of precious metals (gold, platinum, etc.) in the Earth's mantle likely originated from one large-scale planetary impact prior to ...
