The widespread use of fuel cells is currently limited by the lack of efficient and cost-effective catalysts for the oxygen reduction reaction. Iron-based non-precious metal catalysts exhibit promising ...

Researchers defined the structure of a substrate-bound iron 2-oxoglutarate (Fe/2OG) enzyme to explore whether these enzymes could be used to create a wide array of molecules. They saw that Fe/2OG ...

Fuel cells and metal-air batteries are considered the future of clean energy technology, but they rely on one critical reaction—the oxygen reduction reaction (ORR)—to convert energy efficiently.

As the climate crisis becomes a part of daily life with unprecedented heat waves and cold snaps, technology to effectively remove greenhouse gases is emerging as a critical global challenge. In ...

New light has been shed on a curious group of bacteria that use iron in much the same way that animals use oxygen: to soak up electrons during biochemical reactions. When organisms -- whether bacteria ...

MADISON, Wis. -- A pair of papers from a UW-Madison geoscience lab shed light on a curious group of bacteria that use iron in much the same way that animals use oxygen: to soak up electrons during ...
