Diurnal oxidation for manganese minerals in the Arctic Ocean

Manganese is an important element for all life, but it plays an especially critical role in photosynthesis, in which it is the catalyst for splitting oxygen molecules from water. In the ocean—where phytoplankton is a key ...

Using radicalized NOₓ derivatives supported on metal oxides

NOX (X=1 or 2) emitted from stationery/mobile sources are conventionally deemed as notorious, anthropogenic precursors of ultrafine particulate matters (PM2.5) because NOX can undergo a series of SO2-assisted photochemical ...

Bacteria with a metal diet discovered in dirty glassware

Caltech microbiologists have discovered bacteria that feed on manganese and use the metal as their source of calories. Such microbes were predicted to exist over a century ago, but none had been found or described until now.

Engineered sand zaps storm water pollutants

University of California, Berkeley, engineers have created a new way to remove contaminants from storm water, potentially addressing the needs of water-stressed communities that are searching for ways to tap the abundant ...

A step closer to sustainable energy from seawater

The research group led by Leiden chemist Marc Koper has discovered a catalyst that minimizes the production of chlorine gas during salt water electrolysis. The invention can enable the direct production of hydrogen from seawater. ...
