Scientists precisely measure the charge state of manganese

Most atoms lose or gain just a few negatively charged electrons from their surroundings, but not manganese. This element can donate up to seven electrons or wrench as many as three electrons away, abilities that can have ...

ChemCam findings hint at oxygen-rich past on Mars

The discovery of manganese oxides in Martian rocks might tell us that the Red Planet was once more Earth-like than previously believed. A new paper in Geophysical Research Letters reveals that NASA's Curiosity rover observed ...

Could bread mold build a better rechargeable battery?

You probably don't think much of fungi, and especially those that turn bread moldy, but researchers reporting in the Cell Press journal Current Biology on March 17, 2016 have evidence that might just change your mind. Their ...

Bioinspired catalyst splits water

Plants use photosynthesis to convert carbon dioxide and water into sugars and oxygen. The process starts in a cluster of manganese, calcium and oxygen atoms at the heart of a protein complex called photosystem II, which splits ...

Treated fibers clean dye-polluted waters

(Phys.org) —A cheap and simple process using natural fibers embedded with nanoparticles can almost completely rid water of harmful textile dyes in minutes, report Cornell and Colombian researchers who worked with native ...

Morphing manganese

An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known, according to a study led by University of Delaware researchers that was ...
