Synthetic material acts like an insect cloaking device
Nov 03, 2017
Synthetic microspheres with nanoscale holes can absorb light from all directions across a wide range of frequencies, making them a candidate for antireflective coatings, according to a team of Penn State engineers. The synthetic ...
Manganese oxides in treatment system could be mixed blessing
Jan 20, 2017
In a "bad news, good news" scenario, researchers at North Carolina State University have found that some black sludge growing in a water-treatment site could have redeeming benefits.
Scientists precisely measure the charge state of manganese
Sep 05, 2016
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
Jun 27, 2016
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 ...
Researchers examine ways to break down, track synthetic compound in herbicides
Mar 24, 2016
To examine the fate and persistence of glyphosate, one of the most common commercial herbicides used for agricultural and urban applications, and aminomethylphosphonic acid (AMPA), a major byproduct of glyphosate, in soils ...
Could bread mold build a better rechargeable battery?
Mar 17, 2016
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 ...
Neanderthals may have deliberately sourced manganese dioxide for use in fire making
Mar 01, 2016
Several Neanderthal sites in France have yielded large numbers of small black blocs. Neanderthals used these 'manganese oxides' in fire-making and not as previously thought for colouring.
The path to artificial photosynthesis
Jan 21, 2015
Scientists at the Helmholtz Center for Materials and Energy in collaboration with the School of Chemistry and ARC Centre of Excellence for Electromaterials Science at Monash University, Australia, have precisely characterized ...
Bioinspired catalyst splits water
Aug 08, 2014
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 ...
Insights from nature for more efficient water splitting
Jun 30, 2014
Water splitting is one of the critical reactions that sustain life on earth, and could be a key to the creation of future fuels. It is a key in the process of photosynthesis, through which plants produce glucose and oxygen ...
