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. ...

Synthetic material acts like an insect cloaking device

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 ...

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 ...
