Nano-style sheets may aid health, shield ecosystem

Microscopically, "nanomembrane" sheets made from nylon resemble a tangled web. The tiny iron oxide particles on the fiber surfaces can help clean toxic chemicals from water, but if the particles get separated from the web, ...

Biological wires carry electricity thanks to special amino acids

Slender bacterial nanowires require certain key amino acids in order to conduct electricity, according to a study to be published in mBio, the online open-access journal of the American Society for Microbiology, on Tuesday, ...

What kind of iron is in the Southern Ocean?

(Phys.org)—The Southern Ocean, circling the Earth between Antarctica and the southernmost regions of Africa, South America, and Australia, is notorious for its High Nutrient, Low Chlorophyl zones, areas otherwise rich in ...

Designer particles stand in for layers of subsurface minerals

(Phys.org)—To understand how underground pollutants react with magnetite and other minerals, scientists need an easy-to-use mineral stand-in. An international team led by Pacific Northwest National Laboratory created analogous ...
