Most phosphorus in the environment is in an organic form that plants cannot directly use, and traditional understanding suggested only enzymes could convert it into the bioavailable inorganic form.

A kinetically controlled synthesis has yielded a novel strontium-iron oxide with an unusual structure. The study, reported in Nature (2007, 450, 1062), may lead to new types of materials with useful ...

CHICAGO — One of the more recent developments in sunscreen technology is the addition of iron oxide to mineral sunscreens. Iron oxide is "an excellent pigment" that absorbs and blocks visible light, ...
