An alternative approach is to reduce iron oxides directly with hydrogen. But most hydrogen is obtained by the reaction of methane with water, or by the electrolysis of water 3. Either way requires two ...

As wireless technologies have become widespread, demand for materials capable of absorbing high-frequency electromagnetic radiation has increased rapidly, especially in extreme, high-temperature ...

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 ...

Alumina (Aluminium Oxide) is the most widely used oxide ceramic material. Its applications are widespread, and include spark plugs, tap washers, abrasion resistant tiles, and cutting tools. Very large ...

Using pictures with atomic resolution, the mechanism of an important chemical reaction has finally be explained: When platinum nanoparticles act as catalysts on an iron oxide surface, the surface ...

Scientists know iron oxide minerals store large amounts of carbon in soils, but lack a detailed, quantitative understanding of the specific chemical mechanisms that allow them to bind such a wide ...
