They’re using it to reduce iron oxide to iron, which can easily release the hydrogen by oxidation with water. Their reactor is simplicity itself, a large stainless steel tank filled with ...

In this method, the particles are treated with ammonia gas to get the nitrogen into the crystal structure. Alternatively, iron oxide can be mixed with ammonium nitrate in a planetary ball mill ...

Reduction is the gain of electrons by a substance. It is also the loss of oxygen from a substance. For example, copper(II) oxide can be reduced to form copper when it reacts with hydrogen: ...

In the blast furnace, it is so hot that carbon monoxide can be used, in place of carbon, to reduce the iron(III) oxide: iron(III) oxide + carbon monoxide → iron + carbon dioxide The blast ...

Pure iron is unobtainable by smelting, but small amounts of impurities can make iron many times stronger than it exists in its pure form. Iron oxide compounds, when mixed with aluminum powder, are ...

This oxygen combined with dissolved iron in the sea to form insoluble iron oxide, which sank to the sea floor. As it settled, sheets of red iron oxide were laid down between layers of silica-rich silt ...

More affordable than ever, 3D printers are booming for personal, professional, and educational use. Here's everything to know before you buy one, along with the top models from our hands-on testing.

The government is planning to make possession of nitrous oxide - also known as laughing gas - a criminal offence in England and Wales. Known as NOS, its use as a recreational drug soared during ...
