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 ...

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 ...

The government made the possession of nitrous oxide, or laughing gas, a criminal offence in England and Wales, as part of plans to tackle anti-social behaviour. Its use soared during the pandemic ...

Researchers led by Saudi Arabia’s King Khalid University have developed a 3D-printed anti-reflective coversheet for PV modules. The cover sheet is based on cyclic-olefin copolymers (COC), to ...

A top consideration when choosing a flat iron: “It’s important to me that the flat iron works well with all hair types and offers versatility,” beauty expert Nick Stenson tells PEOPLE.
