Anaerobic oxidation of methane (AOM) by sulfate has been recognized as a critical process to maintain this greenhouse gas stability by limiting methane flux to the atmosphere. We show geochemical ...

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 ...

The “blood rain” that turned an Iranian island’s coastline crimson last week was due to the local soil containing high ...

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: ...

Poly-Fe5-PCz is a promising and efficient catalyst for water oxidation, offering a viable solution for hydrogen production and energy storage. A newly developed pentanuclear iron complex (Fe5-PCz ...

A newly developed pentanuclear iron complex (Fe5-PCz(ClO 4) 3) can offer an efficient, stable, and cost-effective solution for water oxidation. By electrochemically polymerizing the complex ...
