So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

Water molecules on the surface of an electrode flip just before they give up electrons to form oxygen – a feat of nanoscale ...

Many metals react with oxygen to form metal oxides. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull ...

Carbon dioxide (CO₂) pollution drives climate change, warming the planet and threatening human survival. Plants naturally ...

Details of the chemical reaction of oxygen with the [Fe-S] cluster reveal how this cofactor is used for oxygen sensing.

When metals react with oxygen, metal oxides are formed. The speed of the reaction depends on the reactivity of the metal. Watch this video for a practical demonstration of reacting metals with oyxgen.

‘Namely, through the reaction of helium ions [He+] with CO2.’ In other, far less complicated terms, Tian and Hu’s study found ...

Limnology and Oceanography, Vol. 61, No. 1 (2016), pp. 61-77 (17 pages) Sandy sediments are now recognized as sites of high carbon turnover enhanced by porewater flow. However, it is unclear how ...

Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...
