So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that maintain life, said Donald Canfield, a geobiologist at the University of ...

Think of a metal with paint on it, like an automobile or a pipeline carrying natural gas. The paint or polymer coating ...

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 ...

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 ...

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.

This research offers a cost-effective and efficient alternative to noble metal-based catalysts, addressing the critical need ...

‘Namely, through the reaction of helium ions [He+] with CO2.’ In other, far less complicated terms, Tian and Hu’s study found that there’s a chance life-sustaining oxygen can form on ...
