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 ...

The findings from this research can open new avenues to optimize the reaction and lower the cost of clean hydrogen fuel.

Researchers at POSTECH identified a new battery degradation mechanism triggered by deep discharging. Avoiding full discharge ...

Others, meanwhile, propose the oxygen's formation through mechanisms like what's known as the "three-body recombination" ...

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.
