Metals react differently. Some are very reactive and others are unreactive. Observations of reactions can be used to put metals into an order of reactivity. For example, copper is unreactive so it can ...

Scientists have long noted with interest that in one of nature's crucial chemical reactions—the oxygen evolution reaction—it ...

During evolution, one of the main developments of organisms was the ability to extract oxygen from the environment and carry it to each cell in multicellular organisms in time through metabolism. Life ...

Singlet oxygen can be damaging in both cells and batteries but it has taken almost 60 years to work out exactly when it shows ...

Sometimes, less really is more. By removing oxygen during synthesis, a team led by materials scientists at Penn State has ...
