The so-called antioxidant enzymes that remove the intermediates of oxygen reduction, in particular, superoxide dismutase (SOD), catalase and glutathione peroxidase act in damage control by preventing ...

An interdisciplinary team presents a new class of chemical compounds that can be reversibly oxidized and reduced. The compounds known as 'pyrazinacenes' are simple, stable compounds that consist of a ...

The origin of life from Earth’s primordial chemistry has long fascinated and perplexed us. Generations of scientists have endeavored to understand how complex biochemistry developed from organic ...

More efficient and sustainable energy conversion technologies, among other applications, hinge on lowering the amount of energy needed to trigger specific reactions on the surface of electrodes.

In this reaction, carbon is oxidised because it gains oxygen. At the same time, copper oxide is reduced because oxygen is removed from it.
