Reduction Methods. The approaches to the reduction of oxygen in graphene oxide are varied, and include high temperature treatment (>1000 C), chemical reduction, and optical- or microwave-assisted ...

However, recent research has indicated that Pt nanoclusters (Pt NCs) have higher oxygen reduction reaction (ORR) activity than Pt NPs, i.e., they have higher performance. Thus far, the reason for ...

Hypoxemia refers to a reduction in the amount of oxygen in the bloodstream. This means that the level of oxygen falls below the normal range and there is not enough present in the blood.

"The reduction of oxygen provides the largest free energy release per electron transfer, except for the reduction of fluorine and chlorine," University of Washington professor David Catling and ...

Researchers use models to understand how Earth's atmosphere will be in the coming billion years, and the results indicate it would have no place for humans ...

We think of oxygen as life, sustenance, a literal breath of fresh air. But it's actually a very reactive element. Anyone who's burned a log has witnessed this firsthand. So why do so many life ...
