So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

Chlorine and oxygen can generate similar amounts of energy. Fluorine could certainly provide more energy than oxygen, but "fluorine is [...] useless as a biological oxidant because it generates an ...

This result suggested that fluoride was leaching from the PTFE, prompting us to investigate the degradation of PFAS by ball milling it with various negatively charged oxygen-containing ions ...

Credit: ESO/M. Kornmesser Astronomers are gobsmacked by an abundance of oxygen in JADES-GS-z14-0, the earliest (and most distant) known galaxy in the universe. Though elements heavier than ...

Researchers have developed a method to destroy fluorine-containing PFAS (sometimes labelled 'forever chemicals') while recovering their fluorine content for future use. Oxford Chemistry ...

It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis.

Several authors —i. e. Scheler, Arnold, Goldie, Keltner and Ekman— agree that traditionally, in the history of Western ...
