Scientists have discovered a new way to make molecular oxygen (O2) from carbon dioxide (CO2) -- no green plants involved. Their findings could alter our understanding of the Earth’s early ...

Also known as the O2 sensor because O2 is the chemical formula for oxygen, the oxygen sensor monitors how much unburned oxygen is present in the exhaust as exhaust exits the engine.

The oxygen atoms in the O2 molecule are held together by a double covalent bond. Nitrogen (N2), on the other hand, possesses a triple bond. "You would think that the weaker double bond is easier ...

One theory suggested carbon dioxide could potentially be stripped into molecular oxygen (O2) and carbon (C) instead, but "nobody had ever detected" such a process, Ng told Live Science.

A newly discovered way for oxygen to form in carbon-dioxide-rich atmospheres of exoplanets could help guide scientists' search for alien life.

Chemists have synthesized the first stable molecule whose chirality is solely attributed to a stereogenic oxygen, according to a new study (Nature 2023, DOI: 10.1038/s41586-023-05719-z). Though ...

What would you think if they started talking about magic numbers and how a never-before-seen form of oxygen has made them question which numbers are really magic?
