Suits said the findings have implications for how molecular oxygen (O2) may have formed in the Earth’s outer atmosphere, in other planetary atmospheres, and perhaps in the outflows of dying ...

“Because of oxygen’s chemical advantages and the history of complex life on earth is so intertwined with oxygen levels,” said Catling, “I think E.T. would also breathe oxygen.” ...

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.

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.

The scientists who formed the oxygen-27 and oxygen-28 isotopes went through a lot of trouble to get this done. They had to start by taking some calcium-48 and firing it at a ball of beryllium ...

A team of chemists at the Korea Advanced Institute of Science and Technology has succeeded in pulling an oxygen atom from a molecule and replacing it with a nitrogen atom. In their study ...

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 ...

In the meantime, an individual O2 molecule can hang around in the Martian atmosphere for at least 10 years, if not several decades. This sunlight-formed O2 makes up about 0.13 percent of the red ...

Molecular oxygen (O2) is key to all life on earth, as it is constantly cycled via photosynthesis and cellular respiration. Substantial scientific effort has been devoted to understanding every part of ...

Colorado State University chemists have achieved a new feat in the realm of chemical design and synthesis: They’ve helped create the first example of a synthetic molecule, with an asymmetric ...
