We note that our findings do not significantly affect our understanding of the global distribution of elemental O in the interstellar medium, as O 2 in ice with an abundance of a few per cent relative ...

As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the structure ...

For the first time, astronomers have found molecular oxygen — the same gas humans need to breathe — in a galaxy outside the Milky Way. Oxygen is the third most common element in the cosmos, after ...
