Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly ...

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 ...

Researchers at MIT have created an unusual oxygen-rich molecule that scientists have tried to ...

Scientists have found that molecular oxygen around comet 67P is not produced on its surface, as some suggested, but may be from its body. The European Space Agency’s Rosetta spacecraft escorted comet ...
