2 Americans, a Dane win 2022 Nobel Prize in chemistry

The Nobel Chemistry Prize was on Wednesday awarded to a trio of chemists from the US and Denmark who laid the foundation for a more functional form of chemistry.

Americans Carolyn Bertozzi and Barry Sharpless, together with Denmark's Morten Meldal, were honoured "for the development of click chemistry and bioorthogonal chemistry," the jury said.

The award marks the second Nobel for 81-year-old Sharpless, who won the chemistry Nobel in 2001.
