First-ever footage of the making and breaking of a chemical bond

YouTube video caption: "A molecule made of two rhenium atoms (dark spots) travels around two carbon nanotubes (lighter lattice of spots), settling into the gap between the nanotubes. When the atoms separate by a larger distance, the bond between the atoms is broken, and then later reforms."

Back story here.

The original research was published last Friday in the journal Science Advances; read the article, entitled "Imaging an unsupported metal-metal bond in dirhenium molecules at the atomic scale," here.
