As two isotopically pure silver clusters made of ¹⁰⁷Ag and ¹⁰⁹Ag are mixed, an isotopically mixed cluster of the same entity results, similar to the formation of HDO, from H₂O and D₂O. This spontaneous process is driven by the entropy of mixing and involves events at multiple time scales.Science advanceseaau7555https://www.ebi.ac.uk/biostudies/studies/S-EPMC6314871biostudies-literatureRapid isotopic exchange in nanoparticles.PMC6314871Bandyopadhyay NChakrabarti JParamasivam GPradeep TChakraborty PNatarajan GNag APanwar MKfalseRapid isotopic exchange in nanoparticles.Rapid solution-state exchange dynamics in nanoscale pieces of matter is revealed, taking isotopically pure atomically precise clusters as examples.
