Until now, this theory held even for tiny clusters of fewer than about 1000 atoms. (sciencemag.org)
Now, surprised researchers report that tiny clusters of 10 to 30 tin atoms violate this rule: They remain solid at temperatures well above bulk tin's melting point. (sciencemag.org)
Scientists at TU Wien (Vienna), together with colleagues from Utrecht University, can now watch single platinum atoms form tiny clusters. (sciencedaily.com)
