Cross-sections of Au561 nanoclusters at elevated temperatures. a A free and b a frozen-facet nanocluster at 627 °C. Green spheres denote atoms that are recognized as fcc, while grey spheres are atoms found to be non-crystalline. The bottom layer in (b) is the frozen layer. At this temperature the core is approximately double in size in (b) compared with (a) (85 atoms and 43 atoms, respectively) and displaced towards the frozen facet
