“…Initial electrophoresis experiments of Schmidt 17 with Au nanocrystals indicated the formation of (Au 13 ) 13 types of superclusters. Further, a high mass secondary ion peak observed also seemed to support this contention. , Theoretical calculations based on the embedded atom method have indicated that such a growth of metal nanocrystals is indeed a possibility . In Figure , is shown a schematic illustration of a (M 55 ) 55 giant cluster.…”

Magic nuclearity giant clusters formed by the mesoscale self-assembly of Pd nanocrystals of 2.5 nm diameter (nuclearity, ∼561) have been identified by transmission electron microscopy. The clusters have discrete diameters, corresponding to those expected for magic nuclearity of 13, 55, 147, 309, 561, and 1415 and corresponding to closed shells of 1, 2, 3, 4, 5, and 7, respectively. Imaging at different tilt angles has provided confirmation of the spherical nature of these giant clusters. Giant clusters of magic nuclearity have also been found with Pd nanocrystals of ∼3.2 nm diameter (nuclearity, ∼1415).

“…Superclusters It has been proposed that self-similarity in metal nanocrystal organization would manifest in the form of a giant cluster whose shape and size are direct consequences of the nanocrystals themselves [147]. The invariance of the shell effects in metal nanocrystals with scaling is shown schematically in Figure 4.20.…”
