Time-resolved atomic-resolution Brownian tomography of single nanocrystals reveals size-dependent dynamics

We determined atomic structures of 66 temporal structural states, extracted from 15 time-trajectories of individual Pt nanocrystals. Large (478-698 atoms) and small (<300 atoms) nanocrystals show etching that preserves a stable core, whereas mid-sized (351-571 atoms) nanocrystals present dynamics that change the coordination of the core. Time segmented 3D density maps are provided as *mrc files and the associated atomic coordinates are provided as *pdb files.
