In situ transmission electron microscopy (TEM) imaging of platinum nanoparticles rotating freely in liquid. (A) Schematic representation of individual rotating platinum nanoparticles in a graphene liquid cell (GLC). The bottom represents a series of snapshots of the nanocrystal.(B and C) Two-dimensional snapshots are used to reconstruct the 3D images of two different particles. Scale bars are 0.5 nanometers.
