Extended Data Fig. 8: Patch pattern transition of patchy rhombic dodecahedra.

a, Representative TEM images of patchy small rhombic dodecahedra overlaid with patches colour-coded to their local thickness tloc. Reaction conditions from left to right: [I−] of 0, 0.17, 0.67 and 62.5 µM at a fixed [2-NAT] of 56.7 nM. b,c, Corresponding 3D reconstruction of patchy rhombic dodecahedra from TEM tomography shown along the [100] (b) and [111] directions (c). Scale bars, 20 nm.
