Fig. 1: Size distribution and statistical analysis of the isomer proportions for Silver nanoparticles exposed to air on amorphous carbon.

a Number of clusters as a function of size in the range of 1–3000 atoms, split into the different isomer structures observed. b HAADF-STEM images of three different morphologies and their corresponding assignments using the Simulation Atlas method; Face-centred cubic (FCC), decahedral (Dh), and icosahedral (Ih) with 309, 1233, and 835 atoms, respectively. Dotted red lines and red circles area as a guide for the eye. c Statistics for silver cluster symmetries averaged over the whole size range of (a). The U/A assignments correspond to unidentified or amorphous (glassy) structures.
