Comparison between the diffraction pattern of a spherical Pt nanoparticle of radius 4.71 nm carved from an infinite crystal structure (blue dots) and the pattern simulated by TOPAS using the WPPM_SR_Sphere macro (red line). The unit-cell parameter used for the latter was 3.9115 Å, obtained by refining the pattern of the corresponding relaxed particle with constant values of the model parameters (see Fig. 16 ![]() |
