The strong influence of nanoparticle properties on scattering data. (a) Structure factor, S(q), curves for a variety of particle shapes and sizes, arranged into a simple cubic lattice (curves are plotted from q = 0 nm−1 to q = 0.4 nm−1, and offset for clarity). The superball parameter p increases down the rows, whereas the particle width varies across the columns (lattice spacing is held constant at a = 85.0 nm, and grain size at [\xi = 7a]). The structural peak intensities vary tremendously based on the nano-object's structure. The sizes are chosen such that the diagonal elements (from lower left to top right) are isovolumetric. Even in this case of matched total scattering power, the scattering results are distinguishable. (b) The intensity of S(q) at the position of the first three peaks (100, 110 and 111) as a function of the shape parameter p, for particles of size 45.0 nm. (c) The intensity of the first three peaks as a function of the particle size (D = 2R), for p = 2.5.
