(a) SAXS traces of NCs from fraction 8 (green) fitted with a monodisperse orthorhombic (violet) and polydisperse cubic (orange) and orthorhombic (black) models. Best fit was found for an orthorhombic model with 6.5% polydispersity on the edge lengths (fitting results Table S5). (b) Model-free fit of the small angle scattering data along with the NC shape that allowed for the a full 3D reconstruction, shown from 3 sides. Shape found from reconstruction of the scattering pattern agrees with the best-fit model, TEM statistics (Figure 2 d–f), and AUC data (Figure 3d). Measurements and fittings for NCs from fraction 9 can be found in Figure S21.
