Figure 6
Circularity versus the size of silica particles. Data from analysis of FESEM images. Continuous curves represent the fit for each sample. Diagram (a) shows a rough decreasing trend, which it is difficult to fit using an exponential model [e.g. in (c) for sample S1] or a power-law model [see (b) for sample S52]. Overall, errors in circularity (1σ SD) are less than 3%; see more details in Section S5. In (b) and (c), bins for sizes larger than 500 nm were discarded since they concentrated a scarce quantity of particles.
