I have demonstrated the ability of the COP model and the accompanying graphical interpretation to probe nucleation and growth kinetics from macroscopic quantities, even where a linear model sufficiently describes the data. I are able to test kinetic models of nucleation, ruling out classical nucleation theory for the nucleation of S 8 sols, even without sufficient data to determine the size of critical nuclei precisely. This is extremely important since even several orders of magnitude of data were insufficient to obtain estimated ranges for both nuclei size and attachment frequencies which did not include zero and/or infinite. Furthermore, the graphical interpretation shows that growth controls the final number of nuclei when the solute generation rate is sufficiently small, but both growth and nucleation are important at larger values (especially where growth is slow). This makes the COP model crucial for size control of quantum dots produced via LaMer burst nucleation since there will necessarily be sizes of nuclei which cannot be predicted using a linear model.
