  In the supporting information file of the article Controlled Formation and
Growth Kinetics of Phase-Pure, Crystalline BiFeO3 Nanoparticles (Crystal Growth
& Design 2019), there is a description on how to use Scherrer equation for in
situ X-ray diffraction analysis of crystallization processes investigated in
the article. That description led to a necessary revaluation on the current
understanding of the usage of Scherrer equation for analyzing size
distributions, as discussed in this work.
