  1. R e and σ represent average particle radius and geometric standard deviation from TEM size distributions log-normal fit. Number of studied particles and adj. R 2 values can be found from supplementary material. R g is radius of gyration from SLS and R h hydrodynamic radius from DLS. SSABET is specific surface area calculated from nitrogen sorption measurements according to BET theory
