Soot Morphology and Nanostructure in Complex Flame Flow Patterns via Secondary Particle Surface Growth.
TLDR
It is proposed that due to the spheroidal shape of the large primary particles, the secondary surface growth is primarily a result of polyaromatic hydrocarbon (PAH) condensation during re-entrainment of mature soot into the fuel-rich region followed by subsequent liquid layer carbonization in the high-temperature environment of the flame front.About:

Nanostructure Transition of Young Soot Aggregates to Mature Soot Aggregates in Diluted Diffusion Flames.
TL;DR: The structural properties of soot produced in diffusion flames are analyzed to elucidate the formation of mature aggregates from large young particles, and transmission electron microscopy shows that young soot aggregates contain a higher fraction of shorter fringes and highly curved aromatics.
