Carbonaceous nanoparticles formed from laser-heated soot aggregates were studied using electric mobility sizing, transmission electron microscopy, and near-edge x-ray absorption fine structure spectroscopy. The results suggest that nanoparticle formation proceeds through volatilization/re-condensation of carbon clusters.
