Abstract

Carbonaceous nanoparticles (<35 nm) formed from laser-heated soot aggregates were studied using electric mobility sizing, transmission electron microscopy (TEM), and near-edge xray absorption fine structure (NEXAFS) spectroscopy. Experimental and modeling results suggest that nanoparticle formation proceeds through volatilization/re-condensation of carbon clusters.
