Fig. 1: The classification and distribution of soot particles in samples.
From: Mechanism of the noncatalytic oxidation of soot using in situ transmission electron microscopy
a The classification of soot particles was based on the nanostructure of soot particles. b The particle size distribution of three types of soot. There were overlaps in the size ranges of different types of particles. It was more accurate to assess the maturity of particles based on their structure than relying on particle size alone. c The maturity of soot samples became younger with the O2/CH4 increased.
