“…3b, the higher-magnification image of primary particles demonstrates fine structure composed of graphite crystallites with better defined graphene (graphitic) sheets near the particle peripheries than at the centers, which is consistent with the reported fine structure of primary particles. 1,3,[96][97][98][99] The soot generated and studied in our experiments is similar in morphology and size to other flamegenerated soot. Some of the aggregates appeared to have less well-defined primary particles with less turbostratic graphitic order apparent in the fine structure.…”

“…5b) shows the core diameter to decrease from that at the flame root, with increasing temperature in the high temperature zone as well as with decreasing temperature in moving away from the flame root. The latter trend is well explained qualitatively by the equilibrium relations proposed by Hurt et al [49], where the total free energies of the system consisting of the elastic strain energy and the orientational energy is minimized to give the core radius. The core radius is shown to be inversely proportional to (T c -T), where T c is the flame root temperature and T is the temperature at any location along the flame.…”

“…The particle extracted at h = 2 cm (Fig. 6b) shows a clear amorphous core surrounded by crystallites arranged radially in columns [49]. Increasing h to 5 cm (subcooled, temperature = 1,657 K) retains the structure (Fig.…”

“…The latter phenomenon has mechanistic implications for the evolution of soot particle surface morphology, which has been receiving increasing attention [21][22][23][24], as well as to growth of fullerenic materials and carbon nanotubes [25,26].…”
