In this study the physicochemical evolution of soot particles in a laminar premixed flame has been investigated. The evolution of the particle size distribution as function of the different heights above the burner has been explored in conjunction with changes of particle chemical/physical properties retrieved by Raman and Electron Paramagnetic Resonance spectroscopy. In addition, the results obtained by Raman spectroscopy on flame formed soot particles were compared to those obtained by analyzing some standard carbon-based materials such as commercial carbon black, activated carbon, disordered graphite and highly oriented pyrolytic graphite.

Abstract
In this study the physicochemical evolution of soot particles in a laminar premixed flame has been investigated. The evolution of the particle size distribution as function of the different heights above the burner has been explored in conjunction with changes of particle chemical/physical properties retrieved by Raman and Electron Paramagnetic Resonance spectroscopy. In addition, the results obtained by Raman spectroscopy on flame formed soot particles were compared to those obtained by analyzing some standard carbon-based materials such as commercial carbon black, activated carbon, disordered graphite and highly oriented pyrolytic graphite.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
