Combustion processes result in a wide range of products. Recently much attention is being devoted to the nanosized products of combustion, as their presence within the atmosphere has very profound impact not only from the climatologic point of view but also from a medical one, as many epidemiological studies outline the direct correlation between high concentration of carbonaceous nanoparticulate and deseases.
Samples from premixed laminar ethylene- air flame operating in different conditions from no-sooting to slightly sooting have been collected.
Different optical techniques coupled with AFM-microscopy are here employed for getting a better insight on the chemical and morphological nature of these nanoparticulates.
