Size and composition of carbon nanoparticles emitted by combustion systems-(legge 5 Regione Campania)

There is a constant need of new researches on combustion-generated particulate and techniques able to monitor an extended size range down to the smallest particles in order to provide exhaustive monitoring of air quality and provide new guidelines to update regulatory standards for limiting particulate emission. The main objective of the research program was to extend the characterization of particulate matter formation and growth in flame and in the exhaust of combustion system. 1) Development and characterization of a sampling method able to collect nanometric particulate matter from laboratory and practical combustion systems. 2) Sampling and analysis of the nanometric particulate at the exhausts of practical (domestic appliance and engines) systems. 3) Chemico-physical analysis of the sampled nanometric particulate matter by "ex situ" techniques. 4) Investigation of specific properties of combustion nanoparticles, which are of particular interest for environmental issues. Specifically: interaction of particles with water, which is of interest for health issue and climate effect related to cloud formation, and optical properties like emissivity, which are of interest for climate effect related to radiative balance.
