title: Generation and characterization of condensation aerosols of vanadium pentoxide and pyrene.
abstract: Generation and characterization of submicron aerosols of V2O5 and pyrene, two materials with very different physicochemical properties, were studied. Vaporization-condensation methods were used to generate the aerosols. The effects of various experimental conditions on particle size and aerosol mass concentration were investigated. Also, chemical stability of the aerosols and the source materials with respect to temperature was determined. Experimental results show that there are significant differences in the nature of pyrene and V2O5 aerosols. These methods and experimental conditions can be easily adapted for generation of heterogeneous condensation aerosols of pyrene and V2O5.
