Sub-10 nm particle growth by vapor condensation – effects of vapor molecule size and particle thermal speed
Sub-10 nm particle vapor condensation vapor molecule size particle thermal speed
2010/10/21
The growth of freshly formed nanoparticles has been investigated. A new analytical expression based on a recently developed exact solution for the condensational growth rate has been derived. Based on...
The potential contribution of organic salts to new particle growth
potential contribution organic salts new particle growth
2009/5/7
Field and lab measurements suggest that low-molecular weight (MW) organic acids and bases exist in accumulation and nucleation mode particles, despite their relatively high pure-liquid vapor pressures...
Sulphuric acid closure and contribution to nucleation mode particle growth
Sulphuric acid closure nucleation mode particle growth
2009/2/8
Sulphuric acid concentrations were measured and calculated based on pseudo steady state model with corresponding measurements of CO, NOx, O3, SO2, methane and non-methane hydrocarbon (NMHC) concentrat...
An inverse modeling procedure to determine particle growth and nucleation rates from measured aerosol size distributions
inverse modeling procedure nucleation rates aerosol size distributions
2009/1/13
Classical nucleation theory is unable to explain the ubiquity of nucleation events observed in the atmosphere. This shows a need for an empirical determination of the nucleation rate. Here we present ...
Size and composition measurements of background aerosol and new particle growth in a Finnish forest during QUEST 2 using an Aerodyne Aerosol Mass Spectrometer

The study of the growth of nucleation-mode particles is important, as this prevents their loss through diffusion and allows them to reach sizes where they may become effective cloud condensation nucle...
