“…For the classical determination of r u , r s and G i see the work by Yue (1979). Fisenko et al (2005) investigated the effect of the dipole moment on δ G i and also considered possible explanations for sign preference. Nadykto and Yu (2004) discussed the modelling of the dipole further, and their calculations compared well with experimental nucleation measurements.…”

Abstract. Atmospheric aerosols affect climate and yet the reason for many observed events of new aerosol formation is not understood. One of the theories put forward to explain these events is that the presence of ions can enhance the formation of aerosols. The theory is called Ion Induced Nucleation and in this paper the state of observations, theory and experiments within the field will be reviewed. While evidence for Ion Induced Nucleation is accumulating the exact mechanism is still not known and more research is required to understand and quantify the effect.

The nucleation of the ionized combustion products of small (d 10 ≈ 5 μm) particles of Al, Mg, Zr, Fe, and Ti under laminar dust flame conditions at atmospheric pressure is considered in an isothermal approximation. It is shown that under conditions close to the experimental ones, the condensation of the products of gas-phase combustion of these metals is "rapid." Description of the "rapid" nucleation regime requires a nonstationary approach and knowledge of the kinetics of nucleation of the condensed phase and does not need a detailed analysis of the influence of environmental parameters on the free energy of formation of small nuclei. It is shown that the characteristic nucleation time of the gas-phase combustion products of metal particles is several orders of magnitude smaller than the residence time of the products in the combustion zone of the flame dust. This allows coagulation to be considered as the basic process which determines the degree of dispersion of primary particles of the metal combustion products.

“…They introduce a so-called enhancement factor (EF) [3,39]. If the vapor molecule has no permanent dipole, EF is generally considered as negligible, as far as clusters bear a single charge [40]. However, when evaluating EF, only the interaction between the charged cluster and the neutral particle is considered.…”

Experimental Determination of Nucleation Scaling Law for Small Charged Particles

We investigated the nucleation process at the molecular level. Controlled sticking of individual atoms onto mass selected clusters over a wide mass range has been carried out for the first time. We measured the absolute unimolecular nucleation cross sections of cationic sodium clusters Na{n}{+} in the range n=25-200 at several collision energies. The widely used hard sphere approximation clearly fails for small sizes: not only should vapor-to-liquid nucleation theories be modified, but also, through the microreversibility principle, cluster decay rate statistical models.
