The Temperature Dependence of Homogeneous Nucleation Rates by the Gradient Theory
 Hrubý, Jan
We demonstrate that the incorrect temperature dependence of the nucleation rates as predicted by the classical nucleation theory is likely a consequence of the ignored dependence of the surface tension on the radius of the droplet parameterized here as a quadratic function of the pressure difference between the gas and liquid phases of the critical cluster. The size-dependent surface tension is obtained using a simplified gradient theory.

Microscopic Surface Tension in the Classical Nucleation Theory
 Němec, Tomáš ; Maršík, František
The surface tension of liquid clusters in the Classical Nucleation Theory (CNT) is investigated using the Gibbs adsorption isotherm. A theoretical derivation is given that shows the relation between macroscopic (plain-surface) surface tension and the surface tension of microscopic spherical clusters of the CNT. An exemplary water – ethanol binary condensing system is studied. It is shown that by using the microscopic surface tension in nucleation calculations an exceptional agreement between theoretical and experimental nucleation rates is achieved.
