Heterogeneous nucleation of molecular and dipolar fluids

We present a summary of the main properties of an interaction site model for heterogeneous nucleation of molecular and dipolar fluids on charged hard spheres. Density functional theory is used to calculate the work of formation of critical nuclei formed on small spherical particles. Nucleation rates depend on the size and charge of the central seed. Sign preferences lead to rates of nucleation that differ by several orders of magnitude.
