TLDR
In this article, mathematical expressions for the London-van der Waals (vdW) interaction energies between macroscopic objects of a few common geometrical shapes are derived subject to the assumption of additivity.Abstract:
Mathematical expressions for the London-van der Waals (vdW) interaction energies between macroscopic objects of a few common geometrical shapes are derived. The derivation is subjected to the assumption of additivity. The expressions are approximated for some limiting cases. These expressions may find uses for example in complex fluids in calculations of vdW interactions between vesicular (single wall liposomes) and liposomal (onion structures) particles or in colloidal suspensions for the calculation of vdW interaction between colloids that are coated with a stabilizing layer such as adsorbed polymers, polymer brushes or surfactants.read more

The London—van der Waals attraction between spherical particles
TL;DR: In this article, the London-v.d. interaction between two spherical particles is computed as a function of the diameters and the distance separating them, and a table is calculated which enables numerical application of the formulae derived.
