Surface Forces and Their Action in Ceramic Materials
TLDR
In this paper, a descriptive account of the surface forces acting between two solids is given, with particular attention paid to the underlying mechanisms, and how they are affected by the nature of the medium between the surfaces.Abstract:
A descriptive account is given of the surface forces acting between two solids. Different contributions to the force are outlined, with particular attention paid to the underlying mechanisms, and how they are affected by the nature of the medium between the surfaces. This is followed by a discussion of the areas of ceramic science and engineering in which surface forces play a role.read more

The general theory of van der Waals forces
TL;DR: The van der Waals forces refer to the attractive forces acting between any two neutral atoms or molecules that are separated by distance large compared to their own dimensions, which decrease with distance according to a power law as mentioned in this paper.
