TLDR
In this article, it was shown that despite the van der Waals' forces being capable of increasing the elastic contact area between the ball and the plane, the force that is required to overcome the molecular forces arising when the contact is broken does not increase thereby.About:

Naila El Kechai,Sandrine Geiger,Arianna Fallacara,Ingrid C. Infante,Valérie Nicolas,Evelyne Ferrary,Nicolas Huang,Amélie Bochot,Florence Agnely +8 more
TL;DR: The microstructure and the phase behavior of mixtures of hyaluronic acid and liposomal gels and their impact on the vesicle mobility are evaluated and PEGylated liposomes display the highest mobility at high HA concentration both macro- and microscopically.
Dissertation
Discrete element modelling of iron ore pellets to include the effects of moisture and fines
TL;DR: Morrissey et al. as mentioned in this paper presented a mesoscopic adhesive contact model that accounts for contact plasticity and stress history dependency in the bulk solid, the Edinburgh Elasto-Plastic Adhesion (EEPA) mode, has been presented and mathematically verified.

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.
