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:

How does a tip tap
Nancy A. Burnham,O. Behrend,F. Oulevey,Gérard Gremaud,Pascal Gallo,Delphine Gourdon,E. Dupas,Andrzej J. Kulik,Hubert M. Pollock,G. A. D. Briggs +9 more
TL;DR: In this article, a model and numerical simulations are presented for the response of an atomic force microscope cantilever to the extremely nonlinear impacts received while tapping a sample. But the dependence of the cantilevers amplitude and phase upon the sample stiffness, adhesion and damping are investigated using these simulations, and it is found that topographic" tapping images are not independent of sample properties, nor will it be trivial to measure materials' properties from the tapping data.

Energetics and dynamics of SNAREpin folding across lipid bilayers
Feng Li,Frederic Pincet,Eric Perez,William S. Eng,Thomas J. Melia,James E. Rothman,David Tareste +6 more
TL;DR: The interaction energy–versus–distance profiles of assembling SNAREpins reveal that SNARE motifs begin to interact when the membranes are 8 nm apart, and even after very close approach of the bilayers, theSNAREpins remain partly unstructured in their membrane-proximal region.

Dust coagulation and fragmentation in molecular clouds. I. How collisions between dust aggregates alter the dust size distribution
Chris W. Ormel,Chris W. Ormel,D. Paszun,Carsten Dominik,Alexander G. G. M. Tielens,Alexander G. G. M. Tielens +5 more
TL;DR: In this article, the authors investigated the collisional evolution of the dust population by combining two models: a binary model that simulates the collision between two aggregates and a coagulation model that computes the dust size distribution with time.

Measuring surface forces in aqueous electrolyte solution with the atomic force microscope
TL;DR: In this paper, it has been realized that the atomic force microscope, which is normally used to image the topography of surfaces with high resolution, can also be used to measure surface forces.

TL;DR: In this article, approximate theoretical formulae are developed to predict the magnitude and onset of capillary adhesion between a smooth adhering particle and a surface with roughness on the nanometer scale.

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.

LXXIX. The cohesive force between solid surfaces and the surface energy of solids
TL;DR: In this paper, an expression for the cohesive force between two unequal spheres in geometrical contact is derived and the surface energy of the solid may be computed from the constant in this expression.
