Particle collision and adhesion under the influence of near-fields

T. I. Zohdi

Vol. 2 (2007), No. 6, 1011–1018
Abstract

In many biomechanical applications, the collision of microscopic particles, under the influence of interparticle near-field forces, is an important step in an overall biophysical process. In this communication, expressions are derived relating the impact velocity needed for two small-scale particles to adhere as a function of particle sizes, material hardnesses, densities and interparticle near-field character.
