Random sequential adsorption

Random Sequential Adsorption (RSA) is a theoretical model used to describe the process of particle deposition onto a surface. In this model, particles are randomly placed on a surface one at a time. Each particle is allowed to "adsorb" or stick to the surface only if it does not overlap with any already adsorbed particles. Once a particle is successfully adsorbed, it stays on the surface, and subsequent particles are added under the same condition of non-overlapping.
