Chemical Physics of Nanomaterials


The method of stochastic simulations was applied to studying the kinetics of nucleation and growth of nanoparticles from solution in the presence of a ligand-yielding stabilizer. It was established that, at large stabilizer concentrations the process is not described within the framework of the law of mass action, being appreciably dependent on stochastic fluctuations in the number of free vacancies at the surface of the growing particle. This factor is responsible for the limitation of particle growth and for the formation of stable particles with a loose packing and dendrite-like structure. With decreasing stabilizer concentration, the kinetic characteristics of the process approach those typical of classical kinetics, whereas the packing density increases.
