Variability of nanosystems

Abstract

On a surface of growing nanoparticles a mechanism of synchronization of molecular fluctuations operates increasing their scale up to macroscopic one. Thereof the kinetic equation for states distribution function of nanoparticles approaches the Fokker–Planck equation that is experimentally established on an example of nanoparticles of different nature. In a series of suspensions and aerosols, where the ordered aggregates of nanoparticles are formed, aggregation is multi–stage process, and at each stage the change of a size distribution function of aggregates is also described by the Fokker–Planck equation. Multi–stage aggregation is completed by appearance of the particles in system with multilevel hierarchical texture having tendency to accept polyhedral shape. Aforementioned features of nanosystems can be treated as development of variability and ability of systems to self–organization.
