Abstract
The influence of the physical properties of nanoparticle materials and the parameters of the molecule-particle-interaction potential on the diffusion of nanoparticles has been studied on the basis of kinetic theory. It has been established that unlike Brownian particles, the diffusion of fairly small nanoparticles is substantially dependent on their material. This effect becomes stronger with growth in the carrier-gas temperature. In all cases the use of the well-known Cunningham-Milliken-Davies correlation brings about considerable errors in determining the diffusion coefficient of nanoparticles.
