Some comment relating to the efficiency of nanoparticles differentiation in the field of centrifugal forces

The dependences of the parameters of the centrifugal field (speed, radius of the centrifuge rotor) and the separation efficiency of nanostructured objects by size (partition coefficient) were considered. The analysis based on the probability distribution of the different energy states of particles with the sizes ranging from units to tens nanometers in the field of centrifugal forces on the basis of Boltzmann distribution was carried out. The integral of the force of resistance to movement of the particles in a centrifuge rotor comprising Stokes force, was calculated from the experimental data of nanoparticles separation in the centrifugal force field, produced for silica nanoparticles.
