The process of synthesis of vanadium pentoxide nanobands with intensive mixing of commercial V2O5 powder in aqueous solutions is investigated. However, the application of the concept of ballistic jumps to describe the growth of anisotropic structures in nonequilibrium systems under the influence of external factors (intensive mixing) is considered. In particular, it is shown how the change in temperature and change in the intensity of mixing or its absence affects the process of formation of nanostructures from vanadium oxide.

In this paper, we apply the concept of ballistic jumps to the formation of elongated nanostructures, namely the nucleation, growth and maturation of nanofibers and nanostructures of metal oxides in aqueous solutions. Using a numerical scheme to model the evolution of nanoband ensembles, the essence of which is that external influences on the system would force atoms to make jumps and change places in the crystal lattice. And the frequency of such jumps did not depend on temperature, but depended on the intensity of external action.

It was found that a characteristic feature of the process of structural transformation of particles into V2O5 nanobands is the reduction of the hydrogen pH of the solution, which can be used as an indicative integral characteristic of the rate of synthesis of vanadium pentoxide nanobands in industrial production. It should be noted that important factors that can critically affect the process of synthesis of nanostructures during intensive mixing are the composition of the suspension, its temperature, mixing speed.
