Cobalt doped vanadium oxide exhibit good antibacterial properties due to the magnetocrystalline anisotropy because of the large surface area, small particle size, and the lower band gap energy of the material. Cobalt have been shown to induce high production of ROS, especially H2O2, and cause bacterial cell death compared to VOx and induce oxidative stress in cells and DNA damage.

In strongly correlated VO2 Oxides, competitive and coexistence phase were investigated through in situ X-Ray thermodiffraction. It was observed that insulating domains convert to correlative phase before turning to metallic due to the formation and growth of periodic rutile domains in a similar fashion at high temperature where the nucleation rather than the propagation controls the overall kinetics of phase transformation by grain boundary nucleation effect.

The presence of VO2 within the polyethylene nanofibers adds electrochemical ionic storage capacity and thermochromic optical properties, constituting an enhanced nanomaterial with characteristics of particular interest for applications in optical data storage media, thermochromic functional coatings and in lithium and magnesium batteries for mobile devices and electric vehicles.
