Nanoscience and nanotechnology became a distinguishable and multidisciplinary field of research with emerging applications. In the field of metal oxides, the discovery of superconductive oxides, and oxides with large magnetoresistance has raised great attention, especially to those from transition metals. Metal oxides benefit from the large electronegativity of the oxygen to induce strong electron connections with the nearby atoms, which affects the chemical properties and surface energy of the materials. Chemical synthesis of metal oxides nanoparticles allows a good control of the structure...
