Abstract

The main target of this project is to give continuity to the research activities already started here in UFABC. It is important to emphasize that the development of the previous project has been very fruitful with a strong impact not only to understand of microtube and hierarchical structure formation, but also with potential technological applications. Therefore, we intend to extend this research line evolving hollow microstructure decorated with nanostructures. Along this line, the objective of this proposal is to synthesize hierarchical structure and study the physical properties of two families of transition metal oxides: zinc oxide ZnO and TiO2. Within this context, a better understanding on the formation kinetic of microtubes, nanostructures, and hierarchical structures through thermal oxidation method along with the simultaneous passage of electric current should reveal important results. Furthermore, morphological, structural, electric, and magnetic properties of the samples will be studied. (AU)
