Self-assembled Nb2O5 microcones with tailored crystallinity

  • Robert L. KarlinseyEmail author

Metal oxides have found tremendous applications in numerous fields ranging from optical [1] and electronic [2] components in the form of electrochromic devices [3] and capacitors [4] to biocompatible, bioactive coatings on orthopedic implant materials [5, 6]. Titania [7, 8, 9, 10] and alumina [11, 12, 13, 14] are among the most widely studied metal oxides, and niobium oxide, for example, is considered a valuable candidate for biomaterial applications [15] due in part to its chemical inertness [16], thermodynamic stability [5] and low cytotoxicity [17]. While metal oxides can be formed through various methodologies, anodization of metal oxides offers a convenient, efficient and relatively inexpensive method in producing metal oxides. Driven by an external power source, this process expedites normal metal oxidation, thus increasing the rate of metal oxide formation. As a result, the fast kinetics generally produce a largely amorphous oxide material. Much research has therefore been...
