Phenomenological study of Au and Pt nanowires grown in porous alumina scaffolds
… has been widely used as a scaffold to synthesize nanowires and nanotubes. The porous alumina structure can be obtained from a simple electrochemical oxidation process, applying a positive voltage to an aluminum film placed in an electrolyte, and resulting in the formation of periodically arranged …
