A simple electrochemical method is described for producing metal or semiconductor nanowires with diameters in the continuous range 10 to 200 nm. The technique involves a three-step process that begins with the electrochemical generation of an aluminum oxide template with uniform nanometer-sized pores, followed by the deposition of metal or semiconductor in them. The nanowires are then exposed for study or device fabrication by etching back the oxide matrix. Examples of cadmium nanowires fabricated by this technique are shown.

Electrochemical method is applied to prepare the porous anodic aluminum oxide (AAO) membrane. After the impregnation process, nonivamide was encapsulated into the channels of the AAO membrane. We apply the electrochemical impedance spectroscopy and polarization techniques to measure the performance of the combined material. The slight solubility of nonivamide enables it to release slowly from the AAO channels. This composite AAO-nonivamide material can show multifunctional effects, anticorrosion and antifouling, to the substrate aluminum metal.

In this paper aluminum oxide thin film was prepared by anodic oxidation in various acid baths such as sulphuric acid, chromic acid and phosphoric acid with different concentrations. The thickness and appearance of the anodized films formed has been compared. The thicknesses of anodic oxide film, coating weight per unit area and coating ratio of anodic oxide film variation were determined with respect to the different electrolyte concentrations by using the thickness determination formula. Sulphuric acid gives the highest thickness aluminum oxide films, in the operation condition of 15% H2SO4solution composition, 15V, 30±2°C, 100 mA, 60 mins.
