The electropolishing behaviour of 73 brass was studied by means of a rotating cylinder electrode (RCE) in a 70 vol % H3PO4 solution at 27 ◦C. Owing to the formation of a blue Cu2+-rich layer on the brass-RCE, an obvious transition peak was detected from kineticto diffusion-controlled dissolution in the anodic polarisation curve. Electropolishing was conducted at the potentials located at the tr...

In the current research project, sol-gel electrophoresis technique was utilized to grow titanium dioxide (TiO2) nanotubes. A titanium sol was prepared using organometallic precursors of titanium to fill the template channels. The prepared solwas driven into nanopores of porous anodic aluminum oxide templates under the influence of a DC electric field to form nanotubes on the pore walls. Tube fo...

Porous GaAs layers have been produced by electrochemical anodic etching of (100) heavily doped p-type GaAs substrate in HF solution. Scanning electron microscopy revealed the presence of etch pits ranging in size from 0.01 to 2 mm and they were strongly dependent on the electrochemical etching conditions. The etch pits chemical composition consists of O, Ga and As whereas the porous structure c...

This thesis is devoted to the study of vertical Pourous Anodic Alumina templates (PAA) and the application thereof for nanoorganization and device fabrication. Our principle objective was to develop an anodization method of Al that allows a reproducible fabrication of PAA offering the possibility to create complex porous nanostructures as well as the organization of nanomaterials. The PAA fabri...

The PAN-based carbon fibers were modified using anodic oxidation method with different electrolyte such as sulfuric acid, sodium sulfate and sodium hydroxide for improving its surface properties and its composites interphase properties. It is well know that different electrolyte have different oxidizability and electrochemical characterization. The influence of different electrolytes on the eff...
