Anodic oxide fabricated by anodizing has been widely used for nanostructural engineering, but the nanomorphology is limited to only two oxides: anodic barrier and porous oxides. Therefore, the discovery of an additional anodic oxide with a unique nanofeature would expand the applicability of anodizing. Here we demonstrate the fabrication of a third-generation anodic oxide, specifically, anodic ...

Amorphous Si nanowires have been directly synthesized by a thermal processing of Si substrates. This method involves the deposition of an anodic aluminum oxide mask on a crystalline Si (100) substrate. Fe, Au, and Pt thin films with thicknesses of ca. 30 nm deposited on the anodic aluminum oxide-Si substrates have been used as catalysts. During the thermal treatment of the samples, thin films o...

anodic aluminum oxide (aao) fabricated by two step anodization technique, is used as a template to synthesize feco nanowire arrays by ac electrodeposition technique. response surface methodology (rsm) is applied to design the experiments, fit an empirical model and optimize the conditions to achieve the best magnetic properties. the magnetic properties, pore dimensions, composition and structur...

Dye-sensitized solar cells (DSSCs) utilize high surface area metal oxide sintered particle networks to absorb molecular dyes and transport injected charge carriers. While this sintered particle architecture allows liquid electrolyte DSSCs to achieve efficiencies up to 11%, slow charge transport through the semiconductor network limits the amount of modification that can be made to the electroly...

The formation of low surface energy hybrid organic-inorganic micro-nanostructured zinc stearate electrodeposit transformed the anodic aluminum oxide (AAO) surface to superhydrophobic, having a water contact angle of 160 ̋. The corrosion current densities of the anodized and aluminum alloy surfaces are found to be 200 and 400 nA/cm2, respectively. In comparison, superhydrophobic anodic aluminum o...

Electrochemical current and potential transients were measured during anodic oxidation of aluminum, on time scales of 0.1–100 ms after anodizing began. Aluminum foil samples were prepared by surface treatments yielding oxide films of thickness 5 nm or smaller. A mathematical model was developed for the transients based on steady-state and transient conduction phenomena established for much thic...

5.1 Anodic Aluminum Oxide (AAO) Templated Nanowires Due to their small sizes and potential for controllable features, nanowires/tubes represent an attractive option for increasing the surface area of ceria-based anodes. Templated approaches are currently the most flexible routes to fabricating nanowires/tubes, as only a suitable filling method needs be developed for a particular material compos...

This paper presents the development of low cost Nano membrane fabrication system. The system is specially designed for anodic aluminum oxide membrane. This system is capable to perform the processes such as anodization and electro-polishing. The designed machine was successfully tested for ‘mild anodization’ (MA) for 48 hours and ‘hard anodization’ (HA) for 3 hours at constant 0C. The system is...

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum ox...
