Highly Ordered Anodic Alumina Nanofibers Fabricated via Two Distinct Anodizing Processes

Ultra-High Density Single Nanometer-Scale Anodic Alumina Nanofibers Fabricated by Pyrophosphoric Acid Anodizing

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 ...

Highly ordered anodic porous alumina membrane and its surface modification approaches for biomedical application

During recent years, the anodization of aluminum, due to its great commercial significance, represents one of the most important and widespread method used for the synthesis of ordered nanostructures. Whose geometry is controlled by diverse synthesis factors which include the voltage applied, the temperature of the electrochemical environment in which the synthesis is carried out, the reagent u...

Highly ordered diamond and hybrid triangle-diamond patterns in porous anodic alumina thin films

Ordered three-dimensional interconnected nanoarchitectures in anodic porous alumina

Three-dimensional (3D) nanostructures combine properties of nanoscale materials with the advantages of being macro-sized pieces when the time comes to manipulate, measure their properties or make a device. However, the amount of compounds with the ability to self-organize in ordered 3D nanostructures is limited. Therefore, template-based fabrication strategies become the key approach towards 3D...

Highly ordered porous alumina with tailor-made pore structures fabricated by pulse anodization.

A new anodization method for the preparation of nanoporous anodic aluminum oxide (AAO) with pattern-addressed pore structure was developed. The approach is based on pulse anodization of aluminum employing a series of potential waves that consist of two or more different pulses with designated periods and amplitudes, and provides unique tailoring capability of the internal pore structure of anod...
