Nanoimprinting Using Highly Ordered Anodic Porous Alumina with Reduced Hole Periods

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

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...

Fabrication of a porous anodic alumina membrane

With the aim of developing a process for surface enlargement on an electrode for measuring brain activity attempts have been made to fabricate a porous anodic alumina membrane directly on the electrode. The porous membrane was intended to be used as scaffold for deposition of an electrically conducting polymer on the electrode surface. A silicon wafer with gold electrodes was the base onto whic...

Fabrication of Highly Ordered Gold Nanorods Film Using Alumina Nanopores

A simple method for fabrication of highly ordered gold nanorod film is introduced in this article. The procedure is based on thermal evaporation of gold into a porous anodic alumina film (PAA). The PPA film was fabricated by combining the hard and mild anodization. This combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with c...
