Porous alumina templates are fabricated by anodization of Al in an acid. The characteristics of the template, such as the pore diameter, interpore separation, and the periodicity of the porous structure depend on the conditions of anodization and the acid that is used as electrolyte. The variation of pore diameter and interpore separation as a function of anodization parameters are described. T...

This study evaluated the performance of aluminum-copper alloy filtration, without the original aluminum filter, for dental radiography in terms of x-ray energy spectrum, air kerma rate and image quality. Comparisons of various thicknesses of aluminum-copper alloy in three different percentages were made with aluminum filtration. Tests were conducted on an intra-oral dental x-ray machine and wer...

This paper, studied the effect of heat treatment and anodization on corrosion resistance aluminum alloy 7075 (AA7075), with a view to improving its resistance. Microstructure micro hardness anodic film samples were aid optical metallurgical microscope automated testing machine. Linear polarization methods used assess behaviour in 0.5M HCl. The microstructure annealed sample showed formation den...

Titania nanostructured thin films have been prepared by anodization of titanium foils at different voltages in the 10–20 V range. They have been characterized by field emission scanning electron microscopy (FESEM), glancing angle X-ray diffraction (GAXRD), UV–vis diffuse reflectance and current–time transients during the anodization process. The observed nanostructure differs from that reported...

Titanium (Ti) is one of the most promising biomaterial for biomedical devices due to its high corrosion resistance and specific combination of strength and biocompatibility. Titanium dioxide (TiO2) nanostructures are obtained by electrochemical anodization of Ti foils under self-organization condition; anodization parameters such as anodization time, voltage, temperature and most important elec...

This thesis aims at the synthesis of oriented nanochannel systems for the synthesis of metallic or semiconducting nanowires. Three different synthesis strategies have been developed. First, horizontal macroto mesoporous anodic aluminum oxide (AAO) structures with individually addressable channel systems were fabricated in collaboration with the group of Dr. Anna Fontcuberta at TU München. For t...
