The use of metallic nanowires is mostly reduced to scientific areas where a small quantity nanostructures are needed. In order broaden the applicability these nanomaterials, it necessary establish novel synthesis protocols that provide larger amount than conventional laboratory fabrication processes at more competitive cost. this work, we propose several modifications electrochemical in increas...

Solid state nanoporous membranes show great potential as support structures for biointerfaces. In this paper, we present a technique for fabricating nanoporous alumina membranes under constant-flow conditions in a microfluidic environment. This approach allows the direct integration of the fabrication process into a microfluidic setup for performing biological experiments without the need to tr...

A detailed study of the pore-widening rate of nanoporous anodic alumina layers as a function of the anodization voltage was carried out. The study focuses on samples produced under the same electrolyte and concentration but different anodization voltages within the self-ordering regime. By means of ellipsometry-based optical characterization, it is shown that in the pore-widening process, the p...

Abstract This study introduced an electrochemical process for the formation of a biofunctional oxide layer on almost equiatomic NiTi alloy surface. The core technology used in proposed was anodization HNO3 electrolyte under pulsed voltage, which allowed poreless Ni-free TiO2 with thickness ~50 nm that exhibited hydrophilicity and corrosion protection. acquired led to enhanced endothelial cell a...

The radiopacity of esthetic restorative materials has been established as an important requirement, improving the radiographic diagnosis. The aim of this study was to evaluate the radiopacity of six restorative materials using a direct digital image system, comparing them to the dental tissues (enamel-dentin), expressed as equivalent thickness of aluminum (millimeters of aluminum). Five specime...

Nanoporous anodic aluminum oxide (AAO) has been used in many different fields of science and technology, due to its great structural characteristics. Solar selective surface is an important application of this type porous material. This paper investigates the effect of nanoporous AAO properties, including; film thickness, pore area percentage and pore diameter, on absorption spectra in the rang...

Anodization techniques by alternating current (ac) are introduced in this review. By using ac anodization, laminated alumina films are fabricated. Different types of alumina films consisting of 50-200 nm layers were obtained by varying both the ac power supply and the electrolyte. The total film thickness increased with an increase in the total charge transferred. The thickness of the individua...
