We present a novel method to fabricate complete and highly oriented anodic titanium oxide (ATO) nano-porous structures with uniform and parallel nanochannels. ATO nano-porous structures are fabricated by anodizing a Ti-foil in two different organic viscous electrolytes at room temperature using a two-step anodizing method. TiO2 nanotubes covered with a few nanometer thin nano-porous layer is pr...

Nanocontainers have great potentials in targeted drug delivery and nanospace-confined reactions. However, the previous synthetic approaches exhibited limited control over the morphology, size and materials of the nanocontainers, which are crucial in practical applications. Here, we present a synthetic approach to multi-segment linear-shaped nanopores with pre-designed morphologies inside anodic...

Thin films of porous anodic aluminum oxide (AAO) on tin-doped indium oxide (ITO) substrates were fabricated through evaporation of a 1,000- to 2,000-nm-thick Al, followed by anodization with different durations, electrolytes, and pore widening. A faster method to obtain AAO on ITO substrates has been developed, which with 2.5 vol.% phosphoric acid at a voltage of 195 V at 269 K. It was found th...

In this study, sodium silicate was synthesized and the characterization of zirconia which used as a suspension solution for anodization electrodeposition processes. The results synthesis using FTIR showed success making Na2SiO3 with appearance absorption from functional groups such as: silanol (Si-OH) siloxane (Si-O-Si) groups. From SEM data, it is known that each batch contains elements oxygen...

A novel ultra-smoothing process for aluminum surfaces was developed using porous alumina formation and subsequent oxide dissolution. submicron-scale periodic dimpled surface with an arithmetic mean roughness of 31.5 nm prepared by anodizing in etidronic acid solution. This specimen then anodized a sodium metaborate (NaBO 2 ) solution to form unique film extremely flat barrier layer, which diffe...

A highly self-ordered hexagonal array of cylindrical pores has been fabricated by anodizing a thin film of Al on substrate and subsequent growth of GaN and InGaN in these nanoholes has been performed. This AAO templatebased synthesis method provides a low cost process to fabricate GaN-based nanomaterials fabrication.

The mesoporous structures of tin oxide were obtained by a simple method one-stage electrochemical anodizing Sn foil in 1M NaOH various modes. Anodizing the pulse potentiostatic mode allowed determination actual value voltage drop on anode. For first time possibility obtaining films surface using galvanostatic was demonstrated. It found that morphology layers is strongly dependent mode. Based da...
