In the past decades, a variety of self-aligned functional oxides have successfully been grown on a wide range of metals using electrochemical, self-organizing anodization. The earliest reports on highly ordered oxide structures included porous aluminum oxide layers grown by optimized anodization of Al in oxalic acid. These nanoporous oxides found a considerable number of direct applications, su...

In this article, a simple and cost-effective method to create patterned nanoindentations on Al surface via mold-assisted chemical etching process is demonstrated. This report shows the reaction-diffusion method which formed nanoscale shallow etch pits by the absorption/liberation behaviors of chemical etchant in poly(dimethylsiloxane) stamp. During subsequent anodization, it was possible to obt...

Magnesium (Mg) is a promising implant material for orthopedic applications due to its biodegradability and desirable mechanical properties. However, in order for Mg to have wide-spread clinical relevance, engineering solutions that address the rapid degradation in physiological environments and promote increased bone-forming activity are necessary. The objective of this study was to develop an ...

High-aspect-ratio TiO(2) nanotube arrays formed by anodic oxidation have drawn extensive attention due to their easy fabrication and various excellent optical, electrical and biomedical properties. In contrast to conventional single-layer TiO(2) nanotubes prepared via constant-voltage anodization, we synthesize multilayer TiO(2) nanotube arrays with high surface area by using alternating-voltag...

to improve the photo-catalytic degradation of salicylic acid, we reported the fabrication of ordered tio2 nanotube arrays by a simple and effective two-step anodization method and then these tio2 nanotubes treated in a methanol solution under uv light irradiation. the tio2 nanotubes prepared in the two-step anodization process showed better photo-catalytic activity than tio2 nanotubes prepared ...

Due to increased awareness and interest in the biomedical implant field as a result of an aging population, research in the field of implantable devices has grown rapidly in the last few decades. Among the biomedical implants, metallic implant materials have been widely used to replace disordered bony tissues in orthopedic and orthodontic surgeries. The clinical success of implants is closely r...

We investigated the feasibility of hydrogen storage with electrochemically formed VO2 nanotubes. The nanotubes were fabricated through anodization vanadium metal in fluoride ion-containing organic electrolyte followed by an annealing process Ar-saturated atmosphere at 673 K for 3 h a heating rate /min. During anodization, current density significantly increased up to 7.93 mA/cm2 approximately 5...
