In this work, 18.5 microm titanium oxide (TiO(2)) nanotube arrays were formed by the anodization of titanium (Ti) foil in ethylene glycol containing 1 wt% water and 5 wt% fluoride for 60 min at 60 V. The fast growth rate of the nanotube arrays at 308 nm min(-1) was achieved due to the excess fluoride content and the limited amount of water in ethylene glycol used for anodization. Limited water ...

In this study, the self-organized nanoporous tin oxide films were prepared on cold sprayed and foil through a voltage-controlled anodization method. The optimized spray parameters used to obtain dense structure. morphology crystallinity of samples investigated by FE-SEM XRD, respectively. Firstly, an amorphous film (SnO) with compact less regular outer layer almost uniform inner was grown durin...

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...

Mixed-phase TiO2 nanocomposite thin films consisting of anatase and rutile prepared on commercially pure Ti sheets via the electrochemical anodization and annealing treatments were investigated in terms of their photocatalytic activity for antibacterial use around dental implants. The resulting films were characterized by scanning electron microscopy (SEM), and X-ray diffraction (XRD). The topo...

PURPOSE To examine the effects of anodization (surface coating) and reduction of internal Morse taper surface area on the reversal torque values of Straumann ITI dental implants and abutments. MATERIALS AND METHODS Eighty ITI solid screw implants were mated with corresponding 5.5-mm solid abutments. The assemblies were divided into 4 test groups of 20 specimens. All abutments were torque tigh...

Clinical long-term osteointegration of titanium-based biomedical devices is the main goal for both dental and orthopedical implants. Both the surface morphology and the possible functionalization of the implant surface are important points. In the last decade, following the success of nanostructured anodic porous alumina, anodic porous titania has also attracted the interest of academic researc...

OBJECTIVE To determine the effect of surface anodization on the interfacial strength between an orthodontic microimplant (MI) and the rabbit tibial bone, particularly in the initial phase after placement. METHODS A total of 36 MIs were driven into the tibias of 3 mature rabbits by using the self-drilling method and then removed after 6 weeks. Half the MIs were as-machined (n = 18; machined gr...

Thin film solar cells are currently being investigated as an affordable alternative energy source because of the reduced material cost. However, these devices suffer from low efficiencies, compared to silicon wafer solar cells, due to the poor absorption of longer wavelengths of light in the very thin active layer. One method of improving the efficiency of thin film solar cells is to use light ...

Steel was anodized in 10 M NaOH to enhance its surface texture and internal surface area for application as an electrode in supercapacitors. A mechanism was proposed for the anodization process. Field-emission gun scanning electron microscopy (FEGSEM) studies of anodized steel revealed that it contains a highly porous sponge like structure ideal for supercapacitor electrodes. X-ray photoelectro...

In this study, we used the electrochemical anodization to prepare TiO2 nanotube arrays and applied them on the photoelectrode of dye-sensitized solar cells. In the field emission scanning electron microscopy analysis, the lengths of TiO2 nanotube arrays prepared by electrochemical anodization can be obtained with approximately 10 to 30 μm. After titanium tetrachloride (TiCl4) treatment, the wal...
