The nanotubes were prepared by anodizing method. anodization process was carried out using 60 volts between two titanium plates as electrodes, leaving a distance the electrodes 6.5 cm. electrolyte contains (0.5 w/w NH4F, 2 H2O, 5 ethylene glycol). A scanning electron microscope (SEM) used to examine surface morphology of dioxide (TiO2). SEM image shows that tubes are in range (80-90 nm) diamete...

Anodic formation of titania nanowires has been interpreted using a bamboo-splitting model; however, a number of phenomena are difficult to explain with this model. Herein, transition from nanotubes to nanowires is investigated by varying the anodizing conditions. The results indicate that the transition requires a large number of hydrogen ions to reduce the passivated area of tube walls, and th...

Titanium dioxide is a very attractive material in catalysis. Although the titanium exhibits superior proper-ties ultra violet radiation, activity of catalyst can be improved by some modifications specially for daylight radiation. was colored thermal decomposition sodium borohydride at 400 0C. The gray nanotube-titanium obtained where molar ratio to borohydride, 1.2 and 0.6. black prepared makin...

TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulate...

A thermal interface material (TIM) is a crucial material for transferring heat from a die to a heatsink. We developed a new TIM composed of carbon nanotubes, silicon thermal grease, and chloroform. The thermal impedance of the TIM was measured using a new device based on thermometer principles to measure thermal impedance and resistance. This device consists of an alumina substrate, titanium tu...

Presented paper deals with images of nanotubes that provide a new way of a surface bioactivation of dental titanium implants. The evaluation of selected material parameters forms an important part of material quality assessment. The first step is an image segmentation and object detection. In the following step, object classification is a crucial point in separation object. Various methods coul...

Peroxo-titanium decorated H-titanate-nanotube-based hierarchical microspheres (PTHM) with a large surface area (368 m(2) g(-1)) and mesoporous structure were prepared by an alkaline hydrothermal method in the presence of H2O2 followed by acid wash, and they exhibited improved activity in degradation of Rhodamine B under visible light irradiation.

In this study, the highly-ordered TiO(2) nanotube (TNT) arrays on titanium sheets were prepared by an anodic oxidation method. Under UV illumination, the TNT films demonstrated the higher photocatalytic activity in terms of 2,3-dichlorophenol (2,3-DCP) degradation in aqueous solution than the conventional TiO(2) thin films prepared by a sol-gel method. The effects of dissolved oxygen (DO) and p...
