We report straight pores in titanium dioxide produced by a pattern transfer method with titanium fluoride hydrolysis. The resulting films on fluorine-doped tin oxide had pores with diameters of 30 nm and depths of 500 nm, corresponding to aspect ratios of 1:17.

BACKGROUND The aim of the present study is a comparative evaluation of inflammatory infiltrate, microvessel density, vascular endothelial growth factor, nitric oxide synthase, and proliferative activity in soft tissues below intraorally welded titanium bars. METHODS Twenty-two patients participated in this study. All patients carried immediately loaded one-stage titanium implants splinted wit...

Titanium alloys have been extensively used as promising implant materials. The anodic oxide layer on the surface of this alloy can be a compact, porous or a tubular structure, which has a direct impact on the final characteristics of the implants. In this study, nano topographic oxide arrays were synthesized on the surface of titanium substrates using an anodic oxidation technique. The anodizat...

Titanium and its alloys have good biocompatibility with body cells and tissues and are widely used for implant applications. However, clinical procedures place more stringent and tough requirements on the titanium surface necessitating artificial surface treatments. Among the many methods of titanium surface modification, electrochemical techniques are simple and cheap. Anodic oxidation is the ...

Changes in hydrogen distribution in -phase titanium hydrides (TiH1:92 1:95), covered with titanium oxide layers (TiO and TiO2), were investigated by elastic recoil detection analysis (ERDA) after isochronal and isothermal annealing experiments. The hydrogen concentration near to the surface of the hydride exponentially decreased as a function of annealing time in the temperature range from 423 ...

This paper presents a design of solar tracking system driven by 12V or 24V DC motor controlled by a microchip ‘Intelligent Drive unit IBL2403’[1]. The proposed double axis rotation solar tracker ensures the optimization of conversion of solar energy to electrical energy by orientation of ‘titanium-oxide’ PV panels’ [2-6] in accordance to the hemispherical position of the Sun. The hemispheroidal...

This research investigated the direct bonding mechanism of dissimilar materials such as metals and plastic by the conventional hot pressing process. The press area of 4 x 4 mm2 was used for direct bonding. The results of the study showed that titanium was completely bonded to polyamide 66. On the other hand, titanium was not bonded to polystyrene. In the case of bonding material of titanium wit...

As a white pigment, titanium oxide is used for cosmetic application. This oxide is well known to have the photo catalytic activity. Therefore a certain degree of sebum is decomposed by the ultraviolet radiation in sunlight. In this work, titanium phosphates were prepared with additives (urea, sodium lactate, and glycerin) as a novel white pigment. Their chemical composition, powder properties, ...
