True n-type doping of titanium oxide without formation of midgap states would expand the use of metal oxides for charge-based devices. We demonstrate that plasma-assisted fluorine insertion passivates defect states and that fluorine acts as an n-type donor in titanium oxide. This enabled us to modify the Fermi level and transport properties of titanium oxide outside the limits of O vacancy dopi...
Titanium dioxide-nickel oxide porous coatings were synthesized by Plasma Electrolytic Oxidation (PEO)/ ElectroPhoretic Deposition (EPD) in one step and within a short time. The main purpose of this research was to increase photocatalytic activity of titanium oxide by increasing surface area and coupling of titanium oxide with nickel oxide. Applied voltage effects on phase structure, surface mor...

This research demonstrates a simple method for synthesizing titanium dioxide nanoparticle-decorated carbon nanofibers. These nanofibers showed highly efficient degradation of methylene blue under UV light because of the synergistic effects of the large surface-active sites of titanium dioxide nanoparticles and the carbon nanofibers on the photocatalytic properties.
Background and Objectives: The advancement of nanotechnology has made it more important to study the destructive effects of nano-materials on organisms. Titanium dioxide and zinc oxide nanoparticles can enter the body in different ways and cause damage to the liver and other organs of the body. The purpose of this study was to evaluate the effects of zinc oxide and titanium dioxide nanoparticle...
Bioactivity of titanium depends on the quality and characteristics of its surface oxide film. Through implementation of chemical mechanical polishing (CMP) process on titanium plates, a protective oxide (titania) film grows on the titanium based implant surface. In this article, surface properties of the titanium oxide are investigated as a function of the CMP process conditions. Surface respon...
Titanium dioxide and copper oxide nanoparticles are more and more widely used because of their catalytic properties, of their light absorbing properties (titanium dioxide) or of their biocidal properties (copper oxide), increasing the risk of adverse health effects. In this frame, the responses of mouse macrophages were studied. Both proteomic and targeted analyses were performed to investigate...
biocompatibility of portland cement modified with titanium oxide and calcium chloride in a rat model
introduction: the aim of the present study was to evaluate the biocompatibility of two modified formulations of portland cement (pc) mixed with either titanium oxide or both titanium oxide and calcium chloride. methods and materials: polyethylene tubes were filled with modified pcs or angelus mta as the control; the tubes were then implanted in 28 wistar rats subcutaneously. one tube was left e...
