The wide use of titanium dioxide nanoparticles (TiO2 NPs) in industrial applications requires the investigation of their effects on human health. In this context, we investigated the effects of nanosized and bulk titania in two different crystalline forms (anatase and rutile) in vitro. By colony forming efficiency assay, a dose-dependent reduction of the clonogenic activity of Balb/3T3 mouse fi...

Research has been carried out on the effect of adding isopropyl alcohol (IPA) formation nano titania. This study aims to determine IPA phase and particle size TiO2. In this study, titania was synthesized by hydrothermal method at a temperature 250oC with variety different additions, namely 0.2 ml, 0.4 0.6 0.8 ml. Samples were characterized using X-Ray Diffraction (XRD) Scanning Electron Microsc...

(2003) Characterization of a dye-sensitised titania solar cell electrode. Abstract: We have characterised a dye-sensitised nanoporous nanocrystalline titania film used in prototype photoelectrochemical solar cell production. From Transmission Electron Microscopy the particles were seen as mixtures of tetrahedral and rhombohedral geometries with size distribution in the range between 10 and 25 n...

The present study concerns the ecodesign of the application of an aqueous nano-TiO2 suspension on a porous limestone used in historical monuments with a spraying system through the LCA methodology, in order to define the most critical aspects of the process and to try to minimize the environmental burden during the implementation of the application process. Because of the limited knowledge curr...

Noble Gemini surfactants containing a siloxane moiety have been designed and successfully synthesized in the present study and are utilized as structure-directing agents for mesoporous metal oxides such as zirconia, titania, and vanadia. The siloxane moiety is believed to play an important nano-propping role during the surfactant removal by direct calcination, yielding thermally stable mesoporo...

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...

Transition metal oxide based disinfectants offer an effective approach for water purification. The present discovery found that silver (Ag) decorated titania (TiO(2)) nano-composites displayed high potency at 2.5 ppm within 4 h co-incubation, proved to be effective at 100% inactivation. The composite disinfectant was effective against both Gram-negative and Gram-positive bacteria, Escherichia c...
