Abstract Biomedical applications make high demands on the development of novel bioactive materials, which are often based functionalized calcium phosphates (CaPs). In this study, pure nanoscaled hydroxyapatite (HAp) and modified HAp with titanium dioxide (TiO 2 ) both nano‐ microparticles successfully synthesized from reactants hydroxide orthophosphoric acid in a wet chemistry reaction. The obt...

Xue, School of Material and Metalurgy, Northeastern University, Shenyang, China The titanium dioxide(TiO2) was prepared by efficient decomposition of titaniumbearing blast furnace slag (TBBFS) in molten salt system. The as-prepared TiO2 were characterized by X-r...

Ultrafine titanium dioxide (TiO(2)) particles have been shown to exhibit strong cytotoxicity when exposed to UVA radiation, but are regarded as a biocompatible material in the absence of photoactivation. In contrast to this concept, the present results indicate that anatase-sized (10 and 20 nm) TiO(2) particles in the absence of photoactivation induced oxidative DNA damage, lipid peroxidation, ...

Titanium dioxide thin films were deposited on (0001) -quartz substrate by spray pyrolysis method. The method which an aerosol of Titanium Butoxide, generated ultrasonically, was sprayed on the substrate at temperature of 400 ̊C, kept at this temperature for periods of 3, 13, 19 and 39 hours. The developed films at a crystal phase correspond to the TiO2 anatase and rutile phases. Their surface r...

Background & Aims of the Study: The heterotrophic bacteria are widely used as a water microbial pollution index for drinking water. The aim of this study was to investigate the effect of metallic nanoparticles such as Zero Valent Iron (ZVI), Titanium dioxide (TiO2) and Zinc oxide (ZnO) on Heterotrophic Bacter...

in this work firstly zno nanoparticles were synthesized via a simple precipitation method. at the second step titanium dioxide and silicon dioxide shell were synthesized on the core. for preparation zno-tio2-sio2 the sol product was calcinated at 500 ºc for 2h. properties of the product were examined by x-raydiffraction pattern (xrd), scanning electron microscope (sem) and fourier transform inf...

The present study investigated the effects of exposure to metal oxide nanoparticles on vasculogenesis/angiogenesis using transgenic zebrafish. The study also examined the potential mechanisms involved in those effects using human umbilical vein endothelial cells (HUVEC). TG (nacre/fli1:EGFP) zebrafish were exposed to nano-sized titanium dioxide (TiO2), silica dioxide (SiO2), and copper oxide (C...

A new method for the growth of nanoporous thin films is described. The process is targeted to the formation of titanium dioxide (TiO2) through a low-temperature inorganic-filler chemical vapor deposition (CVD) process. The growth technique employs gas-phase reaction of an alkali metal (Na) and a metal halide (TiCl4) and subsequent thin film growth within a low-pressure coflow diffusion reactor....

Due to the unique properties and wide array of applications nanocrystalline materials based on titanium dioxide, study new synthesis approaches remains relevant. In this study, within framework extraction-pyrolytic method (EPM), we suggest using mixtures Ti- Eu-containing organic extracts valeric acid as precursors for fabrication TiO2-based powders with different Eu content: 0.5 mol%, 5 50 mol...
