objective(s): titanium dioxide (tio2) nanoparticles (nps) are widely used in commercial food additives and cosmetics worldwide. uptake of these nanoparticulate into humans by different routes and may exhibit potential side effects, lags behind the rapid development of nanotechnology. thus, the present study designed to evaluate the toxic effect of mixed rutile and anatase tio2 nps on serum bioc...

the present study used a constant level of citric acid and polyvinyl alcohol and different amounts of nanocrystalline cellulose (cnc) and tio2 nanoparticles to improve the properties of starch film. the effect of different amounts of glycerol was also examined. the results of differential scanning colorimetry demonstrated that the addition of cnc increased the melting and glass transition tempe...

the corrosion protection abilities of modified copper in 2-[((z)-1-{6-[(2-sulfanylphenyl)ethanimidoyl]-2-pyridyl}ethylidene)  amino]-1-benzenthiol solution containing tio2 nanoparticles were evaluated by tafel  polarization  and  impedance  spectroscopy  in  3.5%  sodium chloride  solution.  the  samples  were  characterized  by  energy dispersive  x-ray  (edx)  and  scanning  electron  microsc...

Background & objectives: Malachite green color has been extensively used in aquaculture industry around the world. The drainage of colored wastewater containing malachite green to aquatic ecosystems has created very serious risks for human health and the environment. The purpose of this study was to investigate the removal of green malachite from aqueous solutions using photocatalysis of titani...

Yellow nail syndrome (YNS) is characterized by the triad of nail changes, lymphedema and respiratory tract involvement. Several hypotheses have been postulated to explain the findings in YNS including lymphatic drainage abnormalities along with microvasculopathy. The most recent hypothesis, proposed by Berglund and Calmark [Biol Trace Elem Res 2011;143:1-7], suggests a role of titanium dioxide ...

Selective synthesis of titanium dioxide (TiO2) polymorphs including anatase, rutile, brookite and TiO2(B) by solvothermal treatment of water-soluble titanium complexes is described with a special focus on their morphological control. The utilization of watersoluble titanium complexes as a raw material allowed us to employ various additives in the synthesis of TiO2. As a result, the selective sy...

Nanocrystals of Titanium dioxide were prepared via sol-gel and solvothermal method. They were characterized by X-ray diffraction and Scanning Electron Microscopy studies. The anatase and rutile phase reflections of the Titanium dioxide nanocrystals were identified by X-ray diffraction data. The micro strain value of the nanocrystals were analysed by W-H plot method. Very small value of micro st...

Combined reflectance, electrochemical quartz crystal microbalance, and conventional voltammetric measurements on high-area titanium dioxide electrodes in dry, electrolyte-containing solutions of acetonitrile show that electron accumulation layer formation is coupled directly to intercalation (e.g., Li+ or Na+) or to reversible adsorption (tetrabutylammonium ion) of charge compensating cations. ...
