A new synthesis pathway for colloidal silica spheres coated with crystalline titanium oxide and its comparative cyto- and genotoxic study with titanium oxide nanoparticles in rat osteosarcoma (UMR106) cells
(Elsevier Science, 2013-03)
Spherical particles with an amorphous core of silica and a crystalline shell of titanium oxide (SiO2@TiO2) formed in a three-step procedure, being the last step a mild chemical treatment. SiO2@TiO2 had a shell with pores ...
Evaluation of annealed titanium oxide nanotubes on titanium: From surface characterization to in vivo assays
(Wiley-liss, div John Wiley & Sons Inc., 2020-10)
The entire route from anodic oxidation and surface characterization, including in vitro experiments and finally in vivo osseointegration assays were performed with the aim to evaluate nanotubular and crystalline annealed ...
Diamond, titanium dioxide, titanium silicon oxide, and barium strontium titanium oxide nanoparticles as matrixes for direct matrix-assisted laser desorption/ionization mass spectrometry analysis of carbohydrates in plant tissues
(American Chemical Society, 2010-07)
Nanoparticles (NPs) of diamond, titanium dioxide, titanium silicon oxide, barium strontium titanium oxide, and silver (Ag) were examined for their potential as MALDI matrixes for direct laser desorption/ionization of ...
Effect of titanium-doping on the properties of vanadium antimonate catalysts
(Elsevier Science, 2000-02)
Catalysts of nominal compositions VSb1 - xTixO4, with x = 0, 0.1, 0.2 and 0.4, were prepared by solid state reaction of vanadium(V) oxide, antimony(III) oxide and titanium(IV) oxide mixtures. Their structural and catalytic ...
Bioactivity enhancement of cerium-containing titanium oxide nanotubes. Relationship between surface reactivity and nanostructuring process
(Elsevier Science SA, 2019-09)
The present study is focused on the development of a novel surface by electrochemical modification of titanium substrates (Ti) to enha nce bone -bonding ability. A Ce -containing conversion coating was formed on Titanium ...
Neurotoxicity mediated by oxidative stress caused by titanium dioxide nanoparticles in human neuroblastoma (SH-SY5Y) cells
(Elsevier Gmbh, 2020-01)
Background: Titanium is widely used in biomedicine. Due to biotribocorrosion, titanium dioxide (TiO2) nanoparticles (NPs) can be released from the titanium implant surface, enter the systemic circulation, and migrate to ...
Thickness determination of anodic titanium oxide films by electron probe microanalysis
(Elsevier Science Inc, 2017-08)
Thin film thickness can be readily associated to the X-ray intensities emitted under electron bombardment. The aim of this work is to develop a method for measuring titanium oxide thicknesses in biomaterials from the X-ray ...
The Box-Benkhen experimental design for the optimization of the electrocatalytic treatment of wastewaters with high concentrations of phenol and organic matter.
(IWA PUBLISHING, 2009-01-01)
In this work, the Box-Benkhen experimental Design (BBD) was applied for the optimization of the parameters of the electrocatalytic degradation of wastewaters resulting from a phenolic resins industry placed in the suburbs ...
Smooth semicompact multilayer coating of TiO2 obtained by combining anodic oxidation and sol-gel techniques
(Elsevier, 2022-12-15)
Titanium oxide provides biological and hemocompatible properties to different biomedical devices made of titanium or its alloys. However, since this oxide naturally has a very low thickness and low tribological performance, ...
