The physical and biological properties of TiO2 materials including NanoTiO2, micrometerTiO2 and NanoTiO2 tubes have been studied using scanning electron and infrared spectrometer, X-ray diffraction instrument as well as 3-(4,5dimethylthiazol 2-yl)-2,5 diphenyltetrazo-lium bromide (MTT) colorimetric method, respectively. These materials are prepared by chemical deposition and anode oxidation met...

Advanced oxidation processes (AOPs) are considered highly competitive water treatment technologies for the removal of organic pollutants. Among AOP techniques, photocatalysis has recently been the most widely studied. Our aims were to investigate how the dispersion of nanosized titanium dioxide (nanoTiO2) applied in photodegradation-based procedures can be stabilized with cyclodextrins in order...

Here we characterize the toxicity of environmentally-relevant forms of engineered nanomaterials (ENMs), which can transform during wastewater treatment and persist in aqueous effluents and biosolids. In an aerosol exposure scenario, cytotoxicity and genotoxicity of effluents and biosolids from lab-scale sequencing batch reactors (SBRs) to A549 human lung epithelial cells were examined. The SBRs...

This study aimed to investigate the influence of bimodal TiO2/nanoTiO2 coatings obtained in PVD/ALD hybrid process on an Al-Si-Cu-type aluminium alloy physicochemical properties investigated materials. The reference materials were uncoated substrates and samples coated with TiO2 single PVD ALD processes. Tests carried out morphology using scanning electron microscopy (SEM) atomic force (AFM) de...

Despite uses of titanium dioxide (TiO2) particles in various consumer and medical products therapy increasing human daily exposure, little studies were conducted on its cardiotoxicity. Thus, this study was designed to investigate the possible modulation of nanoTiO2 induced genotoxicity, mutagenicity and apoptosis by chlorophyllin (CHL) coadministration in mice cardiac cells. Mice were injected ...

NanoTiO2 , nanoZrO2 and TiO2 /ZrO2 nanocomposite were prepared via sol gel method by using ultrasonic irradiation. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4 and titanium tetra 2-propoxide was diluted by 2-propanol and deionized water The TiO2 /ZrO2 nanocomposite was synthesized from directly mixing Titanium dried gel into Zirconium gel. The reaction mixture w...

background: metal nanoparticles have been recently applied in dentistry because of their antibacterial properties. this study aimed to evaluate antibacterial effects of colloidal solutions containing zinc oxide (zno), copper oxide (cuo), titanium dioxide (tio2) and silver (ag) nanoparticles on streptococcus mutans and streptococcus sangius and compare the results with those of chlorhexidine and...

Cement is as an adhesive that binds pieces of solids together. In this research, the main materials used in construction such cement, concrete and steel are described. After described to what extent nanomaterials silicon, titanium nanoxide, polypropylene nanofibers, microsilica nano calcium carbonate do compressive strength cement increase prevent corrosion erosion. Polypropylene nano-fibers ad...
