The surface properties of TiO2-PVDF nanocomposite membranes were investigated by incorporating different chemically modified TiO2 nanoparticles into the poly (vinylidene fluoride) (PVDF) matrix. The nanocomposite membranes were prepared via dual coagulation bath diffusion and the induced phase inversion method. The membrane surface morphologies were investigated by using SEM and AFM and related...

Plasmonic photocatalytic nanocomposites of TiO2 and Au nanoparticles (NPs) have recently attracted the attention researchers, who aim to improve activity potential NPs. In this study, we report enhancement for a Au/TiO2 nanocomposite prepared by plasma–liquid interaction method using an atmospheric microplasma apparatus. The enhanced is demonstrated degradation methylene blue (MB) in water unde...

The results of this study indicate that titanium dioxide nanoparticles (nano-TiO2) possess adsorptive, photocatalytic, bactericidal, virucidal and fungicidal properties, which are used in antibacterial coating, for air water disinfection. In parallel with studies the physicochemical characteristics dioxide, its toxicological assessment was carried out to prevent possible harmful effects on huma...

Background: The development of dental caries around orthodontic brackets is a common complication treatment. Objectives: This study aimed to compare the antibacterial efficacy stainless steel (SS) coated with copper oxide nanoparticles (CuO-NPs), titanium dioxide (TiO2-NPs), and hydroxyapatite silver (HA-SNPs) against Streptococcus mutans. Methods: In this in vitro, experimental study, 20 were ...

Fume hoods are one of the most common types of equipment applied to reduce the potential of particle exposure in laboratory environments. A number of previous studies have shown particle release during work with nanomaterials under fume hoods. Here, we assessed laboratory workers' inhalation exposure during synthesis and handling of CuO, TiO2 and ZnO in a fume hood. In addition, we tested the c...

Herein, a ternary nanocomposite with TiO2 nanoparticles anchored on reduced graphene oxide (rGO)-encapsulated Fe3O4 spheres (Fe3O4@rGO@TiO2) is presented as a high efficient heterogeneous catalyst for photo-Fenton degradation of recalcitrant pollutants under neutral pH. Fe3O4@rGO@TiO2 was synthesized by depositing TiO2 nanoparticles on the surface of the Fe3O4 spheres wrapped by graphene oxide ...

Abstract The current work aims to improve the metal oxide characteristics for mosquito control. Un-doped and Y-doped CuO have been synthesized by simple chemical route. Structural, composition, morphological properties were characterized XRD, Raman spectra, EDX, SEM, TEM techniques. obtained results revealed that was strongly affected Y 3+ support, in which crystallite size decreased, surface a...

We fabricated titanium dioxide (TiO2)-silica (SiO2) nanocomposite structures with controlled morphology by a simple synthetic approach using cooperative sol-gel chemistry and block copolymer (BCP) self-assembly. Mixed TiO2-SiO2 sol-gel precursors were blended with amphiphilic poly(styrene-block-ethylene oxide) (PS-b-PEO) BCPs where the precursors were selectively incorporated into the hydrophil...

A novel electrochemical sensor poly(taurine)/TiO2-graphene nanocomposite modified glassy carbon electrode (PT/TiO2-Gr/GCE) was fabricated. This sensor was based on an electrochemically polymerized taurine layer on a TiO2-graphene modified glassy carbon electrode. The electrochemical behavior of acetaminophen and caffeine at the modified electrode was studied by cyclic voltammetry and differenti...
