Mixed-phase TiO2 nanocomposite thin films consisting of anatase and rutile prepared on commercially pure Ti sheets via the electrochemical anodization and annealing treatments were investigated in terms of their photocatalytic activity for antibacterial use around dental implants. The resulting films were characterized by scanning electron microscopy (SEM), and X-ray diffraction (XRD). The topo...

Nanocomposite TiO2 coatings of mixed anatase–rutile crystalline polymorphs with strong adherence to glass substrates were prepared via spray-plasma deposition method. The rutile content was varied between 0 and 30 mol%. coating showed an enhanced photocatalytic activity towards cefixime antibiotic decomposition in aqueous solutions under UVA (λ = 365 nm) light illumination. significantly increa...

In this study, the authors report the production of nanocomposite-enhanced phase-change materials (NEPCMs) using the direct-synthesis method by mixing paraffin with alumina (Al2O3), titania (TiO2), silica (SiO2), and zinc oxide (ZnO) as the experimental samples. Al2O3, TiO2, SiO2, and ZnO were dispersed into three concentrations of 1.0, 2.0, and 3.0 wt.%. Through heat conduction and differentia...

Titania (TiO2) induced photocatalysis has been widely investigated and applied as a disinfection strategy in many industrial and clinical applications. Reactive oxygen species (ROS), including hydroxyl radicals (•OH), superoxide radicals ( − •2 O ) and hydrogen peroxide (H2O2), generated in the photocatalytic reaction process are considered to be the active components prompting the bactericidal...

A novel silica-titania (SiO2-TiO2) nanocomposite has been developed to effectively capture elemental mercury (Hg0) under UV irradiation. Moisture has been reported to have an important impact on this nanocomposite's performance. In this work, the role of moisture on Hg0 removal and reemission as well as the corresponding mechanisms was investigated. Hg0 removal experiments were carried out in a...

density functional theory calculations were performed to investigate the interactions of nh3 molecules with tio2/mos2 nanocomposites in order to completely exploit the adsorption properties of these nanocomposites. given the need to further comprehend the behavior of the nh3 molecules oriented between the tio2 nanoparticle and mos2 monolayer, we have geometrically optimized the complex systems ...

Polyaniline nanocomposite using metal oxides have wide variety of applicability because its enhanced properties to that pure polyaniline. Here we employed titanium dioxide as the oxide synthesize polyaniline composite (PANi-TiO2 ) through chemical oxidative polymerization in-situ. The obtained PANi-TiO2 is tested for powder X-Ray diffractometry (XRD), & Scanning electron microscopy(SEM).

Interface issues are common and crucial in nanocomposites or nanohybrid systems since the interface area is enormous on the nanoscale. In the 0-3 polymer nanocomposites, in which nano-inclusions (0-dimension) are embedded in 3-dimensionally connected polymer matrix, enhanced dielectric permittivity could be induced by the interfacial polarization at the interfaces between the nano-inclusions an...

We studied the effect of titanium dioxide (TiO2)nanoparticles (NPs)on ion conductivity Na+ ion-conducting nanocomposite solid polymer electrolyte (NCSPE) composed polymers poly(ethylene oxide) (PEO) and polyvinyl pyrrolidone (PVP), sodium metaperiodate (NaIO4)at concentration 10 wt%, with added TiO2NPs average size ∼ nm at from 1 wt% to 5 wt%.
