Polymer electrolytes as nanostructured materials are very attractive components for batteries and opto-electronic devices. (PEO)₈ZnCl₂ polymer electrolytes were prepared from PEO and ZnCl₂. The nanocomposites (PEO)₈ZnCl₂/TiO₂ themselves contained TiO₂ nanograins. In this work, the influence of the TiO₂ nanograins on the morphology and ionic conductivity of the nanocomposite was systematically s...

Toxicity assessment of nanoparticles, now widespread in our environment, is an important issue. We have focused attention on the carcinogenic potential of copper oxide (CuO) and titanium dioxide (TiO(2)). In experiment 1, a sequential pilot study, the effectiveness of a carcinogenic bioassay featuring intraperitoneal injection (i.p.) of 20 mg 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)...

Abstract Titanium alloys are characterised by poor tribological properties, and a ceramic TiO 2 layer formed on the surface can greatly improve its performance. By pre-depositing gold titanium surface, particles promoted outward diffusion of in conversion treatment to react with inward-coming oxygen form compact dioxide layer. The morphology, microstructure, phase constituents were SEM/EDX XRD....

OBJECTIVE The present study aimed to investigate the effect of fluoride-modified titanium surface on adhesion of irradiated osteoblasts. MATERIALS AND METHODS Fluoride-modified surface was obtained and the morphology, roughness, and chemical composition of the surface were evaluated by scanning electron microscopy, atomic force microscopy, and X-ray photoelectron spectroscopy, respectively. T...

The Haber-Bosch process has been the workhorse of ammonia synthesis for more than a century, but its environmental cost instigated search greener methods nitrogen activation. Photocatalysis using doped titanium dioxide (TiO 2 ) stands out as promising method. In this work, we explore electronic properties pristine and Ru-loaded TiO clusters activation nitrogen, hydrogen on these clusters. We st...

Abstract Rare earth metal cerium-doped titania nanoparticles (titanium dioxide [TiO 2 ]) were produced utilizing a low-cost and straightforward sol–gel technique, its enhanced photodynamic anticancer activity was tested on Y79 retinoblastoma cancer cells. The structural, optical, morphological, activity, cytotoxicity of pure TiO (Ce-doped ) investigated. In X-ray diffraction (XRD) measurements,...

Titanium dioxide photocatalysed water disinfection is induced by the interaction of light with TiO(2), which generates highly reactive free hydroxyl radicals (OH(*)). These free radicals create lethal damage that leads to bacterial death. Normally, decreasing TiO(2) particle size increases the area of light interaction. This may possibly increase the concentration of OH(*) generated and hence i...

Three-dimensional (3D) nanowire (NW) networks are promising for designing high-performance photoelectrochemical (PEC) electrodes owing to their long optical path for efficient light absorption, high-quality one-dimensional conducting channels for rapid electron-hole separation and charge transportation, as well as high surface areas for fast interfacial charge transfer and electrochemical react...

This paper remarks the general correlations of the shape and crystallinity of titanium dioxide (TiO₂) support on gold deposition and carbon monoxide (CO) oxidation. It was found that due to the larger rutile TiO₂ particles and thus the pore volume, the deposited gold particles tended to agglomerate, resulting in smaller catalyst surface area and limited gold loading, whilst anatase TiO₂ enabled...

In this study, the effects of titanium dioxide (TiO₂) nanoparticles on the sulfate attack resistance of ordinary Portland cement (OPC) and slag-blended mortars were investigated. OPC and slag-blended mortars (OPC:Slag = 50:50) were made with water to binder ratio of 0.4 and a binder to sand ratio of 1:3. TiO₂ was added as an admixture as 0%, 3%, 6%, 9% and 12% of the binder weight. Mortar speci...
