We studied flow rate, electrolytes effects, titanium dioxide separation and reuse and sunlight application on photocatalysis in a tubular photoreactor integrated with the titanium dioxide separation/reuse. The circulative flow treatment was preferred over the single pass treatment. Phenol and TOC removals in tap and deionized waters were a maximum at the circulative flow rate of 600 ml min and ...

The morphology of titanium dioxide and titanium dioxide-tungsten trioxide nanocomposite films fabricated by anodizing in a glycerol solution containing 0.13 M NH4F and different quantity of Na2WO4 was investigated as a function of sodium tungstate concentrations. The effects of sodium tungstate concentration on the surface morphology were observed by scanning electron microscopy (SEM). It was c...

Tailoring the nano-morphology and nano-architecture of titanium dioxide (TiO₂) is the most important task in the third generation solar cells (Dye sensitized solar cells/Quantum dot sensitized solar cells) (DSSCs/QDSSCs). In this article we present complete study of surfactant free synthesis of TiO₂ nanostructures by a simple and promising hydrothermal route. The plethora of nanostructures like...

In this study, TiO2 nanoparticles have been synthesized by sol-gel method. Then, the effects of the different pHs, stirring times, surfactants (CTAB and Span 20) and temperatures on TiO2 nanoparticles were studied. The X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), and transmission electron microscopy (TEM) analyses were used to characterize the samples. The obs...

A large quantity of white gas containing titanium dioxide and hydrogen chloride was generated unexpectedly during an experiment in a chemical laboratory. Fourteen students and staff complained of nausea, dyspnea, or respiratory irritation immediately after inhaling the gas. On arrival at Saint Luke's International Hospital, more than half of the patients presented with low-grade fever. Symptoms...

In this research, the thin films of N-S doped titanium dioxide (TiO2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. Furthermore, titanium dioxide (TiO2) was functionalized with thiourea. Furthermore, N-S doped titanium dioxides (NSTO) were fixed on glass balls by glass balls fixed-bed reactor system. Besides, the effect of ...

AIM The aim of the study was to comparatively analyze the in vitro cell adhesion between nano coated titanium dioxide, and calcium hydroxyapatite (HA) coated titanium samples. MATERIALS AND METHODS Nano coated titanium dioxide, and calcium HA were coated onto the titanium samples by drop casting with NAFION membrane and cell culture was done by seeding human osteoblastic sarcoma cells on the ...

Engineered nanoparticles (ENPs), products from modern nanotechnologies, can potentially impact the marine environment to pose serious threats to marine ecosystems. However, the cellular responses of marine phytoplankton to ENPs are still not well established. Here, we investigate four different diatom species (Odontella mobiliensis, Skeletonema grethae, Phaeodactylum tricornutum, Thalassiosira ...
