the corrosion protection abilities of modified copper in 2-[((z)-1-{6-[(2-sulfanylphenyl)ethanimidoyl]-2-pyridyl}ethylidene)  amino]-1-benzenthiol solution containing tio2 nanoparticles were evaluated by tafel  polarization  and  impedance  spectroscopy  in  3.5%  sodium chloride  solution.  the  samples  were  characterized  by  energy dispersive  x-ray  (edx)  and  scanning  electron  microsc...

This research demonstrates a simple method for synthesizing titanium dioxide nanoparticle-decorated carbon nanofibers. These nanofibers showed highly efficient degradation of methylene blue under UV light because of the synergistic effects of the large surface-active sites of titanium dioxide nanoparticles and the carbon nanofibers on the photocatalytic properties.

Nowadays green synthesis of metal nanoparticles is a developing area of research. In this study, titanium dioxide nanoparticles were biosynthesized using an aqueous solution of Echinacea purpurea herba extract as a bioreductant. This is novel and interesting method for synthesis of TiO2 nanoparticles. The prepared titanium dioxide nanoparticles were characterized using ultraviolet–visible spect...

The present work was targeted to design a surface against cell seeding and adhering of bacteria, Bacillus subtilis. A multi-walled carbon nanotube/titanium dioxide nano-power was produced via simple mixing of carbon nanotube and titanium dioxide nanoparticles during the sol-gel process followed by heat treatment. Successfully, quercetin was immobilized on the nanocomposite via physical adsorpti...

This work describes the photocatalytic removal of methylene blue from aqueous solution by titanium dioxide nanoparticles under ultraviolet irradiation in a batch system. The effect of operational parameters such as irradiation time, nano titanium dioxide dosage, pH and initial methylene blue concentration were analyzed and optimized by response surface methodology in the nano titanium dioxide/u...

The oxidation of alcohols to carbonyl compounds in a clean fashion (i.e., with water as a solvent or under solvent-free conditions, and using O2 or H2O2 as the primary oxidant) is the subject of considerable research efforts. A new approach for the selective oxidation of soluble aromatic alcohols in water under mild conditions via a novel composite photocatalyst has been developed. The catalyst...

Titanium dioxide (TiO2) nanoparticles are commonly used in sunscreens as part of the formulation to block the sun’s harmful UV rays. As the use of nanoparticles in consumer products has increased, concern has risen as to the health and environmental effects of nanoparticles. Since sunscreens contact skin and wash off in water, the TiO2 nanoparticles can find their way into biological and enviro...
