Titanium dioxide/single-walled carbon nanotube (TiO2/SWNT) composites were prepared for photocatalytic applications. The composites were characterized using UV-visible and Raman spectroscopy, zeta-potential measurements, cyclic voltammetry (CV) coupled with a photoreactor, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) coupled with energy dispersive x-ray spectros...

TiO2 anatase nanowires have been prepared by a hydrothermal process followed by post-heat treatment in air. TiO2 nanoparticle/TiO2 nanowire composite electrodes were prepared for dye-sensitized solar cells (DSC) in order to improve light-to-electricity conversion efficiency. The TiO2 NP/TiO2 NW composite cells showed higher DSC performance than ordinary nanoparticle cells and fully nanowire cel...

In this work, TiO2/Ti composite films were fabricated by 2-setp MCT and the following high temperature oxidation. Antibacterial activity of the composite films treated by ultrasonic cleaning to increase the performance reliability was examined. The prepared TiO2/Ti composite films showed high photocatalytic activity in the degradation of methylene blue solution. It is obvious that TiO2/Ti compo...

TiO2 nano-particles were used in electroless plating bath to obtain Ni/P/nano-composite coatings. The coatings were heat treated at 200, 400, 600 and 700 oC and their chemical and physical properties were investigated and it was found that 400 oC was the optimum temperature for the heat treatment of the coatings. The micro-hardness test of coatings showed that t...

Glass/ceramic composite coatings were prepared on 40Cr steel matrix by thermo-chemical reaction with fly ash and a small amount of SiO2, Al2O3, MgO, and albite as main raw materials. On this basis, adding 10% Al-TiO2-B2O3 exothermic system, the morphology, phase, thermal shock resistance, and corrosion resistance of the coating were tested, and the influence of exothermic system on the structur...

luminium based composite are getting a vast scope nowadays because of its properties and availability. In the present work, fly ash and AL2O3 reinforced composite are prepared using stir casting technique for varying wt.% (fly ash 3% and AL2O3 3%, 6% & 9%). Hardness and tensile properties were determined, with the addition of reinforcement the properties are improved compared to the parent meta...

In this work, a blending strategy based on compounding the hydrophilic titanium dioxide (TiO2) particles with the host polypropylene (PP) pellets, followed by the common membrane manufacture process of melt extruding/annealing/stretching, was used to improve the polarity and thus electrolyte uptake capability of the PP-based microporous membranes. The influence of the TiO2 particles on the crys...

In this study, mechanically milled (MM) Al-24TiO2-20B2O3 powder in molten Al7075 matrix was used order to fabricate in-situ TiB2 and Al2O3 reinforcements matrix. Differential thermal analysis (DTA) examination adopted find reaction temperature between Al, TiO2, B2O3 powders. X-Ray Diffraction (XRD) patterns showed the existence of peaks (750 °C at Ar atmosphere) MM powder. Scanning Electron Mic...
