In this manuscript, for the first time, we report a combination of electrophoretic and sintering approaches for introducing gold nanoparticles into nanoporous TiO2 films to generate 'hot' electrons resulting in a strong enhancement of photocurrent. The Au-TiO2 nanocomposite material was prepared by the electrophoretic deposition of gold nanoparticles into a porous nanoparticulate titanium dioxi...

Nanofluids are kinds of fluids engineered by dispersing nanoparticles in base fluids, a new challenge for thermal sciences provided by nanotechnology. Due to their excellent characteristics, nanofluids find wide applications in enhancing heat transfer. This paper presents synthesis and characterization of TiO2-CNTs nanocomposites by sonochemical method and investigation of some properties...

Nanosized semiconductors and metals [1, 2] are extensively studied due to their unusual catalytic and opto-electronic properties, ultimately traceable to the large fraction of atoms residing at the surface compared to the bulk, and to confinement of charge carriers inside a small volume of material. At present, major goals in modern material chemistry are represented by the ability to design, f...

TiO2@SBA-15 mesoporous nanocomposite are of increasing interest as materials for photocatalytic applications. We report here an investigation on the characteristics of TiO2@SBA-15 prepared by introducing titanium by a grafting technique. The samples, having TiO2 loadings of 10%, have been characterized by XRF, XRD, FT-IR (CO adsorption), porosimetry, SEM, HRTEM, and UV-Visible diffuse reflectan...

introduction: biodegradable films for food packaging applications have attracted an increasing amount of consideration over the last two decades, predominantly due to environmental pollution and the realization that our petroleum resources are not infinite. starch, which is one of the natural biopolymers, has been considered as one of the best candidates primarily because of its processbility, ...

tio2/zro2 nanocomposite was obtained by the sonochemical technique. in this method, two separate gels containing zirconium and titanium were prepared and mixed together. the precursor sol of zirconium was prepared from an aqueous solution of zrcl4. the precursor titanium tetra isopropoxide (ttip) dissolved in isopropanol. mixing of titanium and zirconium gels was resulted in a yellow tio2/zro2 ...

TiO2 /Fe3O4 nanocomposites with various TiO2:Fe3O4 ratios were synthesized by an ultrasonic-assisted deposition-precipitation method and their UV-light decolorization of Congo dye and magnetic separation were investigated. The nanocomposite samples were characterized by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), surface area analayzer (BET) and Fourier transform infrare...

The data presented in this article are related to the research article entitled "Smart photo-induced silicone/TiO2 nanocomposites with dominant [110] exposed surfaces for self-cleaning foul-release coatings of ship hulls" (Selimet al., 2016) [1]. This article reports on successfully designing and controlling TiO2 spherical single crystal photo-nanofillers and indicating evidence of fouling resi...

We report a simple yet effective approach for the decoration of the TiO2 nanocrystal surface with size-tunable CuO nanodots for high-performance noble metal-free photocatalytic H2 production. Modification with polyacrylic acid enables the surface of TiO2 nanocrystals to be selectively deposited with Cu(OH)2 nanodots, which can be subsequently converted to CuO through dehydration without changin...

Drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. There are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. The present work aims are study on the modified drilling mud properties by using the ...
