A facile method to synthesize a TiO2/PEDOT:PSS hybrid nanocomposite material in aqueous solution through direct current (DC) plasma processing at atmospheric pressure and room temperature has been demonstrated. The dispersion of the TiO2 nanoparticles is enhanced and TiO2/polymer hybrid nanoparticles with a distinct core shell structure have been obtained. Increased electrical conductivity was ...

A TiO2 film photoanode with gradient structure in nanosheet/nanoparticle concentration on the fluorine-doped tin oxide glass from substrate to surface was prepared by a screen printing method. The as-prepared dye-sensitized solar cell (DSSC) based on the gradient film electrode exhibited an enhanced photoelectric conversion efficiency of 6.48%, exceeding that of a pure nanoparticle-based DSSC w...

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...

BACKGROUND We study the human serum albumin (HSA) protein-CuO nanoparticle interaction to identify the specific binding site of protein with CuO nanoparticles by molecular docking and compared it with HSA-TiO2 nanoparticle interaction. METHODS The protein structural data that was obtained using Autodock 4.2. RESULTS In case of CuO np-HSA interaction, the distances from the centre of Subdoma...

Dye sensitized solar cell was assembled using TiO2 nanoparticle with argon-nitrogen plasma treatment and CuBi2O4 sputtering electrode prepared by plasma irradiation. The electric property of the solar cell fabricated by plasma treated TiO2 nanoparticle was improved because the physical and chemical property of TiO2 particles affected from the nitrogen plasma treatment

Regularly spaced TiO2 nanotubes were prepared by anodizing a titanium substrate in triethylene glycol electrolyte at elevated temperature. In comparison to conventional TiO2 nanotubes, spaced nanotubes possess an adjustable spacing between the individual nanotubes; this allows for controlled buildup of a hierarchical nanoparticle-on-nanotube structure. Here, we use this principle for layer-by-l...

Titanium dioxide (TiO2) nanoparticles are currently the second most produced engineered nanomaterial in the world with vast usage in consumer products leading to recurrent human exposure. Animal studies indicate significant nanoparticle accumulation in the brain while cellular toxicity studies demonstrate negative effects on neuronal cell viability and function. However, the toxicological effec...

The specific role played by small gold nanoparticles supported on the rutile TiO2( 110) surface in the processes of adsorption and dissociation of H2 is discussed. It is demonstrated that the molecular and dissociative adsorption of H2 on Au(n) clusters containing n = 1, 2, 8 and 20 atoms depends on cluster size, geometry structure, cluster flexibility and the interaction with the support mater...

Density functional theory calculations were carried out to study the interaction of heroin molecule with pristine and N-dopedTiO2 anatase nanoparticles. The oxygen atom of heroin molecule was found to be the binding site on the heroin molecule. In contrast, the binding site of TiO2 nanoparticle was positioned over the fivefold coordinated titanium atoms. The results showed that the adsorption e...

Diarylamines are an important class of widely utilized chemicals, and development of diverse procedures for their synthesis is of great importance. Herein, we have successfully developed novel versatile catalytic procedures for the synthesis of diarylamines through acceptorless dehydrogenative aromatization. In the presence of a gold-palladium alloy nanoparticle catalyst (Au-Pd/TiO2), various s...
