Ultrathin nanocomposite films were prepared on solid supports via adsorption of organic and inorganic molecules from solution. Coordination geometry for transition metal ions was preserved by embedding metal ligands into titanium oxide gel films, and porous titanium oxide films were prepared by selective removal of organic components from polymer/metal oxide composite films using oxygen plasma ...

The design and optimization of a nanostructured antireflective coatings for Si solar cells were performed by using response surface methodology (RSM). RSM was employed to investigate the effect on overall optical performance silicon coated with three different nanoparticle materials titanium dioxide, aluminum oxide, zinc oxide nanostructures. Central composite used reflectance process study mai...

In the current research project, sol-gel electrophoresis technique was utilized to grow titanium dioxide (TiO2) nanotubes. A titanium sol was prepared using organometallic precursors of titanium to fill the template channels. The prepared solwas driven into nanopores of porous anodic aluminum oxide templates under the influence of a DC electric field to form nanotubes on the pore walls. Tube fo...

objective(s): titanium dioxide (tio2) nanoparticles (nps) are widely used in commercial food additives and cosmetics worldwide. uptake of these nanoparticulate into humans by different routes and may exhibit potential side effects, lags behind the rapid development of nanotechnology. thus, the present study designed to evaluate the toxic effect of mixed rutile and anatase tio2 nps on serum bioc...

In this work, the fabrication of single titanium oxide nanodot (ND) resistive sensors for NO gas sensing at room temperature is reported. Two atomic force microscopy nanolithography methods, nanomachining and nano-oxidation, are employed. A single titanium nanowire (NW) is created first along with contact electrodes and a single titanium oxide ND is subsequently produced in the NW. Gas sensing ...

The purpose of this study was to investigate the correlation between corrosion resistance and surface composition of an experimental Ti-20 mass% Cr casting alloy in a saline solution containing fluoride. The alloy had a greater resistance to corrosion in a fluoride-containing saline solution than did commercially pure titanium. However, with confirmed dissolution of titanium and chromium, it me...

introduction: the aim of this animal study was to evaluate the histological response of the new nano zinc-oxide eugenol (nzoe) sealer in comparison with pulp canal sealer (zoe based) and ah-26 (epoxy resin sealer). methods and materials: a total of 27 wistar rats were used. four polyethylene tubes were implanted in the back of each rat (three tubes containing the test materials and an empty tub...

Density functional theory calculations were performed to investigate vitamin C interaction withN-doped TiO2 anatase nanoparticles. The adsorption of vitamin C on the energy favorable fivefoldcoordinated titanium sites was investigated. Various adsorption geometries of vitamin C towardsthe nanoparticle were examined. Since the adsorption energies of N-doped nanoparticles are higherthan those of ...
