Nanofibers, produced by electrospinning a solution containing titanium tetra(IV) isopropoxide, polyvinyl acetate and acetic acid in N,N-dimethyl acetamide, upon sintering at 500 °C produce rice grain-shaped TiO(2) mesostructures. Each rice grain-shaped TiO(2) has a mixed crystal structure and high porosity and the mesostructures are found to have applications in dye-sensitized solar cells.

Abstract Lithium aluminium hydride (LiAlH 4 ) is an outstanding complex metal as a hydrogen storage material. The capacity of LiAlH4 about 5-7 wt%. In this study, concentration 20 g/l doped with various titanium (Ti) by dip coating method was examined. dioxide (TiO 2 powder at 10 mol % 25 and 40 used the Ti source. Instruments to analyze Ti-doped LiAlH were X-ray diffraction (XRD) scanning elec...

Titanium dioxide (TiO 2 ) nanotubes array with the length of 16 μm and outer diameter 100 nm were synthesized by anodic oxidation titanium foil in an electrolyte solution containing a fluorine-containing ethylene glycol. The selected synthesis conditions make it possible to separate nanotubular from study as homogeneous functional material. performed scanning electron microscopy Brunauer--Emmet...

PURPOSE The characteristics of oxidized titanium (Ti) surfaces varied according to treatment conditions such as duration time and temperature. Thermal oxidation can change Ti surface characteristics, which affect many cellular responses such as cell adhesion, proliferation, and differentiation. Thus, this study was conducted to evaluate the surface characteristics and cell response of thermally...

The results of studies the optical and photocatalytic properties titanium oxide films deposited by vacuum-arc evaporation in an oxygen-containing atmosphere are presented. It was experimentally shown that different degrees oxidation formed during deposition, depending on amount oxygen flow entering working chamber. obtained showed a transitional mode between deposition metallic Ti dielectric Ti...

Today, significant attention has been brought to the development of sensitive, specific, cheap, and reliable sensors for real-time monitoring. Molecular imprinting technology is a versatile and promising technology for practical applications in many areas, particularly chemical sensors. Here, we present a chemical sensor for detecting formaldehyde, a toxic common indoor pollutant gas. Polypyrro...

Atomic layer deposition (ALD) technology is introduced to fabricate a high sensitivity refractometer based on an adiabatic tapered optical fiber. Different thicknesses of titanium dioxide (TiO₂) nanofilm were coated around the tapered fiber precisely and uniformly under different deposition cycles. Attributed to the higher refractive index of the TiO₂ nanofilm compared to that of silica, an asy...

The performance of a modified electrode of nanocomposite films consisting of polypyrrole-chitosan-titanium dioxide (Ppy-CS-TiO₂) has been explored for the developing a non-enzymatic glucose biosensors. The synergy effect of TiO₂ nanoparticles (NPs) and conducting polymer on the current responses of the electrode resulted in greater sensitivity. The incorporation of TiO₂ NPs in the nanocomposite...
