Anatase TiO2 films were successfully prepared on foam nickel substrates by sol-gel technique using tetrabutyl titanate as precursor. The characteristics of the TiO2 films were investigated by XPS, XRD, FE-SEM, TEM and UV-Vis absorption spectra. The photocatalytic activities of TiO2 films were investigated by photocatalytic degradation reactions of gaseous acetaldehyde, an indoor pollutant, unde...

The effect of TiO2 nanoparticle (NP) content on the improvement of poly(9,9′-di-noctylfluorenyl-2,7-diyl) (PFO)/Fluorol 7GA organic light emitting diode (OLED) performance is demonstrated here. The PFO/Fluorol 7GA blend with specific ratios of TiO2 NPs was prepared via a solution blending method before being spin-coated onto an indium tin oxide (ITO) substrate to act as an emissive layer in OLE...

Emission of N2O from mobile and off-road engine is now being currently regulated because of its high impact compared to that of CO2, thereby implying that N2O formation from the exhaust gas after-treatment system should be suppressed. Selective catalytic reduction using vanadium supported TiO2 catalyst in mobile and off-road engine has been considered to be major source for N2O emission in the ...

The aim of this work was to investigate corrosion resistivity, bioactivity, and antibacterial activity novel nano-amorphous calcium phosphate (ACP) potentially multifunctional composite coatings with without chitosan oligosaccharide lactate (ChOL), ACP + ChOL/TiO2 ACP/TiO2 ChOL/TiO2, respectively, on the titanium substrate. were obtained by new single-step in situ anodization substrate generate...

Sensitive determination of Cr(VI) is great importance as this one the most toxic heavy metal ions in environment. In work, a metal–organic framework (MOF) material, UIO-66 (University Oslo, UIO), was introduced for first time to develop composite substrate, UIO-66/Ag/TiO2, sensitive SERS detection water. The composition, morphology, crystal structure and optical property UIO-66/Ag/TiO2 were cha...

In this study, Al2O3, TiO2 and Al2O3+ 3wt%TiO2 coatings were deposited on AZ31 Mg alloy substrate by plasma spraying. The structurally characterized scanning electron microscopy X-ray diffraction. Corrosion experiments carried out in 3.5% NaCl solution. Adhesion tests performed according to daimler benz VDI-3198 standard. A coating layer of approximately 70 microns thickness was deposited. High...

The cold spraying of ceramic materials is widely acknowledged as a difficult process because it necessitates the feedstock powder particles experiencing plastic deformation for deposition on substrate. problem arises due to brittle properties such titanium dioxide (TiO2), combined with lack understanding bonding mechanisms. In this study, TiO2 coatings were deposited onto copper and aluminum su...

Laser interference lithography is an established fabrication technique for periodic arrays such as photonic crystals (PCs). In this paper, we report the fabrication of a TiO2-organic hybrid periodic array by nanosecond laser interference lithography. TiO2organic hybrid films were prepared from titanium tetra-n-butoxide and 2-(methacryloyloxy) ethyl acetoacetate (MEAcAc) by the sol–gel method. T...

In this study, the P25 titanium dioxide (TiO2) nanoparticle (NP) thin film was coated on the fluorine-doped tin oxide (FTO) glass substrate by a doctor blade method. The film then compressed mechanically to be the photoanode of dye-sensitized solar cells (DSSCs). Various compression pressures on TiO2 NP film were tested to optimize the performance of DSSCs. The mechanical compression reduces Ti...
