The polycrystalline SrTiO3 thin films were prepared by the sol-gel-hydrothermal method on glass substrates. synthesis pathway was initiated preparing a clear TiO2 solution using sol-gel method. This then deposited substrate dip coating technique, followed transformation of layer into hydrothermal crystal structure, bond interactions, and band gap energy layers characterized X-ray Diffraction (X...

in this study, mixed metal oxides al2o3/mgo/tio2 coatings with al/mg/ti ratio of 5:1:3 and 2.5:3:4 were coated on aluminum by sol-gel method. the surface morphology, phase analysis, thermal behavior and the corrosion behavior of the al2o3/mgo/tio2 coatings were characterized by (sem), (xrd), (tg-dta) and potentiodynamic polarization test in 3.5 wt.% nacl solution. the results demonstrated that ...

The paper proposes a novel approach to increase the performances of sol–gel coating for biomedical applications. In particular, ultrasonic vibration-assisted turning in combination with cryogenic cooling is explored first time generate complex and isotropic texture more prone be coated, and, turn, less corrosion susceptible compared corresponding surfaces generated through conventional machinin...

Cadmium doped zinc oxide is a promising optical material to enhance the luminescence for possible applications in luminescent devices. The Cd0.1Zn0.9O thin films were deposited on the alumina substrates by the sol gel spin coating method using three different solvents viz. methanol, ethanol and isopropanol. The prepared thin films are preheated at 250° C after each coating and annealed at a tem...

A novel optical fiber humidity sensor based on lossy mode resonances (LMR) has been developed. LMRs are supported here by a thin Indium Tin Oxide (ITO) coating fabricated onto an optical fiber core via a sol-gel dip coating. ITO coated optical fiber devices present a resonant maximum absorption peak in the infra-red region which is shifted to higher wavelengths when the refractive index of the ...
