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...

The reactive tissue response of the brain to chronically implanted materials remains a formidable obstacle to stable recording from implanted microelectrodes. One approach to mitigate this response is to apply a bioactive coating in the form of an ultra-porous silica sol-gel, which can be engineered to improve biocompatibility and to enable local drug delivery. The first step in establishing th...

: In this study we fabricated Zinc Oxide thin film by sol-gel dip coating method on glass substrate. X-ray reflectivity (XRR) and its optimization have been used for characterization and extracting physical parameters of the film. Genetic Algorithm (GA) has been applied for this optimization process. Independent information was exploited from Fourier transform of Fresnel reflectivity normalized...

Titanium oxide coatings have been deposited by the sol-gel dip-coating method. Crystallization of titanium oxide coatings was then achieved through thermal annealing at temperatures above 400 °C. The structural properties and surface morphology of the crystallized coatings were studied by micro-Raman spectroscopy and atomic force microscopy, respectively. Characterization technique, based on le...

To improve the corrosion protection of copper metal, 0.01M concentration of 1H-1,2,4-triazole-3-thiol (TAT) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (GPTMS) and Tetraethoxysilane (TEOS). It was further subjected to hydrolysis and condensation reaction to form a sol-gel matrix. The TAT-doped hybrid sol-gel coating was applied over the c...

The sol-gel method provides a wide variety of applications in the medical field. One these is formation coatings on metal implants. containing specific additive can enhance or improve existing surface properties substrate. In this work, titania were doped with two forms silver (AgNO3, Ag3PO4) and synthetic hydroxyapatite applied titanium samples by dip-coating technique. After drying slow firin...

We measured the complex capacitance C( f ) of ITO/sol-gel alumina/Al capacitors deposited on glass (and some on stainless steel foil) in the frequency range 15 Hz–10 MHz. The sol-gel films were deposited by dip-coating and following a two step process. The capacitance C( f ) found was much higher than that of a pure Al2O3-film due to the remaining porosity of the film and the uptake of H2O from...

Zn1-xMgxO (x=0.00, 0.01, 0.02, 0.03, 0.04 and 0.05) solutions were prepared by sol-gel synthesis using acetate precursors which were dissolved into different solvents of ethanol, methaol, 2methoxyethanol and chelating agents of monoethanolamine, diethanolamine and triethanolamine . Syntehsized particles were then annealed at various temperatures and times and were observed for effect of doping ...
