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...

Lithium-ion batteries are commonly used as energy storage devices in a variety of applications. The cathode architectures and materials have a large influence on the performance of lithium-ion batteries, namely power and energy densities. Three-dimensional bicontinuous cathode structures should help improve the charge and discharge rate performances, while maintaining a high energy capacity. By...

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 ...

Ridge and buried channel waveguides were fabricated on different substrates such as SiO2-on-Si, Si, glass wafers and Printed Circuit Boards by a sol-gel processing together with a photolithography process using photopatternable hybrid sol-gel materials. Thick sol-gel films of up to 100 microns were developed using a modified sol-gel process and ridge waveguides with vertical smooth sidewalls we...

the aim of this work is to synthesize and investigate the performance of yttria-doped zirconia solgelcoatings in the chemical corrosion prevention of zircaloy-4 (zirconium alloy) in a 1 n h2so4environment. the influence of four different molar ratios of water to alkoxide, namely 1, 4, 12, and20, on the coating quality and its corrosion prevention performance was investigated. differentialtherma...

Lu₂O₃:Eu3+ transparent, high density, and optical quality thin films were prepared using the sol-gel dip-coating technique, starting with lutetium and europium nitrates as precursors and followed by hydrolysis in an ethanol-ethylene glycol solution. Acetic acid and acetylacetonate were incorporated in order to adjust pH and as a sol stabilizer. In order to increment the thickness of the films a...
