A high-stability Eu-complex has been achieved by coating with a silica glass via a low temperature sol-gel process using deuterated methanol. A three-dimensional glass network protects Eu-complex from free-oxygen and/or water to change the ligand structure. In addition, the chemical bond of deuterated Eu-complex is more stable than that of the conventional Eu-complex. Therefore, we achieved the...

This paper develops a simple and versatile analytical method for characterizing residual stress associated with the deposition of thick, thin, single multilayer coatings. study is great importance, since generation can lead to formation significant defects in coating. To illustrate effectiveness our method, two different processes were characterized. The coatings formed are intended anti-corros...

Lead Zirconate Titanate oxide (PZT) thick films with thicknesses of up to 10 μm were developed using a modified sol-gel technique. Usually, the film thickness is less than 1 μm by conventional sol-gel processing, while the electrical charge accumulation which reveals the direct effect of piezoelectricity is proportional to the film thickness and therefore restricted. Two approaches were adopted...

Applying cells in a spray can overcome current hurdles in coating tissue engineered constructs with a thin layer of endo- or epithelial cells. We report here a structured study on the influences of spray application with a medical spray device on vascular smooth muscle cells (vSMCs) and respiratory epithelial cells (RECs) with and without fibrin gel. Next to viability and cytotoxicity assays, t...

The mixed oxide Zn1-xMgxO (x=0.01-0.2) were prepared by sol-gel synthesis using metal-organic precursors. Zn1-xMgxO films were grown on glass substrates using sol-gel deep and spin coating. Different thickness of films, annealed at various temperatures, were tried to observe the thickness and temperature effects on structural properties. The surface morphologies of all samples were characterize...

Pb(Zr,Ti)O3 compositions are under investigation for applications that include integrated capacitors, piezoelectric sensors, and actuators. Sol–gel synthesis and spin coating are popular routes to the formation of high quality, dense, crack free, insulating films. However, the electrical properties of the films are often different than those measured for bulk specimens of the same composition. ...

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...

This work presents a structural investigation of lithium borate (LBO) thin film. Firstly, 100 nm SiO2 was grown on top of n–type Si substrate by dry oxidation. Secondly, LBO gel was prepared by sol–gel method. After it, thin film of LBO was deposited on functionally graded SiO2/Si stack by spin coating, and then Raman and infrared spectra were studied for different thickness of the LBO film. Go...

Hydroxyapatite (HAp) is commonly used to coat titanium alloys (Ti-6Al-4V) for orthopedic implants. However, their poor adhesion strength and insufficient long-term stability limit their application. Novel sphene (CaTiSiO5) ceramics possess excellent chemical stability and cytocompatibility. The aim of this study is to use the novel sphene ceramics as coatings for Ti-6Al-4V. The sol-gel method w...
