Hydroxyapatite (HA) powders are ultrasonically dispersed in the precursor of fluoridated hydroxyapatite (FHA) or fluorapatite (FA) to form a "colloidal sol". HA/FA biphasic coatings are prepared on Ti6Al4V substrate via dip coating, 150 degrees C drying and 600 degrees C firing. The coatings show homogenous distribution of HA particles in the FA matrix. The relative phase proportion can be tail...

A scalable technique for making silica coatings with embedded two-dimensional arrays of iron oxide nanoparticles is presented. The iron oxide nanoparticle arrays were formed by depositing quasi-crystalline ferritin layers, an iron storage protein with an iron oxide mineral core, on solid substrates by a spread-coating technique based on evaporation-induced convective assembly. The layer of prot...

However, they susceptible to corrosion and cavitation erosion aggressive environments due high concentration copper. Sol-gel coatings the field prevention emerging. Improved thickness significantly improves barrier effect coatings, thereby improving operational-life industrial applications. To da...

This work presents a novel method for direct desorption/ ionization of analytes from sol-gel-derived film. 2,5-Dihydroxy benzoic acid (DHB), a common MALDI matrix, was incorporated into a sol-gel polymeric structure. The sol-gel-derived DHB thin film can assist the mass analysis of analytes by laser desorption/ionization, with a matrix interference-free background in the mass spectra. The sol-g...

Abstract The ferritic-martensitic 9Cr-1Mo steel was coated with a sol-gel ZrO2-3%molY2O3 solution by dip-coating. protective properties of the coating were evaluated in contact Solar Salt for CSP applications. and uncoated steels tested at 500 °C 2000 h. Gravimetric, microstructural compositional studies performed to compare their behaviour, against corrosion. Results revealed beneficial influe...

Herein, a numerical analysis of 1 × 2 demultiplexer based on silica-titania integrated photonics platform is conducted via the finite element method. The structure composed two coupled racetrack microrings (RTMRs) and subwavelength grating (SWG) for demultiplexing 1310 nm 1550 telecommunication wavelengths. material selected this design highly attractive due to its refined optical, physical, ch...

In the past decades, many methods have been developed to synthesize zero- dimensional  nanoparticles, quasi–one–dimensional (1D) CuO nanostructures, such as metal organic deposition technique,  microwave irradiation, sol-gel-like dip  technique, reverse micelle-assisted route, chemical method, and simple template free solution route. Among those synthesis methods, hydrothermal and chemical reac...

This paper aims to develop a novel method, i.e., sol-gel combined with layer-by-layer assembly technology, to impart flame retardancy on polyacrylonitrile (PAN) fabrics. Silica-sol was synthesized via the sol-gel process and acted as cationic solution, and phytic acid (PA) was used as the anionic medium. Flame-retardant-treated PAN fabric (FR-PAN) could achieve excellent flame retardancy with 1...
