Abstract A novel Cr-substituted hydroxyapatite (Cr-HA) nanoparticles were synthesized via continuous hydrothermal technique. Moreover, the material was embedded into a silica sol–gel matrix and applied on an AA2024 substrate to evaluate corrosion inhibition efficiency of coating. TEM SEM micrographs confirmed development Cr-HA nanorods 20 nm width 6 µm length. XRD diffractograms demonstrated ev...

This paper introduces a process for the growth of oxide nanorod, nanotube, and nanocable arrays that combines sol preparation and template-based electrophoretic deposition. Examples are shown that the sol electrophoretic deposition is an effective method for the formation of polycrystalline and single crystal oxide nanorod arrays, nanotube arrays and conformal coating of thin films of oxides on...

OBJECTIVE This study investigated the effects of different surface treatments on the tensile bond strength of an autopolymerizing silicone denture liner to a denture base material after thermocycling. MATERIAL AND METHODS Fifty rectangular heat-polymerized acrylic resin (QC-20) specimens consisting of a set of 2 acrylic blocks were used in the tensile test. Specimens were divided into 5 test ...

Planar waveguides of SiO2:TiO2 (multilayer structure) and SiO2:CeO2 (thick layer) were prepared onto commercial glass substrates using a sol-gel technique combined with dip-coating. These glassy coatings were structural characterised by Transmission Electron Microscopy (TEM) Energy Dispersive X-ray analysis and by Confocal Microscopy. Thicknesses of 1230 nm and 4,15 μm and refractive indices of...

Sn-TiO 2 nanocomposite coatings were prepared by sol-gel enhanced electrodeposition technique and the effect of c concentration on performance composite was investigated adding different volumes TiO sol to electrolyte. The microscopic morphology corrosion resistance characterized XRD tests, SEM hardness tests a series electrochemical tests. From test results, it found that coating had highest v...

A spinel LiMn1.5Ni0.5O4 (LMNO) cathode material synthesized by a sol-gel method is modified by MgF2 nano-coating via a wet coating strategy. The results of X-ray diffraction (XRD), Raman spectroscopy, field emission scanning electron microscopy (FESEM) and high resolution transmission electron microscopy (HRTEM) showed that the MgF2 nano-coating layers do not physically change the bulk structur...

In this work it is proposed a novel antibacterial surface composed of an organicinorganic hybrid matrix of tetraethoxysilane (TEOS) and a weak polyelectrolyte like Poly(acrylic acid sodium salt) (PAA) which are deposited on glass slides by sol-gel method using the dip-coating technique [1]. This work is focused in the in situ synthesis of Ag nanoparticles (NPs) which are responsible of the anti...
