BACKGROUND The main objective of this study was to examine the photocatalytic degradation of phenol from laboratory samples and petrochemical industries wastewater under UV radiation by using nanoparticles of titanium dioxide coated on the inner and outer quartz glass tubes. METHOD The first stage of this study was conducted to stabilize the titanium dioxide nanoparticles in anatase crystal p...

Sol–gel coatings can provide anti-fouling and erosion resistance while being safe to use in the marine environment. MAPTMS/ZPO multilayer deposited on AA2024-T3 aluminium surface using dip-coating method at three different thicknesses (2, 4, 6 µm) are investigated this work. The characterised terms of physical mechanical properties, these properties comparison previously obtained cavitation lev...

Metallic biomaterials such as 316L stainless steel (SS316L) are widely used an implant to replace the function of damaged bone, especially in hip or knee applications. However, many them fail during a short period have complications. The biocompatibility issues main factor that caused this failure. Thus, coating SS316L with bioactive and biocompatible material is one promising techniques enhanc...

   High transparent conductive indium tin oxide/titanium dioxide (ITO/TiO2) nanostructured thin film is prepared by sol-gel dip-coating technique. This method yielded monodisperse ITO nanoparticles with mean diameter of 12 nm. The atomic composition of the Sn within the ITO structure changed from 0-20 wt.%. Through controlled annealing temperature at 550 oC, the result...

Introduction. Polybrominated diphenyl ethers (PBDEs) are undoubtedly the most important group of organohalogenated compounds that captures the attention of environmental scientists in recent years. PBDEs are widely used flame retardant additives in polymers and textiles and are present in nearly all of our daily appliances. There are growing evidences that these brominated flame retardants are ...

The purpose of this work was to production of ceramic thin films by using of Sol-Gel process. For this purpose deposition of SiO2 on substrates of soda-lime glasses has been carried out. Coating treatments on prepared specimen were conducted in a Sol solution by means of dipping at various times. After drying and performing appropriate heat treatment on each sample, the thickness of coated laye...

this work is aimed to evaluate the role of nanoclay in the protective performance of an eco-friendly silane sol-gel layer applied on mild steel substrate in 0.1m sodium chloride solution. at the first step, the effect of ph of the silane solution, consisting of a mixture of γ-glycidoxypropiltrimethoxysilane and methyltriethoxysilane and tetraethoxysilane, on the coating performance was evaluate...

The technologies of optical planar evanescent wave chemical and biochemical sensors require chemically resistant, high refractive index waveguide films having very good transmission properties. In this paper we present such two-compound SiOx:TiOy fabricated by using the sol-gel method dip-coating technique. These not only have quality low propagation losses but also an extremely >1.90 (? = 6...

3 | P a g e Abstract This thesis is concerned with the synthesis and characterisation of TiO2 based photocatalyst thin films and the assessment of their antimicrobial properties. When exposed to light of wavelength less than 380 nm TiO2 films can demonstrate self-cleaning and self-disinfecting properties. This is due to photocatalytic processes occurring on the film surface resulting in film su...

Abstract:In the present research, SiO2–TiO2 nanostructure films were successfully prepared on windshields using the sol–gel technique for photocatalytic applications. To prevent the thermal diffusion of the sodium ions from the glass to TiO2 films, the SiO2 layer was pre-coated on the glass by the sol–gel method. The substrates were dipped in the sol and withdrawn with the speed of 6cm/min-1 to...
