We report on the synthesis, morphology, chemically and structurally of TiO2-NiO-SiO2 nanostructure. The TiO2-NiO-SiO2 nanostructure was synthesized by a method based on the sol-gel method, by the simultaneous gelation of all cations. The coatings were deposited on dried soda-lime glass slides by spin coating. Composite powders and coating on glass hav...

In this work, Poly(ethyleneterephthalate) (PET) substrate was treated using KOH solution and was modified using hybrid O-I coating containing PCL )polycaprolactone( as organic phase and TEOS )tetraethoxysilane( as inorganic phase. The coating was prepared through a sol-gel process and applied on the surface by dip coater. Then, electrically conducting polythiophene (PTh) nanoparticles were depo...

Nanostructured alumina thin films were coated on stainless steel by Sol-Gel dip coating method. In order to prevent crack formation, Al2O3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. Effects of calcination temperature and withdrawal speed on structural properties were analyzed using XRD and SEM. Topography and thickness of coat...

osseointegration has been the concern of implantology for many years. researchers have used various ceramic coatings for this purpose; however, piezoelectric ceramics (e.g., barium titanate [bto]) are a novel fi eld of interest. in this regard, bto (batio3 , bto) coating was fabricated by electrophoretic deposition on ti6al4v medical alloy, using sol-gel-synthesized nanometer bto powder. struct...

This article presents results of a study on coating of a polymeric substrate catalyst on metallic surface. Stability of coating on metallic surfaces is a proper specification. Sol-gel technology was used to synthesize adhesion promoters of polysilane compounds that act as a mediator. The intermediate layer was coated by synthesized sulfonated polystyrene-divinylbenzene as a catalyst for product...

Uniform nanostructure coating of TiO2 was prepared on 316L stainless steel by sol-gel method using Tetra-n-Butyle Titanat (TBT) as alkoxide material. 316L specimens were coated with the mentioned sol by dip coating method. The influences of preparation condition, pH of sol on TiO2 nanostructure coating were investigated. Their structural properties were examined at var...

PURPOSE To develop a contact lens capable of releasing antibiotics for a minimum of 8 hours for the treatment of bacterial keratitis. METHODS Fibrin gel was loaded with vancomycin or gentamicin and then shaped into a curved disc. The disc was then used to coat the surface of a commercial contact lens or was sealed between two lenses. Separate contact lenses were soaked in solutions of vancomy...

Elastomeric membranes that contained regular arrays of well-defined holes were formed by spin-coating a prepolymer onto a photolithographically defined master. These membranes were used as dry resists or as masks in dry lift-off to produce simple features as small as 5 μm on both planar and nonplanar surfaces. These procedures were “dry” because the membranes conformed and sealed reversibly to ...
