Silane-modified amphiphilic chitosan was synthesized by anchoring a silane coupling agent, (3-aminopropyl)triethoxysilane, to a novel amphiphilic carboxymethyl-hexanoyl chitosan (CHC). The chemical structure of this new organic-inorganic hybrid molecule was characterized by FTIR and 13C-, 29Si-nuclear magnetic resonance, while the structural evolution was examined using scanning electron micros...

Silane-based plasmas are widely used to deposit nanostructured silicon thin films or to synthesize silicon nanoparticles. Dust particle formation in Ar/SiH4 plasmas is a continuous phenomenon: as long as silane precursors are provided, new dust generations are formed. Successive generations can be monitored thanks to various electrical (Vdc/3H) and optical (OES, video imaging) diagnostics. Expe...

GeO2/organically modified silane (ormosils) organic-inorganic composite films containing azobenzene were prepared by combining sol-gel technology and spin coating method. Optical waveguide properties including the refractive index thickness of characterized using a prism coupling instrument. Surface morphology photochemical investigated atomic force microscope Fourier transform infrared spectro...

objective: ceramics have advantages such as optimal esthetics and biocompatibility. however, in the oral environment, they are subjected to high levels of stress due to masticatory forces, saliva, thermal changes and alterations of ph, which increase their risk of fracture. since replacement of these restorations is costly and time-consuming, composite resin is often used for intraoral repair o...

silane to improve the adhesion of phosphate monomer-based (MDP) resin cement to glass ceramic. Resin and feldspathic ceramic blocks (n=48, n=6 for bond test, n=2 for microscopy) were randomly divided into 6 groups and subject to surface treatments: G1: Hydrofluoric acid (HF) 9.6% for 20 s + Silane + MDP resin cement (Panavia F); G2: HF 9.6% for 20 s + Silane + Heat Treatment (oven) + Panavia F;...

Silane coupling agent generally use as improve the properties of white filler use in rubber compound for better dispersion. Also silane coupling agent reacts with organic filler & polymer chain as crosslink. Here in this research study the crosslink density & swelling phenomena of silane participate in vulcanization process with Nitrile rubber compound. Also show the comparisons of carbon fille...

The effects of an ammonia-based catalyst, surface coverage, organofunctional group and chain length on silane adhesion promoter efficacy were examined at a benzocyclobutene (BCB)/silicon dioxide interface with silanes of varying functionality and chain length. Fracture-mechanics-based techniques, and X-ray photoelectron spectroscopy and contact-angle measurements were used to quantify the adhes...
