Hybrid scaffolds based on bioactive glass (BAG) particles (<38 µm), covalently linked to gelatin (G*) using 3-glycidoxypropyltrimethoxysilane (GPTMS), have been studied for bone bioengineering. In this study, two compositions (13-93 and 13-93B20 (where 20% of the SiO2 was replaced with B2O3)) were introduced in matrix. The Cfactor (gelatin/GPTMS molar ratio) kept constant at 500. hybrids obt...

In the present study, chitosan/carboxymethyl cellulose/silica hybrid membrane (CS/CMC/Silica) was prepared by using chitosan and carboxymethyl cellulose in the presence of 3-glycidoxypropyltrimethoxysilane (GPTMS) as the crosslinking agent and used to remove Cr(VI) iron in effluent. The structure of CS/CMC/Silica hybrid membrane was characterized by FT-IR spectroscopy and scanning electron micr...

The thermal conductivity of epoxy resin composites filled with combustion-synthesized hexagonal boron nitride (h-BN) particles was investigated. The mixing of the composite constituents was carried out by either a dry method (involving no use of solvent) for low filler loadings or a solvent method (using acetone as solvent) for higher filler loadings. It was found that surface treatment of the ...

SiO2 is widely used in nanocomposites as reinforcement nanoparticle to enhance mechanical properties especially wear resistivity. Prior use, surface modification with proper and sufficient coupling agent should be performed on it. Coupling concentration plays a key role process. In this study, the influence of 3-(glycidoloxy propyl) trimethoxy silane (GPTMS) nanoparticles, experimentally invest...

This research presents the interaction of the epoxy polymer diglicydil ether of bisphenol-A (DGEBA) with silica (SiO₂) nanoparticles plus zirconia (ZrO₂) nanoparticles obtained via the sol-gel method in the synthesis of an epoxy-silica-zirconia hybrid adhesive cured with polyamide. ZrO₂ nanoparticles were added to the epoxy-silica hybrid adhesive produced in situ to modify the apparent shear st...

Abstract Mesoporous silica was prepared using sodium silicate as a precursor and Cetyl Trimethylammonium Bromide (CTAB) templating agent. The adsorption ability of enhanced by DMA (dimethylamine) modifier glycidoxypropyltrimethoxysilane (GPTMS) linking compound. process carried out incorporating the chloride solution into DMA-modified mesoporous silica, followed desorption flowing acid solution...

Bu çalışmada, kaliks[4]aren temelli grafen oksit (GO-Epoksi-C[4]CN), öncelikle grafit tozundan Hummers metodu kullanarak oksitin (GO) sentezlenmesi ve (3-glisidoksipropil)trimetoksisilan (GPTMS) ile etkileştirilerek epoksi ucundan p-ter-bütilkaliks[4]aren dinitril türevinin bağlanması elde edildi. Sentezlenen bileşiklerin karakterizasyonları, 1H NMR FTIR analizleri gerçekleştirildi. Elde edilen...
