As-received BaTiO₃ nanopowders of average grain sizes 50 nm and 100 nm were functionalized by (3-aminopropyl)triethoxysilane (APTES) and mixed with poly(methyl methacrylate)/toluene solution. The nanocomposite solution was spin coated on Si substrates to form thin films. The photoluminescence spectrum of the pure powder was composed of a bandgap emission at 3.0 eV and multiple bands centered ab...

surface of mesostructured silica, kit-6, was modified by grafting 3-aminopropyl-triethoxysilane (aptes) to have the positive charge, and thus, to provide sites for the immobilization of h3pw12o40 (pw12).  this modified-nanosized mesoporous silica (pw12-aptes@ kit-6) was characterized by ftir, xrd, bet and tem. the oxidation of sulfides occurs effectively and selectively with h2o2 as the oxidant...

This work demonstrated the effect of functionalized magnesium oxide (MgO) nanoparticles with 3-(aminopropyl) triethoxysilane (APTES) as fillers on mechanical and thermal properties epoxy composite. The functionalization MgO (S-MgO) considerably improved interface between resin. composites revealed that addition their tensile strength, modulus elasticity, ductility when compared to neat epoxy. I...

In  this  work,  a  new  hybrid  organometallic-inorganic  hybrid nanomaterial was prepared by immobilization of acetyl ferrocene on the  surface  of magnetite  nanoparticles. Covalent  grafting of silica coated magnetite nanoparticles (SCMNPs) with 3-aminopropyl triethoxysilane gave aminopropyl-modified magnetite nanoparticles (AmpSCMNPs). Then, Schiff base condensation  of AmpSCMNPs with acet...

Abstract All-inorganic perovskite nanocrystals CsPbX 3 (X=Cl, Br, I) have garnered significant interest due to their promising applications and become a leading research subject in the field of optoelectronics. The weak stability CsPbBrI 2 has hindered development, however, silica coating can effectively solve this problem. (3-aminopropyl) triethoxysilane was used as raw material for synthesis ...
