The effect of the addition of antimony doped tin oxide (ATO) nanoparticles on the electrical conductivity of acrylate films is described. To enable dispersing of ATO in acrylate matrices, 3-methacryloxypropyltrimethoxysilane (MPS) was grafted on the surface of the filler. The amount of MPS used ...
Objectives. The aim of this study was to evaluate the reactions of silanes prior to attaching the composite to titanium and evaluate these silanes as coupling agents. Veneered titanium may be used as a prosthetic material.Methods. Two silane solutions, a mixture of both γ-methacryloxypropyltrim...
The chain dynamics and the apparent activation energy of dehydration and decomposition of the ester bond for poly(3-methacryloxypropyl-trimethoxysilane-co-vinylimidazole) copolymer (PMPS–PVI), were examined by high-resolution solid-state 29Si and 13C nuclear magnetic resonance spectroscopy and ...
Miniemulsion polymerization offers several advantages over conventional emulsion polymerization to co-polymerize alkoxysilane monomers, which easily undergo premature hydrolysis and condensation reaction into the polymer particles. The premature hydrolysis and the subsequent condensation reactio...

Tin oxide, antimony-doped tin oxide (ATO), and silica nanosized particles in aqueous dispersion were reacted with various amounts of 3-methacryloxypropyltrimethoxysilane (MPS). The kinetics were followed by 29Si NMR and the products were analyzed by FTIR and 29Si NMR. The kinetic experiments on ...
In this work we successfully prepared sol–gel derived organic–inorganic hybrids by the incorporation of poly(2-hydroxyethyl methacrylate) and 3-methacryloxypropyltrimethoxysilane into a silica matrix. The obtained samples were examined by Fourier transform infrared spectroscopy (FTIR), thermog...
Polylactide (PLA) nanocomposites characterized by antimicrobial properties are gaining increasing attention for food packaging. In this contribution, the PLA based nanocomposite films with multifunctional end-use properties were achieved by incorporating ZnO nanoparticles (NPs) [untreated: ZnO(U...
Flexible aerogels from methyltrimethoxysilane (MTMS) and 3-(2,3-epoxypropoxy)propyltrimethoxysilane (GPTMS) were prepared by employing a two-step acid–base sol–gel process along with the use of a surfactant. The alcogels have been aged for one day and two days. The resulting aerogels were flex...
β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane (ECEMS, CAS No. 3388-04-3) is mutagenic in vitro and weakly carcinogenic in mice after dermal application. Timed pregnant Fischer 344 rats and New Zealand white rabbits were dosed with ECEMS in corn oil by gavage on gestational days (gd) 6 through 15...
Chitosan based hybrid membranes were prepared by incorporating 2-(3,4-epoxycyclohexyl) ethyltrimethoxysilane (ETMS) into chitosan matrix using a sol–gel technique. The resulting membranes were studied using Fourier transform infrared spectroscopy (FTIR), wide-angle X-ray diffraction (WAXD), dif...
Features of the metal—ligand interactions of some divalent cations of the first transition series with N-(2-aminoethyl-3-aminopropyl)trimethoxysilane anchored on a silica-gel surface were studied in both ethanol and acetone solution. The adsorption capacity and equilibrium constant for each met...
Cholesterol oxidase (ChOx) has been covalently immobilized onto two-dimensional self-assembled monolayer (SAM) of N-(2-aminoethyl)-3-aminopropyl-trimethoxysilane (AEAPTS) deposited on the indium–tin oxide (ITO) coated glass plates using N-ethyl-N′-(3-dimethylaminopropyl) carbodiimide and N-hyd...
Museum artifacts made of polyurethane foam are frequently affected by conservation issues mainly related to the loss of their mechanical properties. While effective polyurethane ether foam treatments already exist, no convenient consolidation treatment exists for polyurethane ester foams. The po...
We theoretically and experimentally investigated the influence of the Fermi level position of graphene relative to the Dirac point on the performance of a graphene/MoS2 heterojunction barristor. A large Fermi level modulation (ΔEF = 0.28 eV) of graphene, when the VGS is changed between −20 V an...
