Infrared and Raman spectra were recorded for the silane coupling agent (SCA), TFPTMS sol and xerogel. Vibrational assignments have been su...

High-pressure phase behaviour data are reported for the binary systems CO2 + N-[3-(trimethoxysilyl)propyl]aniline (TMSPA) and CO2 + (3-mercaptopropyl)trimethoxysilane (MPTS). The organosilanes TMSPA and MPTS are employed to functionalise with the amino and mercapto groups, respectively, the surf...

Functionalized reduced graphene oxide (RGO) was obtained by reaction of graphene oxide with dodecyl (12C), octyl (8C) and propyl (3C) trimethoxysilane and subsequent reduction using hydrazine hydrate. The results showed the successful grafting of the alkyl groups onto the surface of RGO, and tha...

Polycaprolactone-styrene-vinyl trimethoxysilane terpolymer was prepared and then modified with sunflower oil partial glyceride (SFOPG) via a sol–gel method for use as a binder in coating applications. Therefore, a vinyl-functionalized polyester-based macromonomer (HPCL) was prepared via ring-op...

The hydrosilylation reaction of ethylene gas with trimethoxysilane was investigated and various factors such as the temperature, the reaction time, the dosage of catalyst and the promoter iodine on conversion of trimethoxysilane, and the yield and selectivity of the target product were carefully...

Technological parameters of the ammonolysis of (3-chloropropyl)trimethoxysilane to (3-aminopropyl)trimethoxysilane have been determined. Influence of temperature, reaction time and the molar ratio of ammonia to (3-chloropropyl)trimethoxysilane has been examined. Influence of the parameters has b...

The poorly water-soluble pesticide imidacloprid (IMP) was intercalated into NiZn-layered hydroxide salts (NZL) by the aid of (3-glycidyloxypropyl) trimethoxysilane (GPS). The resulting NZL-GPS-IMP composites were characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (...

A versatile and economic method of preparing covalently-bound and uniform bifunctional silane monolayers on stainless steel is presented. Stainless steel is first electrochemically hydroxylated to enable the formation of a bifunctional overlayer via simultaneous liquid-phase deposition of two or...

Advanced techniques in nanofabrication are essential in order to manifest theoretical works in establishing nanobio-sensor devices. Metal-insulator-metal (MIM) geometry has been effectively used for tuning plasmonic effect that dramatically altered biosensor sensitivity. Normally, adhesive metal...

In this study, (pentafluorophenylpropyl)trimethoxysilane (PFPPS) is grafted on a nickel-doped manganese spinel (LiNi0.5Mn1.5O4, LNMO) surface to suppress the failure modes in the 5-V positive electrode; electrolyte oxidation/film deposition, acid generation, and metal (Ni and Mn) dissolution. Va...

In this work, adsorption characteristics of nano NH2-HMS (functionalized HMS type mesoporous silica with amine groups) for the removal of Pb (II) ions from aqueous solutions were investigated. The adsorbent was characterized using FE-SEM, TEM, XRD, FTIR and BET. The adsorption of Pb (II) ions by...

When the reaction of metallic silicon with methanol in the presence of a small amount of thiophene was carried out at 653 K, methyldimethoxysilane was formed together with trimethoxysilane and tetramethoxysilane, the selectivity for methyldimethoxysilane being 22%. Further adding a small amount ...

A comparative experiment about the 3‑aminopropyl triethoxysilane (APTES) modification of waxy potato starch nanocrystals (WPSNCs) and waxy maize starch nanocrystals (WMSNCs) was employed in the present study. The purpose of surface chemical functionalization was to introduce functional groups an...

To improve the heavy metal adsorption of microcrystalline cellulose (MCC), two successive grafting reactions of silylation by (3-chloropropyl)triethoxysilane (CPTES) and amine-functionalization with metformin HCl were performed and the modified MCC from the first and second steps were denoted as...

A seeding-free synthesis strategy was developed for the preparation of dense and phase-pure zeolite LTA membranes on 3-chloropropyltrimethoxysilane (CPTMS) functionalized supports. Through the functionalization of supports by using CPTMS, the nucleation and growth of a thin, well intergrown zeol...

Nitro compounds are widely used in military and industrial activities including explosives dyes, pesticides, polymers and other active species. The main goal of this work is to present an efficient nanosorbent to remove mg L− 1 of 4-nitroaniline (4NA) and 2-amino-3-nitropyridine (2A3NP) from aqu...

Organophilic pervaporation (OPV) has been considered as one of the most promising separation processes for the recovery of biofuels from fermentation broths, however, in addition to preferred target product – liquid biofuels, the yeast cells and fermentation nutrients could affect the recovery ...

In order to improve the compatibility between magnesium hydroxide (MH) and polymer matrix, the surface of MH was modified using vinyltriethoxysilane (VTES) by dry process and the interfacial interaction between MH and VTES was also studied. Zeta potential measurements implied that the MH particl...

Hydrogen-selective silica membranes were prepared on a macroporous alumina support by chemical vapor deposition (CVD) of vinyltriethoxysilane (VTES) at 873 K at atmospheric pressure. The membrane had a high H2 permeance of 5.4 × 10−7 mol m−2 s−1 Pa−1 with H2 selectivity over CO2, N2, CO and CH4...
