Immobilization of gold nanoparticles on planar surfaces is of great interest to many scientific communities; chemists, physicists, biologists, and the various communities working at the interfaces between these disciplines. Controlling the immobilization step, especially nanoparticles dispersion and coverage, is an important issue for all of these communities. We studied the parameters that can...

The paper is devoted to the development and performance testing of a soil conditioner based on leonardite humic substances (LHS) modified with 3-aminopropyltriethoxysilane (APTES). HS were obtained by adding APTES LHS solution at different mass ratios APTES, followed investigation siloxane structures using 31Si NMR spectroscopy. Urbic Technosol was used as model soil. size amount water-stable a...

Abstract Contamination with pathogens degrades water quality and is a major cause of many waterborne diseases. The aim this research to reduce the global disease burden by presenting an efficient, durable, low-cost ceramic filter impregnated actinomycetes-mediated silver nanoparticles (AgNPs) for disinfection in rural areas. This marks first report on simultaneous biosynthesis AgNPs utilizing c...

This reaserch aims at functionalizing magnetic mesoporous silica with methacrylic acid-3-aminopropyltriethoxysilane (Fe3O4@MCM-41@MAA-APTES) applied for removal of methylene blue from aqueous solution. Several variables (such as pH, dye concentration, adsorbent amount and contact time) have been investigated. Under optimum conditions, maximum capacity of 87.71 mg g-1 of MB was obtained for the ...

this article presents an experimental investigation on effects of morphology of nanoparticles on the viscosity nanofluids (nfs). water and ethylene glycol were used as base fluids. a two step method was used for preparation of nfs. sio2 nanoparticles, cnt and graphene nano sheets were dispersed in the base fluids separately with the volume fraction ranging from 0.05% to 1.5%. stability of the n...

The goal of this work is to investigate the effectiveness amorphous SiO2−FexOy loaded by functionalization with Ce(SO4)2, Li2SO4, and 3-aminopropyltriethoxysilane (APTES) for CO2 adsorption. Silica iron-based materials are gaining popularity due their wide range applications, such as catalysis, photocatalysis, imaging, etc.; however, there very few studies regarding adsorption aforementioned ma...

There has been much recent interest in polysaccharide coatings for biotechnology applications. We obtained highly wettable dextran coatings applied to flat silicon wafer surfaces through a two-step process: in the first step, the silicon is aminated by the deposition of a selfassembled monolayer of 3-aminopropyltriethoxysilane (APTES); in the second step, polydisperse and low dispersity dextran...

2,4,6-Trinitrotoluene (TNT) is a widely used nitroaromatic explosive with significant detrimental effects on the environment and human health. Its detection is of great importance. In this study, both electrochemiluminescence (ECL)-based detection of TNT through the formation of a TNT-amine complex and the detection of TNT through electrochemiluminescence resonance energy transfer (ECRET) are d...

In this work, Graphene/Copper Nanowire (G/CuNW) based transparent conducting electrodes (TCEs) were prepared via spin-assisted layer-by-layer (LBL) deposition. 3-aminopropyltriethoxysilane (ɣ-APS) functionalized glass substrates sequentially spin-coated with graphene oxide (GO) and CuNWs. Then, to enhance the electrical conductivity, multilayer films subjected chemical reduction thermal anneali...

We present a dextran modified silicon microring resonator sensor for high density antibody immobilization. An array of sensors consisting of three sensor rings and a reference ring was fabricated and its surface sensitivity and the limit of detection were obtained using polyelectrolyte multilayers. The mass sensitivity and the limit of detection of the fabricated sensor ring are 0.35 nm/ng mm a...
