Cationic latex particles with surface amino groups were prepared by a multistep batch emulsion polymerization. In the first one or two steps, monodisperse cationic latex particles to be used as the seed were synthesized, and in the third step, two different amino-functionalized monomers [aminoethylmethacrylate hydrochloride (AEMH) and vinylbenzylamine hydrochloride (VBAH)] were used to synthesi...

CO2 accumulation is inducing an effect of global warming. Adsorption using solid sorbents proving as effective strategy for capture and reuse. The aim this study was to develop amino-functionalized magnetic nanoparticles by depositing various amines through co-precipitation or impregnation-sonication. Structural characteristics were studied SEM, BET XRD analyses, evidencing coarse particles wit...

Considering many applications of functionalized metal oxide nanoparticles in magnetic resonance imaging, drug delivery, neutron irradiation, electronics, catalysis and optics; herein, a new strategy is developed to functionalize magnetite nanoparticles to improve their performances in the delivery of acyclovir. In this study, magnetite Fe3O4 nanoparticles are synthesized b...

   Amido-amino functionalized halloysite stabilized copper nanoparticles (aah-CuNPs) were synthesized through one-pot protocol by a wet chemical method using hydrazine as reducing agent. The nanocomposite formed was stable in dry ethanol. The composition and binding nature of the nanocomposite were studied using FT-IR, DRS-UV, EDAX and powder XRD techniques. The morphological features of th...

Abstract A boron trifluoride catalysed reaction of coplanar 9-(phenyl­ethynyl)-9H-fluoren-9-ols with various 2-aminobenzamides affords a number highly functionalized, conjugated (Z)-2-((2-(9H-fluoren-9-ylidene)-1-phenylethylidene)amino) benzamides in excellent yield. The the presence N-bromosuccinimide (E)-5-bromo-2-((2-bromo-2-(9H-fluoren-9-ylidene)-1-phenylethylidene)amino)benz­amides very go...

A facile solvothermal route has been developed for the preparation of europium doped gadolinium orthovanadate nanoparticles (~70 nm) with tetragonal structure, based on a homogenous precipitation reaction at 120 °C from rare earth precursors (yttrium nitrate and europium nitrate) and sodium orthovanadate solutions using an ethylene glycol-water mixture as the solvent. The effects of the doping ...

This study investigates the controlled chemical functionalization of silicon oxide nanostructures prepared by AFM-anodization lithography of alkyl-terminated silicon. Different conditions for the growth of covalently bound mono-, multi- or submonolayers of distinctively functional silane molecules on nanostructures have been identified by AFM-height investigations. Routes for the preparation of...
