El desarrollo de nuevos sensibilizadores para la degradación fotoquímica contaminantes ha sido un foco atención en los últimos años, es por ello que nanomateriales han tomado una gran relevancia este campo. En contexto, se trabajó síntesis nuevo nanomaterial óxido hierro (Fe3O4) y plata (Ag), el cual fue obtenido dos etapas; primer lugar sintetizaron las nanopartículas magnetita (NPs) luego ads...

A greener approach to synthesize the chitosan (Cs) supported palladium (Pd) magnetic (Fe3O4) nanoparticles (NPs) using Epiphyllum oxypetalum (Eo) leaf extract under ultrasound-assisted extraction was carried out. The reduction of Pd (II) (0) accomplished by phytochemical present in whereas used as core wall material. presences phytochemicals were confirmed liquid chromatography with mass spectr...

: Fluids containing nanometer-sized particles (nanofluids, NFs) are potential candidates to improve the performance and efficiency of several thermal devices at micro- macro-scale levels. However, problem sedimentation instability these colloidal dispersions has been biggest obstacle for industrial-scale applications. In this work, two different NFs were tested using distilled water (DI-Water) ...

Cinnamaldehyde, the bioactive component of the spice cinnamon, and its derivatives have been shown to possess anti-cancer activity against various cancer cell lines. However, its hydrophobic nature invites attention for efficient drug delivery systems that would enhance the bioavailability of cinnamaldehyde without affecting its bioactivity. Here, we report the synthesis of stable aqueous suspe...

A novel type of flexible [Fe3O4/PANI/PMMA]@{[Eu(BA)3phen + Tb(BA)3phen]/PMMA} (PMMA = polymethyl methacrylate, BA = benzoic acid, phen = phenanthroline, PANI = polyaniline) belt-shaped coaxial microcable possessing electrical conductivity, magnetism and color-tunable photoluminescence has been successfully fabricated by electrospinning technology using a specially designed coaxial spinneret. Ev...

In this study, 18-38 nm-sized and spherical-shaped nanopowder Fe3O4 NPs concentrations (0.4, 2, 10, 50, 250 µg/10 µl) was force-fed to sixth instar (180 ± 20 mg) Galleria mellonella (Lepidoptera: Pyralidae) larvae under laboratory conditions. The effects of magnetic iron oxide nanoparticles (Fe3O4) on the pupal adult developmental times, weights longevity G. were recorded. Results showed that t...

this paper describes the development of a procedure for pb(ii) ions removal from various water samples after magnetic solid phase extraction (mnps) by magnetite nanoparticles (fe3o4 nps) modified with sodium dodecyl sulfate (sds) and pyrrolidine-1-dithiocarboxylic acid ammonium (pdtcaa). the synthesis of fe3o4 nps was certified by characterization techniques including field emission scanning el...

Goal: The potent anti-cancer activity of Arteether (ARE) has been the focus of many studies. However, the hydrophobic property of this drug limits its application. To increase the bioavailability of ARE, we formulated a nanosystem (NS) of folic acid (FA), chitosan (CS) and Fe3O4 for delivery of ARE against breast cancer. Material and Methods: The CS coated Fe3O4 was synthesized by co-precipitat...

Herein, we report preparation of magnetic hybrid nanoflower (MhNF) formed horseradish peroxidase (HRP), copper ions (Cu2+) and iron oxide nanoparticles (Fe3O4 NPs) with greatly enhanced activity, stability, reusability applicability for use in removal phenol from aqueous solution. In this study, pre-synthesized small sized Fe3O4 NPs were immobilized to synthesized HRP-Cu2+ (hNFs). The MhNFs cha...
