In the current paper,Nanostructured Nickel oxide (NiO) were synthesized by co-precipitation method using Nickel(II) Chloride Hexahydrate (NiCl2.6H2O) and sodium hydroxide (NaOH) as starting material. Structural, optical and magnetic properties of nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Atomic force microscope (AFM), UV–Vis absorption; Fo...

In this work, WO3 nanoparticle decorated magnetic poliamidoamin (PAMAM) dendrimer nanocomposites were fabricated and used as a catalyser for the reduction of 4-nitrophenol (4-NP). Fe3O4 superparamagnetic iron oxide nanoparticles core. Magnetic produced using hydrothermal synthesis. core was covered with PAMAM dendrimers. The dendrimers in covering process 2nd generation which proposed to protec...

The new heterogeneous catalyst based on MoO2(acac)2 immobilized on superparamagnetic nanoparticle functionalized with dendrimer was synthesized. The dendrimer with amine and sulfur functional groups offer proper positions for a strong connection between MoO2(acac)2 and support. The synthesized catalyst was characterized by FT-IR spectroscopy, ICP, TGA, SEM, TEM, and XRD. This catalyst showed hi...

N-sodium acrylate-O-carboxymethyl chitosan [CMCH-g-PAA(Na)] bound Fe3O4 nanoparticles were developed as a novel magnetic nanoparticles with an ionic structure that can be potentially used in many fields. CMCH-g-PAA (Na) was obtained by grafting of sodium polyacrylate on O-carboxymethyl chitosan, which is an amphiphilic polyelectrolyte with the biocompatibility and biodegra...

With an increasing rate of cancers, the need for effective cancer management has led to the development of theranostic systems for cancer diagnosis and therapy. Conventional techniques for cancer management, however, have limited success due to inaccurate diagnosis and systemic toxicity of therapeutic reagents. Using novel biodegradable photoluminescent polymers developed in our group and super...

PURPOSE To develop the hypothesis that magnetic nanoparticles, found in many organisms and often involved in biological reactions to weak electromagnetic fields (EMF), mediate EMF-induced DNA damage which could result in increased risk of childhood leukaemia and other cancers. MATERIALS AND METHODS An analysis of current research into magnetic nanoparticles. Physics estimates and the developm...

Tailoring the structure of nanocrystal superlattices is an important step toward controlled design of novel nanostructured materials and devices. We demonstrate how the long-range order and macroscopic dimensions of magnetic nanoparticle arrays can be controlled by the use of a modulated magnetic field. Inducing a dipolar attraction during the initial stage of the drying-mediated self-assembly ...
