The adsorption of the antibiotic ciprofloxacin (CIP) from an aqueous solution by natural zeolite, calcium-rich clinoptilolite (CLI), and magnetite-coated CLI (MAG-CLI) was investigated. Both MAG-CLI showed a high affinity towards CIP at 283, 288 293 K pH 5. Adsorption kinetics studied for initial concentrations 15–75 mg dm?3 follow Lagergren’s pseudo-second order equation is best represented La...

Dalam artikel ini digambarkan hematite nano partikel (lebih kecil dari 100 nm) telah berhasil disintesis dengan metode Sol-Gel menggunakan Ferri nitrat (Fe(NO 3 ) .9H 2 O) dan Ethylene glycol (C H 6 O sebagai prekursor pada temperature anil yang berbeda yaitu 200, 300 400 0 C. Nanopartikel magnetite diperoleh ditandai alat X-Ray difraksi (XRD), Scanning Electron Microscope (SEM), energi X-ray s...

In the present work, PVDF - Fe3O4 nanoparticle (NP) nanocomposite films were produced using electrospinning method. We investigated effect of NP size on film's morphology (fiber size), mechanical properties, and physical properties (β-phase percentage). Surprisingly, while acts as an enhancer for it appeared to act inhibitor in terms its effects crystallization β-polymorph. This result seemed d...

Introduction In this study, we describe the results of controlled synthesis and application of gold coated Fe3O4/SiO2 nano-shells combined with the optical property of gold for enhancement of selective photothermal interaction with cancerous cells based on the surface plasmon resonance (SPR) Phenomena. Materials and Methods Magnetite Nano-Particles (MNPs) were prepared by means of co-precipitat...

In this study, Cu-Ni-Fe-Cr layered double hydroxide (LDH) immobilized on silica magnetite (Fe3O4@SiO2@Cu-Ni-Fe-Cr LDH) was investigated towards ring opening of diverse epoxides with acetic anhydride to afford vic-diacetates within 15–40 min in high yields. Reusability the nano-LDH also studied for 6 consecutive cycles without significant loss catalytic activity.

This work describes the thermal stability and magnetic properties of polyvinylidene fluoride (PVDF)/magnetite nanocomposites fabricated using the solution mixing technique. The image of transmission electron microscopy for PVDF/magnetite nanocomposites reveals that the 13 nm magnetite nanoparticles are well distributed in PVDF matrix. The electroactive β-phase and piezoelectric responses of PVD...
