In this paper we report synthesis of Fe2TiO5-5A zeolite (Z5A) nanocomposites with 5%, 10% and 20% weight percent of Fe2TiO5 in 5A zeolite in stearic acid media after calcination of the gel samples obtained at 600-900°C for 2 hrs. The powder X-RAY diffraction (XRD) patterns have been used for characterization of the prepared samples. The Scanning Electron Microscopy (SEM) images and X-ray Energy...

In this work, we report synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, cetyltrimethylammonium bromide CTAB as cationic surfactant and butanol as a cosurfactant. Silica surface modification of the as prepared nanoparticles was performed by adding tetraethoxysilane TEOS to alkaline medium. The struct...

Abstract Ferrofluids are a type of nanometer-scale functional material with fluidity and superparamagnetism. They composed ferromagnetic particles, surfactants, base liquids. The main characteristics ferrofluids include magnetization, the magnetoviscous effect, levitation characteristics. There many mature commercial ferrofluid damping applications based on these that widely used in numerous fi...

The magnetic field dependences of the magnetization (B≤9 T, T=2-70 K) samples from a single crystal Pb 1-y Sc y Te (y=0.01) ingot, synthesized by Bridgman method, are studied. It is established that, in accordance with generally accepted model rearrangement electronic structure alloys during doping, there no paramagnetic contribution scandium ions located nodes metal sublattice studied samples....

In this work, the link between photocatalytic performance of Co-Zn ferrite nanoparticles and net magnetic moment is analyzed. CoxZn1-xFe2O4 (0 ≤ x 1) were synthesized by co-precipitation method different physicochemical techniques employed to characterize samples (X-ray diffraction, Transmission Electron Microscopy (TEM), BET surface area, Diffuse Reflectance Spectroscopy (DRS), Photoluminescen...

As a novel functional nanomaterial, Fe3O4 magnetic nanoparticles (MNPs) modified by different surfactants have attracted and are attracting worldwide interest. In this research, we introduced two silane coupling agents to modify MNPs instead of single surfactant achieve complete coating functionalization. The modification mechanism was also explained. Techniques such as TEM, XRD, FT-IR, TG-DSC,...
