Fabrication and characterization of Fe3O4/perlite, Fe3O4/perlite@SiO2, and Fe3O4/perlite@SiO2@sulfanilamide magnetic nanomaterials

Applied Physics A, 2022
Abstract In this study, the fabrication of perlite-supported Fe3O4 (Fe3O4/perlite), SiO2-coated Fe3O4/perlite (Fe3O4/perlite@SiO2), and sulfanilamide-modified Fe3O4/perlite@SiO2 (Fe3O4/perlite@SiO2@sulfanilamide) magnetic nanomaterials and their characterization by various spectroscopic techniques were presented.

Magnetoresistance of Fe3O4/Au/Fe3O4 and Fe3O4/Au/Fe spin-valve structures

Journal of Magnetism and Magnetic Materials, 2004
Abstract A detailed study of the in-plane magnetotransport properties of spin valves with one and two Fe 3 O 4 electrodes is presented. Fe 3 O 4 /Au/Fe 3 O 4 spin valves exhibit a clear anisotropic magnetoresistance in small magnetic fields but no giant magnetoresistance (GMR).

Characterization for strontium titinate/Fe3O4 and TiN/Fe3O4 interfaces

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2002
The interface formation between different thicknesses of strontium titanate (SrTiO3) or titanium nitride (TiN) with a 2000 Å Fe3O4 film is studied using x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD). Our results show that the deposition of 10–50 Å of TiN results in an immediate and substantial removal of oxygen from ...

Electrochemical-enhanced MoS2/Fe3O4 peroxymonosulfate (E/ MoS2/Fe3O4/PMS) for degradation of sulfamerazine

Chemosphere, 2022
Seeking effective methods to degrade organic pollutants has always been a hot research field. In this work, MoS2/Fe3O4 catalyst was synthesized by hydrothermal method with MoS2 as carrier to construct an advanced oxidation system of electrochemical enhanced MoS2/Fe3O4-activated peroxymonosulfate (E/MoS2/Fe3O4/PMS). The materials were characterized by X-

Magnetoresistance effect in Ag–Fe3O4 and Al–Fe3O4 composite films

Journal of Applied Physics, 2003
The Agx–(Fe3O4)1−x and Agx–(Fe3O4)1−x composite films were prepared by dc sputtering on Si(100) substrates. The x-ray diffraction results show that the films contain essentially only the cubic inverse spinal phase from Fe3O4 and face-centered cubic phase from Ag or Al.

Polysorbate Stabilised Fe3O4 and Fe3O4@Au Nanoparticle Synthesis and Characterisation

Materials Today: Proceedings, 2015
Polysorbate (tween) stabilised iron oxide and gold coated iron oxide nanoparticles were synthesised using the high-temperature solution phase reaction of iron(III) acetylacetate, Fe(acac)3, with 1,2-hexadecanediol and long chain alcohols. FT-IR analysis confirmed the presence of the surfactants on the nanoparticles, while the size and shape of the ...

PLLA- Fe3O4 nanocomposites

AIP Conference Proceedings, 2012
In the present work magnetite nanoparticules and PLLA- Fe3O4 nanocomposites were prepared by high frequency ultrasound. The influence of pH on nanoparticle size was studied, showing that the particle size decreased as the pH increased. In the composites an interaction between the magnetite nanoparticles and the PLLA matrix was observed by FTIR ...

Fe3O4·C and ZrO2·Fe3O4·C nanostructures: Synthesis and characterization

Russian Journal of General Chemistry, 2015
A procedure for the synthesis of carbon-encapsulated multilayer magnetite and zirconium oxide–magnetite nanoparticles that form porous nanostructures, for use as biocompatible sorbents, is proposed. The properties, composition, dimensions, particle shapes, surface morphology, and magnetic characteristics of the products are studied.
