Applying wide-angle X-ray scattering method, thermomechanical analysis, and differential scanning calorimetry, the structural organization and properties of nanocomposites formed by chemical reduction of Сu(2+) cations in the interpolyelectrolyte-metal complex (pectin-Cu(2+)-polyethyleneimine) under the influence of a constant magnetic and electric fields have been studied. It has been found th...

The interaction of electromagnetic radiation with a magnetic nanocomposite based on carbon nanotubes (CNT) is considered within the model of distributed random nanoparticles with a core-shell morphology. The approach is based on a system composed of a CNT conducting resistive matrix, ferromagnetic inductive nanoparticles and the capacitive interface between the CNT matrix and the nanoparticles,...

In the present investigation, ZnFe2O4@MnO and MnFe2O4@ZnO magnetic nanocomposites were fabricated via a facile hydrothermal method and were calcined at 300 °C for 3 h. Synthesis of ZnFe2O4@MnO and MnFe2O4@ZnO magnetic nanocomposites optimized by the different weight percentages. The synthesized photocatalyst...

A magnetoresistive tactile sensor is reported, which is capable of working in high temperatures up to 140 °C. Hair-like bioinspired structures, known as cilia, made out of permanent magnetic nanocomposite material on top of spin-valve giant magnetoresistive (GMR) sensors are used for tactile sensing at high temperatures. The magnetic nanocomposite, consisting of iron nanowires incorporated into...

Nanocomposite of CoFe2O4/SrFe12O19 has been synthesized by the electrospinning and calcination process. A novel method that cobalt powder was used to replace traditional cobalt salt in the precursor sol-gel for electrospinning was proposed. The crystal structures, morphologies, and magnetic properties of these samples have been characterized in detail. Moreover, when the average crystallite siz...

CoFe2O4 Magnetic Nano Particles (MNPs) were synthesized by an efficient method in aqueous medium with the particle sizes of about 20-50 nm. Then, a hybrid nanocomposite of polyaniline (PANI)-CoFe2O4 MNPs has been electrodeposited directly on a stainless steel wire by the potentiostatic method. Microscopic images of electrodeposited PANI and PANI-C...

Nanocomposite high resistive soft magnetic materials Fe/SiO2 ~Fe volume fraction 50%! have been synthesized using a wet chemical reaction method. A series of metal-ceramic Fe/SiO2 nanocomposite powder samples were obtained by annealing the precursor at temperatures from 400 to 900 °C in the presence of a reducing agent. The compositions of the precursor and the successive heat-treated samples h...
