Localization and transfer of charge carriers in CuO nanopowder by impedance spectroscopy
Abstract Particular electro-physical characteristics of CuO nanopowder were investigated by impedance spectroscopy using a sensor based on interdigitated structure in the frequency range from 1 Hz to 100 MHz. The results ...
Production of high-coercivity materials based on BaFe12O19 by crystallization of plasma-sputtered powders
Abstract Ferrite powders BaFe12O19 were studied in the present work after plasma heating and rapid quenching in differentenvironment: in air, in water and on the copper disk. X-ray diffraction analysis (XRD), scanning ...
Device for Increasing the Magnetic Flux Pinning in Granular Nanocomposites Based on the High-Temperature Superconducting Ceramic
A device for modifying the granular high-temperature superconducting ceramics in the plasma of a low-pressure arc discharge has been considered. The particular features of the design and operational principle of this device ...
Study of Phase Composition of CuO/Cu2O Nanoparticles Produced in the Plasma of a Low-Pressure Arc Discharge
The influence of synthesis parameters on peculiar features of the forming crystalline phases of copper oxide nanoparticles is inspected via electron microscopy, IR spectroscopy, X-ray diffraction, and differential thermal ...
The Structural State of Ultrahigh-Molecular-Weight Polyethylene in Single-Stage Arc-Discharge Plasma Deposition of Nanoparticles
Abstract—We present the results of a study of the structural state of ultrahigh-molecular-weight polyethylene (morphology, X-ray-diffraction patterns, IR spectra) obtained in a single technological cycle combining the synthesis ...
Peculiarities of magnetic behavior of CuO nanoparticles produced by plasma-arc synthesis in a wide temperature range
Abstract Copper oxide nanoparticles, produced by direct plasmochemical synthesis in a low-pressure arc discharge plasma, show a wide variety of magnetic properties depending on the strength of the external magnetic field ...
