Self-consistent Hydrodynamic Model of Electron Vortex Fluid in Metals

Authors: Victor L. Mironov
Comments: 11 Pages.

We propose a system of self-consistent equations for electron fluid in metal, which describes vortex flows and frozen-in internal electromagnetic field. It is shown that in case of ideal fluid the proposed model describes the electrodynamics of superconductor, and in vortex-less case it leads to the well known London equations. However, the speed of fluctuations propagation is equal to the speed of electron sound, and not the speed of light, which is more adequate from a physical point of view. The normal metal is described by similar equations, but taking into account damping processes. The main peculiarities of the proposed equations are illustrated with the analysis of electron sound waves.

The Influence of Ultra-dispersion Particles on Electron Density in SOFC Materials.

Authors: N. M. Kirjukhin, J. N. Kleschev, A. V. Sagalovich, V. V. Sagalovich
Comments: 7 Pages.

Further progress in industrial electrochemical generators' designs utilising SOFC considerably depends on problem of obtaining fuel cell materials with predefined properties [1,2]. Due to this fact, considerable efforts of designers are directed on creation of optimum composition «anode-electrolyte-cathode», and on microconstruction of SOFC materials (selection of phase and element composition, defect structure formation, etc.). In the second problem nanocomposite systems having unique properties are of greatest interest [3]. Utilising of such materials as solid electrolyte may allow significantly improve cell's parameters, in particular, increase ionic conductivity [4,5].However mechanisms leading to this effect were not determined singly. In this article the influence of nanoparticles ensemble with work of exit that different from the rest of the matrixon the change of electron density in SOFC materials have been examined theoretically. The calculations of concentration distribution of free carriers around single particle and for microparticles ensemble were fulfilled. Inconclusion possible directions of forming of nanostructures conformably to SOFC materials discussed.

Nanocomposites and Semiconductor Devices Based on Recycled Radioactive Waste

Authors: Valeriy Kizka
Comments: 8 Pages. doi:10.20944/preprints202207.0188.v1

The article provides an overview of nanocomposites and microelectronic elements used in space electronics and radiation control systems of nuclear reactors. Only those nanocomposites and microelectronic elements are taken into account that improve their characteristics in radiation fields or remain indifferent when exposed to ionizing radiation. Considering the chemical composition of the materials of these nanocomposites and microelectronic elements, it is analyzed from which radioactive materials (RM) obtained by recycling radioactive waste (RW) such composites and microelectronic parts can be made. Thus, an alternative way of radioactive waste disposal is proposed, when these wastes are used in the form of microelectronic elements designed to operate under conditions of cosmic radiation.

Deposition of the Stoichiometric Coatings by Reactive Magnetron Sputtering

Authors: A. Sagalovich, S. Dudnik, V. Sagalovych
Comments: 10 Pages.

The investigations of the reactive magnetron depositing of the stoichiometric coatings "metal-metalloid" were done. The dependences between sputtering parameters of a target and processes of plasmo-chemical formation on the surface of sample "metal-metalloid" and formations of coatings of the appropriate structure were investigated. Experimental data on stoichiometric coatings AlN, Al2 O3 , TiN, TiO2 is given. Features of reactive magnetron deposition and investigation results for obtaining of coatings with pregiven properties in particular for providing stability and controllability of coating deposition processes in time.

Intrinsic Correlation Between Superconductivity and Magnetism

Authors: Xiuqing Huang
Comments: This is a condensed version consisting of 4 pages and 5 figures.

Based on the real-space Mott insulator model, we establish a unifiedpairing, coherent and condensate mechanism of superconductivity. Motivatedby Dirac's magnetic monopole and Maxwell's displacement current hypothesis,we demonstrate that electric and magnetic fields are intrinsicallyrelevant. An isolated proton or electron creates an electric field,whereas a quantized proton-electron pair creates a magnetic field.The electric dipole vector of the proton-electron pair is the Ginzburg-Landauorder parameter in the superconducting phase transition. The Pierce-likedimerization pairing transition of the electron-proton electric dipolelattice leads to the symmetry breaking of the Mott insulating stateand the emergence of superconducting and magnetic states. This theoreticalframework can comprehensively explain all superconducting phenomena.Our research sheds new light on electron spin, magnetic monopoles,and the symmetry of Maxwell's equations.
