This paper describes that the ferromagnetic resonance (FMR) frequency shift can be calculated by an electromagnetic field simulator based on the Maxwell's equation although the relative permeability and the FMR frequency is defined by the Landau-Lifshitz-Gilbert (LLG) and the Kittel's equation. We evaluate the magneti…
Patchy colloids are promising candidates for building blocks in directed self-assembly. To be successful the surface patterns need to both be simple enough to be synthesized, while feature-rich enough to cause the colloids to self-assemble into desired structures. Achieving this is a challenge for traditional synthesi…
The paper is focused on a toroidal superconducting transformer with cold magnetic core. The transformer was developed aiming at the solution where magnetic core could operate immersed in LN2, not having much higher power losses than a core operating in room temperature. The second aim is concerned to the perpendicular…
In the present work 1D Zinc Oxide nanostructures were synthesized sucesfuly by local heating method at various concentration and temperature. Crystaline nature of ZnO nanostructures was confirmed by the apearance of high intensity peak at (0 0 2) in X-ray difraction analysis of diferent samples. FESEM analysis confirm…
The nature, behavior and position of a longitudinal crack in a homogeneous slab is investigated using FVM (Finite Volume Method). Effect of the crack on the stationary temperature field around the slab is also investigated. The slab is presumed to have a source subjected to high temperature and the crack surface is sp…
Abstract The manufacturing of wood–polymer composites (WPCs) by compounding wood particles with plastic at temperatures above their melting point may cause thermal degradation of the wood, which can lead to undesirable properties, including odor, discoloration, and degradation of the mechanical properties of the panel…
The novel strategies are applied for synthesis of silver nanoparticles (AgNP) using biological methods, since AgNP has various applications including high anti-microbial activity. The biological method using plant extracts is relatively unexplored. Nanoparticles formed from plants are more stable and bio-compatible. F…
In the development of high-Tc superconducting(HTS) devices, the bushing for HTS devices (HTS bushing) is the core technology, the need to because of supply high voltage to the cable or the winding of the transformer. The lower part of the bushing is exposed to the liquid nitrogen (LN 2 ), and it has many sheds. In par…
The cathodoluminescence and photoluminescence (PL) spectra of ZnO nanoparticles (NPs) embedded into the cetylpyridinium chloride (CPCL) matrix were studied. The composites were obtained by drying an aqueous suspension of CPCL and ZnO NPs, with NaCl and with NaOH additives. We observed that only NaOH addition lead to a…
The measurements of YBa2Cu3O7-X films magnetization are made at ramp rate of the external magnetic field up to 105 T/sec at temperature of liquid nitrogen in fields up to 4 T. The linear dependence of the magnetic moment of films on rate of an external magnetic confirms, that in the large electrical fields down to 1 V…
The stability and durability of trapped flux is a focus in investigations of melt-growth (RE)Ba2Cu3O7−δ (RE=rare earth, e.g., Y, Gd, Sm) bulk high-temperature superconductors. In magnetic flux engineering applications, two important issues affect the expected performance of bulk superconductors: flux trapping and flux…
HTSC 2G YBCO based short samples were formed by PLD (pulsed laser deposition) on the cube textured Ni-W tapes. The influence of buffer layer architecture on the critical properties of HTS films was investigated with scanning and transmission electron microscopy, X-ray diffraction and four point probe electrical measur…
This paper presents the design and theoretical characterization of a composite uniform-gradient planar waveguide polarimetric interferometer. Presented structure is composed of an Ag+↔Na+ ion-exchange based waveguide formed in Borosilicate 33 glass substrate and a uniform, sol-gel based, silica-titania film. Character…
Bi 2 Sr 2 CaCu 2 O 8 thin films have been deposited on MgO single crystal substrates by spin-coating a solution based on 2-ethylhexanoate precursors dissolved in xylene. Pyrolysis takes place between 200°C and 450°C and is accompanied by the release of 2-ethylhexanoic acid, CO 2 and H 2 O vapour. Highly c-axis oriente…
Varying the thickness of the Pd layer, the role of the Pd films deposited on the cube-textured Ni-based substrates, was assessed in order to investigate the issues related to substrate oxidation phenomena and their impact on the quality of the buffer layer structures. Using a low temperature annealing, 600 °C, a thres…
We study the Josephson effect in S ± IS ± junctions made by a two band superconductor with s ± wave symmetry. We derive the Andreev coefficients for the scattering problem at the junction interface and the temperature dependence of the critical current. We predict various features of the Josephson current for certain…
Comparative assessment of the effect the yield strength has on the characteristics of EI-415 steel under creep conditions is carried out based on the results from long-term (for more than 70000 h) tests of notched samples at an elevated temperature. The metal of three rotors (EI-415 steel) (one after it had been in op…
A detailed characterization of the voltage-noise properties has been performed in FeTe 0.5 Se 0.5 epitaxial thin films and Co-doped BaFe 2 As 2 bilayers, deposited by pulsed laser deposition. In all the samples analyzed, the experimental voltage-spectral density has a 1/f noise component. Different behaviors are obser…
Femtosecond spectroscopy has been used to investigate the quasi-particle relaxation times in nearly optimally doped Fe-based superconductors FeSe 0.5 Te 0.5 and optimally doped Ba-122 thin films growth on a Fe buffer layer. Experimental results concerning the temperature dependence of the relaxation time of such pnict…
