Abstract With the development of type II high temperature superconducting (HTS) ReBCO tape, it has been widely used in field magnets. Conductor on round core (CORC) cable is highly flexible and fully isotropic, making one most important types HTS cables. In condition current, electromagnetic mechanical behaviors CORC under screening current effect are not clear. this paper, studied for first time by combining simulation. A three-dimensional shell model a solid element single-layer...

The introduction of dynamic covalent bonds into shape memory polymers (SMPs) has offered the possibility reprocessing, but multifunctional modifications have not been sufficiently investigated. This work reported photoluminescence thermadapt two-way SMPs (2W-SMPs) based on syndiotactic 1,2-polybutadiene (SPB). ZnS:Cu particles were modified to form β-hydroxyester with epoxidized SPB (ESPB), and a reversible cross-linked network was constructed inside polymer. crystallization–melting...

A spin Hall effect (SHE) enables the electrical generation and detection of currents for promising applications in spintronics, but heavy metals with low angle θSH limit development SHE devices. In this work, we have introduced dielectric oxide material SrTiO3 into Pt by magnetron sputtering measured on NiCo/Pt1–x(STO)x heterostructure through spin-torque ferromagnetic resonance. Our results demonstrate that maximum Pt0.98(STO)0.02 is 0.121 ± 0.003, which approximately twice pure (0.064...

Abstract The abnormal temperature rise and early quench often happened to the high field superconducting magnet, especially when magnetic is higher than 20 T. This phenomenon attributed helium gas bubbles levitation in special environment. So, it very important accurately identify formation distribution of for development magnet. In this paper, a new analytical method based on pressure proposed analysis conditions spatial levitation. And no-insulation REBCO insert coil was also developed...

Fusion devices are developing rapidly in recent years and designed to generate over 20 T magnetic field the future devices. Diverse high temperature superconducting (HTS) conductors for fusion have been widely studied laboratories around world. Bi-2223 tapes better mechanical thermal stability compared with REBCO tapes, is more suitable manufacturing complicated magnets. Based on a HTS cable-in-conduit conductor (CICC) coil this study. Its structure design electromagnetic analysis...

Abstract Flue gas desulfurization facilities produce flue ash (FGDA), which has ecological and economic benefits. In this article, we explored the possibility impact of using FGDA as sole reinforcing filler to mechanically improve epoxidized natural rubber (ENR). The influence on properties composites was examined. exhibits good interfacial interaction compatibility with ENR, improves mechanical ENR. When 15 phr added, tensile strength increased by approximately 41.4% compared that pure This...

Bi-2223/Ag high-temperature superconducting (HTS) tapes have been widely used in magnet. For fusion magnets, transverse loads are introduced HTS tapes, caused by mechanical, thermal and electromagnetic stress during manufacturing, winding operation which leads to a remarkable degradation of critical current (Ic), thus cause the performance In this study, <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">I</i> <sub...

Through studying the Ternary FPRM expression and polarity conversion algorithm, combining with mayfly optimization this paper proposes a decomposition-based multi-objective (Multi objective algorithm based on decomposition, DMMA) solution. The DMMA decomposes target space into multiple uniform subspaces, each subspace independently retains Pareto solution so as to improve distribution of population front; using Chebyshev decomposition method, optimal sub-problem is taken direction evolution...
