Abstract An ultrathin solid polymer electrolyte (SPE) consisting of modified polyethylene (PE) as the host and poly(ethylene glycol) methyl ether acrylate lithium salts fillers is presented. The porous poly(methyl methacrylate)–polystyrene interface layers closely attached on both sides PE effectively improve compatibility among electrolytes electrodes. resultant 10 μm‐thick SPEs possess an ultrahigh ionic conductance 34.84 mS at room temperature excellent mechanical properties 103.0 MPa...
An ingenious interface re-engineering strategy was applied to in situ prepare a manipulated LiH2PO4 protective layer on the surface of Li anode for circumventing intrinsic chemical stability issues Li10GeP2S12 (LGPS) metal, specifically migration mixed ionic-electronic reactants inner LGPS, and kinetically sluggish reactions interface.

Reliable and reproducible resistive switching behaviors were observed in graphene oxide (GO) thin films prepared by the vacuum filtration method. The Cu/GO/Pt structure showed an on/off ratio of about 20, a retention time more than 104 s, threshold voltages less 1 V. effect could be understood considering desorption/absorption oxygen-related groups on GO sheets as well diffusion top electrodes. Our experiments indicate that is potentially useful for future nonvolatile memory applications.
An exact quantum master equation formalism is constructed for the efficient evaluation of non-Markovian dissipation beyond weak system-bath interaction regime in presence time-dependent external field. A novel truncation scheme further proposed and compared with other approaches to close resulting hierarchically coupled equations motion. The interplay between strength, property, required level hierarchy also demonstrated aid simple spin-boson systems.

We report two nondegenerate magnon modes with opposite spins or chiralities in collinearly antiferromagnetic insulators driven by symmetry-governed anisotropic exchange couplings. The consequent giant spin splitting contributes to Seebeck and Nernst effects generating longitudinal transverse currents when the temperature gradient applies along away from main crystal axis, without requiring any external magnetic field spin-orbit coupling. Based on first-principle calculations, we predict...
