Abstract Employing nanofiber framework for in situ polymerized solid‐state lithium metal batteries (SSLMBs) is impeded by the insufficient Li + transport properties and severe dendritic growth. Both critical issues originate from shortage of conduction highways nonuniform flux, as randomly‐scattered backbone highly prone to slippage during battery assembly. Herein, a robust fabric 0.33 La 0.56 Ce 0.06 Ti 0.94 O 3‐δ /polyacrylonitrile (p‐LLCTO/PAN) with inbuilt channels high interfacial flux...

Summary In this study, non‐starch polysaccharides (NSPs), namely konjac glucomannan (KGM), inulin (IN), and oat β ‐glucan (OG), were selected as ingredients to inhibit the retrogradation of fresh instant rice. Through a comprehensive comparison, it was found that addition 0.4% KGM, 0.6% IN, 1.5% OG (w/w, based on rice mass) gave favourable eating quality. Furthermore, storage time increased, adding these NSPs mitigated increase in hardness, enthalpy (), free water, indicating their ability...

Using 14M $\psi(2S)$ events accumulated by BESII at the BEPC, a Covariant Helicity Amplitude Analysis is performed for $\psi(2S)\to\pi^+\pi^-J/\psi, J/\psi\to \mu^+\mu^-$. The $\pi^+\pi^-$ mass spectrum, distinctly different from phase space, suggests $\sigma$ production in this process. Two theoretical schemes are used global fit to data. results consistent with existence of $\sigma$. pole position determined be $(552^{+84}_{-106})-i(232^{+81}_{-72})$ MeV/$c^2$.
