Abstract	The active cyano-group in polyacrylonitrile has severe passivation of lithium anode under larger current density, which restricts the wide application of polyacrylonitrile(PAN) in lithium metal batteries. Herein, in order to address the excessive passivation of lithium metal by PAN, inspired by the pre-oxidation of carbon fibers, PAN was pre-oxidized at 230 °C, which transformed part of the cyano group into a more chemically stable cyclized structure. The electrochemical and mechanical properties of the composite solid electrolyte were effectively improved by introducing the fast ionic conductor Li

Abstract	The garnet ceramic Li₆.₄La₃Zr₁.₄Ta₀.₆O₁₂ (LLZTO) modified separators have been proposed to overcome the poor thermal stability and wettability of commercial polyolefin separators. However, the side reaction of LLZTO in the air leads to deterioration of environmental stability of composite separators (PP-LLZTO), which will limit the electrochemical performance of batteries. Herein, the LLZTO with the polydopamine (PDA) coating (LLZTO@PDA) was prepared by solution oxidation, and then applied it to a commercial polyolefin separator to achieve a composite separator (PP-LLZTO@PDA). LLZTO@PDA is stable in the air, and no Li₂CO₃ can be observed on the surface even after 90 days in the air. Besides, LLZTO@PDA coating endows the PP-LLZTO@PDA separator with the tensile strength (up to 103 MPa), good wettability (contact angle 0°) and high ionic conductivity (0.93 mS cm⁻¹). Consequently, the Li/PP-LLZTO@PDA/Li symmetric cell cycles stably for 600 h without significant dendrites generation, and the assembled Li//LFP cells with PP-LLZTO@PDA-D30 separators deliver a high capacity retention of 91.8% after 200 cycles at 0.1C. This research provides a practical strategy for constructing composite separators with excellent environmental stability and high electrochemical properties.

Abstract	Polymer electrolytes (PEs) with high flexibility, low cost, and excellent interface compatibility have been considered as an ideal substitute for traditional liquid electrolytes for high safety lithium metal batteries (LMBs). Nevertheless, the mechanical strength of PEs is generally poor to prevent the growth of lithium dendrites during the charge/discharge process, which seriously restricts their wide practical applications. Herein, a mechanical robust ZIF-8/epoxy composite electrolyte with unique pore structure was prepared, which effectively inhibited the growth of lithium dendrites. Meanwhile, the in situ growth of ZIF-8 in porous epoxy matrix can promote the uniform flux and fast transport of lithium ions. Ultimately, the optimal electrolyte shows high ionic conductivity (2.2 × 10

Abstract	Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with periodic networks that are constructed from small molecular units via covalent bonds, which have low densities, high porosity, large specific surface area, and ease of functionalization. The one-dimension nanochannels in COFs offer an effective means of transporting lithium ions while maintaining a stable structure over a wide range of temperatures. As a new category of ionic conductors, COFs exhibit unparalleled application potential in solid-state electrolytes. Here, we provide a comprehensive summary of recent applications and research progress for COFs in solid-state electrolytes of lithium metal batteries and discuss the possible development directions in the future. This review is expected to provide theoretical guidance for the design of high-performance solid-state electrolytes.

Abstract	Linear polymer (e.g. polyethylene oxide, PEO) based electrolytes have been widely studied due to their flexibility and relatively good contact against electrodes. However, the linear polymers are prone to crystallization at room temperature and melting at moderate temperature, restricting their application in lithium metal batteries. To address these problems, a self-catalyzed crosslinked polymer electrolyte (CPE) was designed and prepared by the reaction of poly (ethylene glycol diglycidyl ether) (PEGDGE) and polyoxypropylenediamine (PPO) with only the bistrifluoromethanesulfonimide lithium salt (LiTFSI) added and with no any initiators. LiTFSI catalyzed the reaction by reducing the activation energy to form a crosslinked network structure, which was identified by calculation, NMR and FTIR. The as-prepared CPE has high resilience and a low glass transition temperature (Tg = -60 °C). Meanwhile, the solvent-free in-situ polymerization technique has been adopted in the assembly of the CPE with electrodes to decrease the interfacial impedance greatly and improve the ionic conductivity to 2.05 × 10

Abstract	Cardiac aging is manifested as unfavorable geometric and functional alterations in heart. The current work was to test whether a ketogenic diet (KD) impacted aging-associated myocardial remodeling and dysfunction in mice and investigate the underlying mechanism. The young and aged male mice were fed with KD or standard chow for four months. Echocardiography results revealed that KD decreased left ventricular end systolic diameter (LVESD) and increased fractional shortening in aged mice. With KD feeding, aged mice exhibited reduced cardiomyocyte cross-sectional area, fibrosis, and mRNA expression of atrial natriuretic peptide (ANP), Col1A1 and alpha smooth muscle actin (α-SMA) in myocardium. KD enhanced activities of superoxide dismutase 2 (SOD2), glutathione peroxidase (GPx) and catalase, and reduced the levels of malondialdehyde (MDA) and 3-nitrotyrosine (3-NT) in myocardium of aged mice. KD led to a downregulation of expression of C/EBP homologous protein (CHOP), glucose regulated protein 78 (GRP78), cleaved activated transcription factor 6 (ATF6), and spliced X box-binding protein 1 (XBP-1 s) in myocardium of aged mice. KD in aged mice reduced mitochondrial reactive oxygen species (ROS) formation, enhanced mitochondrial ATP production and mitochondrial membrane potential (MMP), and preserved activity of complex III and electron-coupling capacities between complexes I and III and between complexes II and III in myocardium. Importantly, KD in aged mice promoted autophagic flux, evidenced by reduced protein expression of p62 and enhanced protein expression of lysosome-associated membrane protein-2 (Lamp2) in myocardium. In conclusion, long-time KD intake delayed cardiac aging in male mice, possibly through abating oxidative stress, improving mitochondrial function, and promoting autophagic flux.

Abstract	Gualou Xiebai Decoction (GXD), a classic prescription, is widely used to dealing with inflammatory diseases in China for thousands of years. Abnormal metabolic state of bile acids (BAs) is confirmed to cause intestinal epithelial barrier dysfunction. In preliminary work, we observed that GXD could decrease intestinal permeability in hyperlipidemia mice. The present study aimed to explore the protective effect of GXD on intestinal mucosa in vitro. Caco-2 cell monolayer permeability among different groups was determined by measuring the concentrations of FITC-dextran in the lower compartments and transepithelial electrical resistance (TEER). Meanwhile, mRNA and protein expressions of tight junctions (TJs) were investigated. Generation of intracellular reactive oxygen species (ROS) and the ratio of cell apoptosis induced by BAs were assessed by fluorescence probe and flow cytometry. GXD was shown to keep the cell monolayer in low permeable status, increase TEER and mRNA and protein expressions of occludin (Ocln) and zonula occluden 2 (ZO2) remarkably in cells challenged with cholic acid (CA), deoxycholic acid (DCA) and glycocholic acid (GCA). However, no significant effects were uncovered against the pathological effects of taurocholic acid (TCA). Meanwhile, generation of ROS and increased levels of apoptotic cells caused by CA, DCA and GCA were dramatically decreased by GXD, which were not observed on TCA. GXD could significantly attenuate intestinal barrier dysfunction induced by BAs via TJs regulation, oxidative stress suppression and cell apoptosis decrease, but such effects and behind mechanisms differed among different kinds of BAs.

Abstract	People suffering from chronic respiratory diseases caused by air pollution need air filters simultaneously capable of high-efficiency filtration and respiration monitoring. However, constructing desirable filters to realize effective and durable capture of ultrafine particles as well as collection of real-time respiratory information is still particularly challenging. Herein, we report an ultralight, super-elastic hard carbon aerogel (s-HCA) as a piezoresistive sensor for a respiratory monitoring facial mask made of s-HCA/zein nanofibrils. The s-HCA displays super-elasticity and excellent compressive strength at a low density, as well as outstanding piezoresistive detective sensitivity and ranges. The resulting facial mask displays excellent filtration performance including high particulate efficiency and ultralow airflow resistance, as well as good moisture transferability. More significantly, ability of simultaneously monitoring the real-time respiratory process of filtration is incorporated into the facial mask. This study does not only lead to a novel carbon aerogel and broaden the application of carbon aerogels, but also provides a new strategy for the design of multifunctional facial masks. It is particularly significant for more patients under the situation of lack of costly respiratory equipment during the pandemic period.

Abstract	This study intends to obtain a kind of polymer-infiltrated ceramic-network (PICN) composite with improved performance for dental restoration. Porous ceramic network was prepared via compressing feldspar powders, followed by resin infiltration using Bis-GMA/TEGDMA or UDMA/TEGDMA mixtures to obtain PICN composites after thermocuring. The sintering parameters (temperature, duration) for the formation of feldspathic network with proper porosity were investigated. The ratios of resin mixtures were adjusted to optimize the infiltration. Comprehensive characterizations were conducted on the porosity and the shrinkage of preformed ceramic-networks, the viscosity of resin mixtures and their infiltration into the ceramic networks, as well as, flexural properties, Vickers hardness and wear resistance of the final PICN composites. It turned out that the PICN composite prepared from Bis-GMA/TEGDMA (6:4) achieved the best performance among all the samples, which is expected to be a suitable material for computer-aided design/computer-aided manufacturing (CAD/CAM) dental restorative applications.
