Improving the long-term cycling stability and energy density of all-solid-state lithium(Li)-metal batteries(ASSLMBs)at room temperature is a severe challenge because of the notorious solid–solid interfacial contact loss and sluggish ion transport.Solid electrolytes are generally studied as two-dimensional(2D)structures with planar interfaces,showing limited interfacial contact and further resulting in unstable Li/electrolyte and cathode/electrolyte interfaces.Herein,three-dimensional(3D)architecturally designed composite solid electrolytes are developed with independently controlled structural factors using 3D printing processing and post-curing treatment.Multiple-type electrolyte films with vertical-aligned micro-pillar(p-3DSE)and spiral(s-3DSE)structures are rationally designed and developed,which can be employed for both Li metal anode and cathode in terms of accelerating the Li+transport within electrodes and reinforcing the interfacial adhesion.The printed p-3DSE delivers robust long-term cycle life of up to 2600 cycles and a high critical current density of 1.92 mA cm^(−2).The optimized electrolyte structure could lead to ASSLMBs with a superior full-cell areal capacity of 2.75 mAh cm^(−2)(LFP)and 3.92 mAh cm^(−2)(NCM811).This unique design provides enhancements for both anode and cathode electrodes,thereby alleviating interfacial degradation induced by dendrite growth and contact loss.The approach in this study opens a new design strategy for advanced composite solid polymer electrolytes in ASSLMBs operating under high rates/capacities and room temperature.

Aqueous zinc ion batteries have been considered as the prominent candidate in the next-generation batteries for its low cost,safety and high theoretical capacity.Nonetheless,formation of zinc dendrites and side reactions at the electrode/electrolyte interface during the zinc plating/stripping process affect the cycling reversibility of the zinc anode.Regulation of the zinc plating/stripping process and realizing a highly reversible zinc anode is a great challenge.Herein,we applied a simple and effective approach of controlled-current zinc pre-deposition at copper mesh.At the current density of 40 mA cm^(-2),where the electron/ion transfers are both continuous and balanced,the Zn@CM-40 electrode with the(002)crystal plane orientation and the compactly aligned platelet morphology was successfully obtained.Compared with the zinc foil,the Zn@CM-40 exhibits greatly enhanced reversibility in the repeated plating/stripping(850 h at 1 mA cm^(-2))for the symmetric battery test.A series of characterization techniques including electrochemical analyses,XRD,SEM and optical microscopy observation,were used to demonstrate the correlation between the structure of pre-deposited zinc layer and the cycling stability.The COSMOL Multiphysics modeling demonstrates a more uniform electric field distribution in the Zn@CM than the zinc foil due to the aligned platelet morphology.Furthermore,the significant improvement is also achieved in a Zn||MnO_(2)full battery with a high capacity-retention(87%vs 47.8%).This study demonstrates that controlled-current electrodeposition represents an important strategy to regulate the crystal plane orientation and the morphology of the pre-deposited zinc layer,hence leading to the highly reversible and dendrite-free zinc anode for high-performance zinc ion batteries.

Three-dimensional(3D)printing,an additive manufacturing technique,is widely employed for the fabrication of various electrochemical energy storage devices(EESDs),such as batteries and supercapacitors,ranging from nanoscale to macroscale.This technique offers excellent manufacturing flexibility,geometric designability,cost-effectiveness,and eco-friendliness.Recent studies have focused on the utilization of 3D-printed critical materials for EESDs,which have demonstrated remarkable electrochemical performances,including high energy densities and rate capabilities,attributed to improved ion/electron transport abilities and fast kinetics.However,there is a lack of comprehensive reviews summarizing and discussing the recent advancements in the structural design and application of 3D-printed critical materials for EESDs,particularly rechargeable batteries.In this review,we primarily concentrate on the current progress in 3D printing(3DP)critical materials for emerging batteries.We commence by outlining the key characteristics of major 3DP methods employed for fabricating EESDs,encompassing design principles,materials selection,and optimization strategies.Subsequently,we summarize the recent advancements in 3D-printed critical materials(anode,cathode,electrolyte,separator,and current collector)for secondary batteries,including conventional Li-ion(LIBs),Na-ion(SIBs),K-ion(KIBs)batteries,as well as Li/Na/K/Zn metal batteries,Zn-air batteries,and Ni–Fe batteries.Within these sections,we discuss the 3DP precursor,design principles of 3D structures,and working mechanisms of the electrodes.Finally,we address the major challenges and potential applications in the development of 3D-printed critical materials for rechargeable batteries.

Aqueous rechargeable zinc ion batteries(ARZIBs)have received unprecedented attention owing to the low cost and high-safety merits.However,their further development and application are hindered by the issues of electrodes such as cathode dissolution,zinc anode dendrite,passivation,as well as sluggish reaction kinetics.Designing heterostructure electrodes is a powerful method to improve the electrochemical performance of electrodes by grafting the advantages of functional materials onto the active materials.In this review,various modified heterostructure electrodes with optimized electrochemical performance and wider applications are introduced.Moreover,the synergistic effect between active materials and functional materials are also in-depth analyzed.The specific modification methods are divided into interphase modification(electrode-electrolyte interphase and electrode-current collector interphase)and structure optimization.Finally,the conclusion and future perspective on the optimization mechanism of functional materials,and the cost issue of practical heterostructure electrodes in ARZIBs are also proposed.It is expected that this review can promote the further development of ARZIBs towards practical utility.

Switching the reaction routes in peroxymonosulfate(PMS)-based advanced oxidation processes have attracted much attention but remain challenging.Herein,a series of Co-N/C catalysts with different compositions and structures were prepared by using bimetallic zeolitic imidazolate frameworks based on ZIF-8 and ZIF-67(x Zn/Co-ZIFs).Results show that Co doping amount could mediate the transformation of the activation pathway of PMS over CoN/C.When Co doping amount was less than 10%,the constructed x Co-N/C/PMS system(x≤10%)was singlet oxygen-dominated reaction;however further increasing Co doping amount would lead to the generation and coexistence of sulfate radicals and high-valent cobalt,besides singlet oxygen.Furthermore,the nitrogen-coordinated Co(Co-NX)sites could serve as main catalytically active sites to generate singlet oxygen.While excess Co doping amount caused the formation of Co nanoparticles from which leached Co ions were responsible for the generation of sulfate radicals and high-valent cobalt.Compared to undoped N/C,Co doping could significantly enhance the catalytic performance.The 0.5%Co-N/C could achieve the optimum degradation(0.488 min^(-1))and mineralization abilities(78.4%)of sulfamethoxazole among the investigated Co-N/C catalysts,which was superior to most of previously reported catalysts.In addition,the application prospects of the two systems in different environmental scenarios(pH,inorganic anions and natural organic matter)were assessed and showed different degradation behaviors.This study provides a strategy to regulate the reactive species in PMS-based advanced oxidation process.

The unfolded protein response(UPR)is a cellular stress response pathway activated when the endoplasmic reticulum,a crucial organelle for protein folding and modification,encounters an accumulation of unfolded or misfolded proteins.The UPR aims to restore endoplasmic reticulum homeostasis by enhancing protein folding capacity,reducing protein biosynthesis,and promoting protein degradation.It also plays a pivotal role in coordinating signaling cascades to determine cell fate and function in response to endoplasmic reticulum stress.Recent research has highlighted the significance of the UPR not only in maintaining endoplasmic reticulum homeostasis but also in influencing various physiological processes in the nervous system.Here,we provide an overview of recent findings that underscore the UPR’s involvement in preserving the function and viability of neuronal and myelinating cells under physiological conditions,and highlight the critical role of the UPR in brain development,memory storage,retinal cone development,myelination,and maintenance of myelin thickness.

Background:Acute-on-chronic liver failure(ACLF)is a severe liver disease with complex pathogenesis.Clinical hypoglycemia is common in patients with ACLF and often predicts a worse prognosis.Accumulating evidence suggests that glucose metabolic disturbance,especially gluconeogenesis dysfunction,plays a critical role in the disease progression of ACLF.Lon protease-1(LONP1)is a novel mediator of energy and glucose metabolism.However,whether gluconeogenesis is a potential mechanism through which LONP1 modulates ACLF remains unknown.Methods:In this study,we collected liver tissues from ACLF patients,established an ACLF mouse model with carbon tetrachloride(CCl 4),lipopolysaccharide(LPS),and D-galactose(D-gal),and constructed an in vitro hypoxia and hyperammonemia-triggered hepatocyte injury model.LONP1 overexpression and knockdown adenovirus were used to assess the protective effect of LONP1 on liver injury and gluconeogenesis regulation.Liver histopathology,biochemical index,mitochondrial morphology,cell viability and apoptosis,and the expression and activity of key gluconeogenic enzymes were detected to explore the underlying protective mechanisms of LONP1 in ACLF.Results:We found that LONP1 and the expressions of gluconeogenic enzymes were downregulated in clinical ACLF liver tissues.Furthermore,LONP1 overexpression remarkably attenuated liver injury,which was characterized by improved liver histopathological lesions and decreased serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST)in ACLF mice.Moreover,mitochondrial morphology was improved upon overexpression of LONP1.Meanwhile,the expression and activity of the key gluconeogenic enzymes were restored by LONP1 overexpression.Similarly,the hepatoprotective effect was also observed in the hepatocyte injury model,as evidenced by improved cell viability,reduced cell apoptosis,and improved gluconeogenesis level and activity,while LONP1 knockdown worsened liver injury and gluconeogenesis disorders.Conclusion:We demonstrated that gluconeogenesis dysfunc

Resilience-incorporated seismic risk assessment of precast concrete frames with“dry”connections

引用

Earthquake Engineering and Engineering Vibration 2024年第2期23卷 403-425页

作者： wu Chenhao Tang Yuchuan Cao Xuyang wu Gang Key Laboratory of Concrete and Prestressed Concrete Structures of the Ministry of Education Nanjing 211102China Department of Civil and Environmental Engineering University of CaliforniaLos AngelesCA 90095USA School of Civil Engineering Southeast UniversityNanjing 211102China College of Civil and Transportation Engineering Hohai UniversityNanjing 210024China

A resilience-incorporated risk assessment framework is proposed and demonstrated in this study to manifest the advantageous seismic resilience of precast concrete frame(PCF)structures with“dry”connections in terms of their low damage and rapid recovery.The framework integrates various uncertainties in the seismic hazard,fragility,capacity,demand,loss functions,and post-earthquake recovery.In this study,the PCF structures are distinguished from ordinary reinforced concrete frame(RCF)structures by characterizing multiple limit states for the PCF based on its unique damage mechanisms.Accordingly,probabilistic story-wise pushover analyses are performed to yield story-wise capacities for the predefined limit states.In the seismic resilience analysis,a step-wise recovery model is proposed to idealize the functionality recovery process,with separate considerations of the repair and non-repair events.The recovery model leverages the economic loss and downtime to delineate the stochastic post-earthquake recovery curves for the resilience loss estimation.As such,contingencies in the probabilistic post-earthquake repairs are incorporated and the empirical judgments on the recovery parameters are largely circumvented.The proposed framework is demonstrated through a comparative study between two“dry”connected PCFs and one RCF designed as alternative structural systems for a prototype building.The results from the risk quantification indicate that the PCFs show reduced loss hazards and lower expected losses relative to the RCF.Particularly,the PCF equipped with energy dissipation devices at the“dry”connections largely reduces the expected economic loss,downtime,and resilience loss by 29%,56%,and 60%,respectively,compared to the RCF.

Aqueous zinc-ion batteries(AZIBs) have aroused significant research interest around the world in the past decade. The use of low-cost aqueous electrolytes and a metallic Zn anode with a suitable redox potential and high energy density make AZIBs a potential alternative to commercial Li-ion batteries in the development of next-generation batteries. However, owing to the narrow electrochemical stability window(ESW) of aqueous electrolytes, the choice of cathode materials is limited, because of which AZIBs exhibit a relatively low operating voltage and energy density. Hence, expanding the ESW of aqueous electrolytes is important for the development of practical AZIBs. This paper systematically reviews the electrolyte engineering strategies being explored to broaden the ESW of AZIBs. An in-depth analysis of high-voltage AZIBs is also presented. We suggest that the realization of high-voltage AZIBs depends on the synergistic development of suitable electrolytes and cathode materials. In addition, the cost associated with their fabrication as well as the use of standardized electrochemical tests should be considered during the design of high-voltage AZIBs.
