Environmental degradation has promoted the exploitation of novel energy-storage devices.Electrochemical en-ergy technologies,including supercapacitors and aqueous batteries,are highly desirable for energy storage appli-cations.Among them,aqueous zinc-based batteries(AZBs)are highly valued because of their inherent safety and low cost.One class of emerging materials favorably employed in these devices are organic cathodes,featuring resource renewability,cost-effectiveness,and adjustable electrochemical properties via facile structural modi-fication compared to the conventional inorganic cathodes.To date,various types of organic compounds have been developed and applied to AZBs.This paper comprehensively reviews the mechanisms involved in organic electrode material reactions,highlighting the structural modifications,including morphological,molecular,func-tional group,crystal,and electronic structures,affecting the final device performance.Conclusively,the prospects of practical applications of zinc/organic aqueous battery are delineated.

Two series of three dimensional(3D)lanthanide metal-organic frameworks(LnMOFs)of[Ln(tftpa)1.5(phen)(H_(2)O)]_(n)(Ln=Sm 1a,Eu 1b,Tb 1c,Dy 1d,H2tftpa=tetrafluoroterephthalic acid,phen=1,10-phenanthrolin)and[Ln(tftpa)1.5(bpy)(H_(2)O)]_(n)(Ln=Sm 2a,Eu 2b,Tb 2c,Dy 2d,bpy=2,2'-bipyridine)are obtained by structural regulation.Results reveal that the 3D LnMOFs show high water-and thermal-stability.Interestingly,through selecting the perfluorinated ligand,and using bpy as an auxiliary ligand to hold back the solvents near to the lanthanide ions,2b,and 2c show high luminescence quantum yield(QY)of 74.50%and 60.03%,respectively.In order to further improve the luminescence QY,the auxiliary ligand of phen with larger conjugation and more rigid structure is synthesized to replace bpy,and fortunately,higher luminescence QY of 80.73%(1b)and 75.17%(1c)are realized.

Poor conductivity and sluggish Na^(+) diffusion kinetic are two major drawbacks for practical application of sodium super-ionic conductor(NASICON) in sodium-ion batteries. In this work, we report a simple approach to synthesize quasi-inverse opal structural NASICON/N-doped carbon for the first time by a delicate one-pot solution-freeze drying-calcination process, aiming at fostering the overall electrochemical performance. Especially, the quasi-inverse opal structural Na_(3)V_(2)(PO_(4))_(3)/N-C(Q-NVP/N-C) displayed continuous pores, which provides interconnected channels for electrolyte permeation and abundant contacting interfaces between electrolyte and materials, resulting in faster kinetics of redox reaction and higher proportion of capacitive behavior.As a cathode material for sodium-ion batteries, the Q-NVP/N-C exhibits high specific capacity of 115 mAh·g^(-1) at 1C, still 61 mAh·g^(-1) at ultra-high current density of 100C,and a specific capacity of 89.7mAh·g^(-1) after 2000 cycles at 20C.This work displays the general validity of preparation method for not only Q-NVP/N-C,but also Na_(3)V_(2)(PO_(4))_(3),which provides a prospect for delicate synthesis of NASICON materials with excellent electrochemical performance.

Nowadays, the yearning for microwave absorption materials(MAMs) are more and more urgent for dealing with the increasingly serious electromagnetic pollution and the demand of modern military security.Among potential candidates, the graphene(GE) based magnetic hybrids have advantages in structural controllable and designing flexibility, providing opportunities for achieving highly efficiency of microwave absorption(MA). Thus, the structural regulation and MA performances of GE-based magnetic hybrids arouse great attention in related fields. In this review, we summarize the recently progress in MA performance of GE-based magnetic hybrids. Typical absorption process and corresponding mechanism are firstly introduced, for guiding the design of GE-based magnetic MAMs. Then, the magnetic components, synthesis methods, structural features and regulation strategies of these GE-related magnetic materials are reviewed, and their influences on MA performances have also been discussed. Challenges, and prospects of the GE-based magnetic MAMs are suggested. This review provides a brief but systematic introduction to GE-based magnetic MAMs, which may pave the way for the design of MAMs with highly efficient MA performances.

Nanoporous metals have received significant attention as a new class of structural and functional materials.However,the macroscopic brittle fracture under the tensile test is an impediment to their practical applications.Thus,it is of central importance to develop nanoporous materials with low cost and high tensile ductility.Herein,a nanoporous Cu film supported on a pure Cu substrate(NPC@Cu)was fabricated by utilizing a liquid Ga assisted alloying-dealloying strategy,and the thickness of NPC film can be precisely regulated by changing the mass loading of liquid Ga.In-situ X-ray diffraction was performed to further explore the alloying/dealloying mechanisms.The NPC@Cu films show good tensile mechanical properties with a minimum elongation of 13.5%,which can be attributed to the good interface bonding and certain modulus matching between the nanoporous Cu layer and the Cu substrate.Our findings demonstrate that the design of film-substrate structure provides a feasible strategy for enhancing the mechanical properties of nanoporous metals.

Layered materials with two-dimensional ion diffusion channels and fast kinetics are attractive as cathode materials for secondary batteries.However,one main challenge in potassium-ion batteries is the large ion size of K^(+),along with the strong K^(+)-K^(+)electrostatic repulsion.This strong interaction results in initial K deficiency,greater voltage slope,and lower specific capacity between set voltage ranges for layered transition metal oxides.In this review,a comprehensive review of the latest advancements in layered cathode materials for potassium-ion batteries is presented.Except for layered transition metal oxides,some polyanionic compounds,chalcogenides,and organic materials with the layered structure are introduced separately.Furthermore,summary and personal perspectives on future optimization and structural design of layered cathode materials are constructively discussed.We strongly appeal to the further exploration of layered polyanionic compounds and have demonstrated a series of novel layered structures including layered K_(3)V_(2)(PO_(4))_(3).

近十年来，从“双防”到“四万亿”强刺激，从强刺激到定向调控，从微刺激再到供给侧改革，从过度强调有效需求不足和危机管理转向强调潜在供给能力下降和结构性改革，一系列的宏观经济政策帮助我国积极应对全球金融危机，也越来越呈现出中国特色的宏观调控特点。表现在：配合总量政策，结构性调控力度不断加大；“三位一体”调控模式更加强化，短期调控与长期改革结合，政策连续性、协调性不断增强；宏观调控理念有所创新，提出宏观调控机制化，调控方式更加灵活。但调控目标的多元化决定了调控手段的泛化，目前我国的宏观经济政策在一定程度上存在过度干预微观经济的问题，这是导致宏观经济波动的原因之一。
