| 1 | Herbal decoctosome is a novel form of medicine显示文摘Traditionally, herbal medicine is consumed by drinking decoctions produced by boiling herbs with water. The functional components of the decoction are heat stable. Small RNAs(sRNAs) were reported as a new class of functional components in decoctions. However, the mechanisms by which sRNAs survive heat treatment of the decoction and enter cells are unclear.Previous studies showed that plant-derived exosome-like nanoparticles(ELNs), which we call botanosomes, could deliver therapeutic reagents in vivo. Here, we report that heat-stable decoctosomes(ELNs) from decoctions have more therapeutic effects than the decoctions in vitro and demonstrate therapeutic efficacy in vivo. Furthermore, sRNAs, such as HJT-sRNA-m7 and PGY-sRNA-6, in the decoctosome exhibit potent anti-fibrosis and anti-inflammatory effects, respectively. Decoctosome is comprised of lipids, chemical compounds, proteins, and s RNAs. A medical decoctosome mimic is called bencaosome. A single lipid sphinganine(d22:0) identified in the decoctosome was mixed and heated with the synthesized sRNAs to form the simplest bencaosome. This simple bencaosome structure was identified by critical micelle concentration(cmc) assay that sRNAs coassembled with sphinganine(d22:0) to form the lipid layers of vesicles. The heating process facilitates co-assembly of sRNAs and sphinganine(d22:0) until a steady state is reached. The artificially produced sphinganine-HJT-sRNA-m7 and sphinganinePGY-sRNA-6 bencaosomes could ameliorate bleomycin-induced lung fibrosis and poly(I:C)-induced lung inflammation, respectively, following oral administration in mice. Our study not only demonstrates that the herbal decoctosome may represent a combinatory remedy in precision medicine but also provides an effective oral delivery route for nucleic acid therapy. | Xiaoyun Li Zhu Liang Jianchao Du Zhiqing Wang Song Mei Zhiqing Li Yan Zhao DANDan Zhao Yiming Ma Jun Ye Jiantao Xu Yu Zhao Jiahui Chang Yuhao Qin Lanlan Yu Chenxuan Wang Chengyu Jiang | 2019 | Science China(Life Sciences)2019，62，3： | 26 |
| 2 | Sirt1-ROS-TRAF6 Signaling-Induced Pyroptosis Contributes to Early Injury in Ischemic Mice显示文摘Stroke is an acute cerebro-vascular disease with high incidence and poor prognosis,most commonly ischemic in nature.In recent years,increasing attention has been paid to inflammatory reactions as symptoms of a stroke.However,the role of inflammation in stroke and its underlying mechanisms require exploration.In this study,we evaluated the inflammatory reactions induced by acute ischemia and found that pyroptosis occurred after acute ischemia both in vivo and in vitro,as determined by interleukin-1β,apoptosis-associated speck-like protein,and caspase-1.The early inflammation resulted in irreversible ischemic injury,indicating that it deserves thorough investigation.Meanwhile,acute ischemia decreased the Sirtuin 1(Sirtl)protein levels,and increased the TRAF6(TNF receptor associated factor 6)protein and reactive oxygen species(ROS)levels.In further exploration,both Sirtl suppression and TRAF6 activation were found to contribute to this pyroptosis.Reduced Sirtl levels were responsible for the production of ROS and increased TRAF6 protein levels after ischemic exposure.Moreover,N-acetyl-L-cysteine,an ROS scavenger,suppressed the TRAF6 accumulation induced by oxygen-glucose deprivation via suppression of ROS bursts.These phenomena indicate that Sirtl is upstream of ROS,and ROS bursts result in increased TRAF6 levels.Further,the activation of Sirtl during the period of ischemia reduced ischemiainduced injury after 72 h of reperfusion in mice with middle cerebral artery occlusion.In sum,these results indicate that pyroptosis-dependent machinery contributes to the neural injury during acute ischemia via the Sirt1-ROS-TRAF6 signaling pathway.We propose that inflammatory reactions occur soon after oxidative stress and are detrimental to neuronal survival;this provides a promising therapeutic target against ischemic injuries such as a stroke. | Weijie Yan Wei Sun Jiahui Fan Haiqing Wang Song Han Junfa Li Yanling Yin | 2020 | Neuroscience Bulletin2020，36，8： | 9 |
| 3 | Aeroacoustic and aerodynamic optimization of propeller blades显示文摘It is of great significance to develop a high-efficiency and low-noise propeller optimization method for new-generation propeller aircraft design.Coupled with free form deformation method,dynamic mesh interpolation technology,optimization algorithm,surrogate model,aerodynamic calculation and aeroacoustic prediction model module,the integrated aerodynamic and aeroacoustic design method of propeller is built.The optimization design for the six-blade propeller is carried out.The non-reduction in efficiency,thrust coefficient and the minimum of aerodynamic noise is treated as the optimization design objective.The spatial vorticity distribution of the propeller before and after the design is also analyzed by using unsteady computational fluid dynamics method.The results show that the optimized propeller can effectively reduce the aerodynamic noise level.The maximum total sound pressure level can be reduced by 5 dB without reducing its aerodynamic performance.The developed method has good application potential in low-noise optimization design of propeller and other rotating machinery. | Peixun YU Jiahui PENG Junqiang BAI Xiao HAN Xiang SONG | 2020 | Chinese Journal of Aeronautics2020，33，3： | 4 |
| 4 | A data-driven framework to predict the morphology of interfacial Cu6Sn5 IMC in SAC/Cu system during laser soldering显示文摘A data-driven approach combining together the experimental laser soldering,finite element analysis and machine learning,has been utilized to predict the morphology of interracial intermetallic compound(IMC) in Sn-xAg-yCu/Cu(SAC/Cu) system.Six types of SAC solders with varying weight proportion of Ag and Cu,have been processed with fiber laser at different magnitudes of power(30-50 W) and scan speed(10-240 mm/min),and the resultant IMC morphologies characterized through scanning electron microscope are categorized as prismatic and scalloped ones.For the different alloy composition and laser parameters,finite element method(FEM) is employed to compute the transient distribution of temperature at the interface of solder and substrates.The FEM-generated datasets are supplied to a neural network that predicts the IMC morphology through the quantified values of temperature dependent Jackson parameter(αJ).The numerical value of αJ predicted from neural network is validated with experimental IMC morphologies.The critical scan speed for the morphology transition between prismatic and scalloped IMC is estimated for each solder composition at a given power.Sn-0.7 Cu having the largest critical scan speed at 30 W and Sn-3.5 Ag alloy having the largest critical scan speed at input power values of 40 W and 50 W,thus possessing the greatest likelihood of forming prismatic interfacial IMC during laser soldering,can be inferred as most suitable SAC solders in applications exposed to shear loads. | Anil Kunwar Lili An Jiahui Liu Shengyan Shang Peter Raback Haitao Ma Xueguan Song | 2020 | Journal of Materials Science & Technology2020，47，15： | 3 |

| 6 | Construction of Cu-Ce interface for boosting toluene oxidation:Study of Cu-Ce interaction and intermediates identified by in situ DRIFTS显示文摘A facile hydrothermal method was applied to gain stably and highly efficient CuO-CeO_(2)(denoted as Cu1Ce2)catalyst for toluene oxidation.The changes of surface and inter properties on Cu1Ce2 were investigated comparing with pure CeO_(2)and pure CuO.The formation of Cu-Ce interface promotes the electron transfer between Cu and Ce through Cu^(2+)+Ce^(3+)↔Cu^(+)+Ce^(4+)and leads to high redox properties and mobility of oxygen species.Thus,the Cu1Ce2 catalyst makes up the shortcoming of CeO_(2)and CuO and achieved high catalytic performance with T_(50)=234°C and T_(99)=250°C(the temperature at which 50%and 90%C_(7)H_(8)conversion is obtained,respectively)for toluene oxidation.Different reaction steps and intermediates for toluene oxidation over Cu1Ce2,CeO_(2)and CuO were detected by in situ DRIFTS,the fast benzyl species conversion and preferential transformation of benzoates into carbonates through C=C breaking over Cu1Ce2 should accelerate the reaction. | Jiahui Lu Jinping Zhong Quanming Ren Jiaqi Li Linghe Song Shengpeng Mo Mingyuan Zhang Peirong Chen Mingli Fu Daiqi Ye | 2021 | Chinese Chemical Letters2021，32，11： | 2 |
| 7 | Thermal insulation design for efficient and scalable solar water interfacial evaporation and purification显示文摘In recent years, solar desalination and water evaporation/purification with various artificial architectures have drawn significant attention. Herein, we introduce a rational design structure for efficient solar water evaporation and purification, focusing on the balance between water transportation and thermal insulation.Natural wood after a simple flame treatment on the surface was utilized as the solar absorber, with a high solar absorbance(~90 %), good hydrophilicity, and excellent heat localization abilities. Besides,a thermal insulator(polystyrene foam) was used to further reduce the thermal loss, and the optimized ratio between the water path and thermal insulator was obtained. A set of floating foam-flamed-wood(F-F-wood) devices were fabricated with a high evaporation rate of 3.92 kgm-2 h-1, exhibiting photothermal purification abilities from seawater and wastewater containing organic dyes and heavy metals. This study sheds light on the rational design of scalable and low-cost devices for solar water evaporation and purification. | Jiahui Chen Dainan Zhang Song He Gengpei Xia Xiaoyi Wang Quanjun Xiang Tianlong Wen Zhiyong Zhong Yulong Liao | 2021 | Journal of Materials Science & Technology2021，，7： | 1 |
| 8 | Atomic-level insights into surface engineering of semiconductors for photocatalytic CO_(2) reduction显示文摘Photocatalytic conversion of CO_(2)into solar fuels provides a bright route for the green and sustainable development of human society.However,the realization of efficient photocatalytic CO_(2)reduction reaction(CO_(2)RR)is still challenging owing to the sluggish kinetics or unfavorable thermodynamics for basic chemical processes of CO_(2)RR,such as adsorption,activation,conversion and product desorption.To overcome these shortcomings,recent works have demonstrated that surface engineering of semiconductors,such as introducing surface vacancy,surface doping,and cocatalyst loading,serves as effective or promising strategies for improved photocatalytic CO_(2)RR with high activity and selectivity.The essential reason lies in the activation and reaction pathways can be optimized and regulated through the reconstruction of surface atomic and electronic structures.Herein,in this review,we focus on recent research advances about rational design of semiconductor surface for photocatalytic CO_(2)RR.The surface engineering strategies for improved CO_(2)adsorption,activation,and product selectivity will be reviewed.In addition,theoretical calculations along with in situ characterization techniques will be in the spotlight to clarify the kinetics and thermodynamics of the reaction process.The aim of this review is to provide deep understanding and rational guidance on the design of semiconductors for photocatalytic CO_(2)RR. | Hengming Huang Hui Song Jiahui Kou Chunhua Lu Jinhua Ye | 2022 | Journal of Energy Chemistry2022，31，4： | 1 |
| 9 | Waste to wealth: Oxygen-nitrogen-sulfur codoped lignin-derived carbon microspheres from hazardous black liquors for high-performance DSSCs显示文摘Carbon materials are effective substitutes for Pt counter electrodes(CEs) in dye-sensitized solar cells(DSSCs). However, many of these materials, such as carbon nanotubes and graphene, are expensive and require complex preparation process. Herein, waste lignin, recycled from hazardous black liquors,is used to create oxygen-nitrogen-sulfur codoped carbon microspheres for use in DSSC CEs through the facile process of low-temperature preoxidation and high-temperature self-activation. The large number of ester bonds formed by preoxidation increase the degree of cross-linking of the lignin chains, leading to the formation of highly disordered carbon with ample defect sites during pyrolysis. The presence of organic O/N/S components in the waste lignin results in high O/N/S doping of the pyrolysed carbon,which increases the electrolyte ion adsorption and accelerates the electron transfer at the CE/electrolyte interface, as confirmed by density functional theory(DFT) calculations. The presence of inorganic impurities enables the construction of a hierarchical micropore-rich carbon structure through the etching effect during self-activation, which can provide abundant catalytically active sites for the reversible adsorption/desorption of electrolyte ions. Under these synergistic effects, the DSSCs that use this novel carbon CE achieve a quite high power-conversion efficiency of 9.22%. To the best of our knowledge, the value is a new record reported so far for biomass-carbon-based DSSCs. | Wenjie Cheng Caichao Wan Xingong Li Huayun Chai Zhenxu Yang Song Wei Jiahui Su Xueer Tang Yiqiang Wu | 2023 | Journal of Energy Chemistry2023，，8： | 1 |
| 10 | Miniaturization of mechanical actuators in skin-integrated electronics for haptic interfaces显示文摘Skin-integrated electronics,also known as electronic skin(e-skin);are rapidly developing and are gradually being adopted in biomedical fields as well as in our daily lives.E-skin capable of providing sensitive and high-resolution tactile sensations and haptic feedback to the human body would open a new e-skin paradigm for closed-loop human-machine interfaces.Here,we report a class of materials and mechanical designs for the miniaturization of mechanical actuators and strategies for their integration into thin,soft e-skin for haptic interfaces.The mechanical actuators exhibit small dimensions of 5 mm diameter and 1.45 mm thickness and work in an electromagnetically driven vibrotactile mode with resonance frequency overlapping the most sensitive frequency of human skin.Nine mini actuators can be integrated simultaneously in a small area of 2 cm×2 cm to form a 3×3 haptic feedback array,which is small and compact enough to mount on a thumb tip.Furthermore,the thin,soft haptic interface exhibits good mechanical properties that work properly during stretching,bending,and twisting and therefore can conformally fit onto various parts of the human body to afford programmable tactile enhancement and Braille recognition with an accuracy rate over 85%. | Dengfeng Li Jiahui He Zhen Song Kuanming Yao Mengge Wu Haoran Fu Yiming Liu Zhan Gao Jingkun Zhou Lei Wei Zhengyou Zhang Yuan Dai Zhaoqian Xie Xinge Yu | 2021 | Microsystems & Nanoengineering2021，7，5： | 1 |

| 12 | Research on security situation awareness algorithm of Markov differential game block-chain model显示文摘To analyze the impact of solar eclipse attacks on the block-chain network and comprehensively and accurately evaluate the security of the current system,a method based on the Markov differential is proposed to solve the problem that it is difficult to meet the multi-stage continuous real-time randomness in the current block-chain network attack and defense process.Block-chain network security situation awareness method based on game model.This method analyzes the security data generated by the solar eclipse attack,establishes the corresponding attack graph,and classifies the offensive and defensive strengths of the offensive and defensive parties.Through a multi-stage offensive and defensive game,the security level of each node of the blockchain system is combined with the final objective function value comprehensively evaluates the real-time security status of the system.The results of simulation experiments show that the proposed model and algorithm can not only effectively evaluate the overall security of the blockchain network,but also have feasibility in predicting the future security status. | Luo Zhiyong Wang Shuyi Song Weiwei Liu Jiahui Wang Jianming | 2023 | The Journal of China Universities of Posts and Telecommunications2023，30，4： | 0 |
| 13 | SERS monitoring of photoinduced-enhanced oxidative stress amplifier on Au@carbon dots for tumor catalytic therapy显示文摘Currently,artificial enzymes-based photodynamic therapy(PDT)is attractive due to its efficient capacity to change the immunosuppressive tumor microenvironment(TME).It is of great significance to study the therapeutic mechanism of novel artificial enzymes in TME through a monitoring strategy and improve the therapeutic effect.In this study,Au@carbon dots(Au@CDs)nanohybrids with a core-shell structure are synthesized,which not only exhibit tunable enzyme-mimicking activity under near-infrared(NIR)light,but also excellent surface-enhanced Raman scattering(SERS)properties.Therefore,Au@CDs show a good capability for monitoring NIR-photoinduced peroxidase-like catalytic processes via a SERS strategy in tumor.Moreover,the Au@CDs deplete glutathione with the cascade catalyzed reactions,thus elevating intratumor oxidative stress amplifying the reactive oxygen species damage based on the NIR-photoinduced enhanced peroxidase and glutathione oxidase-like activities,showing excellent and fast PDT therapeutic effect promoted by photothermal property in 3 min,finally leading to apoptosis in cancer cells.Through SERS monitoring,it is further found that after removing the NIR light source for 33 min,the reactive oxygen species(ROS)activity of the TME is counteracted and eliminated due to the presence of glutathione.This work presents a guidance to rationally design of artificial enzyme for ROS-involved therapeutic strategies and a new spectroscopic tool to evaluate the tumor catalytic therapy. | Linjia Li Jin Yang Jiahui Wei Chunhuan Jiang Zhuo Liu Bai Yang Bing Zhao Wei Song | 2022 | Light(Science & Applications)2022，11，10： | 0 |
| 14 | Influence of extracellular polymeric substances from activated sludge on the aggregation kinetics of silver and silver sulfide nanoparticles显示文摘Extracellular polymeric substances(EPS)in activated sludge from wastewater treatment plants(WWTPs)could affect interactions between nanoparticles and alter their migration behavior.The influence mechanisms of silver nanoparticles(Ag NPs)and silver sulfide nanoparticles(Ag_(2)S NPs)aggregated by active EPS sludge were studied in monovalent or divalent cation solutions.The aggregation behaviors of the NPs without EPS followed the Derjaguin-Landau-Verwey-Overbeek(DLVO)theory.The counterions aggravated the aggregation of both NPs,and the divalent cation had a strong neutralizing effect due to the decrease in electrostatic repulsive force.Through extended DLVO(EDLVO)model analysis,in NaNO3 and low-concentration Ca(NO_(3))_(2)(<10 mmol/L)solutions,EPS could alleviate the aggregation behaviors of Cit-Ag NPs and Ag_(2)S NPs due to the enhancement of steric repulsive forces.At high concentrations of Ca(NO_(3))_(2)(10‒100 mmol/L),exopolysaccharide macromolecules could promote the aggregation of Cit-Ag NPs and Ag_(2)S NPs by interparticle bridging.As the final transformation form of Ag NPs in water environments,Ag_(2)S NPs had better stability,possibly due to their small van der Waals forces and their strong steric repulsive forces.It is essential to elucidate the surface mechanisms between EPS and NPs to understand the different fates of metal-based and metal-sulfide NPs in WWTP systems. | Wanpeng Chen Jiahui Song Shaojie Jiang Qiang He Jun Ma Xiaoliu Huangfu | 2022 | Frontiers of Environmental Science & Engineering2022，16，2： | 0 |
| 15 | Avian influenza viruses suppress innate immunity by inducingtrans-transcriptional readthrough via SSU72显示文摘Innate immunity plays critical antiviral roles. The highly virulent avian influenza viruses (AIVs) H5N1, H7N9, and H5N6 can betterescape host innate immune responses than the less virulent seasonal H1N1 virus. Here, we report a mechanism by whichtranscriptional readthrough (TRT)-mediated suppression of innate immunity occurs post AIV infection. By using cell lines, mouselungs, and patient PBMCs, we showed that genes on the complementary strand (“trans” genes) influenced by TRT were involved inthe disruption of host antiviral responses during AIV infection. The trans-TRT enhanced viral lethality, and TRT abolishmentincreased cell viability and STAT1/2 expression. The viral NS1 protein directly bound to SSU72, and degradation of SSU72 inducedTRT. SSU72 overexpression reduced TRT and alleviated mouse lung injury. Our results suggest that AIVs infection induce TRT byreducing SSU72 expression, thereby impairing host immune responses, a molecular mechanism acting through the NS1-SSU72-trans-TRT-STAT1/2 axis. Thus, restoration of SSU72 expression might be a potential strategy for preventing AIV pandemics. | Yan Zhao Fengming Huang Zhen Zou Yuhai Bi Yang Yang Cong Zhang Qiang Liu Daozhen Shang Yiwu Yan Xiangwu Ju Song Mei Peng Xie Xiao Li Mingyao Tian Shuguang Tan Huijun Lu Zongsheng Han Kangtai Liu Yuqing Zhang Junbo Liang Zhu Liang Qingchao Zhang Jiahui Chang William JLiu Cong Feng Tanshi Li Michael Q.Zhang Xiaoyue Wang George FGao Yingxia Liu Ningyi Jin Chengyu Jiang | 2022 | Cellular & Molecular Immunology2022，19，6： | 0 |
| 16 | The selective regulation of immune responses by matrix metalloproteinase MMP14 in Ostrinia furnacalis显示文摘Matrix metalloproteinases (MMPs) are crucial for tissue remodeling and immune responses in insects, yet it remains unclear how MMPs affect the various immune processes against pathogenic infections and whether the responses vary among insects. In this study, we used the lepidopteran pest Ostrinia furnacalis larvae to address these questions by examining the changes of immune-related gene expression and antimicrobial activity after the knockdown of MMP14 and bacterial infections. We identified MMP14 in O. furnacalis using the rapid amplification of complementary DNA ends (RACE), and found that it was conserved and belonged to the MMP1 subfamily. Our functional investigations revealed that MMP14 is an infection-responsive gene, and its knockdown reduces phenoloxidase (PO) activity and Cecropin expression, while the expressions of Lysozyme, Attacin, Gloverin, and Moricin are enhanced after MMP14 knockdown. Further PO and lysozyme activity determinations showed consistent results with gene expression of these immune-related genes. Finally, the knockdown of MMP14 decreased larvae survival to bacterial infections. Taken together, our data indicate that MMP14 selectively regulates the immune responses, and is required to defend against bacterial infections in O. furnacalis larvae. Conserved MMPs may serve as a potential target for pest control using a combination of double-stranded RNA and bacterial infection. | Kangkang Chen Shiqi Lu Jiahui Song Xiaoyi Dou Xiangyi Wei Xinyan Wang Xu Liu Congjing Feng | 2023 | Insect Science2023，30，6： | 0 |
| 17 | Resource allocation optimization for SWIPT full-duplex relaying networks with practical energy harvester显示文摘In this paper,the resource allocation optimization for the simultaneous wireless information and power transfer(SWIPT)full-duplex(FD)relaying networks is investigated,in which the power-constrained relay scavenges energy from the source signal and assists information transmission by FD operation.Taking into account non-linear energy harvesting(EH)hardware circuit characteristics of the relay,the information rate maximization problem is developed by jointly optimizing the time-switching(TS)factor and transmission powers of the source in two different phases.However,the formulated optimization is highly non-convex and difficult to solve.To cope with this problem,the primary problem is decomposed into two sub-problems with respect to the TS factor and transmission powers.After solving these two sub-problems,the final sub-optimal solutions can be obtained by alternating search.Simulation results prove that the optimization of both TS factor and transmission powers can effectively enhance the information rate for the considered networks. | Xu Siyang Song Xin Zhu Jiahui | 2023 | The Journal of China Universities of Posts and Telecommunications2023，30，1： | 0 |

| 19 | Metal-organic framework-based single-atom electro-/ photocatalysts: Synthesis, energy applications, and opportunities显示文摘Single-atom catalysts(SACs)have gained substantial attention because of their exceptional catalytic properties.However,the high surface energy limits their synthesis,thus creating significant challenges for further development.In the last few years,metal–organic frameworks(MOFs)have received significant consideration as ideal candidates for synthesizing SACs due to their tailorable chemistry,tunable morphologies,high porosity,and chemical/thermal stability.From this perspective,this review thoroughly summarizes the previously reported methods and possible future approaches for constructing MOF-based(MOF-derived-supported and MOF-supported)SACs.Then,MOF-based SAC's identification techniques are briefly assessed to understand their coordination environments,local electronic structures,spatial distributions,and catalytic/electrochemical reaction mechanisms.This review systematically highlights several photocatalytic and electrocatalytic applications of MOF-based SACs for energy conversion and storage,including hydrogen evolution reactions,oxygen evolution reactions,O_(2)/CO_(2)/N_(2) reduction reactions,fuel cells,and rechargeable batteries.Some light is also shed on the future development of this highly exciting field by highlighting the advantages and limitations of MOF-based SACs. | Munir Ahmad Jiahui Chen Jianwen Liu Yan Zhang Zhongxin Song Shahzad Afzal Waseem Raza Liaqat Zeb Andleeb Mehmood Arshad Hussain Jiujun Zhang Xian-Zhu Fu Jing-Li Luo | 2024 | Carbon Energy2024，6，1： | 0 |
| 20 | Efficient conversion of lignin waste and self-assembly synthesis of C@MnCo_(2)O_(4)for asymmetric supercapacitors with high energy density显示文摘Lignin waste from the papermaking and biorefineries industry is a significantly promising renewable resource to prepare advanced carbon materials for diverse applications,such as the electrodes of supercapacitors;however,the improvement of their energy density remains a challenge.Here,we design a green and universal approach to prepare the composite electrode material,which is composed of lignin-phenolformaldehyde resins derived hierarchical porous carbon(LR-HPC)as conductive skeletons and the self-assembly manganese cobaltite(MnCo_(2)O_(4))nanocrystals as active sites.The synthesized C@MnCo_(2)O_(4)composite has an abundant porous structure and superior electronic conductivity,allowing for more charge/electron mass transfer channels and active sites for the redox reactions.The composite shows excellent electrochemical performance,such as the maximum specific capacitance of~726 mF cm^(-2)at 0.5 mV s^(-1),due to the significantly enhanced interactive interface between LR-HPC and MnCo_(2)O_(4)crystals.The assembled all-solid-state asymmetric supercapacitor,with the LR-HPC and C@MnCo_(2)O_(4)as cathode and anode,respectively,exhibits the highest volumetric energy density of 0.68 mWh cm^(-3)at a power density of 8.2 mW cm^(-3).Moreover,this device shows a high capacity retention ratio of~87.6%at 5 mA cm^(-2)after 5000 cycles. | Jiahui Mu Cuihuan Li Jiankang Zhang Xianliang Song Sheng Chen Feng Xu | 2023 | Green Energy & Environment2023，8，5： | 0 |
