| 1 | Interfacial Microstructure and Properties of a Vacuum Hot Roll-bonded Titanium-Stainless Steel Clad Plate with a Niobium Interlayer显示文摘Vacuum hot roll bonding(VHRB)was used to bond pure titanium(Ti)plate to a 304 stainless steel(SS)plate with a niobium(Nb)interlayer,with the aim of producing a high-quality Ti-SS clad plate.The roll-bonding process was performed at diferent temperatures in the range of 850–1000 C,followed by characterization of microstructure and mechanical properties.The study demonstrates that the interfaces are free from cracks and discontinuities,and interdifusion between the stainless steel and the titanium is efectively prevented by inserting a layer of pure Nb foil.No intermetallic reaction layer occurred at the Nb-Ti interface at any of the investigated temperatures.An intermetallic FeNb phase was formed at the Nb-SS interface when bonding was performed at 950 C and above.The presence of the FeNb layer was confirmed by x-ray difraction.The maximum shear strength of^396 MPa was obtained when bonding is carried out at 900 C.However,the formation of the FeNb layer at roll bonding temperature greater than 900 C led to decrease in shear strength.Ductile fracture occurred through the Ti-Nb interface for roll-bonded temperatures of up to 900 C.On the other hand,at temperature of 950 C and above,failure occurred through the Nb-SS interface,with brittle fracture characteristics. | Zongan LUO Guanglei WANG Guangming XIE Lipeng WANG Kun ZHAO | 2013 | Acta Metallurgica Sinica(English Letters)2013,26,6: | 18 |
| 2 | Controlling effects of differential swelling index on evolution of coal permeability显示文摘Coal permeability measurements are normally conducted under the assumption that gas pressure in the matrix is equalized with that in fracture and that gas sorption-induced swelling/shrinking strain is uniformly distributed within the coal.However,the validity of this assumption has long been questioned and differential strain between the fracture strain and the bulk strain has long been considered as the primary reason for the inconsistency between experimental data and poroelasticity solutions.Although efforts have been made to incorporate the impact into coal permeability models,the fundamental nature of those efforts to split the matrix strain between fracture and coal bulk remains questionable.In this study,a new concept of differential swelling index(DSI)was derived to theoretically define the relation among sorption-induced strains of the coal bulk,fracture,and coal matrix at the equilibrium state.DSI was a function of the equilibrium pressure and its magnitudes were regulated by the Langmuir constants of both the matrix and the coal bulk.Furthermore,a spectrum of DSI-based coal permeability models was developed to explicitly consider the effect of differential strains.These models were verified with the experimental data under the conditions of uniaxial strain,constant confining pressure,and constant effective stress. | Chuanzhong Jiang Zhenfeng Zhao Xiwei Zhang Jishan Liu Derek Elsworth Guanglei Cui | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020,12,3: | 5 |
| 3 | Multicomponent Nanoparticles Synergistic One-Dimensional Nanofibers as Heterostructure Absorbers for Tunable and Efficient Microwave Absorption显示文摘Application of novel radio technologies and equip-ment inevitably leads to electromagnetic pollution.One-dimensional polymer-based composite membrane structures have been shown to be an effective strategy to obtain high-performance microwave absorbers.Herein,we reported a one-dimensional N-doped carbon nanofibers material which encapsulated the hollow Co_(3)SnC_(0.7) nano-cubes in the fiber lumen by electrospinning.Space charge stacking formed between nanoparticles can be channeled by longitudinal fibrous structures.The dielectric constant of the fibers is highly related to the carbonization temperature,and the great impedance matching can be achieved by synergetic effect between Co_(3)SnC_(0.7) and carbon network.At 800℃,the necklace-like Co_(3)SnC_(0.7)/CNF with 5%low load achieves an excellent RL value of−51.2 dB at 2.3 mm and the effective absorption bandwidth of 7.44 GHz with matching thickness of 2.5 mm.The multiple electromagnetic wave(EMW)reflections and interfacial polarization between the fibers and the fibers internal contribute a major effect to attenuating the EMW.These strategies for regulating electromagnetic performance can be expanded to other electromagnetic functional materials which facilitate the development of emerging absorbers. | Chenxi Wang Yue Liu Zirui Jia Wanru Zhao Guanglei Wu | 2023 | Nano-Micro Letters2023,15,1: | 3 |
| 4 | Generation and characterization of stable pig pregastrulation epiblast stem cell lines显示文摘Pig epiblast-derived pluripotent stem cells are considered to have great potential and broad prospects for human therapeutic model developme nt and livestock breeding.Despite on going attempts since the 1990s,no stably defined pig epiblast-derived stem cell line has bee n established.Here,guided by in sights from a large-scale sin gle-cell tran scriptome an alysis of pig embryos from embryonic day(E)0 to E14,specifically,the tracing of pluripotency changes during epiblast development,we developed an in vitro culture medium for establishing and maintaining stable pluripotent stem cell lines from pig E10 pregastrulation epiblasts(pgEpiSCs).Enabled by chemical inhibition of WNT-related signaling in combination with growth factors in the FGF/ERK,JAK/STAT3,and Activin/Nodal pathways,pgEpiSCs maintain their pluripotency transcriptome features,similar to those of E10 epiblast cells,and normal karyotypes after more than 240 passages and have the potential to differentiate into three germ layers.Strikingly,ultradeep in situ Hi-C analysis revealed functional impacts of chromatin 3D-spatial associations on the transcriptional regulation of pluripote ncy marker genes in pgEpiSCs.I n practice,we con firmed that pgEpiSCs readily tolerate at least three rounds of successive gene editi ng and gene rated cloned gen e-edited live piglets.Our findings deliver on the long-a nticipated promise of pig pluripote nt stem cells and open new avenues for biological research,animal husbandry,and regenerative biomedicine. | Minglei Zhi Jinying Zhang Qianzi Tang Dawei Yu Shuai Gao Dengfeng Gao Pengliang Liu Jianxiong Guo Tang Hai Jie Gao Suying Cao Zimo Zhao Chongyang Li Xiaogang Weng Mengnan He Tianzhi Chen Yingjie Wang Keren Long Deling Jiao Guanglei Li Jiaman Zhang Yan Liu Yu Lin Daxin Pang Qianqian Zhu Naixin Chen Jingjing Huang Xinze Chen Yixuan Yao Jingcang Yang Zicong Xie Xianya Huang Mengxin Liu Ran Zhang Qiuyan Li Yiliang Miao Jianhui Tian Xingxu Huang Hongsheng Ouyang Bofeng Liu Wei Xie Qi Zhou Zhonghua Liu Caihong Zheng Mingzhou Li Jianyong Han | 2022 | Cell Research2022,32,4: | 3 |
| 5 | Tuning microwave absorption properties of Ti_(3)C_(2)T_(x) MXene-based materials:Component optimization and structure modulation显示文摘The current electromagnetic environment brings a growing demand for efficient microwave absorption(MA)materials.Ti_(3)C_(2)T_(x) MXene,one of the 2D transition-metal carbides,is considered to be a promising MA material owing to its superior dielectric properties and structural processability.In order to further improve the MA performance and environmental adaptability of Ti_(3)C_(2)T_(x) MXene,Ti_(3)C_(2)T_(x) MXene-based MA materials enhanced by composition and structure design have been extensively studied and the regu-lation ideas for its MA properties can be outlined as component optimization and structure manipulation strategies based on the microwave absorption mechanism.Herein,we briefly introduced the microwave absorption mechanism and focused on the design strategies of Ti_(3)C_(2)T_(x) MXene-based MA materials based on recent advances.In addition,the prospects of Ti_(3)C_(2)T_(x) MXene-based MA materials were also discussed. | Ming Chang Qingyu Li Zirui Jia Wanru Zhao Guanglei Wu | 2023 | Journal of Materials Science & Technology2023,,17: | 3 |
| 6 | Assessment of ecosystem services value in response to prevailing and future land use/cover changes in Lahore,Pakistan显示文摘Land use/cover changes(LUCCs)significantly affect ecosystem services(ESs)and their corresponding monetary value.ESs can be evaluated to analyze the ecological and environmental changes caused by LUCCs.This research aims to estimate variations in the ecosystem services value(ESV)due to LUCCs in Lahore of Pakistan,and to offer information and recommendations to policy-makers concerned with the economic improvement of metropolis areas.We first investigated the historical LUCCs from 1990 to 2019,and then simulated the future land use/cover in 2030 and 2050 based on the CA-Markov model under three scenarios,including business-as-usual(BAU),rapid economic growth(REG),and coordinated environmental sustainability(CES).Subsequently,we evaluated the ESV from 1990 to 2050 and evaluated the historical and potential future ESV changes induced by LUCCs during 1990–2019 and 2019–2050,respectively.The results showed that,land use/cover exhibited an increase in built-up land and decreases in vegetation,water body,and unused land both in the past and future.The net ESV decreased from 58.26 million USD in 1990 to 50.31 million USD in 2019.In 2050,the decrease in ESV is most rapid under the REG scenario(decrease ESV of 7.13 million USD and decrease percentage of 14.18%),followed by the BAU(decrease ESV of 5.61 million USD and decrease percentage of 11.15%)and CES(decrease ESV of 5.18 million USD and decrease percentage of 10.30%)scenarios.For each ecosystem service type,the ESV of waste treatment decreased by 18.37%from 1990 to 2019,followed by soil formation and conservation(17.52%),biodiversity and maintenance(13.23%),climate regulation(11.80%),food production(11.69%),hydrological regulation(11.11%),and aesthetic value(3.07%).These outcomes indicate that continuous land use/cover planning should focus on regenerating aquatic areas and vegetation restoration. | Mobeen Akhtar Yuanyuan Zhao Guanglei Gao Qudsia Gulzar Azfar Hussain Abdus Samie | 2020 | Regional Sustainability2020,1,1: | 2 |
| 7 | Spatiotemporal patterns of the forage-livestock balance in the Xilin Gol steppe,China:implications for sustainably utilizing grassland-ecosystem services显示文摘Understanding the spatiotemporal patterns of the forage-livestock balance is imperative for regionally arranging animal husbandry production while ensuring sustainable grassland-ecosystem service use.The Xilin Gol steppe is an important native grassland resource in Inner Mongolia Autonomous Region,China.This study aimed to elucidate the dynamics of the forage-livestock balance in the Xilin Gol steppe during the period 2000–2015.We evaluated the forage production and corresponding livestock carrying capacity(LCC)in the growing seasons of 2000–2015 using remote sensing data and field surveys.The spatiotemporal patterns of the forage-livestock balance were then assessed at regional,city(including city,county and banner),and village scales using statistical and household survey data.The results showed that both forage production and LCC decreased in the Xilin Gol steppe from east to west.During the period 2000–2015,the regional average forage production and corresponding LCC fluctuated without following a distinct trend,but were consistent with the variations in precipitation.The forage-livestock balance varied with time,space,and scale.At the regional scale,steppes were overgrazed in the early 2000s,but a forage-livestock balance or even grazing potential was achieved in other years.At the city scale,approximately half of the region exhibited a'forage-livestock balance'since 2000.However,about half of the region still experienced overgrazing,which mainly located in the southwest sandy zones.Such changes may have been affected by the variations in grassland quality,forage production,compensation payment,and so on.We suggest a location-specific management scheme for grazing constraints,ecological compensation payment,and industry development to aid in harmonizing animal husbandry and environmental restoration,while promoting sustainable development goals by 2030. | QU Yingbo ZHAO Yuanyuan DING Guodong CHI Wenfeng GAO Guanglei | 2021 | Journal of Arid Land2021,13,2: | 2 |
| 8 | Seven years of biochar amendment has a negligible effect on soil available P and a progressive effect on organic C in paddy soils显示文摘Little attention has been paid to how long-term application of crop straw and its biochar affects soil phosphorus(P)transformation and carbon(C)fractions.We conducted a 7-year field experiment including control treatment(chemical fertilizer only,CK),straw return(2.25 t ha^(−1)),and different amounts of biochar addition(11.25 t ha^(−1)(0.5%BC)and 22.5 t ha^(−1)(1.0%BC),to investigate influence of these amendments on soil C structure,P fractions,and their interaction with microorganisms.The 13C nuclear magnetic resonance and soil P sequence fractionation were applied to capture changes of soil C compositions and P pool.Compared to CK,straw and biochar amendments decreased alkyl C/O-alkyl C,which is conducive to increased soil organic C.The 0.5%BC and 1.0%BC treatments enhanced recalcitrant aromatic C by 69.0%and 131%,respectively.Compared to CK(101.2±33.32 mg kg^(−1)),the 0.5%BC and 1.0%BC treatments had a negligible effect on soil available P,while negative effects were observed in straw treatment(59.79±9.023 mg kg^(−1)).Straw and biochar amendments increased primary P and occluded P,whereas had negligible effect on organic P.Redundancy analysis and correlation analysis indi-cated that C compositions and P pool correlated to microbial community composition and enzyme activities,and aromatic C was the most related factor.Moreover,structural equation modeling indicated available P was most related to phosphatase activity and C composition.Our findings reveal the changes of soil P and C response under long-term crop straw and its biochar amendment,and can contribute toward improving understanding of the effect of biochar and straw return in future agriculture management. | Jiahui Yuan Yu Wang Xu Zhao Hao Chen Guanglei Chen Shenqiang Wang | 2022 | Biochar2022,4,1: | 1 |

| 11 | Semantic Region Estimation of Assistant Robot for the Elderly Long-Term Operation in Indoor Environment显示文摘In this work, in order to improve spatial recognition abilities for the long-term operation tasks of the assistant robot for the elderly, a novel approach of semantic region estimation is proposed. We define a novel graphbased semantic region descriptions, which are estimated in a dynamically fashion. We propose a two-level update algorithm, namely, Symbols update level and Regions update level. The algorithm firstly adopts particle filter to update weights of the symbols, and then use the Viterbi algorithm to estimate the region the robot stays in based on those weights, optimally. Experimental results demonstrate that our proposed approach can solve problems of the long-term operation and kidnapped robot problem. | Guanglei Huo Lijun Zhao Ke Wang Ruifeng Li | 2016 | China Communications2016,13,5: | 1 |
| 12 | Long-term biochar addition significantly decreases rice rhizosphere available phosphorus and its release risk to the environment显示文摘Phosphorus(P)availability,diffusion,and resupply processes can be altered by biochar addition in flooded rice rhizosphere,which controls the risk of P release to the environment.However,there are few in-situ investigations of these rhizospheric processes and effects.To explore the effects of biochar addition on soil P availability,high-resolution dialysis(HR-Peeper),diffusive gradients in thin films(DGT),and zymography techniques were used to provide direct evidence in the rice rhizosphere at the sub-millimeter scale.Long-term(9-years)field and greenhouse pot experiments demonstrated that biochar addition notably decreased the soluble/labile P and Fe concentrations in rice rhizosphere(vs.no biochar addition;CK)based on the results of Peeper,DGT,and two-dimensional imaging of labile P fluxes.DGT-induced fluxes in the soil/sediment(DIFS)model and sediment P release risk index(SPRRI)further indicated that biochar addition decreased the diffusion and resupply capacity of P from soil solid to the solution,thereby decreasing P release risk to the environment.These processes were dominated by Fe redox cycling and the hydrolysis of Al(hydro)oxides that greatly increased the unavailable P(Ca-P and residual-P).Additionally,greenhouse pot experiments(without additional biochar)showed that the previous long-term biochar addition significantly increased soil phosphatase activity,due to an adaptive-enhancing response to P decrease in the rhizosphere zone.The in-situ study on the biogeochemical reactions of P in the rice rhizosphere may provide a new and direct perspective to better evaluate the biochar addition and potential benefits to agricultural soils. | Hao Chen Jiahui Yuan Guanglei Chen Xu Zhao Shenqiang Wang Dengjun Wang Lei Wang Yujun Wang Yu Wang | 2022 | Biochar2022,4,1: | 1 |
| 13 | Responses of soil phosphorus pools accompanied with carbon composition and microorganism changes to phosphorus-input reduction in paddy soils显示文摘In rice-wheat rotation systems, changes in soil phosphorus(P) pools and microorganisms in rice-growing seasons have been studied;however, further investigations are required to test whether these indexes exhibit different responses in wheat-growing seasons. Additionally, such studies need to include potential variations in soil carbon(C) structure and microbial community composition. In this study, a long-term rice-wheat rotation P-input reduction experiment was conducted to observe the variations in soil P pools and C composition in the 7th wheat season and to investigate the responses of soil enzyme activity and microbial communities. Four P fertilization treatments were included in the experiment, i.e., P application for rice season only(PR), for wheat season only(PW), and for both rice and wheat seasons(PR+W) and no P application in either season(Pzero). Compared with PR+W treatment, Pzero treatment significantly decreased(P < 0.05) labile and stable P pools. Different P fertilization regimes altered soil microbial community composition and enzyme activity, whereas C composition did not vary. However, PW treatment resulted in relatively more O-alkyl-C than PR treatment and the highest number of microorganisms. Besides, the higher ratios of fungi/bacteria and Gram-positive bactetia/Gram-negative bactetia were related to labile C pools, particularly O-alkyl-C, as opposed to recalcitrant C. Our results clarified the status of soil P pools, C chemistry, and the response of microorganisms under dry-farming conditions in the P input-reduced rice-wheat rotation system. | Jiahui YUAN Lei WANG Hao CHEN Guanglei CHEN Shenqiang WANG Xu ZHAO Yu WANG | 2021 | Pedosphere2021,31,1: | 1 |

| 15 | Probiotic Escherichia coli Nissle 1917 protect chicks from damage caused by Salmonella enterica serovar Enteritidis colonization显示文摘As a foodborne pathogen of global importance,Salmonella enterica serovar Enteritidis(S.Enteritidis)is a threat to public health that is mainly spread by poultry products.Intestinal Enterobacteriaceae can inhibit the colonization of S.Enteritidis and are regarded as a potential antibiotic substitute.We investigated,in chicks,the anti-S.Enteritidis effects of Escherichia coli(E.coli)Nissle 1917,the most wellknown probiotic member of Enterobacteriaceae.Eighty 1-d-old healthy female AA broilers were randomly divided into 4 groups,with 20 in each group,namely the negative control(group P),the E.coli Nissle 1917-treated group(group N),the S.Enteritidis-infected group(group S)and the E.coli Nissle1917-treated and S.Enteritidis-infected group(group NS).From d 5 to 7,chicks in groups N and NS were orally gavaged once a day with E.coli Nissle 1917 and in groups P and S were administered the same volume of sterile PBS.At d 8,the chicks in groups S and NS were orally gavaged with S.Enteritidis and in groups P and N were administered the same volume of sterile PBS.Sampling was conducted 24 h after challenge.Results showed that gavage of E.coli Nissle 1917 reduced the spleen index,Salmonella loads,and inflammation(P<0.05).It improved intestinal morphology and intestinal barrier function(P<0.05).S.Enteritidis infection significantly reduced mRNA expression of angiotensin-converting enzyme 2(ACE2)and solute carrier family 6-member 19(SLC6A19)in the cecum and the content of Gly,Ser,Gln,and Trp in the serum(P<0.05).Pretreatment with E.coli Nissle 1917 yielded mRNA expression of ACE2and SLC6A19 in the cecum and levels of Gly,Ser,Gln,and Trp in the serum similar to that of uninfected chicks(P<0.05).Additionally,E.coli Nissle 1917 altered cecum microbiota composition and enriched the abundance of E.coli,Lactobacillales,and Lachnospiraceae.These findings reveal that the probiotic E.coli Nissle 1917 reduced S.Enteritidis infection and shows enormous potential as an alternative to antibiotics. | Shu Wu Qianyun Zhang Guanglei Cong Yunqi Xiao Yiru Shen Shan Zhang Wenchang Zhao Shourong Shi | 2023 | Animal Nutrition2023,,3: | 0 |
| 16 | Self-assembly tungsten selenide hybrid ternary MOF derived magnetic alloys via multi-polarization to boost microwave absorption显示文摘Confronted with severe electromagnetic wave pollution,the development of high-performance electromagnetic wave shielding or absorbing materials is an effective way to deal with it.Notably,double transition metal alloys and transition metal dichalcogenides have attracted extensive attention in electromagnetic wave absorption,but few reports have studied the effects of these two materials on electromagnetic wave absorption at the same time.In this work,cobalt-based alloy with magnetic loss mechanism was selected for composition optimization.The ternary metal-organic framework was prepared by the one-step method,and then CoCu/C was prepared by high temperature annealing.Finally,in the hydrothermal process,ultra-thin tungsten selenide nanosheets were coated on the surface of magnetic component,and the final polyhedral WSe_(2)/CoCu/C composites with multiple heterogeneous interfaces were obtained.The synergistic effect of dielectric and magnetic components optimizes impedance matching and allows more electromagnetic waves to enter the absorber.Subsequently,through the conduction loss of high conductivity graphitized carbon,interfacial polarization,and dipole polarization of heterogeneous interfaces between the components,the magnetic loss provided by CoCu alloy can work together to maximize the attenuation ability of electromagnetic waves.Exactly,the minimum reflection loss(RLmin)value of the composite reaches-53.43 dB when the matched thickness is 2.1 mm,while the maximum effective absorption bandwidth(EABmax)reaches 6.0 GHz at a thin thickness of 1.8 mm.This work provides some support and reference for the design of novel electromagnetic wave absorbing materials via the dielectric/magnetic loss synergistic mechanism. | Tianbao Zhao Tingting Zheng Di Lan Yan Zhang Zhengshuo Sun Chao Wang Zirui Jia Guanglei Wu | 2024 | Nano Research2024,17,3: | 0 |
| 17 | Three-dimensional macroscopic absorbents: From synergistic effects to advanced multifunctionalities显示文摘The accelerated arriving of 5G era has brought a new round of intelligent transformation which will completely emancipate smart terminal devices.While the subsequent deleterious effect of electromagnetic wave on electronic devices is increasingly serious,driving the growth of next-generation electromagnetic wave absorbents.As a tactful combination of components and structures,three-dimensional(3D)macroscopic absorbents with fascinating synergy afford exceptional electromagnetic wave absorption,and tremendous efforts have been devoted to this investigation.However,in terms of macroscopic absorbents and their synergistic effect,few reviews are proposed to comb the latest achievements and detailed synergy.This review article focuses on the synergistic effect of macro-architectured absorbents mainly including structure-induced synergy,structure-components synergy,and multiple-components induced synergy.And then the potential construction principles and strategies of macroscopic absorbents are combed.Significantly,the key information for structures and components manipulation including nano-micro design and components regulation is further dissected by critically selected cutting-edge 3D macroscopic absorbents.Moreover,a brief summary of multifunctional electromagnetic wave absorbents(EWAs)-based macroscopic structures is presented.Finally,the development prospects and challenges of these materials are discussed. | Shijie Zhang Di Lan Xingliang Chen Yueyuan Gu Junwen Ren Suxuan Du Shichang Cai Xiaomiao Zhao Zhiwei Zhao Guanglei Wu | 2024 | Nano Research2024,17,3: | 0 |
| 18 | Evaluation and Driving Force Analysis of Cultivated Land Quality in Black Soil Region of Northeast China显示文摘Cultivated land is an important natural resource to ensure food,ecological and economic security.The cultivated land quality evaluation(CQE)is greatly significant for protecting and managing cultivated land.In this study,320 counties in the black soil region of Northeast China(BSRNC)represent the research units used to construct the CQE system measuring the soil properties(SP),cultivated land productivity(CLP),ecological environment(EE)and social economy(SE).The total of 19 factors were selected to calculate the integrated fertility index(IFI)and divided into grades.Simultaneously,we used the coupling coordination degree model to comprehensively analyze the spatial pattern of the cultivated land quality(CLQ)in the BSRNC,and use the structural equation model(SEM)to analyze the driving mechanism.The results show the following:1)The CLQ of 262 counties in the BSRNC is in a state of coupling and coordination,and the coupling and coordination degree presents a spatial distribution pattern of‘high in the southwest and northeast,low in the northwest and southeast’.The coordinated development degree of 271 counties is between 0.4 and 0.6,which is in a transitional state between coordination and disorder.2)The CLQ in the BSRNC is generally good,with an average grade of 3.High-quality cultivated land accounts for 58.45%of all counties,middle-and upper-quality cultivated land accounts for 27.05%,and poor-quality cultivated land accounts for 14.49%.3)The SEM analysis shows that the SP,CLP,EE,and SE all influence the CLQ.Among them,the SP has the largest driving force on the CLQ,while the SE has the smallest driving force on it.The results confirm that the main factors affecting the evaluation results are crop productivity level,normalized difference vegetation index,ratio vegetation index,difference vegetation index,and organic carbon content.When implementing protection measures in counties with a low CLQ,considering a balanced coordination of multiple systems and reasonably controlling the quality degradation are important.This study provides the current situation and driving factors of the CLQ in the BSRNC and will play an important role in black soil governance and utilization. | WANG Mingchang LIU Xingnan LIU Ziwei WANG Fengyan LI Xiaoyan HOU Guanglei ZHAO Shijun | 2023 | Chinese Geographical Science2023,33,4: | 0 |
| 19 | Roadmap for rechargeable batteries:present and beyond显示文摘Rechargeable batteries currently hold the largest share of the electrochemical energy storage market,and they play a major role in the sustainable energy transition and industrial decarbonization to respond to global climate change.Due to the increased popularity of consumer electronics and electric vehicles,lithium-ion batteries have quickly become the most successful rechargeable batteries in the past three decades,yet growing demands in diversified application scenarios call for new types of rechargeable batteries.Tremendous efforts are made to developing the next-generation post-Li-ion rechargeable batteries,which include,but are not limited to solid-state batteries,lithium–sulfur batteries,sodium-/potassium-ion batteries,organic batteries,magnesium-/zinc-ion batteries,aqueous batteries and flow batteries.Despite the great achievements,challenges persist in precise understandings about the electrochemical reaction and charge transfer process,and optimal design of key materials and interfaces in a battery.This roadmap tends to provide an overview about the current research progress,key challenges and future prospects of various types of rechargeable batteries.New computational methods for materials development,and characterization techniques will also be discussed as they play an important role in battery research. | Sen Xin Xu Zhang Lin Wang Haijun Yu Xin Chang Yu-Ming Zhao Qinghai Meng Pan Xu Chen-Zi Zhao Jiahang Chen Huichao Lu Xirui Kong Jiulin Wang Kai Chen Gang Huang Xinbo Zhang Yu Su Yao Xiao Shu-Lei Chou Shilin Zhang Zaiping Guo Aobing Du Guanglei Cui Gaojing Yang Qing Zhao Liubing Dong Dong Zhou Feiyu Kang Hu Hong Chunyi Zhi Zhizhang Yuan Xianfeng Li Yifei Mo Yizhou Zhu Dongfang Yu Xincheng Lei Jianxiong Zhao Jiayi Wang Dong Su Yu-Guo Guo Qiang Zhang Jun Chen Li-Jun Wan | 2024 | Science China Chemistry2024,67,1: | 0 |
| 20 | Anti-corrosive Hybrid Electrolytes for Rechargeable Aqueous Zinc Batteries显示文摘Aqueous zinc(Zn)-metal cells with cost-effective components and high safety have long been a promising large-scale energy storage system,but Zn anodes are intrinsically unstable with common aqueous electrolytes,causing substantial underutilization of the theoretical capacity.In this work,we report a strictly neutral aqueous Zn electrolyte at a low cost by leveraging the dynamic hydrolysis equilibrium of a dual-salt Zn(Ac)2/NaAc(Ac:CH3COO−)formulation.With the pH regulation,the corrosion and hydrogen evolution encountered in Zn anodes can be suppressed significantly.This hybrid aqueous electrolyte not only enables dendrite-free Zn plating/stripping at a nearly 95%Coulombic efficiency[an increase of 24%compared to that of the single-salt 1 mol/L Zn(Ac)2 electrolyte],but also supports the reversible operation of Zn cells paired with either Na3V2(PO4)3 or iodine cathodes—the former delivers a high output voltage of 1.55 V with an energy level of 99.5 W·h/kg(based on the mass of the cathode),and the latter possesses a high specific capacity of 110.9 mA·h/g while yielding long-term cyclability(thousands of cycles).These findings open up a new avenue of modifying practical electrolytes having targeted properties to stabilize multivalent metal anodes. | WANG Jia QIU Huayu ZHAO Zhiming ZHANG Yuchen ZHAO Jingwen MA Yinglei LI Jiedong XING Min LI Guicun CUI Guanglei | 2021 | Chemical Research in Chinese Universities2021,37,2: | 0 |
