| 1 | An electrochemical impedance spectroscopic study of the electronic and ionic transport properties of LiCoO_2 cathode显示文摘The storage behavior and process of the first delithiation-lithiation of LiCoO2 cathode were investigated by electrochemical impedance spectroscopy(EIS). The electronic and ionic transport properties of LiCoO2 cathode along with variation of electrode potential were obtained in 1 mol·L?1 LiPF6-EC:DMC:DEC electrolyte solution. It was found that after 9 h storage of the LiCoO2 cathode in electrolyte solu-tions,a new arc appears in the medium frequency range in Nyquist plots of EIS,which increases with increasing the storage time. In the charge/discharge processes,the diameter of the new arc is reversi-bly changed with electrode potential. Such variation coincides well with the electrode potential de-pendence of electronic conductivity of the LiCoO2. Thus this new EIS feature is attributed to the change of electronic conductivity of LixCoO2 during storage of the LiCoO2 cathode in electrolyte solutions,as well as in processes of intercalation-deintercalationtion of lithium ions. It has been revealed that the reversible increase and decrease of the resistance of SEI film in charge-discharge processes can be also ascribed to the variation of electronic conductance of active materials of the LiCoO2 cathode. | ZHUANG QuanChao XU JinMei FAN XiaoYong DONG QuanFeng JIANG YanXia HUANG Ling SUN ShiGang | 2007 | Chinese Science Bulletin2007，52，9： | 5 |
| 2 | Studies of the first lithiation of graphite materials by electrochemical impedance spectroscopy显示文摘First lithiation of graphite electrode in 1 mol/L LiPF6-EC:DEC:DMC electrolyte was investi- gated by electrochemical impedance spectroscopy (EIS). The results illustrated that the first arc in the high-frequency range observed in the Nyquist dia- gram appears near 0.9 V in the initial lithiation of graphite electrode, and its diameter increases with the decrease of polarization potential. These EIS features were attributed to the formation and growth of SEI film. Appropriate equivalent circuit was pro- posed to fit the experimental EIS data. The fitting results revealed the process of the formation and growth of SEI film, and evaluated quantitatively the resistance of charge transfer, as well as the capaci- tance of double layer along with the increase of po- larization potentials. | ZHUANG Quanchao CHEN Zuofeng DONG Quanfeng JIANG Yanxia HUANG Ling SUN Shigang | 2006 | Chinese Science Bulletin2006，51，9： | 3 |
| 3 | Sex-specific responses of tree-ring growth to climate in the dioecious tree Populus cathayana显示文摘Aims Radial growth in response to climate has been reported in many trees,but the sex-specific responses of tree-ring growth associated with altitude in dioecious trees are still poorly known.This study aims to examine whether(i)there are sex-related responses of tree-ring growth to climate in dioecious trees;(ii)these responses could be changed with altitude elevation.Methods The tree-ring width and basal area increment(BAI)were measured over the past 30 years(1982-2011),and the sexual differences in relationship between BAI and time span and correlations between ring width and climatic factors were investigated in Populus cathayana trees at two altitude sites(1,450 m and 1,750 m a.s.l.)in Xiaowutai Mountain,Hebei,north China.Important Findings The BAI was increased over the past 30 years.Trees at high-altitude sites had significantly lower mean ring width and mean BAI than those trees at low-altitude sites(P<0.001).In addition,sexual dif-ferences in tree-ring growth and its response to climate were more pronounced by altitude elevation.Male trees had a significantly larger mean ring width and mean BAI than did females at high-alti-tude sites,whereas no significant sexual differences in these traits were detected at low-altitude sites.Female trees were sensitive to previous October-November temperatures at high altitude but to current February and April precipitation at low altitude(P<0.05),whereas male trees were sensitive to current June temperature at high altitude but to January precipitation at low altitude(P<0.05).Our results indicated that the responses of tree-ring growth to cli-mate are sex dependent and can be changed with altitude elevation. | Kechao Huang Yongmei Liao Tingfa Dong Yanxia Yang Jundong He Huihui Huan Qibing Zhang Xiao Xu | 2018 | Journal of Plant Ecology2018，11，5： | 2 |

| 5 | A shedding soluble form of interleukin-17 receptor D exacerbates collagen-induced arthritis through facilitating TNF-α-dependent receptor clustering显示文摘Rheumatoid arthritis(RA)is exacerbated by TNF-alpha signaling.However,it remains unclear whether TNF-α-activated TNFR1 and TNFR2 are regulated by extracellular factors.Here,we showed that soluble glycosylated interleukin-17 receptor D(sIL-17RD),which was produced by proteolytic cleavage,enhanced TNF-α-induced RA.We revealed that IL-17RD shedding was induced by the proteolytic enzyme TACE and enhanced by TNF-αexpression in macrophages.Intriguingly,sIL-17RD was elevated in the sera of arthritic mice and rats.Recombinant sIL-17RD significantly enhanced the TNF-α-induced proinflammatory response by promoting TNF-α-TNFR-sIL-17RD complex formation and receptor clustering,leading to the accelerated development of collagen-induced arthritis.Our observations revealed that ectodomain shedding of IL-17RD occurred in RA to boost the TNF-α-induced inflammatory response.Targeting sIL-17RD may provide a new strategy for the therapy of RA. | Sihan Liu Yanxia Fu Kunrong Mei Yinan Jiang Xiaojun Sun Yinyin Wang Fangli Ren Congshan Jiang Liesu Meng Shemin Lu Zhihai Qin Chen Dong Xinquan Wang Zhijie Chang Shigao Yang | 2021 | Cellular & Molecular Immunology2021，18，8： | 1 |

| 9 | Emergy evaluation of the artificial forest ecosystems in the watershed of Miyun Reservoir:a case study for ecosystems valuation and environmental management显示文摘To build the artificial forest ecosystem is the major eco-economic development model in the watershed of Miyun Reservoir. It is very important to evaluate the benefits of those ecosystems. Emergy theories are very helpful for us to establish a science-based assessment framework. Emergy evaluation of the artificial forest ecosystems in the watershed of Miyun Reservoir is used to asses the relative values of several ecological functions (sometimes called ecosystem services) and main ecosystem storages (sometimes called natural capital). The main driving energies, internal processes and storages are evaluated. The main functions, including transpiration, GPP and infiltration, are evaluated, which are 609em$/ha/yr, 6,245em$/ha/yr and 340em$/ha/yr respectively. The total values of major environmental services are 4,683em$/ha/yr in the artificial forest ecosystem. The main storages of natural capital including live biomass, soil moisture, organic matter, underground water and landform are estimated, which are 112,028em$/ha, 9em$/ha, 40,718em$/ha, 34em$/ha and 6,400,514em$/ha respectively. The largest value is landform, which accounts for 97.7% of these calculated total emdollar values. The concept of replacement value is explored using the emergy values of both ecosystem services and natural capital. The total calculated replacement values are 302,160em$/ha. | Hu Yanxia Zhou Liandi Dong Xiaobin Yan Maochao | 2007 | Ecological Economy2007，3，4： | 1 |

| 11 | Genome-wide association study reveals candidate genes for gummy stem blight resistance in cucumber显示文摘Gummy stem blight(GSB),caused by Didymella bryoniae,is a serious fungal disease that leads to decline in cucumber yield and quality.The molecular mechanism of GSB resistance in cucumber remains unclear.Here,we investigated the GSB resistance of cucumber core germplasms from four geographic groups at the seedling and adult stages.A total of 9 SNPs related to GSB resistance at the seedling stage and 26 SNPs at the adult stage were identified,of which some are co-localized to previously mapped Quantitative trait loci(QTLs)for GSB resistance(gsb3.2/gsb3.3,gsb5.1,and gsb-s6.2).Based on haplotype analysis and expression levels after inoculation,four candidate genes were identified within the region identified by both Genome-wide association study(GWAS)and previous identified QTL mapping,including Csa3G129470 for gsb3.2/gsb3.3,Csa5G606820 and Csa5G606850 for gsb5.1,and Csa6G079730 for gsb-s6.2.The novel GSB resistant accessions,significant SNPs,and candidate genes facilitate the breeding of GSB resistant cucumber cultivars and provide a novel idea for understanding GSB resistance mechanism in cucumber. | Jianan Han Shaoyun Dong Yanxia Shi Zhuonan Dai Han Miao Baoju Li Xingfang Gu Shengping Zhang | 2023 | Horticultural Plant Journal2023，9，2： | 1 |

| 14 | Exploring the mechanism of Ta_(3)N_(5)/KTaO_(3) photocatalyst for overall water splitting by first-principles calculations显示文摘The rational fabrication of heterostructures is one of efficient strategies for improving photocatalytic performance of semiconductor photocatalysts.Very recently,Domen and co-workers found that Ta_(3)N_(5) single crystals grown on the surface of KTaO_(3) can accomplish photocatalytic overall water splitting for the first time.In order to comprehend the underlying mechanism of this photocatalytic system,we have performed a systematic study based on density functional theory first-principles calculations.Ta_(3)N_(5)(010)/KTaO_(3)(110)slab models have been built according to experimental observations by considering two common terminations of KTaO_(3)(110)surface,named as Ta_(3)N_(5)/O_(2) and Ta_(3)N_(5)/KTaO.The formations of interfacial bonds are thermodynamically stable,showing a covalent interaction between two components of a heterostructure.Ta_(3)N_(5)/O_(2) has a higher mobility of photogenerated charge carriers and lower recombination rate of charge carriers than Ta_(3)N_(5)/KTaO.The light absorption of heterostructures displays the feature of KTaO_(3) in the short wavelength region and the characteristic of Ta_(3)N_(5) in the long wavelength region.The calculated band offsets show that Ta_(3)N_(5)/O_(2) and Ta_(3)N_(5)/KTaO have distinct Type-II band alignments,with Ta_(3)N_(5) as the accumulator of photoinduced electrons in the former and the collector of photogenerated holes in the latter,respectively.The difference in charge density and electrostatic potential between two components acts as a driving force to promote the transfer of electrons and holes to different domains of the interface,which is beneficial to extend the lifetime of photoinduced carriers.Our results demonstrate that the function of Ta_(3)N_(5) in Ta_(3)N_(5)/KTaO_(3) photocatalytic system is determined by the termination property of KTaO_(3)(110)surface,which provides a likely reason of the observed photocatalytic activity of overall water splitting achieved by Ta_(3)N_(5) synthesized by using KTaO_(3) as a precursor for the nitridation reaction. | Yanxia Ma Yumeng Fo Miaomiao Wang Xixi Liang Hao Dong Xin Zhou | 2021 | Journal of Energy Chemistry2021，30，5： | 0 |
| 15 | Enhanced cross-flow filtration with flat-sheet ceramic membranes by titanium-based coagulation for membrane fouling control显示文摘Application of ceramic membrane(CM)with outstanding characteristics,such as high flux and chemical-resistance,is inevitably restricted by membrane fouling.Coagulation was an economical and effective technology for membrane fouling control.This study investigated the filtration performance of ceramic membrane enhanced by the emerging titanium-based coagulant(polytitanium chloride,PTC).Particular attention was paid to the simulation of ceramic membrane fouling using four widely used mathematical models.Results show that filtration of the PTC-coagulated effluent using flat-sheet ceramic membrane achieved the removal of organic matter up to 78.0%.Permeate flux of ceramic membrane filtration reached 600 L/(m2$h),which was 10-fold higher than that observed with conventional polyaluminum chloride(PAC)case.For PTC,fouling of the ceramic membrane was attributed to the formation of cake layer,whereas for PAC,standard filtration/intermediate filtration(blocking of membrane pores)was also a key fouling mechanism.To sum up,cross-flow filtration with flat-sheet ceramic membranes could be significantly enhanced by titanium-based coagulation to produce both high-quality filtrate and high-permeation flux. | Xiaoman Liu Chang Tian Yanxia Zhao Weiying Xu Dehua Dong Kaimin Shih Tao Yan Wen Song | 2022 | Frontiers of Environmental Science & Engineering2022，16，8： | 0 |
| 16 | Preparation and characteriza-tion of a novel composite mi-croporous polymer electrolyte for Li-ion batteries显示文摘A novel composite microporous polymer elec- trolyte composed of poly(vinylidene fluoride-co-hexafluorop- ropylene) (PVdF-HFP) and mesoporous SBA-15 was pre- pared. The composite solid polymer electrolyte (CSPE) ex- hibits ionic conductivity as high as 0.30 mS·cm?1 with a composition of SBA-15︰PVdF-HFP=3︰8 at room tem- perature. Infrared transmission spectroscopic results sug- gested that the mechanism of micropore formation is similar to that of the phase inversion. X-ray diffraction (XRD) results demonstrated that the addition of SBA-15 inhibits the crys- tallization of PVdF-HFP, while the SBA-15 preserves well its ordered mesoporous structure during the course of prepara- tion. The Li/CSPE/MCF of half-cell was assembled, and it showed a good electrochemical and cyclability performance during charge-discharge cycles. | CHEN Zuofeng JIANG Yanxia ZHUANG Quanchao DONG Quanfeng WANG Ye SUN Shigang | 2005 | Chinese Science Bulletin2005，50，14： | 0 |
| 17 | Boosted photocatalytic efficiency of GQDs sensitized(BiO)_(2)CO_(3)/β-Bi_(2)O_(3)heterojunction via enhanced interfacial charge transfer显示文摘The NO gas is easily oxidized to form toxic by-products(NO_(2))during the oxidation process,which are adsorbed on the catalyst surface and inhibit the subsequent reaction.For photocatalytic NO removal,a significant challenge is to achieve catalytic stability while maintaining high conversion efficiency.Here,we fabricated a(BiO)_(2)CO_(3)/β-Bi_(2)O_(3)heterostructure that enables efficient charge transfer and promotes the NO removal.We propose that the catalytic stability depends on the heterojunction structure,which is able to generate interfacial charge transfer channels.In addition,we further introduce graphene quantum dots on the heterojunction structure,which further strengthens the interfacial charge transfer dynamics and finally realizes that the NO_(2)byproduct could gain electrons and convert to the final product(nitrite or nitrate).This composite structure not only exhibits high activity for NO removal but also maintains long-term stability under visible light. | Yanxia Wang Jianping Sheng Xiaoli Zhao Ye He Fan Dong Yanjuan Sun | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
| 18 | Influence of Metal Material Properties on Heat and Mass Transfer into Thermal Protection Surface with Phenomenological Catalytic Model显示文摘Surface heterogeneous catalysis in a high-enthalpy dissociated environment leads to a remarkable enhancement of aerodynamic heating into the thermal protection surface of hypersonic aircraft.To more accurately predict this catalytic heating,a kinetic catalytic model was constructed.This model involved four elementary reactions,the rates of which were determined on mean-field approximation and surface steady-state reaction assumption.By coupling this model into the viscous wall boundary condition of computational fluid dynamics(CFD)solver,the influences of metal material catalytic properties on heat and mass transfer into thermal protection materials were numerically investigated.Numerical results showed that atomic oxygen recombination catalyzed by surface material accounts for a major contribution to aerodynamic heating and thus variation in recombination rates from different materials leads to the significant difference in surface heat fluxes.From a comparative analysis of various materials,the catalytic activity increases from the inert platinum(Pt)to nickel(Ni)and finally to the active copper(Cu).As a result,the catalytic heating on Cu surface was more than twice of that on Pt surface.Further parametrical research revealed that the proper layout of inert material at the nose of aircraft could prevent stagnation catalytic heating from thermal damage by carrying near-wall dissociated atoms from the stagnation zone downstream.The material-relied heterogeneous catalysis mechanism in this study provides some technical support for the thermal protection system design of hypersonic aircraft. | LI Qin YANG Xiaofeng DONG Wei DU Yanxia | 2023 | Journal of Thermal Science2023，32，3： | 0 |
| 19 | Genomic convergence underlying high-altitude adaptation in alpine plants显示文摘Evolutionary convergence is one of the most striking examples of adaptation driven by natural selection.However, genomic evidence for convergent adaptation to extreme environments remains scarce.Here, we assembled reference genomes of two alpine plants, Saussurea obvallata(Asteraceae)and Rheum alexandrae(Polygonaceae), with 37,938 and 61,463 annotated protein-coding genes. By integrating an additional five alpine genomes,we elucidated genomic convergence underlying high-altitude adaptation in alpine plants. Our results detected convergent contractions of diseaseresistance genes in alpine genomes, which might be an energy-saving strategy for surviving in hostile environments with only a few pathogens present.We identified signatures of positive selection on a set of genes involved in reproduction and respiration(e.g., MMD1, NBS1, and HPR), and revealed signatures of molecular convergence on genes involved in self-incompatibility, cell wall modification,DNA repair and stress resistance, which may underlie adaptation to extreme cold, high ultraviolet radiation and hypoxia environments. Incorporating transcriptomic data, we further demonstrated that genes associated with cuticular wax and flavonoid biosynthetic pathways exhibit higher expression levels in leafy bracts, shedding light on the genetic mechanisms of the adaptive “greenhouse” morphology. Our integrative data provide novel insights into convergent evolution at a high-taxonomic level,aiding in a deep understanding of genetic adaptation to complex environments. | Xu Zhang Tianhui Kuang Wenlin Dong Zhihao Qian Huajie Zhang Jacob BLandis Tao Feng Lijuan Li Yanxia Sun Jinling Huang Tao Deng Hengchang Wang Hang Sun | 2023 | Journal of Integrative Plant Biology2023，65，7： | 0 |
| 20 | Space Weather Service for Chinese Space Science Satellites显示文摘Strategic Priority Research Program on Space Science has gained remarkable achievements. Space Environment Prediction Center(SEPC) affiliated with the National Space Science Center(NSSC) has been providing space weather services and helps secure space missions. Presently, SEPC is capable to offer a variety of space weather services covering many phases of space science missions including planning, design, launch,and orbital operation. The service packages consist of space weather forecasts, warnings, and effect analysis that can be utilized to avoid potential space weather hazard or reduce the damage caused by space storms,space radiation exposure for example. Extensive solar storms that occurred over Chinese Ghost Festival(CGF)in September 2017 led to a large enhancement of the solar energetic particle flux at 1 AU, which affected the near Earth radiation environment and brought great threat to orbiting satellites. Based on the space weather service by SEPC, satellite ground support groups collaborating with the space Tracking, Telemetering and Command system(TT&C) team were able to take immediate measures to react to the CGF solar storm event. | LIU Siqing ZHONG Qiuzhen GONG Jiancun SHI Liqin CHEN Dong MIAO Juan CAI Yanxia BAI Meng MA Wenzhen LI Zhitao LIU Fanghua CHEN Yanhong | 2018 | 空间科学学报2018，38，5： | 0 |
