| 1 | Global leaf nitrogen and phosphorus stoichiometry and their scaling exponent显示文摘Leaf nitrogen(N) and phosphorus(P) concentrations constrain photosynthetic and metabolic processes,growth and the productivity of plants. Their stoichiometry and scaling relationships regulate the allocation of N and P from subcellular to organism, and even ecosystem levels, and are crucial to the modelling of plant growth and nutrient cycles in terrestrial ecosystems. Prior work has revealed a general biogeographic pattern of leaf N and P stoichiometric relationships and shown that leaf N scales roughly as two-thirds the power of P. However, determining whether and how leaf N and P stoichiometries, especially their scaling exponents, change with functional groups and environmental conditions requires further verification. In this study, we compiled a global data set and documented the global leaf N and P concentrations and the N:P ratios by functional group, climate zone and continent. The global overall mean leaf N and P concentrations were 18.9 mg g^(-1) and 1.2 mg g^(-1), respectively, with significantly higher concentrations in herbaceous than woody plants(21.72 mg g^(-1) vs. 18.22 mg g^(-1) for N; and 1.64 mg g^(-1) vs. 1.10 mg g^(-1) for P). Both leaf N and P showed higher concentrations at high latitudes than low latitudes. Among six continents, Europe had the highest N and P concentrations(20.79 and 1.54 mg g^(-1)) and Oceania had the smallest values(10.01 and 0.46 mg g^(-1)). These numerical values may be used as a basis for the comparison of other individual studies. Further, we found that the scaling exponent varied significantly across different functional groups,latitudinal zones, ecoregions and sites. The exponents of herbaceous and woody plants were 0.659 and0.705, respectively, with significant latitudinal patterns decreasing from tropical to temperate to boreal zones. At sites with a sample size ≥10, the values fluctuated from 0.366 to 1.928, with an average of 0.841.Several factors including the intrinsic attributes of different life forms, P-related growth rates and relative nutrient availability of soils likely account for the inconstant exponents of leaf N vs. P scaling relationships. | Di Tian Zhengbing Yan Karl J.Niklas Wenxuan Han Jens Kattge Peter B.Reich Yongkai Luo Yahan Chen Zhiyao Tang Huifeng Hu Ian J.Wright Bernhard Schmid Jingyun Fang | 2018 | National Science Review2018，5，5： | 24 |
| 2 | Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration. | Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen | 2019 | National Science Review2019，6，4： | 21 |
| 3 | Family-level leaf nitrogen and phosphorus stoichiometry of global terrestrial plants显示文摘Leaf nitrogen(N) and phosphorus(P) concentrations are critical for photosynthesis, growth, reproduction and other ecological processes of plants. Previous studies on large-scale biogeographic patterns of leaf N and P stoichiometric relationships were mostly conducted using data pooled across taxa, while family/genus-level analyses are rarely reported. Here, we examined global patterns of family-specific leaf N and P stoichiometry using a global data set of 12,716 paired leaf N and P records which includes 204 families, 1,305 genera, and 3,420 species. After determining the minimum size of samples(i.e., 35 records), we analyzed leaf N and P concentrations, N:P ratios and N^P scaling relationships of plants for 62 families with 11,440 records. The numeric values of leaf N and P stoichiometry varied significantly across families and showed diverse trends along gradients of mean annual temperature(MAT) and mean annual precipitation(MAP). The leaf N and P concentrations and N:P ratios of 62 families ranged from 6.11 to 30.30 mg g–1, 0.27 to 2.17 mg g–1, and 10.20 to 35.40, respectively. Approximately 1/3–1/2 of the families(22–35 of 62) showed a decrease in leaf N and P concentrations and N:P ratios with increasing MAT or MAP, while the remainder either did not show a significant trend or presented the opposite pattern. Family-specific leaf N^P scaling exponents did not converge to a certain empirical value, with a range of 0.307–0.991 for 54 out of 62 families which indicated a significant N^P scaling relationship. Our results for the first time revealed large variation in the family-level leaf N and P stoichiometry of global terrestrial plants and that the stoichiometric relationships for at least one-third of the families were not consistent with the global trends reported previously. The numeric values of the family-specific leaf N and P stoichiometry documented in the current study provide critical synthetic parameters for biogeographic modeling and for further studies on the physiological and ecological mechanisms underlying the nutrient use strategies of plants from different phylogenetic taxa. | Di Tian Zhengbing Yan Suhui Ma Yuehong Ding Yongkai Luo Yahan Chen Enzai Du Wenxuan Han Emoke Dalma Kovacs Haihua Shen Huifeng Hu Jens Kattge Bernhard Schmid Jingyun Fang | 2019 | Science China(Life Sciences)2019，62，8： | 7 |

| 5 | Strain glass transition in high damping Mn-22Cu-5Ni-2Fe alloy显示文摘It has been recognized that the high damping capacity of MnCu based alloys is closely related to the formation of elastic twins as a result of antiferromagnetic transition and martensitic transformation. However, the mechanism for these transitions in this kind of alloy has not been fully understood. For example, previous investigations ascribed the elastic modulus softening prior to martensitic transformation to antiferromagnetic or pre-martensitic transitions, although no convincing evidence was reported. In this paper, an intensive experimental study was made of the modulus softening and microstructural evolution in a typical high damping Mn-22Cu-5Ni-2 Fe alloy, and the evidence of strain glass transition was reported. Such a transition, characterized by a continuous formation of nano-martensite domains, is accompanied by a gradual frequency-dependent modulus softening over a broad temperature range prior to martensitic transformation. | Shiwen Hou Fangyu Qin Jingyun Han Wenlong Xiao Fengshuang Lu Xinqing Zhao | 2018 | Progress in Natural Science:Materials International2018，28，5： | 3 |
| 6 | A histological and biomechanical study of bone stress and bone remodeling around immediately loaded implants显示文摘Immediate loading(IL)increases the risk of marginal bone loss.The present study investigated the biomechanical response of peri-implant bone in rabbits after IL,aiming at optimizing load management.Ninety-six implants were installed bilaterally into femurs of 48 rabbits.Test implants on the left side created the maximal initial stress of 6.9 and 13.4 MPa in peri-implant bone and unloaded implants on the contralateral side were controls.Bone morphology and bone-implant interface strength were measured with histological examination and push-out testing during a 12-week observation period.Additionally,the animal data were incorporated into finite element(FE)models to calculate the bone stress distribution at different levels of osseointegration.Results showed that the stress was concentrated in the bone margin and the bone stress gradually decreased as osseointegration proceeded.A stress of about 2.0 MPa in peri-implant bone had a positive effect on new bone formation,osseointegration and bone-implant interface strength.Bone loss was observed in some specimens with stress exceeding 4.0 MPa.Data indicate that IL significantly increases bone stress during the early postoperative period,but the load-bearing capacity of peri-implant bone increases rapidly with an increase of bone-implant contact.Favorable bone responses may be continually promoted when the stress in peri-implant bone is maintained at a definite level.Accordingly,the progressive loading mode is recommended for IL implants. | HAN JingYun HOU JianXia ZHOU Gang WANG Chao FAN YuBo | 2014 | Science China(Life Sciences)2014，57，6： | 2 |

| 12 | Quantitative Assessment of the Relative Contributions of Climate and Human Factors to Net Primary Productivity in the Ili River Basin of China and Kazakhstan显示文摘It is necessary to quantitatively study the relationship between climate and human factors on net primary productivity(NPP)inorder to understand the driving mechanism of NPP and prevent desertification.This study investigated the spatial and temporal differentiation features of actual net primary productivity(ANPP)in the Ili River Basin,a transboundary river between China and Kazakhstan,as well as the proportional contributions of climate and human causes to ANPP variation.Additionally,we analyzed the pixel-scale relationship between ANPP and significant climatic parameters.ANPP in the Ili River Basin increased from 2001 to 2020 and was lower in the northeast and higher in the southwest;furthermore,it was distributed in a ring around the Tianshan Mountains.In the vegetation improvement zone,human activities were the dominant driving force,whereas in the degraded zone,climate change was the primary major driving force.The correlation coefficients of ANPP with precipitation and temperature were 0.322 and 0.098,respectively.In most areas,there was a positive relationship between vegetation change,temperature and precipitation.During 2001 to 2020,the basin’s climatic change trend was warm and humid,which promoted vegetation growth.One of the driving factors in the vegetation improvement area was moderate grazing by livestock. | LIU Liang GUAN Jingyun HAN Wanqiang JU Xifeng MU Chen ZHENG Jianghua | 2022 | Chinese Geographical Science2022，32，6： | 1 |

| 14 | Microstructure of ultrahigh carbon martensite显示文摘Recent experimental investigations suggest that the martensite formed by quenching carbon steels(0.2–1.26 mass %C) are composed of twins and nanoscale ω particles in twin boundaries, rather than carbon supersaturated uniform solutions. In order to probe the microstructure of the martensite with ultrahigh carbon content, a novel strategy is employed in the present study to obtain ultrahigh carbon martensite(approximate2.1 mass %C) by quenching ductile cast iron. The microstructure of the martensite was intensively characterized by high resolution transmitting electron microscopy. It is indicated that the microstructure of the ultrahigh carbon martensites is composed of ultrafine {112} < 111 >-type twins and high-density nano-scaled ω particles embedded in twin boundaries. These ω nanoparticles in twin boundaries could remarkably impede the deformation of the movement of the nanotwins in martensites, leading to poor ductility and strength of the quenched ductile cast iron. These findings not only reveal the substructures of ultrahigh carbon martensite, but also enhance the understanding of the mechanical behavior of high carbon steels and ductile cast irons. | Chao Wang Yulin Chen Jingyun Han Dehai Ping Xinqing Zhao | 2018 | Progress in Natural Science:Materials International2018，28，6： | 0 |
| 15 | Molecular Structural Evolution of Near-Infrared Cationic AggregationInduced Emission Luminogens:Preclinical Antimicrobial Pathogens Activities and Tissues Regeneration显示文摘Increasingly infectious diseases from microbial pathogens(including bacteria and fungi)threaten human health:a situation that has aroused public health concern around the world.Unfortunately,broad-spectrum antimicrobial agents for treatment resistance pathogens and molecular research on their antimicrobial mechanisms are still scarce.Thus,the development of smart agents against microbial infection for surmounting the above dilemmas is an urgent task.In this contribution,we have tactfully designed a family of flexible aggregation-induced emission luminogens(AIEgens)with various alkyl chain lengths and successfully optimized a cationic AIEgen TPA-S-C6-NMe_(3)^(+)based on the molecular relay strategy for killing both bacteria and fungi in vitro with desired results under white light irradiation,superior to traditional commercial photosensitizers including methylene blue,chlorin e6,and protoporphyrin IX.The cationic AIEgen TPA-S-C6-NMe_(3)^(+)was bound to microbial pathogens via electrostatic and hydrophobic forces and exerted antimicrobial efficacy due to the synergistic effect of alkyl chain length,reactive oxygen species(ROS)generation capability,and two positive charges.Remarkably,AIEgen TPA-S-C6-NMe_(3)^(+)also exhibited a striking antimicrobial activity in vivo,and promoted the generation of new blood vessels and fibroblasts in bacteria-infected tissues,which was beneficial for wound healing in mice.Overall,we expect that our work could provide a powerful tool against microbial pathogens to avoid infections and to promote tissues regeneration in clinical practice. | Haidong Li Liuwei Zhang Jingjing Han Dayeh Kim Heejeong Kim Jeongsun Ha Jingyun Wang Juyoung Yoon | 2022 | CCS Chemistry2022，4，2： | 0 |
| 16 | China's landscape in oncology drug research:perspectives from research collaboration networks显示文摘Objective:Better understanding of China's landscape in oncology drug research is of great significance for discovering anti-cancer drugs in future.This article differs from previous stuthes by focusing on Chinese oncology drug research communities in co-publication networks at the institutional level.Moreover,this research aims to explore structures and behaviors of relevant research units by thematic community analysis and to address policy recommendations.Methods:This research used social network analysis to define an institutions network and to identify a community network which is characterized by thematic content.Results:A total of 675 sample articles from 2008 through 2012 were retrieved from the Science Citation Index Expanded(SCIE) database of Web of Science,and top institutions and institutional pairs are highlighted for further discussion.Meanwhile,this study revealed that institutions based in the Chinese mainland are located in a relatively central position,Taiwan's institutions are closely assembled on the side,and Hong Kong's units located in the middle of the Chinese mainland's and Taiwan's.Spatial division and institutional hierarchy are still critical barriers to research collaboration in the field of anti-cancer drugs in China.In addition,the communities focusing on hot research areas show the higher nodal degree,whereas communities giving more attention to rare research subjects are relatively marginalized to the periphery of network.Conclusions:This paper offers policy recommendations to accelerate cross-regional cooperation,such as through developing information technology and increasing investment.The brokers should focus more on outreach to other institutions.Finally,participation in topics of common interest is conducive to improved efficiency in research and development(R&D) resource allocation. | Han You Jingyun Ni Michael Barber Thomas Scherngell Yuanjia Hu | 2015 | Chinese Journal of Cancer Research2015，27，2： | 0 |
| 17 | The fabrication of atomically thin-MoS_(2) based photoanodes for photoelectrochemical energy conversion and environment remediation:A review显示文摘Photoelectrochemical(PEC) technology has been proved a promising approach to solve the problems of energy shortages and environmental pollution damages.It can convert unlimited solar energy resources into energy forms needed by mankind.The development of highly efficient photoanodes is a key step in realizing the large-scale practical application of PEC systems.However,the development of PEC photoanodes has been severely hindered by the issues of easy recombination of photo-generated charge carriers,low photon-to-electron conversion efficiency,poor photo-corrosion resistance,and low catalytic activity.Therefore,constructing high-performance and stable photoanodes is an urgent research field to promote the progress of PEC technology.The atomically thin molybdenum disulfide(AT-MoS_(2)) with unique physical and chemical properties has been widely applied in the fabrication of PEC photoanodes.The AT-MoS_(2) based photoanodes have exhibited excellent PEC performance,which providing promising candidates for ideal PEC application.Here,we summarize the fundamental natures of MoS_(2) and present the research efforts in the preparation of AT-MoS_(2) based photoanodes.Strategies for the fabrication of high-efficient AT-MoS_(2) based photoanodes are emphasized to provide guidelines to advance emerging PEC photoanodes.Besides,perspectives for the development of more efficient AT-MoS_(2) based photoanodes are proposed. | Zexu Chi Jingyun Zhao Yi Zhang Han Yu Hongbing Yu | 2022 | Green Energy & Environment2022，7，3： | 0 |
