1Issues and solutions toward zinc anode in aqueous zinc-ion batteries: A mini review显示文摘Aqueous zinc-ion batteries(ZIBs)have been intensively investigated as potential energy storage devices on account of their low cost,environmental benignity,and intrinsically safe merits.With the exploitation of highperformance cathode materials,electrolyte systems,and in-depth mechanism investigation,the electrochemical performances of ZIBs have been greatly enhanced.However,there are still some challenges that need to be overcome before its commercialization.Among them,the obstinate dendrites,corrosion,and hydrogen evolution reaction(HER)on Zn anodes are critical issues that severely limit the practical applications of ZIBs.To address these issues,various strategies have been proposed,and tremendous progress has been achieved in the past few years.In this article,we analyze the origins and effects of the dendrites,corrosion,and HER on Zn anodes in neutral and mildly acid aqueous solutions at first.And then,a scientific understanding of the fundamental design principles and strategies to suppress these problems are emphasized.Apart from these,this article also puts forward some requirements for the practical applications of Zn anodes as well as several cost-effectivemodifying strategies.Finally,perspectives on the future development of Zn anodes in aqueous solutions are also briefly anticipated.This article provides pertinent insights into the challenges on anodes for the development of highperformance ZIBs,which will greatly contribute to their practical applications.Chunlin Xie Yihu Li Qi Wang Dan Sun Yougen Tang Haiyan Wang 2020Carbon Energy2020,2,4:15
2Combining CLUE-S and SWAT Models to Forecast Land Use Change and Non-point Source Pollution Impact at a Watershed Scale in Liaoning Province, China显示文摘Non-point source(NPS) pollution has become a major source of water pollution. A combination of models would provide the necessary direction and approaches designed to control NPS pollution through land use planning. In this study, NPS pollution load was simulated in urban planning, historic trends and ecological protection land use scenarios based on the Conversion of Land Use and its Effect at Small regional extent(CLUE-S) and Soil and Water Assessment Tool(SWAT) models applied to Hunhe-Taizi River Watershed, Liaoning Province, China. Total nitrogen(TN) and total phosphorus(TP) were chosen as NPS pollution indices. The results of models validation showed that CLUE-S and SWAT models were suitable in the study area. NPS pollution mainly came from dry farmland, paddy, rural and urban areas. The spatial distribution of TN and TP exhibited the same trend in 57 sub-catchments. The TN and TP had the highest NPS pollution load in the western and central plains, which concentrated the urban area and farm land. The NPS pollution load would increase in the urban planning and historic trends scenarios, and would be even higher in the urban planning scenario. However, the NPS pollution load decreased in the ecological protection scenario. The differences observed in the three scenarios indicated that land use had a degree of impact on NPS pollution, which showed that scientific and ecologically sound construction could effectively reduce the NPS pollution load in a watershed. This study provides a scientific method for conducting NPS pollution research at the watershed scale, a scientific basis for non-point source pollution control, and a reference for related policy making.LIU Miao LI Chunlin HU Yuanman SUN Fengyun XU Yanyan CHEN Tan 2014Chinese Geographical Science2014,24,5:15

4A New Species of Phoenicopsis Subgenus Windwardia(Florin) Samylina(Czekanowskiales) from the Middle Jurassic of Inner Mongolia, China显示文摘A new species of Phoenicopsis subgenus Windwardia(Florin) Samylina, Phoenicopsis neimengguensis sp.nov., is recognized from the Middle Jurassic Zhaogou Formation in the Shiguai Basin, a Jurassic coal-bearing sedimentary basin in Inner Mongolia, China. Linear leaves are in bundles of six to eight and are attached on a short shoot. The leaf is amphistomatic with one or two irregular rows of longitudinally oriented stomata in each intercostal zone on the upper epidermis and three or four(occasionally six) rows of stomata in each intercostal zone on the lower epidermis. Each stomata is surrounded by four to six subsidiary cells with unevenly developed papillae. The anticlinal walls of epidermal cells are straight. Cuticular thickenings or papillae are present on the outer surface of the periclinal walls. This is the first time that Phoenicopsis subgenus Windwardia(Florin) Samylina is recognized from the Middle Jurassic of Inner Mongolia, China. The occurrence of the new species is noteworthy because it extends the geological and geographic distribution of Phoenicopsis subg. Windwardia in China and Eurasia. The discovery is significant as it increases our knowledge of Phoenicopsis subg. Windwardia by providing new data on morphological and epidermal features.SUN Chunlin NA Yuling David L.DILCHER WANG Hongshan LI Tao LI Yunfeng 2015Acta Geologica Sinica(English Edition)2015,89,1:7

6Solenites (Czekanowskiales) from the Late Mesozoic Jehol Biota of Southeastern Jilin,China and its Paleoclimatic Implications显示文摘Situated at the easternmost area of the Late Mesozoic Jehol Biota, China, abundant fossils, including invertebrates, vertebrates and plants, were collected from the Early Cretaceous Yingzuilazi Formation of the Baishan Basin, southeastern Jilin. The faunal remains from this formation distinctly belong to the Early Cretaceous Lycoptera–Ephemeropsis–Eosestheria assemblage of the Jehol Biota. Based on the gross leaf morphology and epidermal structures, two new species and one indeterminate species of genus Solenites(Czekanowskiales), S. baishanensis sp. nov., S. gracilis sp. nov. and S. sp. are described in this paper. This is the first fossil plant of Czekanowskiales reported from this new fossil locality of the easternmost area of the Late Mesozoic Jehol Biota, China. The new discovery contributes to improve our knowledge for understanding of leaf morphology, epidermal characters and diversity of this genus during the Early Cretaceous time, and extends geologic and geographic distribution of Solenites in northern China and Eurasia. Along with consideration of associated plant and faunal assemblages and sedimentology, we suggest that the regional climate was warm and moderately humid with seasonal temperature and precipitation variations in warm–temperate zone during the Early Cretaceous.LI Yunfeng SUN Chunlin LI Tao NA Yuling CHEN Yuejun XING Dehe 2015Acta Geologica Sinica(English Edition)2015,89,4:5
7Effects of Boundary Conditions on the Design of Anti-Ram Bollards显示文摘Anti-ram bollards used in perimeter protection are tested to meet performance requirements of established standards such as the US Department of State Specification SD-STD-02.01. Under these standards, tests are conducted in prescribed conditions that should be representative of the service installation. In actual project, conditions encountered on site may vary from the test environment and it would be expensive and time consuming to validate each deviation with a physical test. High-fidelity physics-based (HFPB) finite element modeling can provide precise simulations of the behavior of anti-ram bollards. This paper presents the use of HFPB finite element modeling, using LS-DYNA, in an actual project to evaluate the performance of an anti-ram bollard design subjected to various boundary conditions representing the physical conditions encountered on site. The study shows that boundary conditions can have a significant influence on the performance of the anti-ram bollards. This suggests that anti-ram bollards must be designed and engineered according to actual conditions that are found on site. It also shows that HFPB modeling can be an effective tool that supplements physical testing of anti-ram bollards.LIU Chunlin LI Guoqiang PHANG Siew Kheong SUN Jianyun 2008Transactions of Tianjin University2008,14,5:3
8Dynamics of a deflectable-nose missile显示文摘The dynamics of a supersonic missile with a deflectable nose are studied. To describe the effects of nose deflection on the dynamic model, theorems of momentum and angular momentum are adopted to develop the translational equation and rotation equation, respectively. Because the exact model is complex, it is simplified. The simplified model suggests that the main influence of nose deflection on the dynamic model is due to the product of the time derivatives of the azimuth angle and the elevation angle, which makes the dynamic model an impulsive differential system. Considering the aerodynamic characteristics a numerical simulation is sufficient to show the open-loop characteristics of the missile.SUN XiaoFeng GU LiangXian GONG ChunLin 2012Science China(Technological Sciences)2012,55,12:3
9Anomozamites(Bennettitales) from Middle Jurassic Haifanggou Formation,western Liaoning,China显示文摘The Middle Jurassic Hangfanggou Formation is well exposed in Shangsanjiao and Xiasanjiao villages area,Baimashi town of Huludao,western Liaoning,China.Recently,abundant fossil plants were collected from the Hangfanggou Formation.One new species,Anomozamites sanjiaocunensis sp.nov.(Bennettitales),is described in this study.This is the first report of the genus Anomozamites from the Haifanggou Formation based upon the leaf morphology and epidermal structures.The discovery of the new species extends significantly the stratigraphic and geographic distribution of Anomozamites in the Middle Jurassic.It also shows that Anomozamites was a common member of Bennettitales once lived in the Middle Jurassic warm temperate region.The new species also improves the knowledge on understanding the leaf morphology,epidermal features and the diversity of Anomozamites during the Middle Jurassic.The epidermal characters of the new species and its associated plants reveal that the plants grew in a warm and moderately humid environment in the warm temperate zone.The presence of some deciduous plants,such as ginkgoaleans,czekanowskialeans and conifers,indicate the climate with seasonal fluctuations in temperature.ZHAO Miao SUN Chunlin David L.Dilcher ZHAO Zhe NA Yuling 2015Global Geology2015,18,2:3
10A prototype RF power source for CSNS/RCS显示文摘A prototype RF power source has been built to supply high RF power to a ferrite-loaded cavity, which is a part of R&D of the Rapid Cycling Synchrotron of China Spallation Neutron Source (CSNS/RCS). A direct fast RF feedback amplifier, a 4:1 impedance transformer and auto tuning grid were locally located to compensate the heavy beam loading of CSNS/RCS. Design and commissioning of the RF power source is discussed here, also with some advice on system improvement.WeiLing Huang (1) Hong Sun (1) HaiQi Zhao (2) Yu Liu (2) YanDong Li (2) ZhiGuang Qiao (2) Xiao Li (1) ChunLin Zhang (1) 2011Science China(Physics,Mechanics & Astronomy)2011,54,S2:3
11Discovery of Late Permian Jianshanzi volcanic rocks in Qinghe valley of northern Liaoning and its geologic significance显示文摘Jianshanzi volcanic rocks at Qinghe valley in the northern Liaoning were considered belonging to Early Proterozoic Gaojiayu Formation of Liaohe Group, or to Early Cambrian Beidagou Formation of Qinghezhen Group, or Middle-Late Proterozoic Shenjiapu Formation-Complex of Kaiyuan Group-complex. Dating the zircons from the dacite with schistosity is 2 506 Ma in method of U-Pb (SHRIMP). This evidence indicates the rocks may be referred to Late Permian in age. Discovery of the rocks is significant to re-recognize stratigraphic property of 'Liaohe Group', regional geotectonic location and revolution of orogenic zone in Qinghe valley of the northern Liaoning.Yuejun CHEN Chunlin SUN Yuewu SUN 2008Global Geology2008,11,3:2
12Flabellariopteris, a new aquatic fern leaf from the Late Triassic of western Liaoning, China显示文摘An aquatic fern leaf,Flabellariopteris mii Sun gen.et sp.nov.from the Late Triassic of Western Liaoning,China,is described and proposed as the type species of the new morphortaxon of the Marsileaceae.The fossil leaves are preserved as impression.No fertile and rhizomatic materials are found.The leaves attached at a common point on the top of the petiole are composed of two leaflets joined basally in an opposite arrangement.The petiole is slender.The leaflet is fan-shaped or semi-circular,and commonly divided into four wedge-shaped lobes.Terminal margin of lobes is usually incised,incisions shallow or deep,with bluntly rounded or notched apex.The veins are conspicuously dichotomous,but anastomoses and marginal vein are absent.The unique morphological features,including twoparted thin leaflets,size,shape,veins and slender petiole,indicate that the present specimen represents an aquatic fern,which is the oldest fossil record and the first megafossil evidence assignable to Marsileaceae from the Triassic floras.Chunlin Sun Tao Li Yuling Na Wenhao Wu Yunfeng Li Lixia Wang Lijun Zhang 2014Chinese Science Bulletin2014,59,20:2

15Sedimentological features of Cretaceous--Tertiary (K/T) boundary section along Heilongjiang River,Northeast China显示文摘The Jiayin area along the Heilongjiang River in Northeast China has attracted stratigraphic and sedimentological interests recently because the Cretaceous--Tertiary (K/T) boundary should be located in this non-marine succession.Dinosaur remains disappear suddenly at the upper part of the Maastrichtian,whereas plants gradually evolved throughout the succession.Analysis of sedimentary facies has been carried out and paleo-environments through Upper Cretaceous to lower Paleocene sections are reconstructed.Fluvial to lacustrine sedimentary environments are inferred from the facies.Several debris flow events have been identified,and it is in these deposits that the dinosaur fossils are concentrated.Shigeyuki Suzuki Hakuyu Okada SUN Chunlin SUN Ge 2010Global Geology2010,13,1:1
16Apoptosis-related protein expression in rabbits with blast brain injury following early hyperbaric oxygen therapy显示文摘We treated detonator-explosion-induced craniocerebral injury in rabbits with hyperbaric oxygen 1-24 hours post-injury.Expression of the apoptosis-regulating protein cytochrome c,the pro-apoptotic protein Bax and the apoptosis marker caspase-3 in the tissues surrounding the area of injury was significantly reduced,while that of the anti-apoptotic protein Bcl-2 was significantly increased.Our findings indicate that the curative effects of early hyperbaric oxygen on cortical cell apoptosis is associated with suppression of cytochrome c release from mitochondria.This mechanism underlies the observed reduction in Bax expression and upregulation of Bcl-2 expression.Shaonian Xu Jiachuan Liu Yongming Zhang Chunlin Wang Jinbiao Wang Yanyan Yang Jian Huo Wenjiang Sun 2012Neural Regeneration Research2012,7,17:1
17Early Jurassic Flora and Stratigraphy from Shansonggang of Southern Jilin,China显示文摘More than 35 species belonging to 22 genera of fossil plants are recognized by the authors from the Shan-songgang flora in the Shansonggang Basin of Jilin, China. Among them, the coexistence of Coniopteris and Cycadocarpi-dium demonstrates that the present flora possesses the characters of the early assemblage of Early Jurassic floras in Eura-sia. Therefore, the age of the Shansonggang flora is considered the Early Jurassic.This study would be beneficial for bet-ter understanding the paleoecological and paleoclimatic characteristics of the Shansonggang Basin. Based mainly on the characters of the flora, the authors suggest that the Lower Jurassic coal-bearing strata, the Shansongang Formation, should namely be renewed.Fengxiang Liu Yuewu Sun Chunlin Sun Jiansheng Lu Yanhua Zhao 2003Global Geology2003,8,1:1

19An introductory report on the biodiversity of Middle Jurassic Phoenicopsis(Czekanowskiales) from the Ordos Basin, China显示文摘Although the genus Phoenicopsis is the most common member of Czekanowskiales and is considered an indicative representative of the Middle Jurassic Coniopteris–Phoenicopsis assemblage in northern China, little was known about its taxonomy and biodiversity based upon the leaf cuticular structure. In this paper, three subgenera of the genus Phoenicopsis from the Middle Jurassic, Yan'an Formation of the Ordos Basin, China, Phoenicopsis(subg. Phoenicopsis)(Heer) Samylina, P.(subg. Windwardia)(Florin) Samylina and P.(subg. Culgoweria)(Florin) Samylina are identified based upon the leaf epidermal features for the first time. This discovery demonstrates that Phoenicopsis was quite diverse during the Middle Jurassic in northern China. Its biodiversity is significant for further understanding Middle Jurassic paleophytogeography and paleoclimatology of northern China. The current findings show that the three Phoenicopsis subgenera coexisted and flourished in the mixed zone(ecotone) between the Indo-Sinian Floristic Region and the Siberian Floristic Region as seasonal deciduous plants(trees or shrubs) during the Middle Jurassic. They were important elements in the Middle Jurassic deciduous gymnospermous forest community in warm temperate regions with seasonal temperature and precipitation variations. They are interpreted as growing on the hillsides and sloping fields along meandering streams, lakes and swamps in a vast sedimentary basin in a wet and warm environment.Chunlin Sun Yunfeng Li David L.Dilcher Hongshan Wang Tao Li Yuling Na Anping Wang 2015Science Bulletin2015,60,21:1
