| 1 | The crustal structures of the central Longmenshan along and its margins as related to the seismotectonics of the 2008 Wenchuan Earthquake显示文摘In 2010,a 500-km-long wide-angle reflection/refraction seismic profile was completed,running northwest from the central Sichuan Basin.This profile orthogonally crosses the meizoseismal area of great Wenchuan earthquake of 12 May 2008,which occurred in the central part of the Longmenshan.The profile also passes through the northwestern Sichuan Plateau,along which a new deep seismic sounding observation system was set up that was much improved over previous datasets and enabled abundant observations to be recorded.Seismic wave phase records that reflect the structural characteristics of different tectonic blocks,especially the complicated phase features associated with the Wenchuan earthquake,were calculated and analyzed in detail.A 2D crustal P-wave velocity model for the orogenic belt in the central Longmenshan and its margins was determined,and crustal structure differences between the stable Sichuan Basin and the thickened northwestern Sichuan Plateau were characterized.Lithological variations within the upper and lower crust in the interior of the plateau,especially a great velocity decrease and plastic rheological properties associated with strong lithologic weakening in lower crust,were detected.From west to east in the lower crust beneath the orogenic belt lying between the Sichuan Basin and the northwestern Sichuan Plateau,a giant shovel-like upwelling is observed that dips gently in the lower part and at higher angles in the upper part;this is inferred to be related to the fault systems in the central Longmenshan.An upwelling in the upper-middle crust along the eastern margin of the orogenic belt is associated with steeply dipping thrusts that strongly uplift the upper crust and crystalline basement beneath a central fault system in the Longmenshan.The data,combined with an understanding of the regional tectonic stress field and previous geological results,enable a discussion of basin-and-range coupling,orogenic tectonics,the crustal fault system,and the seismogenic tectonic environment of the central Longmenshan along the eastern margin of the Qinghai-Tibet Plateau. | JIA ShiXu LIU BaoJin XU ZhaoFan LIU Zhi FENG ShaoYing ZHANG JianShi LIN JieYan TIAN XiaoFeng LIU QiaoXia GUO WenBin | 2014 | Science China Earth Sciences2014，57，4： | 26 |
| 2 | The P-wave velocity structure of the lithosphere of the North China Craton——Results from the Wendeng-Alxa Left Banner deep seismic sounding profile显示文摘For the first time on the Chinese mainland, long-range wide-angle seismic reflection/refraction profiling technology has been applied to seismic wave phases from different depths and with different attributes within the various blocks of the North China Craton to characterize the structure of the crust and upper mantle lithosphere. By comparative analysis of the seismic wave phase characteristics in each block across a 1500-km-long east-west profile, we have identified conventional Pg, Pci, PmP and Pn phases in the crust, made a clear contrast between PL1 and PL2 waves belonging to two groups of lithospheric-scale phases, and produced a model of crust-mantle velocity structures and tectonic characteristics after one- and two-dimensional calculations and processing. The results show that the thickness of the crust and lithosphere gradually deepens from east to west along the profile. However, at the reflection/refraction interface, seismic waves in each group show obvious localized changes in each block. Also, the depth to the crystalline basement changes greatly, from as much as 7.8 km in the North China fault basin to only about 2 km beneath the Jiaodong Peninsula and Taihang-Lüliang area. The Moho morphology as a whole ranges from shallow in the east to deep in the west, with the deepest point in the Ordos Block at 47 km; in contrast, the North China Plain Block is uplifting. The L1 interface of the lithosphere is observed only to the west of Taihang Mountains, at a relatively slowly changing depth of about 80 km. The L2 interface varies from 75 to 160 km and shows a sharp deepening to the west of Taihang Mountains, forming a mutation belt. | WANG ShuaiJun WANG FuYun ZHANG JianShi JIA ShiXu ZHANG ChengKe ZHAO JinRen LIU BaoFeng | 2014 | Science China Earth Sciences2014，57，9： | 26 |
| 3 | Community structure and composition of the Cambrian Chengjiang biota显示文摘Based on previously published species data(228 species in over 18 phyla) and field sampling(114 species and 18406 individuals) in the Chengjiang-Haikou-Anning area,we analyzed quantitatively the paleocommunity composition and structure of the Cambrian Chengjiang biota(Cambrian Series 2,eastern Yunnan,China).Arthropods dominate the community both in species diversity(species:37%) and in abundance(individuals:51.8%).Priapulids(individuals:22.6%) and brachiopods(individuals:16.3%) follow in abundance rank.The arthropod Kunmingella douvillei(26.2%),the priapulid Cricocosmia jinning-ensis(15.4%),and the brachiopod Diandongia pista(11%) are the three most abundant species.Ecological analyses show that the community was dominated by epifaunal organisms(species:63%,individuals:68.4%) followed by infaunal organisms(species:11.9%,individuals:25.9%),nektobenthic organisms(species:11.5%,individuals:2.6%),and pelagic organisms(species:5.3%,individuals:3.1%).The diverse feeding strategies,dominated by suspension feeders(species:35.6%,individuals:26.1%) and hunter/scavengers(species:31.1%,individuals:40.4%),indicate the former existence of a complex food chain and intense competition.Epifaunal vagrant omnivores(28.2%),infaunal vagrant hunter/scavengers(19.8%),epifaunal sessile suspension feeders(17.7%),and epifaunal vagrant hunter/scavengers(15.3%) were the most abundant ecological groups,represented primarily by arthropods,poriferans,priapulids,and brachiopods.Ecological group analyses reveal that the early Cambrian Chengjiang biota is similar in community patterns and functional relations to modern biotas in shallow marine settings. | ZHAO FangChen ZHU MaoYan HU ShiXue | 2010 | Science China Earth Sciences2010，53，12： | 14 |
| 4 | Eocrinoid echinoderms from the Lower Cambrian Guanshan Fauna in Wuding,Yunnan,China显示文摘This is a brief report of a new occurrence of eocrinoids from the Early Cambrian Wulongqing Formation in Yunnan, China. The eocrinoids from the Guanshan fauna are among the earliest known eocrinoids. Different from many other Early and Middle Cambrian eocrinoids, the Guanshan eocrinoids are char-acterized by the absence of sutural pores and epispires, the long and spiral brachioles, the extremely long stalk, and the ratio of the length of the stalk versus that of the calyx. The discovery of the eocri-noids from the Guanshan fauna not only provides new information to the investigation of the early evolution of this animal group, but also shed new light on the occurrence and migration of early eocrinoids. | HU ShiXue LUO HuiLin HOU ShuGuang Bernd-Dietrich ERDTMANN | 2007 | Chinese Science Bulletin2007，52，5： | 13 |
| 5 | New Early Cambrian Chordates from Haikou, Kunming显示文摘Two new chordates, Cathaymyrus haikouensis Luo et Hu sp. nov. andZhongxiniscus intermedius Luo et Hu gen. et sp. nov. are studied in this paper. Both display numerous S-shaped myomeres on their trunk. C. haikouensis shows a long and slim body similar to that of Cathaymyrus diadexus Shu et al., Zhongxiniscus approaches to Myllokunmingia and Haikouichthvs in the dorsal fin, but differs in the myomeres. Zhongxiniscus may be the intermediate form between Ca thaymyrus and Myllokunmingia and Haikouichthys. | LUO Huilin, HU Shixue and CHEN Liangzhong Yunnan Institute of Geological Sciences, 131 Baita Road, Kunming 650011, Yunnan | 2001 | Acta Geologica Sinica(English Edition)2001，75，4： | 12 |
| 6 | Deep seismic sounding data reveal the crustal structures beneath Zoigê basin and its surrounding folded orogenic belts显示文摘Songpan-Garze massif is located at the turning position of tectonics from the nearly west-east direction to the nearly north-south direction in the northeastern margin of Tibetan Plateau,with Zoigê basin in the centre of the massif.In this paper,we build a crustal structure model of Zoigê basin and its surrounding folded orogenic belts using the deep seismic sounding data in this region.We also discuss structures and properties of the basement in Zoigê basin,tectonic relations between Zoigê upland basin and its surrounding folded orogenic belts,crustal deformation and thickening in the northeastern margin of Tibetan Plateau,and decoupling and relaxing processes in the crust.The results indicate that a special 'Mesozoic basement' is formed of Triassic rocks with high density (2.65-2.75 g/cm3) and high velocity (5.6 km/s) in Zoigê basin.Songpan-Garze tectonic massif was transformed into two types of tectonic units with different crustal structures,i.e.,relatively stable Zoigê upland basin and active folded orogenic belts around the basin,in the course of the crustal material of Tibetan Plateau flowing eastward and obstructed by surrounding stable blocks.The thickening of the crust in the northeastern margin of Tibetan Plateau mainly occurred in the mid and lower crust,and the structure characterized by low velocities and multiple reflectors obviously appears in the folded orogenic belts around Zoigê basin.It implies that the mid and lower crust underwent a strong tectonic deformation in the folded orogenic areas.The thickness of the crust is about 50 km in Zoigê basin and the folded orogenic belts at the both southern and northern sides of Zoigê basin.The 'Mountain root' cannot be identified.It is inferred that during the later orogenic period the eastwards flowing deep materials moved clockwise along the relatively relaxing southern side around the eastern tectonic knot under the obstructing of surrounding rigid massifs,and it resulted in the strong stretching action of the folded orogenic belts around Zoigê basin. | JIA ShiXu,ZHANG XianKang,ZHAO JinRen,WANG FuYun,ZHANG ChengKe,XU ZhaoFan,PAN JiShun,LIU Zhi,PAN SuZhen & SUN GuoWei Geophysical Exploration Center,China Earthquake Administration,Zhengzhou 450002,China | 2010 | Science China Earth Sciences2010，53，2： | 11 |
| 7 | Mitochondria Play a Role in the Development of Non-Apoptotic Programmed Cell Death of Neutrophils Induced by ONO-AE-248显示文摘We previously reported that ONO-AE-248,a selective EP3 receptor agonist,has been shown to cause neutrophil death without the typical features of apoptosis and necrosis.However,the mechanism of the neutrophil death is unclear.By using Western blotting,flow cytometry(FACS)and confocal laser scanning microscopy(CLSM),we investigated the cellular signal transduction pathways of the neutrophil death.The research results showed that the neutrophil death induced by ONO-AE-248 did not show the morphologic changes of apoptosis and was not associated with the activity of caspase-3,caspase-8,and phosphorylation of p38-MAPK.However,impairment of mitochondria transmembrane potential has been found during the process of cell death.These findings suggested that ONO-AE-248 induced a non-apoptotic programmed cell death of neutrophils through partially mitochondria signaling transduction pathway. | Jiajia Liu Hao He Zi Zhang Shixu Jiang Tohru Akahoshi Jian Yang Juan Li Tao He | 2007 | Cellular & Molecular Immunology2007，4，6： | 11 |

| 10 | Recent progress in thermoelectric materials显示文摘Direct conversion of heat into electricity through advanced thermoelectric(TE)materials has been one of the most attractive solutions to the severe environmental and energy issues facing humanity.In recent years,great progress has been made in improving their dimensionless figure of merit(ZT),which determines the conversion efficiency of TE devices.ZT is related to three‘‘interlocked’’factors—the Seebeck coefficient,electrical conductivity,and thermal conductivity.These three factors are interdependent in bulk TE materials,and altering one changes the other two.The difficulty in simultaneously optimizing them caused TE research to stagnate,until great reductions in thermal conductivity were both theoretically and experimentally proven in nanomaterials in 1993.In this review,we first introduce some TE fundamentals and then review the most recently improvements in ZT in different kinds of inorganic and organic TE materials,which is followed by an investigation of the outlook for new directions in TE technology. | Chao Han Zhen Li Shixue Dou | 2014 | Chinese Science Bulletin2014，59，18： | 9 |

| 12 | Confining MOF-derived SnSe nanoplatelets in nitrogen-doped graphene cages via direct CVD for durable sodium ion storage显示文摘Tin-based compounds are deemed as suitable anode candidates affording promising sodium-ion storages for rechargeable batteries andhybrid capacitors.However,synergistically tailoring the electrical conductivity and structural stability of tin-based anodes to attain durablesodium-ion storages remains challenging to date for its practical applications.Herein,metal-organic framework(MOF)derived SnSe/C wrappedwithin nitrogen-doped graphene(NG@SnSe/C)is designed targeting durable sodium-ion storage.NG@SnSe/C possesses favorable electricalconductivity and structure stability due to the'inner'carbon framework from the MOF thermal treatment and'outer'graphitic cage from thedirect chemical vapor deposition synthesis.Consequently,NG@SnSe/C electrode can obtain a high reversible capacity of 650 mAh·g^-1 at 0.05 A·g^1,a favorable rate performance of 287.8 mAh·g^1 at 5 A·g^1 and a superior cycle stability with a negligible capacity decay of 0.016%percycle over 3,200 cycles at 0.4 A·g^1.Theoretical calculations reveal that the nitrogen-doping in graphene can stabilize the NG@SnSe/Cstructure and improve the electrical conductivity.The reversible Na-ion storage mechanism of SnSe is further investigated by in-situ X-raydiffraction/ex-s/tu transmission electron microscopy.Furthermore,assembled sodium-ion hybrid capacitor full-cells comprising our NG@SnSe/Canode and an active carbon cathode harvest a high energy/power density of 115.5 Wh·kg^-1/5,742 W·kg^-1,holding promise for next-generationen ergy storages. | Chen Lu Zhenzhu Li Zhou Xia Haina Ci Jingsheng Cai Yingze Song Lianghao Yu Wanjian Yin Shixue Dou Jingyu Sun Zhongfan Liu | 2019 | Nano Research2019，12，12： | 7 |
| 13 | A random medium model for simulation of concrete failure显示文摘A random medium model is developed to describe damage and failure of concrete.In the first place,to simulate the evolving cracks in a mesoscale,the concrete is randomly discretized as irregular finite elements.Moreover,the cohesive elements are inserted into the adjacency of finite elements as the possible cracking paths.The spatial variation of the material properties is considered using a 2-D random field,and the stochastic harmonic function method is adopted to simulate the sample of the fracture energy random field in the analysis.Then,the simulations of concrete specimens are given to describe the different failure modes of concrete under tension.Finally,based on the simulating results,the probability density distributions of the stress-strain curves are solved by the probability density evolution methods.Thus,the accuracy and efficiency of the proposed model are verified in both the sample level and collection level. | LIANG ShiXue REN XiaoDan LI Jie | 2013 | Science China(Technological Sciences)2013，56，5： | 6 |

Advanced functional nanomaterials and relevant nanotechnologies are playing a crucial role and showing promise in resolving some energy issues. In this view, we focus on recent advances of functional nanomaterials in clean energy applications, including solar energy conversion, water splitting, photodegradation, electrochemical energy conversion and storage, and thermoelectric conversion, which have attracted considerable interests in the regime of clean energy. | Jinyan Xiong Chao Han Zhen Li Shixue Dou | 2015 | Science Bulletin2015，60，24： | 6 |

| 16 | New observations of the lobopod-like worm Facivermis from the Early Cambrian Chengjiang Lagerstatte显示文摘Facivermis yunnanicus (Hou & Chen, 1989), from the Early Cambrian Chengjiang Lager- st?tte, a worm-like fossil with 5 pairs of tentacles and a perceived shrunken end, has been regarded as related to polychaetes, later it has been variously interpreted as lobopods, Pentastoma and lopho- phorates. Newly discovered complete specimens by the ELI field team show that the taxon has, in addition to the 5 pairs of appendages, a pear-shaped trunk end bearing two or three circles of hooks. Accordingly, based on these important morphological characters, reconsideration of its affinities is provided and the taxonomy is remedied herein. Because the five pairs of appendages of Facivermis yunnanicus resemble the appendages of the fore-trunk of lobopod Mi- raluolishania (Liu & Shu, 2004), it seems that they are homologous structures. Therefore, the affinities of Facivermis are regarded here as being close to the lobopods, in addition, the lobe-like appendages of Facivermis are very crucial to exploring the origin of the appendages of lobopods and arthropods. | LIU Jianni HAN Jian SIMONETTAA.

| 17 | A New Arthropod,Guangweicaris Luo,Fu et Hu gen. nov. from the Early Cambrian Guanshan Fauna,Kunming,China显示文摘The Guanshan Fauna is a soft-bodied fauna dominated by arthropods (including trilobites, trilobitoides, Tuzoia, Isoxys, and bradorids) in association with priapulids, brachiopods, anomalocaridids, vetulicoliids, sponges, chancellorids, and echinoderms. This paper reports and describes a new arthropod from the yellowish green mudstone at the lower part of the Wulongqing Formation, Canglangpuan Stage, Lower Cambrian in Kunming, Yunnan, China. The stratigraphic and geographic distribution, classification, fossil preservation, life style of this new arthropod and comparisons with other fossil arthropods are also discussed in details. The discovery and research of the non-mineralized arthropod, Guangweicaris Luo, Fu et Hu gen. nov. from the Guanshan Fauna adds new members to the taxonomic list and provides new information to the evolution of early arthropods. Furthermore, this study would shed new light into the “Cambrian Explosion” and the evolution of early life. | LUO Huilin FU Xiaoping HU Shixue LI Yong HOU Shuguang YOU Ting PANG Jiyuan LIU Qi | 2007 | Acta Geologica Sinica(English Edition)2007，81，1： | 5 |
| 18 | Palaeoecological Analysis of Trace Fossil Sinusichnus sinuosus from the Middle Triassic Guanling Formationin Southwestern China显示文摘The Luoping Biota discovered from the early Middle Triassic(Anisian) Guanling Formation of southwestern China represents a fully recovered shallow marine ecosystem, marking the end point of Early Triassic biotic recovery following the end-Permian mass extinction. Contemporaneously preserved are prolific trace fossils, which offer good opportunities to understand the palaeoecology of marine invertebrates from a fully recovered shallow marine ecosystem. Here we present a newly discovered sinuous branching burrow from the fossil-bearing unit in Member II of the Guanling Formation. Several features, including the horizontal regular sinuous nature, the branching pattern, typical H-junction, and the small wavelength/amplitude ratio of these sinuous structures within the burrow systems justify assignment of these traces as Sinusichnus sinuosus, a trace possibly produced by decapod crustaceans. Close association of S. sinuosus with Rhizocorallium commune suggests a deposit-feeding strategy of these trace makers. The newly reported Anisian material from the Guanling Formation in Luoping represents first report of Sinusichnus from South China. The global record of Sinusichnus occurrence suggests that these burrows might have an older history than Early Middle Triassic. | Mao Luo Yi-Ming Gong G. R.

| 19 | Synergistic impact of cocatalysts and hole scavenger for promoted photocatalytic H2 evolution in mesoporous TiO2–NiSx hybrid显示文摘Photocatalytic solar energy conversion to hydrogen is sustainable and attractive for addressing the global energy and environmental issue. Herein, a novel photocatalytic system (NiS/Ni3S4 cocatalysts modified mesoporous TiO2) with superior photocatalytic hydrogen evolution capability through the synergistic impact of NiS/Ni3S4 (NiSx) cocatalyst and efficient hole scavenger has been demonstrated. The photocatalytic hydrogen evolution of TiO2-NiSx hybrids with the different content of NiSx and upon different organic hole scavengers was both investigated. The hybrid of TiO2 decorated with 3%(mole ratio of Ni^2+) NiSx cocatalyst in methanol solution showed the optimal photocatalytic hydrogen evolution rate of 981.59 μmol h^-1 g^-1 which was about 20 times higher than that of bare mesoporous TiO2. Our results suggested that the boosted hydrogen production performance is attributed to both the improved photoinduced electrons migration between NiS and Ni3S4 in cocatalyst and the high hole captured efficiency by hole scavengers of methanol. | Yi Wei Gang Cheng Jinyan Xiong Jiaxin Zhu Yixin Gan Mengmeng Zhang Zhen Li Shixue Dou | 2019 | Journal of Energy Chemistry2019，28，5： | 3 |
| 20 | Confining TiO_2 Nanotubes in PECVD-Enabled Graphene Capsules Toward Ultrafast K-Ion Storage: In Situ TEM/XRD Study and DFT Analysis显示文摘Titanium dioxide(TiO2) has gained burgeoning attention for potassium-ion storage because of its large theoretical capacity,wide availability,and environmental benignity.Nevertheless,the inherently poor conductivity gives rise to its sluggish reaction kinetics and inferior rate capability.Here,we report the direct graphene growth over TiO2 nanotubes by virtue of chemical vapor deposition.Such conformal graphene coatings effectively enhance the conductive environment and well accommodate the volume change of TiO2 upon potassiation/depotassiation.When paired with an activated carbon cathode,the graphene-armored TiO2 nanotubes allow the potassium-ion hybrid capacitor full cells to harvest an energy/power density of 81.2 Wh kg-1/3746.6 W kg-1.We further employ in situ transmis sion electron microscopy and ope rando X-ray diffraction to probe the potassium-ion storage behavior.This work offers a viable and versatile solution to the anode design and in situ probing of potassium storage technologies that is readily promising for practical applications. | Jingsheng Cai Ran Cai Zhongti Sun Xiangguo Wang Nan Wei Feng Xu Yuanlong Shao Peng Gao Shixue Dou Jingyu Sun | 2020 | Nano-Micro Letters2020，12，9： | 2 |
