1Paleostructural geomorphology of the Paleozoic central uplift belt and its constraint on the development of depositional facies in the Tarim Basin显示文摘Inclined eastward and consisting of the Hetianhe, Hetianhedong, Tazhong paleouplifts and Bachu paleoslope, the central paleouplift belt in the Tarim Basin was a large composite paleouplift and paleoslope belt with complicated palaeogeomorphic features during the Middle to early Late Ordovician. A number of paleostructural geomorphic elements have been identified in the paleouplift belt and surrounding areas, such as the high uplift belts, the faulted uplift platforms, the marginal slopes and slope break zones flanking the paleouplift belt, the surrounding shelf slopes or low relief ramps, the shelf slope break zones and deep basin plains. They exerted great influence on the development of paleogeography of the basin. The marginal slopes and slope break zones flanking the uplift belt constrained the formation and deposition of the high-energy facies including reefal and shoal deposits during the Late Ordovician, which comprise the major reservoirs of the Lower Paleozoic in the basin. Toward the end of the Ordovician, the Tazhong paleouplift hinged westward and became a westward-dipped nose as the southeastern margin of the basin was strongly compressed and uplifted. The tectono-paleogeomorphic framework of the central northern basin during the Early Silurian and the Late Devonian to Early Carboniferous changed remarkably in topography from the initial low in east and high in west to high in northeast and low in southwest. The major paleogeomorphic elements developed in these periods included the strong eroded uplift high, the uplift marginal slope, the gentle ramp of the depression margin and the depression belt. The sandstones of the lowstand and the early transgressive systems tracts were deposited along the uplift marginal slopes and the gentle ramps of the depressions comprise the prolific reservoirs in the basin. The study indicates that the distribution patterns of the unconformities within the basin are closely related to the paleogeomorphic features and evolution of the paleouplift belt. From the high uplift belt to the depression, we found the composed unconformity belts at the high uplift, the truncated and onlap triangular unconformity belts along the uplift marginal slopes, the minor angular unconformity or discontinuity belts along the transitional zones from the uplift marginal slopes to depression and the conformity belt in the central depression. The truncated and the onlap triangular unconformity belts are the favorable zones for the formation of stratigraphic trap reservoirs.LIN ChangSong YANG HaiJun LIU JingYan PENG Li CAI ZhenZhong YANG XiaoFa YANG YongHeng 2009Science China Earth Sciences2009,52,6:52

3Depositional architecture and developing settings of large-scale incised valley and sub-marine gravity flow systems in the Yinggehai and Qiong-dongnan basins,South China Sea显示文摘In the Ying-Qiong basins in the South China Sea developed a set of giant inner shelf slope and submarine gravity flow deposits in the Ying-Huang formations since the Late Miocene. These deposits can be classified into 9 sequences in which slope slump-debris flow, slope fan and particularly, the large-scale axial basin-floor incised valley fills have been recognized. They were distributed in a distinctive pattern attributed to tectonic control. The development ofshelf slopes and abyssal plains in the basins was related to the last episode of rapid subsidence and a large amount of sediment inputs. Large-scale basin-floor incised valleys, formed during the late Miocene and Pliocene, indicate several major sea level falls that occurred in the South China Sea.LIN Changsong LIU Jingyan CAI Shixiang ZHANG Yanmei LU Ming LI Jie 2001Chinese Science Bulletin2001,46,8:18
4Palaeogeomorphology and its control on the development of sequence stratigraphy and depositional systems of the Early Silurian in the Tarim Basin显示文摘The Silurian in the Tarim Basin was deposited on the basement deformed by the Caledonian tectonic movements at the end of the Late Ordovician. The development and distribution of sedimentary sequences of the Early Silurian have been clearly controlled by the palaeogeomorphology of the Late Ordovician. Based on unconformity characteristics and distribution of erosion, several zones can be differentiated including a high uplifted erosion zone, a transitional slope zone and a depression zone. The central and west Tabei Uplift zones show high angular unconformity and intense erosion. The Tarim Basin in the late Ordovician shows characteristics of higher in the west, lower in the east while higher in the south, lower in the north. The Early Silurian mainly developed transgressive and highstand systems tracts on the whole, while the lowstand systems tract only developed partly below the slope break. The palaeogeomorphology controlled the clastic source supply and deposit distribution. Braided delta system and tidal flat–estuary system were deposited. The duration of uplifting of the Tazhong paleouplift was longer than that of the Tabei paleo-uplift, and deposition was later. This led to the lower and middle members of the Kepingtage Formation missing in that area. As a large-scale transgression occurred during the deposition period of the upper member of the Kepingtage Formation, sediment from the west of the basin was transported and deposited by tides and waves, forming tidal–marine debris systems above the uplift. Proximal alluvial fan and fan delta coarse clastic deposits developed in proximal uplift zone in the east and southeast of the basin, and braided delta put forward to the transitional zone between the edge of uplift and the sea. Large-scale tidal channel, sub-distributary channel and mouth bar of the delta front can form favorable reservoirs, and they are primary targets for oil and gas exploration. This research on sequence–depositional systems development and distribution controlled by palaeogeomorphology is significant in guiding the prediction of reservoir sandstones.Liu Jingyan Lin Changsong Cai Zhenzhong Zhu Yongfeng Yang Yongheng Peng Li Si Baoling Huang Zhen Li Huanpu Xu Yingcai Su Zhenzhen 2010Petroleum Science2010,7,3:13
5Comprehensive analysis of NAC transcription factors in diploid Gossypium: sequence conservation and expression analysis uncover their roles during fiber development显示文摘Determining how function evolves following gene duplication is necessary for understanding gene expansion.Transcription factors(TFs)are a class of proteins that regulate gene expression by binding to specific cis-acting elements in the promoters of target genes,subsequently activating or repressing their transcription.In the present study,we systematically examined the functional diversification of the NAC transcription factor(NAC-TFs)family by analyzing their chromosomal location,structure,phylogeny,and expression pattern in Gossypium raimondii(Gr)and G.arboreum(Ga).The 145 and 141 NAC genes identified in the Gr and Ga genomes,respectively,were annotated and divided into 18 subfamilies,which showed distinct divergence in gene structure and expression patterns during fiber development.In addition,when the functional parameters were examined,clear divergence was observed within tandem clusters,which suggested that subfunctionalization had occurred among duplicate genes.The expression patterns of homologous gene pairs also changed,suggestive of the diversification of gene function during the evolution of diploid cotton.These findings provide insights into the mechanisms underlying the functional differentiation of duplicated NAC-TFs genes in two diploid cotton species.Haihong Shang Zhongna Wang Changsong Zou Zhen Zhang Weijie Li Junwen Li Yuzhen Shi Wankui Gong Tingting Chen Aiying Liu Juwu Gong Qun Ge Youlu Yuan 2016Science China(Life Sciences)2016,59,2:12
6A closed-loop process for recycling LiNi_xCo_yMn_((1-x-y))O_2 from mixed cathode materials of lithium-ion batteries显示文摘With the rapid development of consumer electronics and electric vehicles(EV), a large number of spent lithium-ion batteries(LIBs) have been generated worldwide. Thus, effective recycling technologies to recapture a significant amount of valuable metals contained in spent LIBs are highly desirable to prevent the environmental pollution and resource depletion. In this work, a novel recycling technology to regenerate a LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2 cathode material from spent LIBs with different cathode chemistries has been developed. By dismantling, crushing,leaching and impurity removing, the LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2(selected as an example of LiNi_xCo_yMn_(1-x-y)O_2) powder can be directly prepared from the purified leaching solution via co-precipitation followed by solid-state synthesis. For comparison purposes, a fresh-synthesized sample with the same composition has also been prepared using the commercial raw materials via the same method. X-ray diffraction(XRD), scanning electron microscopy(SEM) and electrochemical measurements have been carried out to characterize these samples. The electrochemical test result suggests that the re-synthesized sample delivers cycle performance and low rate capability which are comparable to those of the freshsynthesized sample. This novel recycling technique can be of great value to the regeneration of a pure and marketable LiNi_xCo_yMn_(1-x-y)O_2 cathode material with low secondary pollution.Rujuan Zheng Wenhui Wang Yunkun Dai Quanxin Ma Yuanlong Liu Deying Mu Ruhong Li Jie Rena Changsong Dai 2017Green Energy & Environment2017,2,1:11
7A New Process for Preparing Fine-ceramic-containing Composite Coatings──Flame Spray Synthesis显示文摘Flame spray synthesis (FSS), a combination of the flame spray technology and Self-propagation High-temperature Synthesis (SHS) was developed for preparing fine-ceramic-containing composite coatings. It can simplify the preparations of powder to synthesize and deposit the desired materials in one step. The preliminary results obtained from TiC-Fe cermet coatings by FSS process are reported. The peculiar microstructure of the composite coatings, which contains very fine (<1m) and round TiC and alternate TiC-rich (Hv=11€*13GPa) and TiC-poor layers (Hv=3.0 -6.0GPa), is expected to play an important role in their tribological properties.Changsong Liu, Jihua Huang, Sheng Yin (Material Science and Engineering School, University of Science and Technology Beijing, Beijing 100083, China) 2000International Journal of Minerals,Metallurgy and Materials2000,14,3:9
8Depositional architecture of the late Ordovician drowned carbonate platform margin and its responses to sea-level fluctuation in the northern slope of the Tazhong region, Tarim Basin显示文摘The Tazhong Uplift of the late Ordovician is a drowned rimmed carbonate platform. The carbonate rock of the late Ordovician Lianglitage Formation in the northern slope of the Tazhong region is one of the significant petroliferous intervals. Based on petrofacies, depositional cycles, natural gammaray spectrometry and carbon/oxygen isotope data from the Lianglitage Formation, one 2nd-order, three 3rd-order and several 4th-order sequences have been recognized, and the late Ordovician relative sealevel fluctuation curve has been established. The sequences O 3 l-1 and O 3 l-2 on the platform are composed of highstand and transgressive systems tracts, but lack the lowstand systems tract. The sequence O 3 l-3 is a drowning sequence. The sequence O 3 l-1 overlapped the eroded slope and pinched out to the northwest and landward. The highstand systems tract in the sequence O 3 l-2 consists of low-angle sigmoid and high-angle shingled progradation configuration. Major sedimentary facies of the Lianglitage Formation include reef and shoal in the platform margin and lagoon, which can be subdivided into coral-sponge-stromatoporoid reef complex, sand shoal, lime mud mound, and intershoal sea. Reefs, sand shoals and their complex are potential reservoir facies. The reefs and sand shoals in the sequence O 3 l-1 developed in the upper of its highstand systems tract. In the sequence O 3 l-2, the highstand systems tract with an internal prograding configuration is a response to the lateral shifting of the complex of reef and sand shoal. The transgressive systems tract, in particular the sand shoals, developed widely on the slope of the platform margin and interior. The reefs in the sequence O 3 l-3 migrated towards high positions and formed retrograding reefs in the western platform and low relief in the platform interior. Basinward lateral migration of the reefs and pure carbonate rock both characterize highstand systems tract and show that the rise of the relative sea-level was very slow. Shingled prograding stacking pattern of the 4th-order sequences and reefs grow horizontally, which represents the late stage of highstand systems tract and implies relative sealevel stillstand. Reefs migrating towards high land and impure carbonate rock both indicate transgressive systems tract and suggest that the relative sea-level rose fast. Erosional truncation and epidiagenetic karstification represent a falling relative sea-level. The relative sea-level fluctuation and antecedent palaeotopography control the development and distribution of reef complexes and unconformity karst zones. Currently, the composite zone of epidiagenetic karstic intervals and high-energy complexes of reefs and sand shoals with prograding configuration is an important oil and gas reservoir in the northern slope of the Tazhong carbonate platform.Yang Xiaofa Lin Changsong Yang Haijun Han Jianfa Liu Jingyan Zhang Yanmei Peng Li Jing Bing Tong Jianyu Wang Haiping Li Huanpu 2010Petroleum Science2010,7,3:8

10The thermal stability of dispersion-strengthened tungsten as plasma-facing materials:a short review显示文摘One key challenge for the development of fusion energy is plasma-facing materials.Tungsten-based materials are promising candidates for plasma-facing components(PFCs)in the magnetic confinement nuclear fusion reactors because of their high melt temperature,high-thermal conductivity,high-thermal load resistance,low tritium retention,and low sputtering yield.In fusion reactors,PFCs are exposed to high-thermal flux,because there are some transient events such as plasma disruptions,edge-localized modes,and vertical displacement events(VDEs).Especially,in VDEs,a heat flux of 10-100 MW m−2 with duration of milliseconds-to-several seconds can induce recrystallization and then change the microstructure of tungsten-based plasma-facing materials,leading to instability of microstructures.Then,a significant degradation of material properties is caused such as a reduction of mechanical strength and fracture toughness,a rise in the ductile-to-brittle-transition tempera-ture well,and decrease of irradiation/high-thermal load resistance.Therefore,many efforts were devoted to improve the thermal stability of tungsten-based materials as high as possible,such as oxide dispersion strengthening,carbide dispersion strengthening,and K bubbles dispersion strengthening.Here,the thermal stabilities of various dispersion-strengthened tungsten materials are reviewed by evaluating their recrystallization temperature and the corresponding hardness evolutions.In addition,the possible development trends are proposed.Tao Zhang Zhuoming Xie Junfeng Yang Ting Hao Changsong Liu 2019Tungsten2019,1,3:4
11Centralized control of parallel connected power conditioning system in electric vehicle charge-discharge and storage integration station显示文摘This study presents a centralized control scheme that coordinates parallel operations of power conditioning system(PCS)for the grid interactions of electric vehicles(EVs)in EV charge-discharge and storage integration station.Key issues for the control and operation of PCS under various operation modes are discussed,including vehicle to grid(V2G)mode,stand-alone mode and seamless transfer mode.The intelligent multi-mode charge-discharge method is utilized for the V2G mode,and the parallel control method based on communication network is adopted for the standalone mode.In addition,a novel seamless transfer strategy is proposed,which is able to implement PCS transition between V2G mode and stand-alone mode.The detailed process of the seamless transfer between the two modes is illustrated.Experimental results are presented to show the performance and feasibility of this strategy.Jiuqing CAI Changsong CHEN Peng LIU Shanxu DUAN 2015Journal of Modern Power Systems and Clean Energy2015,3,2:4
12Free-standing ZnO nanorod arrays modified with single-walled carbon nanotubes for betavoltaics and photovoltaics显示文摘A full-duplex radiant energy converter based on both betavoltaic and photovoltaic effects in an easyto-implement way is an attractive alternative for the autonomous wireless sensor microsystem.Here,we report a novel beta/photovoltaic cell based on free-standing Zn O nanorod arrays(ZNRAs)modified with metallic single-walled carbon nanotubes(m-SWCNTs),using radioisotope63 Ni as beta-emitting source.The ZNRAs were grown on Al-doped Zn O(AZO)conductive glass using hydrothermal method.The optimum length and diameter of Zn O nanorods were determined by Monte Carlo simulation for beta energy deposition in ZNRAs.The m-SWCNTs were anchored into the ZNRAs to form a three-dimensional(3-D)Schottky junction structure for effectively separating the beta/photo-excited electron-hole pairs.Experimentally,the betavoltaic and photovoltaic effects were confirmed through the I-V measurements of beta/photovoltaic cells under beta/UV/Vis irradiations,respectively.It is suggested that the m-SWCNTs play key role for the enhancement of beta/photovoltaic performance through the formation of extensive3-D Schottky junction,the conductive network for hole transport,and the surface plasmon resonance exciton absorption for visible light.Changsong Chen Jiang Chen Zhen Wang Jian Zhang Haisheng San Shichao Liu Chunyu Wu Werner Hofmann 2020Journal of Materials Science & Technology2020,54,19:3
13First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region.Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu 2021Science China(Physics,Mechanics & Astronomy)2021,64,8:3

16Spatial multi-scaled chimera states of cerebral cortex network and its inherent structure-dynamics relationship in human brain显示文摘Human cerebral cortex displays various dynamics patterns under different states,however the mechanism how such diverse patterns can be supported by the underlying brain network is still not well understood.Human brain has a unique network structure with different regions of interesting to perform cognitive tasks.Using coupled neural mass oscillators on human cortical network and paying attention to both global and local regions,we observe a new feature of chimera states with multiple spatial scales and a positive correlation between the synchronization preference of local region and the degree of symmetry of the connectivity of the region in the network.Further,we use the concept of effective symmetry in the network to build structural and dynamical hierarchical trees and find close matching between them.These results help to explain the multiple brain rhythms observed in experiments and suggest a generic principle for complex brain network as a structure substrate to support diverse functional patterns.Siyu Huo Changhai Tian Muhua Zheng Shuguang Guan Changsong Zhou Zonghua Liu 2021National Science Review2021,8,1:1

20A genome-wide identification of the BLH gene family reveals BLH1 involved in cotton fiber development显示文摘Background:Cotton is the world’s largest and most important source of renewable natural fiber.BEL1-like homeodomain(BLH)genes are ubiquitous in plants and have been reported to contribute to plant development.However,there is no comprehensive characterization of this gene family in cotton.In this study,32,16,and 18 BLH genes were identified from the G.hirsutum,G.arboreum,and G.raimondii genome,respectively.In addition,we also studied the phylogenetic relationships,chromosomal location,gene structure,and gene expression patterns of the BLH genes.Results:The results indicated that these BLH proteins were divided into seven distinct groups by phylogenetic analysis.Among them,25 members were assigned to 15 chromosomes.Furthermore,gene structure,chromosomal location,conserved motifs,and expression level of BLH genes were investigated in G.hirsutum.Expression profiles analysis showed that four genes(GhBLH1_3,GhBLH1_4,GhBLH1_5,and GhBLH1_6)from BLH1 subfamily were highly expressed during the fiber cell elongation period.The expression levels of these genes were significantly induced by gibberellic acid and brassinosteroid,but not auxin.Exogenous application of gibberellic acid significantly enhanced GhBLH1_3,GhBLH1_4,and GhBLH1_5 transcripts.Expression levels of GhBLH1_3 and GhBLH1_4 genes were significantly increased under brassinosteroid treatment.Conclusions:The BLH gene family plays a very important role in many biological processes during plant growth and development.This study deepens our understanding of the role of the GhBLH1 gene involved in fiber development and will help us in breeding better cotton varieties in the future.LIU Cuixia LI Zhifang DOU Lingling YUAN Yi ZOU Changsong SHANG Haihong CUI Langjun XIAO Guanghui 2020Journal of Cotton Research2020,3,3:1
