| 1 | Features and Formation Mechanism of Faults and Potash-forming Effect in the Lop Nur Salt Lake,Xinjiang,China显示文摘The Lop Nur Salt Lake, located in the eastern part of the Tarim Basin, Xinjiang, China, has become a playa in the Quaternary. Rhombic in shape, the Lop Nur depression is mainly controlled by the NE-striking and nearly N-S-striking sets of faults. Since 1995, a superlarge brine potash deposit with potash resources of 2.50×108 t has been found in the Luobei subbasin in the northeastern part of the Lop Nur. We intensively studied the features and formation mechanism of faults inside the Lop Nur through satellite images, geomorphologic survey and continuous conductivity imaging and found seven subparallel graben faults formed under the action of nearly N 10o E principal compressional stress during deposition of the Lop Nur Salt Lake. These faults are up to >60 km long and 1–4 km wide and may extend downward for 1000 m or more. It is just under the action of these tensional faults that potash subbasins formed. The largest subbasin is the Luobei subbasin and the smaller ones are the Luoxi hollow, Erbei hollow and Tienan hollow. Investigation also indicates that the graben faults in the Lop Nur not only control the origin of the potash subbasins, but they themselves are also good brine reservoir structures, in which abundant potash-rich brines are stored. Therefore, The faults had played an important role in the potash formation of the Lop Nur. | LIU Chenglin WANG Mili JIAO Pengcheng LI Shude CHEN Yongzhi | 2006 | Acta Geologica Sinica(English Edition)2006，80，6： | 33 |
| 2 | The Impact of the Linked Factors of Provenance,Tectonics and Climate on Potash Formation:An Example from the Potash Deposits of Lop Nur Depression in Tarim Basin,Xinjiang,Western China显示文摘Potash deposits commonly accumulate in highly restricted settings at the final stage of brine evaporation. This does not mean that potash deposits are formed simply as a result of the evaporation concentration of seawater or lake water, but rather as a coupling result of particular provenance, tectonics and climate activities. In this paper, we focus on the formative mechanism of the potash deposits of Lop Nur depression in Tarim Basin to interpret the detailed coupling mechanism among provenance, tectonics and climate. In terms of the provenance of Lop Nur Lake, the water of the Tarim River which displays 'potassium-rich' characteristics play an important role. In addition, the Pliocene and Lower-Middle Pleistocene clastic beds surrounding Lop Nur Lake host a certain amount of soluble potassium and thus serves as 'source beds' for potash formation. During the late Pliocene, the Lop Nur region has declined and evolved into a great lake from the previous piedmont and diluvial fan area. Since the mid Pleistocene, the great-united Lop Nur Lake has been separated and has generated a chain system consisting of Taitema Lake, Big Ear Lake and Luobei Lake which has turned into the deepest sag in Lop Nur Lake. Dry climate in Lop Nur region has increased since the Pliocene, and became extreme at the late Pleistocene. The study implies that potash formation in Lop Nur Lake depends on the optimal combination of extreme components of provenance, tectonics and climate during a shorter-term period. The optimal patterns of three factors are generally characterized by the long-term accumulation and preliminary enrichment of potassium, the occurrence of the deepest sub-depression and the appearance of an extremely arid climate in Lop Nur region. These factors have been interacting synergistically since the forming of the saline lake and in the later stages strong 'vapor extraction' caused by extremely arid climate is needed to trigger large scale mineralization of potash deposits. | LIU Chenglin JIAO Pengcheng Lü Fenglin WANG Yongzhi SUN Xiaohong ZHANG Hua WANG Licheng YAO Fojun | 2015 | Acta Geologica Sinica(English Edition)2015，89，6： | 18 |
| 3 | Recursive modeling and online identification of lithium-ion batteries for electric vehicle applications显示文摘For safe and reliable operation of lithium-ion batteries in electric vehicles,the real-time monitoring of their internal states is important.The purpose of our study is to find an easily implementable,online identification method for lithium-ion batteries in electric vehicles.In this article,we propose an equivalent circuit model structure.Based on the model structure we derive the recursive mathematical description.The recursive extended least square algorithm is introduced to estimate the model parameters online.The accuracy and robustness are validated through experiments and simulations.Real-road driving cycle experiment shows that the proposed online identification method can achieve acceptable accuracy with the maximum error of less than 5.52%.In addition,it is proved that the proposed method can also be used to estimate the real-time SOH and SOC of the batteries. | LI Yong WANG LiFang LIAO ChengLin WANG LiYe XU DongPin | 2014 | Science China(Technological Sciences)2014，57，2： | 10 |

| 6 | Degree of Brine Evaporation and Origin of the Mengyejing Potash Deposit:Evidence from Fluid Inclusions in Halite显示文摘The Mengyejing potash deposit is located in the southern port of the Simao Basin, Yunnan Province, and is hosted in mid-Cretaceous strata. The chemical compositions of fluid inclusions in halite crystals, collected from the level-610 adit in the deposit, were analysed by laser ablation inductively coupled plasma mass spectrometry(LA-ICP-MS). The results show that the brine is of the Na-K-Mg-Ca-Cl type and has K concentrations that are distinctly higher than those of Mg and Ca, unlike normal brines associated with Cretaceous halite. The high K concentrations indicate that the degree of evaporation of the ancient Mengyejing saline lake was very high, reaching the sylvite deposition stage but rarely reaching the carnallite deposition stage. The trajectory of the H and O isotopic compositions of the brines in the halite-hosted fluid inclusions corresponds to intense evaporation, indicating that the net evaporation exceeded the net inflow of brines. These brine compositions in halite-hosted fluid inclusions were likely formed by the dissolution of previously deposited K-bearing minerals by fresh continental and/or seawater, forming a type of modified seawater, with deep hydrothermal fluids potentially supplying additional potassium. The basin likely experienced multiple seawater incursion, dissolution and redeposition events in a high-temperature environment with high evaporation rates. | SHEN Lijian LIU Chenglin WANG Licheng HU Yufei HU Mingyue FENG Yuexing | 2017 | Acta Geologica Sinica(English Edition)2017，91，1： | 9 |
| 7 | Recanalisation therapy in patients with acute ischaemic stroke caused by large artery occlusion:choice of therapeutic strategy according to underlying aetiological mechanism?显示文摘Various mechanisms underlie causative large artery occlusion(LAO)in patients with acute ischaemic stroke.Cardioembolic and atherosclerotic occlusions are the two most common types.The pathophysiological changes and responses to mechanical thrombectomy(MT)and antithrombotic treatments including thrombolysis,antiplatelet and anticoagulation therapy may vary among patients with different aetiological mechanisms of occlusion.Atherosclerotic occlusion is inclined to have relatively abundant collaterals and larger area of penumbra,hence a relatively wider time window for reperfusion therapy,while poor response to medical thrombolysis and MT.Severe residual stenosis and reocclusion occurred frequently after MT in atherosclerotic LAO.Angioplasty and stenting as rescue or the first-line therapy and more intensified antiplatelet therapy beyond related recommendations in the current guidelines are sometimes used in managing acute causative LAO because of poor recanalisation after recommended standard thrombolysis or MT therapy,which are usually based on individual experience.Standard protocol to establish emergent aetiological diagnosis of causative LAO and individualised aetiology-specific treatment strategy is needed. | Chenglin Tian Xiangyu Cao Jun Wang | 2017 | Stroke & Vascular Neurology2017，2，4： | 9 |
| 8 | Advanced hydrogels for the repair of cartilage defects and regeneration显示文摘Cartilage defects are one of the most common symptoms of osteoarthritis(OA),a degenerative disease that affects millions of people world-wide and places a significant socio-economic burden on society.Hydrogels,which are a class of biomaterials that are elastic,and display smooth surfaces while exhibiting high water content,are promising candidates for cartilage regeneration.In recent years,various kinds of hydrogels have been developed and applied for the repair of cartilage defects in vitro or in vivo,some of which are hopeful to enter clinical trials.In this review,recent research findings and developments of hydrogels for cartilage defects repair are summarized.We discuss the principle of cartilage regeneration,and outline the requirements that have to be fulfilled for the deployment of hydrogels for medical applications.We also highlight the development of advanced hydrogels with tailored properties for different kinds of cartilage defects to meet the requirements of cartilage tissue engineering and precision medicine. | Wei Wei Yuanzhu Ma Xudong Yao Wenyan Zhou Xiaozhao Wang Chenglin Li Junxin Lin Qiulin He Sebastian Leptihn Hongwei Ouyang | 2021 | Bioactive Materials2021，6，4： | 8 |
| 9 | Wnt/β-catenin signaling in cancers and targeted therapies显示文摘Wnt/β-catenin signaling has been broadly implicated in human cancers and experimental cancer models of animals.Aberrant activation of Wnt/β-catenin signaling is tightly linked with the increment of prevalence,advancement of malignant progression,development of poor prognostics,and even ascendence of the cancer-associated mortality.Early experimental investigations have proposed the theoretical potential that efficient repression of this signaling might provide promising therapeutic choices in managing various types of cancers.Up to date,many therapies targeting Wnt/β-catenin signaling in cancers have been developed,which is assumed to endow clinicians with new opportunities of developing more satisfactory and precise remedies for cancer patients with aberrant Wnt/β-catenin signaling. | Fanyuan Yu Changhao Yu Feifei Li Yanqin Zuo Yitian Wang Lin Yao Chenzhou Wu Chenglin Wang Ling Ye | 2021 | Signal Transduction and Targeted Therapy2021，6，9： | 8 |
| 10 | Heavy metal contamination of urban topsoil in a petrochemical industrial city in Xinjiang, China显示文摘Heavy metal pollution is a widespread phenomenon in many countries of the world.In this study,we conducted a field investigation to assess the status of heavy metal pollution in urban soils of Dushanzi,a district of Karamay city in Xinjiang,China.A total of 56 soil samples in the topsoil layer of 0–15 cm were collected within the urban area and seven elements(Cu,Zn,Cd,Pb,Cr,As and Ni) were analyzed.The mean concentrations of these metals were all higher than their corresponding background values of soils in Xinjiang.We used the pollution index and ecological risk index to assess the degree of heavy metal pollution and the potential ecological risk of urban soils.The pollution index values of Cu,Zn,Cd,Pb,Cr,As and Ni were 1.81,1.35,4.64,1.27,1.80,1.39 and 1.22,respectively;and the potential ecological risk index values for them were 12.03,1.79,185.05,8.39,4.78,18.44 and 1.79,respectively.These results indicated that urban soils in Dushanzi were polluted by heavy metals to some extent and demonstrated a high ecological risk,as influenced by industrial activities.Cd was the key element for the metal pollution of urban soils in the study area.Correlation analyses,principal component analysis coupled with the spatial distribution maps of element concentrations further revealed that heavy metal pollution of urban soils can be mainly attributed to petrochemical industry,coal chemical industry,traffic and commercial activities. | WANG Wei LAI Yingshuai MA Yuanyuan LIU Zilong WANG Shufen HONG Chenglin | 2016 | Journal of Arid Land2016，8，6： | 7 |
| 11 | Quaternary Climate and Environment in the Lop Nur,Xinjiang显示文摘Since the middle Early Pleistocene (1.20 Ma B.P.), the desert steppe climate and environment have predominated in the Lop Nur area, Xinjiang, characterized by warm humid epochs interrupted by dry cold intervals. The grain-size and magnetic susceptibility curves record 30 climatic oscillations, each with a ca. 40 ka cycle, in the area since 1.2 Ma B.P., which reflects the controlling effects exerted by the astronomic factor on the environment. The Quaternary sedimentary environment in the Lop Nur gradually changed from a fresh lake through a brackish lake to a saline lake, showing a spiral evolution, and finally it evolved into a playa. | WANG Mill PU Qingyu LIU Chenglin CHEN Yongzhi | 2000 | Acta Geologica Sinica(English Edition)2000，74，2： | 7 |
| 12 | A Cretaceous Desert-Playa Sedimentary System Controlled the Potash Formation in the Simao Basin显示文摘Objective The Simao Basin in Yunnan Province has developed Cretaceous evaporite-bearing clastic deposits,including the Mangang and Mengyejing Formations which were originally interpreted as fluvial and lacustrine deposits.The Mangang Fm.composed of well-rounded quartz sandstones,were commonly considered as the bottom part of the Mengyejing salt series.During last decades,drilling projects targeting to prospect solid potash deposits in the Mengyejing salt series consequently ceased when encountering these sandstones.The poor understanding of sedimentary environments leads to no breakthrough of prospecting solid potash deposits in the Simao Basin. | WU Chihua LIU Chenglin SHEN Lijian WANG Jiuyi ZHANG Hua | 2017 | Acta Geologica Sinica(English Edition)2017，91，3： | 6 |

| 14 | Scalable fabrication of printed Zn//MnO2 planar micro-batteries with high volumetric energy density and exceptional safety显示文摘The rapid development of printed and microscale electronics imminently requires compatible micro-batteries(MBs)with high performance,applicable scalability,and exceptional safety,but faces great challenges from the ever-reported stacked geometry.Herein the first printed planar prototype of aqueous-based,high-safety Zn//MnO2 MBs,with outstanding performance,aesthetic diversity,flexibility and modularization,is demonstrated,based on interdigital patterns of Zn ink as anode and MnO2 ink as cathode,with high-conducting graphene ink as a metal-free current collector,fabricated by an industrially scalable screen-printing technique.The planar separator-free Zn//MnO2 MBs,tested in neutral aqueous electrolyte,deliver a high volumetric capacity of 19.3 mAh/cm^3(corresponding to 393 mAh/g)at 7.5 mA/cm^3,and notable volumetric energy density of 17.3 mWh/cm^3,outperforming lithium thin-film batteries(≤10 mWh/cm^3).Furthermore,our Zn//MnO2 MBs present long-term cyclability having a high capacity retention of 83.9%after 1300 cycles at 5 C,which is superior to stacked Zn//MnO2 batteries previously reported.Also,Zn//MnO2 planar MBs exhibit exceptional flexibility without observable capacity decay under serious deformation,and remarkably serial and parallel integration of constructing bipolar cells with high voltage and capacity output.Therefore,low-cost,environmentally benign Zn//MnO2 MBs with in-plane geometry possess huge potential as high-energy,safe,scalable and flexible microscale power sources for direction integration with printed electronics. | Xiao Wang Shuanghao Zheng Feng Zhou Jieqiong Qin Xiaoyu Shi Sen Wang Chenglin Sun Xinhe Bao Zhong-Shuai Wu | 2020 | National Science Review2020，7，1： | 5 |
| 15 | Neuroprotective effects of total saponins from Rubus parvifolius L. on cerebral ischemia/reperfusion injury in rats显示文摘This study examines the neuroprotective effects and mechanisms of action of total saponins from Rubus parvifolius L. (TSRP) on focal cerebral ischemia and reperfusion injury in rats. Focal cerebral ischemia and reperfusion injury was performed in rats using the suture method. The results indicate that intragastric injection of TSRP, at 5, 10 and 20 mg/kg, could decrease neurological impairment, reduce cerebral infarct volume, diminish pathological changes, and significantly inhibit the apoptosis of neurons surrounding the ischemic area. In addition, TSRP upregulated the expression of the anti-apoptotic factor Bcl-2, at the protein and mRNA levels, and it downregulated the expression of the pro-apoptotic factor Bax, at the protein and mRNA levels. These findings indicate that TSRP protects against cerebral ischemia/reperfusion injury, and that it may do so by regulating the expression of Bcl-2 and Bax. | Jisheng Wang Fang Zhang Li Tang Liqiong Sun Xiaolin Song] Lisha Cao Zongyin Qiu Chenglin Zhou | 2012 | Neural Regeneration Research2012，7，3： | 5 |
| 16 | Multiple Dolomitization and Fluid Flow Events in the Precambrian Dengying Formation of Sichuan Basin, Southwestern China显示文摘The Precambrian Dengying Formation is a set of large-scale, extensively dolomitized, carbonate reservoirs occurring within the Sichuan Basin. Petrographic and geochemical studies reveal dolomitization was a direct result of precipitation by chemically distinct fluids occurring at different times and at different intensities. Based on this evidence, dolomitization and multiple fluid flow events are analyzed, and three types of fluid evolution models are proposed. Results of analysis show that Precambrian Dengying Formation carbonates were deposited in a restricted peritidal environment(630–542 Ma). A high temperature and high Mg^(2+) concentration seawater was a direct result of dolomitization for the micrite matrix, and for fibrous aragonite in primary pores. Geochemical evidence shows low δ^(18)O values of micritic dolomite varying from-1.29‰ to-4.52‰ PDB, abundant light rare earth elements(REEs), and low dolomite order degrees. Microbes and meteoric water significantly altered dolomite original chemical signatures, resulting in algal micritic dolomite and the fine-grained, granular, dolosparite dolomite having very negative δ^(18)O values. Finely crystalline cement dolomite(536.3–280 Ma) and coarsely crystalline cement dolomite have a higher crystallization degree and higher order degree. The diagenetic sequence and fluid inclusion evidence imply a linear correlation between their burial depth and homogenization temperatures, which closely resemble the temperature of generated hydrocarbon. Compared with finely crystalline dolomite, precipitation of coarsely crystalline dolomite was more affected by restricted basinal fluids. In addition, there is a trend toward a more negative δ^(18)O value, higher salinity, higher Fe and Mn concentrations, REE-rich. Two periods of hydrothermal fluids are identified, as the exceptionally high temperatures as opposed to the temperatures of burial history, in addition to the presence of high salinity fluid inclusions. The early hydrothermal fluid flow event was characterized by hot magnesium-and silicon-rich fluids, as demonstrated by the recrystallized matrix dolomite that is intimately associated with flint, opal, and microcrystalline quartz in intergranular or intercrystalline pores. This event was likely the result of a seafloor hydrothermal chimney eruption during Episode I of the Tongwan Movement(536.3±5.5 Ma). In contrast, later hydrothermal fluids, which caused precipitation of saddle dolomite, were characterized by high salinity(15–16.05 wt% NaCl equivalent) and homogenization temperatures(250 to 265°C), δ^(18)O values that were more enriched, and REE signatures. Geochemical data and the paragenetic sequence indicate that this hydrothermal fluid was related to extensive Permian large igneous province activity(360–280 Ma). This study demonstrates the presence of complicated dolomitization processes occurring during various paleoclimates, tectonic cycles, and basinal fluids flow; results are a useful reference for these dolomitized Precambrian carbonates reservoirs. | PENG Bo LI Zongxing LI Guorong LIU Chenglin ZHU Shifa ZHANG Wang ZUO Yinhui GUO Yingchun WEI Xiaojie | 2018 | Acta Geologica Sinica(English Edition)2018，92，1： | 5 |
| 17 | Lactic Acid Assisted Solvothermal Synthesis of BiOClxI1-x Solid Solutions as Excellent Visible Light Photocatalysts显示文摘A series of BiOClxI1-x(x=0,0.1,0.3,0.5,0.7,0.9,1.0)photocatalysts was firstly prepared by means of a facile solvothermal route with the help of lactic acid.The measured results show that the morphologies of the as-prepared samples are similar sheets with different thickness and diameters.Thinner nanosheets assembled flower-like BiOCI0.5I0.5 solid solution exhibited the highest photocatalytic activity and stability among the prepared samples for the degradation of methylene blue(MB)and methyl orange(MO)under the illumination of visible light.The excellent photocatalytic properties of BiOCI0.5I0.5 could be attributed to the high specific surface area,the suita-ble band gap energy and the lower recombination rate of the electrons and holes.In addition,catalyst BiOCI0.5I0.5 was further used to degradate a more complicated mixed dye(MCH-RhB+MB)system under visible light,displaying an excellent photocatalytic activity.Finally,the photocatalytic mechanism of catalyst BiOCI0.5I0.5 to degradate colorful dyes was proposed.The trapping experiments of active species indicated that the holes are the main active species for the degradation of the mixed dyes. | DUAN Chenglin SONG Jinling WANG Baoying LI Lun WANG Ruifen ZHANG Bangwen | 2019 | Chemical Research in Chinese Universities2019，35，2： | 4 |
| 18 | Light-triggered interfacial charge transfer and enhanced photodetection in CdSe/ZnS quantum dots/MoS_(2)mixed-dimensional phototransistors显示文摘Mix-dimensional van der Waals heterostructures(vdWHs)have inspired worldwide interests and efforts in the field of ad-vanced electronics and optoelectronics.The fundamental understanding of interfacial charge transfer is of vital import-ance for guiding the design of functional optoelectronic applications.In this work,type-Ⅱ0D-2D CdSe/ZnS quantum dots/MoS_(2)vdWHs are designed to study the light-triggered interfacial charge behaviors and enhanced optoelectronic performances.From spectral measurements in both steady and transient states,the phenomena of suppressed photolu-minescence(PL)emissions,shifted Raman signals and changed PL lifetimes provide strong evidences of efficient charge transfer at the 0D-2D interface.A series of spectral evolutions of heterostructures with various QDs overlapping concentrations at different laser powers are analyzed in details,which clarifies the dynamic competition between exciton and trion during an efficient doping of 3.9×10^(13)cm^(−2).The enhanced photoresponses(1.57×10^(4)A·W^(-1))and detectivities(2.86×10^(11)Jones)in 0D/2D phototransistors further demonstrate that the light-induced charge transfer is still a feasible way to optimize the performance of optoelectronic devices.These results are expected to inspire the basic understand-ing of interfacial physics at 0D/2D interfaces,and shed the light on promoting the development of mixed-dimensional op-toelectronic devices in the near future. | Ziwei Li Wen Yang Ming Huang Xin Yang Chenguang Zhu Chenglin He Lihui Li Yajuan Wang Yunfei Xie Zhuoran Luo Delang Liang Jianhua Huang Xiaoli Zhu Xiujuan Zhuang Dong Li Anlian Pan | 2021 | Opto-Electronic Advances2021，4，9： | 4 |
| 19 | Revealing the influence of high magnetic field on the solute distribution during directional solidification of Al-Cu alloy显示文摘The effect of the high magnetic field(MF)on the distribution of solute concentration during directional solidification of Al-Cu alloy under low growth speed was experimentally investigated.The amount of nonequilibrium eutectic is quantified via X-ray computed tomography(XCT)and demonstrated to reduce with the application of MF.Further,experimental results reveal that the MF alleviates the microsegregation and increases the average Cu concentration in solid solution,leading to the increases of the effective partition coefficient ke.It was also found that Cu concentration in solid solution increases continuously with the increasing intensity of MF,following the strengthening of micro-hardness.The change of ke under the MF is demonstrated to attribute to the thermoelectric magnetic convection(TEMC)in the mushy zone and the thermoelectric magnetic force(TEMF)acting on the solid.The TEMC is supposed to cause secondary convection owing to the inequality in flow velocities of circulation in different positions of dendrite stem.And the vacancies created by the proliferation and movement of dislocations induced by TEMF in the matrix is supposed to be able to capture solute atoms and thus enhance the solute concentration in the solid solution. | Pengchuan Wang Sansan Shuai Chenglin Huang Xin Liu Yanan Fu Jiang Wang Zhongming Ren | 2021 | Journal of Materials Science & Technology2021，，29： | 3 |
