| 1 | Thermal convection thinning of the North China Craton: Numerical simulation显示文摘We used two-dimensional numerical simulations to investigate small-scale convection in the upper mantle-lithosphere system with depthand temperature-dependent viscosity. Our aim was to examine the mechanism of craton thinning by thermal convection. The model domain is 700 km deep and 700 km wide with a resolution of 71×71 nodes and 160000 markers. The velocity boundary conditions are free-slip along all the boundaries. A thermal insulation condition was applied at the two side walls, with constant temperatures for the top and bottom boundaries. We assumed an initial temperature of 273 K at the upper boundary and 1673 K at the lower boundary, and 1573 K at the bottom of the lithosphere (200 km depth) for the thick, cold, and stable North China Craton (NCC). We calculated the thermal evolution in the upper mantle when the temperature at its bottom is raised because of lower mantle convection or plumes. The temperature at the bottom of the upper mantle was set at 1773, 1873, 1973, and 2073 K for different models to study the temperature effect on the lithospheric thinning processes. Our end-member calculations show that with the bottom boundary raising the lithosphere can be thinned from a depth of 200 km to a depth of between 100 and 126.25 km. The thinning rates are at mm/y order of magnitude, and the thinning timescale is about 10 Ma. | QIAO YanChao GUO ZiQi SHI YaoLin | 2013 | Science China Earth Sciences2013，56，5： | 7 |
| 2 | Strategies for improving the lithium-storage performance of 2D nanomaterials显示文摘2D nanomaterials, including graphene, transition metal oxide(TMO) nanosheets, transition metal dichalcogenide(TMD) nanosheets, etc., have offered an appealing and unprecedented opportunity for the development of high-performance electrode materials for lithium-ion batteries(LIBs). Although significant progress has been made on 2D nanomaterials for LIB applications in the recent years, some major challenges still exist for the direct use of these sheet-like nanomaterials, such as their serious self-agglomerating tendency during electrode fabrication and low conductivity as well as the large volume changes over repeated charging–discharging cycles for most TMOs/TMDs, which have resulted in large irreversible capacity, low initial Coulombic efficiency and fast capacity fading. To address these issues,considerable progress has been made in the exploitation of 2D nanosheets for enhanced lithium storage. In this review, we intend to summarize the recent progress on the strategies for enhancing the lithium-storage performance of 2D nanomaterials, including hybridization with conductive materials, surface/edge functionalization and structural optimization. These strategies for manipulating the structures and properties of 2D nanomaterials are expected to meet the grand challenges for advanced nanomaterials in clean energy applications and thus provide access to exciting materials for achieving high-performance next-generation energy-storage devices. | Jun Mei Yuanwen Zhang Ting Liao Ziqi Sun Shi Xue Dou | 2018 | National Science Review2018，5，3： | 5 |

| 4 | Swarming Responsive Photonic Nanorobots for Motile-Targeting Microenvironmental Mapping and Mapping-Guided Photothermal Treatment显示文摘Micro/nanorobots can propel and navigate in many hard-to-reach biological environments,and thus may bring revolutionary changes to biomedical research and applications.However,current MNRs lack the capability to collectively perceive and report physicochemical changes in unknown microenvironments.Here we propose to develop swarming responsive photonic nanorobots that can map local physicochemical conditions on the fly and further guide localized photothermal treatment.The RPNRs consist of a photonic nanochain of periodically-assembled magnetic Fe_(3)O_(4)nanoparticles encapsulated in a responsive hydrogel shell,and show multiple integrated functions,including energetic magnetically-driven swarming motions,bright stimuli-responsive structural colors,and photothermal conversion.Thus,they can actively navigate in complex environments utilizing their controllable swarming motions,then visualize unknown targets(e.g.,tumor lesion)by collectively mapping out local abnormal physicochemical conditions(e.g.,pH,temperature,or glucose concentra-tion)via their responsive structural colors,and further guide external light irradiation to initiate localized photothermal treatment.This work facilitates the development of intelligent motile nanosensors and versatile multifunctional nanotheranostics for cancer and inflam-matory diseases. | Luolin Li Zheng Yu Jianfeng Liu Manyi Yang Gongpu Shi Ziqi Feng Wei Luo Huiru Ma Jianguo Guan Fangzhi Mou | 2023 | Nano-Micro Letters2023，15，9： | 3 |
| 5 | The Environmental Functions and Ecological Effects of Organic Carbon in Silt显示文摘Silt is a kind of unconsolidated sediment consisting of fine particles;silt is generally deposited across wide areas on the surfaces of drainages and in oceans under static or slow-hydrodynamic conditions. The organic carbon(OC) in silt has multiple essential environmental functions. This paper elaborates the morphological and environmental indication functions of OC in silt, and the effect of its own migration and transformation on environmental deterioration. Organic carbon exists in silt in two forms, free and mineral-binding. Meanwhile, based on its formation and structure, OC can be divided into light and heavy fraction of OC. Environmental information including data related to paleoclimates, ancient levels of productivity level, and variations in regional organism abundance can be discovered from total organic carbon, the C/N ratio, and OC isotope content. Degradation of OC is believed to participate in the emission of greenhouse gases, release of heavy metals and other contaminants. Finally, from the view of silt deposition, the possible influence of complex water-rock interaction in which OC is involved during the evolution of silt to a clayey aquitard on the hydrochemical composition of groundwater is discussed, which provides a new perspective for future research on the carbon cycle in nature. | Rui Liu Teng Ma Wenkai Qiu Ziqi Peng Chenxuan Shi | 2020 | Journal of Earth Science2020，31，4： | 2 |
| 6 | QTL mapping of quality traits in peanut using whole-genome resequencing显示文摘Oil and protein content and fatty acid composition are quality traits in peanut.Elucidating the genetic mechanisms underlying these traits may help researchers to obtain improved cultivars by molecular breeding.Whole-genome resequencing of a recombinant inbred population of 318 lines was performed to construct a high-density linkage map and identify QTL for peanut quality.The map,containing 4561 bin markers,covered 2032 c M with a mean marker density of 0.45 c M.A total of 110 QTL for oil and protein content,and fatty acid composition were mapped on the 18 peanut chromosomes.The QTL q A05.1 was detected in four environments and showed a major phenotypic effect on the contents of oil,protein,and six fatty acids.The genomic region spanned by q A05.1,corresponding to a physical interval of approximately 1.5 Mb,contains two SNPs polymorphic between the parents that could cause missense mutations.The two SNP sites were employed as KASP markers and validated using lines with extremely high and low oil contents.These sites may be useful in the marker-assisted breeding of peanut cultivars with high oil contents. | Ziqi Sun Feiyan Qi Hua Liu Li Qin Jing Xu Lei Shi Zhongxin Zhang Lijuan Miao Bingyan Huang Wenzhao Dong Xiao Wang Mengdi Tian Jingjing Feng Ruifang Zhao Xinyou Zhang Zheng Zheng | 2022 | The Crop Journal2022，10，1： | 2 |

| 9 | Cell deaths:Involvement in the pathogenesis and intervention therapy of COVID-19显示文摘The current pandemic of coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus 2(SARSCoV-2)infection has dramatically influenced various aspects of the world.It is urgent to thoroughly study pathology and underlying mechanisms for developing effective strategies to prevent and treat this threatening disease.It is universally acknowledged that cell death and cell autophagy are essential and crucial to maintaining host homeostasis and participating in disease pathogenesis.At present,more than twenty different types of cell death have been discovered,some parts of which have been fully understood,whereas some of which need more investigation.Increasing studies have indicated that cell death and cell autophagy caused by coronavirus might play an important role in virus infection and pathogenicity.However,the knowledge of the interactions and related mechanisms of SARS-CoV-2 between cell death and cell autophagy lacks systematic elucidation.Therefore,in this review,we comprehensively delineate how SARS-CoV-2 manipulates diverse cell death(including apoptosis,necroptosis,pyroptosis,ferroptosis,and NETosis)and cell autophagy for itself benefits,which is simultaneously involved in the occurrence and progression of COVID-19,aiming to provide a reasonable basis for the existing interventions and further development of novel therapies. | Xue Li Ziqi Zhang Zhenling Wang Pedro Gutiérrez-Castrellón Huashan Shi | 2022 | Signal Transduction and Targeted Therapy2022，7，7： | 1 |

| 11 | Slurry-like hybrid electrolyte with high lithium-ion transference number for dendrite-free lithium metal anode显示文摘Lithium metal anode is regarded as the ultimate choice for next-generation energy storage systems,due to the lowest negative electrochemical potential and super high theoretical specific capacity.However,the growth of lithium dendrite during the cycling process is still one of the most critical bottlenecks for its application.In this work,a slurry-like hybrid electrolyte is proposed towards the application for lithium metal anode,which is composed of a liquid electrolyte part and a nanometric silane-Al2O3 particle part.The hybrid electrolyte shows high ionic conductivity(3.89×10-3 S cm-1 at 25℃)and lithium-ion transference number(0.88).Especially,the resistance of hybrid electrolyte decreases compared to that of liquid electrolyte,while the viscosity of hybrid electrolyte increases.It is demonstrated that the hybrid electrolyte can effectively suppress the growth of lithium dendrite.Stable cycling of Li/Li cells at a current density up to 1 mA cm-2 is possible.The hybrid electrolyte helps to uniform the lithium ion flux inside the battery and partly comes from the formation of a rigid and highly conductive hybrid interfacial layer on the surface of lithium metal.This work not only provides a fresh way to stabilize lithium metal anode but also sheds light on further research for electrolyte optimization and design of lithium metal battery system. | Hewei Xu Ying He Zibo Zhang Junli Shi Pingying Liu Ziqi Tian Kan Luo Xiaozhe Zhang Suzhe Liang Zhaoping Liu | 2020 | Journal of Energy Chemistry2020，29，9： | 1 |

| 13 | Confined Pyrolysis Synthesis of Well-dispersed Cobalt Copper Bimetallic Three-dimensional N-Doped Carbon Framework as Efficient Water Splitting Electrocatalyst显示文摘Hydrogen is one of the most desirable alternatives to fossil fuels due to its renewability and large energy density.Electrochemical water splitting,as an environmental-friendly way to produce H_(2) of high-purity,is drawing more and more attention.Conductive nitrogen-doped carbon frameworks derived from metal-organic frameworks(MOFs)have been applied as promising electrocatalysts thanks to their superior conductivity,numerous active sites and hierarchical porous structures.However,traditional uncontrolled pyrolysis will lead to aggregation or fusion of the metal sites in MOFs or even cause collapse of the three-dimensional structures.Herein,we provide a confinement pyrolysis strategy to fabricate a CoCu bimetallic N-doped carbon framework derived from MOFs,which exhibits satisfactory catalytic performance with overpotentials of 199 mV towards hydrogen evolution reaction and 301 mV towards oxygen evolution reaction to reach 10 mA/cm^(2) in an alkaline solution.This work presents further inspirations for preserving the original skeleton of MOFs during high temperature pyrolysis in order to obtain more stable and efficient electrocatalyst. | ZHANG Ziqi WANG Hanbo LI Yuxin XIE Minggang LI Chunguang LU Haiyan PENG Yu SHI Zhan | 2022 | Chemical Research in Chinese Universities2022，38，3： | 1 |

| 16 | Most root-derived carbon inputs do not contribute to long-term global soil carbon storage显示文摘Plant root-derived carbon(C)inputs(I_(root))are the primary source of C in mineral bulk soil.However,a fraction of I_(root)may lose quickly(I_(loss),e.g.,via rhizosphere microbial respiration,leaching and fauna feeding)without contributing to long-term bulk soil C storage,yet this loss has never been quantified,particularly on a global scale.In this study we integrated three observational global data sets including soil radiocarbon content,allocation of photo synthetically assimilated C,and root biomass distribution in 2,034 soil profiles to quantify I_(root)and its contribution to the bulk soil C pool.We show that global average I_(root)in the 0-200 cm soil profile is 3.5 Mg ha^(-1)yr^(-1),~80%of which(i.e.,I_(loss))is lost rather than co ntributing to long-term bulk soil C storage.I_(root)decreases exponentially with soil depth,and the top 20 cm soil contains>60%of total I_(root).Actual C input contributing to long-term bulk soil storage(i.e.,I_(root)-I_(loss))shows a similar depth distribution to I_(root).We also map I_(loss)and its depth distribution across the globe.Our results demonstrate the global significance of direct C losses which limit the contribution of I_(root)to bulk soil C storage;and provide spatially explicit data to facilitate reliable soil C predictions via separating direct C losses from total root-derived C inputs. | Guocheng WANG Liujun XIAO Ziqi LIN Qing ZHANG Xiaowei GUO Annette COWIE Shuai ZHANG Mingming WANG Songchao CHEN Ganlin ZHANG Zhou SHI Wenjuan SUN Zhongkui LUO | 2023 | Science China Earth Sciences2023，66，5： | 0 |
| 17 | Coupling simulation of fluid structure interaction in the stirred vessel with a pitched blade turbine显示文摘The interaction between fluid and a down-pumping pitched blade turbine fixed with a flexible shaft in the stirred vessel, as a typical fluid structure interaction phenomenon, was simulated by coupling the Computational Fluid Dynamics and Computational Structural Dynamics. Based on the verification of the simulated impeller torque and dimensionless shaft bending moment with experimental result, the dimensionless shaft bending moment and various loads acting on impeller(including lateral force, axial force and bending moment) were discussed in detail. By separating and extracting the fluid and structural components from those loads, the results show that the shaft bending moment mainly results from the lateral force on impeller although the axial force on impeller is much larger. The impeller mass imbalance increases the shaft bending moment and the lateral force on impeller, but has little influence on the axial force and bending moment acting on impeller. The dominant frequencies of impeller forces are macro-frequency, speed frequency and blade passing frequency, and are associated with the impeller mass imbalance. | Yangyang Liang Zhengming Gao Dai'en Shi Wanli Zhao Ziqi Cai | 2018 | Chinese Journal of Chemical Engineering2018，26，5： | 0 |
| 18 | Identification of a stable major QTL for fresh-seed germination on chromosome Arahy.04 in cultivated peanut(Arachis hypogaea L.)显示文摘Fresh-seed germination(FSG)impairs peanut production,especially in areas where the peanut harvest season coincides with rainy weather.Developing FSG-resistant cultivars by molecular breeding is expected to mitigate yield loss and quality impairment caused by FSG.However,the genetic control of FSG awaits elucidation.In this study,FSG at 1,3,5,7,and 9 days post-imbibition in three environments were tested,and quantitative-trait loci(QTL)associated with FSG were mapped in a peanut recombinant inbred line population by leveraging existing high-density peanut genetic maps.Of 24 QTL identified in 13 linkage groups,qFSGA04 was a stable major QTL on linkage group 04(LG04).It was consistently detected in five germination stages and three environments.By designing and validating DNA markers in the confidence interval of qFSGA04,we identified one single-nucleotide polymorphism and one In Del closely associated with FSG that could be used as linked markers for FSG resistance in peanut breeding. | Maoning Zhang Qing Zeng Hua Liu Feiyan Qi Ziqi Sun Lijuan Miao Xiaona Li Chenyu Li Debing Liu Junjia Guo Mengyuan Zhang Jing Xu Lei Shi Mengdi Tian Wenzhao Dong Bingyan Huang Xinyou Zhang | 2022 | The Crop Journal2022，10，6： | 0 |

| 20 | Volumetric Imaging of Neural Activity by Light Field Microscopy显示文摘Recording the highly diverse and dynamic activities in large populations of neurons in behaving animals is crucial for a better understanding of how the brain works.To meet this challenge,extensive efforts have been devoted to developing functional fluorescent indicators and optical imaging techniques to optically monitor neural activity.Indeed,optical imaging potentially has extremely high throughput due to its non-invasive access to large brain regions and capability to sample neurons at high density,but the readout speed,such as the scanning speed in two-photon scanning microscopy,is often limited by various practical considerations.Among different imaging methods,light field microscopy features a highly parallelized 3D fluorescence imaging scheme and therefore promises a novel and faster strategy for functional imaging of neural activity.Here,we briefly review the working principles of various types of light field microscopes and their recent developments and applications in neuroscience studies.We also discuss strategies and considerations of optimizing light field microscopy for different experimental purposes,with illustrative examples in imaging zebrafish and mouse brains. | Lu Bai Zhenkun Zhang Lichen Ye Lin Cong Yuchen Zhao Tianlei Zhang Ziqi Shi Kai Wang | 2022 | Neuroscience Bulletin2022，38，12： | 0 |
