| 1 | Near-surface structure and energy characteristics of the Antarctic Circumpolar Current显示文摘Historical surface drifter observations collected from the Southern Ocean are used to study the near-surface structure,variability,and energy characteristics of the Antarctic Circumpolar Current(ACC).A strong,nearly zonal ACC combined with complex fronts dominates the circulation system in the Southern Ocean.Standard variance ellipses indicate that both the Agulhas Return Current and the East Australian Warm Current are stable supplements of the near-surface ACC,and that the anticyclonic gyre formed by the Brazil warm current and the Malvinas cold current is stable throughout the year.During austral winter,the current velocity increases because of the enhanced westerly wind.Aroused by the meridional motion of the ACC,the meridional velocity shows greater instability characteristics than the zonal velocity does over the core current.Additionally,the ACC exhibits an eastward declining trend in the core current velocity from southern Africa.The characteristics of the ACC are also argued from the perspective of energy.The energy distribution suggests that the mean kinetic energy(MKE),eddy kinetic energy(EKE),and EKE are strong over the core currents of the ACC.However,in contrast,EKE/MKE suggests there is much less(more)eddy dissipation in regions with strong(weak)energy distribution.Both meridional and zonal energy variations are studied to illustrate additional details of the ACC energy characteristics.Generally,all the energy forms except EKE/MKE present west-east reducing trends,which coincide with the velocity statistics.Eddy dissipation has a much greater effect on MKE in the northern part of the Southern Ocean. | GAO Libao YU Weidong WANG Haiyuan LIU Yanliang | 2013 | Advances in Polar Science2013,24,4: | 3 |
| 2 | Structure and seasonal variability of fronts in the Southeast Indian Ocean along sections from Fremantle, Australia to Antarctic Zhongshan Station显示文摘Four sections of expendable conductivity-temperature-depth(XCTD) profiles from Fremantle, Australia to Antarctic Zhongshan Station and Moderate Resolution Imaging Spectroradiometer-Aquarius(MODIS-A) sea surface temperature(SST) products were used to study the structure and seasonal variability of Southeast Indian Ocean fronts. Water mass analysis showed that surface water masses in the Southeast Indian Ocean were less salty in March than in November. Compared with November, the subtropical front(STF) moved southward about one degree of latitude in March, whereas seasonal variability of the subantarctic front(SAF) and polar front(PF) locations was not obvious. In March, the saline front moved northward about two degrees of latitude relative to the thermal front in the upper 100 m at the SAF, which was the northern boundary of subAntarctic surface water(SASW). Analysis of climatological SST gradients from the satellite data showed that regions of enhanced sea surface temperature(SST) gradients were collocated with frontal locations identified with the XCTD data using water mass criteria. The surface expression of the PF identified by the SST gradient was further south by about one degree of latitude relative to the subsurface expression of the PF identified by the northern boundary of cold water. | YANG Wei GAO Libao LI Ruixiang LIU Changjian YAN Jinhui | 2016 | Advances in Polar Science2016,27,1: | 2 |
| 3 | Multi-year assessment of paralytic shellfish toxins in hard clam species along the coastline of Jiangsu Province, China显示文摘Paralytic shellfish toxins(PSTs) are notorious neurotoxins that threaten public health and food safety worldwide.Although PST monitoring programs have recently been established throughout China, the profiles and variation of PSTs in important commercial clams(e.g., Mactra veneriformis, Ruditapes philippinarum, and Meretrix meretrix) along the Jiangsu Province coastline remain largely unexplored. In this study, a validated hydrophilic interaction liquid chromatography–tandem mass spectrometry(HILIC-MS/MS) method was used to examine PST profiles and levels in 540 clam samples from natural production areas along Jiangsu Province coastline during2014–2016. Although the PST levels(≤6.38 μg saxitotoxin equivalents(eq)/kg) were consistently below European Union regulatory limits(≤800 μg saxitotoxin eq/kg) during this time period, saxitotoxin, decarbamoylsaxitotoxin,and gonyautoxins 1 and 4 were detected, and nearly 40% of the samples were saxitotoxin-positive. The PST levels also varied significantly by seasons, with peak values observed in May during 2014–2016. This is the first systematic report of PSTs in clams from Jiangsu Province, and additional research and protective measures are needed to ensure the safety of clams harvested in this area. | Xinzhi Wang Hao Wu Ying Cheng Hongmei Wen Rui Liu Libao Wang Chenxiao Shan Chuan Chai | 2019 | Acta Oceanologica Sinica2019,38,2: | 1 |
| 4 | Effects of different root zone heating systems on the microclimate and crop development in solar greenhouses显示文摘Heating greenhouse is indispensable for plant development particularly in winter when the air temperature is lower.In that sense,root zone heating is more energy-saving than traditional air heating.The current work was devoted to the study of the effect of two root zone heating systems based on carbon crystal electrothermal film and low temperature hot water pipe on the microclimate and tomato yield in solar greenhouse.And their performance was tested in the coldest period of winter in Yongqing County of Hebei Province.The results showed that the use of root zone heating system can improve the average substrate temperature by 6.8℃.This microclimate improvement had a positive impact on tomato production.The output per square meter has increased by 19%compared to the unheated.It was also noted that the presence of root zone heating leads to a decrease in the development of disease in heated areas.Based on these results,the root zone heating system can be an effective method of improving the environmental temperature of crop plant,which is of great significance for increasing crop yield. | Fen He Jing Tian Liu Wang Yong Hou Fei Qi Yanping Zhang Libao Zhu Zhonghua Li | 2022 | International Journal of Agricultural and Biological Engineering2022,15,6: | 1 |
| 5 | Simulating the strong ground motion of the 2022 MS6.8 Luding,Sichuan,China Earthquake显示文摘Stochastic finite-fault simulations are effective for simulating ground motions and are widely used in engineering to determine the impacts of ground motion and develop relevant predictive equations.In this study,the source,path,and site amplification coefficient of western Sichuan Province,China,and stochastic finite-fault simulations were used to simulate the acceleration time series,Fourier amplitude spectra,and 5%damped response spectra of 28 strong-motion stations with rupture distances within 300 km of the 2022 MS6.8 Luding earthquake.The simulation results of 14 stations at rupture distances of 45-185 km match the observation.However,the simulation results of 3 near-and 6 far-field stations at rupture distances of 12-36 km and 222-286 km,respectively,were obviously deviated from the observations.Simulation results of the near-field stations are larger than the observations at high frequencies(>6 Hz).The discrepancy likely comes from the nonlinear site effect of near-field stations,which reduced the site amplification at high frequencies.Simulation result of the far-field stations is smaller than the observation at frequencies above 1 Hz.As these stations are located close to the Longmenshan Fault Zone(LFZ),thus,we obtained a new quality factor(Q)from data of historical events and stations located around LFZ.Using the new Q value,the discrepancies of the high-frequency simulation results of the far-field stations were corrected.This result indicated that the laterally varying Q values can be used to address the impact of strong crustal lateral heterogeneity on simulation. | Libao Zhang Lei Fu Aiwen Liu Su Chen | 2023 | Earthquake Science2023,36,4: | 1 |
| 6 | 3D Printing Engineered Multi-porous Cu Microelectrodes with In Situ Electro-Oxidation Growth of CuO Nanosheets for Long Cycle,High Capacity and Large Rate Supercapacitors显示文摘Developing excellent pseudocapacitive electrodes with long cycle,high areal capacity and large rate has been challenged.3 D printing is an additive manufacture technique that has been explored to construct microelectrodes of arbitrary geometries for high-energy–density supercapacitors.In comparison with conventional electrodes with uncontrollable geometries and architectures,3 D-printed electrodes possess unique advantage in geometrical shape,mechanical properties,surface area,especially in ion transport and charge transfer.Thus,a desirable 3 D electrode with ordered porous structures can be elaborately designed by 3 D printing technology for improving electrochemical capacitance and rate capability.In this work,a designed,monolithic and ordered multi-porous 3 D Cu conductive skeleton was manufactured through 3 D direct ink writing technique and coated with Cu O nanosheet arrays by an in situ electro-oxidation treatment.Benefiting from the highly ordered multiporous nature,the 3 D-structured skeleton can eff ectively enlarge the surface area,enhance the penetration of electrolyte and facilitate fast electron and ion transport.As a result,the 3 D-printed Cu deposited with electro-oxidation-generated CuO(3 DP Cu@Cu O)electrodes demonstrates an ultrahigh areal capacitance of 1.690 F cm^(-2)(38.79 F cm^(-3))at a large current density of 30 m A cm^(-2)(688.59 m A cm^(-3)),excellent lifespan of 88.20%capacitance retention after 10,000 cycles at 30 m A cm^(-2) and superior rate capability(94.31%retention,2-30 m A cm^(-2)).This design concept of 3 D printing multi-porous current collector with hierarchical active materials provides a novel way to build high-performance 3 D microelectrodes. | Tao Liu Yuejiao Chen Libao Chen | 2021 | Acta Metallurgica Sinica(English Letters)2021,34,1: | 1 |

| 9 | Fast ion diffusion alloy layer facilitating 3D mesh substrate for dendrite-free zinc-ion hybrid capacitors显示文摘Although aqueous zinc ion hybrid capacitors have advantageous integration of batteries and supercapacitors,they still suffer from the inherent problems of dendrite growth and interfacial side reactions on Zn anodes.Herein,a universal fast zinc-ion diffusion layer on a three-dimensional(3 D)mesh structure model is demonstrated to effectively improve Zn plating/stripping reversibility.The fast ion diffusion alloy layer accelerates the Zn^(2+)migration in an orderly manner to homogenize Zn^(2+)flux and overcomes the defects of the commercial mesh substrate,effectively avoiding dendrite growth and side reactions.Consequently,the proof-of-concept silver-zinc alloy modified stainless steel mesh delivers superb reversibility with the high coulombic efficiency over 99.4%at 4 mA cm^(-2)after 1600 cycles and excellent reliability of over 830 h at 1 mA cm^(-2),Its feasibility is also evidenced in commercial zinc ion hybrid capacitors with activated carbon as the cathode.This work enriches the fundamental comprehension of fast zinc-ion diffusion layer combined with a 3 D substrate on the Zn deposition and opens a universal approach to design advanced host for Zn electrodes in zinc ion hybrid capacitors. | Huaming Yu Quanyu Li Wen Liu Han Wang Xuyan Ni Qiwen Zhao Weifeng Wei Xiaobo Ji Yuejiao Chen Libao Chen | 2022 | Journal of Energy Chemistry2022,31,10: | 0 |
| 10 | Crosslinked solubilizer enables nitrate-enriched carbonate polymer electrolytes for stable,high-voltage lithium metal batteries显示文摘High-voltage lithium metal batteries(LMBs)have been considered promising next-generation highenergy-density batteries.However,commercial carbonate electrolytes can scarcely be employed in LMBs owing to their poor compatibility with metallic lithium.N,N-dimethylacrylamide(DMAA)-a crosslinkable solubilizer with a high Gutmann donor number-is employed to facilitate the dissolution of insoluble lithium nitrate(LiNO3)in carbonate-based electrolytes and to form gel polymer electrolytes(GPEs)through in situ polymerization.The Lit solvation structure of the GPEs is regulated using LiNO3 and DMAA,which suppresses the decomposition of LiPFe and facilitates the formation of an inorganic-rich solid electrolyte interface.Consequently,the Coulombic efficiency(CE)of the LillCu cell assembled with a GPE increases to 98.5%at room temperature,and the high-voltage LillNCM622 cell achieves a capacity retention of 80.1%with a high CE of 99.5%after 400 cycles.The bifunctional polymer electrolytes are anticipated to pave the way for next-generation high-voltage LMBs. | Chuyang Jing Kuan Dai Dong Liu Wenran Wang Libao Chen Chunxiao Zhang Weifeng Wei | 2024 | Science Bulletin2024,69,2: | 0 |
| 11 | Analysis of faulting destruction and water supply pipeline damage from the first mainshock of the February 6,2023 Türkiye earthquake doublet显示文摘In 2023,two consecutive earthquakes exceeding a magnitude of 7 occurred in Türkiye,causing severe casualties and economic losses.The damage to critical urban infrastructure and building structures,including highways,railroads,and water supply pipelines,was particularly severe in areas where these structures intersected the seismogenic fault.Critical infrastructure projects that traverse active faults are susceptible to the influence of fault movement,pulse velocity,and ground motions.In this study,we used a unique approach to analyze the acceleration records obtained from the seismic station array(9 strong ground motion stations)located along the East Anatolian Fault(the seismogenic fault of the MW7.8 mainshock of the 2023 Türkiye earthquake doublet).The acceleration records were filtered and integrated to obtain the velocity and displacement time histories.We used the results of an on-site investigation,jointly conducted by China Earthquake Administration and Türkiye’s AFAD,to analyze the distribution of PGA,PGV,and PGD recorded by the strong motion array of the East Anatolian Fault.We found that the maximum horizontal PGA in this earthquake was 3.0 g,and the maximum co-seismic surface displacement caused by the East Anatolian Fault rupture was 6.50 m.As the fault rupture propagated southwest,the velocity pulse caused by the directional effect of the rupture increased gradually,with the maximum PGA reaching 162.3 cm/s.We also discussed the seismic safety of critical infrastructure projects traversing active faults,using two case studies of water supply pipelines in Türkiye that were damaged by earthquakes.We used a three-dimensional finite element model of the PE(polyethylene)water pipeline at the Islahiye State Hospital and fault displacement observations obtained through on-site investigation to analyze pipeline failure mechanisms.We further investigated the effect of the fault-crossing angle on seismic safety of a pipeline,based on our analysis and the failure performance of the large-diameter Thames Water pipeline during the 1999 Kocaeli earthquake.The seismic method of buried pipelines crossing the fault was summarized. | Xiaoqing Fan Libao Zhang Juke Wang Yefei Ren Aiwen Liu | 2024 | Earthquake Science2024,37,1: | 0 |
| 12 | Sodiophilic and conductive carbon cloth guides sodium dendrite-free Na metal electrodeposition显示文摘Sodium metal battery(SMB)technology is one of the most promising candidates for next-generation rechargeable energy storage systems due to its high theoretical capacity and economical costeffectiveness.Unfortunately,its practical implementation is hindered by several challenges including short life-span and fast capacity decay,which is closely related to the uncontrollable generation of the sodium dendrites.Herein,a nitrogen and oxygen co-doped three-dimensional carbon cloth with hollow tubular fiber units was constructed as the host material for Na plating(Na@CC)to tackle these challenges.The obtained composite electrode can effectively reduce the nucleation overpotential of Na,guide the homogeneous Na^(+)flux,increase the kinetics of Na electrodeposition,lower the effective current density and eventually suppress the formation of electrochemically inactive Na dendrites.As a result,batteries built with the Na@CC composites exhibited stable long-term cycling stability.To gain an in-depth and comprehensive understanding of such phenomena,non-destructive and three-dimensional synchrotron X-ray tomography was employed to investigate the cycled batteries.Moreover,the COMSOL Multiphysics simulation was further employed to reveal the Na electrodeposition mechanisms.The current work not only showcases the feasibility of currently proposed sodiophilic 3 D Na@CC composite electrode but also provides fundamental insights into the underlying working mechanisms that govern its outstanding electrochemical performance. | Haijun Liu Markus Osenberg Ling Ni André Hilger Libao Chen Dong Zhou Kang Dong Tobias Arlt Xiayin Yao Xiaogang Wang Ingo Manke Fu Sun | 2021 | Journal of Energy Chemistry2021,30,10: | 0 |

| 14 | Vertical structure of low-level atmosphere over the southeast Indian Ocean fronts显示文摘During the 25th Chinese National Antarctic Research Expedition,GPS radiosondes were launched to detect the atmospheric vertical structure over the southeast Indian Ocean frontal region.Some low-level characteristics along the cruise are studied based on in-situ observation.The observations reveal that vertical distributions of the low-level wind field and air temperature field on both sides of the Subantarctic Front are very different.A stronger(weaker) vertical gradient is on the cold(warm) side,which demonstrates that the mid-latitude ocean-atmosphere interaction is active in the southeast Indian Ocean frontal region.A low-level jet is observed over the Subantarctic Front,with speed up to 14 m.s-1.For the Antarctic polar front,low-level wind speed near the sea surface is greater than that aloft,in contrast with the situation of the Subantarctic Front.Comparing satellite remote sensing data and widely-used reanalysis datasets with our in-situ observations,differences of varying magnitudes are found.Air temperature from Atmospheric Infrared Sounder(AIRS) data has a limited difference.The European Center for Medium Range Weather Forecasts Interim Re-Analysis(ERA Interim) dataset is much more consistent with the observations than the National Centers for Environmental Prediction/National Center for Atmospheric Research(NCEP/NCAR) Reanalysis 1 in the southeast Indian Ocean frontal region. | FENG Lin LIU Lin GAO Libao YU Weidong | 2012 | Advances in Polar Science2012,23,3: | 0 |
| 15 | The F5 gene predicts poor prognosis of patients with gastric cancer by promoting cell migration identified using a weighted gene co-expression network analysis显示文摘Distal gastric cancer(DGC)is a subgroup of gastric cancer(GC),which has different molecular characteristics from proximal gastric cancer(PGC).These differences result in different overall survival(OS)rates;however,data pertaining to the survival rate in PGC or DGC are contradictory.This suggests that the location of GC is not the unique cause of the different survival rates,while the molecular characteristics might be more important factors determining the prognosis of DGC.Therefore,the aim of this study was to discover key prognostic factors in DGC using bioinformatic methods and to explore the potential molecular mechanism.The Cancer Genome Atlas(TCGA)public database was employed to screen data relating to DGC,and we conducted a weighted gene co-expression network analysis(WGCNA)on DGC patient samples to establish co-expression modules.High-weight genes(hub genes)in a dominant color module were identified.In vitro experiments and gene set enrichment analyses(GSEA)were carried out to elucidate the potential molecular mechanism.In this study,139 DGC samples were enrolled to perform a co-expression analysis.According to the correlation between gene modules and clinical characteristics,the royal blue module related to stage M of DGC was screened,and a survival analysis was conducted to show that highcoagulation-factor V(F5)expression was related to the short OS of patients with GC.In vitro experiments confirmed that F5 could promote the migration of GC cells.GSEA suggested that F5 might have affected the prognosis of GC by modulating the activities of the Wnt and/or the TGF-βsignaling pathways.Our results indicated that high F5 expression predicts poor prognosis of patients with DGC,and it functions probably by promoting cell migration through the Wnt and/or the TGF-βsignaling pathways. | MENGYI TANG BOWEN YANG CHUANG ZHANG CHAOXU ZHANG DAN ZANG LIBAO GONG YUNPENG LIU ZHI LI XIUJUAN QU | 2021 | BIOCELL2021,45,4: | 0 |

| 17 | Degradation characteristics of insulation near aluminium foil edges inside dry-type bushing cores under electrothermal compound stress显示文摘Insulation breakdown of dry-type valve-side bushing cores under electrothermal compound stress has become a key factor limiting the safe and stable operation of the converter transformer.Based on slices of the real bushing core,it is observed for the first time that fold,peeling off,and fracture defects exist near the aluminium(Al)foil edge,accompanied by many metal spikes with a curvature radius<4μm.Coupled with a capacitor screen thickness of∼2 mm,an electrical tree model is designed to simulate insulation defects near aluminium foil edges inside dry-type bushing cores,whose insulation degradation characteristics under electrothermal compound stress are investigated accordingly.The results show that high temperature significantly increases the dielectric loss heat energy density and Joule heat energy density,accelerating the insulation degradation near Al foil edges.The parallel crepe paper interface significantly accelerates the growth of electrical trees under AC-superimposed positive DC voltage,while this effect is not significant under AC voltage.As the crepe paper consists of wooden fibres of 10μm diameter,the electrical trees tend to grow along interfaces between fibres and epoxy resin to form“feathery”electrical trees in epoxy resinimpregnated paper samples. | Ming Chen Xuandong Liu Yuhang Shao Gaoyi Shang Qiaogen Zhang Hao Tang Libao Liu | 2022 | High Voltage2022,7,6: | 0 |
