1Review and prospect of NiCo_(2)O_(4)-based composite materials for supercapacitor electrodes显示文摘Supercapacitors known as typical electrochemical capacitors have been considered as one of the most promising candidates of energy storage systems owing to their advantages such as high-power density,long life span and lower production cost.The electrode materials play a crucial role on properties of supercapacitors.Hence,many researches have been focused on the development of novel electrode materials for high-performance supercapacitors.NiCo_2O_4as supercapacitor electrode material has drawn more and more attentions in recent years due to its outstanding advantages,such as high theoretical capacity,low cost,natural abundance and easy of synthesis.However,the NiCo_2O_4always suffer from severe capacity deterioration because of the low electrical conductivity and small surface area.Hence,it is necessary to systematically and comprehensively summarize the progress in understanding and modifying NiCo_2O_4-based materials from various aspects.In this review,the structure and synthesis method of NiCo_2O_4-based materials are discussed in detail.And then,the major goal of this review is to highlight new progress in using proposed strategies to improve the cycling stability and rate capacity of NiCo_2O_4-based materials,including synthesis,control of special morphologies and design of composite materials.Finally,an insight into the future research and development of Ni Co_2O_4-based materials for supercapacitors is prospected.Yanmei Li Xiao Han Tingfeng Yi Yanbing He Xifei Li 2019Journal of Energy Chemistry2019,28,4:14
2Depositional 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
3New discovery of seafloor hydrothermal activity on the Indian Ocean Carlsberg Ridge and Southern North Atlantic Ridge-progress during the 26th Chinese COMRA cruise显示文摘The 26th Chinese COMRA (China Ocean Mineral Resources Research & Development Association) cruise was an important cruise. The Carlsberg Ridge (CR) of the Northwest Indian Ocean and the North Atlantic Ridge (NAR), in which less investigation has been carried out for hydrothermal activities, were investigated and studied during the first two legs of the 26th COMRA cruise. During the first leg, we found one hydrothermal activity field located in the CR at 3.5 -3.8 N on the Northwest Indian Ocean Ridge (NWIR), and sampled seafloor polymetallic sulfide deposits where only abnormalities were found before. During the second leg, we found a new hydrothermal anomaly field located in the NAR at 4 -7 N. The discovery of two hydrothermal and anomaly fields filled in the gap of hydrothermal investigation and study in the corresponding regions for China.TAO Chunhui WU Guanghai DENG Xianming QIU Zhongyan HAN Chenhua LONG Yanmei 2013Acta Oceanologica Sinica2013,32,8:5
4Inflammation-induced CD69^+ Kupffer cell feedback inhibits T cell proliferation via membrane-bound TGF-β1显示文摘Kupffer cells,tissue-resident macrophage lineage cell,are enriched in vertebrate liver.The mouse F4/80^+ Kupffer cells have been subclassified into two subpopulations according to their phenotype and function:CD68^+ subpopulation with potent reactive oxygen species(ROS) production and phagocytic capacities,and CD11b^+ subpopulation with a potent capacity to produce T helper 1 cytokines.In addition,CD11b^+ Kupffer cells/macrophages may be migrated from the bone marrow or spleen,especially in inflammatory conditions of the liver.For analyzing diverse Kupffer cell subsets,we infected mice with Listeria monocytogenes and analyzed the phenotype variations of hepatic Kupffer cells.During L.monocytogenes infection,hepatic CD69^+ Kupffer cells were significantly induced and expanded,and CD69^+ Kupffer cells expressed higher level of CD11 b,and particularly high level of membrane-bound TGF-β1(mTGF-β1) but lower level of F4/80.We also found that clodronate liposome administration did not eliminate hepatic CD69^+ Kupffer cell subset.We consider the hepatic CD69^+ Kupffer cell population corresponds to CD11b^+Kupffer cells,the bone marrow-derived population.Hepatic CD69^+ Kupffer cells suppressed Ag-nonspecific and OVA-specific CD4 T cell proliferation through mTGF-β1 both in vitro and in vivo,meanwhile,they did not interfere with activation of CD4 T cells.Thus,we have identified a new subset of inflammation-induced CD69^+ Kupffer cells which can feedback inhibit CD4 T cell response via cell surface TGF-β1 at the late stage of immune response against infection.CD69^+ Kupffer cells may contribute to protect host from pathological injure by preventing overactivation of immune response.Xiang Zhang Zhengping Jiang Yan Gu Yanfang Liu Xuetao Cao Yanmei Han 2016Science China(Life Sciences)2016,59,12:5
5High-performance polarization management devices based on thin-film lithium niobate显示文摘High-speed polarization management is highly desirable for many applications,such as remote sensing,telecommunication,and medical diagnosis.However,most of the approaches for polarization management rely on bulky optical components that are slow to respond,cumbersome to use,and sometimes with high drive voltages.Here,we overcome these limitations by harnessing photonic integrated circuits based on thin-film lithium niobate platform.We successfully realize a portfolio of thin-film lithium niobate devices for essential polarization management functionalities,including arbitrary polarization generation,fast polarization measurement,polarization scrambling,and automatic polarization control.The present devices feature ultra-fast control speeds,low drive voltages,low optical losses and compact footprints.Using these devices,we achieve high fidelity polarization generation with a polarization extinction ratio up to 41.9 dB and fast polarization scrambling with a scrambling rate up to 65 Mrad s−1,both of which are best results in integrated optics.We also demonstrate the endless polarization state tracking operation in our devices.The demonstrated devices unlock a drastically new level of performance and scales in polarization management devices,leading to a paradigm shift in polarization management.Zhongjin Lin Yanmei Lin Hao Li Mengyue Xu Mingbo He Wei Ke Heyun Tan Ya Han Zhaohui Li Dawei Wang X.Steve Yao Songnian Fu Siyuan Yu Xinlun Cai 2022Light(Science & Applications)2022,11,5:3

8Tuning Curves of 70 MHz Frequency Differences for HeNe Standing-Wave Lasers显示文摘Two experiments are reported on measuring the variation of the frequency differences for the st&nding wave lasers with tuning the cavity length.The frequency difference is caused by an intracavity quartz crystal plate(laser mode splitting technology).The relative variation of the frequency difference during the tuning are about 10^(-3) order from the edge to the centre of lasing bandwidth.The diiFerence between the largest and the smallest frequency differences is two orders as large as that of ring lasers.ZHANG Shulian HAN Yanmei 1993Chinese Physics Letters1993,10,12:2
9Determination of minimum overburden depth for underwater shield tunnel in sands:Comparison between circular and rectangular tunnels显示文摘With the development of global urbanization,the utilization of underground space is more critical and attractive for civil purposes.Various shapes of shield tunnels have been gradually proposed to cope with different geological conditions and service purposes of underground structures.Generally,reducing the burial depth of shield tunnel is conducive to construction and cost saving.However,extremely small overburden depth cannot provide sufficient uplift resistance to maintain the stability and serviceability of the tunnel.To this end,this paper firstly reviewed the status of deriving the minimum sand over-burden depth of circular shield tunnel using mechanical equilibrium(ME)method.It revealed that the estimated depth is rather conservative.Then,the uplift resistance mechanism of both circular and rectangular tunnels was deduced theoretically and verified with the model tests.The theoretical uplift resistance is consistent with the experimental values,indicating the feasibility of the proposed equations.Furthermore,the determination of the minimum soil overburden depth of rectangular shield tunnel under various working conditions was presented through integrated ME method,which can provide more reasonable estimations of suggested tunnel burial depth for practical construction.Additionally,optimizations were made for calculating the uplift resistance,and the soil thickness providing uplift resistance is suggested to be adjusted according to the testing results.The results can provide reference for the design and construction of various shapes of shield tunnels in urban underground space exploitation.Weixin Sun Fucheng Han Hanlong Liu Wengang Zhang Yanmei Zhang Weijia Su Songlin Liu 2023Journal of Rock Mechanics and Geotechnical Engineering2023,15,7:2
10Experimental analysis on the interaction between underground structures and sand layer under groundwater level change显示文摘Groundwater level change stands a momentous role in affecting the geotechnical construction stability and safety of underground structures.Global warming and active underground construction cause conspicuous changes in the groundwater level,which further leaves an impact on the underground structures’serviceability.To reveal the interaction between underground structure and soil under groundwater level change in the sand layer,model tests of circular transportation tunnel and rectangular utility tunnel were carried out.With the self-designed experimental equipment and innovative experimental methods,the changes in tunnel stress,bending moment,buoyancy,and vertical displacement of the rise and drawdown of the groundwater level in the sand layer were studied.The results revealed the developments of concentrated structural forces during the rising and falling process of the groundwater water level,indi-cating critical locations that should be strengthened.Meanwhile,both tunnels showed the same movement trend:settling first,floating afterwards and settling at last.And it is concluded that no reduction is required when calculating buoyancy in sands using measured pore pressure.Conclusions can provide a notable reference for future related research and engineering designs.Hanlong Liu Weixin Sun Yanmei Zhang Wengang Zhang Fucheng Han Weijia Su 2023Underground Space2023,,3:1

12Synthesis and Electric Properties of Polyethylene Grlycol-modified Fly Ash Floating Bead/polyaniline Composites显示文摘Fly ash floating bead(FAFB) was modified by the nonionic surfactant polyethylene glycol(PEG) under various concentrations to improve its hydrophobility,and then PEG modified FAFB composited with polyaniline(FAFB-PEG/PAn) by emulsion polymerization method using different feed ratios of FAFBPEG.The chemical structure,phase structure,microstructure,conductivity,and dielectric properties were studied by FT-IR,XRD,SEM,four-probe technique,and LCR digital bridge,respectively.It was demonstrated that the optimal concentration of PEG was 1 mol/L and the corresponding grafting ratio was 1.42%.The phase structure of FAFB was not destroyed after modification by PEG,while the surface became smoother and could be coated by PAn successfully according to SEM technique.Compared to that of dodecylbenzenesulfonic acid doped PAn(PAn-DBSA),the conductivity of FAFB-PEG/PAn was decreased by 10-100 times after introduction of various amounts of FAFB-PEG,especially the value could be decreased to 0.01 S cm^(-1) if 50 wt%of FAFBPEG was provided.Additionally,the dielectric constant and loss factor of FAFB-PEG/PAn composites gradually decreased with increasing amount of FAFB-PEG in the frequency range of 100 KHz-2 MHz,namely,the dielectric constant could be still kept at 500 and correspondingly the loss factor decreased to 4.7 at 100 KHz if50 wt%of FAFB-PEG was provided.The leaking current phenomenon derived from PAn-DBSA could also be weakened by FAFB-PEG.雷西萍 HAN Ding WANG Yue SONG Xuefeng LIN Yanmei 2017Journal of Wuhan University of Technology(Materials Science)2017,32,1:1
