1To inhibit coffee ring effect in inkjet printing of light-emitting polymer films by decreasing capillary force显示文摘Polymer thin film with uniform thickness and flat surface profile is the key point for polymer light emitting diodes(PLEDs) by inkjet printing. However, the coffee ring effect is usually observed due to the mismatch between the evaporation of the solvent and the decrease of solution volume, which promotes the formation of radial flow from the interior of the drop to the edge. In this paper, coffee ring effects of inkjet printed poly(spirobifluorene) films were proposed to be restrained by decreasing capillary force by adding co-solvent with high boiling point and high viscosity to the main solvent. The low evaporation rate of the co-solvent can reduce the driving force of the radial flow; meanwhile the high viscosity of the co-solvent can increase the resistance of the radial flow. Thus, polymer films with improve uniformity can be obtained due to the suppression of the radial flow. The device performance was greatly improved under the condition of proper film thickness and film uniformity and the maximum luminous efficiency of devices with inkjet printed poly(spirobifluorene) can reach 80% of the spin-coated devices.Xinhong Yu Rubo Xing Zhongxiang Peng Yangming Lin Zhonghui Du Junqiao Ding Lixiang Wang Yanchun Han 2019Chinese Chemical Letters2019,30,1:4
2How does the Indian Ocean subtropical dipole trigger the tropical Indian Ocean dipole via the Mascarene high?显示文摘The variation in the Indian Ocean is investigated using Hadley center sea surface temperature(SST)data during the period 1958–2010.All the first empirical orthogonal function(EOF)modes of the SST anomalies(SSTA)in different domains represent the basin-wide warming and are closely related to the Pacific El Ni o–Southern Oscillation(ENSO)phenomenon.Further examination suggests that the impact of ENSO on the tropical Indian Ocean is stronger than that on the southern Indian Ocean.The second EOF modes in different domains show different features.It shows a clear east-west SSTA dipole pattern in the tropical Indian Ocean(Indian Ocean dipole,IOD),and a southwest-northeast SSTA dipole in the southern Indian Ocean(Indian Ocean subtropical dipole,IOSD).It is further revealed that the IOSD is also the main structure of the second EOF mode on the whole basin-scale,in which the IOD pattern does not appear.A correlation analysis indicates that an IOSD event observed during the austral summer is highly correlated to the IOD event peaking about 9 months later.One of the possible physical mechanisms underlying this highly significant statistical relationship is proposed.The IOSD and the IOD can occur in sequence with the help of the Mascarene high.The SSTA in the southwestern Indian Ocean persists for several seasons after the mature phase of the IOSD event,likely due to the positive wind–evaporation–SST feedback mechanism.The Mascarene high will be weakened or intensified by this SSTA,which can affect the atmosphere in the tropical region by teleconnection.The pressure gradient between the Mascarene high and the monsoon trough in the tropical Indian Ocean increases(decreases).Hence,an anticyclone(cyclone)circulation appears over the Arabian Sea-India continent.The easterly or westerly anomalies appear in the equatorial Indian Ocean,inducing the onset stage of the IOD.This study shows that the SSTA associated with the IOSD can lead to the onset of IOD with the aid of atmosphere circulation and also explains why some IOD events in the tropical tend to be followed by IOSD in the southern Indian Ocean.FENG Junqiao HU Dunxin YU Lejiang 2014Acta Oceanologica Sinica2014,33,1:3
3Review on observational studies of western tropical Pacific Ocean circulation and climate显示文摘The Western Tropical Pacific(WTP) Ocean holds the largest area of warm water(>28℃) in the world ocean referred to as the Western Pacific Warm Pool(WPWP),which modulates the regional and global climate through strong atmospheric convection and its variability.The WTP is unique in terms of its complex 3-D ocean circulation system and intensive multiscale variability,making it crucial in the water and energy cycle of the global ocean.Great advances have been made in understanding the complexity of the WTP ocean circulation and associated climate impact by the international scientific community since the 1960 s through field experiments.In this study,we review the evolving insight to the 3-D structure and multi-scale variability of the ocean circulation in the WTP and their climatic impacts based on in-situ ocean observations in the past decades,with emphasis on the achievements since 2000.The challenges and open que stions remaining are reviewed as well as future plan for international study of the WTP ocean circulation and climate.HU Dunxin WANG Fan SPRINTALL Janet WU Lixin RISER Stephen CRAVATTE Sophie GORDON Arnold ZHANG Linlin CHEN Dake ZHOU Hui ANDO Kentaro WANG Jianing LEE Jae-Hak HU Shijian WANG Jing ZHANG Dongxiao FENG Junqiao LIU Lingling VILLANOY Cesar KALUWIN Chalapan QU Tangdong MA Yixin 2020Journal of Oceanology and Limnology2020,38,4:3
4Dynamic features of near-inertial oscillations in the Northwestern Pacific derived from mooring observations from^2015 to 2018显示文摘Near-inertial oscillation is an important physical process transferring surface wind energy into deep ocean.We investigated the near-inertial kinetic energy(NIKE)variability using acoustic Doppler current profiler measurements from a mooring array deployed in the tropical western Pacific Ocean along 130°E at 8.5°N,11°N,12.6°N,15°N,and 17.5°N from September 2015 to January 2018.Spatial features,decay timescales,and significant seasonal variability of the observed NIKE were described.At the mooring sites of 17.5°N,15°N,and 12.6°N,the NIKE peaks occurred in boreal autumn and the NIKE troughs were observed in boreal spring.By contrast,the NIKE at 11°N and 8.5°N showed peaks in winter and troughs in summer.Tropical cyclones and strong wind events played an important role in the emergence of high-NIKE events and explained the seasonality and latitudinal characteristics of the observed NIKE.HU Shijian LIU Lingling GUAN Cong ZHANG Linlin WANG Jianing WANG Qingye MA Jie WANG Fujun JIA Fan FENG Junqiao LU Xi WANG Fan HU Dunxin 2020Journal of Oceanology and Limnology2020,38,4:2

7Coherence preservation during light-surface plasmon polaritons-light transformation显示文摘We constructed a four-layer system composed of a prism,a silver film,an air layer and a lithium niobate crystal.Initially we used two coherent light beams to excite surface plasmons.The surface plasmons were then decoupled into light in the photorefractive crystal where a holographic grating was recorded.The two beams remained coherent through light to surface plasmons to light transformation.Studying the characteristics of the holographic grating we found out that the thickness of the grating was to the order of hundreds of microns.The thick holographic grating suggests that the holographic recording in the photorefractive materials was induced by the leaky waves rather than by surface plasmon polaritons directly.TAN XinHui WANG JunQiao CAI Wei MENG Tao XIANG YinXiao LI Wei ZHANG XinZheng 2013Science China(Physics,Mechanics & Astronomy)2013,56,9:1

11Reservoir controlling differences between consequent faults and antithetic faults in slope area outside of source: A case study of the south-central Wenan slope of Jizhong Depression, Bohai Bay Basin, East China显示文摘The control effects of different occurrence faults on oil and gas accumulation and distribution in the outer slope area of oil and gas reservoirs were studied taking the south-central Wen’an slope of the Jizhong depression in the Bohai Bay Basin as an example.Based on 3D seismic data and the distribution of oil and water,the controlling differences between consequent fault and antithetic fault were analyzed and compared from the formation and evolution rule of faults and the formation mechanism of fault traps,including development positions of the consequent fault traps and antithetic fault traps,oil and gas distribution horizon adjusted by fault and formation period of fault traps.The differences between consequent faults and antithetic faults in controlling reservoirs have three main aspects:(1)Consequent fault traps and antithetic fault traps are in different positions,the consequent fault traps are at the segmented growing point in the hanging wall of'hard-linkage'faults,while the antithetic fault traps are developed in the position with the largest throw in the footwall because of tilting action;(2)The two kinds of faults result in different oil and gas distribution vertically,oil and gas adjusted by consequent faults is distributed in a single layer or multi-layers,while oil and gas adjusted by antithetic faults occur in single layers;(3)The two kinds of fault traps are formed in different periods,the consequent fault traps are formed at the time when the related faults enter the stage of'hard-linkage',while the antithetic fault traps are formed at the beginning of the fault active period.LIU Junqiao WANG Haixue LYU Yanfang SUN Tongwen ZHANG Mengdi HE Wei SUN Yonghe ZHANG Tong WANG Chao CAO Lanzhu 2018Petroleum Exploration and Development2018,45,1:1

16A molecular framework for signaling crosstalk between jasmonate and ethylene in anthocyanin biosynthesis,trichome development,and defenses against insect herbivores in Arabidopsis显示文摘The phytohormones ethylene(ET)and jasmonate(JA)regulate plant development,growth,and defense responses;however,the molecular basis for their signaling crosstalk is unclear.Here,we show that JA-ZIM-domain(JAZ)proteins,which repress JA signaling,repress trichome initiation/branching and anthocyanin accumulation,and inhibit the transcriptional activity of the basic helix-loop-helix(bHLH)-MYBmembers(GLABRA3(GL3)-GL1 and TRANSPARENT TESTA 8(TT8)-MYB75)of WD-repeat/bHLH/MYB(WBM)complexes.The ET-stabilized transcription factors ETHYLENEINSENSITIVE3(EIN3)and EIN3-LIKE1(EIL1)were found to bind to several members of WBM complexes,including GL3,ENHANCER OF GLABRA3(EGL3),TT8,GL1,MYB75,and TRANSPARENT TESTA GLABRA1(TTG1).This binding repressed the transcriptional activity of the b HLH-MYB proteins and inhibited anthocyanin accumulation,trichome formation,and defenses against insect herbivores while promoting root hair formation.Conversely,the JA-activated b HLH members GL3,EGL3,and TT8 of WBM complexes were able to interact with and attenuate the transcriptional activity of EIN3/EIL1 at the HOOKLESS1 promoter,and their overexpression inhibited apical hook formation.Thus,this study demonstrates a molecular framework for signaling crosstalk between JA and ET in plant development,secondary metabolism,and defense responses.Susheng Song Bei Liu Junqiao Song Shihai Pang Tianxue Song Shang Gao Yue Zhang Huang Huang Tiancong Qi 2022Journal of Integrative Plant Biology2022,64,9:1
