1Distribution, features, and influence factors of the submarine topographic boundaries of the Okinawa Trough显示文摘Based on multiple types of data, the topographical features of the Okinawa Trough(OT) have been characterized and a computation method has been proposed to determine the break point of continental shelf(BOS), foot point of the continental slope(FOS), the central axial point, and the maximum depth point. A total of 48 topographical profiles that crosscut the continental slope have been used to determine the trends of the BOS and FOS(the BOS and FOS lines) in the East China Sea(ECS). The trend of central axial points in the OT has been similarly determined by analyzing 39 topographical profiles across the axis of the trough. The BOS line forms the boundary between the continental shelf and slope. In the ECS, the BOS line roughly follows the 200 m isobath, continuously in the northern and middle parts of the OT, but jumping about somewhat in the south. The FOS line is the boundary between the continental slope and the bottom of the trough. The depth of the FOS increases gradually from north to south in the OT. Intense incisions by canyons into the slope in the southern part of the trough have led to the complex distribution of FOS. Topographical profiles crosscutting the northern, middle, and southern parts of the OT exhibit features that include: a single W-shape, a composite W-shape, and a U-shape, respectively, which suggests that in the middle and northern parts of the trough the central axial points are always located on seamount peaks or ridges associated with linear seamounts, whereas in the south they are found in the center of en echelon depressions. The line formed by the central axial points is the east-west dividing line of the OT, which indicates that the trough is a natural gap that prevents the extension of ECS continental shelf to the east. The distributions of the BOS and FOS lines are influenced by fluctuation of sea levels and submarine canyons, whereas the distribution of axis lines is controlled by tectonics and deposition.WU ZiYin LI JiaBiao JIN XiangLong SHANG JiHong LI ShouJun JIN XiaoBing 2014Science China Earth Sciences2014,57,8:11
2Adsorptive property of Cu^(2+)-loaded montmorillonite clays for Escherichia coli K_(88) in vitro显示文摘The adsorption properties of Cu 2+ -loaded montmorillonite clays (MMT-Cu) for Escherichia coli K 88 as a function of time,bacteria concentrations,pH,ionic strength and temperature were investigated.The results showed that the bacteria adsorption onto MMT-Cu surface reached equilibrium after 90 min.The percentages of E.coli K 88 adsorbed onto the surfaces of MMT-Cu and montmorillonite clays (MMT) at equilibrium were 88.9% and 56.5%,respectively.Scanning electron microscopy revealed that a lot of E.coli K 88 adhered to the surface of MMT-Cu.The zeta potential of MMT-Cu was relatively high as compared to that of MMT.The adsorptive ability of MMT-Cu for E.coli K 88 was higher than that of MMT (P < 0.05).Moreover,pH,ionic strength and temperature produced a strong influence on the extent of E.coli K 88 adsorption to surface of MMT-Cu and MMT.The mechanism of adsorption of E.coli onto MMT-Cu may involve electrostatic attraction and physiochemical properties of bacterial cell walls and minerals surfaces.Tong Guo Shoujun Cao Rui Su Zhiqiang Li Ping Hu Zirong Xu 2011Journal of Environmental Sciences2011,23,11:7
3The morphotectonics and its evolutionary dynamics of the central Southwest Indian Ridge (49° to 51°E)显示文摘The morphotectonic features and their evolution of the central Southwest Indian Ridge(SWIR)are discussed on the base of the high-resolution full-coverage bathymetric data on the ridge between 49°–51°E.A comparative analysis of the topographic features of the axial and flank area indicates that the axial topography is alternated by the ridge and trough with en echelon pattern and evolved under a spatial-temporal migration especially in 49°–50.17°E.It is probably due to the undulation at the top of the mantle asthenosphere,which is propagating with the mantle flow.From 50.17°to 50.7°E,is a topographical high terrain with a crust much thicker than the global average of the oceanic crust thickness.Its origin should be independent of the spreading mechanism of ultra-slow spreading ridges.The large numbers of volcanoes in this area indicate robust magmatic activity and may be related to the Crozet hot spot according to RMBA(residual mantle Bouguer anomaly).The different geomorphological feature between the north and south flanks of the ridge indicates an asymmetric spreading,and leading to the development of the OCC(oceanic core complex).The tectonic activity of the south frank is stronger than the north and is favorable to develop the OCC.The first found active hydrothermal vent in the SWIR at 37°47′S,49°39′E is thought to be associated with the detachment fault related to the OCC.LIANG Yuyang LI Jiabiao LI Shoujun RUAN Aiguo NI Jianyu YU Zhiteng ZHU Lei 2013Acta Oceanologica Sinica2013,32,12:7
4Classification of seamount morphology and its evaluating significance of ferromanganese crust in the central Pacific Ocean显示文摘Using the SeaBeam technology, the morphology of seamount and its relation to the formation of cobalt-rich crust in the central Pacific Ocean were surveyed during the cruise in 2003 for marine mineral resources. The result shows that seamounts can be divided morphologically into the spire seamount and the flat topped seamount. These two types of seamount bear great differences in their landform, lithology and cobalt-rich crust. On the upper portion of the flat topped seamount, the flat top and the sharp escarpments are unfavorable to the growth of crust, and, consequently, the crusts here are mostly laminar or gravelly, their thicknesses generally show great variations, and the consecutive ore body often develops in its deep water region. On the spire topped seamount, however, the flat area is small, and its gradient is constant without large variation from the top to the bottom. This favors the growth of cobalt-rich crust and often leads to consecutive tabular ore body of medium thickness, occurring on the spire topped seamount from the shallow water region to the deep water region. The cobalt-rich crust on the spire topped seamount is much better than that on the flat topped seamount for the crust abundance, crust coverage and number of ore-occurrences within unit area. Furthermore, the crust on the spire topped seamount is rich in cobalt, nickel, manganese elements of high economic value. Because the crust with high quality ore often occurs in the shallow water region on the spire topped seamount, it can be mined and use more easily in the future.CHU Fengyou SUN Guosheng MA Weilin LI Shoujun QIAN Xinyan ZHAO Hongqiao 2006Acta Oceanologica Sinica2006,25,2:6
5He–Ar Isotopic Tracing of Pyrite from Ore-forming Fluids of the Sanshandao Au Deposit, Jiaodong Area显示文摘The Sanshandao Au deposit is located in the famous Sanshandao metallogenic belt,Jiaodong area.To date,accumulative Au resources of 1000 t have been identified from the belt.Sanshandao is a world-class gold deposit with Au mineralization hosted in Early Cretaceous Guojialing-type granites.Thus,studies on the genesis and ore-forming element sources of the Sanshandao Au deposit are crucial.He and Ar isotopic analyses of fluid inclusions from pyrite(the carrier of Au)indicate that the fluid inclusions have 3 He/4 He=0.043–0.21 Ra with an average of 0.096 Ra and 40 Ar/36 Ar=488–664 with an average of 570.8.These values represent the initial He and Ar isotopic compositions of ore-forming fluids for trapped fluid inclusions.The comparison of H–O isotopic characteristics combined with deposit geology and wall rock alteration reveals that the ore-forming fluids of the Sanshandao Au deposit show mixed crust–mantle origin characteristics,and they mainly comprise crust-derived fluid mixed with minor mantle-derived fluid and meteoric water during the uprising process.The ore-forming elements were generally sourced from pre-Cambrian meta-basement rocks formed by Mesozoic reactivation and mixed with minor shallow crustal and mantle components.HAN Zhenyu YU Xiaowei LI Shoujun Tian Jingxiang WANG Zhongliang YU Xiaojing WANG Ligong 2019Acta Geologica Sinica(English Edition)2019,93,6:5

7Blue revolution for food security under carbon neutrality: A case from the water-saving and drought-resistance rice显示文摘The increasing concentration of greenhouse gases(GHGs)in Earth's atmosphere leads to global warming,which further causes a series of climate changes and does great harm to both human society and natural ecosystems.Agricultural GHG emissions,mainly in theform of methane(CH4)and nitrous oxide(N2O),areasignificantsourceofGHGs,accountingfor~14%total global GHGs(Zhang et al.,2022).One major source of agricultural GHGs is CH4 emissions from rice paddies,which is responsiblefor~10%-12%ofhuman-inducedCH4emissions(van Groenigen et al.,2013)and contributes~2.40%to the enhanced global warming effect(Zhang et al.,2022).The global warming potential of GHGs emissions from rice systems is roughly four times higher than either wheat or maize(Linquist et al.,2012).Hui Xia Xianxian Zhang Yi Liu Junguo Bi Xiaosong Ma Anning Zhang Hongyan Liu Liang Chen Sheng Zhou Huan Gao Kai Xu Haibin Wei Guolan Liu Feiming Wang Hongyang Zhao Xingxing Luo Danping Hou Qiaojun Lou Fangjun Feng Liguo Zhou Shoujun Chen Ming Yan Tianfei Li Mingshou Li LeiWang Zaochang Liu Xinqiao Yu HanweiMei Lijun Luo 2022Molecular Plant2022,15,9:3
8Nonvolatile reconfigurable dynamic Janus metasurfaces in the terahertz regime显示文摘Metasurfaces,especially tunable ones,have played a major role in controlling the amplitude,phase,and polarization of electromagnetic waves and attracted growing interest,with a view toward a new generation of miniaturized devices.However,to date,most existing reconfigurable devices are bounded in volatile nature with sustained external energy to maintain and single functionality,which restrict their further applications.Here,we demonstrate for the first time,to our knowledge,nonvolatile,reconfigurable,and dynamic Janus metasurfaces by incorporating phase-change material Ge_(2)Se_(2)Te_(5)(GST)in the terahertz(THz)regime.First,we experimentally show the reversible switching characteristic of GST on large areas by applying a single nanosecond laser pulse,which exhibits excellent contrast of THz properties in both states.Then,we present a multiplex metasurface scheme.In each metasurface,three sets of structures are adopted,in which two sets integrate GST.The effective structures can be reversely modulated by the amorphization and crystallization of GST.As a proof of concept,the dynamic beam splitter,bifocal metalens,dual-mode focusing optical vortex generators,and switchable metalens/focusing optical vortex generators are designed,fabricated,and experimentally characterized,and can be switched reversibly and repeatedly with the help of optical and thermal stimuli.Our scheme will pave the way toward the development of multifunctional and compact THz devices and may find use for applications in THz imaging,sensing,and communications.SHOUJUN ZHANG XIEYU CHEN KUAN LIU HAIYANG LI YUEHONG XU XIAOHAN JIANG YIHAN XU QINGWEI WANG TUN CAO ZHEN TIAN 2022Photonics Research2022,10,7:2
9Resources calculation of cobalt-rich crusts with the grid subdivision and integral method显示文摘On the basis of three geological models and several orebody boundaries,a method of grid subdivision and integral has been proposed to calculate and evaluate the resources of cobalt-rich crusts on the seamounts in the central Pacific Ocean.The formulas of this method are deduced and the interface of program module is designed.The method is carried out in the software 'Auto mapping system of submarine topography and geomorphology MBChart'.This method and program will possibly become a potential tool to calculate the resources of seamounts and determine the target diggings for China's next Five-year Plan.WU Ziyin CHU Fengyou MA Weilin LI Shoujun SHANG Jlhong 2007Acta Oceanologica Sinica2007,26,5:2

12Development and application of perfect SSR markers in cotton显示文摘Background:This study aimed to develop a set of perfect simple sequence repeat(SSR)markers with a single copy in the cotton genome,to construct a DNA fingerprint database suitable for authentication of cotton cultivars.We optimized the polymerase chain reaction(PCR)system for multi-platform compatibility and improving detection efficiency.Based on the reference genome of upland cotton and 10×resequencing data of 48 basic cotton germplasm lines,single-copy polymorphic SSR sites were identified and developed as diploidization SSR markers.The SSR markers were detected by denaturing polyacrylamide gel electrophoresis(PAGE)for initial screening,then fluorescence capillary electrophoresis for secondary screening.The final perfect SSR markers were evaluated and verified using 210 lines from different sources among Chinese cotton regional trials.Results:Using bioinformatics techniques,1246 SSR markers were designed from 26626 single-copy SSR loci.Adopting a stepwise(primary and secondary)screening strategy,a set of 60 perfect SSR markers was selected with high amplification efficiency and stability,easy interpretation of peak type,multiple allelic variations,high polymorphism information content(PIC)value,uniform chromosome distribution,and single-copy characteristics.A multiplex PCR system was established with ten SSR markers using capillary electrophoresis detection.Conclusions:A set of perfect SSR markers of cotton was developed and a high-throughput SSR marker detection system was established.This study lays a foundation for large-scale and standardized construction of a cotton DNA fingerprint database for authentication of cotton varieties.WU Yuzhen HUANG Longyu ZHOU Dayun FU Xiaoqiong LI Chao WEI Shoujun PENG Jun KUANG Meng 2020Journal of Cotton Research2020,3,3:2

14Reconfigurable and nonvolatile terahertz lithography-free photonic devices based on phase change films显示文摘High-performance terahertz(THz)devices with reconfigurable features are highly desirable in many promising THz applications.However,most of the existing reconfigurable THz elements are still limited to volatile responses,single functionality,and time-consuming multistep manufacturing procedures.In this paper,we report a lithography-free approach to create reconfigurable and nonvolatile THz components by exploring the reversible,nonvolatile,and continuous THz modulation capability of the phase change material Ge_(2)Sb_(2)Te_(5).As a proof of concept,THz gratings with significant Rayleigh anomalies and diffraction as well as ultrathin THz flat lenses with subwavelength and ultra-broadband focusing capabilities are designed and fabricated on ultrathin Ge_(2)Sb_(2)Te_(5)films using the presented photo-imprint strategy.Moreover,such a method can also be adopted to create more complex THz devices,such as Pancharatnam–Berry phase metasurfaces and grayscale holographic plates.With these findings,the proposed method will provide a promising solution to realize reconfigurable and nonvolatile THz elements.XIEYU CHEN SHOUJUN ZHANG KUAN LIU YUEHONG XU XIAOHAN JIANG HAIYANG LI XI FENG QINGWEI WANG YONGCHANG LU KEMENG WANG TUN CAO ZHEN TIAN 2023Photonics Research2023,11,4:1
