| 1 | Zircon U-Pb SHRIMP ages of the Taiping (calc-alkaline)-Huangshan (alkaline) composite intrusion:Constraints on Mesozoic lithospheric thinning of the southeastern Yangtze Craton,China显示文摘The Taiping-Huangshan composite intrusion is a unique complex with characteristics changing from calc-alkaline (Taiping intrusion) to alkaline (Huangshan intrusion). Huangshan intrusion samples show a spectacular tetrad effect in their REE distribution patterns as well as non-CHARAC (charge-and radius-controlled) trace element behavior, indicating a highly evolved late-stage magma component. This composite intrusion provides a rare opportunity to investigate the variance of tectonic setting and lithospheric thinning of the southeastern Yangtze Craton in late Mesozoic era. Zircon SHRIMP U-Pb analyses yield an emplacement age of 140.6±1.2 Ma for the Taiping intrusion, and ages of 127.7±1.3, 125.7±1.4, 125.1±1.5, and 125.2±5.5 Ma for four samples from the Huangshan intrusion respectively. The ages for four different phases of the Huangshan intrusion agree within their small analytical errors, indicating that the emplacement was in a short time. The Taiping and Huangshan intrusions are intimately associated, but there is about 15 Ma interval between their intrusion, and the magma characters change from calc-alkaline to alkaline without transition. This probably corresponds to lithospheric thinning of the southeastern Yangtze Craton. This event possibly happened from about 141 Ma (the emplacement age of the Taiping intrusion), to 128 Ma (start of emplacement of the Huangshan intrusion). The thinning mechanism is dominantly delamination. | XUE HuaiMin WANG YingGeng MA Fang WANG Cheng WAN DeEn ZUO YanLong | 2009 | Science China Earth Sciences2009,52,11: | 28 |
| 2 | Effect of Reclamation Time and Land Use on Soil Properties in Changjiang River Estuary,China显示文摘The objective of this study is to analyze soil physical and chemical properties,soil comprehensive functions and impact factors after different years of reclamation.Based on the survey data taken from 216 soil sampling points in the Fengxian Reclamation Area of the Changjiang (Yangtze) River Estuary,China in April 2009 and remotely sensed TM data in 2006,while by virtue of multivariate analysis of variance (MANOVA),geo-statistical analysis (GA),prin-cipal component analysis (PCA) and canonical correspondence analysis (CCA),it was concluded that:1) With the in-crease in reclamation time,soil moisture,soil salinity,soil electric conductivity and soil particle size tended to decline,yet soil organic matter tended to increase.Soil available phosphorous tended to increase in the early reclamation period,yet it tended to decline after about 49 years of reclamation.Soil nitrate nitrogen,soil ammonia nitrogen and pH changed slightly in different reclamation years.Soil physical and chemical properties reached a steady state after about 30 years of reclamation.2) According to the results of PCA analysis,the weighted value (0.97 in total) that represents soil nutrient factors (soil nitrate nitrogen,soil organic matter,soil available phosphorous,soil ammonia nitrogen,pH and soil particle size) were higher than the weighted value (0.48 in total) of soil limiting factors (soil salinity,soil elec-tric conductivity and soil moisture).The higher the F value is,the better the soil quality is.3) Different land use types play different roles in the soil function maturity process,with farmlands providing the best contribution.4) Soil physi-cal and chemical properties in the reclamation area were mainly influenced by reclamation time,and then by land use types.The correlation (0.1905) of the composite index of soil function (F) with reclamation time was greater than that with land use types (-0.1161). | SUN Yongguang LI Xiuzhen ülo MANDER HE Yanlong JIA Yue MA Zhigang GUO Wenyong XIN Zaijun | 2011 | Chinese Geographical Science2011,21,4: | 17 |
| 3 | Seasonal dynamics of water bloom-forming Microcystis morphospecies and the associated extracellular microcystin concentrations in large,shallow,eutrophic Dianchi Lake显示文摘The increasing occurrence of Microcystis blooms is of great concern to public health and ecosystem due to the potential hepatotoxic microcystins(MCs)produced by these colonial cyanobacteria.In order to interpret the relationships between variations of Microcystis morphospecies and extracellular MC concentrations,the seasonal dynamics of phytoplankton community composition,MC concentrations,and environmental parameters were monitored monthly from August,2009 to July,2010.The results indicated that Microcystis dominated total phytoplankton abundance from May to December(96%–99%of total biovolume),with toxic Microcystis viridis and non-toxic Microcystis wesenbergii dominating after July(constituting 65%–95%of the Microcystis population),followed by M.viridis as the sole dominant species from November to January(49%–93%).Correlation analysis revealed that water temperature and nutrient were the most important variables accounting for the occurrence of M.wesenbergii,while the dominance of M.viridis was related with nitrite and nitrate.The relatively low content of MCs was explained by the association with a large proportion of M.viridis and M.wesenbergii,small colony size of Microcystis populations,and low water temperature,pH and dissolved oxygen.The extracellular MC(mean of 0.5±0.2μg/L)of water samples analyzed by enzyme-linked immunosorbent assay(ELISA)demonstrated the low concentrations of MC in Dianchi Lake which implied the low potential risk for human health in the basin.The survey provides the first whole lake study of the occurrence and seasonal variability of Microcystis population and extracellular MCs that are of particular interest for water quality monitoring and management. | Yanlong Wu Lin Li Nanqin Gan Lingling Zheng Haiyan Ma Kun Shan Jin Liu Bangding Xiao Lirong Song | 2014 | Journal of Environmental Sciences2014,26,9: | 12 |
| 4 | High-performance silicon−graphene hybrid plasmonic waveguide photodetectors beyond 1.55μm显示文摘Graphene has attracted much attention for the realization of high-speed photodetection for silicon photonics over a wide wavelength range.However,the reported fast graphene photodetectors mainly operate in the 1.55μm wavelength band.In this work,we propose and realize high-performance waveguide photodetectors based on bolometric/photoconductive effects by introducing an ultrathin wide silicon−graphene hybrid plasmonic waveguide,which enables efficient light absorption in graphene at 1.55μm and beyond.When operating at 2μm,the present photodetector has a responsivity of ~70 mA/W and a setup-limited 3 dB bandwidth of >20 GHz.When operating at 1.55μm,the present photodetector also works very well with a broad 3 dB bandwidth of >40 GHz(setup-limited)and a high responsivity of ~0.4 A/W even with a low bias voltage of−0.3 V.This work paves the way for achieving highresponsivity and high-speed silicon-graphene waveguide photodetection in the near/mid-infrared ranges,which has applications in optical communications,nonlinear photonics,and on-chip sensing. | Jingshu Guo Jiang Li Chaoyue Liu Yanlong Yin Wenhui Wang Zhenhua Ni Zhilei Fu Hui Yu Yang Xu Yaocheng Shi Yungui Ma Shiming Gao Limin Tong Daoxin Dai | 2020 | Light(Science & Applications)2020,9,1: | 10 |

| 7 | New Approaches and Markers for Identifying Secondary Biogenic Coalbed Gas显示文摘According to the adsorption-desorption characteristics of coalbed gas and analysis of various experimental data,this paper proposes that the generation of secondary biogenic gas(SBG) and its mixing of with the residual thermogenic gas at an early stage inevitably lead to secondary changes of the thermogenic gas and various geochemical additive effects.Experimental results also show that the fractionation of the carbon isotope of methane of coal core desorption gas changes very little;the δ13C1 value of the mixed gas of biogenic and thermogenic gases is between the δ13C1 values of the two 'original' gases,and the value is determined by the carbon isotopic compositions and mixing proportions of the two 'original' methanes.Therefore this paper proposes that the study on the secondary changes of the thermogenic gas and various additive effects is a new effective way to study and identify SBG.Herein,a systematic example of research on the coalbed gas(Huainan coalbed gas) is further conducted,revealing a series of secondary changes and additive effects,the main characteristics and markers of which are:(1) the contents of CO2 and heavy-hydrocarbons decrease significantly;(2) the content of CH4 increases and the gas becomes drier;(3) the δ13C and δD values of methane decrease significantly and tend to have biogenetic characteristics;and(4) the values of δ13C2 and δ13CCO2 grow higher.These isotopic values also change with the degradation degrees by microbes and mixing proportions of the two kinds of gases in different locations.There exists a negative correlation between the δ13C1 vs δ13CCO2 values.The △δ13CC2-C1 values obviously become higher.The distributions of the △δ13CCO2-C1 values are within certain limits and show regularity.There exist a positive correlation between the N2 versus Ar contents,and a negative correlation between the N2 versus CH4 contents,indicating the down forward infiltration of the surface water containing air.These are important markers of the generation and existence of SBG. | TAO Mingxin LI Jing LI Xiaobin MA Yuzhen LI Zhongping WANG Zuodong GAO Zhongliang ZHANG Xiaojun WANG Yanlong | 2012 | Acta Geologica Sinica(English Edition)2012,86,1: | 4 |
| 8 | A 2~n scaling scheme for signed RNS integers and its VLSI implementation显示文摘High effcient implementation of scaling in residue number system (RNS) is one of the critical issues for the applications of RNS in digital signal processing (DSP) systems. In this paper, an effcient scaling algorithm for signed integers in RNS is proposed firstly through introducing a correction constant in negative integers scaling procedure. Based on the proposed scaling algorithm, an effcient RNS 2n scaling implementation method is presented, in which Chinese remainder theorem (CRT) and a redundant modulus are used to perform the base extension to obtain the least significant n bits of RNS integers. With the redundant modulus, the RNS sign detection can be achieved by the parity detection. And then, an approach to update the residue digit of the redundant channel is also proposed. Meanwhile, this paper provides a method of computing the correction constant of the redundant channel in negative integers scaling. The analysis results indicate that the complexity of the proposed scaling algorithm grows linearly with the word-length of the RNS dynamic range without using Look-up Table (LUT). Furthermore, the proposed algorithm is employed for a specific moduli set 2n scaling. The synthesis results show that the critical path of the proposed algorithm is shortened by 12%, the area and power consumption performance is improved by about 35%, compared to the existing cascading 2n scaling method for very large scale integration (VLSI) implementation under the same restriction. Besides, the VLSI layout indicates that the parallel structure is simpler. | MA Shang HU JianHao YE YanLong ZHANG Lin LING Xiang | 2010 | Science China(Information Sciences)2010,53,1: | 3 |

| 10 | High-temperature mechanical properties of as-extruded AZ80 magnesium alloy at different strain rates显示文摘The mechanical properties of as-extruded AZ80 magnesium alloy at temperatures of 450-525℃ and strain rates of 3.0 s^(−1)and 0.15 s^(−1)were investigated by tensile tests.Zero ductility of alloy appeared at 500℃ with a strain rate of 0.15 s^(−1),while the zero strength and zero ductility of the alloy were obtained nearly simultaneously at 525℃ with a strain rate of 3.0 s^(−1).The results indicated that the lower strain rate accelerated the arrival of zero ductility.As the temperature increased,the failure mode of the alloy developed from trans-granular fracture to cleavage fracture and then to inter-granular fracture with the feature of sugar-like grains and fusion traces.The existence of the low-melting composite ofβ-Mg_(17)Al_(12) and Al_(8)Mn_(5) particles segregated near the Mg_(17)Al_(12) phase along grain boundaries were demonstrated to be the reason for the brittle fracturing of the AZ80 alloy at high temperatures.Furthermore,microstructural evolution at temperatures approaching the solidus temperature was discussed to clarify magnesium alloy’s high temperature deformation mechanism. | Wenjun Liu Bin Jiang Hongchen Xiang Qing Ye Shengqi Xia Siqiang Chen Jiangfeng Song Yanlong Ma Mingbo Yang | 2022 | International Journal of Minerals,Metallurgy and Materials2022,29,7: | 3 |
| 11 | Rolling texture development in a dual-phase Mg-Li alloy:The role of temperature显示文摘Dual-phase Mg-Li alloys sheets were rolled at four different temperatures ranging from liquid nitrogen to 300℃to explore effect of rolling temperature on texture and mechanical properties of the material.Crystal plasticity simulation was utilized to illustrate the influence of slip activity on rolling texture development.The results show that the rolling texture is largely depended on deformation temperature.Unlike commercial Mg alloys,the critical resolved shear stress of basal slip inα-Mg phase of Mg-Li alloy decreased more significantly by increasing temperature compared to that of pyramidalslip.Enhancement of basal slip by increasing temperature triggered a decrease of split angle of basal poles for the double-peak texture.Prismaticslip largely enhanced by increasing temperature upon 200℃,which induced a wider orientation spread along the transverse direction.For theβ-Li phase,the promotion of{110}<111>slip system at elevated temperature triggered the enhancement of{211}<110>and{111}<211>texture components.The cryo-rolled sample exhibited the highest strength compared to the others due to a strong hardening behavior at this temperature.A two-stage hardening behavior was observed in these as-rolled dual-phase alloys.Strain transition at phase boundaries could be the reason for appearance of this two-stage hardening. | Xiaoyan Li Fei Guo Yanlong Ma Luyao Jiang Hongliang Lai Haiding Liu Dingfei Zhang Risheng Pei | 2023 | Journal of Magnesium and Alloys2023,11,8: | 2 |
| 12 | Impact Factors on Distribution and Characteristics of Natural Plant Community in Reclamation Zones of Changjiang River Estuary显示文摘To identify impact factors on the distribution and characters of natural plants community in reclamation area, with survey data from 67 plant quadrats in July 2009, soil properties data from 216 sampling points in April 2009, and TM (30 m) data in 2006, the composition and characteristics of natural plants community in different time of the Fengxian area in the Changjiang (Yangtze) River estuary were analyzed with two-way indicator species analysis (TWINSPAN), multivariate analysis of variance (MANOVA), detrended canonical correspondence analysis (DCCA) and canonical correspondence analysis (CCA). The results show that: 1) The plant communities in the reclaimed area are mainly mesophytes and helophytic-mesophytic transitional communities, showing a gradient distribution trend with the change in reclamation years. Species richness (MA), species diversity (H) and above-ground biomass also increase with the increase of reclamation years. Nevertheless, they appear to decline slightly in the middle and late reclamation period (> 30 years). 2) With the rise in land use levels, the changes in species richness and species diversity tend to increase at first and then decrease; species dominance (D), however, tends to decline; and above-ground biomass increases slightly. 3) The distribution of the plant community is mainly influenced by the following factors: land use levels (R = 0.55, p < 0.05), soil moisture (R = 0.53, p < 0.05), soil salinity (R = 0.43, p < 0.05) and reclamation time (R = 0.40, p < 0.05). | SUN Yongguang LI Xiuzhen HE Yanlong JIA Yue MA Zhigang GUO Wenyong XIN Zaijun | 2012 | Chinese Geographical Science2012,22,2: | 2 |
| 13 | pH-Responsive supramolecular DOX-dimer based on cucurbit[8]uril for selective drug release显示文摘A supramolecular dimer of doxorubicin(DOX)was constructed via ternary host-guest interactions between cucurbit[8]uril(CB[8])and tryptophan modified DOX(DOX-Trp,connected with an acid-labile bond)and we demonstrate for the first time that a supramolecular dimer of DOX can be formed upon homo-dimerization by CB[8],which may act as a stimuli pH-responsive,supramolecular DOX dimer prodrug system.This supramolecular DOX dimer transported DOX efficiently and selectively to cancer cells,thereby exhibiting significantly minimized cytotoxicity against noncancerous cells while maintaining effective cytotoxicity against cancer cells.Under this strategy,many other anticancer drugs could be chemically modified and loaded as a dimeric'ammunition'into CB[8]as supramolecular dimer prodrug systems(or a'jet fighter')for improved cancer therapy. | Qian Cheng Shengke Li Yanlong Ma Hang Yin Ruibing Wang | 2020 | Chinese Chemical Letters2020,31,5: | 2 |
