| 2 | Distribution,fluxes and decadal changes of nutrients in the Jiulong River Estuary,Southwest Taiwan Strait显示文摘The Jiulong River Estuary (JRE) is a typical subtropical macro-tide estuary on the southwest coast of the Taiwan Strait (TWS),which has been greatly impacted by human activities over the past 30 years.To understand nutrient dynamics and fluxes under such a heavy background of anthropogenic perturbation,eight cruises were conducted from April 2008 to April 2011,covering both wet (May to September) and dry (October to April next year) seasons.Nutrient concentrations were very high for the freshwater end-member in the upper reach of the JRE (nitrate (NO 3-N):120-230 mol L-1 ;nitrite (NO 2-N):5-15 mol L-1 ;ammonium (NH 4-N):15-170 mol L-1 ;soluble reactive phosphorus (SRP):1.2-3.5 mol L-1 ;dissolved silicate (DSi):200-340 mol L-1).In dry seasons,concentrations of these nutrients were higher than in wet seasons.Nitrate was the dominant chemical species of dissolved inorganic nitrogen (DIN),with percentages of 67%-96% in wet seasons and 55%-72% in dry seasons.Distributions of NO 3-N and DSi against salinity were nearly constant during all cruises,and showed generally conservative mixing behaviors in the estuary (1 | YAN XiuLi ZHAI WeiDong HONG HuaSheng LI Yan GUO WeiDong HUANG Xiao | 2012 | Chinese Science Bulletin2012，57，18： | 16 |
| 3 | Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，3： | 6 |
| 4 | Dynamic changes of phosphatidylinositol and phosphatidylinositol 4-phosphate levels modulate H^(+)-ATPase and Na^(+)/H^(+) antiporter activities to maintain ion homeostasis in Arabidopsis under salt stress显示文摘Plant metabolites are dynamically modified and distributed in response to environmental changes.How-ever,it is poorly understood how metabolic change functions in plant stress responses.Maintaining ion ho-meostasis under salt stress requires coordinated activation of two types of central regulators:plasma membrane(PM)H^(+)-ATPase and Na^(+)/H^(+) antiporter.In this study,we used a bioassay-guided isolation approach to identify endogenous small molecules that affect PM H^(+)-ATPase and Na^(+)/H^(+) antiporter activities and identified phosphatidylinositol(PI),which inhibits PM H^(+)-ATPase activity under non-stress conditions in Arabidopsis by directly binding to the C terminus of the PM H^(+)-ATPase AHA2.Under salt stress,the phosphatidylinositol 4-phosphate-to-phosphatidylinositol(PI4P-to-PI)ratio increased,and PI4P bound and activated the PM Na^(+)/H^(+) antiporter.PI prefers binding to the inactive form of PM H^(+)-ATPase,while PI4P tends to bind to the active form of the Na^(+)/H^(+) antiporter.Consistent with this,pis1 mutants,with reduced levels of PI,displayed increased PM H^(+)-ATPase activity and salt stress toler-ance,while the pi4kβ1 mutant,with reduced levels of PI4P,displayed reduced PM Na^(+)/H^(+) antiporter activity and salt stress tolerance.Collectively,our results reveal that the dynamic change between PI and PI4P in response to salt stress in Arabidopsis is crucial for maintaining ion homeostasis to protect plants from un-favorable environmental conditions. | Yongqing Yang Xiuli Han Liang Ma Yujiao Wu Xiao Liu Haiqi Fu Guoyong Liu Xiaoguang Lei Yan Guo | 2021 | Molecular Plant2021，14，12： | 4 |
| 5 | xperimental investigation on cumulative propagation of thin film buckling under cyclic load显示文摘As instrument technology is needed for rapid determination of the smaller,thinner and lighter specimens,more stringent demands are related to thin films such as micro-electro-mechanical systems(MEMS),dielectric coatings and electronic packaging.Therefore,the requirement for testing platforms for rapidly determine the mechanical properties of thin films is increasing.Buckling of a film/substrate system could offer a variety of applications,ranging from stretchable electronics to micro-nanoscale metrology.In this paper,a fatigue-loading device has been designed to make the cyclic loading available for investigating the cumulative propagation of thin film buckling.The straight side buckling of thin compressed titanium film with the thickness of 50 nm deposited on organic glass substrates is investigated by using an optical microscope.The cumulative buckling propagation under the cyclic loading of a sequence of peak compression with the frequency 1 Hz is recorded by CCD camera.The buckling extension lengths are calculated by digital image measurement technology. | WANG ShiBin JIA HaiKun LI LinAn SUN Heng CUI DiQiang GUO ZhenShan XUE XiuLi | 2011 | Science China(Technological Sciences)2011，54，6： | 4 |
| 6 | Significant Inhibition of Porcine Epidemic Diarrhea Virus In Vitro by Remdesivir,Its Parent Nucleoside and β-D-N^(4)-hydroxycytidine显示文摘Porcine epidemic diarrhea(PED)caused by porcine epidemic diarrhea virus(PEDV)is widespread in the world.In recent years,the increased virulence of the virus due to viral variations,has caused great economic losses to the pig industry in many countries.It is always worthy to find effective therapeutic methods for PED.As an important class of antivirals,nucleoside drugs which target viral polymerases have been applied in treating human viral infections for half a century.Herein,we evaluated the anti-PEDV potential of three broad-spectrum antiviral nucleoside analogs,remdesivir(RDV),its parent nucleoside(RDV-N)andβ-D-N^(4)-hydroxycytidine(NHC).Among them,RDV-N was the most active agent in Vero E6 cells with EC_(50) of 0.31μmol/L,and more potent than RDV(EC_(50)=0.74μmol/L)and NHC(EC_(50)=1.17μmol/L).The activity of RDV-N was further confirmed using an indirect immuno-fluorescence assay.Moreover,RDV-N exhibited a good safety profile in cells and in mice.The high sequence similarity of the polymerase functional domains of PEDV with other five porcine coronaviruses indicated a broader antiviral spectrum for the three compounds.Generally,RDV-N is a promising broad-spectrum antiviral nucleoside,and it would be worthy to make some structural modifications to increse its oral bioavailability. | Yuanchao Xie Xiaozhen Guo Tianwen Hu Daibao Wei Xiuli Ma Jiaqiang Wu Bing Huang Jingshan Shen | 2021 | Virologica Sinica2021，36，5： | 3 |
| 7 | Influence of CaO and HZSM-5 on oxygen migration in Chlorella vulgaris polysaccharide pyrolysis显示文摘With polysaccharides of Chlorella pyrenoidosa as the raw material,the effects of CaO and HZSM-5 on the yield of bio-oil and the oxygen content in each phase in the pyrolysis of Chlorella vulgaris polysaccharides(CVP),which occurred in a tube furnace at 600℃,were comprehensively investigated.The reaction path of deoxidation was also analyzed by TG,GC and GC-MS.The GC-MS analysis of liquids showed that liquids from the pyrolysis of chlorella polysaccharides included a range of light oxygenated compounds(e.g.,furans,ketones and phenols),and the oxygen content of furan compounds decreased significantly with CaO and HZSM-5.Compared with the direct pyrolysis of polysaccharides(CVP),the catalytic pyrolysis contributed to the decrease in the oxygen content of organic components by 7.32%and 5.76%.The GC analysis showed that there was a remarkable downtrend in the release of oxygen-containing gas(CO and CO_(2)),and the emission of CO_(2) decreased from 53.11%to 32.92%.The results of the thermogravimetric analysis indicated that the reaction paths of deoxidation in the pyrolysis process of polysaccharides(CVP)with CaO and HZSM-5 varied from those of the direct pyrolysis process:the catalytic pyrolysis with HZSM-5 promoted the conversion of carbohydrate from furans to aromatics over strong acid sites,which was consistent with previous studies;CaO not only acted as a catalyst but also participated in the reaction to change the reaction paths.All results and findings can help to further understand the thermochemical utilization of CPP for bio-oil. | Xiuli Zhang Chunhu Li Anhong Tian Qingjie Guo Kelei Huang | 2019 | Carbon Resources Conversion2019，2，2： | 3 |
| 8 | Friction and Wear Properties of TiAl and Ti_2AlN/TiAl Composites at High Temperature显示文摘The high-temperature friction and wear properties of TiAl alloys and Ti2 AlN/TiAl composites(TTC) in contact with nickel-based superalloy were studied.The results showed that,at 800 and 1 000 ℃,the coefficient of the friction(COF) decreased with the increase of sliding velocity and the wear loss of the TTC decreased with the increase of volume fraction of Ti2 AlN.The wear mechanisms of the pairs are adhesive wear and the wear debris mainly comes from the contacting nickel-based superalloy.The intergranular fracture and the cracking of the phase boundary in the lamellar structure are the wear mode of TiAl alloy.The wear mode of TTC is phase boundary fracture and adhesive spalling.The abrasive resistance of TTC is slightly higher than that of TiAl alloy. | 孙东立 SUN Tao WANG Qing HAN Xiuli GUO Linlin | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，5： | 3 |
| 9 | Experimental and mechanistic study on chemical looping combustion of caking coal显示文摘Under high-temperature batch fluidized bed conditions and by employing juye coal as the raw material,the present study determined the effects of the bed material,temperature,OC/C ratio,steam flow and oxygen carrier cycle on the chemical looping combustion of coal.In addition,the variations taking place in the surface functional groups of coal under different reaction times were investigated,and the variations achieved by the gas released under the pyrolysis and combustion of Juye coal were analyzed.As revealed from the results,the carbon conversion ratio and rate were elevated significantly,and the volume fraction of the outlet CO_(2)remained more than 92%under the oxygen carriers.The optimized reaction conditions to achieve the chemical looping combustion of Juye coal consisted of a temperature of 900℃,an OC/C ratio of 2,as well as a steam flow rate of 0.5 g·min^(-1).When the coal was undergoing the chemical looping combustion,volatiles primarily originated from the pyrolysis of aliphatic-CH_(3)and-CH_(2),and CO and H_(2)were largely generated from the gasification of aromatic carbon.In the CLC process,H_(2)O and CO_(2)began to separate out at 270℃,CH4 and tar began to precipitate at 370℃,and the amount of CO_(2)was continuously elevated with the rise of the temperature. | Xiuli Zhang Zhengdong Gao Yongzhuo Liu Yuanhao Hou Xiaoqing Sun Qingjie Guo | 2021 | Chinese Journal of Chemical Engineering2021，34，9： | 2 |
| 10 | Directional preparation of naphthalene oil-rich tar from Beisu low-rank coal by low-temperature catalytic pyrolysis显示文摘Low-rank coal(LRC)can be converted to high value-added naphthalene and its alkylated derivatives through low-temperature catalytic pyrolysis.In this paper,the catalytic pyrolysis of Beisu LRC in a fixed-bed at low temperature was investigated.And the catalytic effects of HZSM-5,low-temperature carbocoal(LtC),and LtC-HZSM-5 on the content and yield of naphthalene oil were examined.The results showed that the generation of naphthalene oil in low-temperature LRC pyrolysis(LT-LP)process could be improved when LtC(prepared at 550℃)or HZSM-5 was individually used as a catalyst.Compared with sole pyrolysis of raw LRC,the addition of the LtC-HZSM-5 catalyst increased the content of naphthalene oil from 11.19 wt.%to 31.49 wt%.And the yield of naphthalene oil was increased from 1.07 wt%to 5.31 wt%.The reactions of micromolecular hydrogen-containing radicals(⋅MHCR)were optimized by LtC.⋅MHCR could be captured in relatively low-temperature region(200-400℃)and released at high temperature by LtC.The generation of phenolics was inhibited by HZSM-5.As a result,the naphthalene oil-rich tar was obtained through low-temperature LtC-HZSM-5 catalytic pyrolysis of Beisu LRC. | Tao Liu Xiuli Zhang Yongzhuo Liu Lingyun Wang Qingjie Guo | 2020 | Carbon Resources Conversion2020，3，1： | 2 |
| 11 | Defect-engineered Mn_(3)O_(4)/CNTs composites enhancing reaction kinetics for zinc-ions storage performance显示文摘The designing of reasonable nanocomposite materials and proper introduction of defect engineering are of great significance for the improvement of the poor electronic conductivity and slow reaction kinetics of manganese-based compounds. Herein, we report manganese-deficient Mn_(3)O_(4) nanoparticles which grow in-situ on highly conductive carbon nanotubes(CNTs)(denoted as DMOC) as an advanced cathode material for aqueous rechargeable zinc-ion batteries(RAZIBs). According to experimental and calculation results, the DMOC cathode integrates the advantages of enriched Mn defects and small particle size. These features not only enhance electronic conductivity but also create more active site and contribute to fast reaction kinetics. Moreover, the structure of DMOC is maintained during the charging and discharging process, thus benefiting for excellent cycle stability. As a result, the DMOC electrode delivers a high specific capacity of 420.6 m A h g^(-1) at 0.1 A g^(-1) and an excellent cycle life of 2800 cycles at 2.0 A g^(-1) with a high-capacity retention of 84.1%. In addition, the soft-packaged battery assembled with DMOC cathode exhibits long cycle life and high energy density of 146.3 Wh kg^(-1) at 1.0 A g^(-1) . The results are beneficial for the development of Zn/Mn_(3)O_(4) battery for practical energy storage. | Xiuli Guo Hao Sun Chunguang Li Siqi Zhang Zhenhua Li Xiangyan Hou Xiaobo Chen Jingyao Liu Zhan Shi Shouhua Feng | 2022 | Journal of Energy Chemistry2022，31，5： | 1 |
| 12 | Fabrication of in situ Ti_2AlN/TiAl Composites by Reaction Hot Pressing and Their Properties显示文摘Ti2AlN/TiAl composites with different volume fractions of reinforcement were successfully fabricated by hot-pressing sintering method(reaction hot pressing) using Ti, Al and TiN powders as starting materials. The synthesis process includes four stages: first, the reactions between Al and Ti powers and between Al and TiN powders respectively occur and result in TiAl3 phase; secondly, Al powders in the sample are exhausted; the remaining Ti cores react with TiAl3 layer to form Ti-Al intermetallics; moreover, a few Ti2AlN particles precipitate from the TiAl3 phase; thirdly, Ti-Al intermetallics react with the remaining Ti cores to form Ti3Al and TiAl phases. TiAl phase and original TiN powers are in direct contact each other; finally, the residual TiN powers react with TiAl phase and result in a plenty of Ti2AlN phase. Compared with TiAl matrix, the hardness, elastic modulus and high-temperature compressive strength of Ti2AlN/TiAl composite are improved obviously and they are all enhanced with increasing the volume fraction of Ti2AlN phase. | 孙东立 SUN Tao WANG Qing HAN Xiuli GUO Qiang WU Gaohui | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，1： | 1 |

| 17 | Performance of anaerobic fluidized bed microbial fuel cell with different porous anodes显示文摘Anode materials were used to construct microbial fuel cells(MFCs),and the characteristics of the anodes were important for successful applied performance of the MFCs.Via the cyclic voltammetry(CV)method,the experiments showed that 5 wt%multiwalled carbon nanotubes(MWNTs)were optimal for the PANI/MWNT film anodes prepared using 24 polymerization cycles.The maximum output voltage of the PANI/MWNT film anodes reached 967.7 mV with a power density of 286.63 mW·m-2.Stable output voltages of 860 mV,850 mV,and870 mV were achieved when the anaerobic fluidized bed microbial fuel cell(AFBMFC)anodes consisted of carbon cloth with carbon black on one side,copper foam and carbon brushes,respectively.Pretreatment of the anodes before starting the AFBMFC by immersion in a stirred bacterial fluid significantly shortened the AFBMFC startup time.After the AFBMFC was continuously run,the anode surfaces generated active microbial catalytic material. | Xiuli Zhang Chunhu Li Qingjie Guo Kelei Huang | 2020 | Chinese Journal of Chemical Engineering2020，28，3： | 1 |
| 18 | Responses of Soil Bacterial Diversity to Fertilization are Driven by Local Environmental Context Across China显示文摘Soil microbial diversity is extremely vulnerable to fertilization,which is one of the main anthropogenic activities associated with global changes.Yet we know little about how and why soil microbial diversity responds to fertilization across contrasting local ecological contexts.This knowledge is fundamental for predicting changes in soil microbial diversity in response to ongoing global changes.We analyzed soils from ten 20-year field fertilization(organic and/or inorganic)experiments across China and found that the national-scale responses of soil bacterial diversity to fertilization are dependent on ecological context.In acidic soils from regions with high precipitation and soil fertility,inorganic fertilization can result in further acidification,resulting in negative impacts on soil bacterial diversity.In comparison,organic fer-tilization causes a smaller disturbance to soil bacterial diversity.Despite the overall role of environmental contexts in driving soil microbial diversity,a small group of bacterial taxa were found to respond to fer-tilization in a consistent way across contrasting regions throughout China.Taxa such as Nitrosospira and Nitrososphaera,which benefit from nitrogen fertilizer addition,as well as Chitinophagaceae,Bacilli,and phototrophic bacteria,which respond positively to organic fertilization,could be used as bioindicators for soil fertility in response to fertilization at the national scale.Overall,our work provides new insights into the importance of local environmental context in determining the responses of soil microbial diver-sity to fertilization,and identifies regions with acidic soils wherein soil microbial diversity is more vul-nerable to fertilization at the national scale. | Youzhi Feng Manuel Delgado-Baquerizo Yongguan Zhu Xiaozeng Han Xiaori Han Xiuli Xin Wei Li Zhibing Guo Tinghui Dang Chenhua Li Bo Zhu Zejiang Cai Daming Li Jiabao Zhang | 2022 | Engineering2022，8，5： | 1 |
| 19 | SIRT7 orchestrates melanoma progression by simultaneously promoting cell survival and immune evasion via UPR activation显示文摘Melanoma is the most lethal type of skin cancer,originating from the malignant transformation of melanocyte.While the development of targeted therapy and immunotherapy has gained revolutionary advances in potentiating the therapeutic effect,the prognosis of patients with melanoma is still suboptimal.During tumor progression,melanoma frequently encounters stress from both endogenous and exogenous sources in tumor microenvironment.SIRT7 is a nuclear-localized deacetylase of which the activity is highly dependent on intracellular nicotinamide adenine dinucleotide(NAD+),with versatile biological functions in maintaining cell homeostasis.Nevertheless,whether SIRT7 regulates tumor cell biology and tumor immunology in melanoma under stressful tumor microenvironment remains elusive.Herein,we reported that SIRT7 orchestrates melanoma progression by simultaneously promoting tumor cell survival and immune evasion via the activation of unfolded protein response.We first identified that SIRT7 expression was the most significantly increased one in sirtuins family upon stress.Then,we proved that the deficiency of SIRT7 potentiated tumor cell death under stress in vitro and suppressed melanoma growth in vivo.Mechanistically,SIRT7 selectively activated the IRE1α-XBP1 axis to potentiate the pro-survival ERK signal pathway and the secretion of tumorpromoting cytokines.SIRT7 directly de-acetylated SMAD4 to antagonize the TGF-β-SMAD4 signal,which relieved the transcriptional repression on IRE1αand induced the activation of the IRE1α-XBP1 axis.Moreover,SIRT7 up-regulation eradicated anti-tumor immunity by promoting PD-L1 expression via the IRE1α-XBP1 axis.Additionally,the synergized therapeutic effect of SIRT7 suppression and anti-PD-1 immune checkpoint blockade was also investigated.Taken together,SIRT7 can be employed as a promising target to restrain tumor growth and increase the effect of melanoma immunotherapy. | Xiuli Yi Huina Wang Yuqi Yang Hao Wang Hengxiang Zhang Sen Guo Jianru Chen Juan Du Yangzi Tian Jingjing Ma Baolu Zhang Lili Wu Qiong Shi Tianwen Gao Weinan Guo Chunying | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 1 |
| 20 | Strigolactone and gibberellin signaling coordinately regulate metabolic adaptations to changes in nitrogen availability in rice显示文摘Modern semi-dwarf rice varieties of the“Green Revolution”require a high supply of nitrogen(N)fertilizer to produce high yields.A better understanding of the interplay between N metabolism and plant developmental processes is required for improved N-use efficiency and agricultural sustainability.Here,we show that strigolactones(SLs)modulate root metabolic and developmental adaptations to low N availability for ensuring efficient uptake and translocation of available N.The key repressor DWARF 53(D53)of the SL signaling pathway interacts with the transcription factor GROWTH-REGULATING FACTOR 4(GRF4)and prevents GRF4 from binding to its target gene promoters.N limitation induces the accumulation of SLs,which in turn promotes SL-mediated degradation of D53,leading to the release of GRF4 and thus promoting the expression of genes associated with N metabolism.N limitation also induces degradation of the DELLA protein SLENDER RICE 1(SLR1)in an D14-and D53-dependent manner,effectively releasing GRF4 from competitive inhibition caused by SLR1.Collectively,our findings reveal a previously unrecognized mechanism underlying SL and gibberellin crosstalk in response to N availability,advancing our understanding of plant growth–metabolic coordination and facilitating the design of the strategies for improving N-use efficiency in high-yield crops. | Huwei Sun Xiaoli Guo Xiuli Zhu Pengyuan Gu Wei Zhang Wenqing Tao Daojian Wang Yunzhe Wu Quanzhi Zhao Guohua Xu Xiangdong Fu Yali Zhang | 2023 | Molecular Plant2023，16，3： | 1 |
