1Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management.Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng 2015Chinese Birds2015,,3:20
2Extracellular Signal-Regulated Kinase in Nucleus Accumbens Mediates Propofol Self-Administration in Rats显示文摘Clinical and animal studies have indicated that propofol has potential for abuse,but the specific neurobiological mechanism underlying propofol reward is not fully understood.The purpose of this study was to investigate the role of extracellular signal-regulated kinase(ERK) signal transduction pathways in the nucleus accumbens(NAc) in propofol self-administration.We tested the expression of p-ERK in the NAc following the maintenance of propofol self-administration in rats.We also assessed the effect of administration of SCH23390,an antagonist of the D1 dopamine receptor,on the expression of p-ERK in the NAc in propofol self-administering rats,and examined the effects of intra-NAc injection of U0126,an MEK inhibitor,on propofol reinforcement in rats.The results showed that the expression of p-ERK in the NAc increased significantly in rats maintained on propofol,and pre-treatment with SCH23390 inhibited the propofol selfadministration and diminished the expression of p-ERK in the NAc.Moreover,intra-NAc injection of U0126(4 μg/side) attenuated the propofol self-administration.The data suggest that ERK signal transduction pathways coupled with D1 dopamine receptors in the NAc may be involved in the maintenance of propofol self-administration and its rewarding effects.Benfu Wang Xiaowei Yang Anna Sun Lanman Xu Sicong Wang Wenxuan Lin Miaojun Lai Huaqiang Zhu Wenhua Zhou Qingquan Lian 2016Neuroscience Bulletin2016,32,6:12
3Domain structure and defects of highly ordered Bi_4Si_3O_(12) micro-crystals显示文摘Highly ordered Bi4Si3O12 micro-crystals were prepared at normal atmosphere. Phase identification of the prepared crystals was accomplished by X-ray diffractometer (XRD). Domain structure and defects were characterized by environmental scanning electron microscopy (ESEM). XRD shows that the obtained micro-crystals are of eulytite structure with chemical formulation of Bi4Si3O12. A highly ordered growth pattern is confirmed due to the faster growth of the {124} faces than that of the {204} faces by ESEM. The growing process of the domain structure is of pollen parent and filial generation pattern. The filial generations of Bi4Si3O12 crystals are generated from the pollen parent. Cracks generate from the defect areas and propagate along the {124} faces due to their lower binding energy under a proper temperature gradient, contributing to the total transcrystalline fracture. It is confirmed that the generation and development of the voids in the crystal grains can be developed when unmatched dimensions of the two opposite faces are formed. And the development of the voids is dependent on the dimensions and orientations of the two opposite faces.TIAN QingQuan, WANG XiuFeng, YU ChengLong, JIANG HongTao, ZHANG ZhengGuang, WANG Yan & LIN SheBao School of Materials Science and Engineering, Shaanxi University of Science & Technology, Xi’an 710021, China 2009Science China(Technological Sciences)2009,52,8:8
4Study on hydrometallurgical process and kinetics of manganese extraction from low-grade manganese carbonate ores显示文摘In order to utilize low-grade manganese ore resources effectively, a hydrometallurgical process was developed for manganese extraction in dilute sulfuric acid medium, and the kinetics of leaching manganese was also investigated. At room temperature, manganese from low-grade manganese carbonate ores was extracted by sulfuric acid leaching without reductants. During the extracting process, single-factor analysis method was used to evaluate the effects of grinding fineness, sulfuric acid concentration,liquid-to-solid ratio, agitation rate and leaching time on the leaching efficiencies of Mn and Fe. The optimal leaching conditions are determined as coarse particles of below 2 mm size(without ball-milling),sulfuric acid concentration of 0.86 mol/L, liquid-to-solid ratio of 5:1, agitation rate of 150 r/min and leaching for 180 min at room temperature. Under the optimal conditions, the leaching efficiencies of Mn and Fe are 96.21% and 13.35%, respectively. In addition, through the experiments at different temperatures, it is found that the leaching process follows the shrinking core model under the conditions of changing acid concentration and intermittent reaction device. Moreover, the apparent activations of effective diffusion and chemical reaction in the kinetic model are calculated to be 18.83 and27.15 kJ/mol, respectively.Liu Youcai Lin Qingquan Li Lifeng Fu Jiangang Zhu Zhongsi Wang Chongqing Qian Dong 2014International Journal of Mining Science and Technology2014,24,4:6
5Unique catalysis of Ni-Al hydrotalcite derived catalyst in CO_2 methanation: cooperative effect between Ni nanoparticles and a basic support显示文摘Ni-Al hydrotalcite derived catalyst(Ni-Al2O3-HT) exhibited a narrow Ni particle-size distribution with an average particle size of 4.0 nm.Methanation of CO2 over this catalyst initiated at 225℃ and reached 82.5% CO2 conversion with 99.5% CH4 selectivity at 350℃, which was much better than its impregnated counterpart. Characterizations by means of CO2 microcalorimetry and 27Al NMR indicated that large amount of strong basic sites existed on Ni-Al2O3-HT, originated from the formation of Ni-O-Al structure. The existence of strong basic sites facilitated the activation of CO2 and consequently promoted the activity. The combination of highly dispersed Ni with strong basic support led to its unique and high efficiency for this reaction.Lei He Qingquan Lin Yu Liu Yanqiang Huang 2014Journal of Energy Chemistry2014,23,5:5
6CO_2 methanation over TiO_2–Al_2O_3 binary oxides supported Ru catalysts显示文摘TiO_2 modified Al_2O_3 binary oxide was prepared by a wet-impregnation method and used as the support for ruthenium catalyst. The catalytic performance of Ru/TiO_2–Al_2O_3catalyst in CO_2 methanation reaction was investigated. Compared with Ru/Al_2O_3 catalyst, the Ru/TiO_2–Al_2O_3catalytic system exhibited a much higher activity in CO_2 methanation reaction. The reaction rate over Ru/TiO_2–Al_2O_3 was 0.59 mol CO_2·(g Ru)1·h-1, 3.1 times higher than that on Ru/Al_2O_3[0.19 mol CO_2·(gRu)-1·h-1]. The effect of TiO_2 content and TiO_2–Al_2O_3calcination temperature on catalytic performance was addressed. The corresponding structures of each catalyst were characterized by means of H_2-TPR, XRD, and TEM. Results indicated that the averaged particle size of the Ru on TiO_2–Al_2O_3support is 2.8 nm, smaller than that on Al_2O_3 support of 4.3 nm. Therefore, we conclude that the improved activity over Ru/TiO_2–Al_2O_3catalyst is originated from the smaller particle size of ruthenium resulting from a strong interaction between Ru and the rutile-TiO_2 support, which hindered the aggregation of Ru nanoparticles.Jinghua Xu Qingquan Lin Xiong Su Hongmin Duan Haoran Geng Yanqiang Huang 2016Chinese Journal of Chemical Engineering2016,24,1:4

9Enhanced N_(2)-to-NH_(3)conversion efficiency on Cu3P nanoribbon electrocatalyst显示文摘Ambient electroreduction of nitrogen(N_(2))is considered as a green and feasible approach for ammonia(NH_(3))synthesis,which urgently demands for efficient electrocatalyst.Morphology has close relationship with catalytic activity of heterogeneous catalysts.Nanoribbon is attractive nanostructure,which possesses the flexibility of one-dimensional nanomaterials,the large surface area of two-dimensional nanomaterials,and lateral size confinement effects.In this work,Cu_(3)P nanoribbon is proposed as a highly efficient electrocatalyst for N_(2)-to-NH_(3)conversion under benign conditions.When measured in N_(2)-saturated 0.1 M HCl,such Cu_(3)P nanoribbon achieves high performance with an excellent Faradaic efficiency as high as 37.8%and a large yield of 18.9μg·h^(−1)·mgcat.−1 at−0.2 V.It also demonstrates outstanding stability in long-term electrolysis test at least for 45 h.Qian Liu Yiting Lin Shuang Gu Ziqiang Cheng Lisi Xie Shengjun Sun Longcheng Zhang Yongsong Luo Abdulmohsen Ali Alshehri Mohamed SHamdy Qingquan Kong Jiahong Wang Xuping Sun 2022Nano Research2022,15,8:1

15Bi nanoparticles/carbon nanosheet composite:A high-efficiency electrocatalyst for NO reduction to NH_(3)显示文摘Electrochemical reduction of NO offers us an attractive alternative to traditional selective catalytic reduction process for harmful NO removal and simultaneous NH_(3)production,but it requires efficient electrocatalyst to enable the NO reduction reaction with high selectivity.Here,we report on the development of Bi nanoparticles/carbon nanosheet composite(Bi@C)for highly effective NO reduction electrocatalysis toward selective NH_(3)formation.Such Bi@C catalyst attains an impressive NH_(3)yield of 1,592.5μg·h^(−1)·mgcat.^(−1)and a high Faradaic efficiency as high as 93%in 0.1 M Na_(2)SO_(4)electrolyte.Additionally,it can be applied as efficient cathode materials for Zn–NO battery to reduce NO to NH_(3)with high electricity generation.Qian Liu Yiting Lin Luchao Yue Jie Liang Longcheng Zhang Tingshuai Li Yongsong Luo Meiling Liu Jinmao You Abdulmohsen Ali Alshehri Qingquan Kong Xuping Sun 2022Nano Research2022,15,6:0
16Simultaneous Thermoluminescence and Thermally Stimulated Current in Polyamide显示文摘We have obtained simultaneous thermoluminescence (TL) and thermally Stimulated current (TSC) spectra in two types of polyamide film, such as nylons 6 and 11 under study of electron detrapping and recombination. There are three main relaxation peaks or regions, designated γ,β and α in order of increasing temperature in the TSC spectra, in contrast, a high temperature relaxation peak in TL spectra disappears. The centers or peaks of these relaxation regions are located at near 180, 230 and 310 K, respectively, deviating±10 K. However. we also observed two anomalous phenomena: first, a very large, short-circuited, thermally stimulated discharge current (TSDC) up to 10-8 A, but reversible in direction for non-polarized nylons 6 and 11, even after several times repeatedly; secondly, no TL signal except for non-polarized nylon 6 film.Fan, Yong Wang, Xuan Zhang, Xiaohong Lin, Jiaqi Lei, Qingquan 1998Journal of Materials Science & Technology1998,14,4:0
17Behaviour and mechanisms of molecular vibrations induced by a pulsed voltage in a silicone elastomer used for device encapsulation显示文摘Silicone elastomers are widely used to encapsulate power electronic devices.However,such devices may be subjected to square‐wave pulsed voltages with a high rate of change,which can create significant challenges for encapsulation insulation.In this article,the molecular vibration of silicon elastomer at the edge of pulsed electric field is studied.Firstly,the relationship between the intensity of molecular vibration and the parameters of pulsed electric field is explored.The experimental results show that the amplitude of the vibrations decreases as the pulse‐edge time increases,and it increases linearly as the pulseedge slope increases.Furthermore,the amplitude of the vibrations is proportional to the square of the amplitude of the pulsed electric field,and it increases as the space charge density increases.Then,the force analysis of charged molecule at the pulse edges is calculated,and the theoretical change law of molecular vibration intensity with pulse edge slope is deduced.Comparing the theoretical results with the experimental results,it is found that they are highly consistent.Finally,electrically induced mechanical stress caused by molecular vibration was shown to be an important factor in insulation failure.Junyu Wei Dongxin He Teng Gao Lin Zhu Haochen Wang Qingquan Li Gilbert Teyssedre 2023High Voltage2023,8,5:0
18enOsCas12f1-mediated exon skipping for Duchenne muscular dystrophy therapy in humanized mouse model显示文摘Duchenne muscular dystrophy(DMD)is a severe neuromuscular disorder caused by mutations in the dystrophin gene,which encodes the essential protein dystrophin.This genetic condition,affecting approximately 1 in 5000 male births worldwide(Birnkrant et al.,2018),is characterized by progressive muscle weakness and wasting,leading to premature death in the second or third decade of life(Farini et al.,2016).The absence of dystrophin protein causes instability in the sarcolemma,which predisposes individuals to myonecrosis and activation of inflammatory signaling cascades.Unfortunately,there is currently no effective cure for DMD,and glucocorticoid steroids are commonly used in clinical settings to delay symptom development(Merlini et al.,2003).Ming Jin Jiajia Lin Yu Zhang Qingquan Xiao Xiangfeng Kong Xiumei Zhang Zhurui Shao Yin Wang Yuyang Yu Jinjing Li Wan-Jin Chen Guoling Li Hui Yang Ning Wang 2024Journal of Genetics and Genomics2024,51,2:0
19Comparison of the Effects of Pesticide Application on Biston suppressaria Larvae in Different Damage Stages显示文摘[Objective] The paper was to determine the optimal control period of Biston suppressaria, the most serious defoliator in eucalyptus forests in southern Fujian Province. [Method] By spraying 2% abamectin + Bacilus thuringiensis powder in the forest, the first generation larvae of B. suppressaria was controlled in the early damage stage(May 2), middle damage stage(May 13) and late damage stage(May 30), respectively.[Result] When 500 g of pesticide was sprayed per 667 m^(2) in the early damage stage of the first generation larvae, the population reduction rate was97.5 % at 5 d post spraying. When 500 g of pesticide was sprayed per 667 m^(2) in the middle damage stage, the population reduction rate was 95.3% at 5 d post spraying. When 1 000 g of pesticide was sprayed per 667 m^(2) in the late damage stage, the population reduction rate was 83.9%, conspicuously lower than those in the early and middle damage stage. If pesticides were sprayed in the early and middle damage stage, the second gen-eration larvae would not cause harms, but the second generation larvae would cause slight harms if pesticides were sprayed in the late damage stage.[Conclusion] Control before the middle damage stage has significant effect on improving the control effect and reducing losses while reducing the usage of pesticides.Hezai Lin Shouping Cai Xueyou He Liqiong Zeng Haitian Song Qingquan Wu 2021Plant Diseases and Pests2021,12,3:0
20Anion-cation dual doping: An effective electronic modulation strategy of Ni2P for high-performance oxygen evolution显示文摘Developing of high-performance and low-cost electrocatalysts is of great significance to reduce the overpotential and accelerated the reaction rate of oxygen evolution in water splitting and related energy conversion applications.Herein,Fe,O-dual doped Ni2P(Fe,O-Ni2P)nanoarray is successfully synthesized on carbon cloth demonstrating enhanced electrocatalytic activity and stability for oxygen evolution reaction(OER)under alkaline media.The as-synthesized Fe,O-Ni2P nanoarray exhibits obviously improved OER performance with a low overpotential of 210 mV at 10 mA cm^-2 current density and a Tafel slope of48 mV dec^-1,as well as long-term durability.The strong coupling interaction induced changes in electronic structure lead to relatively higher oxidation state and stronger oxidation ability of the Fe,O-Ni2P nanoarray,together with the high electrochemical surface area and good conductivity contribute to the superior OER performance.This work highlights the anion-cation dual doping strategy may be an effective method for fabrication of catalysts relating to energy conversion applications.Bo Xu Xiaodong Yang Qiang Fang Linbing Du Yan Fu Yiqiang Sun Qisheng Liu Qingquan Lin Cuncheng Li 2020Journal of Energy Chemistry2020,29,9:0
