| 1 | Long-term changes of phytoplankton community in Xiagu waters of Xiamen,China显示文摘Long-term changes of phytoplankton community by water sampling method in Xiagu Sea waters of Xiamen,China,were investigated in this study.Species composition of the phytoplankton community in these waters changed greatly since the 1950s.The numbers of Dinophyta species increased significantly,although Bacillariophyta species are generally dominant.The succession of dominant species in phytoplankton community is obvious: large-size dominant species such as Biddulphia sinensis of the 1950s were gradually replaced by small-size ones such as Cyclotella striata and Nitzschia closterium,and species that still maintain dominant such as Skeletonema costatum are also small ones,leading the whole phytoplankton community of smaller size.Cell density of phytoplankton community increased greatly,among which cell density of the most dominant species Skeletonema costatum have been increasing in exponent function.Margalef index of phytoplankton community decreased,indicating decline of biodiversity of the community,and dominant character of Skeletonema costatum increased.Generally,the structure of the entire phytoplankton community is becoming more and more singular and unstable,which makes the occurrence of red tides more frequent.The succession in the phytoplankton community is related to the long-term changes in marine environment,influenced by human activities and global climate changes,especially the increases of nutrient content. | CHEN Baohong XU Zhuhua ZHOU Qiulin CHEN Changping GAO Yahui YANG Shengyun JI Weidong | 2010 | Acta Oceanologica Sinica2010，29，6： | 14 |
| 2 | Multifunctional roles of carbon-based hosts for Li-metal anodes:A review显示文摘With its high theoretical capacity,lithium(Li)metal is recognized as the most potential anode for realizing a high-performance energy storage system.A series of questions(severe safety hazard,low Coulombic efficiency,short lifetime,etc.)induced by uncontrollable dendrites growth,unstable solid electrolyte interface layer,and large volume change,make practical application of Li-metal anodes still a threshold.Due to their highly appealing properties,carbon-based materials as hosts to composite with Li metal have been passionately investigated for improving the performance of Li-metal batteries.This review displays an overview of the critical role of carbon-based hosts for improving the comprehensive performance of Li-metal anodes.Based on correlated mainstream models,the main failure mechanism of Li-metal anodes is introduced.The advantages and strategies of carbon-based hosts to address the corresponding challenges are generalized.The unique function,existing limitation,and recent research progress of key carbon-based host materials for Li-metal anodes are reviewed.Finally,a conclusion and an outlook for future research of carbon-based hosts are presented.This review is dedicated to summarizing the advances of carbon-based materials hosts in recent years and providing a reference for the further development of carbonbased hosts for advanced Li-metal anodes. | Xiaolin Yan Liang Lin Qiulin Chen Qingshui Xie Baihua Qu Laisen Wang Dong-Liang Peng | 2021 | Carbon Energy2021，3，2： | 8 |
| 3 | Catalytic methanol decomposition to carbon monoxide and hydrogen over Pd/CeO_2-ZrO_2-La_2O_3 with different Ce/Zr molar ratios显示文摘The catalytic behaviors of Pd (1.4 wt%) catalysts supported on CeO2-ZrO2-La2O3 mixed oxides with different Ce/Zr molar ratios were investigated for methanol decomposition. Nitrogen adsorption-desorption (BET), X-ray photoelectron spectroscopy (XPS), H2 temperature-programmed reduction (H2-TPR), X-ray diffraction (XRD) and Pd dispersion analysis were used for their characterization. Pd/Ce0.76Zr0.18 La0.06O1.97 catalyst showed the highest BET surface area, best Pd dispersion capability and strongest metal-support interaction. Moreover, XPS showed that there was lattice defect oxygen or mobile oxygen. According to the result of O 1s measurements the lattice defect oxygen or mobile oxygen helped to maintain Pd in a partly oxidized state and increased the activity for methanol decomposition. The Pd/Ce0.76Zr0.18La0.06O1.97 catalyst exhibited the best activity. A 100% conversion of methanol was achieved at around 260℃, which was about 20-40℃ lower than other | Hairong Wang Yaoqiang Chen Qiulin Zhang Qingchao Zhu Maochu Gong Ming Zhao | 2009 | Journal of Natural Gas Chemistry2009，18，2： | 6 |
| 4 | Homogeneous bottom-growth of lithium metal anode enabled by double-gradient lithiophilic skeleton显示文摘Lithium(Li) metal is considered as the most promising anode material for the next-generation high performance Li batteries.However,the uncontrollable dendritic growth impedes its commercial application.Herein,we design a 3 D Si@carbon nanofibers(CNFs)@ZnO-ZnO-Cu skeleton(SCZ) for guiding the homogeneous bottom-growth of Li metal.The top LixSi@CNFs and bottom LiyZn@CNFs layers could form conductivity and overpotential gradient to avoid the 'top-growth' of Li metal.Moreover,the top lithiophilic LixSi@CNFs layer could regulate the nucleation and deposition of Li-ions even if the lithium dendrites grow out of the skeleton under high capacity Li deposition(30 mAh cm^(-2)).As a result,the SCZ-Li||LiFePO_(4) full cell delivers a high capacity of ~104 mAh g^(-1)(~94.82% capacity retention) after 2000 cycles at 5 C, elucidating the potential application of the 3 D double-gradient Li metal composite anode. | Li Zhang Hongfei Zheng Ben Liu Qingshui Xie Qiulin Chen Liang Lin Jie Lin Baihua Qu Laisen Wang Dong-Liang Peng | 2021 | Journal of Energy Chemistry2021，30，6： | 5 |
| 5 | Localization and characterization of the hypothetical protein CT440 in Chlamydia trachomatis-infected cells显示文摘The inclusion membrane proteins play potentially important roles in chlamydial biology and pathogenesis.Here we localized and characterized the hypothetical protein CT440 in Chlamydia trachomatis-infected cells.The open reading frame(ORF) encoding the CT440 protein from the C.trachomatis serovar D genome was cloned into the prokaryotic expression vector pGEX-6p and expressed as a glutathione-S-transferase(GST) fusion protein in E.coli XL1-Blue.The CT440 fusion protein was used to immunize mice to raise antigen-specific antibody.After verification by Western blot and immunofluorescence assay(IFA),the specific antibody was used to localize the endogenous CT440 protein and to detect its expression pattern in Chlamydia-infected cells.Cytosolic expression of CT440 in HeLa cells was also carried out to evaluate the effect of the CT440 protein on the subsequent chlamydial infection.The results showed that the hypothetical protein CT440 was localized in the C.trachomatis inclusion membrane,and was detectable 12 h after chlamydial infection.Expression of CT440 in the cytoplasm did not inhibit the subsequent chlamydial infection.In summary,we have identified a new inclusion membrane protein that may be an important candidate for understanding C.trachomatis pathogenesis. | LI ZhongYu HUANG QiuLin SU ShengMei ZHOU Zhou CHEN ChaoQun ZHONG GuangMing WU YiMou | 2011 | Science China(Life Sciences)2011，54，11： | 5 |
| 6 | End of the First Demographic Dividend and Possible Labor Market Response in China and Other Asian Countries(Regions)显示文摘This paper sheds light on the nexus of age compositional shifts and the generation of the first demographic dividend over the past several decades in China,and also discusses how this dividend could be extended.We first estimate how long China's first demographic dividend will last and then compare the computed results for China with those for other selected Asian countries in order to place the Chinese case in a wider perspective.Furthermore,in view of the possibility that China's first demographic dividend will turn negative in 2014,we offer insight into how and to what extent China's labor market needs to adjust and how much labor income must increase for the first demographic dividend to remain positive up to year2050.For this goal to be achieved,the labor income age profile needs to be shifted to a considerable extent.We conduct an exercise in which the 2007 peak labor income age of 32years is shifted to 40years.In the case of the elderly,this implies an annual labor income growth of 3.1 percent over the period of 39 years.Throughout this paper,we draw on a variety of computed results derived from the Chinese component of the global'National Transfer Accounts'project. | Naohiro Ogawa Qiulin Chen | 2013 | China & World Economy2013，21，2： | 5 |
| 7 | Evolution of urban black and odorous water:The characteristics of microbial community and driving-factors显示文摘Urban black blooms that are primarily caused by organic carbon are deleterious environmental problems.However,detailed studies on the microbial characteristics that form urban black blooms are lacking.In this study,we observed the composition,diversity,and function of bacterial community in the overlying water and sediments during the occurrence and remediation of urban black blooms using high-throughput 16S rRNA gene amplicon sequencing analysis.First,we found that pivotal consortia in the overlying water increased significantly during the formation of black blooms,including the genera Acidovorax,Brevundimonas,Pusillimonas,and Burkholderiales involved in the degradation of refractory organics,as well as the genera Desulfovibrio,Dechloromonas,and Rhizobium related to the production of black and odorous substances.An RDA analysis revealed that chemical oxygen demand,dissolved oxygen,and oxidation reduction potential were related to the changes in microbial community composition.Furthermore,aeration was found to accelerate the removal of ammonia nitrogen and enhance the function of microbial community by stimulating the growth of order Planktomycetes during the remediation of black blooms,but aeration substantially damaged the microbial diversity and richness.Therefore,the health of the aquatic ecosystem should be comprehensively considered when aeration is applied to restore polluted waterbodies.Notably,we observed a large number of pathogenic bacteria in urban black blooms,which emphasizes the importance of treating domestic sewage so that it is harmless.Together,these findings provide new insights and a basis to prevent and manage urban black blooms. | Dan Zhang Huilan Yang Shuhuan Lan Chen Wang Xudong Li Yunxiao Xing Hua Yue Qiulin Li Ling Wang Yifei Xie | 2022 | Journal of Environmental Sciences2022，34，2： | 4 |
| 8 | Interfacial engineering of Ni/V2O3 for hydrogen evolution reaction显示文摘Electrocatalytic water splitting offers a sustainable route for hydrogen production,enabling the clean and renewable alternative energy system of hydrogen economy.The scarcity and high-cost of platinum-group-metal(PGM)materials urge the exploration of high-performance non-PGM electrocatalysts.Herein,a unique hierarchical structure of NiA/2O3 with extraordinary electrocatalytic performance(e.g.t overpotentials as low as 22 mV at 20 mA·cm^-2 and 94 mV at 100 mA·cm^-2)toward hydrogen evolution reaction in alkaline electrolyte(1 M KOH)is reported.The investigation on the hierarchical NiA/2O3 with a bimodal size-distribution also offers insight of interfacial engineering that only proper NiA/2O3 interface can effectively improve H20 adsorption,H20 dissociation as well as H adsorption,for an efficient hydrogen production. | Yang Chen Yuan Rao Rongzhi Wang Yanan Yu Qiulin Li Shujuan Bao Maowen Xu Qin Yue Yanning Zhang Yijin Kang | 2020 | Nano Research2020，13，9： | 3 |

| 10 | Generation of spatial atmospheric turbulence field in aircraft motion simulation based on refined similarity hypothesis显示文摘It is necessary to build turbulence model to study the response of aircraft to atmospheric turbulence for high resolution earth observation. The conventional method is on the basis of Dryden’s model with the assumption that individual patches are Gaussian. In this paper,based on Kraichnan’s refined similarity idea,a new 1D atmospheric turbulence model is set up by introducing the energy transfer rate as an intermittency disturbance to a Gaussian process. Our results show that the turbulent fields generated by our new method exhibit an anomalous scaling described by the She-Leveque (SL) formula,which is now well accepted for homogenous and isotropic turbulence. | GUO Hao CHEN JingJing QU QiuLin LIU PeiQing | 2011 | Science China(Technological Sciences)2011，54，1： | 1 |

| 13 | Seamless and early gap healing of osteochondral defects by autologous mosaicplasty combined with bioactive supramolecular nanofiber-enabled gelatin methacryloyl(BSN-GelMA)hydrogel显示文摘Autologous mosaicplasty is a common approach used to treat osteochondral defects in clinical practice.Gap integration between host and transplanted plugs requires bone tissue reservation and hyaline cartilage regeneration without uneven surface,graft necrosis and sclerosis.However,poor gap integration is a serious concern,which eventually leads to deterioration of joint function.To deal with such complications,this study has developed a strategy to effectively enhance integration of the gap region following mosaicplasty by applying injectable bioactive supramolecular nanofiber-enabled gelatin methacryloyl(GelMA)hydrogel(BSN-GelMA).A rabbit osteochondral defect model demonstrated that BSN-GelMA achieved seamless osteochondral healing in the gap region between plugs of osteochondral defects following mosaicplasty,as early as six weeks.Moreover,the International Cartilage Repair Society score,histology score,glycosaminoglycan content,subchondral bone volume,and collagen II expression were observed to be the highest in the gap region of BSN-GelMA treated group.This improved outcome was due to bio-interactive materials,which acted as tissue fillers to bridge the gap,prevent cartilage degeneration,and promote graft survival and migration of bone marrow mesenchymal stem cells by releasing bioactive supramolecular nanofibers from the GelMA hydrogel.This study provides a powerful and applicable approach to improve gap integration after autologous mosaicplasty.It is also a promising off-the-shelf bioactive material for cell-free in situ tissue regeneration. | Hongwei Wu Yuna Shang Wei Sun Xinyi Ouyang Wenyan Zhou Jieji Lu Shuhui Yang Wei Wei Xudong Yao g Xiaozhao Wang Xianzhu Zhang Yishan Chen Qiulin He Zhimou Yang Hongwei Ouyang | 2023 | Bioactive Materials2023，，1： | 1 |

| 15 | The prewarning value of Alexandrium tamarense PSP in an area with frequent outburst of red tide显示文摘The PSP toxicity of Alexandrium tamarense (Lebour) Balech on the blue mussel (Mytilus edulis) from the western waters of Xiamen in China was studied by following the standard method of PSP mouse bioassay developed by the Association of Official Analytical Chemists (AOAC). The results showed that the mice survived when the density of A. tamarense cells was lower than 1×105 cells per cubic decimetre and died when the density was higher than 1×106 cells per cubic decimetre. The past record of red tide events in the western waters of Xiamen showed a general trend of starting from the bloom of non-toxic planktonic diatoms in local waters and resulting in a harmful algal bloom due to the fade of planktonic diatoms which failed in the survival competition in the unfavorable and deteriorated eco-environment. On the basis of experimental results and natural environment of Xiamen waters and by making reference to the critical criteria of shellfish toxins in various states, a prewarning value 1×105 cells per cubic decimetre of A. tamarense PSP toxicity was proposed for the areas in South China where red tides frequently occur. | JI Weidong ZHOU Qiulin HUO Wenmian CHEN Weifen LIN Hui HE Qing CHEN Baohong LIANG Junrong GAO Yahui HUANG Deqiang LI Yang | 2007 | Acta Oceanologica Sinica2007，26，1： | 0 |
| 16 | Mesh model building and migration and accumulation simulation of 3D hydrocarbon carrier system显示文摘Migration and accumulation simulation of oil and gas in carrier systems has always been a difficult subject in the quantitative study of petroleum geology. In view of the fact that the traditional geological modeling technology can not establish the interrelation of carriers in three dimensional space, we have proposed a hybrid-dimensional mesh modeling technology consisting of body(stratum), surfaces(faults and unconformities), lines and points, which provides an important research method for the description of geometry of sand bodies, faults and unconformities, the 3 D geological modeling of complex tectonic areas, and the simulation of hydrocarbon migration and accumulation. Furthermore, we have advanced a 3 D hydrocarbon migration pathway tracking method based on the hybrid-dimensional mesh of the carrier system. The application of this technology in western Luliang Uplift of Junggar Basin shows that the technology can effectively characterize the transport effect of fault planes, unconformities and sand bodies, indicate the hydrocarbon migration pathways, simulate the process of oil accumulation, reservoir adjustment and secondary reservoir formation, predict the hydrocarbon distribution. It is found through the simulation that the areas around the paleo-oil reservoir and covered by migration pathways are favorable sites for oil and gas distribution. | GUO Qiulin LIU Jifeng CHEN Ningsheng WU Xiaozhi REN Hongjia WEI Yanzhao CHEN Gang GONG Deyu YUAN Xuanjun | 2018 | Petroleum Exploration and Development2018，45，6： | 0 |
| 17 | SHTQS: a telephonebased Chinese spoken dialogue system显示文摘SHTQS is an intelligent telephonebased spoken dialogue system providing the information about the best route between two sites in Shanghai. Instead of separated parts of speech decoding and language parsing, a close cooperation is carried out in SHTQS by integrating automatic speech recognizer (ASR), language understanding, dialogue management and speech generator. In such a way, the erroneous analysis and uncertainty happening in the preceding stages would be recovered and determined accurately with highlevel knowledge. Moreover, instead of shallow wordlevel analysis or simply keyword or key phrase matching, a deeper analysis is performed in our system by integrating a robust parser and a semantic interpreter. The robust parser is particularly important for spontaneous speech inputs because most of the inquiry sentences/phrases are illformed. In addition, in designing a mixedinitiative dialogue system, understanding users’ inquiries is essential; however, simply | Mao Jiaju Chen Qiulin Gao Feng Guo Rong Lu Ruzhan | 2005 | Journal of Systems Engineering and Electronics2005，16，4： | 0 |
| 18 | A MALDI-MS sensing chip prepared by non-covalent assembly for quantitation of acid phosphatase显示文摘A novel sensing chip was designed for MALDI-MS quantitation of acid phosphatase(ACP).The ACP sensing chip was constructed through non-covalent interaction of streptavidin and biotin for the assembly of biotinylated peptide substrate on biotinylated polyethylene-glycol(PEG)modified indium-tin oxide(ITO)slide.In the presence of ACP,the peptide substrate was dephosphorylated under acidic condition to generate a new mass signal.The quantitative assay of ACP was achieved with the mass signal ratio of product to the sum of product and left peptide substrate.Under optimal detection conditions,the ratio was linearly correlated with the concentration of ACP in the range of 0.05–12 g/L with a detection limit(LOD)of 0.04 g/L.The designed ACP sensing chip has been used to analyze ACP in complex clinical samples,which exhibited high selectivity,good repeatability,and admirably anti-interference ability.This work further demonstrates the concept of MS sensing and the application of MALDI-MS in quantitative analysis,and provides a convenient method for the quantitation of proteases in clinical diagnosis. | Qiulin Ma Yunlong Chen Nan Feng Feng Yan Huangxian Ju | 2021 | Science China Chemistry2021，64，1： | 0 |

| 20 | Boosting the catalytic performance of Cu-SAPO-34in NO_(x) removal via hydrothermal treatment显示文摘Phosphate ions promoted Cu-SAPO-34(P-Cu-SAPO-34)were prepared using bulk CuO particles as Cu^(2+)precursor by a solid-state ion exchange technique for the selective catalytic reduction of NO_(x) with NH_3(NH_3-SCR).The effects of high temperature(H-T)hydrothermal aging on the NO_(x) removal(de-NO_(x))performance of Cu-SAPO-34 with and without phosphate ions were systematically investigated at atomic level.The results displayed that both Cu-SAPO-34 and P-Cu-SAPO-34 presented relatively poor NO_(x) removal activity with a low conversion(<30%)at 250-500℃.However,after H-T hydrothermal treatment(800℃ for 10 hr at 10%H_2O),these two samples showed significantly satisfied NO_(x) elimination performance with a quite high conversion(70%-90%)at 250-500℃.Additionally,phosphate ions decoration can further enhance the catalytic performance of Cu-SAPO-34 after hydrothermal treatment(Cu-SAPO-34H).The textural properties,morphologies,structural feature,acidity,redox characteristic,and surface-active species of the fresh and hydrothermally aged samples were analyzed using various characterization methods.The systematical characterization results revealed that increases of 28%of the isolated Cu^(2+)active species(Cu^(2+)-2Z,Cu(OH)^(+)-Z)mainly from bulk CuO and 50%of the Bronsted acid sites,the high dispersion of isolated Cu^(2+)active component as well as the Bronsted acid sites were mainly responsible for the accepted catalytic activity of these two hydrothermally aged samples,especially for P-Cu-SAPO-34H. | Xiaoyan Tian Huimin Wang Siyuan Xu Lianyun Gao Jinyan Cao Jianjun Chen Qiulin Zhang Ping Ning Jiming Hao | 2024 | Journal of Environmental Sciences2024，，1： | 0 |
