| 1 | 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 |
| 2 | Influence of sunlight on the proliferation of cyanobacterial blooms and its potential applications in Lake Taihu, China显示文摘To learn the relationship between sunlight intensity and cyanobacterial proliferations for the further control of the heavy blooms, enclosure experiment were conducted in Meiliang Bay, Lake Taihu by regulating the natural light intensities with different shading ratio(0%(full sunlight), 10%, 25%, 50% and 75% of original natural sunlight intensities) from September to November in 2010. The results indicated that phytoplankton biomass(mean) decreased significantly when the shading ratios reached 50% or more. Higher shading ratios(e.g. 75%) were very efficient in controlling the average and total cyanobacterial bloom biomass, while 50% shading ratio was proven very effective either in controlling the peak value of phytoplankton biomass or postponing the occurrence of cyanobacterial blooms in Lake Taihu. In addition, phytoplankton composition and photosynthesis efficiency were also affected by altering the shading ratios, and in turn, they might also act on phytoplankton growth. Based on the results from the present study, intermediate shading strategies such as regulation of water level or turbidity through the hydrology regulations would probably be an effective and efficient method in controlling cyanobacterial blooms in large and shallow lakes. | Qichao Zhou Wei Chen Kun Shan Lingling Zheng Lirong Song | 2014 | Journal of Environmental Sciences2014，26，3： | 6 |
| 3 | Effects of inorganic arsenic on growth and microcystin production of a Microcystis strain isolated from an algal bloom in Dianchi Lake,China显示文摘Our previous data have shown that inorganic arsenic concentrations were high in Dianchi Lake,China,where Microcystis blooms often occur.To explore the relationship between arsenic and the growth of Microcystis,the effects of arsenite[As(III)]and arsenate[As(V)]on the growth and toxin production of M.aeruginosa strain FACHB 905 were tested.Results showed that M.aeruginosa FACHB 905 was tolerant to inorganic arsenic and its growth was not inhibited when the concentration of As(III)was below 10-5 mol L-1 or that of As(V)below 10-3 mol L-1.Total microcystin production was stimulated in the presence of 10-7 mol L-1 As(III)and the response of this M.aeruginosa strain to As(III)seemed to be a typical inverted U-shaped hormesis.The content increase of microcystin-LR per cell indicated that the toxicity was enhanced as M.aeruginosa FACHB 905 was exposed to As(V).Considering the relatively high concentration of inorganic arsenic in Dianchi Lake(139μg L-1 in epilimnetic water),the origin of the M.aeruginosa strain,inorganic arsenic favors survival of M.aeruginosa FACHB 905 and may stimulate its microcystin production and cellular toxicity. | GONG Yan AO HongYi LIU BiBo WEN Sheng WANG Zhi HU DingJing ZHANG XingZhong SONG LiRong LIU JianTong | 2011 | Chinese Science Bulletin2011，56，22： | 6 |
| 4 | A flow cytometer based protocol for quantitative analysis of bloom-forming cyanobacteria(Microcystis) in lake sediments显示文摘A quantitative protocol for the rapid analysis of Microcystis cells and colonies in lake sediment was developed using a modified flow cytometer,the CytoSense.For cell enumeration,diluted sediment samples containing Microcystis were processed with sonication to disintegrate colonies into single cells.An optimized procedure suggested that 5 mg dw(dry weight)/mL dilution combined with 200 W × 2 min sonication yielded the highest counting efficiency.Under the optimized determination conditions,the quantification limit of this protocol was 3.3×10 4 cells/g dw.For colony analysis,Microcystis were isolated from the sediment by filtration.Colony lengths measured by flow cytometry were similar to those measured by microscopy for the size range of one single cell to almost 400 μm in length.Moreover,the relationship between colony size and cell number was determined for three Microcystis species,including Microcystis flos-aquae,M.aeruginosa and M.wessenbergii.Regression formulas were used to calculate the cell numbers in differentsized colonies.The developed protocol was applied to field sediment samples from Lake Taihu.The results indicated the potential and applicability of flow cytometry as a tool for the rapid analysis of benthic Microcystis.This study provided a new capability for the high frequency monitoring of benthic overwintering and population dynamics of this bloom-forming cyanobacterium. | Quan Zhou Wei Chen Huiyong Zhang Liang Peng Liming Liu Zhiguo Han Neng Wan Lin Li Lirong Song | 2012 | Journal of Environmental Sciences2012，24，9： | 5 |
| 5 | Tuning the selectivity of photoreduction of CO2 to syngas over Pd/layered double hydroxide nanosheets under visible light up to 600 nm显示文摘Photocatalytic reduction of CO2 with H2 O to syngas is an effective way for producing high value-added chemical feedstocks such as methanol and light olefins in industry.Nevertheless,the precise control of CO/H2 ratio from photocatalytic CO2 reduction reaction still poses a great challenge for the further application.Herein,we prepared a series of highly efficient heterostructure based on highly dispersed palladium supported on ultrathin Co Al-layered double hydroxide(LDH).In conjunction with a Ru-complex sensitizer,the molar ratios of CO/H2 can be tuned from 1:0.74 to 1:3 under visible-light irradiation(λ>400 nm).More interestingly,the syngas can be obtained under light irradiation atλ>600 nm.Structure characterization and density functional theory calculations revealed that the remarkable catalytic activity can be due to the supported palladium,which improved the charge transfer efficiency.Meanwhile,more H atoms were used to generate H2 on the supported palladium for further tunable CO/H2 ratio.This work demonstrates a new strategy for harnessing abundant solar-energy to produce syngas from a CO2 feedstock. | Xian Wang Zelin Wang Ya Bai Ling Tan Yanqi Xu Xiaojie Hao Jikang Wang Abdul Hanif Mahadi Yufei Zhao Lirong Zheng Yu-Fei Song | 2020 | Journal of Energy Chemistry2020，29，7： | 5 |
| 6 | Photocatalytic properties of hierarchical BiOXs obtained via an ethanol-assisted solvothermal process显示文摘In this study, bismuth oxyhalide(Bi OXs(X_Cl, Br, I)) semiconductors were prepared by a simple solvothermal method, with ethanol serving as solvent and a series of tetrabutylammonium halide surfactants as halogen sources. Under identical synthetic conditions, Bi OBr was more readily constructed into regular flower-like hierarchical architectures. The photocatalytic properties of the materials were studied by monitoring the degradation of rhodamine B(Rh B),with visible light absorption, and colorless salicylic acid(SA). It was found that both Rh B and SA were rapidly degraded on the surface of Bi OBr. Bi OCl was rather active for the degradation of Rh B,but ineffective toward the degradation of SA. However, neither Rh B nor SA could be degraded effectively in the case of Bi OI. Further experiments such as UV–visible spectroscopy and detection of U OH and O2 Uradicals suggest that the electronic structure of the Bi OX photocatalysts is responsible for the difference in their activities. | Manke Jia Xiaolong Hu Shulian Wang Yingping Huang Lirong Song | 2015 | Journal of Environmental Sciences2015，27，9： | 5 |
| 7 | Insights into the design of thermoelectric Mg_(3)Sb_(2) and its analogs by combining theory and experiment显示文摘Over the past two decades,we have witnessed a strong interest in developing Mg3Sb2 and related CaAl2Si2-type materials for lowand intermediate-temperature thermoelectric applications.In this review,we discuss how computations coupled with experiments provide insights for understanding chemical bonding,electronic transport,point defects,thermal transport,and transport anisotropy in these materials.Based on the underlying insights,we examine design strategies to guide the further optimization and development of thermoelectric Mg3Sb2-based materials and their analogs.We begin with a general introduction of the Zintl concept for understanding bonding and properties and then reveal the breakdown of this concept in AMg2X2 with a nearly isotropic three-dimensional chemical bonding network.For electronic transport,we start from a simple yet powerful atomic orbital scheme of tuning orbital degeneracy for optimizing p-type electrical properties,then discuss the complex Fermi surface aided by high valley degeneracy,carrier pocket anisotropy,and light conductivity effective mass responsible for the exceptional n-type transport properties,and finally address the defect-controlled carrier density in relation to the electronegativity and bonding character.Regarding thermal transport,we discuss the insight into the origin of the intrinsically low lattice thermal conductivity in Mg3Sb2.Furthermore,the anisotropies in electronic and thermal transport properties are discussed in relation to crystal orbitals and chemical bonding.Finally,some specific challenges and perspectives on how to make further developments are presented. | Jiawei Zhang Lirong Song Bo Brummerstedt Iversen | 2019 | npj Computational Materials2019，，1： | 4 |
| 8 | Quantitative assessment of toxic and nontoxic Microcystis colonies in natural environments using fluorescence in situ hybridization and flow cytometry显示文摘Toxic cyanobacterial blooms constitute a threat to human safety because Microcystis sp. releases microcystins during growth, and particularly during cell death. Therefore, analysis of toxic and nontoxic Microcystis in natural communities is required in order to assess and predict bloom dynamics and toxin production by these organisms. In this study, an analysis combining fluorescence in situ hybridization (FISH) with flow cytometry (FCM) was used to discriminate between toxic and nontoxic Microcystis and also to quantify the percentage of toxic Microcystis present in blooms. The results demonstrate that the combination of FISH and flow cytometry is a useful approach for studying the ecology of Microcystis toxin production and for providing an early warning for toxic Microcystis blooms. | GAN NanQin, HUANG Qun, ZHENG LingLing & SONG LiRong State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2010 | Science China(Life Sciences)2010，53，8： | 3 |
| 9 | Uniform single atomic Cu_(1)-C_(4)sites anchored in graphdiyne for hydroxylation of benzene to phenol显示文摘For single-atom catalysts(SACs),the catalyst supports are not only anchors for single atoms,but also modulators for geometric and electronic structures,which determine their catalytic performance.Selecting an appropriate support to prepare SACs with uniform coordination environments is critical for achieving optimal performance and clarifying the relationship between the structure and the property of SACs.Approaching such a goal is still a significant challenge.Taking advantage of the strong d-πinteraction between Cu atoms and diacetylenic in a graphdiyne(GDY)support,we present an efficient and simple strategy for fabricating Cu single atoms anchored on GDY(Cu_(1)/GDY)with uniform Cu_(1)-C_(4)single sites under mild conditions.The Cu atomic structure was confirmed by combining synchrotron radiation X-ray absorption spectroscopy,X-ray photoele ctron spectroscopy and density functional theory(DFT)calculations.The as-prepared Cu1/GDY exhibits much higher activity than state-of-the-art SACs in direct benzene oxidation to phenol with H_(2)O_(2)reaction,with turnover frequency values of 251 h^(-1)at room temperature and 1889 h^(-1)at 60℃,respectively.Furthermore,even with a high benzene conversion of86%,high phenol sele ctivity(96%)is maintaine d,which can be ascribed to the hydrophobic and oleophyllic surface nature of Cu1/GDY for benzene adsorption and phenol desorption.Both experiments and DFT calculations indicate that Cu_(1)-C_(4)single sites are more effective at activating H_(2)O_(2)to form Cu=O bonds,which are important active intermediates for benzene oxidation to phenol. | Jia Yu Changyan Cao Hongqiang Jin Weiming Chen Qikai Shen Peipei Li Lirong Zheng Feng He Weiguo Song Yuliang Li | 2022 | National Science Review2022，9，9： | 3 |
| 10 | An inducible CO_2 concentrating mechanism in cyanobacterium Anabaena sp. strain PCC7120显示文摘In order to define its characteristics of the photosynthetic utilization of CO2 and HCO3-when the ambient inorganic carbon changed, HCG (High-CO2-Growing Cells) of cyanobacteri-um Anabaena sp. strain PCC7120 were prepared. The growth rate of HCG was higher than that of LCG (low-CO2-growing cells, i.e. air-growing cells). When the HCG cells were transferred from 5% CO2 to air levels of CO2, a series of changes took place: its carbonic | WU Tianfu, SONG Lirong and LIU YongdingInstitute of Hydrobiology , Chinese Academy of Sciences , Wuhan 430072 , China Corresponding author | 1999 | Chinese Science Bulletin1999，44，23： | 3 |
| 11 | Improving photosynthesis of microalgae by changing the ratio of light-harvesting pigments显示文摘Changing the ratio of light-harvesting pigments was regarded as an efficient way to improve the photosyn-thesis rate in microalgae, but the underlying mechanism is still unclear. In the present study, a mutant of Anabeana simensis (called SP) was selected from retrieved satellite cul-tures. Several parameters related with photosynthesis, such as the growth, photosynthesis rate, the content of photosyn-thetic pigment, low temperature fluorescence spectrum (77K) and electron transport rate, were compared with those of the wild type. It was found that the change in the ratio of light-harvesting pigments in the mutant led to more efficient light energy transfer and usage in mutant than in the wild type. This may be the reason why the mutant had higher photosynthesis and growth rates. | WANG Gaohong CHEN Lanzhou LI Genbao LI Dunhai HU Chunxiang CHEN Haofeng LIU Yongding SONG Lirong | 2005 | Chinese Science Bulletin2005，50，15： | 3 |

| 13 | Effects of complement inhibition on the ABC phenomenon in rats显示文摘Researchers reported that intravenously injected PEGylated colloidal drug carriers lose their long-circulating characteristic and accumulated extensively in liver when they are administrated twice in the same animal with certain intervals. This phenomenon was referred to as the 'accelerated blood clearance(ABC) phenomenon'. Some former studies had found that complement-mediated phagocytosis, activated by antigen–antibody complex, was responsible for inducing the phenomenon. According to the theory, we have used cobra venom factor to deplete complement in vivo and to investigate the effect of complement inhibition on the ABC phenomenon. Rats were administered by injection of cobra venom factor solution to build up the model of complement exhaustion/inhibition, and the effect of the inhibition of complement on ABC phenomenon was carried out. It seemed that inhibition of complement didn’t affect the pharmacokinetic of the first infection. By contrast, in rats of which complement had been depleted, the second dose of PEGylated nanoemulsions showed enhanced circulation time compared with normal rats in a complement inhibition-independent manner, but the ABC phenomenon was not completely eliminated. It indicated that complement inhibition could certainly weaken the accelerated clearance;meanwhile, there were other factors causing the ABC effect.These findings provide novel insights into the attenuating of ABC phenomenon and lay foundation for further study of immune mechanism. | Lirong Wang Yuqing Su Xuling Wang Kaifan Liang Mengyang Liu Wenya Tang Yanzhi Song Xinrong Liu Yihui Deng | 2017 | Asian Journal of Pharmaceutical Sciences2017，12，3： | 2 |

| 15 | Submerged vegetation removal promotes shift of dominant phytoplankton functional groups in a eutrophic lake显示文摘Historical data indicate that the dominance of submerged plants in Dianchi Lake in the 1960 s was characterized by low algal density with dominance of non-toxic group J(Scenedesmus,Pediastrum,etc.). The removal of submerged plants,which began in the 1970 s,resulted in the expansion of bloom-forming Microcystis(group M). Laboratory experiments suggested that Microcystis aeruginosa was inclined to grow and develop at elevated temperatures. The growth of Scenedesmus obliquus was slower than that of co-cultivated M. aeruginosa in the absence of Ceratophyllum demersum,especially at higher temperatures. The existence of submerged plant C. demersum could inhibit the growth of the harmful algae M. aeruginosa and this inhibitory effect by C. demersum was enhanced with an increase in temperature. Instead,with C. demersum,the growth of S. obliquus was not inhibited,but the co-cultivated M. aeruginosa was eliminated in a short time. Combined with the historical data and laboratory experiments,it was indicated that the submerged plants might play important roles in the dominance of the non-toxic group J in the historical succession. Consequently,the introduction of the submerged plant such as C. demersum might alter the dominant phytoplankton functional groups from M to J and benefit the restoration of the eutrophic lake. | Jing Dong Kai Yang Shuangshuang Li Genbao Li Lirong Song | 2014 | Journal of Environmental Sciences2014，26，8： | 2 |

| 18 | Insights into the phenomenon of an explosive growth and sharp decline in haze:A case study in Beijing显示文摘A severe haze episode occurred in winter in the North China Plain(NCP),and the phenomenon of an explosive growth and sharp decline in PM2.5(particulate matter with an aerodynamic diameter equal to or less than 2.5μm)concentration was observed.To study the systematic causes for this phenomenon,comprehensive observations were conducted in Beijing from November 26 to December 2,2015;during this period,meteorological parameters,LIDAR data,and the chemical compositions of aerosols were determined.The haze episode was characterized by rapidly varying PM2.5 concentration,and the highest PM2.5 concentration reached 667μg/m3.During the haze episode,the NCP was dominated by a weak high-pressure system and continuously low PBL(planetary boundary layer)heights,which are unfavorable conditions for the diffusion of pollutants.The large increases in the concentrations of SNA(SO42-,NO3-and NH4+)during the haze implied that the formation of SNA was the largest contribution.Water vapor also played a vital role in the formation of haze by promoting the chemical transformation of secondary pollutants,which led to higher PM2.5 concentrations.The spatial distributions of PM2.5 in Beijing at different times and the backward trajectories of the air masses also indicated that pollutants from surrounding provinces in particular,contributed to the higher PM2.5concentration. | Wenguang Li Xingang Liu Yuanhang Zhang Qinwen Tan Miao Feng Mengdi Song Lirong Hui Yu Qu Junling An Haokai Gao | 2019 | Journal of Environmental Sciences2019，31，10： | 1 |

| 20 | Jigsaw-like mini-pillar platform for multi-mode biosensing显示文摘The multiple sensing provides booming options to eliminate interference and ensure the accuracy of detection by mutually coupling and validating multiple data sets.Here,we integrate the jigsaw-like multifunctional mini-pillar platform to perform multi-mode(electrochemical,fluorescence,surface-enhanced Raman scattering(SERS)and colorimetric)sensing in individual microdroplets.Each mini-pillar connector can parallelize together by specific concave-convex interface to form integrated jigsaw-like platform for multi-mode sensing,and each specific mini-pillar can be modified into the individual sensing unit to read the prescribed signals.We successfully implemented electrochemical,fluorescence,SERS and colorimetric detection by multiple signals coupling to reduce the false positive analysis.Such platform brings a promising clue of in-situ analysis and point-of-care testing for disease diagnosis and health monitoring. | Yongchao Song Dongdong Wang Zehua Li Lirong Wang Chuan Fan Xuecheng He Tailin Xu Xueji Zhang | 2022 | Chinese Chemical Letters2022，33，8： | 1 |
