| 1 | The Reference Genome of Tea Plant and Resequencing of 81 Diverse Accessions Provide Insights into Its Genome Evolution and Adaptation显示文摘Tea plant is an important economic crop,which is used to produce the world's oldest and most widely consumed tea beverages.Here,we present a high-quality reference genome assembly of the tea plant(Camellia sinensis var.sinensis)consisting of 15 pseudo-chromosomes.LTR retrotransposons(LTR-RTs)account for 70.38%of the genome,and we present evidence that LTR-RTS play critical roles in genome size expansion and the transcriptional diversification of tea plant genes through preferential insertion in promoter regions and introns.Genes,particularly those coding for terpene biosynthesis pro-teins,associated with tea aroma and stress resistance were significantly amplified through recent tandem duplications and exist as gene clusters in tea plant genome.Phylogenetic analysis of the sequences of 81 tea plant accessions with diverse origins revealed three well-differentiated tea plant populations,support-ing the proposition for the southwest origin of the Chinese cultivated tea plant and its later spread to western Asia through introduction.Domestication and modern breeding left significant signatures on hundreds of genes in the tea plant genome,particularly those associated with tea quality and stress resis-tance.The genomic sequences of the reported reference and resequenced tea plant accessions provide valuable resources for future functional genomics study and molecular breeding of improved cul-tivars of tea plants. | Enhua Xia Wei Tong Yan Hou Yanlin An Linbo Chen Qiong Wu Yunlong Liu Jie Yu Fangdong Li Ruopei Li Penghui Li Huijuan Zhao Ruoheng Ge Jin Huang Ali Inayat Mallano Yanrui Zhang Shengrui Liu Weiwei Deng Chuankui Song Zhaoliang Zhang Jian Zhao Shu Wei Zhengzhu Zhang Tao Xia Chaoling Wei Xiaochun Wan | 2020 | Molecular Plant2020，13，7： | 51 |
| 2 | Adsorption of heavy metal ions from aqueous solution by carboxylated cellulose nanocrystals显示文摘A novel nanoadsorbent for the removal of heavy metal ions is reported.Cotton was first hydrolyzed to obtain cellulose nanocrystals(CNCs).CNCs were then chemically modified with succinic anhydride to obtain SCNCs.The sodic nanoadsorbent(NaSCNCs) was further prepared by treatment of SCNCs with saturated NaHCO 3 aqueous solution.Batch experiments were carried out with SCNCs and NaSCNCs for the removal of Pb 2+ and Cd 2+.The effects of contact time,pH,initial adsorption concentration,coexisting ions and the regeneration performance were investigated.Kinetic studies showed that the adsorption equilibrium time of Pb 2+ and Cd 2+ was reached within 150 min on SCNCs and 5 min on NaSCNCs.The adsorption capacities of Pb 2+ and Cd 2+ on SCNCs and NaSCNCs increased with increasing pH.The adsorption isotherm was well fitted by the Langmuir model.The maximum adsorption capacities of SCNCs and NaSCNCs for Pb 2+ and Cd 2+ were 367.6 mg/g,259.7 mg/g and 465.1 mg/g,344.8 mg/g,respectively.SCNCs and NaSCNCs showed high selectivity and interference resistance from coexisting ions for the adsorption of Pb 2+.NaSCNCs could be efficiently regenerated with a mild saturated NaCl solution with no loss of capacity after two recycles.The adsorption mechanisms of SCNCs and NaSCNCs were discussed. | Xiaolin Yu Shengrui Tong Maofa Ge Lingyan Wu Junchao Zuo Changyan Cao Weiguo Song | 2013 | Journal of Environmental Sciences2013，25，5： | 29 |
| 3 | Heterogeneous uptake of nitrogen dioxide on Chinese mineral dust显示文摘Mineral dust is one of the major aerosols in the atmosphere.To assess its impact on trace atmospheric gases,in this work we present a laboratory study of the effect of temperature on the heterogeneous reaction of NO_2 on the surface of ambient Chinese dust over the temperature range from 258 to 313 K.The results suggest that nitrogen dioxide could mainly be adsorbed on these types of Chinese mineral dust reversibly with little temperature dependence.Similar to a previous study on NO_2 uptake on mineral aerosols,the uptake coefficients are mainly on the order of 10^(-6) for the Chinese dust,when BET areas are taken into account.HONO was observed as a product,and its formation and decomposition on Chinese mineral dust during the uptake processes were also studied.The complete dataset from this study was compiled with previous literature determinations.Atmospheric implications of the heterogeneous reaction between NO_2 and mineral dust are also discussed,in an effort to understand this important heterogeneous process. | Li Zhou Weigang Wang Siqi Hou Shengrui Tong Maofa Ge | 2015 | Journal of Environmental Sciences2015，27，12： | 6 |
| 4 | Light absorption properties and potential sources of brown carbon in Fenwei Plain during winter 2018–2019显示文摘A distinctive kind of organic carbon aerosol that could absorb ultraviolet-visible radiation is called brown carbon(Br C),which has an important positive influence on radiative budget and climate change.In this work,we reported the absorption properties and potential source of Br C based on a seven-wavelength aethalometer in the winter of 2018–2019 at an urban site of Sanmenxia in Fenwei Plain in central China.Specifically,the mean value of Br C absorption coefficient was 59.6±36.0 Mm^(-1) at 370 nm and contributed 37.7%to total absorption,which made a significant impact on visibility and regional environment.Absorption coefficients of Br C showed double-peak pattern,and Br C had shown small fluctuations under haze days compared with clean days.As for the sources of Br C,Br C absorption coefficients expressed strong correlations with element carbon aerosols and primary organic carbon aerosols,indicating that most of Br C originated from primary emissions.The linear correlations between trace metal elements(K,As,Fe,Mn,Zn,and Pb)and Br C absorption coefficients further referred that the major sources of Br C were primary emissions,like coal burning,biomass burning,and vehicle emissions.The moderate relationship between Br C absorption coefficients and secondary organic aerosols suggested that secondary production of Br C also played an important role.The 120 hr backward air mass trajectories analysis and concentration-weighted trajectories analysis were also used to investigate potential sources of Br C in and around this area,which inferred most parts of Br C were derived from local emissions. | Wenyu Zhang Weigang Wang Jie Li Shuangliang Ma Chaofan Lian Kun Li Bo Shi Mingyuan Liu Yanyu Li QingQing Wang Yele Sun Shengrui Tong Maofa Ge | 2021 | Journal of Environmental Sciences2021，33，4： | 6 |
| 5 | Review of Chinese atmospheric science research over the past 70 years: Atmospheric physics and atmospheric environment显示文摘Since the founding of the People’s Republic of China 70 years ago,the subject of atmospheric physics and atmospheric environment has developed rapidly in China,providing important support for the development of atmospheric science and guarantee for the development of national economy.In this paper,the general advancement of atmospheric physics and atmospheric environment in last 70 years was described.The main research progress of atmospheric physics and atmospheric environment in the past 40 years of reform and opening-up was reviewed,the outstanding research achievements since the 21 st century were summarized,the major problems and challenges are pointed out,and the key directions and suggestions for future development are put forward. | Tijian WANG Taichang GAO Hongsheng ZHANG Maofa GE Hengchi LEI Peichang ZHANG Peng ZHANG Chunsong LU Chao LIU Hua ZHANG Qiang ZHANG Hong LIAO Haidong KAN Zhaozhong FENG Yijun ZHANG Xiushu QIE Xuhui CAI Mengmeng LI Lei LIU Shengrui TONG | 2019 | Science China Earth Sciences2019，62，12： | 5 |
| 6 | Kinetic study of the gas-phase reaction of O3 with three unsaturated alcohols显示文摘Rate constants for the reactions of ozone with 1-octen-3-ol, 1-nonen-3-ol and 1-nonen-4-ol have been determined at 298 ± 1 K and atmospheric pressure for the first time. The experiments were performed in a 100-L FEP Teflon film bag using absolute rate method; the rate constants were(1.91 ± 0.19) × 10^(-17),(1.89 ± 0.20) × 10^(-17), and(0.83 ± 0.08) × 10^(-17)cm^3/(molecule·sec) for 1-octen-3-ol, 1-nonen-3-ol, and 1-nonen-4-ol, respectively. The rate constants have been compared with those of unsaturated alcohols structural homologs, and used to estimate the reaction reactivity. The electronegativity of carbon–carbon double bond was calculated by atomic charges analysis. The calculated results show that the electronic effect of the lone pair electrons of hydroxyl oxygen is the main cause of the difference in rate coefficient. According to the obtained rate constants, the atmospheric lifetimes of studied unsaturated alcohols were also estimated, which indicates that the reaction with ozone is an important loss pathway in the atmosphere, especially in polluted areas. | Weiran Li Yi Chen Shengrui Tong Yucong Guo Yunhong Zhang Maofa Ge | 2018 | Journal of Environmental Sciences2018，30，9： | 4 |
| 7 | Comparisons of measured nitrous acid(HONO) concentrations in a pollution period at urban and suburban Beijing, in autumn of 2014显示文摘To study the HONO formation mechanisms during a pollution period, a continuous measurement was performed in both urban and suburban aeras of Beijing. During this period, the PM2.5 concentrations increased to 201 and 137 ?g/m3 in urban and suburban areas, respectively. The concentrations of HONO, CO, SO2, O3, NO, NO2, NOx were 1.45 ppbv, 0.61 ppmv, 8.7 ppbv, 4.3 ppbv, 44.4 ppbv, 37.4 ppbv, 79.4 ppbv and 0.72 ppbv, 1.00 ppmv, 1.2 ppbv, 7.9 ppbv, 3.7 ppbv, 8.2 ppbv, 11.9 ppbv, in urban and suburban areas, respectively. To compare possible pathways of HONO formation in both sites, the contributions of direct emissions, heterogeneous formations, and homogeneous productions were studied. HONO/NO2 ratios in the two sites indicated that heterogeneous reactions of NO2 were more efficient in suburban areas. And in both urban and suburban areas, the increase of PM2.5 concentrations and RH would promote the conversion efficiency in RH that ranged from 0% to 85%. However, when RH was above 85%, the HONO formation slowed down. Moreover, the study of direct emissions and homogeneous reactions showed that they contributed to a majority of HONO increase in urban areas than the 20% contributions in suburban areas. It implied that the high NOx concentrations and NO concentrations in urban areas or in pollution periods would make direct emissions and homogeneous reactions become dominant in HONO formations. | Shengrui Tong Siqi Hou Ying Zhang Biwu Chu Yongchun Liu Hong He Pusheng Zhao Maofa Ge | 2015 | Science China Chemistry2015，58，9： | 3 |
| 8 | Atmospheric oxidizing capacity in autumn Beijing:Analysis of the O_(3) and PM_(2.5) episodes based on observation-based model显示文摘Atmospheric oxidizing capacity(AOC)is the fundamental driving factors of chemistry process(e.g.,the formation of ozone(O_(3))and secondary organic aerosols(SOA))in the troposphere.However,accurate quantification of AOC still remains uncertainty.In this study,a comprehensive field campaign was conducted during autumn 2019 in downtown of Beijing,where O_(3) and PM_(2.5) episodes had been experienced successively.The observation-based model(OBM)is used to quantify the AOC at O_(3) and PM_(2.5) episodes.The strong intensity of AOC is found at O_(3) and PM2.5 episodes,and hydroxyl radical(OH)is the dominating daytime oxidant for both episodes.The photolysis of O_(3) is main source of OH at O_(3) episode;the photolysis of nitrous acid(HONO)and formaldehyde(HCHO)plays important role in OH formation at PM_(2.5) episode.The radicals loss routines vary according to precursor pollutants,resulting in different types of air pollution.O_(3) budgets and sensitivity analysis indicates that O_(3) production is transition regime(both VOC and NOx-limited)at O3 episode.The heterogeneous reaction of hydroperoxy radicals(HO_(2))on aerosol surfaces has significant influence on OH and O_(3) production rates.The HO_(2) uptake coefficient(γHO_(2))is the determining factor and required accurate measurement in real atmospheric environment.Our findings could provide the important bases for coordinated control of PM_(2.5) and O_(3) pollution. | Chenhui Jia Shengrui Tong Xinran Zhang Fangjie Li Wenqian Zhang Weiran Li ZhenWang Gen Zhang Guiqian Tang Zirui Liu Maofa Ge | 2023 | Journal of Environmental Sciences2023，，2： | 2 |
| 9 | RO_(x) Budgets and O_(3) Formation during Summertime at Xianghe Suburban Site in the North China Plain显示文摘Photochemical smog characterized by high concentrations of ozone(O_(3)) is a serious air pollution issue in the North China Plain(NCP)region,especially in summer and autumn.For this study,measurements of O_(3),nitrogen oxides(NO_(x)),volatile organic compounds(VOCs),carbon monoxide(CO),nitrous acid(HONO),and a number of key physical parameters were taken at a suburban site,Xianghe,in the NCP region during the summer of 2018 in order to better understand the photochemical processes leading to O_(3)formation and find an optimal way to control O_(3)pollution.Here,the radical chemistry and O_(3)photochemical budget based on measurement data from 1−23 July using a chemical box model is investigated.The daytime(0600−1800 LST)average production rate of the primary radicals referred to as RO_(x)(OH+HO2+RO2)is 3.9 ppbv h−1.HONO photolysis is the largest primary RO_(x)source(41%).Reaction of NO2+OH is the largest contributor to radical termination(41%),followed by reactions of RO2+NO2(26%).The average diurnal maximum O_(3)production and loss rates are 32.9 ppbv h−1 and 4.3 ppbv h−1,respectively.Sensitivity tests without the HONO constraint lead to decreases in daytime average primary RO_(x)production by 55%and O_(3)photochemical production by 42%,highlighting the importance of accurate HONO measurements when quantifying the RO_(x)budget and O_(3)photochemical production.Considering heterogeneous reactions of trace gases and radicals on aerosols,aerosol uptake of HO2 contributes 11%to RO_(x)sink,and the daytime average O_(3)photochemical production decreases by 14%.The O_(3)-NO_(x)-VOCs sensitivity shows that the O_(3)production at Xianghe during the investigation period is mainly controlled by VOCs. | Min XUE Jianzhong MA Guiqian TANG Shengrui TONG Bo HU Xinran ZHANG Xinru LI Yuesi WANG | 2021 | Advances in Atmospheric Sciences2021，38，7： | 2 |
| 10 | Water uptake of multicomponent organic mixtures and their influence on hygroscopicity of inorganic salts显示文摘The hygroscopic behaviors of atmospherically relevant multicomponent water soluble organic compounds(WSOCs) and their effects on ammonium sulfate(AS) and sodium chloride were investigated using a hygroscopicity tandem differential mobility analyzer(HTDMA) in the relative humidity(RH) range of 5%–90%. The measured hygroscopic growth was compared with predictions from the Extended-Aerosol Inorganics Model(E-AIM) and Zdanovskii–Stokes–Robinson(ZSR) method. The equal mass multicomponent WSOCs mixture containing levoglucosan, succinic acid, phthalic acid and humic acid showed gradual water uptake without obvious phase change over the whole RH range. It was found that the organic content played an important role in the water uptake of mixed particles.When organic content was dominant in the mixture(75%), the measured hygroscopic growth was higher than predictions from the E-AIM or ZSR relation, especially under high RH conditions. For mass fractions of organics not larger than 50%, the hygroscopic growth of mixtures was in good agreement with model predictions. The influence of interactions between inorganic and organic components on the hygroscopicity of mixed particles was related to the salt type and organic content. These results could contribute to understanding of the hygroscopic behaviors of multicomponent aerosol particles. | Yuanyuan Wang Bo Jing Yucong Guo Junling Li Shengrui Tong Yunhong Zhang Maofa Ge | 2016 | Journal of Environmental Sciences2016，28，7： | 1 |
| 11 | Heterogeneous chemistry of trace atmospheric gases on atmospheric aerosols:An overview显示文摘Due to altering the budget of important trace gases and changing the composition of atmospheric aerosols,heterogeneous reactions between trace gases and liquid/solid aerosols have become an important subject of atmospheric science in recent years.However,the kinetics and mechanism of these reactions have not been well-understood yet.In recent years,we have established an integrated method to study a series of atmospheric heterogeneous reactions under control atmospheric conditions.Using on-line techniques,such as Diffuse Reflectance Infrared Fourier Transform spectroscopy,Raman microspectrometry and Knudsen cell,the heterogeneous reactions of a series of trace gases(NO2,SO2,H2O2,DMS,C2H5 I and Monocarboxylic acids)on mineral oxides and black carbon were investigated.The uptake coefficients and mechanisms at different atmospheric conditions(temperature,relative humidity and reactant concentration)were obtained.In addition,a home-made equipment named rotated wetted-wall reactor was designed for the in situinvestigations of the uptake of volatile organic compounds into the H2SO4 solution and H2SO4/H2O2 mixed solution.In this review,we present the main results obtained in our laboratory studies and propose some challenges that still exist in the heterogeneous reaction studies. | GE MaoFa WU LingYan TONG ShengRui LIU QiFan WANG WeiGang | 2015 | Science Foundation in China2015，23，3： | 1 |
| 12 | Reaction mechanism and kinetics of Criegee intermediate and hydroperoxymethyl formate显示文摘The reaction mechanism and kinetics of the simplest Criegee intermediate CH_(2)OO reaction with hydroperoxymethyl formate(HPMF)was investigated at high-level quantum chemistry calculations.HPMF has two reactive functional groups,-C(O)OH and-OOH.The calculated results of thermodynamic data and rate constants indicated that the insertion reactions of CH_(2) OO with-OOH group of HPMF were more favorable than the reactions of CH_(2)OO with-C(O)OH group.The calculated overall rate constant was 2.33×10^(−13) cm^(3)/(moleculesec)at 298 K and the rate constants decreased as the temperature increased from 200 to 480 K.In addition,we also proved the polymerization reaction mechanism between CH_(2)OO and-OOH of HPMF.This theoretical study interpreted the previous experimental results,and supplied the structures of the intermediate products that couldn’t be detected during the experiment. | Meifang Chen Shengrui Tong Zhen Wang Weiran Li Yanyong Xu Sufan Wang Maofa Ge | 2021 | Journal of Environmental Sciences2021，33，7： | 0 |
| 13 | Heterogeneous uptake of gaseous hydrogen peroxide on mineral dust显示文摘The heterogeneous uptake processes of hydrogen peroxide on Arizona test dust and two types of authentic Chinese mineral dusts, i.e., Inner Mongolia desert dust and Xinjiang calciferous dust, were investigated using a Knudsen cell reactor coupled with a quadrupole mass spectrometer. The uptake coefficients were measured as a function of the initial concentration of H_2O_2 from 2.6 × 10^(11) to 1.2 × 10^(12)molecules/cm^3, and the temperature dependence of the uptake coefficients was investigated over a range from 253 to 313 K. The concentration of H_2O_2 showed little effect on the uptake coefficients of these heterogeneous processes. As a function of temperature, the initial uptake coefficients decrease with increasing temperature, whereas the steady state uptake coefficients of Arizona test dust and Inner Mongolia desert dust increase with increasing temperature. Implications for the understanding of the uptake processes onto mineral dust samples were also discussed. | Li Zhou Weigang Wang Maofa Ge Shengrui Tong | 2016 | Journal of Environmental Sciences2016，28，2： | 0 |
| 14 | Temporally Separated CO_(2) Photoreduction and H_(2)O Photooxidation over Redox-Active Conjugated Organic Polymer Films显示文摘Photocatalytic CO_(2) reduction with H_(2)O of chemicals without H2 generation is interesting but challenging.Herein,we report temporally separated CO_(2) photoreduction and H_(2)O photooxidation that are achieved over redox-active o-hydroxyazo-based conjugated organic polymer films(HAzo-COPFs),affording CO with high efficiency as the sole reduction product.HAzo-COPFs are prepared via interfacial diazo-coupling reactions of aromatic diamines and diphenols,and HAzo-COPF-1 from 4,4′-biphenol and benzidine shows the best performance with a CO generation rate of 53.6μmol g−1 h−1 under visible-light irradiation(>420 nm).Interestingly,we discovered that diphenol(DP-OH)moieties in HAzo-COPFs,serving as electron and proton donors to participate in CO_(2) photoreduction,are oxidized into quinone(DP=O)moieties,which are subsequently photoreduced to regenerate DP-OH in H_(2)O photooxidation.Consequently,CO_(2) photoreduction and H_(2)O photooxidation are temporally separated and perfectly coupled via redox transformation between DP-OH and DP=O that form in situ,affording enhanced charge carrier separation and inhibiting the hydrogen evolution reaction.This work provides new insights for the design of COP photocatalysts and artificial photosynthesis. | Guipeng Ji Yuepeng Wang Wenqiang Ye Meifang Chen Fengtao Zhang Yanfei Zhao Shengrui Tong Buxing Han Zhimin Liu | 2023 | CCS Chemistry2023，5，8： | 0 |
| 15 | Temperature dependence of the heterogeneous uptake of acrylic acid on Arizona test dust显示文摘In this study, the temperature dependence of the heterogeneous uptake of acrylic acid on Arizona test dust(ATD) has been investigated within a temperature range of 255–315 K using a Knudsen cell reactor. Combined with diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS) experiment, it was found that acrylic acid could adsorb on ATD via surface OH groups and convert to carboxylate on the particle surface. The kinetics study suggests that the initial true uptake coefficient(γt) of acrylic acid on ATD decreases from(4.02 ± 0.12) × 10^(-5) to(1.73 ± 0.05) × 10~/(-5)with a temperature increase from 255 to315 K. According to the temperature dependence of uptake coefficients, the enthalpy(ΔH obs)and entropy(ΔS obs) of uptake processes were determined to be-(9.60 ± 0.38) KJ/mol and-(121.55 ± 1.33) J·K/mol, respectively. The activation energy for desorption(E des) was calculated to be(14.57 ± 0.60) KJ/mol. These results indicated that the heterogeneous uptake of acrylic acid on ATD surface was sensitive to temperature. The heterogeneous uptake on ATD could affect the concentration of acrylic acid in the atmosphere, especially at low temperature. | Qifan Liu Yidan Wang Lingyan Wu Bo Jing Shengrui Tong Weigang Wang Maofa Ge | 2017 | Journal of Environmental Sciences2017，29，3： | 0 |
| 16 | Electron structure and substituent effects in o-,m-,p-IC_6H_4OCH_3 iodoanisoles显示文摘The electronic structures and substituent effects in o-,m-,and p-iodoanisoles have been investigated by ultraviolet photoelectron spectroscopy(UPS).The observed UPS bands were analyzed by combining empirical arguments and theoretical methods.Owing to the electron-donating nature of both iodoand methoxy substituents,the first ionization potentials of the three iodoanisoles are lower than those of iodobenzene and anisole.The presence of the two substituents in iodoanisoles leads to an electronrich structure,which might contribute to the observed high reactivity of iodoanisoles in a number of organic reactions. | TONG ShengRui,WANG WeiGang,MA ChunPing,GE MaoFa & WANG DianXun Beijing National Laboratory for Molecular Sciences(BNLMS),State Key Laboratory for Structural Chemistry of Unstable and Stable Species,Institute of Chemistry,Chinese Academy of Sciences,Beijing 100190,China | 2009 | Science China Chemistry2009，52，11： | 0 |
| 17 | Photoelectron spectroscopy of terpenoids and prediction of their rate constants in atmospheric oxidation reactions显示文摘The electronic structures of six mono-terpenoids and two of their oxygenated derivatives were studied by He I photoelectron spectroscopy(PES).The observed bands were interpreted on the basis of empirical arguments and theoretical calculations.The first vertical ionization potentials for β-pinene,α-terpinene,terpinolene,γ-terpinene,limonene,myrcene,citral,and terpinene-4-ol were determined to be 8.73,7.57,8.26,8.30,8.53,8.68,8.71,and 8.77 eV,respectively.Most of these values have not been determined by PES before.The correlations of the first vertical ionization potentials of these compounds to the natural logarithms of rate constants for their reactions with the radicals OH,NO3,and O3 were determined.The correlation coefficients for their reactions with OH,NO3,and O3 were 0.97,0.91,and 0.95,respectively.This method is a powerful technique for predicting the rate constants for the atmospheric oxidation reactions of terpenoids. | WANG XiaoPeng TONG ShengRui GE MaoFa WANG WeiGang WANG DianXun | 2010 | Chinese Science Bulletin2010，55，35： | 0 |
