| 2 | Geographical characteristics of China’s wetlands derived from remotely sensed data显示文摘In this paper, we report the first wetland mapping of the entire China using Landsat enhanced thematic mapper plus (ETM+) data. These data were obtained from the Global Land Cover Facility at the University of Maryland spanning from 1999 to 2002. A total of 597 scenes of Landsat images were georeferenced and mosaiced. Manual image interpretation of satellite images was aided with elevation data, soil data, land cover/land use data and Google Earth. The minimum mapping unit is 10 pixel × 10 pixel, equivalent to 9 ha. The aim of our first round of mapping was only targeted at the boundary delineation of any type of wetland except those wetlands that are under agricultural use (i.e., paddy fields), which has already been well mapped by others. Our interpretation results indicate that a total of 359478 km2 of wetlands are of non-agricultural use. Among our preliminarily mapped wetland, 339353 km2 are inland wetland, 2786 km2 are non-agricultural artificial wetland, and 17609 km2 are coastal wetland. Because low-tide is rarely captured in satellite images, an under-estimation of coastal wetland is inevitable. We conducted some statistics based on our mapped wetlands and compared them with those previously obtained from a number of sources including a land cover/land use map made with satellite images during the late 1990s and early 2000s, a marshland map developed in approximately the same period, survey data of coastal wetland in early 1980s, and area data for approximately 400 larger patches of marshland in China compiled in 1996. Because some inconsistencies exist in the guidelines of those different wetland surveys, difference in area is expected. Some further comparison indicates that the wetland distributions derived from the preliminary wetland map are reasonable and more objective than other sources. The mapping process also indicated that the method adopted by us was efficient and cost-effective. We also found that in order to ensure comparability of the wetland maps developed at different times, a set of standard guidelines on the wetland categories to be mapped, and the mapping methods to be used must be well conceived, developed and effectively employed. We carried out some initial geographical analysis on the distribution of wetlands. | NIU ZhenGuo GONG Peng CHENG Xiao GUO JianHong WANG Lin HUANG HuaBing SHEN ShaoQing WU YunZhao WANG XiaoFeng WANG XianWei YING Qing LIANG Lu ZHANG LiNa WANG Lei YAO Qian YANG ZhenZhong GUO ZiQi DAI YongJiu | 2009 | Science China Earth Sciences2009，52，6： | 15 |
| 3 | Aerosol effects on ozone concentrations in Beijing:A model sensitivity study显示文摘Most previous O 3 simulations were based only on gaseous phase photochemistry.However,some aerosol-related processes,namely,heterogeneous reactions occurring on the aerosol surface and photolysis rate alternated by aerosol radiative influence,may affect O 3 photochemistry under high aerosol loads.A three-dimensional air quality model,Models-3/Community Multi-scale Air Quality-Model of Aerosol Dynamics,Reaction,Ionization,and Dissolution,was employed to simulate the effects of the above-mentioned processes on O 3 formation under typical high O 3 episodes in Beijing during summer.Five heterogeneous reactions,i.e.,NO 2,NO 3,N 2 O 5,HO 2,and O 3,were individually investigated to elucidate their effects on O 3 formation.The results showed that the heterogeneous reactions significantly affected O 3 formation in the urban plume.NO 2 heterogeneous reaction increased O 3 to 90 ppb,while HO 2 heterogeneous reaction decreased O 3 to 33 ppb.In addition,O 3 heterogeneous loss decreased O 3 to 31 ppb.The effects of NO 2,NO 3,and N 2 O 5 heterogeneous reactions showed opposite O 3 concentration changes between the urban and extra-urban areas because of the response of the reactions to the two types of O 3 formation regimes.When the aerosol radiative influence was included,the photolysis rate decreased and O 3 decreased significantly to 73 ppb O 3.The two aerosol-related processes should be considered in the study of O 3 formation because high aerosol concentration is a ubiquitous phenomenon that affects the urban-and regional air quality in China. | Jun Xu Yuanhang Zhang Shaoqing Zheng Youjiang He | 2012 | Journal of Environmental Sciences2012，24，4： | 15 |
| 4 | Realizing over 10% efficiency in polymer solar cell by device optimization显示文摘The low band gap polymer based on benzodithiophene(BDT)-thieno[3,4-b]thiophene(TT)backbone,PBDT-TS1,was synthesized following our previous work and the bulk heterojunction(BHJ)material comprising PBDT-TS1/PC71BM was optimized and characterized.By processing the active layer with different additives i.e.1,8-diiodooctane(DIO),1-chloronaphthalene(CN)and 1,8-octanedithiol(ODT)and optimizing the ratio of each additive in the host solvent,a high PCE of 9.98%was obtained under the condition of utilizing 3%DIO as processing additive in CB.The effect of varied additives on photovoltaic performance was illustrated with atomic force microscopy(AFM)and transmission electron microscope(TEM)measurements that explained changes in photovoltaic parameters.These results provide valuable information of solvent additive choice in device optimization of PBDTTT polymers,and the systematic device optimization could be applied in other efficient photovoltaic polymers.Apparently,this work presents a great advance in single junction PSCs,especially in PSCs with conventional architecture. | Shaoqing Zhang Long Ye Wenchao Zhao Bei Yang Qi Wang Jianhui Hou | 2015 | Science China Chemistry2015，58，2： | 12 |
| 5 | Fluorination vs. chlorination: a case study on high performance organic photovoltaic materials显示文摘Halogenation is a very efficient chemical modification method to tune the molecular energy levels, absorption spectra and molecular packing of organic semiconductors. Recently, in the field of organic solar cells(OSCs), both fluorine-and chlorinesubstituted photovoltaic materials, including donors and acceptors, demonstrated their great potentials in achieving high power conversion efficiencies(PCEs), raising a question that how to make a decision between fluorination and chlorination when designing materials. Herein, we systemically studied the impact of fluorination and chlorination on the properties of resulting donors(PBDB-T-2 F and PBDB-T-2 Cl) and acceptors(IT-4 F and IT-4 Cl). The results suggest that all the OSCs based on different donor and acceptor combinations can deliver good PCEs around 13%–14%. Chlorination is more effective than fluorination in downshifting the molecular energy levels and broadening the absorption spectra. The influence of chlorination and fluorination on the crystallinity of the resulting materials is dependent on their introduction positions. As chlorination has the advantage of easy synthesis, it is more attractive in designing low-cost photovoltaic materials and therefore may have more potential in largescale applications. | Yun Zhang Huifeng Yao Shaoqing Zhang Yunpeng Qin Jianqi Zhang Liyan Yang Wanning Li Zhixiang Wei Feng Gao Jianhui Hou | 2018 | Science China Chemistry2018，61，10： | 11 |
| 6 | Convergence of Y Chromosome STR Haplotypes from Different SNP Haplogroups Compromises Accuracy of Haplogroup Prediction显示文摘The paternally inherited Y chromosome has been widely used in forensics for personal identification,in anthropology and population genetics to understand origin and migration of human populations,and also in medical and clinical studies(Wang and Li,2013;Wang et al.,2014).There are two kinds of extremely useful markers in Y chromosome,single nucleotide polymorphism(SNP)and short tandem repeats(STRs). | Chuan-Chao Wang Ling-Xiang Wang Rukesh Shrestha Shaoqing Wen Manfei Zhang Xinzhu Tong Li Jin Hui Li | 2015 | Journal of Genetics and Genomics2015，42，7： | 8 |
| 7 | Microstructure Evolution and Tensile Properties of Ti_3Al/Ni-based Superalloy Welded Joint显示文摘In the present work,the dissimilar joining of a Ti_3AI-based alloy to a Ni-based superalloy was attempted by gas tungsten arc(GTA) welding technology.Sound joints were successfully achieved by using a Cu—Ni alloy as filler material.According to X-ray energy dispersive spectroscopy and X-ray diffraction analysis results three transitional layers at the weld/Ti_3AI interface were verified as follows:Ti_2AINb phase dissolved with Cu and Ni;AI(Cu,Ni)_2Ti,(Cu,Ni)_2Ti and(Nb,Ti) solid solution;Cu-rich phase and a complex multi-element phase.The In718/weld interface is characterized by solid solutions of Ni,Cu,Cr,Fe and Nb.The average tensile strength of the as-welded joints at room temperature is 1 63 MPa,and after a post—weld heat treatment it is increased slightly to 177 MPa.The fracture occurred at the surfacial layer of the joined Ti_3AI base alloy,indicating that the Ti_2AINb layer dissolved with Cu and Ni is the weak link of the Ti_3AI/ln71 8 joint. | Bingqing Chen Huaping Xiong Bingbing Sun Siyi Tang Shaoqing Guo Xuejun Zhang | 2014 | Journal of Materials Science & Technology2014，30，7： | 7 |
| 8 | Geochemistry and genesis of authigenic pyrite from gas hydrate accumulation system in the Qilian Mountain permafrost, Qinghai, northwest China显示文摘A type of authigenic pyrites that fully fill or semi-fill the rock fractures of drillholes with gas hydrate anomalies are found in the Qilian Mountain permafrost; this type of pyrite is known as 'fracture-filling' pyrite. The occurrence of 'fracture-filling' pyrite has a certain similarity with that of the hydrate found in this region, and the pyrite is generally concentrated in the lower part of the hydrate layer or the hydrate anomaly layer. The morphology, trace elements, rare earth elements, and sulfur isotope analyses of samples from drillhole DK-6 indicate that the 'fracture-filling' pyrites are dominated by cubic ones mainly aligned in a step-like fashion along the surfaces of rock fractures and are associated with a circular structure, lower Co/Ni and Sr/Ba, lower ?REE, higher LREE, significant Eu negative anomalies, and ? 34 SCDT positive bias. In terms of the pyrites' unique crystal morphology and geochemical characteristics and their relationship with the hydrate layers or abnormal layers, they are closely related with the accumulation system of the gas hydrate in the Qilian Mountain permafrost. As climate change is an important factor in affecting the stability of the gas hydrate, formation of fracture-filling pyrites is most likely closely related to the secondary change of the metastable gas hydrate under the regional climate warming. The distribution intensity of these pyrites indicates that when the gas hydrate stability zone(GHSZ) is narrowing, the hydrate decomposition at the bottom of the GHSZ is stronger than that at the top of the GHSZ, whereas the hydrate decomposition within the GHSZ is relatively weak. Thus, the zone between the shallowest and the deepest distribution of the fracture-filling pyrite recorded the largest possible original GHSZ. | WANG PingKang ZHU YouHai LU ZhenQuan HUANG Xia PANG ShouJi ZHANG Shuai JIANG ShaoQing LI QingHai YANG KaiLi LI Bing | 2014 | Science China Earth Sciences2014，57，9： | 6 |
| 9 | Hydrogen production from coke oven gas over LiNi/γ-Al_2O_3 catalyst modified by rare earth metal oxide in a membrane reactor显示文摘The performance of LiNi/γ-Al2O3 catalysts modified by rare earth metal oxide(La2O3 or CeO2 ) packed on BCFNO membrane reactor was discussed for the partial oxidation of methane(POM) in coke oven gas(COG) at 875 C. The NiO/γ-Al2O3 catalysts with different amounts of La2O3 and CeO2 were prepared with the same preparation method and under the same condition in order to compare the reaction performance(oxygen permeation,CH 4 conversion,H 2 and CO selectivity) on the membrane reactor. The results show that the oxygen permeation flux increased significantly with LiNiREO x /γ-Al2O3(RE = La or Ce) catalysts by adding the element of rare earth especially the Ce during the POM in COG. Such as,the Li15wt%CeO2 9wt%NiO/γ-Al2O3 catalyst with an oxygen permeation flux of 24.71 ml cm 2 min 1 and a high CH 4 conversion was obtained in 875 C. The resulted high oxygen permeation flux may be due to the added Ce that inhibited the strong interaction between Ni and Al2O3 to form the NiAl2O4 phase. In addition,the introduction of Ce leads up to an important property of storing and releasing oxygen. | Zhibin Yang Yunyan Zhang Weizhong Ding Yuwen Zhang Peijun Shen Yuding Zhou Yong Liu Shaoqing Huang Xionggang Lu | 2009 | Journal of Natural Gas Chemistry2009，18，4： | 6 |
| 10 | Realizing 11.3% efficiency in fullerene-free polymer solar cells by device optimization显示文摘In this work, photovoltaic properties of the PBDB-T:ITIC based-NF-PSCs were fully optimized and characterized by tuning the morphology of the active layers and changing the device architecture. First, donor/acceptor(D/A) weight ratios were scanned,and then further optimization was performed by using different additives, i.e. 1,8-diiodooctane(DIO), diphenyl ether(DPE),1-chloronaphthalene(CN) and N-methyl-2-pyrrolidone(NMP), on the basis of best D/A ratio(1:1, w/w), respectively. Finally,the conventional or inverted device architectures with different buffer layers were employed to fabricate NF-PSC devices, and meanwhile, the morphology of the active layers was further optimized by controlling annealing temperature and time. As a result,a record efficiency of 11.3% was achieved, which is the highest result for NF-PSCs. It's also remarkable that the inverted NF-PSCs exhibited long-term stability, i.e. the best-performing devices maintain 83% of their initial PCEs after over 4000 h storage. | Wenchao Zhao Shaoqing Zhang Jianhui Hou | 2016 | Science China Chemistry2016，59，12： | 6 |
| 11 | High adsorption of Cd(Ⅱ)by modification of synthetic zeolites Y,A and mordenite with thiourea显示文摘Zeolites Y,A and mordenite(ZY,ZA and ZM)were obtained from diatomite in a template-free system,and the products were modified by thiourea(TU).Characterization studies results indicated that the TU molecules were loaded onto the exterior surfaces of the synthetic zeolites as well as the channels.Elemental analysis and energy-dispersive X-ray spectrometer proved that the TU molecules loaded on to ZA were more than ZY and ZM.Removal of Cd(Ⅱ)was investigated,and itwas found that themodified zeolites have higher removal capacity,modified ZA is especially noticeable.In the adsorption experiments,the effects of various parameters such as sorbent content,contact time,concentration of cadmium solution,pH,selectivity and regeneration were discussed.At the best removal efficiency by modified zeolites,the maximum adsorption capacity is 94.3 mg·g^−1,103.2 mg·g^−1 and 89.7 mg·g^−1 at 25℃,respectively.The sorbents show good efficiency for the removal of Cd(Ⅱ)in the presence of different multivalent cations and have good regeneration effect.For the modified samples,removal experiments take place via ion exchange and complexation processes. | Shaoqing Zhang Tianming Lv Yang Mu Jiqi Zheng Changgong Meng | 2020 | Chinese Journal of Chemical Engineering2020，28，12： | 5 |
| 12 | Microstructure and Tensile Properties of ZK60 Alloy Fabricated by Simplified Rapid Solidification Powder Metallurgy (S-RS P/M) Process显示文摘This study investigated the microstructures and mechanical properties of ZK60 alloy prepared by a simplified rapid solidification powder metallurgy (RS P/M) processing system (S-RS P/M), which consists of warm press in dry air and hot extrusion. Microstructure characterizations showed that S-RS P/M alloy consisted of magnesium matrix and oxide stringers of~1 μm in width. TEM (transmission electron microscopy) observations illustrated nano-size magnesia particles (10-30 nm) constituted oxide stringer in detail. Due to a relatively higher volume of nano-size magnesia particle produced during S-RS P/M process, 0.2% yield strength of S-RS P/M ZK60 alloy was found to be as high as 382 MPa, which is 10% higher than that of RS P/M alloy. The improvement in mechanical properties is mainly attributed to the combination effects of Orowan mechanism and coefficient of thermal expansion (CTE) mismatch because of the approximately same average grain size. | Zhenya Zhang, Huashun Yu , Shaoqing Wang, Haitao Wang and Guanghui Min Key Laboratory of Liquid Structure and Heredity of Materials, Ministry of Education, Shandong University, Jinan 250061, China | 2010 | Journal of Materials Science & Technology2010，26，2： | 5 |
| 13 | An Examination of the Predictability of Tropical Cyclone Genesis in High-Resolution Coupled Models with Dynamically Downscaled Coupled Data Assimilation Initialization显示文摘Predicting tropical cyclone(TC)genesis is of great societal importance but scientifically challenging.It requires fineresolution coupled models that properly represent air−sea interactions in the atmospheric responses to local warm sea surface temperatures and feedbacks,with aid from coherent coupled initialization.This study uses three sets of highresolution regional coupled models(RCMs)covering the Asia−Pacific(AP)region initialized with local observations and dynamically downscaled coupled data assimilation to evaluate the predictability of TC genesis in the West Pacific.The APRCMs consist of three sets of high-resolution configurations of the Weather Research and Forecasting−Regional Ocean Model System(WRF-ROMS):27-km WRF with 9-km ROMS,and 9-km WRF with 3-km ROMS.In this study,a 9-km WRF with 9-km ROMS coupled model system is also used in a case test for the predictability of TC genesis.Since the local sea surface temperatures and wind shear conditions that favor TC formation are better resolved,the enhanced-resolution coupled model tends to improve the predictability of TC genesis,which could be further improved by improving planetary boundary layer physics,thus resolving better air−sea and air−land interactions. | Mingkui LI Shaoqing ZHANG Lixin WU Xiaopei LIN Ping CHANG Gohkan DANABASOGLU Zhiqiang WEI Xiaolin YU Huiqin HU Xiaohui MA Weiwei MA Haoran ZHAO Dongning JIA Xin LIU Kai MAO Youwei MA Yingjing JIANG Xue WANG Guangliang LIU Yuhu CHEN | 2020 | Advances in Atmospheric Sciences2020，37，9： | 4 |

| 15 | Characterization of a Novel Gain-of-Function Spotted-Leaf Mutant with Enhanced Disease Resistance in Rice显示文摘We here reported the identification and characterization of a novel gain-of-function spotted-leaf 26 (Spl26) mutant from an ethylmethylsulfone (EMS)-induced rice cultivar IR64. Spl26 displayed reddish- brown lesions that firstly appeared on the leaf tips at the early tillering stage and spread gradually downward to cover the whole leaf blades that wilted subsequently. The lesion development was light- dependent under natural conditions. Spl26 exhibited impaired photosynthetic capacity with decreased chlorophyll content and lowered photosynthetic parameters which ultimately led to the poor performance of agronomic traits. Severe cell death occurred in Spl26 in accompany with increased malonaldehyde level and membrane ion leakage rate, elevated reactive oxygen species (ROS) accumulation, altered ROS scavenging activities, increased DNA fragmentation and decreased soluble protein levels. Defense responses were activated in Spl26 with enhanced resistance to rice bacterial blight, up-regulation of defense response genes and altered endogenous hormone levels. The spotted-leaf phenotype is controlled by a single dominant nuclear gene localized to a 305 kb region between RM5490 and InDel42 on the short arm of chromosome 7. The data suggested that Spl26 is a novel gain-of-function spotted-leaf mutant with enhanced bacterial disease resistance and immunity-associated premature leaf senescence and would provide the basis for cloning of the target gene. | CHEN Ting CHEN Zheng Atul Prakash SATHE ZHANG Zhihong LI Liangjian SHANG Huihui TANG Shaoqing ZHANG Xiaobo WU Jianli | 2019 | Rice science2019，26，6： | 3 |
| 16 | Proliferation and differentiation into endothelial cells of human bone marrow mesenchymal stem cells (MSCs) on poly DL-lactic-co-glycolic acid (PLGA) films显示文摘The functional realization is the most important problem in vascular tissue engineering. The small-caliber blood vessel substitutes are prone to thrombi, which results in functional loss of blood vessels. However, this is probably due to the imper- fection of endothelial layer in the substitutes. In this study, MSCs were seeded on a series of porous PLGA films with various porosity and pore size made by sodium chloride (NaCl) particulate leaching, and cell proliferation on each film was inspected. The film made of the 75% (w/w) particulate proportion and 30―50 μm pore size maximized the proliferation rate and was chosen as the scaffolds for the differentia- tion of MSCs into endothelial cells. The induced cells expressed endothelial cells specific Flk-1, Ⅷ factor and CD34, possessed endothelial cells specific Weible-palade (W-P) body, and had the abilities of ingesting low density lipoprotein and secreting prostacyclin (PGI2). The results show that MSCs not only have the ideal biological compatibility with the porous PLGA films, but also have the potency of dif- ferentiating into functional endothelial cells, whichshould facilitate the endothelialization in vascular tissue engineering. | YUE Huimin ZHANG Lei WANG Yunfang LIANG Feng GUAN Lidong Li Shaoqing YAN Fang NAN Xue BAI Cixian LIN Feng YAN Yongnian PEI Xuetao | 2006 | Chinese Science Bulletin2006，51，11： | 3 |
| 17 | Molecular design revitalizes the low-cost PTV-polymer for highly efficient organic solar cells显示文摘Developing photovoltaic materials with simple chemical structures and easy synthesis still remains a major challenge in the industrialization process of organic solar cells(OSCs).Herein,an ester substituted poly(thiophene vinylene)derivative,PTVT-T,was designed and synthesized in very few steps by adopting commercially available raw materials.The ester groups on the thiophene units enable PTVT-T to have a planar and stable conformation.Moreover,PTVT-T presents a wide absorption band and strong aggregation effect in solution,which are the key characteristics needed to realize high performance in non-fullerene-acceptor(NFA)-based OSCs.We then prepared OSCs by blending PTVT-T with three representative fullerene-and NF-based acceptors,PC71 BM,IT-4 F and BTP-e C9.It was found that PTVT-T can work well with all the acceptors,showing great potential to match new emerging NFAs.Particularly,a remarkable power conversion efficiency of 16.20%is achieved in a PTVT-T:BTP-e C9-based device,which is the highest value among the counterparts based on PTV derivatives.This work demonstrates that PTVT-T shows great potential for the future commercialization of OSCs. | Junzhen Ren Pengqing Bi Jianqi Zhang Jiao Liu Jingwen Wang Ye Xu Zhixiang Wei Shaoqing Zhang Jianhui Hou | 2021 | National Science Review2021，8，8： | 3 |
| 18 | Influence of the replacement of alkoxyl with alkylthienyl on photovoltaic properties of two small molecule donors for organic solar cells显示文摘Two benzo[1,2-b:4,5-b￠]dithiophene(BDT)-based small molecule(SM) donor materials with identical conjugated backbones but different substitution groups, named as DRTB-O and DRTB-T, were well explored to demonstrate the influence of the replacement of alkoxy with alkylthienyl on their photovoltaic properties in fullerene-based and fullerene-free organic solar cells(OSCs). The study shows that the two SM donors possess similar absorption spectra and energy levels but different crystalline structures in solid films. The carrier transport property and phase separation morphologies of the blend films have also been fully investigated.By employing PC71 BM as the acceptor, the power conversion efficiency(PCE) of DRTB-O:PC71BM and DRTB-T:PC71BM based devices were 4.91% and 7.08%, respectively. However, by blending with IDIC, the two SM donors exhibited distinctly different photovoltaic properties in fullerene-free OSCs, and the PCE of DRTB-O:IDIC and DRTB-T:IDIC based devices were 0.15% and9.06%, respectively. These results indicate that the replacement of alkoxyl with alkylthienyl in designing SM donor materials plays an important role in the application of fullerene-free OSCs. | Shaoqing Zhang Liyan Yang Delong Liu Chang He Jianqi Zhang Yun Zhang Jianhui Hou | 2017 | Science China Chemistry2017，60，10： | 2 |

| 20 | Deep-nanometer-scale terahertz spectroscopy using a transistor geometry with metal nanogap electrodes显示文摘Terahertz(THz)spectroscopy is a powerful tool for characterizing electronic properties and vibronic excitations in various types of solids,liquids,and gases,and it has been extensively used not only for basic science but also for industrial applications.Recently,it has become necessary to understand electronic and vibronic excitations at the nanometer(nm)scale to realize state-of-the-art quantum nanodevices and the synthesis of new molecules for medicine.However,it is challenging to perform THz spectroscopy at the nm scale because the diffraction limit of electromagnetic waves hinders tight focusing of THz radiation at the nm scale.Here,we introduce a novel technique for THz spectroscopy using metal nanogap electrodes.Metal nanogap electrodes integrated with a THz antenna are employed to capture sensing targets,such as a single semiconductor quantum dot(QD)or molecule.Even extremely weak THz absorption can be detected with high sensitivity by measuring the THz-induced photocurrent through the sensing target.Taking advantage of THz-induced photocurrent spectroscopy,the electronic structures in single QDs as well as the vibrational states in single molecules are systematically investigated.The present characterization technology for nm-scale systems provides a key scientific foundation for creating nanodevices with new functions. | Ya Zhang Shaoqing Du Kazuhiko Hirakawa | 2021 | Light(Advanced Manufacturing)2021，2，4： | 2 |
