| 1 | Climate change, water resources and sustainable development in the arid and semi-arid lands of Central Asia in the past 30 years显示文摘The countries of Central Asia are collectively known as the five '-stans': Uzbekistan, Kyrgyzstan, Turkmenistan, Tajikistan and Kazakhstan. In recent times, the Central Asian region has been affected by the shrinkage of the Aral Sea, widespread desertification, soil salinization, biodiversity loss, frequent sand storms, and many other ecological disasters. This paper is a review article based upon the collection, identification and collation of previous studies of environmental changes and regional developments in Central Asia in the past 30 years. Most recent studies have reached a consensus that the temperature rise in Central Asia is occurring faster than the global average. This warming trend will not only result in a higher evaporation in the basin oases, but also to a significant retreat of glaciers in the mountainous areas. Water is the key to sustainable development in the arid and semi-arid regions in Central Asia. The uneven distribution, over consumption, and pollution of water resources in Central Asia have caused severe water supply problems, which have been affecting regional harmony and development for the past 30 years. The widespread and significant land use changes in the 1990 s could be used to improve our understanding of natural variability and human interaction in the region. There has been a positive trend of trans-border cooperation among the Central Asian countries in recent years. International attention has grown and research projects have been initiated to provide water and ecosystem protection in Central Asia. However, the agreements that have been reached might not be able to deliver practical action in time to prevent severe ecological disasters. Water management should be based on hydrographic borders and ministries should be able to make timely decisions without political intervention. Fully integrated management of water resources, land use and industrial development is essential in Central Asia. The ecological crisis should provide sufficient motivation to reach a consensus on unified water management throughout the region. | YU Yang PI Yuanyue YU Xiang TA Zhijie SUN Lingxiao Markus DISSE ZENG Fanjiang LI Yaoming CHEN Xi YU Ruide | 2019 | Journal of Arid Land2019,11,1: | 20 |
| 2 | From Independence to Interconnection--A Review of AI Technology Applied in Energy Systems显示文摘The development of diversified energy structures,distributed energy scheduling models and active participation ability of users,leads to a rapid movement toward energy system in which different energy carriers and systems interact together in a synergistic way.This energy development will face many challenges with the requirements of big data processing capability,professional skill,distributed collaboration and realtime monitoring for the energy system that demands an intelligent and flexible tool to realize the smart energy.Artificial intelligence(AI)technology has become a focus because of its better performance.This paper proposed a classification method that incorporates the intelligence of an independent energy unit(IEU)and the intelligence among interconnected energy units(IEUS)to review the development of AI technology in energy systems.The dominant structures of IEU can be considered from three aspects including perception,decision and implementation to study the optimal strategy for AI methods utilized in IEU.And considering the interaction relationship of IEUS,the AI applied for it can be described by the coordinated relationship and adversarial relationship problems to achieve consensus.By discussing the AI technologies and the potentials of AI in the energy system,some suggestions are presented to improve intelligent technologies for sustainable energy systems in the future. | Qiuye Sun Lingxiao Yang | 2019 | CSEE Journal of Power and Energy Systems2019,5,1: | 8 |
| 3 | Strong ozone production at a rural site in the North China Plain: Mixed effects of urban plumes and biogenic emissions显示文摘Regional ozone(O_3) pollution has drawn increasing attention in China over the recent decade, but the contributions from urban pollution and biogenic emissions have not been clearly elucidated. To better understand the formation of the regional O_3 problem in the North China Plain(NCP), intensive field measurements of O_3 and related parameters were conducted at a rural site downwind of Ji'nan, the capital city of Shandong province, in the summer of 2013. Markedly severe O_3 pollution was recorded, with the O_3 mixing ratios exceeding the Chinese national ambient air quality standard on 28 days(a frequency of 78%) and with a maximum hourly value of 198 ppbv. Extensive regional transport of wellprocessed urban plumes to the site was identified. An observation-constrained chemical box model was deployed to evaluate in situ photochemical O_3 production on two episodes.The results show that the in situ formation accounted for approximately 46% of the observed O_3 accumulation, while the remainder(~54%) was contributed by regional transport of the O_3-laden urban plumes. The in situ ozone production was in a mixed controlled regime that reducing either NOx or VOCs would lead to a reduction of ozone formation. Biogenic VOCs played an important role in the local ozone formation. This study demonstrates the significant mixed effects of both anthropogenic pollution from urban zones and biogenic emission in rural areas on the regional O_3 pollution in the NCP region,and may have general applicability in facilitating the understanding of the formation of secondary pollution over China. | Ruihan Zong Xue Yang Liang Wen Caihong Xu Yanhong Zhu Tianshu Chen Lan Yao Liwei Wang Junmei Zhang Lingxiao Yang Xinfeng Wang Min Shao Tong Zhu Likun Xue Wenxing Wang | 2018 | Journal of Environmental Sciences2018,30,9: | 8 |
| 4 | Can climate change influence agricultural GTFP in arid and semi-arid regions of Northwest China?显示文摘There are eight provinces and autonomous regions(Gansu Province,Ningxia Hui Autonomous Region,Xinjiang Uygur Autonomous Region,Inner Mongolia Autonomous Region,Tibet Autonomous Region,Qinghai Province,Shanxi Province,and Shaanxi Province)in Northwest China,most areas of which are located in arid and semi-arid regions(northwest of the 400 mm precipitation line),accounting for 58.74%of the country's land area and sustaining approximately 7.84×10^6 people.Because of drought conditions and fragile ecology,these regions cannot develop agriculture at the expense of the environment.Given the challenges of global warming,the green total factor productivity(GTFP),taking CO2 emissions as an undesirable output,is an effective index for measuring the sustainability of agricultural development.Agricultural GTFP can be influenced by both internal production factors(labor force,machinery,land,agricultural plastic film,diesel,pesticide,and fertilizer)and external climate factors(temperature,precipitation,and sunshine duration).In this study,we used the Super-slacks-based measure(Super-SBM)model to measure agricultural GTFP during the period 2000-2016 at the regional level.Our results show that the average agricultural GTFP of most provinces and autonomous regions in arid and semi-arid regions underwent a fluctuating increase during the study period(2000-2016),and the fluctuation was caused by the production factors(input and output factors).To improve agricultural GTFP,Shaanxi,Shanxi,and Gansu should reduce agricultural labor force input;Shaanxi,Inner Mongolia,Gansu,and Shanxi should decrease machinery input;Shaanxi,Inner Mongolia,Xinjiang,and Shanxi should reduce fertilizer input;Shaanxi,Xinjiang,Gansu,and Ningxia should reduce diesel input;Xinjiang and Gansu should decrease plastic film input;and Gansu,Shanxi,and Inner Mongolia should cut pesticide input.Desirable output agricultural earnings should be increased in Qinghai and Tibet,and undesirable output(CO2 emissions)should be reduced in Inner Mongolia,Xinjiang,Gansu,and Shaanxi.Agricultural GTFP is influenced not only by internal production factors but also by external climate factors.To determine the influence of climate factors on GTFP in these provinces and autonomous regions,we used a Geographical Detector(Geodetector)model to analyze the influence of climate factors(temperature,precipitation,and sunshine duration)and identify the relationships between different climate factors and GTFP.We found that temperature played a significant role in the spatial heterogeneity of GTFP among provinces and autonomous regions in arid and semi-arid regions.For Xinjiang,Inner Mongolia,and Tibet,a suitable average annual temperature would be in the range of 7℃-9℃;for Gansu,Shanxi,and Ningxia,it would be 11℃-13℃;and for Shaanxi,it would be 15℃-17℃.Stable climatic conditions and more efficient production are prerequisites for the development of sustainable agriculture.Hence,in the agricultural production process,reducing the redundancy of input factors is the best way to reduce CO2 emissions and to maintain temperatures,thereby improving the agricultural GTFP.The significance of this study is that it explores the impact of both internal production factors and external climatic factors on the development of sustainable agriculture in arid and semi-arid regions,identifying an effective way forward for the arid and semi-arid regions of Northwest China. | FENG Jian ZHAO Lingdi ZHANG Yibo SUN Lingxiao YU Xiang YU Yang | 2020 | Journal of Arid Land2020,12,5: | 6 |
| 5 | Temperature-induced Lifshitz transition in topological insulator candidate HfTe_5显示文摘The ongoing discoveries and studies of novel topological quantum materials have become an emergent and important field of condensed matter physics.Recently,HfTe_5 ignited renewed interest as a candidate of a novel topological material.The single-layer HfTe_5 is predicted to be a two-dimensional large band gap topological insulator and can be stacked into a bulk that may host a temperature-driven topological phase transition.Historically,HfTe_5 attracted considerable interest for its anomalous transport properties characterized by a peculiar resistivity peak accompanied by a sign reversal carrier type.The origin of the transport anomaly remains under a hot debate.Here we report the first high-resolution laser-based angle-resolved photoemission measurements on the temperature-dependent electronic structure in HfTe_5.Our results indicated that a temperature-induced Lifshitz transition occurs in HfTe_5,which provides a natural understanding on the origin of the transport anomaly in HfTe_5.In addition,our observations suggest that HfTe_5 is a weak topological insulator that is located at the phase boundary between weak and strong topological insulators at very low temperature. | Yan Zhang Chenlu Wang Guodong Liu Aiji Liang Lingxiao Zhao Jianwei Huang Qiang Gao Bing Shen Jing Liu Cheng Hu Wenjuan Zhao Genfu Chen Xiaowen Jia Li Yu Lin Zhao Shaolong He Fengfeng Zhang Shenjin Zhang Feng Yang Zhimin Wang Qinjun Peng Zuyan Xu Chuangtian Chen Xingjiang Zhou | 2017 | Science Bulletin2017,62,13: | 4 |
| 6 | A Nonresonant Hybridized Electromagnetic-Triboelectric Nanogenerator for Irregular and Ultralow Frequency Blue Energy Harvesting显示文摘As a promising renewable energy source,it is a challenging task to obtain blue energy,which is irregular and has an ultralow frequency,due to the limitation of technology.Herein,a nonresonant hybridized electromagnetic-triboelectric nanogenerator was presented to efficiently obtain the ultralow frequency energy.The instrument adopted the flexible pendulum structure with a precise design and combined the working principle of electromagnetism and triboelectricity to realize the all-directional vibration energy acquisition successfully.The results confirmed that the triboelectric nanogenerator(TENG)had the potential to deliver the maximum power point of about 470μW while the electromagnetic nanogenerator(EMG)can provide 523 mW at most.The conversion efficiency of energy of the system reached 48.48%,which exhibited a remarkable improvement by about 2.96 times,due to the elastic buffering effect of the TENG with the double helix structure.Furthermore,its ability to collect low frequency wave energy was successfully proven by a buoy in Jialing River.This woke provides an effective candidate to harvest irregular and ultralow frequency blue energy on a large scale. | Weibo Xie Lingxiao Gao Lingke Wu Xin Chen Fayang Wang Daqiao Tong Jian Zhang Jianyu Lan Xiaobin He Xiaojing Mu Ya Yang | 2021 | Research2021,,1: | 4 |
| 7 | A preliminary analysis and discussion of the condominium building collapse in surfside,Florida,US,June 24,2021显示文摘On June 24,2021,a 40-year-old reinforced concrete flat plate structure building in Miami suffered a sudden partial collapse.This study analyzed the overall performance and key components of the collapsed building based on the building design codes(ACI-318 and GB 50010).Punching shear and post-punching performances of typical slabcolumn joints are also studied through the refined finite element analysis.The collapse process was simulated and visualized using a physics engine.By way of these analyses,weak design points of the collapsed building are highlighted.The differences between the reinforcement detailing of the collapsed building and the requirements of the current Chinese code are discussed,together with a comparison of the punching shear and post-punching performances.The simulated collapse procedure and debris distribution are compared with the actual collapse scenes. | Xinzheng LU Hong GUAN Hailin SUN Yi LI Zhe ZHENG Yifan FEI Zhi YANG Lingxiao ZUO | 2021 | Frontiers of Structural and Civil Engineering2021,15,5: | 4 |
| 8 | Histological and Ultrastructural Features for Proliferation Inhibition by Delivery of Exogenous p27^(Kip1) to Rabbit Models after Glaucoma Filtration Surgery显示文摘Purpose: To investigate postoperative inhibition of cell proliferation in animals treated with exogenous p27Kip1 during an experimental glaucoma filtration surgery (GFS) by histological and ultrastructural examinations. Methods:The primer was designed according to p27Kip1 gene sequence of GenBank..The p27Kip1-expressing adenovirus-mediated Ad-p27 was constructed according to standard techniques..Gene therapy was performed by subconjunctival delivery of Ad-p27,mitomycin C(MMC) and PBS served as controls..Histological and ultastructural changes at surgical sites were observed for 28 days postoperatively. Results: Histologically, evident cellular proliferation induced by Ad-p27 was observed on day 7,.with appreciable filtering cavity. However, thin conjunctival layers were noted, and the number of fibroblasts decreased in the Tenon's capsule on day 14. On day 28, the filtering cavity partially disappeared. The histological features of the animals with MMC delivery were similar to those treated by Ad-p27..In contrast,.in the PBS treatment group, thick conjunctival layers were observed, and the number of goblet cells and fibroblasts, increased markedly..The filtering cavity disappeared at postoperative day 21. Twenty eight day postoperatively,.ultrastructural findings showed that most conjunctival epithelial cells in the Ad-p27 treatment group were under static state,.and that organelles were inactive. The number of goblet cells,.and the secretion of mucin,.were decreased..The amount of fibroblasts also decreased with partial apoptotic cells. The ultrastructural features presented by rabbits with the MMC delivery resembled those treated with Ad-p27. In the PBS treatment group, the number of conjunctival epithelial cells increased; the amount of goblet cells increased as the secretion of mucin was strengthened, and a substantial amount of fibroblasts were observed with active and productive organelles. Conclusion: Ad-p27 inhibits the proliferation of Tenon's capsule fibroblasts at surgical sites, and suppresses the formation of scars, thereby promoting surgical efficacy. | Jiangang Yang Pengrui Sun Lingxiao Zhou Xiaoyan Li Yong Zhang Naixue Sun | 2012 | Eye Science2012,27,3: | 3 |
| 9 | Small changes in the length of diselenide bond-containing linkages exert great influences on the antitumor activity of docetaxel homodimeric prodrug nanoassemblies显示文摘Homodimeric prodrug-based self-assembled nanoparticles,with carrier-free structure and ultrahigh drug loading,is drawing more and more attentions.Homodimeric prodrugs are composed of two drug molecules and a pivotal linkage.The influence of the linkages on the self-assembly,in vivo fate and antitumor activity of homodimeric prodrugs is the focus of research.Herein,three docetaxel(DTX)homodimeric prodrugs are developed using different lengths of diselenide bond-containing linkages.Interestingly,compared with the other two linkages,the longest diselenide bond-containing linkage could facilitate the self-delivery of DTX prodrugs,thus improving the stability,circulation time and tumor targeting of prodrug nanoassemblies.Besides,the extension of linkages reduces the redox-triggered drug release and cytotoxicity of prodrug nanoassemblies in tumor cells.Although the longest diselenide bond-containing prodrug nanoassemblies possessed the lowest cytotoxicity to 4T1 cells,their stable nanostructure maintained intact during circulation and achieve the maximum accumulation of DTX in tumor cells,which finally“turned the table”.Our study illustrates the crucial role of linkages in homodimeric prodrugs,and gives valuable proposal for the development of advanced nano-DDS for cancer treatment. | Lingxiao Li Shiyi Zuo Fudan Dong Tian Liu Yanlin Gao Yinxian Yang Xin Wang Jin Sun Bingjun Sun Zhonggui He | 2021 | Asian Journal of Pharmaceutical Sciences2021,16,3: | 3 |
| 10 | Composition and mixing state of water soluble inorganic ions during hazy days in a background region of North China显示文摘Knowledge of haze particles in background areas of North China is limited, although they have been studied well in urban settings. Atmospheric aerosol particles were collected at a background site in the North China Plain during 16–31 January, 2011. Water soluble inorganic ions of PM2.5 and physicochemical characteristics of individual particles on hazy and clean days were measured by Ion Chromatography(IC) and Transmission Electron Microscopy(TEM), respectively. Average PM2.5 mass concentration was 50.4±29.9 μg m?3 with 62.5±26.8 μg m?3 on hazy days and 19.9±11.5 μg m?3 on clean days. SO42?, NO3?, and NH4+ with a combined mass concentration of 19.0±11.5 μg m?3 accounted for 69.8%–89.4% of the total water soluble inorganic ions. Size distributions of SO42? and NH4+ showed one unimodal peak at 0.56–1.8 μm on hazy days, whereas NO3? appeared as bimodal peaks at 0.56–1.8 and 5.6–10 μm, respectively. Individual particle analyses showed that the dominant aerosols were a mixture of sulfate, nitrate, and carbonaceous species, which together determine their mixing states. 48-h air mass back trajectories on hazy days suggested that air masses crossed the polluted continental areas(such as Jing-jin-ji region and Shandong province) and entrained ground air pollutants 11–19 hours before reaching the background area. During long-range transport particles undergo ageing and tend to be internally mixed mainly due to condensation in the background atmosphere. Our results suggest that hygroscopic and optical properties of these aerosol particles in the background area differ substantially from those in urban areas. | LU YaLing CHI JianWei YAO Lan YANG LingXiao LI WeiJun WANG ZiFa WANG WenXing | 2015 | Science China Earth Sciences2015,58,11: | 3 |
| 11 | Particle size distributions, PM2.5 concentrations and water- soluble inorganic ions in different public indoor environments: a case study in Jinan, China显示文摘In this study, we collected particles with aerodynamic diameter≤2.5μm (PM2.5) from three different public indoor places (a supermarket, a commercial office, and a university dining hall) in Jinan, a medium-sized city located in northern China. Water- soluble inorganic ions of PM2.5 and particle size distributions were also measured. Both indoor and outdoor PM2.5 levels (102.3-143.8 μg·m- 3 and 160.2-301.3 μg·m-3, respectively) were substantially higher than the value recommended by the World Health Organization (25 I.μg·m-3), and outdoor sources were found to be the major contributors to indoor pollutants. Diurnal particle number size distributions were different, while the maximum volume concentrations all appeared to be approximately 300nm in the three indoor locations. Concentrations of indoor and outdoor PM2.5 were shown to exhibit the same variation trends for the supermarket and dining hall. For the office, PM2.5 concentrations during nighttime were observed to decrease sharply. Among others, SO4^2-, NH4+ and NO3- were found to be the dominant water-soluble ions of both indoor and outdoor particles. Concentrations of NO3- in the supermarket and office during the daytime were observed to decrease sharply, which might be attributed to the fact that the indoor temperature was much higher than the outdoor temperature. In addition, domestic activities such as cleaning, water usage, cooking, and smoking also played roles in degraded indoor air quality. However, the results obtained here might be negatively impacted by the small number of samples and short sampling durations. | Can DONG Lingxiao YANG Chao YAN Qi YUAN Yangchun YU Wenxing WANG | 2013 | Frontiers of Environmental Science & Engineering2013,7,1: | 3 |
| 12 | Simultaneous diffusion of cation and anion to access N,S cocoordinated Bi-sites for enhanced CO_(2) electroreduction显示文摘Developing highly active single-atom sites catalysts for electrochemical reduction of CO_(2) is an effective and environmental-friendly strategy to promote carbon-neutral energy cycle and ameliorate global climate issues.Herein,we develop an atomically dispersed N,S co-coordinated bismuth atom sites catalyst(Bi-SAs-NS/C)via a cation and anion simultaneous diffusion strategy for electrocatalytic CO_(2) reduction.In this strategy,the bonded Bi cation and S anion are simultaneously diffused into the nitrogen-doped carbon layer in the form of Bi2S3.Then Bi is captured by the abundant N-rich vacancies and S is bonded with carbons.support at high temperature,formed the N,S co-coordinated Bi sites.Benefiting from the simultaneous diffusion of Bi and S,different electronegative N and S can be effectively co-coordinated with Bi,forming the uniform Bi-N_(3)S/C sites.The synthesized.Bi-SAs-NS/C exhibits a high selectivity towards CO with over 88%Faradaic efficiency in a wide potential range,and achieves a maximum FE_(CO)of 98.3%at-0.8 V vs.RHE with a current density of 10.24 mA·cm^(-2),which can keep constant with negligible degradation in 24 h continuous electrolysis.Experimental results and theoretical calculations reveal that the significantly improved catalytic performance of Bi-SAs-NS/C than Bi-SAs-N/C is ascribed to the replacement of one coordinated-N with low electronegative S in Bi-N_(4)C center,which can greatly reduce the energy barrier of the intermediate formation in rate-limiting step and increase the reaction kinetics.This work provides an effective strategy for rationally designing highly active single-atom sites;catalysts for efficient electrocatalysis with optimized electronic structure. | Zhiyuan Wang Chun Wang Yidong Hu Shuai Yang Jia Yang Wenxing Chen Huang Zhou Fangyao Zhou Lingxiao Wang Junyi Du Yafei Li Yuen Wu | 2021 | Nano Research2021,14,8: | 2 |
| 13 | Spatiotemporal changes in water,land use,and ecosystem services in Central Asia considering climate changes and human activities显示文摘Central Asia is located in the hinterland of Eurasia,comprising Kazakhstan,Uzbekistan,Kyrgyzstan,Turkmenistan,and Tajikistan;over 93.00%of the total area is dryland.Temperature rise and human activities have severe impacts on the fragile ecosystems.Since the 1970s,nearly half the great lakes in Central Asia have shrunk and rivers are drying rapidly owing to climate changes and human activities.Water shortage and ecological crisis have attracted extensive international attention.In general,ecosystem services in Central Asia are declining,particularly with respect to biodiversity,water,and soil conservation.Furthermore,the annual average temperature and annual precipitation in Central Asia increased by 0.30℃/decade and 6.9 mm/decade in recent decades,respectively.Temperature rise significantly affected glacier retreat in the Tianshan Mountains and Pamir Mountains,which may intensify water shortage in the 21st century.The increase in precipitation cannot counterbalance the aggravation of water shortage caused by the temperature rise and human activities in Central Asia.The population of Central Asia is growing gradually,and its economy is increasing steadily.Moreover,the agricultural land has not been expended in the last two decades.Thus,water and ecological crises,such as the Aral Sea shrinkage in the 21st century,cannot be attributed to agriculture extension any longer.Unbalanced regional development and water interception/transfer have led to the irrational exploitation of water resources in some watersheds,inducing downstream water shortage and ecological degradation.In addition,accelerated industrialization and urbanization have intensified this process.Therefore,all Central Asian countries must urgently reach a consensus and adopt common measures for water and ecological protection. | YU Yang CHEN Xi Ireneusz MALIK Malgorzata WISTUBA CAO Yiguo HOU Dongde TA Zhijie HE Jing ZHANG Lingyun YU Ruide ZHANG Haiyan SUN Lingxiao | 2021 | Journal of Arid Land2021,13,9: | 2 |
| 14 | Phylogenomic Insights into Deep Phylogeny of Angiosperms Based on Broad Nuclear Gene Sampling显示文摘Angiosperms(flowering plants)are the most diverse and species-rich group of plants.The vast majority(99.95%)of angiosperms form a clade called Mesangiospermae,which is subdivided into five major groups:eudicots,monocots,magnoliids,Chloranthales,and Ceratophyllales.The relationships among these Mesangiospermae groups have been the subject of long debate.In this study,we assembled a phylogenomic dataset of 1594 genes from 151 angiosperm taxa,including representatives of all five lineages,to investigate the phylogeny of major angiosperm lineages under both coalescent-and concatenationbased methods.We dissected the phylogenetic signal and found that more than half of the genes lack phylogenetic information for the backbone of angiosperm phylogeny.We further removed the genes with weak phylogenetic signal and showed that eudicots,Ceratophyllales,and Chloranthales form a clade,with magnoliids and monocots being the next successive sister lineages.Similar frequencies of gene tree conflict are suggestive of incomplete lineage sorting along the backbone of the angiosperm phylogeny.Our analyses suggest that a fully bifurcating species tree may not be the best way to represent the early radiation of angiosperms.Meanwhile,we inferred that the crown-group angiosperms originated approximately between 255.1 and 222.2 million years ago,and Mesangiospermae diversified into the five extant groups in a short time span(27 million years)at the Early to Late Jurassic. | Lingxiao Yang Danyan Su Xin Chang Charles SPFoster Linhua Sun Chien-Hsun Huang Xiaofan Zhou Liping Zeng Hong Ma Bojian Zhong | 2020 | Plant Communications2020,1,2: | 2 |
| 15 | Temporal and spatial variations of net primary productivity and its response to groundwater of a typical oasis in the Tarim Basin, China显示文摘Net primary productivity (NPP) of the vegetation in an oasis can reflect the productivity capacity of a plant community under natural environmental conditions. Owing to the extreme arid climate conditions and scarce precipitation in the arid oasis regions, groundwater plays a key role in restricting the development of the vegetation. The Qira Oasis is located on the southern margin of the Taklimakan Desert (Tarim Basin, China) that is one of the most vulnerable regions regarding vegetation growth and water scarcity in the world. Based on remote sensing images of the Qira Oasis and daily meteorological data measured by the ground stations during the period 2006-2019, this study analyzed the temporal and spatial patterns of NPP in the oasis as well as its relation with the variation of groundwater depth using a modified Carnegie Ames Stanford Approach (CASA) model. At the spatial scale, NPP of the vegetation decreased from the interior of the Qira Oasis to the margin;at the temporal scale, NPP of the vegetation in the oasis fluctuated significantly (ranging from 29.80 to 50.07 g C/(m2•month)) but generally showed an increasing trend, with the average increase rate of 0.07 g C/(m2•month). The regions with decreasing NPP occupied 64% of the total area of the oasis. During the study period, NPP of both farmland and grassland showed an increasing trend, while that of forest showed a decreasing trend. The depth of groundwater was deep in the south of the oasis and shallow in the north, showing a gradual increasing trend from south to north. Groundwater, as one of the key factors in the surface change and evolution of the arid oasis, determines the succession direction of the vegetation in the Qira Oasis. With the increase of groundwater depth, grassland coverage and vegetation NPP decreased. During the period 2008-2015, with the recovery of groundwater level, NPP values of all types of vegetation with different coverages increased. This study will provide a scientific basis for the rational utilization and sustainable management of groundwater resources in the oasis. | SUN Lingxiao YU Yang GAO Yuting ZHANG Haiyan YU Xiang HE Jing WANG Dagang Ireneusz MALIK Malgorzata WISTUBA YU Ruide | 2021 | Journal of Arid Land2021,13,11: | 2 |

| 18 | Green‑Solvent Processed Blade‑Coating Organic Solar Cells with an Efficiency Approaching 19%Enabled by Alkyl‑Tailored Acceptors显示文摘Power-conversion-efficiencies(PCEs)of organic solar cells(OSCs)in laboratory,normally processed by spin-coating technology with toxic halogenated solvents,have reached over 19%.However,there is usually a marked PCE drop when the bladecoating and/or green-solvents toward large-scale printing are used instead,which hampers the practical development of OSCs.Here,a new series of N-alkyl-tailored small molecule acceptors named YR-SeNF with a same molecular main backbone are developed by combining selenium-fused central-core and naphthalene-fused endgroup.Thanks to the N-alkyl engineering,NIR-absorbing YR-SeNF series show different crystallinity,packing patterns,and miscibility with polymeric donor.The studies exhibit that the molecular packing,crystallinity,and vertical distribution of active layer morphologies are well optimized by introducing newly designed guest acceptor associated with tailored N-alkyl chains,providing the improved charge transfer dynamics and stability for the PM6:L8-BO:YRSeNF-based OSCs.As a result,a record-high PCE approaching 19%is achieved in the blade-coating OSCs fabricated from a greensolvent o-xylene with high-boiling point.Notably,ternary OSCs offer robust operating stability under maximum-power-point tracking and well-keep>80%of the initial PCEs for even over 400 h.Our alkyl-tailored guest acceptor strategy provides a unique approach to develop green-solvent and blade-coating processed high-efficiency and operating stable OSCs,which paves a way for industrial development. | Hairui Bai Ruijie Ma Wenyan Su Top Archie Dela Pea Tengfei Li Lingxiao Tang Jie Yang Bin Hu Yilin Wang Zhaozhao Bi Yueling Su Qi Wei Qiang Wu Yuwei Duan Yuxiang Li Jiaying Wu Zicheng Ding Xunfan Liao Yinjuan Huang Chao Gao Guanghao Lu Mingjie Li Weiguo Zhu Gang Li Qunping Fan Wei Ma | 2023 | Nano-Micro Letters2023,15,12: | 1 |
