2GIS-based Effect Assessment of Soil Erosion Before and After Gully Land Consolidation: A Case Study of Wangjiagou Project Region, Loess Plateau显示文摘The Loess Plateau is one typical area of serious soil erosion in the world. China has implemented ′Grain for Green′(GFG) project to restore the eco-environment of the Loess Plateau since 1999. With the GFG project subsidy approaching the end, it is concerned that farmers of fewer subsidies may reclaim land again. Thus, ′Gully Land Consolidation Project′(GLCP) was initiated in 2010. The core of the GLCP was to create more land suitable for farming in gullies so as to reduce land reclamation on the slopes which are ecological vulnerable areas. This paper aims to assess the effect of the GLCP on soil erosion problems by studying Wangjiagou project region located in the central part of Anzi valley in the middle of the Loess Plateau, mainly using the revised universal soil loss equation(RUSLE) based on GIS. The findings show that the GLCP can help to reduce soil shipment by 9.87% and it creates more terraces and river-nearby land suitable for farming which account for 27.41% of the whole study area. Thus, it is feasible to implement the GLCP in places below gradient 15°, though the GLCP also intensifies soil erosion in certain places such as field ridge, village land, floodplain, natural grassland, and shrub land. In short, the GLCP develops new generation dam land and balances the short-term and long-term interests to ease the conflicts between economic development and environmental protection. Furthermore, the GLCP and the GFG could also be combined preferably. On the one hand, the GFG improves the ecological environment, which could offer certain safety to the GLCP, on the other hand, the GLCP creates more farmland favorable for farming in gullies instead of land reclamation on the slopes, which could indirectly protect the GFG project.LIU Yansui GUO Yanjun LI Yurui LI Yuheng 2015Chinese Geographical Science2015,25,2:30

5Nanoplasmonic waveguides: towards applications in integrated nanophotonic circuits显示文摘The properties of propagating surface plasmon polaritons(SPPs)along one-dimensional metal structures have been investigated for more than 10 years and are now well understood.Because of the high confinement of electromagnetic energy,propagating SPPs have been considered to represent one of the best potential ways to construct next-generation circuits that use light to overcome the speed limit of electronics.Many basic plasmonic components have already been developed.In this review,researches on plasmonic waveguides are reviewed from the perspective of plasmonic circuits.Several circuit components are constructed to demonstrate the basic function of an optical digital circuit.In the end of this review,a prototype for an SPP-based nanochip is proposed,and the problems associated with building such plasmonic circuits are discussed.A plasmonic chip that can be practically applied is expected to become available in the near future.Yurui Fang Mengtao Sun 2015Light(Science & Applications)2015,4,1:19

7Industrial development and land use/cover change and their effects on local environment:a case study of Changshu in eastern coastal China显示文摘The interactions among industrial development,land use/cover change (LUCC), and environmentaleffects in Changshu in the eastern coastal China wereanalyzed using high-resolution Landsat TM data in 1990,1995, 2000, and 2006, socio-economic data and waterenvironmental quality monitoring data from researchinstitutes and governmental departments. Three phases ofindustrial development in Changshu were examined (i.e.,the three periods of 1990 to 1995, 1995 to 2000, and 2000to 2006). Besides industrial development and rapidurbanization, land use/cover in Changshu had changeddrastically from 1990 to 2006. This change was characterizedby major replacements of farmland by urban and ruralsettlements, artificial ponds, forested and constructed land.Industrialization, urbanization, agricultural structureadjustment, and rural housing construction were themajor socio-economic driving forces of LUCC inChangshu. In addition, the annual value of ecosystemservices in Changshu decreased slightly during 1990-2000, but increased significantly during 2000-2006.Nevertheless, the local environmental quality in Changshu,especially in rural areas, has not yet been improvedsignificantly. Thus, this paper suggests an increasedattention to fully realize the role of land supply inadjustment of environment-friendly industrial structureand urban-rural spatial restructuring, and translating theland management and environmental protection policiesinto an optimized industrial distribution and land-use pattern.Yurui LI Hualou LONG Yansui LIU 2010Frontiers of Environmental Science & Engineering2010,4,4:13
8Nanowire-supported plasmonic waveguide for remote excitation of surface-enhanced Raman scattering显示文摘Due to its amazing ability to manipulate light at the nanoscale,plasmonics has become one of the most interesting topics in the field of light–matter interaction.As a promising application of plasmonics,surface-enhanced Raman scattering(SERS)has been widely used in scientific investigations and material analysis.The large enhanced Raman signals are mainly caused by the extremely enhanced electromagnetic field that results from localized surface plasmon polaritons.Recently,a novel SERS technology called remote SERS has been reported,combining both localized surface plasmon polaritons and propagating surface plasmon polaritons(PSPPs,or called plasmonic waveguide),which may be found in prominent applications in special circumstances compared to traditional local SERS.In this article,we review the mechanism of remote SERS and its development since it was first reported in 2009.Various remote metal systems based on plasmonic waveguides,such as nanoparticle–nanowire systems,single nanowire systems,crossed nanowire systems and nanowire dimer systems,are introduced,and recent novel applications,such as sensors,plasmon-driven surface-catalyzed reactions and Raman optical activity,are also presented.Furthermore,studies of remote SERS in dielectric and organic systems based on dielectric waveguides remind us that this useful technology has additional,tremendous application prospects that have not been realized in metal systems.Yingzhou Huang Yurui Fang Zhenglong Zhang Ling Zhu Mengtao Sun 2014Light(Science & Applications)2014,3,1:8
92D graphdiyne materials:challenges and opportunities in energy field显示文摘Graphdiyne(GDY),a novel two-dimensional(2D)carbon allotrope featuring one-atom-thick planar layers of sp andhybridized carbon network,is a rapidly rising star on the horizon of materials science.Because of its unparalleled structural,electronic,chemical and physical properties,it has been receiving unprecedented increases from fundamental studies to practical applications,particularly the field of energetic materials.In this review,we aim at providing an up-to-date comprehensive overview on the state-of-the-art research into GDY,from theoretical studies to the key achievements in the development of new GDY-based energetic materials for energy storage and conversion.By reviewing the state-of-the-art achievements,we aim to address the benefits and issues of GDY-based materials,as well as highlighting the existing key challenges and future opportunities in this exciting field.Yurui Xue Yuliang Li Jin Zhang Zhongfan Liu Yuliang Zhao 2018Science China Chemistry2018,61,7:7
10Further analyses of variation of ribosome DNA copy number and polymorphism in ciliates provide insights relevant to studies of both molecular ecology and phylogeny显示文摘Sequence-based approaches, such as analyses of ribosome DNA(rDNA) clone libraries and high-throughput amplicon sequencing, have been used extensively to infer evolutionary relationships and elucidate the biodiversity in microbial communities.However, recent studies demonstrate both r DNA copy number variation and intra-individual(intra-genomic) sequence variation in many organisms, which challenges the application of the rDNA-based surveys. In ciliates, an ecologically important clade of microbial eukaryotes, rDNA copy number and sequence variation are rarely studied. In the present study, we estimate the intraindividual small subunit rDNA(SSU r DNA) copy number and sequence variation in a wide range of taxa covering nine classes and 18 orders of the phylum Ciliophora. Our studies reveal that:(i) intra-individual sequence variation of SSU rDNA is ubiquitous in all groups of ciliates detected and the polymorphic level varies among taxa;(ii) there is a most common version of SSU rDNA sequence in each cell that is highly predominant and may represent the germline micronuclear template;(iii)compared with the most common version, other variant sequences differ in only 1–3 nucleotides, likely generated during macronuclear(somatic) amplification;(iv) the intra-cell sequence variation is unlikely to impact phylogenetic analyses;(v) the rDNA copy number in ciliates is highly variable, ranging from 103 to 106, with the highest record in Stentor roeselii. Overall,these analyses indicate the need for careful consideration of SSU r DNAvariation in analyses of the role of ciliates in ecosystems.Yurui Wang Chundi Wang Yaohan Jiang Laura A.Katz Feng Gao Ying Yan 2019Science China(Life Sciences)2019,62,2:7
11Histone methyltransferase TXRl is required for both H3 and H3.3lysine 27 methylation in the well-known ciliated protist Tetrahymena thermophila显示文摘DNA replication elongation is tightly controlled by histone-modifying enzymes.Our previous studies showed that the histone methytransferase TXRl(Tetrahymena Trithorax related protein 1) specifically catalyzes H3K27 monomethylation and affects DNA replication elongation in Tetrahymena thermophila.In this study,we investigated whether TXRl has a substrate preference to the canonical H3 over the replacement variant H3.3.We demonstrated by histone mutagenesis that K27 Q mutation in H3.3further aggravated the replication stress phenotype of K27 Q mutation in canonical H3,supporting H3.3 as a physiologically relevant substrate of TXRl.This result is in apparent contrast to the strong preference for canonical H3 recently reported in Arabidopsis homologues ATXR5 and ATXR6,and further corroborates the role of TXRl in DNA replication.Xiaolu Zhao Yuanyuan Wang Yurui Wang Yifan Liu Shan Gao 2017Science China(Life Sciences)2017,60,3:7
12Enzymatic and chemical mapping of nucleosome distribution in purified micro- and macronuclei of the ciliated model organism, Tetrahymenathermophila显示文摘Genomic distribution of the nucleosome, the basic unit of chromatin, contains important epigenetic information. To map nucleosome distribution in structurally and functionally differentiated micronucleus(MIC) and macronucleus(MAC) of the ciliate Tetrahymena thermophila, we have purified MIC and MAC and performed micrococcal nuclease(MNase) digestion as well as hydroxyl radical cleavage. Different factors that may affect MNase digestion were examined, to optimize mono-nucleosome production. Mono-nucleosome purity was further improved by ultracentrifugation in a sucrose gradient. As MNase concentration increased, nucleosomal DNA sizes in MIC and MAC converged on 147 bp, as expected for the nucleosome core particle. Both MNase digestion and hydroxyl radical cleavage consistently showed a nucleosome repeat length of^200 bp in MAC of Tetrahymena, supporting ~50 bp of linker DNA. Our work has systematically tested methods currently available for mapping nucleosome distribution in Tetrahymena, and provided a solid foundation for future epigenetic studies in this ciliated model organism.Xiao Chen Shan Gao Yifan Liu Yuanyuan Wang Yurui Wang Weibo Song 2016Science China(Life Sciences)2016,59,9:5

14Biogenic carbonate formation and sedimentation in the Xisha Islands: evidences from living Halimeda显示文摘A recent island survey reveals that the Xuande Atoll and the Yongle Atoll in the Xisha Islands can be classified into one of two systems: the depleted atoll system and growth atoll system; the survey also indicates that the decreased area of several shoals is an unbearable burden for the Xisha Islands, of which the largest island area is 2.13 km2 and the minimum elevation is 1.4 m. According to a survey on the ecological characteristics of Halimeda in the Laolongtou breaker zone of Shidao Island in the Xisha Islands, the green and white living Halimeda are collected,the isotopic ages of 14 C contained in the Halimeda are shown to be 27 years and 55 years, respectively, and carbonate mainly occurs in five types, i.e., luster, segment, sand, sand grain, and marl in the formation. The Halimeda segments mainly provide the carbonate sediments of long-term biogenic deposits in the reef environment and the annual productivity per area is 60–100 g/m2; the characteristics of the microstructure of the Halimeda are analyzed, the aragonite raphide carbonate is deposited and enriched in the cortexes, medullas and cysts, and the Halimeda generally contain major elements such as C, O, Ca, Cl, Mg, K, Na, S and Al, and are rich in trace elements such as tellurium(Te), rhodium(Rh) and strontium. It is believed that the Halimeda grow slowly,including the biotic community of reef corals in the reef areas, thus they possess an environmental remediation capacity, but it takes much time to remedy the environment, and it is necessary to make the law to protect the diversity and vulnerability of the Xisha marine ecology, the ecology of the reef community and the island environment in a scientific way. As indicated in the survey, under the background of global warming and sea-level rise, the discovery of large amounts of Halimeda in the Laolongtou sea area is significant for the natural increase of the depleted atoll system of the Xuande Atoll, while the Halimeda segments represent the primary form of the fossil Halimeda, of which the species can be identified and preserved in great numbers under geological conditions. The Miocene was discovered in large amounts in the Xichen-1 well, therefore the study on the characteristics and mechanism of Halimeda carbonate sediments plays a pivotal role in the formation and construction of organic reefs in the South China Sea as well as oil and gas exploration.XU Hong ZHAO Xinwei EBERLI G.P.

15Thermal camouflage based on the phasechanging material GST显示文摘Camouflage technology has attracted growing interest for many thermal applications.Previous experimental demonstrations of thermal camouflage technology have not adequately explored the ability to continuously camouflage objects either at varying background temperatures or for wide observation angles.In this study,a thermal camouflage device incorporating the phase-changing material Ge2Sb2Te5(GST)is experimentally demonstrated.It has been shown that near-perfect thermal camouflage can be continuously achieved for background temperatures ranging from 30℃ to 50℃ by tuning the emissivity of the device,which is attained by controlling the GST phase change.The thermal camouflage is robust when the observation angle is changed from 0°to 60°.This demonstration paves the way toward dynamic thermal emission control both within the scientific field and for practical applications in thermal information.Yurui Qu Qiang Li Lu Cai Meiyan Pan Pintu Ghosh Kaikai Du Min Qiu 2018Light(Science & Applications)2018,7,1:3
16Vegetation Restoration in Response to Climatic and Anthropogenic Changes in the Loess Plateau, China显示文摘A thorough understanding of the vegetation succession in relation to both climatic changes and anthropogenic activities is vital for the formulation of adaptation strategies that address potential ecosystem challenges.Various climatic factors such as temperature,precipitation,and solar radiation,as well as anthropogenic factors such as ecological engineering and population migration,will affect the conditions for vegetation.However,the relationships among various factors remain unclear and the response of vegetation to climate change and anthropogenic activities in the Loess Plateau of China has not been well established.This study investigated the spatio-temporal characteristics and relationships between vegetation coverage and climatic factors in the Loess Plateau for the period of 1985–2015.Further analysis separated the anthropogenic and climatic factors on vegetation succession based on residual analysis.The results showed that the normalized difference vegetation index(NDVI)followed a significant upward trend with annual change rates of 0.15%during 1985–2015.The trend of human-induced NDVI increase was consistent with the spatial distribution of increasing forest areas in the eastern part of the Loess Plateau.Eco-restoration projects were the main driving factors that promoted vegetation coverage on the Loess Plateau.Furthermore,these results demonstrated that migrants to cities in the Loess Plateau could relieve ecological pressures and promote vegetation restoration.Therefore,the government should strive to increase population mobility and restore vegetation to sustain this particularly fragile ecological environment.QU Lulu HUANG Yunxin YANG Lingfan LI Yurui 2020Chinese Geographical Science2020,30,1:3

18Nickel(hydro)oxide/graphdiyne Catalysts for Efficient Oxygen Production Reaction显示文摘The transition metal-based materials have been regarded as promising electrocatalysts for oxygen evolution reaction(OER).However,achieving higher efficiency is largely limited by the valence states of metal species.Herein,different graphdiyne(GDY)-nickel composites were designed and synthesized[Ni(OH)_(2)/GDY,NiOOH/GDY,and NiO_(x)/GDY]as the electrocatalysts for OER.The NiO_(x)/GDY possessing the mixed valence states can drive the OER more efficiently than Ni(OH)_(2)/GDY and NiOOH/GDY.NiO_(x)/GDY gives the smallest overpotential of 310 mV at 10 mA/cm^(2) for OER,which is even superior to commercial RuO_(2)electrocatalyst.Experimental results reveal that not only the fast charge transfer induced by GDY but also the prominent roles of mixed Ni^(2+)/Ni^(3+) valence states boost the OER electrocatalytic performances.The presence of the mixed valence state was demonstrated to be helpful for the charge transfer,resulting in the enhancement of the catalytic activity.This work may provide a new direction to design and fabricate high-performance materials for OER and beyond.LUAN Xiaoyu XUE Yurui 2021Chemical Research in Chinese Universities2021,37,6:2

20Recent progress in developing efficient monolithic all-perovskite tandem solar cells显示文摘Organic–inorganic halide perovskites have received widespread attention thanks to their strong light absorption,long carrier diffusion lengths,tunable bandgaps,and low temperature processing.Single-junction perovskite solar cells(PSCs)have achieved a boost of the power conversion efficiency(PCE)from 3.8%to 25.2%in just a decade.With the continuous growth of PCE in single-junction PSCs,exploiting of monolithic all-perovskite tandem solar cells is now an important strategy to go beyond the efficiency available in single-junction PSCs.In this review,we first introduce the structure and operation mechanism of monolithic all-perovskite tandem solar cell.We then summarize recent progress in monolithic all-perovskite tandem solar cells from the perspectives of different structural units in the device:tunnel recombination junction,wide-bandgap top subcell,and narrow-bandgap bottom subcell.Finally,we provide our insights into the challenges and scientific issues remaining in this rapidly developing research field.Yurui Wang Mei Zhang Ke Xiao Renxing Lin Xin Luo Qiaolei Han Hairen Tan 2020Journal of Semiconductors2020,41,5:2
