| 1 | Nanoplasmonic 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 | 2015 | Light(Science & Applications)2015，4，1： | 19 |
| 2 | Nanowire-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 | 2014 | Light(Science & Applications)2014，3，1： | 8 |
| 3 | Graphdiyne-based metal atomic catalysts for synthesizing ammonia显示文摘Development of novel catalysts for nitrogen reduction at ambient pressures and temperatures with ultrahigh ammonia(NH_(3))yield and selectivity is challenging.In this work,an atomic catalyst with separated Pd atoms on graphdiyne(Pd-GDY)was synthesized,which shows fascinating electrocatalytic properties for nitrogen reduction.The catalyst has the highest average NH_(3)yield of 4.45±0.30 mgNH_(3)mg Pd^(-1)h^(-1),almost tens of orders larger than for previously reported catalysts,and 100%reaction selectivity in neutral media.Pd-GDY exhibits almost no decreases in NH_(3)yield and Faradaic efficiency.Density functional theory calculations show that the reaction pathway prefers to perform at the(Pd,C1,C2)active area because of the strongly coupled(Pd,C1,C2),which elevates the selectivity via enhanced electron transfer.By adjusting the p–d coupling accurately,reduction of self-activated nitrogen is promoted by anchoring atom selection,and side effects are minimized. | Huidi Yu Yurui Xue Lan Hui Chao Zhang Yan Fang Yuxin Liu Xi Chen Danyan Zhang Bolong Huang Yuliang Li | 2021 | National Science Review2021，8，8： | 2 |

| 8 | Responses of the East Component of Beijing GNSS Continuous Observation Stations to the 2011 Japan M_W 9.0 Earthquake显示文摘Several new demands have been put forward for the application of the Beijing continuous GNSS observations due to some particular reasons,such as the limited coverage of the observation network,the different construction and management criterion executed by different units and the intense interference resulting from human activity. In this paper,necessary processing of data is carried out, including more accurate calculation,corrections to the replacement,outliers and relocation of equipment,and elimination of linear trends in the E-component for every station. The E-components of the 16 available stations showed a lower sawtooth wave anomaly( s lowly westward propagating) b efore the2011 Tohoku M W9. 0 earthquake,a coseismic step rebound( rapid eastward propagating)and a post-seismic Ω-shaped recovery. These steps constituted a complete earthquake process which was rarely seen before in the GNSS observations and provides a good example for further study. Moreover, t he rapid eastward propagating during the earthquake is not influenced by the size of the given normal values,which may play a significant role in earthquake forecasting and early warning. | Wu Peizhi Sun Jianbao Xu Ping Xing Chengqi Hu Leyin Liang Fang Huang Yurui Shi Yufang Ji Hong | 2015 | Earthquake Research in China2015，29，2： | 0 |
| 9 | Spatiotemporal Pattern of Cultivated Land Pressure and Its Influencing Factors in the Huaihai Economic Zone, China显示文摘Cultivated land pressure represents a direct reflection of grain security. Existing relevant studies rarely approached the spatiotemporal pattern of cultivated land pressure or the spatial heterogeneity of its influencing factors from the level of economic zones.Taking the Huaihai Economic Zone(HEZ), China for case analysis, this study investigated the spatiotemporal pattern of cultivated land pressure in diverse periods from 2000 to 2018 based on a modified cultivated land pressure index and spatial correlation models. On this basis, it explored the influencing factors of the spatial differentiation of cultivated land pressure in the late stage of the study using geographical detector as well as multi-scale geographically weighted regression model. The results indicated that: 1) in the study period, the global cultivated land pressure index of the study area decreased gradually, but cultivated land pressure increased locally in a significant way, especially in the central and southern Shandong Province;2) the spatial pattern of cultivated land pressure manifested global clustering features. Hot and secondary-hot spots presented a narrowing and clustering trend, whereas cold and secondary-cold spots manifested a spreading and clustering trend;3) average slope, the proportion of non-grain crops, population urbanization rate, and multiple cropping index have significant effects on the spatial differentiation of cultivated land pressure. The former three factors were positively correlated with cultivated land pressure, and the last factor was negatively correlated with cultivated land pressure;and 4) the amount of cultivated land has increased in the central and southern Shandong Province through land consolidation which, nonetheless, failed to improve the grain production. In regards to major grain producing areas similar to the HEZ in China, the authors suggest that great importance should be given to the balance of the quality and quantity of cultivated land, the optimization of agricultural production factors and the rational control of non-grain crops, thus providing a powerful guarantee for grain security in China. | LI Yi FANG Bin LI Yurui FENG Weilun YIN Xu | 2023 | Chinese Geographical Science2023，33，2： | 0 |
