| 1 | Full-colour nanoprint-hologram synchronous metasurface with arbitrary hue-saturationbrightness control显示文摘The colour gamut,a two-dimensional(2D)colour space primarily comprising hue and saturation(HS),lays the most important foundation for the colour display and printing industries.Recently,the metasurface has been considered a promising paradigm for nanoprinting and holographic imaging,demonstrating a subwavelength image resolution,a flat profile,high durability,and multi-functionalities.Much effort has been devoted to broaden the 2D HS plane,also known as the CIE map.However,the brightness(B),as the carrier of chiaroscuro information,has long been neglected in metasurface-based nanoprinting or holograms due to the challenge in realising arbitrary and simultaneous control of full-colour HSB tuning in a passive device.Here,we report a dielectric metasurface made of crystal silicon nanoblocks,which achieves not only tailorable coverage of the primary colours red,green and blue(RGB)but also intensity control of the individual colours.The colour gamut is hence extruded from the 2D CIE to a complete 3D HSB space.Moreover,thanks to the independent control of the RGB intensity and phase,we further show that a singlelayer silicon metasurface could simultaneously exhibit arbitrary HSB colour nanoprinting and a full-colour hologram image.Our findings open up possibilities for high-resolution and high-fidelity optical security devices as well as advanced cryptographic approaches. | Yanjun Bao Ying Yu Haofei Xu Chao Guo Juntao Li Shang Sun Zhang-Kai Zhou Cheng-Wei Qiu Xue-Hua Wang | 2019 | Light(Science & Applications)2019,8,1: | 25 |

| 3 | Determination of rock mass integrity coefficient using a non-invasive geophysical approach显示文摘Determination of rock mechanical parameters is the most important step in rock mass quality evaluation and has significant impacts on geotechnical engineering practice.Rock mass integrity coefficient(KV)is one of the most efficient parameters,which is conventionally determined from boreholes.Such approaches,however,are time-consuming and expensive,offer low data coverage of point measurements,require heavy equipment,and are hardly conducted in steep topographic sites.Hence,borehole approaches cannot assess the subsurface thoroughly for rock mass quality evaluation.Alternatively,use of geophysical methods is non-invasive,rapid and economical.The proposed geophysical approach makes useful empirical correlation between geophysical and geotechnical parameters.We evaluated the rock mass quality via integration between KV measured from the limited boreholes and inverted resistivity obtained from electrical resistivity tomography(ERT).The borehole-ERT correlation provided KV along various geophysical profiles for more detailed 2D/3D(two-/three-dimensional)mapping of rock mass quality.The subsurface was thoroughly evaluated for rock masses with different engineering qualities,including highly weathered rock,semi-weathered rock,and fresh rock.Furthermore,ERT was integrated with induced polarization(IP)to resolve the uncertainty caused by water/clay content.Our results show that the proposed method,compared with the conventional approaches,can reduce the ambiguities caused by inadequate data,and give more accurate insights into the subsurface for rock mass quality evaluation. | Muhammad Hasan Yanjun Shang Xuetao Yi Peng Shao Meng He | 2023 | Journal of Rock Mechanics and Geotechnical Engineering2023,15,6: | 1 |
| 4 | Two new reinforcement techniques applicable in high steep slopes along the Chengdu-Lhasa Highway, Southwest China显示文摘Anti-slide pile and anchoring hole are two types of reinforcement techniques popularly used in slope reinforcement. However, some defects of these two techniques are found in slope engineering practices. Utilizing higher tensile strength of pre-stressed structures, the authors devise two new types of slope reinforcement techniques, i.e. pre-stressed anchoring beam and pre-stressed anti-slide pile, in an attempt to overcome those defects of the existing techniques. These two new techniques are characterized by gathering multiple functions, e.g. engineering investigation, reinforcement, drainage, monitoring and strength supplement, so as to achieve high reinforcement efficiency, convenient checking, and higher ratio of function to cost. It is hoped that, if applying these two new techniques in remedies of landslide hazards along the Chengdu-Lhasa Highway, better reinforcement effects will be obtained. | YANG ZhifaZHU Jiewang ZHANG Luqing, CUI Peng, LI Xiao & SHANG Yanjun Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100029, China Institute of Mountain Hazards and Environment, Chinese Academy of Sciences and Ministry of Water Resources, Chengdu 610041, China | 2003 | Science China(Technological Sciences)2003,46,z1: | 1 |
| 5 | Identification of weathered troughs in granites for tunneling at Daya Bay reactor-neutrino experiment site显示文摘Weathered troughs are frequently encountered in granites.They can cause problems to tunneling in the rocks and have to be properly addressed.The structures or spatial shapes of weathered troughs were seldom clarified in the past.In this paper,four weathered troughs are identified by means of geophysical exploration,core drilling,logging,and in-situ stress measurement at Daya Bay reactor-neutrino experiment site in Shenzhen,China.The weathered troughs are exposed on the ground or partially covered by grass and soils,which will threaten the safety of horizontal tunneling at a shallow depth.High electrical resistivity(HER) method is adopted for its feasibility and practicality,in combination with field geological observation,ultrasonic televiewer in boreholes and in-situ stress measurement.By comparing the HER values of completely decomposed to fresh rocks,it is indicated that the HER values of weathered troughs in natural state are 0.4-100 ·m,and the in-situ stress is abnormally lower than those at upper and lower layers.Field investigations show that the depths of the four weathered troughs are 30-182 m,with bottom elevation over 10 m.The volume of each weathered trough is mostly over 1×10 6 m 3 in inverted conic form.The weathered troughs often occur in various kinds of landforms,such as ridges,gullies or gently dipping dish-like depression areas.Faults and boundaries of different granitic plutons as well as joints govern the formation,locations and strikes of these troughs under development. | Yanjun Shang Yongyue Shi Weijun Jin Daming Lin Fengbo Wu Wei Zhang | 2012 | Journal of Rock Mechanics and Geotechnical Engineering2012,4,2: | 1 |

| 8 | Metal-polyphenol-coordinated nanomedicines for Fe(II) catalyzed photoacoustic-imaging guided mild hyperthermia-assisted ferroustherapy against breast cancer显示文摘Ferroustherapy has gained great attention for anti-cancer treatment in recent years. Enlightened by temperature-mediated Fenton reaction in industrial waste water removal, we designed a iron-based polyphenol-coordinated nanomedicines for mild hyperthermia-assisted anti-cancer ferroustherapy. In brief, Fe-GA@BSA nanoparticles was synthesized by self-assembly and sorafenib(SRF) was loaded into Fe-GA@BSA to establish Fe-GA@BSA-SRF nanomedicines. The result nanomedicines can induce ferroptosis in cancer cells by accelerating Fenton reaction. And the photothermal effect of Fe-GA@BSA-SRF was used for mild hyperthermia-assisted ferroustherapy. The nanomedicines performs good anti-cancer therapeutic efficacy by inducing the production of ROS and inhibiting glutathione peroxidase 4(GPX4) expression in vitro and in vivo. Besides, the broad absorption of Fe-GA@BSA-SRF in near infrared region endows it with photoacoustic imaging ability. This study provides ideas about rational design on iron-based nanoparticles for anti-cancer ferroustherapy. | Xinying Yu Tongyi Shang Guodong Zheng Hailong Yang Yuwei Li Yanjun Cai Guoxi Xie Bin Yang | 2022 | Chinese Chemical Letters2022,33,4: | 1 |

| 10 | From the new Austrian tunneling method to the geoengineering condition evaluation and dynamic controlling method显示文摘The new Austrian tunneling method(NATM) is widely applied in design and construction of underground engineering projects. When the type and distribution of unfavorable geological bodies(UGBs)associated with their influences on geoengineering are complicated or unfortunately are overlooked, we should pay more attentions to internal features of rocks grades IV and V(even in local but mostly controlling zones). With increasing attentions to the characteristics, mechanism and influences of engineering construction-triggered geohazards, it is crucial to fully understand the disturbance of these geohazards on project construction. A reasonable determination method in construction procedure, i.e.the shape of working face, the type of engineering support and the choice of feasible procedure, should be considered in order to mitigate the construction-triggered geohazards. Due to their high sensitivity to groundwater and in-situ stress, various UGBs exhibit hysteretic nature and failure modes. To give a complete understanding on the internal causes, the emphasis on advanced comprehensive geological forecasting and overall reinforcement treatment is therefore of more practical significance. Comprehensive evaluation of influential factors, identification of UGB, and measures of discontinuity dynamic controlling comprises the geoengineering condition evaluation and dynamic controlling method. In a case of a cut slope, the variations of UGBs and the impacts of key environmental factors are presented,where more severe construction-triggered geohazards emerged in construction stage than those predicted in design and field investigation stages. As a result, the weight ratios of different influential factors with respect to field investigation, design and construction are obtained. | Yanjun Shang Kun Li Wantong He Chunbo Sheng | 2014 | Journal of Rock Mechanics and Geotechnical Engineering2014,6,4: | 1 |
| 11 | Coordinated development of land multi-function space: An analytical framework for matching the supply of resources and environment with the use of land space for ecological protection, agricultural production and urban construction显示文摘Based on the carrying capacity of the resources and the environment,this article defines the connotation of the land multifunctional space(LMFS)from three aspects,ecological protection,agricultural production and urban construction,in the new era of land space planning system.Moreover,a framework is constructed for the coordinated development of the multi-functional oriented space to match the use of land space(ULS)with the supply of resources and environment(SRE).Based on this,the technology and methods of comprehensive evaluation,dominance recognition,and matching relationship division functions of the use of land space(FULS)and functions of the supply of resources and environment(FSRE)are discussed.The advantageous functions of the use of land space(AFULS)and advantageous functions of the supply of resources and environment(AFSRE)are also identified in the study area.A LMFS coordinated development system integrating“function position-comprehensive partition-regulation strategy”is proposed.Through the empirical study of Shandong province,we found that,first,the FULS of ecological protection space in the province is mainly found in high value areas,and the FSRE is mainly in low value areas,which has certain complementarity in the space.The FULS of agricultural production space is mainly observed in high value areas,the FSRE is mainly in middle value areas,and the spatial distribution is balanced and staggered.The FULS of the urban construction space and the FSRE are mainly in middle values areas,and the spatial distribution is basically similar.Second,the FULS in the study area is dominated by the single advantage of agricultural production and urban construction,while the FSRE has a relatively balanced distribution of the advantages of ecological protection,single agricultural production and compound advantages of agricultural production and urban construction,and urban construction and ecological protection.The matching between the two is mainly at high and middle levels.Specifically,70%of the province’s land space still has a certain development and utilization potential,and 30%of ULS intensity is close to or exceeds the resource and environment carrying capacity.Third,considering the comprehensive impact of resource endowment,social and economic development and policy and institutional environment on different matching relationships,this paper constructs the land spatial development strategic pattern of“two screens-seven regions-multicore”positioning and“four regions-eight categories”hierarchical area of Shandong at the macro level,and puts forward a differentiated land space development strategy. | QU Yanbo ZHANG Yanjun WANG Shilei SHANG Ran ZONG Haining ZHAN Lingyun | 2023 | Journal of Geographical Sciences2023,33,2: | 1 |

| 14 | Deposition rate and interaction of human-riverine from height increase and permanent function of an 1180 years weir in Southeast China显示文摘This paper is to present an efficient approach to enriching the quantification model of human-riverine interactions and its anthropogenic impact by a retrospective study on one of the four most famous historical hydraulic projects in China,the Tuoshan Weir.It was constructed in 833 AD and had trajectories of natural resilience and hydraulic engineering maturity more than thousand years.Extensive historical data and maturation procedure of the hydraulic system were used judiciously to examine the spatial patterns of the long-term water conservancy system with agriculture,urbanization and civilization of Ningbo City in Zhejiang Province,Southeast China.Interaction framework is assessed from historical perspective and the deposition rate(DR)is calculated by analyzing the continuous increase of the Tuoshan Weir height.The results show that the declining DR during the 1180 years guaranteed the beneficial role the Tuoshan Weir played in spite of some negative river responses caused by the increase of sediment deposition and decrease of fresh water-retention capacity.The following up revamped workings and well matured hydraulic system around the Tuoshan Weir also contribute a lot to the designed mission of the weir.We conclude that hydraulic system maturation is very important for the proper function and life span of huge hydraulic projects. | SHANG YanJun PARK Hyeong-Dong YANG ZhiFa CHEN SiGuang LIN DaMing | 2014 | Science China Earth Sciences2014,57,2: | 0 |
| 15 | Back analysis of long-term stability of a 92 m span ancient quarrying cavern显示文摘Long-term stability of large-span caverns is a challenging issue for design and construction of underground rock engineering.The Heidong cavern group consisting of 21 caverns was constructed about 1400 years ago for quarrying in massive Cretaceous tuff.The cavern No.5 of the Heidong cavern group is characterized by an unsupported span up to 92 m,with the overburden thickness of only 3-25 m.To analyze its long-term stability,a detailed investigation was conducted to obtain its geometry and rock mass characteristics,and to monitor surrounding rock displacements.Based on field survey and laboratory tests,numerical simulations were performed using the finite difference code FLAC^(3D).The analysis results revealed that for the long-term stability of the cavern No.5,some major factors should be carefully considered,such as cavern excavation method in hard massive rocks,site investigation using trial pits,tools like short iron chisel and hammer for manual excavation,geometric dome roof,and waste rocks within abutment or on the floor.The highlights of the technologies obtained from this large-scale ancient underground project can provide reference for other similar project excavations in practice. | Yanjun Shang Lihui Li Wantong He Luqing Zhang Tianbin Li Zhifa Yang | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017,9,2: | 0 |
