| 2 | Directly patterned substrate-free plasmonic “nanograter” structures with unusual Fano resonances显示文摘The application of three-dimensional(3D)plasmonic nanostructures as metamaterials(MMs),nano-antennas,and other devices faces challenges in producing metallic nanostructures with easily definable orientations,sophisticated shapes,and smooth surfaces that are operational in the optical regime and beyond.Here,we demonstrate that complex 3D nanostructures can be readily achieved with focused-ion-beam irradiation-induced folding and examine the optical characteristics of plasmonic“nanograter”structures that are composed of free-standing Au films.These 3D nanostructures exhibit interesting 3D hybridization in current flows and exhibit unusual and well-scalable Fano resonances at wavelengths ranging from 1.6 to 6.4 mm.Upon the introduction of liquids of various refractive indices to the structures,a strong dependence of the Fano resonance is observed,with spectral sensitivities of 1400 nm and 2040 nm per refractive index unit under figures of merit of 35.0 and 12.5,respectively,for low-order and high-order resonance in the near-infrared region.This work indicates the exciting,increasing relevance of similarly constructed 3D free-standing nanostructures in the research and development of photonics and MMs. | Ajuan Cui Zhe Liu Jiafang Li Tiehan H Shen Xiaoxiang Xia Zhiyuan Li Zhijie Gong Hongqiang Li Benli Wang Junjie Li Haifang Yang Wuxia Li Changzhi Gu | 2015 | Light(Science & Applications)2015，4，1： | 8 |
| 3 | Effects of Anthropogenic Disturbance on Sediment Organic Carbon Mineralization Under Different Water Conditions in Coastal Wetland of a Subtropical Estuary显示文摘The changes in soil organic carbon(C) mineralization as affected by anthropogenic disturbance directly determine the role of soils as C source or sink in the global C budget. The objectives of this study were to investigate the effects of anthropogenic disturbance(aquaculture pond, pollutant discharge and agricultural activity) on soil organic C mineralization under different water conditions in the Minjiang River estuary wetland, Southeast China. The results showed that the organic C mineralization in the wetland soils was significantly affected by human disturbance and water conditions(P < 0.001), and the interaction between human disturbance activities and water conditions was also significant(P < 0.01). The C mineralization rate and the cumulative mineralized carbon dioxide-carbon(CO_2-C)(at the 49th day) ranked from highest to lowest as follows: Phragmites australis wetland soil > aquaculture pond sediment > soil near the discharge outlet > rice paddy soil. This indicated that human disturbance inhibited the mineralization of C in soils of the Minjiang River estuary wetland, and the inhibition increased with the intensity of human disturbance. The data for cumulative mineralized CO_2-C showed a good fit(R^2 > 0.91) to the first-order kinetic model C_t = C_0(1 – exp(–kt)). The kinetic parameters C_0, k and C_0 k were significantly affected by human disturbance and water conditions. In addition, the total amount of mineralized C(in 49 d) was positively related to C_0, C_0 k and electrical conductivity of soils. These findings indicated that anthropogenic disturbance suppressed the organic C mineralization potential in subtropical coastal wetland soils, and changes of water pattern as affected by human activities in the future would have a strong influence on C cycling in the subtropical estuarine wetlands. | MOU Xiaojie LIU Xingtu SUN Zhigao TONG Chuan HUANG Jiafang WAN Siang WANG Chun WEN Bolong | 2018 | Chinese Geographical Science2018，28，3： | 4 |
| 4 | Variation of Thornthwaite Moisture Index in Hengduan Mountains, China显示文摘The Thornthwaite moisture index, an index of the supply of water(precipitation) in an area relative to the climatic demand for water(potential evapotranspiration), was used to examine the spatial and temporal variation of drought and to verify the influence of environmental factors on the drought in the Hengduan Mountains, China. Results indicate that the Thornthwaite moisture index in the Hengduan Mountains had been increasing since 1960 with a rate of 0.1938/yr. Annual Thornthwaite moisture index in Hengduan Mountains was between –97.47 and 67.43 and the spatial heterogeneity was obvious in different seasons. Thornthwaite moisture index was high in the north and low in the south, and the monsoon rainfall had a significant impact on its spatial distribution. The tendency rate of Thornthwaite moisture index variation varied in different seasons, and the increasing trends in spring were greater than that in summer and autumn. However, the Thornthwaite moisture index decreased in winter. Thornthwaite moisture index increased greatly in the north and there was a small growth in the south of Hengduan Mountains. The increase of precipitation and decrease of evaporation lead to the increase of Thornthwaite moisture index. Thornthwaite moisture index has strong correlation with vegetation coverage. It can be seen that the correlation between Normalized Difference Vegetation Index(NDVI) and Thornthwaite moisture index was positive in spring and summer, but negative in autumn and winter. Correlation between Thornthwaite moisture index and relative soil relative moisture content was positive in spring, summer and autumn, but negative in winter. The typical mountainous terrain affect the distribution of temperature, precipitation, wind speed and other meteorological factors in this region, and then affect the spatial distribution of Thornthwaite moisture index. The unique ridge-gorge terrain caused the continuity of water-heat distribution from the north to south, and the water-heat was stronger than that from the east to west part, and thus determined the spatial distribution of Thornthwaite moisture index. The drought in the Hengduan Mountains area is mainly due to the unstable South Asian monsoon rainfall time. | ZHU Guofeng QIN Dahe TONG Huali LIU Yuanfeng LI Jiafang CHEN Dongdong WANG Kai HU Pengfei | 2016 | Chinese Geographical Science2016，26，5： | 4 |
| 5 | Immune fluorescence test strips based on quantum dots for rapid and quantitative detection of carcino-embryonic antigen显示文摘At present,many researchers focused on the point-of-care testing(POCT),a method of disease markers detection without large-scale instruments and specialized persons.However,most POCT diagnostic methods were suffered from poor detection sensitivity or inefficiency in quantitative detection.Herein,we developed a newly QD-immune fluorescence test strips(QD-IFTS) based on quantum dots(QDs) as the fluorescence nanocarrier to prepare the immune fluorescence probes in the classical immunochromatography detection system for sensing carcino-embryonic antigen(CEA),a kind of glycoprotein produced by intestinal tissue and a broad spectrum of tumor marker for cancer diagnosis.And we designed a homemade strips fluorescence reader for detection of fluorescence intensity of QDs on the QD-IFTS.Under the optimized reaction conditions,chromatographic time of the newly QD-IFTS was only25 min,sample volume of the newly QD-IFTS was only 40 m L and the LOD of the newly QD-IFTS was 0.72 ng/m L.In addition,the efficiency and robustness of the newly QD-IFTS were confirmed by successfully application in 300 clinical serum samples,and the results revealed great potential in clinical POCT of other biomarkers. | Yudong Wu Weipan Peng Qian Zhao Jiafang Piao Bo Zhang Xiaoli Wu Hanjie Wang Zhihong Shi Xiaoqun Gong Jin Chang | 2017 | Chinese Chemical Letters2017，28，9： | 3 |
| 6 | Geomorphological site classification for the Fujian province显示文摘Geomorphological classification of the Fujian province was done based on remote-sensing imaging, digital elevation maps, and slope gradient data acquired by ArcGIS9.2. The engineering geological units in the Fujian province were divided into five types by the geomorphologic shape and genesis. The relationship among geomorphological type, engineering geological unit, and site category was determined using engineering geological data and site category data. Then, after making a preliminary site classification adjusted by drill hole data, the site was classified into four types: I0, I1, II, and III according to site classification standards of equivalent shear-wave velocity and overburden thickness. The results showed that the site categories in the Fujian province mainly consist of type II, which accounts for85.26 % of the land area. The percentage of I0was the smallest, which accounts for only 2.44 % of the total area. | Yao Ke Shichun Zheng Zhao Huang Shanxiong Wang Jiafang Huang | 2013 | Earthquake Science2013，26，1： | 2 |

| 8 | Reconfigurable nano-kirigami metasurfaces by pneumatic pressure显示文摘Tunable/reconfigurable metasurfaces that can actively control electromagnetic waves upon external stimuli are of great importance for practical applications of metasurfaces.Here,we demonstrate a reconfigurable nano-kirigami metasurface driven by pneumatic pressure operating in the near-infrared wavelength region.The metasurfaces consist of combined Archimedean spirals and are fabricated in a free-standing gold/silicon nitride nanofilm by employing focused ion beam(FIB)lithography.The deformable spirals are instantly transformed from two dimensional(2 D)to three-dimensional(3 D)by the FIB-based nano-kirigami process.The 2 D–to–3 D transformation induces a dramatic irreversible change of the plasmonic quadruple modes and results in significant modulation in reflection by 137%.The suspended porous nano-kirigami metasurface is further integrated with an optofluidics device,with which the optical resonance is reversibly modulated by the pneumatic pressure.This work provides a strategy for tunable/reconfigurable metasurfaces,which are useful to build a promising lab-ona-chip platform for microfluidics,biological diagnostics,chemical sensing,and pressure monitoring. | Shanshan Chen Wei Wei Zhiguang Liu Xing Liu Shuai Feng Honglian Guo Jiafang Li | 2020 | Photonics Research2020，8，7： | 2 |

| 16 | Cascaded multilayer nano-kirigami for extensible 3D nanofabrication and visible light manipulation显示文摘Nano-kirigami enables direct and versatile shape transformations from two-dimensional predesigns to threedimensional(3 D)architectures in microscale/nanoscale.Here a new and extensible strategy for cascaded multilayer nano-kirigami is demonstrated in a gold/silicon nitride(Au/SiN)bilayer nanofilm for 3 D nanofabrication and visible light manipulation.By employing a focused ion-beam-based Boolean irradiation,rich 3 D shape transformation and nested multilayer nanostructures are precisely manufactured,which are well reproduced by developing a modified mechanical model.Based on the multilayer and deformable features of the nano-kirigami structures,potentials in manipulating the phase and intensity of visible light are explored.The developed new nano-kirigami strategies,as well as the novel exotic 3 D nanostructures,could be helpful to build a novel platform for 3 D nanofabrication and find potential applications in microelectromechanical/nanoelectromechanical systems,holographic display,plasmonics,nanophotonics,biophotonics,etc. | YU HAN ZHIGUANG LIU SHANSHAN CHEN JUAN LIU YONGTIAN WANG AND JIAFANG LI | 2020 | Photonics Research2020，8，9： | 1 |

| 18 | Microscopic and macroscopic manipulation of gold nanorod and its hybrid nanostructures[Invited]显示文摘Gold nanorods(GNRs)have potential applications ranging from biomedical sciences and emerging nanophotonics.In this paper,we will review some of our recent studies on both microscopic and macroscopic manipulation of GNRs.Unique properties of GNR nanoparticles,such as efficient surface plasmon amplifications effects,are introduced.The stable trapping,transferring,positioning and patterning of GNRs with nonintrusive optical tweezers will be shown.Vector beams are further employed to improve the trapping performance.On the other hand,alignment of GNRs and their hybrid nanostructures will be described by using a film stretch method,which induces the anisotropic and enhanced absorptive nonlinearities from aligned GNRs.Realization and engineering of polarized emission from aligned hybrid GNRs will be further demonstrated,with relative excitation–emission efficiency significantly enhanced.Our works presented in this review show that optical tweezers possess great potential in microscopic manipulation of metal nanoparticles and macroscopic alignment of anisotropic nanoparticles could help the macroscopic samples to flexibly represent the plasmonic properties of single nanoparticles for fast,cheap,and high-yield applications. | Jiafang Li Honglian Guo Zhi-Yuan Li | 2013 | Photonics Research2013，1，1： | 1 |

| 20 | Hydrothermal evolution and source of metallogenic materials of Beiya Au polymetallic deposit,western Yunnan,China显示文摘The Beiya porphyry-skarn gold-polymetallic deposit is one of the largest gold deposits in China and it also contains significant amounts of silver and base metals.The ore-bearing monzonitic granite porphyry occurs as a stock,of which the skarn type gold-copper-iron ore bodies are controlled by the contact zone between alkali-rich monzonitic granite porphyry and the limestone,and the gold-silver polymetallic mineralization is controlled by interlayer structure.Alteration and mineralization occur around the intrusion and exterior of monzonitic granite porphyry.Ore mineral formation sequence is as follows:skarn minerals→magnetite→pyrite→chalcopyrite/bornite+pyrite+gold→pyrite+galena+gold(silver).Petrographic studies of fluid inclusions indicate that the following types of inclusions exist in the pre-mineralization quartz-pyrite stage:gas-liquid two-phase inclusions(L-type),three-phase inclusions with daughter minerals(D-type)and gas-rich inclusions(V-type).The colorless transparent quartz in the main gold-chalcopyrite-pyrite stage mainly consists of L-type and V-type inclusions,whereas the inclusions in the late gold-silver-galena stage are mainly L-type.The evolution of ore-forming fluids shows a trend from high temperature,high salinity to medium-low temperature and low salinity.Medium-low density fluids play a dominant role in mineral component migration and transportation.Fluid cooling and boiling are the main mechanisms of gold-copper precipitation,while the involvement of atmospheric water and pH reduction are the main mechanisms of gold-silver polymetallic precipitation.The fluids in the quartz-pyrite stage before mineralization and the main gold-chalcopyrite-pyrite stage are dominated by magmatic water,while in the gold-silver-galena stage the fluids are dominated by atmospheric water.Isotope tracers show that S and Pb are mainly derived from monzonitic granite porphyry,not from limestone of the Beiya Formation. | DENG Jiafang SUN Fengyue XIN Wei XU Zhihe PAN Zhongcui WU Dongqian TIAN Nan | 2020 | Global Geology2020，23，2： | 1 |
