1Three-dimensional artificial transpiration for efficient solar waste-water treatment显示文摘Solar steam generation is emerging as promising solar-energy conversion technology for potential applications in desalination, sterilization and chemical purification. Despite the recent use of photon management and thermal insulation, achieving optimum solar steam efficiency requires simultaneous minimization of radiation, convection and conduction losses without compromising light absorption.Inspired by the natural transpiration process in plants, here we report a 3 D artificial transpiration device with all three components of heat loss and angular dependence of light absorption minimized, which enables over 85% solar steam efficiency under one sun without external optical or thermal management. It is also demonstrated that this artificial transpiration device can provide a complementary path for waste-water treatment with a minimal carbon footprint, recycling valuable heavy metals and producing purified water directly from waste water contaminated with heavy metal ions.Xiuqiang Li Renxing Lin George Ni Ning Xu Xiaozhen Hu Bin Zhu Guangxin Lv Jinlei Li Shining Zhu Jia Zhu 2018National Science Review2018,5,1:27
2The revival of thermal utilization from the Sun: interfacial solar vapor generation显示文摘Since solar energy is the ultimate energy resource and a significant amount of global energy utilization goes through heat,there have been persistent efforts for centuries to develop devices and systems for solar–thermal conversion.Most recently,interfacial solar vapor generation,as an emerging concept of solar–thermal conversion,has gained significant attention for its great potentials in various fields such as desalination,sterilization,catalysis,etc.With the advances of rationally designed materials and structures and photon and thermal management at the nanoscale,interfacial solar vapor generation has demonstrated both thermodynamic and kinetical advantages over conventional strategies.In this review,we aim to illustrate the definition,mechanism and figures of merit of interfacial solar vapor generation,and to summarize the development progress of relevant materials and applications,as well as to provide a prospective view of the future.Lin Zhou Xiuqiang Li George W.

3Spectral tomographic imaging with aplanatic metalens显示文摘Tomography is an informative imaging modality that is usually implemented by mechanical scanning,owing to the limited depth-of-field(DOF)in conventional systems.However,recent imaging systems are working towards more compact and stable architectures;therefore,developing nonmotion tomography is highly desirable.Here,we propose a metalens-based spectral imaging system with an aplanatic GaN metalens(NA=0.78),in which large chromatic dispersion is used to access spectral focus tuning and optical zooming in the visible spectrum.After the function of wavelength-switched tomography was confirmed on cascaded samples,this aplanatic metalens is utilized to image microscopic frog egg cells and shows excellent tomographic images with distinct DOF features of the cell membrane and nucleus.Our approach makes good use of the large diffractive dispersion of the metalens and develops a new imaging technique that advances recent informative optical devices.Chen Chen Wange Song Jia-Wern Chen Jung-Hsi Wang Yu Han Chen Beibei Xu Mu-Ku Chen Hanmeng Li Bin Fang Ji Chen Hsin Yu Kuo Shuming Wang Din Ping Tsai Shining Zhu Tao Li 2019Light(Science & Applications)2019,8,1:12
4Promoting effect of microwave irradiation on CeO2-TiO2 catalyst for selective catalytic reduction of NO by NH3显示文摘In this work we prepared several CeO2-TiO2 catalysts for the NH3-SCR reactionusing co-precipitation with assistance of microwave irradiation.The catalytic NH3-SCR activities over CeO2-TiO2 catalysts at low temperatures are largely enhanced by the treatment of microwave irradiation,the operation temperature window is also broadened.For better understanding the promotion mechanism,the catalyst prepared by conventional co-precipitation with and without microwave irradiation treatment was characterized with H2-TPR,NH3-TPD,XPS,XRD and BET.Microwave irradiation treatment accelerates the crystallite rate of CeO2-TiO2 catalysts,and greatly enlarges their surface area by adjusting their microstructures.The resistance to SO2 and H2O is also improved via regulating the hierarchical pore structure by the microwave irradiation.Microwave irradiation treatment can also improve the redox property and increase the acid sites over the catalyst surfaces.The result of in situ DRIFTS suggests that the microwave irradiation treatment generates more Br?nsted acid sites on CeO2-TiO2-2 h catalyst,helpful in SCR reactions.XPS results show that after microwave irradiation on the CeO2-TiO2 catalysts,the surface demonstrates an elevated concentration of chemisorbed oxygen,consequently leading to better oxidation of NO to NO2.Additionally,the molar ratio of Ce3+/Ce4+has been elevated after being treated by microwave irradiation,a vital factor in enhancing the NH3-SCR activities.Jie Cheng Liyun Song Rui Wu Shining Li Yanming Sun Hongtai Zhu Wenge Qiu Hong He 2020Journal of Rare Earths2020,38,1:11

6Second-harmonic generation and manipulation in lithium niobate slab waveguides by grating metasurfaces显示文摘Nonlinear optical processes in waveguides play important roles in compact integrated photonics,while efficient coupling and manipulations inside the waveguides still remain challenging.In this work,we propose a new scheme for second-harmonic generation as well as beam shaping in lithium niobate slab waveguides with the assistance of well-designed grating metasurfaces atλ=1064 nm.By encoding the amplitude and phase into the holographic gratings,we further demonstrate strong functionalities of nonlinear beam shaping by the metasurface design,including dual focusing and Airy beam generation.Our approach would inspire new designs in the miniaturization and integration of compact multifunctional nonlinear light sources on chip.BIN FANG HANMENG LI SHINING ZHU TAO LI 2020Photonics Research2020,8,8:9
7Exploring the driving factors and their mitigation potential in global energy-related CO2 emission显示文摘In order to quantify the contribution of the mitigation strategies,an extended Kaya identity has been proposed in this paper for decomposing the various factors that influence the CO2 emission.To this end,we provided a detailed decomposition of the carbon intensity and energy intensity,which enables the quantification of clean energy development and electrification.The logarithmic mean divisia index(LMDI)has been applied to the historical data to quantify the contributions of the various factors affecting the CO2 emissions.Further,the global energy interconnection(GEI)scenario has been introduced for providing a systematic solution to meet the 2℃goal of the Paris Agreement.By combining LMDI with the scenario analysis,the mitigation potential of the various factors for CO2 emission has been analyzed.Results from the historical data indicate that economic development and population growth contribute the most to the increase in CO2 emissions,whereas improvement in the power generation efficiency predominantly helps in emission reduction.A numerical analysis,performed for obtaining the projected future carbon emissions,suggests that clean energy development and electrification are the top two factors that can decrease CO2 emissions,thus showing their great potential for mitigation in the future.Moreover,the carbon capture and storage technology serves as an important supplementary mitigation method.Zhiyuan Ma Shining Zhang Fangxin Hou Xin Tan Fengying Zhang Fang Yang Fei Guo 2020Global Energy Interconnection2020,3,5:9
8A bioactive injectable self-healing anti-inflammatory hydrogel with ultralong extracellular vesicles release synergistically enhances motor functional recovery of spinal cord injury显示文摘The repair and motor functional recovery after spinal cord injury(SCI)remains a worldwide challenge.The inflammatory microenvironment is one of main obstacles on inhibiting the recovery of SCI.Using mesenchymal stem cells(MSCs)derived extracellular vesicles to replace MSCs transplantation and mimic cell paracrine secretions provides a potential strategy for microenvironment regulation.However,the effective preservation and controlled release of extracellular vesicles in the injured spinal cord tissue are still not satisfied.Herein,we fabricated an injectable adhesive anti-inflammatory F127-polycitrate-polyethyleneimine hydrogel(FE)with sustainable and long term extracellular vesicle release(FE@EVs)for improving motor functional recovery after SCI.The orthotopic injection of FE@EVs hydrogel could encapsulate extracellular vesicles on the injured spinal cord,thereby synergistically induce efficient integrated regulation through suppressing fibrotic scar formation,reducing inflammatory reaction,promoting remyelination and axonal regeneration.This study showed that combining extracellular vesicles into bioactive multifunctional hydrogel should have great potential in achieving satisfactory locomotor recovery of central nervous system diseases.Chenggui Wang Min Wang Kaishun Xia Jingkai Wang Feng Cheng Kesi Shi Liwei Ying Chao Yu Haibin Xu Shining Xiao Chengzhen Liang Fangcai Li Bo Lei Qixin Chen 2021Bioactive Materials2021,6,8:9
9Research on Properties of Carbon Fiber/Epoxy Resin Composite Material by Microwave Curing显示文摘Microwave irradiation was used to reduce the curing time of carbon fiber/epoxy resin composite material.The properties of carbon fiber/epoxy resin composite material under microwave curing were investigated by thermogravimetry(TG),dynamic mechanical analysis(DMA),impact strength test and scanning electron microscope(SEM).The results show that composite materials patch have high thermal stability after microwave curing.The initial degradation temperature is 330.9℃,the maximum thermal decomposition rate is at 368.1℃.When the layer of composite materials patchis 4 layers,the dynamic mechanical properties are the best after microwave curing.The initial storage modulus is 43.2 GPa,increased 28.3 GPa and 27.1 GPa than 3 layers and 5 layers,the glass transition temperature(Tg)is 67.48℃,increased about 12 ℃than 3 layers and 5 layers.Microwave curing can significantly improve the infiltration capacity of epoxy resin,enhance interfacial bonding,and increase the impact strength of composite patch.Under microwave curing,the impact strength of 3,4,5-layers composite material patches increases 35.9%,6.4% and 15.1%,respectively than heating curing.The SEM analysis of impact fracture surface shows that microwave curing can improve the interface of carbon fiber and epoxy resin.Sun Xiaofeng Ma Shining Liu Hongwei 2012稀有金属材料与工程2012,41,S1:7
10Metalens-integrated compact imaging devices for wide-field microscopy显示文摘Metasurfaces have demonstrated unprecedented capabilities in manipulating light with ultrathin and flat architectures.Although great progress has been made in the metasurface designs and function demonstrations,most metalenses still only work as a substitution of conventional lenses in optical settings,whose integration advantage is rarely manifested.We propose a highly integrated imaging device with silicon metalenses directly mounted on a complementary metal oxide semiconductor image sensor,whose working distance is in hundreds of micrometers.The imaging performances including resolution,signal-to-noise ratio,and field of view(FOV)are investigated.Moreover,we develop a metalens array with polarization-multiplexed dual-phase design for a wide-field microscopic imaging.This approach remarkably expands the FOV without reducing the resolution,which promises a non-limited space-bandwidth product imaging for wide-field microscopy.As a result,we demonstrate a centimeter-scale prototype for microscopic imaging,showing uniqueness of meta-design for compact integration.Beibei Xu Hanmeng Li Shenglun Gao Xia Hu Cheng Yang Chen Chen Feng Yan Shining Zhu Tao Li 2020Advanced Photonics2020,2,6:6
11Quasi-phase-matching-division multiplexing holography in a three-dimensional nonlinear photonic crystal显示文摘Nonlinear holography has recently emerged as a novel tool to reconstruct the encoded information at a new wavelength,which has important applications in optical display and optical encryption.However,this scheme still struggles with low conversion efficiency and ineffective multiplexing.In this work,we demonstrate a quasi-phasematching(QPM)-division multiplexing holography in a three-dimensional(3D)nonlinear photonic crystal(NPC).3D NPC works as a nonlinear hologram,in which multiple images are distributed into different Ewald spheres in reciprocal space.The reciprocal vectors locating in a given Ewald sphere are capable of fulfilling the complete QPM conditions for the high-efficiency reconstruction of the target image at the second-harmonic(SH)wave.One can easily switch the reconstructed SH images by changing the QPM condition.The multiplexing capacity is scalable with the period number of 3D NPC.Our work provides a promising strategy to achieve highly efficient nonlinear multiplexing holography for high-security and high-density storage of optical information.Pengcheng Chen Chaowei Wang Dunzhao Wei Yanlei Hu Xiaoyi Xu Jiawen Li Dong Wu Jianan Ma Shengyun Ji Leran Zhang Liqun Xu Tianxin Wang Chuan Xu Jiaru Chu Shining Zhu Min Xiao Yong Zhang 2021Light(Science & Applications)2021,10,8:5
12Electrically controllable laser frequency combs in graphene-fibre microresonators显示文摘Laser frequency combs emitting ultrafast pulses of light,at equidistantly discrete frequencies,are cornerstones of modern information networks.In recent years,the generation of soliton combs in microcavities with ultrahighquality factors has established microcombs as out-oflaboratory tools.However,the material and geometry of a laser cavity,which determine comb formation,are difficult to electrically tune.Such dynamic control can further enrich the diversity of comb outputs and help to actively stabilize them.Chenye Qin Kunpeng Jia Qianyuan Li Teng Tan Xiaohan Wang Yanhong Guo Shu-Wei Huang Yuan Liu Shining Zhu Zhenda Xie Yunjiang Rao Baicheng Yao 2020Light(Science & Applications)2020,9,1:5
13Heterogeneously integrated,superconducting silicon-photonic platform for measurementdevice-independent quantum key distribution显示文摘Integrated photonics provides a route to both miniaturization of quantum key distribution(QKD)devices and enhancing their performance.A key element for achieving discrete-variable QKD is a singlephoton detector.It is highly desirable to integrate detectors onto a photonic chip to enable the realization of practical and scalable quantum networks.We realize a heterogeneously integrated,superconducting silicon-photonic chip.Harnessing the unique high-speed feature of our optical waveguide-integrated superconducting detector,we perform the first optimal Bell-state measurement(BSM)of time-bin encoded qubits generated from two independent lasers.The optimal BSM enables an increased key rate of measurement-device-independent QKD(MDI-QKD),which is immune to all attacks against the detection system and hence provides the basis for a QKD network with untrusted relays.Together with the timemultiplexed technique,we have enhanced the sifted key rate by almost one order of magnitude.With a 125-MHz clock rate,we obtain a secure key rate of 6.166 kbps over 24.0 dB loss,which is comparable to the state-of-the-art MDI-QKD experimental results with a GHz clock rate.Combined with integrated QKD transmitters,a scalable,chip-based,and cost-effective QKD network should become realizable in the near future.Xiaodong Zheng Peiyu Zhang Renyou Ge Liangliang Lu Guanglong He Qi Chen Fangchao Qu Labao Zhang Xinlun Cai Yanqing Lu Shining Zhu Peiheng Wu Xiao-Song Ma 2021Advanced Photonics2021,3,5:5

15Light rays and waves on geodesic lenses显示文摘Starting from well-known absolute instruments that provide perfect imaging, we analyze a class of rotationally symmetric compact closed manifolds, namely, geodesic lenses. We demonstrate with a numerical method that light rays confined on geodesic lenses form closed trajectories, and that for optical waves, the spectrum of a geodesic lens is(at least approximately) degenerate and equidistant. Moreover, we fabricate two geodesic lenses in micrometer and millimeter scales and observe curved light rays along the geodesics. Our experimental setup may offer a new platform to investigate light propagation on curved surfaces.Lin Xu Xiangyang Wang Tomas Tyc Chong Sheng Shining Zhu Hui Liu HUANYANG CHEN 2019Photonics Research2019,7,11:3
16Multi-Gradient Routing Protocol for Wireless Sensor Networks显示文摘Sensor networks tend to support different traffic patterns since more and more emerging applications have diverse needs. We present MGRP, a Multi-Gradient Routing Protocol for wireless sensor networks, which is fully distributed and efficiently supports endto-end, one-to-many and many-to-one traffic patterns by effectively construct and maintain a gradient vector for each node. We further combine neighbor link estimation with routing information to reduce packet exchange on network dynamics and node failures. We have implemented MGRP on Tiny OS and evaluated its performance on real-world testbeds. The result shows MGRP achieves lower end-to-end packet delay in different traffic patterns compared to the state of the art routing protocols while still remains high packet delivery ratio.Ying Qiu Shining Li Zhigang Li Yu Zhang Zhe Yang 2017China Communications2017,14,3:3
17Metamaterials: artificial materials beyond nature显示文摘Research in advanced materials is continuously driving modern technologies forward.For example,semiconductors have laid the foundation for today’s electronics industry.While constantly searching for new materials in nature,another approach is to craft novel composite materials beyond the naturally available properties.This is accomplished by directly designingShining Zhu Xiang Zhang 2018National Science Review2018,5,2:3
18Surface nanostructure formation mechanism of 45 steel induced by supersonic fine particles pombarding显示文摘By means of supersonic fine particles bombarding (SFPB),a nanostructured surface layer up to 15 μm was fabricated on a 45 steel plate with ferrite and pearlite phases. To reveal the grain refinement mechanism of SFPB-treated 45 steel,microstructure features of various sections in the treated surface were systematically characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Grain size increases with an increase of depth from the treated surface. Plastic deformation and grain refinement processes are accompanied by an increase in strain. Plastic deformation in the proeutectoid ferrite phases has precedence over the pearlite phases. Grain refinement in the ferrite phases involves: the onset of dis-location lines (Dls),dislocation tangles (DTs) and dense dislocation walls (DDWs) in the original grains; the formation of fine la-mellar and roughly equiaxed cells separated by DDWs; by dislocation annihilation and rearrangement,the transformation of DDWS into subboundaries and boundaries and the formation of submicron grains or subgrains; the successive subdivision of grains to finer and finer scale,resulting in the formation of highly misoriented nano-grains. By contrast,eutectoid cementite phase accommodated strain in a sequence as follows: onset of elongated,bended and shear deformation under deformation stress of ferrites,short and thin cementites with a width of about 20-50 nm and discontinuous length were formed. Shorter and thinner cementites were developed into ultra-fine pieces under the action of high density dislocation and strains. At the top surface,some cementites were decomposed under severe plastic deformation. Experimental evidences and analysis indicate that surface nanocrystallization of 45 steel results from dislocation activities,high strains and high strain rate are necessary for the formation of nanocrystallites.Dema Ba Shining Ma Changqing Li Fanjun Meng 2008Journal of University of Science and Technology Beijing2008,15,5:3
19Periodically poled LiNbO3 crystals from 1D and 2D to 3D显示文摘A periodically-poled LiNbO3(PPLN) crystal features space-dependent second-order nonlinear coefficients, which is one of the most important materials to effectively control nonlinear optical interactions through quasi-phase matching(QPM). By using electric-field poling method, 1D and 2D PPLN crystals have been successfully fabricated for laser frequency conversion, quantum light sources, nonlinear beam shaping and nonlinear optical imaging. Recently, femtosecond laser engineering technique is utilized to prepare 3D domain structures inside LiNbO3 crystal, which provides a promising platform to control nonlinear interacting waves in 3D configuration. After 40 years of developments, PPLN crystals still have exciting prospects in fundamental researches and practical applications for integrated photonic chip, quantum information processing,and so on.WANG TianXin CHEN PengCheng XU Chuan ZHANG Yong WEI DunZhao HU XiaoPeng ZHAO Gang XIAO Min ZHU ShiNing 2020Science China(Technological Sciences)2020,63,7:3
20Transformation optics based on metasurfaces显示文摘The development of transformation optics and metamaterials provides a new paradigm for efficiently controlling electromagnetic waves. It is well known that the metamaterial is a novel artificial material with periodic structure, and the unit geometric size and distance between the units are much smaller than the working wavelength. Therefore, for an electromagnetic wave, a macroscopic system comprising these sub-wavelength units can be regarded as a novelty artificial material with a different permittivity, permeability and refractive index compared to the original material. Furthermore, these electromagnetic parameters of the artificial material can be freely manipulated by modifying their unit structure, especially for a material that does not exist in nature. Among these materials, negative refractive index materials have been widely reported. For a negative refractive index material, when light is incident on its interface, the incident and refracted light are distributed on the same side of the surface normal, rather than on both sides as typical materials do. However, the field of transformation optics proposes the concept that the propagation of an electromagnetic wave in curved spacetime is identical in inhomogeneous and anisotropic optical mediums.Chong Sheng Hui Liu Shining Zhu 2019Science Bulletin2019,64,12:3
