| 2 | Terahertz surface plasmonic waves: a review显示文摘Terahertz science and technology promise many cutting-edge applications.Terahertz surface plasmonic waves that propagate at metal–dielectric interfaces deliver a potentially effective way to realize integrated terahertz devices and systems.Previous concerns regarding terahertz surface plasmonic waves have been based on their highly delocalized feature.However,recent advances in plasmonics indicate that the confinement of terahertz surface plasmonic waves,as well as their propagating behaviors,can be engineered by designing the surface environments,shapes,structures,materials,etc.,enabling a unique and fascinating regime of plasmonic waves.Together with the essential spectral property of terahertz radiation,as well as the increasingly developed materials,microfabrication,and time-domain spectroscopy technologies,devices and systems based on terahertz surface plasmonic waves may pave the way toward highly integrated platforms for multifunctional operation,implementation,and processing of terahertz waves in both fundamental science and practical applications.We present a review on terahertz surface plasmonic waves on various types of supports in a sequence of properties,excitation and detection,and applications.The current research trend and outlook of possible research directions for terahertz surface plasmonic waves are also outlined. | Xueqian Zhang Quan Xu Lingbo Xia Yanfeng Li Jianqiang Gu Zhen Tian Chunmei Ouyang Jiaguang Han Weili Zhang | 2020 | Advanced Photonics2020，2，1： | 7 |
| 3 | Plasmon-induced transparency in terahertz metamaterials显示文摘The quantum phenomena of electromagnetically induced transparency(EIT)or plasmonic analogue of electromagnetically induced transparency(PIT)can be mimicked in the classical resonators,leading to a unique way to explore the coherent coupling mechanism in metamaterial systems.Various metamaterial structures have been proposed to excite and manipulate the PIT efect with flexibility and performance with geometry-controllable,polarization-independent,broadband-transparency and active-modulated characteristics.These in turn promise the fascinating functionalities and applications of the PIT efects,such as slow-light components,nonlinear devices and high-sensitivity sensors.Here,we present a review on the progress in developing the PIT efect in terahertz metamaterials over the past few years. | JING HuiHui ZHU ZhiHua ZHANG XueQian GU JianQiang TIAN Zhen OUYANG ChunMei HAN JiaGuang ZHANG WeiLi | 2013 | Science China(Information Sciences)2013，56，12： | 5 |
| 4 | Active terahertz beam steering based on mechanical deformation of liquid crystal elastomer metasurface显示文摘Active metasurfaces are emerging as the core of next-generation optical devices with their tunable optical responses and flat-compact topography.Especially for the terahertz band,active metasurfaces have been developed as fascinating devices for optical chopping and compressive sensing imaging.However,performance regulation by changing the dielectric parameters of the integrated functional materials exhibits severe limitations and parasitic losses.Here,we introduce a C-shape-split-ring-based phase discontinuity metasurface with liquid crystal elastomer as the substrate for infrared modulation of terahertz wavefront.Line-focused infrared light is applied to manipulate the deflection of the liquid crystal elastomer substrate,enabling controllable and broadband wavefront steering with a maximum output angle change of 22°at 0.68THz.Heating as another control method is also investigated and compared with infrared control.We further demonstrate the performance of liquid crystal elastomer metasurface as a beam steerer,frequency modulator,and tunable beam splitter,which are highly desired in terahertz wireless communication and imaging systems.The proposed scheme demonstrates the promising prospects of mechanically deformable metasurfaces,thereby paving the path for the development of reconfigurable metasurfaces. | Xiaolin Zhuang Wei Zhang Kemeng Wang Yangfan Gu Youwen An Xueqian Zhang Jianqiang Gu Dan Luo Jiaguang Han Weili Zhang | 2023 | Light(Science & Applications)2023，12，1： | 4 |
| 5 | Polarization-independent all-silicon dielectric metasurfaces in the terahertz regime显示文摘Dielectric metasurfaces have achieved great success in realizing high-efficiency wavefront control in the optical and infrared ranges. Here, we experimentally demonstrate several efficient, polarization-independent, all-silicon dielectric metasurfaces in the terahertz regime. The metasurfaces are composed of cylindrical silicon pillars on a silicon substrate, which can be easily fabricated using etching technology for semiconductors. By locally tailoring the diameter of the pillars, full control over abrupt phase changes can be achieved. To show the controlling ability of the metasurfaces, an anomalous deflector, three Bessel beam generators, and three vortex beam generators are fabricated and characterized. We also show that the proposed metasurfaces can be easily combined to form composite devices with extended functionalities. The proposed controlling method has promising applications in developing low-loss, ultra-compact spatial terahertz modulation devices. | HUIFANG ZHANG XUEQIAN ZHANG QUAN XU QIU WANG YUEHONG XU MINGGUI WEI YANFENG LI JIANQIANG GU ZHEN TIAN CHUNMEI OUYANG XIXIANG ZHANG CONG HU JIAGUANG HAN WEILI ZHANG | 2018 | Photonics Research2018，9，1： | 4 |
| 6 | Impact of clinical research on public health policy of neonatal screening for congenital heart disease in China显示文摘Congenital heart disease(CHD)is one of the most common congenital malformations,with a prevalence of approximately 1%in live births.[1,2]Among them,1/4 to 1/3 are major CHD,including critical CHD(CCHD)and serious CHD,which require surgical or catheter intervention before 1 year of age.[3]Major CHD,if left untreated,may cause serious outcomes,such as heart failure,cardiogenic shock,acidosis,and hypoxic-ischemic brain damage,and is one of the leading causes of infant death and childhood disability.[4]The missed diagnosis rate of CCHD in four nurseries ranges from 13%to 48%in developed countries,[4,5]but in China,is>71%before serious symptoms occur after birth.[6]Therefore,screening for CHD is useful for early detection,diagnosis,and treatment and helps to improve prognosis and reduces the medical,economic,and mental burden to both the family and the society.[5,7] | Miao Yang Youping Tian Pin Jia Xiaojing Ma Xiaoling Ge Xiaojing Hu Quming Zhao Fang Liu Bing Jia Weili Yan Qing Gu Guoying Huang | 2022 | Chinese Medical Journal2022，，11： | 3 |
| 7 | Diketopyrrolopyrrole-Au(I) as singlet oxygen generator for enhanced tumor photodynamic and photothermal therapy显示文摘Diketopyrrolopyrrole(DPP)derivatived photosensitizers(PSs)with near infrared(NIR)absorption and good photophysical properties have drawn tremendous attention in cancer phototherapy.However,current DPP derivatives present unsatisfactory quantum yield of singlet oxygen(1O2)due to the large energy gap between the excited singlet and triplet states.To tackle this challenge,herein the DPP core is functionalized with triphenylphosphine-Au(I)group(Th DPP-Au),leading to a high1O2 quantum yield of 0.65.Theoretical calculation attributes the enhancement to spin-orbit coupling and population of the triplet excition upon photoexcitation.The hydrophilic Th DPP-Au nanoparticals(NPs)are prepared via nano-reprecipitation,which displays homogeneous size and excellent light absorption ability(ε=4.382×104 M-1cm-1).And the Th DPP-Au NPs exhibit low dark toxicity and high phototoxicity,which can effectively kill tumor cells via 1O2 induced mitochondrial apoptotic pathway upon irradiation.Furthermore,in vivo experiments demonstrate that Th DPP-Au NPs can selective accumulation in tumor and present excellent synergistic photodynamic/photothermal therapy guided by fluorescence and photothermal dual imaging. | Xiaoyu Huang Rui Gu Jiewei Li Nan Yang Zijin Chen Weili Si Peng Chen Wei Huang Xiaochen Dong | 2020 | Science China Chemistry2020，63，1： | 3 |
| 8 | Synthetic damage effect assessment through evidential reasoning approach and neural fuzzy inference:Application in ship target显示文摘The damage effect assessment of anti-ship missiles combines system science and weapon science,which can provide reference for the assessment of battlefield damage situation.In order to solve the difficulty of heterogeneous data aggregation and the difficulty in constructing the mapping between factors and damage effect,this paper analyzes the specific damage process of the anti-ship missile to the ship,and proposes a synthetic Evidential Reasoning(ER)–Adaptive Neural Fuzzy Inference System(ANFIS)to assess the damage effect.To solve the problem of fuzziness and uncertainty of criteria in the assessment process,the belief structure model is used to transform qualitative and quantitative information into a unified mathematical structure,and ER algorithm is used to fuse the information of lower-level criteria.In order to solve the problem of fuzziness and uncertainty of the information contained in the first-level variables,and the strong non-linear characteristics of the mapping between first-level variables and damage effect,the ANFIS with selfadaptation and self-learning is constructed.The map between the three first-level variables and damage effect is established,and the interaction process of the various factors in the damage effect assessment are clear.Sensitivity analysis shows that assessment model has good stability.The result analysis and comparative analysis show that the process proposed in this paper can effectively assess the damage effect of anti-ship missiles,and all criteria data are objective and comparable. | Tianle YAO Run MIAO Weili WANG Zhirong LI Jun DONG Yajuan GU Xuefei YAN | 2022 | Chinese Journal of Aeronautics2022，35，8： | 2 |
| 9 | Longitudinal virological changes and underlying pathogenesis in hospitalized COVID-19 patients in Guangzhou,China显示文摘Prolonged viral RNA shedding and recurrence of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)in coronavirus disease 2019(COVID-19)patients have been reported.However,the clinical outcome and pathogenesis remain unclear.In this study,we recruited 43 laboratory-confirmed COVID-19 patients.We found that prolonged viral RNA shedding or recurrence mainly occurred in severe/critical patients(P<0.05).The average viral shedding time in severe/critical patients was more than 50 days,and up to 100 days in some patients,after symptom onset.However,chest computed tomography gradually improved and complete absorption occurred when SARS-CoV-2 RT-PCR was still positive,but specific antibodies appeared.Furthermore,the viral shedding time significantly decreased when the A1,430G or C12,473T mutation occurred(P<0.01 and FDR<0.01)and increased when G227A occurred(P<0.05 and FDR<0.05).High IL1R1,IL1R2,and TNFRSF21 expression in the host positively correlated with viral shedding time(P<0.05 and false discovery rate<0.05).Prolonged viral RNA shedding often occurs but may not increase disease damage.Prolonged viral RNA shedding is associated with viral mutations and host factors. | Zhengtu Li Yinhu Li Ruilin Sun Shaoqiang Li Lingdan Chen Yangqing Zhan Mingzhou Xie Jiasheng Yang Yanqun Wang Airu Zhu Guoping Gu Le Yu Shuaicheng Li Tingting Liu Zhaoming Chen Wenhua Jian Qian Jiang Xiaofen Su Weili Gu Liyan Chen Jing Cheng Jincun Zhao Wenju Lu Jinping Zheng Shiyue Li Nanshan Zhong Feng Ye | 2021 | Science China(Life Sciences)2021，64，12： | 1 |
| 10 | Meta-optics inspired surface plasmon devices显示文摘Surface plasmons(SPs)are electromagnetic surface waves that propagate at the interface between a conductor and a dielectric.Due to their unique ability to concentrate light on two-dimensional platforms and produce very high local-field intensity,SPs have rapidly fueled a variety of fundamental advances and practical applications.In parallel,the development of metamaterials and metasurfaces has rapidly revolutionized the design concepts of traditional optical devices,fostering the exciting field of meta-optics.This review focuses on recent progress of meta-optics inspired SP devices,which are implemented by the careful design of subwavelength structures and the arrangement of their spatial distributions.Devices of general interest,including coupling devices,on-chip tailoring devices,and decoupling devices,as well as nascent SP applications empowered by sophisticated usage of meta-optics,are introduced and discussed. | Quan Xu Yuanhao Lang Xiaohan Jiang Xinyao Yuan Yuehong Xu Jianqiang Gu Zhen Tian Chunmei Ouyang Xueqian Zhang Jiaguang Han Weili Zhang | 2023 | Photonics Insights2023，2，1： | 1 |
| 11 | From high-yield Ti3AlCN ceramics to high-quality Ti3CNTx MXenes through eliminating Al segregation显示文摘Ti3CNTx MXenes with unique electrical conductivity can be widely applied for supercapacitors and electromagnetic shielding.However,its relatively low-yield quaternary nitrogen-containing Ti3AlCN ce ramics precursor(less than 50%),due to the inevitable Al segregation during the synthesizing process,significantly hindered its widely commercial applications.Herein,we employed the controllable AlNoversaturation precursor strategy to precisely tune the phase transition point of quaternary Ti3AlCN ceramics to obtain high-yield Ti3 AlCN precursor for the purpose of high conductivity Ti3 CNTx MXenes.Combined energy dispersive X-ray spectrometer(XRD)with X-ray photoelectron spectroscopy(XPS)characterizations,the yield of the quaternary nitrogen-containing Ti3 AlCN ceramics was evidently proved to be up to 70%,which is 1.4 times than that of previously reported works.Such relatively highyield quaternary Ti3AlCN is mainly ascribed to the elimination of Al segregation.Based on it,we further developed accordion-like two-dimensional(2D)MXene via hydrofluoric acid etch and vacuum freezedry.This novel accordion-like 2D Ti3CNTx MXene possesses high electrochemical capacitive properties(209 F/g).Therefore,this controllable AlN-oversaturation precursor strategy will pave a way to exploit costly high-yield MAX ceramics precursor for high conductivity MXenes and also play a powerful role in promoting their practical applications including electrical and magnetic engineering fields. | Ningjun Chen Haichao Huang Zhong Xu Yanting Xie Da Xiong Xiang Chu Bingni Gu Bo Zheng Weili Deng Haitao Zhang Weiqing Yang | 2020 | Chinese Chemical Letters2020，31，4： | 1 |
| 12 | Terahertz bound states in the continuum with incident angle robustness induced by a dual period metagrating显示文摘Metasurface-empowered bound state in the continuum(BIC)provides a unique route for fascinating functional devices with infinitely high quality factors.This method is particularly attractive to the terahertz community because it may essentially solve the deficiencies in terahertz filters,sensors,lasers,and nonlinear sources.However,most BIC metasurfaces are limited to specified incident angles that seriously dim their application prospects.Here,we propose that a dual-period dielectric metagrating can support multiple families of BICs that originate from guided mode resonances in the dielectric grating and exhibit infinite quality factors at arbitrarily tilted incidence.This robustness was analyzed based on the Bloch theory and verified at tilted incident angles.We also demonstrate that inducing geometric asymmetry is an efficient way to manipulate the leakage and coupling of these BICs,which can mimic the electromagnetically induced transparency(EIT)effect in our dual-period metagrating.In this demonstration,a slow-light effect with a measured group delay of 117 ps was achieved.The incidence-insensitive BICs proposed here may greatly extend the application scenarios of the BIC effect.The high Q factor and outstanding slow-light effect in the metagrating show exciting prospects in realizing high-performance filters,sensors,and modulators for prompting terahertz applications. | Wenqiao Shi Jianqiang Gu Xingyuan Zhang Quan Xu Jiaguang Han Quanlong Yang Longqing Cong Weili Zhang | 2022 | Photonics Research2022，10，3： | 1 |
| 13 | Active-Thermal-Tunable Terahertz Absorber with Temperature-Sensitive Material Thin Film显示文摘It is shown that active-tunable terahertz absorbers can be realized in a sandwich-structured system comprising an ultrathin dielectric film(polyimide) on a temperature-sensitive substrate(InSb) with a metal film on the back by utilizing the intrinsic carrier density(N) variation in InSb. When increasing the temperature from 250 to 320 K, N in InSb varied from ~5.50×1015 to ~2.98×1016 cm–3. Fixing the thickness of dielectric film with the value of 1.37 μm, the absorption peak shifted from 1.41 to 3.29 THz while keeping absorption higher than 99%. This active tunability can respond to even a slight temperature perturbation, and shows polarization insensitivity as well as high tolerance of incidence-angle(absorption peak can still exceed 90% even the incidence angle reaches 60°). Besides, the refractive index of polyimide(PI) has thermal stability at the terahertz range and the merit of good workability. These characteristics guarantee the stability of activetunable performance. The peculiarities and innovations of this proposal promise a wide range of high efficiency terahertz devices, such as thermal sensors, spatial light modulators(SLMs) and so on. | Zhao Zhang Zhen Tian Chao Chang Xueguang Wang Xueqian Zhang Chunmei Ouyang Jianqiang Gu Jiaguang Han Weili Zhang | 2018 | Nanotechnology and Precision Engineering2018，1，2： | 1 |
| 14 | Generating superposed terahertz perfect vortices via a spin-multiplexed all-dielectric metasurface显示文摘Perfect optical vortices(POVs),characterized as a ring radius independent of topological charge(TC),possess extensive application in particle manipulation and optical communication.At present,the complex and bulky optical device for generating POVs has been miniaturized by leveraging the metasurface,and either spindependent or spin-independent POV conversions have been further accomplished.Nevertheless,it is still challenging to generate superposed POVs for incidences with orthogonal circular polarization.Here,a spinmultiplexed all-dielectric metasurface method for generating superposed POVs in the terahertz frequency range is proposed and demonstrated.By using the multiple meta-atom comprised structure as the basic unit,the complex amplitude of two superposed POVs is modulated,decoupled,and subsequently encoded to left-and righthanded circular polarization incidences.Furthermore,two kinds of metasurfaces are fabricated and characterized to validate this controlling method.It is demonstrated that the measured intensity and phase distributions match well with the calculation of the Rayleigh–Sommerfeld diffraction integral,and the radius of superposed POVs is independent of TCs.This work provides promising opportunities for developing ultracompact terahertz functional devices applied to complex structured light generation and terahertz communication,and exploring sophisticated spin angular momentum and orbital angular momentum interactions like the photonic spin-Hall effect. | FAN HUANG QUAN XU WANYING LIU TONG WU JIANQIANG GU JIAGUANG HAN WEILI ZHANG | 2023 | Photonics Research2023，11，3： | 1 |

| 16 | Enhanced efficiency and stability of perovskite solar cells by 2D perovskite vapor-assisted interface optimization显示文摘Organic–inorganic perovskites solar cells(PSCs)have attracted great attention due to their rapid progress in power conversion efficiency(PCE).However,there is still an enormous challenge to achieve both high efficiency and stability devices as the decomposition of perovskite materials under humid and light conditions.Herein,we demonstrate that high efficiency and stability of PSCs can be obtained by the reaction of three-dimensional(3D)perovskite with 1,4-butanediamine iodide(BEAI2)vapor.The incorporation of BEAI2 intensively promotes the crystallization of perovskite film with large grain size(~500 nm).Further characterization reveals that the post-treatment perovskite film delivered low interface trap density with long carrier lifetime(>200 ns),long carrier diffusion length(>600 nm)and large carrier mobility(>1.5 cm^2 V-1S-1).Solar cells employing such post-treatment films demonstrated 19.58%PCE without hysteresis.Moreover,the post-treatment devices can retain over 90%original efficiencies stored under ambient atmospheric conditions and exhibit better stability under 85℃and continuous illumination as a two-dimensional(2D)perovskite thin layer is formed on the surface/or at the grain boundaries of 3D perovskite.This study offers an effective way to obtain PSCs with high efficiency and stability. | Minghui Chen Pengwei Li Chao Liang Hao Gu Weishuang Tong Shiping Cheng Weili Li Ganqing Zhao Guosheng Shao | 2020 | Journal of Energy Chemistry2020，29，6： | 1 |

| 19 | Regulations of Antler Generation and Regeneration by Nutritional Factors显示文摘Antler,one of the secondary sex characteristics of male deer,is a highly valued traditional Chinese medicine. The generation and regeneration of deer antler is regulated not only by hormones,but also by nutritional factors. Nutritional factors have great influences on pedicle generation,first antler generation and antler development. Therefore,this paper summarizes recent advances in the study of the influences of nutritional factors on antler generation and regeneration,analyzes the pathways regulating antler generation and regeneration by nutritional factors,and proposes that nutritional factors regulate antler regeneration by direct pathway and indirect pathway. | Zhao Haiping Sun Weili Wang Zhuo Gu Haijun Wang Yanmei Li Guangyu | 2017 | Animal Husbandry and Feed Science2017，9，3： | 0 |
| 20 | Pepper variome reveals the history and key loci associated with fruit domestication and diversification显示文摘Pepper(Capsicum spp.)is an important vegetable crop that provides a unique pungent sensation when eaten.Through construction of a pepper variome map,we examined the main groups that emerged during domestication and breeding of C.annuum,their relationships and temporal succession,and the molecular events underlying the main transitions.The results showed that the initial differentiation in fruit shape and pungency,increase in fruit weight,and transition from erect to pendent fruits,as well as the recent appearance of large,blocky,sweet fruits(bell peppers),were accompanied by strong selection/fixation of key alleles and introgressions in two large genomic regions.Furthermore,we identified Up,which encodes a BIG GRAIN protein involved in auxin transport,as a key domestication gene that controls erect vs pendent fruit orientation.The up mutation gained increased expression especially in the fruit pedicel through a 579-bp sequence deletion in its 5′upstream region,resulting in the phenotype of pendent fruit.The function of Up was confirmed by virus-induced gene silencing.Taken together,these findings constitute a cornerstone for understanding the domestication and differentiation of a key horticultural crop. | Yacong Cao Kang Zhang Hailong Yu Shumin Chen Donghui Xu Hong Zhao Zhenghai Zhang Yinqing Yang Xiaozhen Gu Xinyan Liu Haiping Wang Yaxin Jing Yajie Mei Xiang Wang Véronique Lefebvre Weili Zhang Yuan Jin Dongliang An Risheng Wang Paul Bosland Xixiang Li IIan Paran Baoxi Zhang Giovanni Giuliano Lihao Wang Feng Cheng | 2022 | Molecular Plant2022，15，11： | 0 |
