| 1 | Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices. | Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng | 2016 | Light(Science & Applications)2016,5,1: | 36 |
| 2 | Tuning Superhydrophobic Materials with Negative Surface Energy Domains显示文摘Hydrophobic/superhydrophobic materials with intrinsic water repellence are highly desirable in engineering fields including antiicing in aerocrafts,antidrag and anticorrosion in ships,and antifog and self-cleaning in optical lenses,screen,mirrors,and windows.However,superhydrophobic material should have small surface energy(SE)and a micro/nanosurface structure which can reduce solid-liquid contact significantly.The low SE is generally found in organic materials with inferior mechanical properties that is undesirable in engineering.Intriguingly,previous theoretical calculations have predicted a negative SE forθ-alumina(θ-Al_(2)O_(3)),which inspires us to use it as a superhydrophobic material.Here,we report the experimental evidence of the small/negative SE ofθ-Al_(2)O_(3) and aθ-Al_(2)O_(3)-based superhydrophobic coating prepared by one-step scalable plasma arcing oxidation.The superhydrophobic coating has complete ceramic and desired micro/nanostructure and therefore exhibits excellent aging resistance,wear resistance,corrosion resistance,high-temperature tolerance,and burning resistance.Owing to the rarity of the small/negative SE in inorganic materials,the concept to reduce SE byθ-Al_(2)O_(3) may foster a blowout to develop robust superhydrophobicity by complete inorganic materials. | Zhongzhen Wu Liangliang Liu Shunning Li Shunping Ji Pinghu Chen Suihan Cui Zhengyong Ma Yuchang Weng Qian Huang Zhongcan Wu Hao Wu Yuan Lin Ricky KYFu Hai Lin Xiubo Tian Paul KChu Feng Pan | 2019 | Research2019,,1: | 6 |
| 3 | Simplified mathematical model of inter-turn short circuit of field windings in hydro-generators and its application显示文摘Inter-turn short circuit of field windings is a common electrical fault of generators.Simulation is an important method of investigating the fault and providing data support for fault monitoring.However,huge numbers of pole pairs and damper loops in large hydro-generators would lead to lengthy calculation time,hindering scientific research and engineering application.To deal with this problem,we analyze a theoretical basis for a damper winding simplified model and then propose an equivalent treatment method.Through the analysis of steady-state current harmonic characteristics of generators with different stator winding configurations during the fault,the simplified models suitable for steady-state calculation are derived from two aspects,namely,additional rotor harmonic current frequency characteristics and the relationship of the amplitude as well as the phase of each branch current of the stator.The calculation and experimental results of the two simplified models are then compared to verify the models' correctness.A calculation example of the Three Gorges left bank VGS generator shows few deviations between the calculation results of the simplified model and the original model.Moreover,the calculation time using the simplified model is 1/1500 that using the original model,which provides a more effective tool for on-line fault monitoring.Finally,the sensitivity-verification application of the fault-monitoring scheme based on the stator steady-state unbalanced current RMS is depicted.The result shows that the scheme can monitor two-turn short circuits of field windings in the Three Gorges generator and provide high sensitivity. | HAO LiangLiang WU JunYong SUN YuGuang WANG XiangHeng | 2013 | Science China(Technological Sciences)2013,56,4: | 5 |
| 4 | Colonization of Bacillus cereus NJSZ-13,a species with nematicidal activity in Masson pine(Pinus massoniana Lamb.)显示文摘Bacillus cereus NJSZ-13,an endophytic bacterium with nematicidal activity,was isolated from stems of healthy Pinus elliottii Engelm.Colonization of P.massoniana Lamb.by endophytic B.cereus was studied using scanning electron microscopy and confocal laser scanning microscopy.After the plasmid p GFP78 containing the green fluorescent protein(GFP)gene was transformed into the NJSZ-13 strain,the NJSZ-13:gfp showed the same nematicidal activity and growth curve as the wild-type strain,and the plasmid p GFP78 was stably maintained in strain NJSZ-13 for at least 96 h of bacterial cultivation on medium without antibiotics.After inoculation into Masson pine roots,colonization of the NJSZ-13:gfp strain in plant roots and stems was visualized using confocal laser scanning and the strain was enumerated in inoculated roots and stems.These results suggest that NJSZ-13:gfp is an efficient colonizer of Masson pine and can transfer vertically from roots to stems. | Liangliang Li Jiajin Tan Fengmao Chen Dejun Hao | 2020 | Journal of Forestry Research2020,31,3: | 4 |
| 5 | Achieving purely organic room temperature phosphorescence in aqueous solution显示文摘Purely organic room temperature phosphorescence(RTP)materials have aroused increasing interests in recent years and have been widely applied in anticounterfeiting,biological imaging,sensing,etc.Currently,these materials can be efficiently developed in crystalline states and amorphous polymer-doped systems.However,achieving organic RTP in solution,especially in water solution,is still a formidable challenge.Recently,reports on aqueous phase RTP have been increasing and some feasible design strategies have been proposed;however,related investigations are still limited and there is a lack of systematic reviews.Therefore,we summarized the recent cases of aqueous phase organic RTP emission with primarily focusing on the RTP properties and efficient design strategies(e.g.,forming nanoparticles from phosphorescent molecules and macrocyclic supramolecular assembly).Moreover,promising applications of the aqueous phase organic RTP emission in bio-imaging and sensing were discussed.Some detailed perspectives concerning materials design and application were provided with the hope to provide inspiration for the future development of aqueous phase organic RTP. | Hao Sun Liangliang Zhu | 2023 | Aggregate2023,4,1: | 2 |

| 7 | The role of Re in improving the oxidation-resistance of a Re modified PtAl coating on Mo-rich single crystal superalloy显示文摘A novel Re modifiedβ-(Ni,Pt)Al coating was prepared on a Mo-rich Ni_3 Al-based single crystal(SC)superalloy by electro-deposition of Re/Pt dual films and low-activity aluminizing.The isothermal oxidation behavior of the Re modifiedβ-(Ni,Pt)Al coating and traditionalβ-(Ni,Pt)Al coating was comparatively studied at 1100℃.Apparent spallation of oxide scale was found on the surface of traditionalβ-(Ni,Pt)Al coating after 300 h isothermal exposure,which mainly resulted from the evaporation of Mo-containing oxides.It is further found that the outward diffusion of Mo from the SC substrate was effectively inhibited in the Re modifiedβ-(Ni,Pt)Al coating by forming theσ-MoRe phase both at the coating/superalloy interface and grain boundaries.It is also revealed that the addition of Re can stabilise Mo to form theσ-MoRe phase,allowing the improved oxidation resistance of the Re modifiedβ-(Ni,Pt)Al coating. | Jingchen Li Liangliang Wei Jian He Hao Chen Hongbo Guo | 2020 | Journal of Materials Science & Technology2020,58,23: | 1 |

| 10 | Corrosion fatigue behavior of friction stir processed interstitial free steel显示文摘In this study, interstitial free(IF) steel plates were subjected to double-sided friction stir processing(FSP).The fine-grained structure with an average grain size of about 12 m was obtained in the processed zone(PZ) with a thickness of about 2.5 mm. The yield strength(325 MPa) and ultimate tensile strength(451 MPa) of FSP IF steel were significantly higher than those of base material(BM)(192 and 314 MPa),while the elongation(67.5%) almost remained unchanged compared with the BM(66.2%). The average microhardness value of the PZ was about 130 HV, 1.3 times higher than that of the BM. In addition, the FSP IF steel showed a more positive corrosion potential and lower corrosion current density than the BM,exhibiting lower corrosion tendency and corrosion rates in a 3.5 wt% NaCl solution. Furthermore, FSP IF steel exhibited higher fatigue life than the BM both in air and NaCl solution. Corrosion fatigue fracture surfaces of FSP IF steel mainly exhibited a typical transgranular fracture with fatigue striations, while the BM predominantly presented an intergranular fracture. Enhanced corrosion fatigue performance was mainly attributed to the increased resistance of nucleation and growth of fatigue cracks. The corrosion fatigue mechanism was primarily controlled by anodic dissolution under the combined effect of cyclic stress and corrosive solution. | Wen Wang Ruiqi Xu Yaxin Hao Qiang Wang Liangliang Yu Qianying Che Jun Cai Kuaishe Wang Zongyi Ma | 2018 | Journal of Materials Science & Technology2018,34,1: | 1 |

| 12 | Routing emission with a multi-channel nonreciprocal waveguide显示文摘In this work, we present a multi-channel nonreciprocal waveguide, which is composed of a gyrotropic-bounded dielectric on the bottom and a plasmonic material on the top. The Lorentz reciprocity in the time-invariant system is broken when applying an external static magnetic field on the gyrotropic material. The nonreciprocal emission from the dipole source located in the center of the waveguide is observed in extended waveband channels. The proposed heterostructure serves as a photonic dichroism once the dielectric is replaced by a nonlinear material.The associated second harmonic generated in the nonlinear process can be separated from the fundamental signal under proper magnetic field intensity. Our findings may provide significant guidance for designing nonreciprocal photonic devices with superiorities of a tunable waveband, multiple channels, and small footprint. | HAO HU LIANGLIANG LIU XIAO HU DONGJUE LIU DONGLIANG GAO | 2019 | Photonics Research2019,7,6: | 1 |
| 13 | High-performance photodetector based on an interface engineering-assisted graphene/silicon Schottky junction显示文摘Graphene/silicon Schottky junctions have been proven efficient for photodetection,but the existing high dark current seriously restricts applications such as weak signal detection.In this paper,a thin layer of gadolinium iron garnet(Gd3Fe5O12,GdIG)film is introduced to engineer the interface of a graphene/silicon Schottky photodetector.The novel structure shows a significant decrease in dark current by 54 times at a-2 V bias.It also exhibits high performance in a self-powered mode in terms of an Ilight/Idark ratio up to 8.2×10^(6)and a specific detectivity of 1.35×10^(13)Jones at 633 nm,showing appealing potential for weak-light detection.Practical suitability characterizations reveal a broadband absorption covering ultraviolet to near-infrared light and a large linear response with a wide range of light intensities.The device holds an operation speed of 0.15 ms,a stable response for 500 continuous working cycles,and long-term environmental stability after several months.Theoretical analysis shows that the interlayer increases the barrier height and passivates the contact surface so that the dark current is suppressed.This work demonstrates the good capacity of GdIG thin films as interlayer materials and provides a new solution for high-performance photodetectors. | Peirui Ji Shuming Yang Yu Wang Kaili Li Yiming Wang Hao Suo Yonas Tesfaye Woldu Xiaomin Wang Fei Wang Liangliang Zhang Zhuangde Jiang | 2022 | Microsystems & Nanoengineering2022,8,1: | 1 |
| 14 | Discovery of potential anti-SARS-CoV-2 drugs based on large-scale screening in vitro and effect evaluation in vivo显示文摘The coronavirus disease 2019(COVID-19)pandemic caused by severe acute respiratory syndrome coronavirus 2(SARSCoV-2)is a global crisis.Clinical candidates with high efficacy,ready availability,and that do not develop resistance are in urgent need.Despite that screening to repurpose clinically approved drugs has provided a variety of hits shown to be effective against SARS-CoV-2 infection in cell culture,there are few confirmed antiviral candidates in vivo.In this study,94 compounds showing high antiviral activity against SARS-CoV-2 in Vero E6 cells were identified from 2,580 FDA-approved small-molecule drugs.Among them,24 compounds with low cytotoxicity were selected,and of these,17 compounds also effectively suppressed SARS-CoV-2 infection in He La cells transduced with human ACE2.Six compounds disturb multiple processes of the SARSCoV-2 life cycle.Their prophylactic efficacies were determined in vivo using Syrian hamsters challenged with SARS-CoV-2infection.Seven compounds reduced weight loss and promoted weight regain of hamsters infected not only with the original strain but also the D614G variant.Except for cisatracurium,six compounds reduced hamster pulmonary viral load,and IL-6 and TNF-αm RNAwhen assayed at 4 d postinfection.In particular,sertraline,salinomycin,and gilteritinib showed similar protective effects as remdesivir in vivo and did not induce antiviral drug resistance after 10 serial passages of SARS-CoV-2 in vitro,suggesting promising application for COVID-19 treatment. | Haoran Peng Cuiling Ding Liangliang Jiang Wanda Tang Yan Liu Lanjuan Zhao Zhigang Yi Hao Ren Chong Li Yanhua He Xu Zheng Hailin Tang Zhihui Chen Zhongtian Qi Ping Zhao | 2022 | Science China(Life Sciences)2022,65,6: | 1 |
| 15 | κ-Opioid receptor activation attenuates osteoarthritis synovitis by regulating macrophage polarization through the NF-κB pathway显示文摘Osteoarthritis(OA)is a prevalent and chronic joint disease that affects the aging population,causing pain and disability.Macrophages in synovium are important mediators of synovial inflammatory activity and pathological joint pain.Previous studies have demonstrated the significant involvement of k-opioid receptor(KOR)in the reg-ulation of pain and inflammation.Our study reveals a significant reduction in synovial KOR expression among patients and mice with OA.Here,we find that KOR activation effectively inhibits the expressions of the LPS-induced-inflammatory cytokines TNF-αand IL-6 by inhibiting macrophage M1 phenotype.Mechanistically,KOR activation effectively suppresses the proinflammatory factor secretion of macrophages by inhibiting the translocation of NF-kB into the nucleus.Our animal experiments reveal that activation of KOR effectively alleviates knee pain and prevents synovitis progression in OA mice.Consistently,KOR administration suppresses the expressions of M1 macrophage markers and the NF-kB pathway in the synovium of the knee.Collectively,our study suggests that targeting KOR may be a viable strategy for treating OA by inhibiting synovitis and improving joint pain in affected patients. | Yi Shi Huaqiang Tao Xueyan Li Liyuan Zhang Chunhui Li Wen Sun Miao Chu Kai Chen Pengfei Zhu Qiang Wang Chengyong Gu Liangliang Wang Xing Yang Yuefeng Hao | 2024 | Acta Biochimica et Biophysica Sinica2024,56,1: | 0 |
| 16 | Physiological and molecular bases of the boron deficiency response in tomatoes显示文摘Boron is an essential microelement for plant growth.Tomato is one of the most cultivated fruits and vegetables in the world,and boron deficiency severely inhibits its yield and quality.However,the mechanism of tomato in response to boron deficiency remains largely unclear.Here,we investigated the physiological and molecular bases of the boron deficiency response in hydroponically grown tomato seedlings.Boron deficiency repressed the expression of genes associated with nitrogen metabolism,while it induced the expression of genes related to the pentose phosphate pathway,thereby altering carbon flow to provide energy for plants to cope with stress.Boron deficiency increased the accumulation of copper,manganese and iron,thereby maintaining chlorophyll content and photosynthetic efficiency at the early stage of stress.In addition,boron deficiency downregulated the expression of genes involved in cell wall organization and reduced the contents of pectin and cellulose in roots,ultimately retarding root growth.Furthermore,boron deficiency markedly altered phytohormone levels and signaling pathways in roots.The contents of jasmonic acid,jasmonoy1-L-isoleucine,trans-zeatin riboside,abscisic acid,salicylic acid,and SA glucoside were decreased;in contrast,the contents of isopentenyladenine riboside and ethylene precursor 1-aminocyclopropane-1-carboxylic acid were increased in the roots of boron-deficient tomato plants.These results collectively indicate that tomato roots reprogram carbon/nitrogen metabolism,alter cell wall components and modulate phytohormone pathways to survive boron deficiency.This study provides a theoretical basis for further elucidating the adaptive mechanism of tomato in response to boron deficiency. | Junjun Li Huihui Fan Qianqian Song Lili Jing Hao Yu Ruishan Li Ping Zhang Fei Liu Weimin Li Liangliang Sun Jin Xu | 2023 | Horticulture Research2023,10,12: | 0 |
| 17 | The effect of hydrogen on the recombination of Frenkel pair in tungsten: A theoretical insight显示文摘Tungsten (W), with its primary advantages, is considered as the most promising candidate for plasma facing materials (PFMs) for the next generation of fusion devices such as ITER. However, continuous bombardment with 14.1 MeV neutron introduces Frenkel defects as the primary damage in W [1]. The Frenkel defects, composed of self-interstitial atoms (SIAs) and vacancies, can develop to extended defects such as voids and interstitial clusters, resulting in hardening, swelling and embrittlement of W, thus degrading the properties of W [2]. The recombination of SIAs and vacancies is an effective way to reduce the Frenkel defects in bulk W, which enhances the radiation resistance of W based on recent theoretical calculations [3,4]. The moving of the SIA to the vacancy could finish the recombination process through instantaneous or thermally activated way [3]. The instantaneous recombination region is an ellipse with the semi-minor axis of 5.4 ? and semi-major axis of 18 ? according to the molecular dynamics calculation [4]. | ShiYao Qin Shuo Jin LiangLiang Niu JianNan Hao HongBo Zhou GuangHong Lu | 2017 | Science China(Physics,Mechanics & Astronomy)2017,60,6: | 0 |

| 19 | Origin of superior pseudocapacitive mechanism of transition metal nitrides显示文摘Large-scale deployment of Internet of Things (IoT),a revolutionary innovation for a better world,is hampered by the limitation of energy self-sufficiency.Constructing transition metal nitride (TMN)-based micro-supercapacitors is a possible solution by taking advantage of the high conductivity,large specific capacitance,and large tap density of the materials.However,the pseudocapacitive storage mechanism of TMNs is still unclear consequently impeding the design of microdevices.Herein,the functions and mechanism of TMNs with different metal oxynitride (TMNO_(x)) concentrations in pseudocapacitive electrodes are investigated systematically by in situ Raman scattering,ex situ X-ray photoelectron spectroscopy,as well as ion isolation and substitution cyclic voltammetry.It is found that the specific capacitances of TMNs depend on the TMNO_(x) concentrations and the N–M–O site is responsible for the large pseudocapacitance via the Faradic reaction between TMNO_(x) and OH^(-).Our study elucidates the mechanism pertaining to pseudocapacitive charge storage of TMNs and provides insights into the design and optimization of TMNO_(x) as well as other electrode materials for pseudocapacitors. | Chao Huang Ping Qin Dan Li Qingdong Ruan Hao Song Liangliang Liu Yuzheng Wu Yinghe Ma Qingwei Li Kaifu Huo Paul K.Chu | 2022 | Journal of Energy Chemistry2022,31,6: | 0 |
| 20 | CuS Electrode for All-pH Electrolyte in Aqueous Batteries显示文摘With their excellent safety, affordability, environmental friendliness and high ionic conductivity, aqueous batteries are prospective contenders to replace lithium-ion batteries. However, the pH of aqueous electrolyte might impact the battery’s electrochemical performance and even its normal operation. It is critical to develop an electrode that can work in different pH settings. The hydrothermal method and vulcanization treatment were used to successfully create copper sulfide(CuS) nanosheet in this work. It can store and transport nonmetal and metal ions as well as polyvalent ions with a high charge radius ratio, and function normally under a variety of pH conditions. The CuS electrode has a considerable capacity(900 mA·h/g) and rate performance under alkaline conditions, as well as an ultra-long discharge platform, which contribute to 80% of the total capacity. | Liangliang Yang Mangwei Cui Qingjiang Liu Hao Lei Yan Huang | 2022 | Journal of Harbin Institute of Technology(New Series)2022,29,6: | 0 |
