| 1 | Vectorial optical fields: recent advances and future prospects显示文摘Driven by their potential applications, vectorial optical fields with spatially inhomogeneous states of polarization within the cross section have drawn significant attention recently. This work intends to review some of the latest development of this rapidly growing field of optics and offer a general overview of the current status of this field in a few areas. Mathematical descriptions of generalized vectorial optical fields are provided along with several special examples. A time-reversal methodology for the creation of a wide variety of exotic optical focal fields with prescribed characteristics within the focal volume is presented. Recently developed methods for the generation of vectorial optical fields that utilize fiber lasers,digital lasers, vectorial optical field generator, metasurfaces or photoalignment liquid crystals are summarized. The interactions of these vectorial optical fields with various micro-and nano-structures are presented and the prospects of their potential applications are discussed. The connection of vectorial optical fields with higher dimensionality in quantum information is summarized. | Jian Chen Chenhao Wan Qiwen Zhan | 2018 | Science Bulletin2018，63，1： | 15 |
| 2 | Effective removal of microcystins using carbon nanotubes embedded with bacteria显示文摘Adsorption of microcystins (MCs) by carbon nanotubes (CNTs) and clay materials was studied. Compared with various clays tested, CNTs showed a much stronger ability to adsorb MC-RR and LR that were two typical types of microcystins found in China. At initial 21.0 mg/L of MC-RR and 9.5 mg/L of MC-LR in solution, the adsorption amounts of MC-RR and LR by CNTs were 14.8 and 6.7 mg/g that were about five times higher than those by the clay ma-terials of sepiolite, kaolinite and talc, etc. In the presence of CNTs and the bacterial Ralstonia solanacearum that was firstly isolated and used for the biodegradation of MCs by the authors, a remarkable removal of MCs from water were observed. The mechanism was that CNTs could absorb large amount of both MCs and the embedded R. solanacearum so that, even when diluted by a large amount of water, the con-centrations of both organic pollutants and the added bacteria could be largely enhanced on the surface of CNTs where a concerted biodegradation reaction was effectively conducted. This finding could be important for the further development of practical techniques to eliminate MCs from polluted drinking waters. | YANHai PANGang ZOUHua LiXianliang CHENHao | 2004 | Chinese Science Bulletin2004，49，16： | 12 |
| 3 | Engineering photonic angular momentum with structured light:a review显示文摘Structured light with inhomogeneous phase,amplitude,and polarization spatial distributions that represent an infinite-dimensional space of eigenstates for light as the ideal carrier can provide a structured combination of photonic spin and orbital angular momentum(OAM).Photonic spin angular momentum(SAM)interactions with matter have long been studied,whereas the photonic OAM has only recently been discovered,receiving attention in the past three decades.Although controlling polarization(i.e.,SAM)alone can provide useful information about the media with which the light interacts,light fields carrying both OAM and SAM may provide additional information,permitting new sensing mechanisms and light–matter interactions.We summarize recent developments in controlling photonic angular momentum(AM)using complex structured optical fields.Arbitrarily oriented photonic SAM and OAM states may be generated through careful engineering of the spatial and temporal structures of optical fields.Moreover,we discuss potential applications of specifically engineered photonic AM states in optical tweezers,directional coupling,and optical information transmission and processing. | Jian Chen Chenhao Wan Qiwen Zhan | 2021 | Advanced Photonics2021，3，6： | 11 |
| 4 | Review and discussion on fire behavior of bridge girders显示文摘This paper presents an overview on fire behavior of bridge girders mainly including prestressed concrete(PC) bridge girders and steel bridge girders. The typical fire accidents occurred on bridges are illustrated and, the seriousness of posing threats to bridge structures resulted from increasing traffic fires, specially intense hydrocarbon fires generated from petrol-chemicals, is highlighted. The current researches, embracing high-temperature properties of constituent materials, prestress state, measurement in fire tests, numerical methods, structural fire resistance, and so forth, taken on coping with problems existing in fire behavior and structural fire behavior in bridge girders are reviewed and discussed. Further, strategies for enhancing fire resistance of bridge girders followed with failure criterion and mode in types of bridge structures are provided. Future research area along with emerging trends in structural fire behavior of bridge girders is also recommended for mitigating fire hazards occurred on bridge girders. Herein, it can be attained a conclusion from review and discussion that prestressed concrete bridge girders with thin webs, specially T-shaped bridge girder, are prone to unstable under fire exposure conditions. High-strength concrete utilized in prestressed concrete bridge girders is vulnerable to spalling at elevated temperature. Steel-truss bridge girder present a more significant fragility to fire exposure compared than other steel bridge girders. | Gang Zhang Xiaocui Zhao Zelei Lu Chaojie Song Xuyang Li Chenhao Tang | 2022 | Journal of Traffic and Transportation Engineering(English Edition)2022，9，3： | 11 |
| 5 | PLL DEMODULATION TECHNIQUE FOR M-RAY POSITION PHASE SHIFT KEYING显示文摘The paper presents a kind of transmission system which employs M-ary Position Phase Shift Keying(MPPSK) to send data and Phase Locked Loop(PLL) based techniques for data retrieve.With a single PLL, MPPSK demodulation is achieved, as well as carrier recovery and symbol synchronization.Firstly, MPPSK modulation method is briefly introduced.2PPSK's PSD expression is given with its optimization result.Orthogonal Phase Detector(PD) and static threshold are used for the purpose of wider phase range and simplicity in demodulation.The data rate is alterable, which is 4.65 kbps for 2PPSK and 9.3 kbps for 4PPSK in the paper.Then some indicative comparisons in Signal to Noise Ratio Symbol Error Rate(SNR-SER) are made among 2PPSK, 3PPSK and 4PPSK, of which 4PPSK has proved to be optimal in ten slots each symbol conditions.And finally, it is demonstrated by system simulations that lower than 10-4 Symbol Error Rate(SER) performance can be obtained at 13 dB symbol SNR. | Qi Chenhao Wu Lenan | 2009 | Journal of Electronics(China)2009，26，3： | 10 |
| 6 | CN-DBpedia2: An Extraction and Verification Framework for Enriching Chinese Encyclopedia Knowledge Base显示文摘Knowledge base plays an important role in machine understanding and has been widely used in various applications, such as search engine, recommendation system and question answering. However, most knowledge bases are incomplete, which can cause many downstream applications to perform poorly because they cannot find the corresponding facts in the knowledge bases. In this paper, we propose an extraction and verification framework to enrich the knowledge bases. Specifically, based on the existing knowledge base, we first extract new facts from the description texts of entities. But not all newly-formed facts can be added directly to the knowledge base because the errors might be involved by the extraction. Then we propose a novel crowd-sourcing based verification step to verify the candidate facts. Finally, we apply this framework to the existing knowledge base CN-DBpedia and construct a new version of knowledge base CN-DBpedia2, which additionally contains the high confidence facts extracted from the description texts of entities. | Bo Xu Jiaqing Liang Chenhao Xie Bin Liang Lihan Chen Yanghua Xiao | 2019 | Data Intelligence2019，1，3： | 9 |
| 7 | Preparation and evaluation of α-Al2O3 supported lithium ion sieve membranes for Li^+ extraction显示文摘Spinel lithium manganese oxide ion-sieves have been considered the most promising adsorbents to extract Li^+ from brines and sea water.Here,we report a lithium ion-sieve which was successfully loaded onto tubular α-Al2 O3 ceramic substrates by dipping crystallization and post-calcination method.The lithium manganese oxide Li4 Mn5 O(12)was first synthesized onto tubular α-Al2 O3 ceramic substrates as the ion-sieve precursor(i.e.L-AA),and the corresponding lithium ion-sieve(i.e.H-AA) was obtained after acid pickling.The chemical and morphological properties of the ion-sieve were confirmed by X-ray diffraction(XRD) and scanning electron microscopy(SEM).Both L-AA and H-AA showed characteristic peaks of α-Al2 O3 and cubic phase Li4 Mn5 O(12) and the peaks representing cubic phase could still exist after pickling.The lithium manganese oxide Li4 Mn5 O(12) could be uniformly loaded not only on the surface of α-Al2 O3 ubstrates but also inside the pores.Moreover,we found that the equilibrium adsorption capacity of H-AA was 22.9 mg·g^-1.After 12 h adsorption,the adsorption balance was reached.After 5 cycles of adsorption,the adsorption capacity of H-AA was 60.88% of the initial adsorption capacity.The process of H-AA adsorption for Li^+correlated with pseudo-second order kinetic model and Langmuir model.Adsorption thermodynamic parameters regarding enthalpy(△N), Gibbs free energy(△G) and entropy(AS) were calculated.For the dynamic adsorptiondesorption process of H-AA,the H-AA exhibited excellent adsorption performance to Li^+ with the Li^+ dynamic adsorption capacity of 9.74 mg·g^-1 and the Mn^2+dissolution loss rate of 0.99%.After 3 dynamic adsorption-desorption cycles,80% of the initial dynamic adsorption capacity was still kept. | Feng Xue Xiaoxian Zhang Yue Niu Chenhao Yi Shengui Ju Weihong Xing | 2020 | Chinese Journal of Chemical Engineering2020，28，9： | 6 |
| 8 | Flexible control strategy for HVDC transmission system adapted to intermittent new energy delivery显示文摘Intermittent new energy delivery requires increasing the flexibility of ultra-high voltage direct current(DC)power adjustment.Based on a converter steady-state model and a DC power model,the control angle constraints of a converter valve are relaxed for power regulation.In this paper,a flexible DC power control method based on a fixed tap changer position is proposed.The initial ratio of the converter transformer is optimized.The effects of the fixed-tap changer position control on the control angle,reactive power compensation,and commutation failure are analyzed.The new control method allows a DC system to operate at a large angle and increase the additional reactive power loss while improving the commutation security margin.Steady-state and electromagnetic transient simulations in the CIGRE test system verify the validity of the method proposed in this paper and the correctness of the analysis conclusions. | Chenhao Li Kuan Li Changhui Ma Pengfei Zhang Qi Tao Yingtao Sun Xin Wang | 2021 | Global Energy Interconnection2021，4，4： | 6 |
| 9 | Spatiotemporal variation in snow cover and its effects on grassland phenology on the Mongolian Plateau显示文摘Snow cover is an important water source for vegetation growth in arid and semi-arid areas,and grassland phenology provides valuable information on the response of terrestrial ecosystems to climate change.The Mongolian Plateau features both abundant snow cover resources and typical grassland ecosystems.In recent years,with the intensification of global climate change,the snow cover on the Mongolian Plateau has changed correspondingly,with resulting effects on vegetation growth.In this study,using MOD10A1 snow cover data and MOD13A1 Normalized Difference Vegetation Index(NDVI)data combined with remote sensing(RS)and geographic information system(GIS)techniques,we analyzed the spatiotemporal changes in snow cover and grassland phenology on the Mongolian Plateau from 2001 to 2018.The correlation analysis and grey relation analysis were used to determine the influence of snow cover parameters(snow cover fraction(SCF),snow cover duration(SCD),snow cover onset date(SCOD),and snow cover end date(SCED))on different types of grassland vegetation.The results showed wide snow cover areas,an early start time,a late end time,and a long duration of snow cover over the northern Mongolian Plateau.Additionally,a late start,an early end,and a short duration were observed for grassland phenology,but the southern area showed the opposite trend.The SCF decreased at an annual rate of 0.33%.The SCD was shortened at an annual rate of 0.57 d.The SCOD and SCED in more than half of the study area advanced at annual rates of 5.33 and 5.74 DOY(day of year),respectively.For grassland phenology,the start of the growing season(SOS)advanced at an annual rate of 0.03 DOY,the end of the growing season(EOS)was delayed at an annual rate of 0.14 DOY,and the length of the growing season(LOS)was prolonged at an annual rate of 0.17 d.The SCF,SCD,and SCED in the snow season were significantly positively correlated with the SOS and negatively correlated with the EOS and LOS.The SCOD was significantly negatively correlated with the SOS and positively correlated with the EOS and LOS.The SCD and SCF can directly affect the SOS of grassland vegetation,while the EOS and LOS were obviously influenced by the SCOD and SCED.This study provides a scientific basis for exploring the response trends of alpine vegetation to global climate change. | SA Chula MENG Fanhao LUO Min LI Chenhao WANG Mulan ADIYA Saruulzaya BAO Yuhai | 2021 | Journal of Arid Land2021，13，4： | 5 |
| 10 | Spatial distribution analysis of landslides triggered by the 2013-04-20 Lushan earthquake,China显示文摘The 2013-04-20 Lushan earthquake(seismic magnitude Ms 7.0 according to the State Seismological Bureau)induced a large number of landslides.In this study,spatial characteristics of landslides are developed by interpreting digital aerial photography data.Seven towns near the epicenter,with an area of about 11.11 km2,were severely affected by the earthquake,and 703 landslides were identified from April 24,2013 aerial photography data over an area of 1.185 km2.About 55.56% of the landslide area was less than 1000 m2,whereas about 3.23 % was more than 10,000 m2.Rock falls and shallow landslides were the most commonly observed types in the study area,and were primarily located in the center of Lushan County.Most landslide areas were widely distributed near river channels and along roads.Five main factors were chosen to study the distribution characteristics of landslides:elevation,slope gradients,fault,geologic unit and river system.The spatial distribution of coseismal landslides is studied statistically using both landslide point density(LPD),defined as the number of landslides(LS Number)per square kilometer,and landslide area density(LAD),interpreted as the percentage of landslides area affected by earthquake.The results show that both LPD and LAD have strong positive correlations with five main factors.Most landslides occurred in the gradient range of 40°-50° and an elevation range of 1.0-1.5 km above sea level.Statistical results also indicate that landslides were mainly formed in soft rocks such as mudstone and sandstone,and concentrated in IX intensity areas. | Chang Ming Tang Chuan Xia Chenhao Fang Qunsheng | 2016 | Earthquake Engineering and Engineering Vibration2016，15，1： | 4 |
| 11 | The influence of ^(18)F-fluorodeoxyglucose positron emission tomography/computed tomography on the N-and M-staging and subsequent clinical management of intrahepatic cholangiocarcinoma显示文摘Background:Intrahepatic cholangiocarcinoma(ICC)is a highly metastatic cancer.^(18)F-fluorodeoxyglucose positron emission tomography/computed tomography(^(18)F-FDG PET/CT)enables sensitive tumor and metastasis detection.Our aim is to evaluate the influence of pre-treatment PET/CT on the N-and M-staging and subsequent clinical management in ICC patients.Methods:Between August 2010 and August 2018,660 consecutive ICC patients,without prior anti-tumor treatments nor other malignancies,were enrolled.The diagnostic performance of PET/CT on the N-and M-staging was compared with conventional imaging,and the preoperative staging accuracy and treatment re-allocation by PET/CT were retrospectively calculated.Survival difference was compared between patients receiving PET/CT or not after propensity score matching.Results:Patients were divided into group A(n=291)and group B(n=369)according to whether PET/CT was performed.Among 291 patients with both PET/CT and conventional imaging for staging in group A,PET/CT showed significantly higher sensitivity(83.0%vs.70.5%,P=0.001),specificity(88.3%vs.74.9%,P<0.001)and accuracy(86.3%vs.73.2%,P<0.001)than conventional imaging in diagnosing regional lymph node metastasis,as well as higher sensitivity(87.8%vs.67.6%,P<0.001)and accuracy(93.5%vs.89.3%,P=0.023)in diagnosing distant metastasis.Overall,PET/CT improved the accuracy of preoperative staging from 60.1%to 71.8%(P<0.001),and modified clinical treatment strategy in 5.8%(17/291)of ICC patients,with unique roles in different tumor-node-metastasis(TNM)stages.High tumor-to-non-tumor ratio(TNR)predicted poor overall survival[hazard ratio(HR)=2.17;95%confidence interval(CI):1.49-3.15;P<0.001].Furthermore,patients performing PET/CT had longer overall survival compared with those without PET/CT(HR=0.74;95%CI:0.58-0.93;P=0.011)after propensity score matching.Conclusions:PET/CT was valuable for diagnosing regional lymph node metastasis and distant metastasis in ICC patients,and facilitated accurate tumor staging and optimal treatment allocation. | Youpei Lin Huanhuan Chong Guohe Song Chenhao Zhang Liangqing Dong Ling Aye Fei Liang Shuaixi Yang Mengsu Zeng Guangyu Ding Shu Zhang Jieyi Shi Aiwu Ke Xiaoying Wang Jian Zhou Jia Fan Qiang Gao | 2022 | Hepatobiliary Surgery and Nutrition2022，11，5： | 3 |
| 12 | Linear polarization holography显示文摘Polarization holography is a newly researched field,that has gained traction with the development of tensor theory.It primarily focuses on the interaction between polarization waves and photosensitive materials.The extraordinary capabil-ities in modulating the amplitude,phase,and polarization of light have resulted in several new applications,such as holo-graphic storage technology,multichannel polarization multiplexing,vector beams,and optical functional devices.In this paper,fundamental research on polarization holography with linear polarized wave,a component of the theory of polariz-ation holography,has been reviewed.Primarily,the effect of various polarization changes on the linear and nonlinear po-larization characteristics of reconstructed wave under continuous exposure and during holographic recording and recon-struction have been focused upon.The polarization modulation realized using these polarization characteristics exhibits unusual functionalities,rendering polarization holography as an attractive research topic in many fields of applications.This paper aims to provide readers with new insights and broaden the application of polarization holography in more sci-entific and technological research fields. | Jinyu Wang Xiaodi Tan Peiliang Qi Chenhao Wu Lu Huang Xianmiao Xu Zhiyun Huang Lili Zhu Yuanying Zhang Xiao Lin Jinliang Zang Kazuo Kuroda | 2022 | Opto-Electronic Science2022，1，2： | 3 |

| 14 | A method to extract algae toxin of microcystin-LR显示文摘A simple and low-cost method to obtain cyanobacterial toxin microcystin-LR(MC-LR) was developed. A new strain of Microcystis aeruginosa, named DC-1, producing microcystin-LR but not microcystin-RR, was separated from the field blooming algae samples of Dianchi Lake, in southwest of China. Following three times’ freeze and thaw treatment, the cultivated DC-1 cells were extracted with 40% methanol in water. The extract was centrifuged and the supernatant applied to a Hydrophilic-Lipophilic Balance(HLB) SPE cartridge. Eluted impurities with a certain gradient from 30% to 50% methanol in water, MC-LR was finally eluted from the HLB cartridge with 60% methanol in water, and samples containing 3.85% to 14.8% of MC-LR were obtained. These MC-LR samples may be used in adsorption and biodegradation experiments instead of using expensive standard reagents. | ZHANGMing-ming PANGang YANHai CHENHao | 2004 | Journal of Environmental Sciences2004，16，4： | 3 |
| 15 | Photonic orbital angular momentum with controllable orientation显示文摘Vortices are whirling disturbances,commonly found in nature,ranging from tremendously small scales in Bose-Einstein condensations to cosmologically colossal scales in spiral galaxies.An optical vortex,generally associated with a spiral phase,can carry orbital angular momentum(OAM).The optical OAM can either be in the longitudinal direction if the spiral phase twists in the spatial domain or in the transverse direction if the phase rotates in the spatiotemporal domain.In this article,we demonstrate the intersection of spatiotemporal vortices and spatial vortices in a wave packet.As a result of this intersection,the wave packet hosts a tilted OAM that provides an additional degree of freedom to the applications that harness the OAM of photons. | Chenhao Wan Jian Chen Andy Chong Qiwen Zhan | 2022 | National Science Review2022，9，7： | 2 |
| 16 | Al2O3 supported hybrid Pd-CeO2 colloidal spheres and its enhanced catalytic performances for methane combustion显示文摘Fabrication of novel nano-catalyst with improved activity and stability has been a hot topic in heterogeneous catalysis. Herein a novel approach was designed to synthesize Pd-CeO2 colloidal assembled spheres(CASs) in one-pot fashion. The Pd clusters were encompassed by the CeO2 nanocrystals with a high dispersity. Based on this hybrid structure, the Pd/ceria interface area can be greatly improved. After Pd-CeO2 CASs was supported on γ-Al2O3, its catalytic activity for CH4 combustion was evaluated. The result shows that Al2O3 supported Pd-CeO2 CASs exhibits an improved catalytic activity and stability,compared to the Pd/CeO2 catalyst prepared by impregnation method. The results of several characterization techniques indicate that the enhanced catalytic activity of Al2O3 supported Pd-CeO2 CASs can be attributed to the more interfacial Pd-O-Ce species and the more surface active oxygen species. | Xinwei Yang Chenhao Du Yanglong Guo Yun Guo Li Wang Yunsong Wang Wangcheng Zhan | 2019 | Journal of Rare Earths2019，37，7： | 2 |
| 17 | Sculpturing spatiotemporal wavepackets with chirped pulses显示文摘Pulse shaping has become a powerful tool in generating complicated ultrafast optical waveforms to meet specific application needs.Traditionally,pulse shaping focuses on the temporal waveform synthesis.Recent interests in structuring light in the spatiotemporal domain rely on Fourier analysis.A space-to-time mapping technique allows us to directly imprint complex spatiotemporal modulation through taking advantage of the relationship between frequency and time of chirped pulses.The concept is experimentally verified through the generation of spatiotemporal optical vortex(STOV)and STOV lattice.The power of this method is further demonstrated by STOV polarity reversal,vortex collision,and vortex annihilation.Such a direct mapping technique opens tremendous potential opportunities for sculpturing complex spatiotemporal waveforms. | QIAN CAO JIAN CHEN KEYIN LU CHENHAO WAN ANDY CHONG QIWEN ZHAN | 2021 | Photonics Research2021，9，11： | 2 |
| 18 | Binding and Transformation of Extracellular DNA in Soil显示文摘DNA is the genetic material of various organisms. Extracellular DNA adsorbed or bound on surface-active particles in soils has been shown to persist for long periods against nucleases degradation and still retain the ability to transform competent cells. This paper reviews some recent advances on the binding and transformation of extracellular DNA in soils,which is fundamental to understanding the nature of the soil, regulating biodiversity, and assessing the risk of releasing genetically engineered microorganisms (GEMs) as well as being helpful for development of the genetic evolutional theory of bacteria. Several influencing factors, such as soil pH, ionic strength, soil surface properties, and characteristics of the DNA polymer, are discussed. To date, the understanding of the type of molecular binding sites and the conformation of adsorbed and bound DNA to soil particles is still in its infancy. | CAIPeng HUANGQiao-Yun ZHANGXue-Wen CHENHao | 2005 | Pedosphere2005，15，1： | 2 |
| 19 | Photothermal and pH dual-responsive self-healing coating for smart corrosion protection显示文摘A novel self-healing coating with photothermal and pH dual-responsive properties has been designed to protect carbon steel against corrosion by loading the stimuli-responsive microcapsules into a shape memory epoxy coating. The sandwich-like microcapsules were based on reduced graphene oxide/mesoporous silica(r GO@MS) assembled with a p H-responsive poly(N,N-dimethylaminoethyl methacrylate)(PDMAEMA) layer, and were loaded with benzotriazole(BTA) inhibitors(abbreviated as rGO@MS-P-BTA). Under near-infrared(NIR) light irradiation, the prominent photothermal effect of rGO could not only elevate the coating temperature to activate the shape memory effect and close the coating scratch, but also facilitate the release of corrosion inhibitors to suppress the corrosion activity. Moreover,the PDMAEMA as a p H-driven “gatekeeper” realized the controlled release of BTA from microcapsules at acid conditions. The surface morphology analysis, electrochemical impedance spectroscopy(EIS), and scanning electrochemical microscopy(SECM) were performed to evaluate the self-healing performance of the composite coatings. The results showed that the combination of NIR light and p H-responsive selfhealing effects endowed the coating with short healing time and prominent healing efficiency. | Yao Huang Panjun Wang Weimin Tan Wenkui Hao Lingwei Ma Jinke Wang Tong Liu Fan Zhang Chenhao Ren Wei Liu Dawei Zhang | 2022 | Journal of Materials Science & Technology2022，，12： | 2 |
