| 1 | Raman Spectroscopy and Imaging of Graphene显示文摘Graphene has many unique properties that make it an ideal material for fundamental studies as well as for potential applications.Here we review recent results on the Raman spectroscopy and imaging of graphene.We show that Raman spectroscopy and imaging can be used as a quick and unambiguous method to determine the number of graphene layers.The strong Raman signal of single layer graphene compared to graphite is explained by an interference enhancement model.We have also studied the effect of substrates,the top layer deposition,the annealing process,as well as folding(stacking order)on the physical and electronic properties of graphene.Finally,Raman spectroscopy of epitaxial graphene grown on a SiC substrate is presented and strong compressive strain on epitaxial graphene is observed.The results presented here are highly relevant to the application of graphene in nano-electronic devices and help in developing a better understanding of the physical and electronic properties of graphene. | Zhenhua Ni Yingying Wang Ting Yu Zexiang Shen | 2008 | Nano Research2008，1，4： | 51 |
| 2 | Coordinated optimal dispatch and market equilibrium of integrated electric power and natural gas networks with P2G embedded显示文摘As power to gas(P2 G) technology gradually matures, the coupling between electricity networks and natural gas networks should ideally evolve synergistically.With the intent of characterizing market behaviors of integrated electric power and natural gas networks(IPGNs)with P2 G facilities, this paper establishes a steady-state model of P2 G and constructs optimal dispatch models of an electricity network and a natural gas network separately. In addition, a concept of slack energy flow(SEF) is proposed as a tool for coordinated optimal dispatch between the two networks. To study how the market pricing mechanism affects coordinated optimal dispatch in an IPGN, a market equilibrium-solving model for an IPGN is constructed according to game theory, with a solution based on the Nikaido-Isoda function. Case studies are conducted on a joint model that combines the modified IEEE 118-node electricity network and the Belgian 20-node gas network.The results show that if the game between an electric power company and a natural gas company reaches market equilibrium, not only can both companies maximize their profits, but also the coordinated operation of the coupling units, i.e., gas turbines and P2 G facilities, will contribute more to renewable energy utilization and carbon emission reduction. | Zexing CHEN Yongjun ZHANG Tianyao JI Zexiang CAI Licheng LI Zhiheng XU | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，3： | 37 |
| 3 | Monolayer Graphene as a Saturable Absorber in a Mode-Locked Laser显示文摘我们证明单层 graphene 的内在的性质允许它当时,为锁模式的纤维激光充当一个更有效的可饱和的吸收器与多层的 graphene 相比。单层 graphene 的吸收能与多层的 graphene,有像皱纹的缺点的 graphene,或 functionalized graphene 相比在更低的刺激紧张被浸透。单层 graphene 有 65.9% 的显著地大的调整深度,而多层的 graphene 的调整深度极大地由于 nonsaturable 吸收被减少并且散布损失。微微秒 ultrafast 激光脉搏(1.23 ps ) 能作为一个可饱和的吸收器用单层 graphene 被产生。由于 ultrafast 松驰时间,更大的调整深度和单层 graphene 的更低的散布损失,它以塑造能力,脉搏稳定性,和产量精力的脉搏比多层的 graphene 更好表现。 | Qiaoliang Bao Han Zhang Zhenhua Ni Yu Wang Lakshminarayana Polavarapu Zexiang Shen Qing-Hua Xu Dingyuan Tang Kian Ping Loh | 2011 | Nano Research2011，4，3： | 25 |
| 4 | Application of computational fluid dynamic to model the hydraulic performance of subsurface flow wetlands显示文摘A subsurface flow wetland(SSFW)was simulated using a commercial computational fluid dynamic(CFD)code.The constructed media was simulated using porous media and the liquid resident time distribution(RTD)in the SSFW was obtained using the particle trajectory model.The effect of wetland configuration and operating conditions on the hydraulic performance of the SSFW were investigated.The results indicated that the hydraulic performance of the SSFW was predominantly affected by the wetland configuration.The hydraulic effciency of the SSFW with an inlet at the middle edge of the upper media was 0.584 and the best among the SSFWs with an inlet at the top,the middle,and the bottom edge of the upper media.The constructed media affected the hydraulic performance by the ratio(K)of the upper and lower media resistance.The selection of appropriate media resistance in the protection layer can improve the hydraulic effciency.When the viscous resistance coeffcient of the media in the protection layer changed from 2.315×105 to 1.200×108,the hydraulic effciency of the SSFW increased from 0.301 to 0.751.However,the effect of operating conditions on the hydraulic effciency of the SSFW was slight. | Liwei FAN Hai Reti Wenxing WANG Zexiang LU Zhiming YANG | 2008 | Journal of Environmental Sciences2008，20，12： | 17 |
| 5 | Stochastic Dynamic Economic Dispatch of Wind-integrated Electricity and Natural Gas Systems Considering Security Risk Constraints显示文摘As the proportion of wind power generation increases in power systems,it is necessary to develop new ways for wind power accommodation and improve the existing power dispatch model.The power-to-gas technology,which offers a new approach to accommodate surplus wind power,is an excellent way to solve the former.Hence,this paper proposes to involve power-to-gas technology in the integrated electricity and natural gas systems(IEGSs).To solve the latter,on one hand,a new indicator,the scale factor of wind power integration,is introduced into the wind power stochastic model to better describe the uncertainty of grid-connected wind power;on the other hand,for quantizing and minimizing the impact of the uncertainties of wind power and system loads on system security,security risk constraints are established for the IEGS by the conditional value-at-risk method.By considering these two aspects,an MILP formulation of a security-risk based stochastic dynamic economic dispatch model for an IEGS is established,and GUROBI obtained from GAMS is used for the solution.Case studies are conducted on an IEGS consisting of a modified IEEE 39-bus system and the Belgium 20-node natural gas system to examine the effectiveness of the proposed dispatch model. | Zexing Chen Gelan Zhu Yongjun Zhang Tianyao Ji Ziwen Liu Xiaoming Lin Zexiang Cai | 2019 | CSEE Journal of Power and Energy Systems2019，5，3： | 8 |

| 8 | Assessment of commutation failure in HVDC systems considering spatial-temporal discreteness of AC system faults显示文摘This paper presents a novel commutation failure(CF) assessment method considering the influences of voltage magnitude drop, phase shift, and spatial-temporal discreteness of AC system faults. The commutating voltage-time area is employed to analyze the spatial-temporal discreteness of AC system faults causing CF in high-voltage direct current systems, and the influences of fault position and fault time on CF are revealed. Based on this, a novel CF criterion is proposed, further considering the influence of voltage phase shift and the spatial-temporal discreteness. Then this research develops a new CF assessment method, which does not rely on electromagnetic transient simulations. A real case from the China Southern Power Grid is used to verify the practicability of the proposed method by comparing with simulation results obtained using PSCAD/EMTDC. | Huanhuan YANG Zexiang CAI Xiaohua LI Chaoyun YU | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，5： | 5 |

| 10 | In-plane coherent control of plasmon resonances for plasmonic switching and encoding显示文摘Considerable attention has been paid recently to coherent control of plasmon resonances in metadevices for potential applications in all-optical light-with-light signal modulation and image processing.Previous reports based on out-ofplane coherent control of plasmon resonances were established by modulating the position of a metadevice in standing waves.Here we show that destructive and constructive absorption can be realized in metallic nano-antennas through in-plane coherent control of plasmon resonances,which is determined by the distribution rule of electricalfield components of nano-antennas.We provide proof-of-principle demonstrations of plasmonic switching effects in a gold nanodisk monomer and dimer,and propose a plasmonic encoding strategy in a gold nanodisk chain.In-plane coherent control of plasmon resonances may open a new avenue toward promising applications in optical spectral enhancement,imaging,nanolasing,and optical communication in nanocircuits. | Liyong Jiang Tingting Yin Alexander M.Dubrovkin Zhaogang Dong Yuntian Chen Weijin Chen Joel K.W.Yang Zexiang Shen | 2019 | Light(Science & Applications)2019，8，1： | 2 |
| 11 | A soft actor-critic deep reinforcement learning method for multi-timescale coordinated operation of microgrids显示文摘This paper develops a multi-timescale coordinated operation method for microgrids based on modern deep rein-forcement learning.Considering the complementary characteristics of different storage devices,the proposed approach achieves multi-timescale coordination of battery and supercapacitor by introducing a hierarchical two-stage dispatch model.The first stage makes an initial decision irrespective of the uncertainties using the hourly predicted data to minimize the operational cost.For the second stage,it aims to generate corrective actions for the first-stage decisions to compensate for real-time renewable generation fluctuations.The first stage is formulated as a non-convex deterministic optimization problem,while the second stage is modeled as a Markov decision process solved by an entropy-regularized deep reinforcement learning method,i.e.,the Soft Actor-Critic.The Soft Actor-Critic method can efficiently address the exploration-exploitation dilemma and suppress variations.This improves the robustness of decisions.Simulation results demonstrate that different types of energy storage devices can be used at two stages to achieve the multi-timescale coordinated operation.This proves the effectiveness of the proposed method. | Chunchao Hu Zexiang Cai Yanxu Zhang Rudai Yan Yu Cai Bowei Cen | 2022 | Protection and Control of Modern Power Systems2022，7，1： | 2 |
| 12 | 复发性恶性综合征1例(英文)显示文摘Neuroleptic malignant syndrome(NMS) is a life-threatening neurologic complication associated with the use of neuroleptic agents and characterized by a distinctive clinical syndrome of fever,rigidity,autonomic nervous system dysfunction and mental status change.This report discusses the clinical presentation,possible etiology,pathogenesis and treatment of one case of recurrent NMS in a middle-aged woman with schizophrenia.NMS occurred after combined treatment with haloperidol and aripiprazole(the first episode) and,four years later,after combined treatment with haloperidol and clozapine(the second episode).This case highlights the need to be particularly cautious in the use of antipsychotic medications in patients with a history of NMS and,whenever possible,to avoid combined treatment with multiple antipsychotic medications in these patients. | Zexiang OUYANG Li CHU | 2013 | 上海精神医学2013，25，4： | 2 |
| 13 | Effects of Crystallinity and Defects of Layered Carbon Materials on Potassium Storage:A Review and Prediction显示文摘Layered carbon materials(LCMs)are composed of basic carbon layer units,such as graphite,soft carbon,hard carbon,and graphene.While they have been widely applied in the anode of potassium-ion batteries,the potassium storage mechanisms and performances of various LCMs are isolated and difficult to relate to each other.More importantly,there is a lack of a systematic understanding of the correlation between the basic microstructural unit(crystallinity and defects)and the potas-sium storage behavior.In this review,we explored the key structural factors affecting the potassium storage in LCMs,namely,the crystallinity and defects of carbon layers,and the key parameters(L_(a),L_(c),d_(002),I_(D)/I_(G))that characterize the crystallinity and defects of different carbon materials were extracted from various databases and literature sources.A structure–property database of LCMs was thus built,and the effects of these key structural parameters on the potassium storage properties,including the capacity,the rate and the working voltage plateau,were systematically analyzed.Based on the structure–prop-erty database analysis and the guidance of thermodynamics and kinetics,a relationship between various LCMs and potas-sium storage properties was established.Finally,with the help of machine learning,the key structural parameters of layered carbon anodes were used for the first time to predict the potassium storage performance so that the large amount of research data in the database could more effectively guide the scientific research and engineering application of LCMs in the future. | Xiaoxu Liu Tianyi Ji Hai Guo Hui Wang Junqi Li Hui Liu Zexiang Shen | 2022 | Electrochemical Energy Reviews2022，5，2： | 2 |
| 14 | Double Magnetic Separation-assisted Fluorescence Method for Sensitive Detection of Ochratoxin A显示文摘A double magnetic separation-assisted fluorescence method was developed to rapidly detect ochratoxin A(OTA). The OTA aptamer functionalized magnetic nanomaterial(Fe3O4-Aptanier) and complementary DNA conjugated nitrogen-doped graphene quantum dots(NGQDs-cDNA) were used in this assay. Aptamer could hybridize with cDNA, which induced tlie NGQDs-cDNA to bind onto Fe3O4-Aptamer, and resulted in the fluorescence quenching of NGQDs. After the addition of OTA, the NGQDs-cDNA could release into the solution, and resulted in the recovery of fluorescence signal of NGQDs consequently. By utilizing the magnetic separation, the unbonded NGQDs-cDNA and residual Fe3O4-Aptamer were removed, which significantly increased the fluorescence signal intensity. OTA could be detected in the linear range of 10 nmol/L to 2000 nmol/L, with a limit of detection as 0.66 mnol/L. The advantages of this method include simple operation, good selectivity and high sensitivity, and this method can be used for the rapid detection of ochratoxin A in wheat and com. | WANG Chengke TAN Rong LI Jiangyu ZHANG Zexiang | 2019 | Chemical Research in Chinese Universities2019，35，3： | 2 |
