| 1 | A Comprehensive Approach for the Clustering of Similar-Performance Cells for the Design of a Lithium-Ion Battery Module for Electric Vehicles显示文摘An energy-storage system comprised of lithium-ion battery modules is considered to be a core component of new energy vehicles,as it provides the main power source for the transmission system.However,manufacturing defects in battery modules lead to variations in performance among the cells used in series or parallel configuration.This variation results in incomplete charge and discharge of batteries and non-uniform temperature distribution,which further lead to reduction of cycle life and battery capacity over time.To solve this problem,this work uses experimental and numerical methods to conduct a comprehensive investigation on the clustering of battery cells with similar performance in order to produce a battery module with improved electrochemical performance.Experiments were first performed by dismantling battery modules for the measurement of performance parameters.The kmeans clustering and support vector clustering(SVC)algorithms were then employed to produce battery modules composed of 12 cells each.Experimental verification of the results obtained from the clustering analysis was performed by measuring the temperature rise in the cells over a certain period,while air cooling was provided.It was found that the SVC-clustered battery module in Category 3 exhibited the best performance,with a maximum observed temperature of 32℃.By contrast,the maximum observed temperatures of the other battery modules were higher,at 40℃for Category 1(manufacturer),36℃for Category 2(manufacturer),and 35℃for Category 4(k-means-clustered battery module). | Wei Li Siqi Chen Xiongbin Peng Mi Xiao Liang Gao Akhil Garg Nengsheng Bao | 2019 | Engineering2019，5，4： | 4 |
| 2 | A Fast Charging–Cooling Coupled Scheduling Method for a Liquid Cooling-Based Thermal Management System for Lithium-Ion Batteries显示文摘Efficient fast-charging technology is necessary for the extension of the driving range of electric vehicles.However,lithium-ion cells generate immense heat at high-current charging rates.In order to address this problem,an efficient fast charging–cooling scheduling method is urgently needed.In this study,a liquid cooling-based thermal management system equipped with mini-channels was designed for the fastcharging process of a lithium-ion battery module.A neural network-based regression model was proposed based on 81 sets of experimental data,which consisted of three sub-models and considered three outputs:maximum temperature,temperature standard deviation,and energy consumption.Each sub-model had a desirable testing accuracy(99.353%,97.332%,and 98.381%)after training.The regression model was employed to predict all three outputs among a full dataset,which combined different charging current rates(0.5C,1C,1.5C,2C,and 2.5C(1C=5 A))at three different charging stages,and a range of coolant rates(0.0006,0.0012,and 0.0018 kg·s^(-1)).An optimal charging–cooling schedule was selected from the predicted dataset and was validated by the experiments.The results indicated that the battery module’s state of charge value increased by 0.5 after 15 min,with an energy consumption lower than 0.02 J.The maximum temperature and temperature standard deviation could be controlled within 33.35 and 0.8C,respectively.The approach described herein can be used by the electric vehicles industry in real fast-charging conditions.Moreover,optimal fast charging-cooling schedule can be predicted based on the experimental data obtained,that in turn,can significantly improve the efficiency of the charging process design as well as control energy consumption during cooling. | Siqi Chen Nengsheng Bao Akhil Garg Xiongbin Peng Liang Gao | 2021 | Engineering2021，7，8： | 3 |
| 3 | Phosphor-free single chip GaN-based white light emitting diodes with a moderate color rendering index and significantly enhanced communications bandwidth显示文摘To achieve high quality lighting and visible light communication(VLC)simultaneously,Ga N based white light emitting diodes(WLEDs)oriented for lighting in VLC has attracted great interest.However,the overall bandwidth of conventional phosphor converted WLEDs is limited by the long lifetime of phosphor,the slow Stokes transfer process,the resistance-capacitance(RC)time delay,and the quantum-confined Stark effect(QCSE).Here by adopting a self-assembled In Ga N quantum dots(QDs)structure,we have fabricated phosphor-free single chip WLEDs with tunable correlated color temperature(CCT,from 1600 K to 6000 K),a broadband spectrum,a moderate color rendering index(CRI)of 75,and a significantly improved modulation bandwidth(maximum of150 MHz)at a low current density of 72 A∕cm^2.The broadband spectrum and high modulation bandwidth are ascribed to the capture of carriers by different localized states of In Ga N QDs with alleviative QCSE as compared to the traditional In Ga N/Ga N quantum well(QW)structures.We believe the approach reported in this work will find its potential application in Ga N WLEDs and advance the development of semiconductor lighting-communication integration. | Rongqiao Wan Xiang Gao Liancheng Wang Shuo Zhang Xiongbin Chen Zhiqiang Liu Xiaoyan Yi Junxi Wang Junhui Li Wenhui Zhu Jinmin Li | 2020 | Photonics Research2020，8，7： | 3 |
| 4 | Surface tidal currents in the open sea area to the east of the Zhoushan Islands measured with high frequency surface wave radar显示文摘Based on the quasi-harmonic analysis of 11 d vector ocean currents obtained from two high frequency surface wave radars located at Zhujiajian Island and Shengshan Island,the spatial distribution characteristics of surface tidal currents in the open sea area to the east of the Zhoushan Islands of Zhejiang Province,China are studied.The following conclusions are drawn from the analysis:the tidal current pattern in the open sea area to the east of Zhoushan Islands is primarily regular semidiurnal,which is significantly affected by the shallow water constituents.The directions of the major axes of tidal current ellipses of M2lie approximately in the NW-SE direction.With the increasing of distance away from the coast,the directions of the tidal current ellipses gradually shift toward the E-W direction.The tidal currents are mainly reversing currents.The spatial distribution of probable maximum current velocities decreases gradually from northeast to southwest which is basically in accordance with the spatial distribution of measured maximum current velocities.The residual currents near the coast are larger than those far away from the coast.The directions of the residual currents are basically north by east,and the angle to the due north increases gradually with the increasing distance away from the coast.The topography shows a certain impact on the spatial distribution of shallow water constituents,the rotation of tidal currents,the probable maximum currents and the residual currents. | SHEN Zhiben WU Xiongbin FEI Yuejun XU Xing'an CHEN Xiaofeng | 2013 | Acta Oceanologica Sinica2013，32，10： | 2 |

| 7 | Observer-based boundary control for an asymmetric output-constrained flexible robotic manipulator显示文摘Dear editor,With the rapid development of robotics, flexible robotic manipulators have played an important role in industrial production and manufacture because of their lightweight, higher operation speed and better energy efficiency [1]. However, flexible materials will result in vibration. Besides, in practical applications, external disturbances and constraints caused by environmental factors or technique requirements diffusely exist, which will affect the operation accuracy of the manipulators. Thus, we focus on the angle tracking and vibration problem of the flexible robotic manipulator with external disturbances and output constraints. | Yu LIU Xiongbin CHEN Yanfang MEI Yilin WU | 2022 | Science China(Information Sciences)2022，65，3： | 1 |

| 10 | Numerical Research on Effect of Sudden Cross-Section Expansion on Detonation Initiation显示文摘Numerical simulation has been performed to investigate the DDT(Deflagration-to-Detonation Transition)mechanism by solving fully compressible reactive flow for hydrogen/air mixtures in tube with sudden cross-section expansion.The results reveal the acceleration action of abrupt cross-section on DDT,which is validated by comparing the run up distance and time with corresponding long annular tube and single tube.Detailed discussion of flow field variations finds that the DDT process in cross-section abrupt tube can be divided into three stages(flame acceleration,transition to detonation,and detonation propagation stages respectively)according to different flame modes.Particularly,it is found that formation of vortex could accelerate DDT by promoting turbulent mixing of hot products and cold reactants.Further comparative analysis on DDT characteristics of cross-section abrupt tube with different annular gap lengths shows that different mechanisms dominate in the single tube zone.The conclusions in present study support the cross-section abrupt tube as a means to enhance DDT and provide an alternative potential in practical pre-detonation initiator and pulse detonation engine applications. | JIA Xiongbin ZHAO Ningbo MAXWELL Brian CHEN Xiang ZHENG Hongtao | 2022 | Journal of Thermal Science2022，31，5： | 0 |
| 11 | A multidimensional platform of patient-derived tumors identifies drug susceptibilities for clinical lenvatinib resistance显示文摘Lenvatinib,a second-generation multi-receptor tyrosine kinase inhibitor approved by the FDA for first-line treatment of advanced liver cancer,facing limitations due to drug resistance.Here,we applied a multidimensional,high-throughput screening platform comprising patient-derived resistant liver tumor cells(PDCs),organoids(PDOs),and xenografts(PDXs)to identify drug susceptibilities for conquering lenvatinib resistance in clinically relevant settings.Expansion and passaging of PDCs and PDOs from resistant patient liver tumors retained functional fidelity to lenvatinib treatment,expediting drug repurposing screens.Pharmacological screening identified romidepsin,YM155,apitolisib,NVP-TAE684 and dasatinib as potential antitumor agents in lenvatinib-resistant PDC and PDO models.Notably,romidepsin treatment enhanced antitumor response in syngeneic mouse models by triggering immunogenic tumor cell death and blocking the EGFR signaling pathway.A combination of romidepsin and immunotherapy achieved robust and synergistic antitumor effects against lenvatinib resistance in humanized immunocompetent PDX models.Collectively,our findings suggest that patient-derived liver cancer models effectively recapitulate lenvatinib resistance observed in clinical settings and expedite drug discovery for advanced liver cancer,providing a feasible multidimensional platform for personalized medicine. | Lei Sun Arabella H.Wan Shijia Yan Ruonian Liu Jiarui Li Zhuolong Zhou Ruirui Wu Dongshi Chen Xianzhang Bu Jingxing Ou Kai Li Xiongbin Lu Guohui Wan Zunfu Ke | 2024 | Acta Pharmaceutica Sinica B2024，14，1： | 0 |
| 12 | Spatial Distribution Characteristics of Surface Tidal Currents in the Southwest of Taiwan Strait显示文摘This study was conducted on the spatial distribution characteristics of surface tidal currents in the southwestern Taiwan Strait based on the quasi-harmonic analysis of current data obtained by two high frequency surface wave radar(HFSWR) systems. The analysis shows that the tidal current pattern in the southwestern Taiwan Strait is primarily semi-diurnal and influenced significantly by shallow water constituents. The spatial distribution of tidal current ellipses of M2 is probably affected by the interaction between two different systems of tide wave, one from the northern mouth of Taiwan Strait and the other from the Bashi Channel. The directions of the major axes of M2 tidal current ellipses coincide roughly with the axis of the Taiwan Strait. The spatial distribution of the magnitudes of the probable maximum current velocity(PMCS) shows gradual increase of the velocity from northeast to southwest, which is in accordance with the spatial distribution of the measured maximum current velocity(MMCS). The directions of the residual currents are in accordance with the direction of the prevailing monsoon wind at the Taiwan Strait and the direction of the Taiwan warm current during summer. The bathymetry also shows a significant effect on the spatial distribution characteristics of tidal currents. | SHEN Zhiben WU Xiongbin LIN Hang CHEN Xiaofeng XU Xing’an LI Lun | 2014 | Journal of Ocean University of China2014，13，6： | 0 |

| 14 | Metal-to-ligand charge transfer chirality-based sensing of mercury ions显示文摘Chiral ligand conjugated transition metal oxide nanoparticles(NPs) are a promising platform for chiral recognition, biochemical sensing, and chiroptics. Herein, we present chirality-based strategy for effective sensing of mercury ions via ligand-induced chirality derived from metal-to-ligand charge transfer(MLCT) effects. The ligand competition effect between molybdenum and heavy metal ions such as mercury is designated to be essential for MLCT chirality. With this know-how, mercury ions, which have a larger stability constant(Kf) than molybdenum, can be selectively identified and quantified with a limit of detection(LOD) of 0.08 and 0.12 nmol/L for D-cysteine and L-cysteine(Cys) capped Mo O2 NPs. Such chiral chemical sensing nanosystems would be an ideal prototype for biochemical sensing with a significant impact on the field of biosensing, biological systems,and water research-based nanotoxicology. | XIONGBIN WANG QIUSHI WANG YULONG CHEN JIAGEN LI RUIKUN PAN XING CHENG KAR WEI NG XI ZHU TINGCHAO HE JIAJI CHENG ZIKANG TANG RUI CHEN | 2021 | Photonics Research2021，9，2： | 0 |
