| 1 | γ-MnO2 nanorods/graphene composite as efficient cathode for advanced rechargeable aqueous zinc-ion battery显示文摘Aqueous Zn//MnO2 batteries are emerging as promising large-scale energy storage devices owing to their cost-effectiveness,high safety,high output voltage,and energy density.However,the MnO2 cathode suffers from intrinsically poor rate performance and rapid capacity deterioration.Here,we remove the roadblock by compositing MnO2 nanorods with highly conductive graphene,which remarkably enhances the electrochemical properties of the MnO2 cathode.Benefiting from the boosted electric conductivity and ion diffusion rate as well as the structural protection of graphene,the Zn//MnO2-graphene battery presents an admirable capacity of 301 mAh g^-1 at 0.5 A g^-1,corresponding to a high energy density of 411.6 Wh kg^-1.Even at a high current density of 10 A g^-1,a decent capacity of 95.8 mAh g^-1 is still obtained,manifesting its excellent rate property.Furthermore,an impressive power density of 15 kW kg^-1 is achieved by the Zn//MnO2-graphene battery. | Chao Wang Yinxiang Zeng Xiang Xiao Shijia Wu Guobin Zhong Kaiqi Xu Zengfu Wei Wei Su Xihong Lu | 2020 | Journal of Energy Chemistry2020，29，4： | 13 |
| 2 | Optimal operation strategy for distributed battery aggregator providing energy and ancillary services显示文摘The high penetration of distributed renewable energy raises a higher concern for the safe and economic operation of the smart grid. Distributed batteries equipped in demand-side can not only contribute to the reliability and security of the grid, but also make profits by participating in the electricity market, especially when distributed batteries are combined and operated by an aggregator.Considering the well-operated mechanism of performance based regulation(PBR) in the U.S. electricity market, it becomes increasingly lucrative for batteries to participate not only in energy markets for energy arbitrage, but also in ancillary service markets to provide regulation and peakload shaving services. In this study, distributed batteries are operated and coordinated by the aggregator, which simultaneously submits offers to the energy and the ancillary service markets as an individual entity. An optimaldecision model is formulated for the aggregator to determine the operation and bidding strategy for the distributed batteries by considering the characteristics of batteries,including the terms of capacity, efficiency and degradation cost. Finally, a numerical case is conducted to evaluate the benefits of the decision model. | Kangning LIU Qixin CHEN Chongqing KANG Wei SU Guobin ZHONG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，4： | 7 |
| 3 | Doppler estimating and compensating method based on phase显示文摘According to the Doppler sensitive of the phase coded pulse compression signal,a Doppler estimating and compensating method based on phase is put forward to restrain the Doppler sidelobes,raise the signal-to-noise ratio and improve measuring resolution.The compensation method is used to decompose the echo to amplitude and phase,and then compose the new compensated echo by the amplitude and the nonlinear component of the phase. Furthermore the linear component of the phase can be used to estimate the Doppler frequency shift.The computer simulation and the real data processing show that the method has accurately estimated the Doppler frequency shift, successfully restrained the energy leakage on spectrum,greatly increased the echo signal-to-noise ratio and improved the detection performance of the radio system in both time domain and frequency domain. | Chen Gang Zhao Zhengyu Nie Xuedong Shi Shuzhu Yang Guobin Su Fanfan | 2009 | Journal of Systems Engineering and Electronics2009，20，4： | 2 |

| 6 | Injectable silk sericin scaffolds with programmable shape-memory property and neuro-differentiation-promoting activity for individualized brain repair of severe ischemic stroke显示文摘Severe ischemic stroke damages neuronal tissue,forming irregular-shaped stroke cavities devoid of supporting structure.Implanting biomaterials to provide structural and functional support is thought to favor ingrowth of regenerated neuronal networks.Injectable hydrogels capable of in situ gelation are often utilized for stroke repair,but challenged by incomplete gelation and imprecise control over end-macrostructure.Injectable shape-memory scaffolds might overcome these limitations,but are not explored for stroke repair.Here,we report an injectable,photoluminescent,carbon-nanotubes-doped sericin scaffold(CNTs-SS)with programmable shape-memory property.By adjusting CNTs’concentrations,CNTs-SS′recovery dynamics can be mathematically calculated at the scale of seconds,and its shapes can be pre-designed to precisely match any irregular-shaped cavities.Using a preclinical stroke model,we show that CNTs-SS with the customized shape is successfully injected into the cavity and recovers its pre-designed shape to well fit the cavity.Notably,CNTs-SS’near-infrared photoluminescence enables non-invasive,real-time tracking after in vivo implantation.Moreover,as a cell carrier,CNTs-SS not only deliver bone marrow mesenchymal stem cells(BMSCs)into brain tissues,but also functionally promote their neuronal differentiation.Together,we for the first time demonstrate the feasibility of applying injectable shape-memory scaffolds for stroke repair,paving the way for personalized stroke repair. | Jian Wang Xiaolin Li Yu Song Qiangfei Su Xiakeerzhati Xiaohalati Wen Yang Luming Xu Bo Cai Guobin Wang Zheng Wang Lin Wang | 2021 | Bioactive Materials2021，6，7： | 0 |
| 7 | Optimal Location and Sizing of Distributed Generator via Improved Multi-Objective Particle Swarm Optimization in Active Distribution Network Considering Multi-Resource显示文摘In the framework of vigorous promotion of low-carbon power system growth as well as economic globalization,multi-resource penetration in active distribution networks has been advancing fiercely.In particular,distributed generation(DG)based on renewable energy is critical for active distribution network operation enhancement.To comprehensively analyze the accessing impact of DG in distribution networks from various parts,this paper establishes an optimal DG location and sizing planning model based on active power losses,voltage profile,pollution emissions,and the economics of DG costs as well as meteorological conditions.Subsequently,multiobjective particle swarm optimization(MOPSO)is applied to obtain the optimal Pareto front.Besides,for the sake of avoiding the influence of the subjective setting of the weight coefficient,the decisionmethod based on amodified ideal point is applied to execute a Pareto front decision.Finally,simulation tests based on IEEE33 and IEEE69 nodes are designed.The experimental results show thatMOPSO can achieve wider and more uniformPareto front distribution.In the IEEE33 node test system,power loss,and voltage deviation decreased by 52.23%,and 38.89%,respectively,while taking the economy into account.In the IEEE69 test system,the three indexes decreased by 19.67%,and 58.96%,respectively. | Guobin He Rui Su Jinxin Yang Yuanping Huang Huanlin Chen Donghui Zhang Cangtao Yang Wenwen Li | 2023 | Energy Engineering2023，120，9： | 0 |
| 8 | Facile cyclic ammonium salt with the smallest size for high performance electric double layer capacitors显示文摘The smallest cyclic ammonium salt reported to date, N,N-dimethylpyrrolidinium tetrafluoroborate (P11-BF4), was successively synthesized using a synthesis route without metal ions and halogen ions, then investigated as the electrolyte with Propylene carbonate in EDLCs. The electrochemical characteristics of EDLCs assembled by 1 mol/L P11-BF4/PC paired with activated carbon electrodes were compared to traditional electrolytes. P11-BF4 has proven to have superior voltage resistance by using cyclic voltammetry and constant current charge-discharge testing. Moreover, P11-BF4 exhibits a more brilliant rate performance due to its high conductivity. These results demonstrate that P11-BF4 is an ideal electrolyte to improve the energy density and power density of supercapacitors. | Chao Wang Jing Wang Xiang Xiao Guobin Zhong Shijia Wu Kaiqi Xu Wei Zhao Wei Su Jie Zeng Baojun Wu Weili Zhang Changcheng Wu Zhiqiang Shi | 2019 | Chinese Chemical Letters2019，30，6： | 0 |
