| 2 | Isothermal and nonisothermal crystallization kinetics of bio-sourced nylon 69显示文摘Bio-sourced nylon 69,one of promising engineering plastics,has a great potential in developing sustainable technology and various commercial applications.Isothermal and nonisothermal crystallization kinetics of nylon 69 is a base to optimize the process conditions and establish the structure–property correlations for nylon 69,and it is also highly bene ficial for successful applications of nylon products in industry.Isothermal and nonisothermal crystallization kinetics has been investigated by differential scanning calorimetry for nylon 69,bio-sourced even–odd nylon.The isothermal crystallization kinetics has been analyzed by the Avrami equation,the calculated Avrami exponent at various crystallization temperatures falls into the range of 2.28 and 2.86.In addition,the Avrami equation modi fied by Jeziorny and the equation suggested by Mo have been adopted to study the nonisothermal crystallization.The activation energies for isothermal and nonisothermal crystallization have also been determined.The study demonstrates that the crystallization model of nylon 69 might be a twodimensional(circular)growth at both isothermal and nonisothermal crystallization conditions.Furthermore,the value of the crystallization rate parameter(K)decreases signi ficantly but the crystallization half-time(t1/2)increases with the increase of the isothermal crystallization temperature.To nonisothermal crystallization,the crystallization rate increases as the cooling rate increases according to the analysis of Jeziorny's theory.The results of Mo's theory suggest that a faster cooling rate is required to reach a higher relative degree of crystallinity in a unit of time,and crystallization rate decreases when the relative degree of crystallinity increases at nonisothermal crystallization conditions. | Zhijuan Sun Xiao Wang Fei Guo Chunyue Jiang Qinmin Pan | 2016 | Chinese Journal of Chemical Engineering2016，24，5： | 5 |
| 3 | Adaptive Decentralized Output-Constrained Control of Single-Bus DC Microgrids显示文摘A single-bus DC microgrid can represent a wide range of applications. Control objectives of such systems include high-performance bus voltage regulation and proper load sharing among multiple distributed generators(DGs) under various operating conditions. This paper presents a novel decentralized control algorithm that can guarantee both the transient voltage control performance and realize the predefined load sharing percentages. First, the output-constrained control problem is transformed into an equivalent unconstrained one. Second, a two-step backstepping control algorithm is designed based on the transformed model for bus-voltage regulation. Since the overall control effort can be split proportionally and calculated with locally-measurable signals, decentralized load sharing can be realized. The control design requires neither accurate parameters of the output filters nor load measurement. The stability of the transformed systems under the proposed control algorithm can indirectly guarantee the transient bus voltage performance of the original system. Additionally, the high-performance control design is robust, flexible, and reliable. Switch-level simulations under both normal and fault operating conditions demonstrate the effectiveness of the proposed algorithm. | Jiangkai Peng Bo Fan Jiajun Duan Qinmin Yang Wenxin Liu | 2019 | IEEE/CAA Journal of Automatica Sinica2019，6，2： | 4 |

| 5 | Distributed Control of Multiple-Bus Microgrid With Paralleled Distributed Generators显示文摘A microgrid is hard to control due to its reduced inertia and increased uncertainties. To overcome the challenges of microgrid control, advanced controllers need to be developed.In this paper, a distributed, two-level, communication-economic control scheme is presented for multiple-bus microgrids with each bus having multiple distributed generators(DGs) connected in parallel. The control objective of the upper level is to calculate the voltage references for one-bus subsystems. The objectives of the lower control level are to make the subsystems' bus voltages track the voltage references and to enhance load current sharing accuracy among the local DGs. Firstly, a distributed consensusbased power sharing algorithm is introduced to determine the power generations of the subsystems. Secondly, a discrete-time droop equation is used to adjust subsystem frequencies for voltage reference calculations. Finally, a Lyapunov-based decentralized control algorithm is designed for bus voltage regulation and proportional load current sharing. Extensive simulation studies with microgrid models of different levels of detail are performed to demonstrate the merits of the proposed control scheme. | Bo Fan Jiangkai Peng Jiajun Duan Qinmin Yang Wenxin Liu | 2019 | IEEE/CAA Journal of Automatica Sinica2019，6，3： | 4 |

| 7 | A multi-functional binder for high loading sulfur cathode显示文摘Lithium sulfur(Li-S)batteries are the promising power sources,but their commercialization is significantly impeded by poor energy-storage functions at high sulfur loading.Here we report that such an issue can be effectively addressed by using a mussel-inspired binder comprised of chitosan grafted with catecholic moiety for sulfur cathodes.The resulting sulfur cathodes possess a high loading up to 12.2 mg cm-2 but also exhibit one of the best electrochemical properties among their counterparts.The excellent performances are attributed to the strong adhesion of the binder to sulfur particles,conducting agent,current collector,and polysulfide.The versatile adhesion effectively increases the sulfur loading,depresses the shuttle effect,and alleviates mechanical pulverization during cycling processes.The present investigation offers a new insight into high performance sulfur cathodes through a bio-adhesion viewpoint. | Ying Chu Ning Chen Ximing Cui Anmin Liu Liang Zhen Qinmin Pan | 2020 | Journal of Energy Chemistry2020，29，7： | 2 |

| 13 | Adaptive cubature Kalman filter with the estimation of correlation between multiplicative noise and additive measurement noise显示文摘Mobile robots are often subject to multiplicative noise in the target tracking tasks,where the multiplicative measurement noise is correlated with additive measurement noise.In this paper,first,a correlation multiplicative measurement noise model is established.It is able to more accurately represent the measurement error caused by the distance sensor dependence state.Then,the estimated performance mismatch problem of Cubature Kalman Filter(CKF)under multiplicative noise is analyzed.An improved Gaussian filter algorithm is introduced to help obtain the CKF algorithm with correlated multiplicative noise.In practice,the model parameters are unknown or inaccurate,especially the correlation of noise is difficult to obtain,which can lead to a decrease in filtering accuracy or even divergence.To address this,an adaptive CKF algorithm is further provided to achieve reliable state estimation for the unknown noise correlation coefficient and thus the application of the CKF algorithm is extended.Finally,the estimated performance is analyzed theoretically,and the simulation study is conducted to validate the effectiveness of the proposed algorithm. | Quanbo GE Zhongcheng MA Jinglan LI Qinmin YANG Zhenyu LU Hong LI | 2022 | Chinese Journal of Aeronautics2022，35，5： | 1 |

| 16 | The Digital Currency of China’s Central Bank:Digital Currency Electronic Payment(DCEP)显示文摘DCEP is the Chinese version of Central Bank Digital Currency(CBDC).It is the only legal digital currency in China and meets four conditions:(a)it is issued by the central bank;(b)it is digitized;(c)it is account and wallet based;(d)it is oriented towards the general public.As a retail central bank digital currency,it has three main technical features:a“tiered limit arrangement”(small-scale payments can be made anonymously while large-scale payments cannot),a“two-tier operating system”(as with the central bank-commercial bank traditional model),and a“dual offline payment system”(supporting both parties of the transaction).Compared with CBDCs in other countries,China’s DCEP has smaller economic impacts,more obscure strategic goals,and more scarce technical details.But its progress in testing is ahead of central banks of other countries.This article is based on public information and is intended to explain what DCEP is and why and how it was developed.It also offers suggestions for future research. | Chen Gengxuan Jia Qinmin Ling Hao Liu Yuyang | 2021 | Contemporary Social Sciences2021，6，4： | 1 |
