| 1 | Hierarchically Correlated Equilibrium Q-learning for Multi-area Decentralized Collaborative Reactive Power Optimization显示文摘A hierarchically correlated equilibrium Q-learning(HCEQ)algorithm for reactive power optimization that considers carbon emission on the grid-side as an optimization objective,is proposed here.Based on the multi-area decentralized collaborative framework,the controllable variables in each region are divided into several optimization layers,which is an effective method for solving the limitations posed by dimensionality.The HCEQ provides constant information on the interaction between the state-action value function matrices,as well as on the cooperative game equilibrium among agents in each region.After acquiring the optimal value function matrix in the pre-learning process,HCEQ is able to quickly achieve an optimal solution online.Simulation of the IEEE 57-bus system is performed,which demonstrates that the proposed algorithm can effectively solve multi-area decentralized collaborative reactive power optimization,with the desired global search capabilities and convergence speed. | Min Tan Chuanjia Han Xiaoshun Zhang Lexin Guo Tao Yu | 2016 | CSEE Journal of Power and Energy Systems2016，2，3： | 3 |

| 3 | Fabrication of hierarchical MXene-based AuNPs-containing core-shell nanocomposites for high efficient catalysts显示文摘MXene is a new type of layered two-dimensional transition metal carbide materials differing from graphene, demonstrating intriguing chemical/physical properties. Here the chemical modification of MXene and next fabrication of core-shell MXene-COOH@(PEI/PAA)_n composites have been investigated. The obtained MXene-based composites were treated with gold nanoparticles to form MXene—COOH@(PEI/PAA)_n@AuNPs nanocomposites, and their catalytic properties for nitro-compounds were studied. The prepared nanocomposites demonstrated good catalytic activity and reproducibility, showing potential applications in composite catalysts and environmental fields. | Kaikai Li Tifeng Jiao Ruirui Xing Guodong Zou Qianran Zhao Jingxin Zhou Lexin Zhang Qiuming Peng | 2018 | Green Energy & Environment2018，3，2： | 0 |
| 4 | Zirconium Doped Hydrotalcite-based NiAl Mixed Oxides——Enhanced Performance for Adsorption of SO2 and NO显示文摘In the present study, the adsorptive behavior of zirconium doped hydrotalcite-based NiAl mixed oxides for reducing NO and SO2 was compared. According to tlie experimental results, the Zr^4+ cations were partially dissolved in crystalline NiO phase. With the addition of Zr, new centers for oxygen release and storage were formed, Lewis acid strength increased, and weakly and strongly alkaline sites were expanded. Moreover, in situ FTIR(Fourier transfonn infrared spectroscopy) investigation demonstrated that the amounts of surface bisulfite, sulfite, nitrite and nitrate spe? cies ofZrNiAlO were much more than those ofNiAlO. On the whole, this study concluded that the addition of Zr^4+ to NiAlO works to improve this compound as major absorbent for SO2 and NO. | ZHAO Ling ZHANG Yu LI Lexin XING Yating WANG Shuai Christopher J.

| 5 | Rational designed microstructure pressure sensors with highly sensitive and wide detection range performance显示文摘Highly sensitive pressure sensors are often deployed in human-machine interaction area,touch screen and human motion detection.However,there are still great challenges to fabricating with high sensitivity pressure sensor with wide-range detection.Herein,we developed a new strategy to fabricate a highly sensitive pressure sensor using sandpaper and improve its detection range using a sacrificial template.It was the fthatirst time to combine microstructure processing with the sacrificial template method to fabricate pressure sensor.The microstructure of sandpaper endowed the sensor with high sensitivity,and the elastic substrate enhanced the sensor ability to resist high pressure without being damaged.The fabricated sensor device exhibits a superior sensitivity of 39.077 kPa-1in the range from 50 kPa to 110 kPa with a broad linear response.Remarkably,high pressure ceiling(<160 kPa) ensures that the sponge could be applied in different practical conditions to monitor a range of subtle human motions including finger,wrist bending,and pulse.For applications,the sensor device can not only detect the foot stepping behavior(0.7 MPa) but also produce an obvious response to an extremely slight paper(9 mg,~0.9 Pa).The successful preparation of this micro-structured elastic sponge material provided new ideas for exploring its potential applications in pressure sensors and flexible wearable electronic devices. | Yimeng Ni Lexin Liu Jianying Huang Shuhui Li Zhong Chen Weiying Zhang Yuekun Lai | 2022 | Journal of Materials Science & Technology2022，，35： | 0 |
