| 1 | Cation-vacancy induced Li+ intercalation pseudocapacitance at atomically thin heterointerface for high capacity and high power lithium-ion batteries显示文摘It is challenging to create cation vacancies in electrode materials for enhancing the performance of rechargeable lithium ion batteries (LIBs). Herein, we utilized a strong alkaline etching method to successfully create Co vacancies at the interface of atomically thin Co_(3−x)O_(4)/graphene@CNT heterostructure for high-energy/power lithium storage. The creation of Co-vacancies in the sample was confirmed by high-resolution scanning transmission electron microscope (HRSTEM), X-ray photoelectron spectroscopy (XPS) and electron energy loss near-edge structures (ELNES). The obtained Co_(3−x)O_(4)/graphene@CNT delivers an ultra-high capacity of 1688.2 mAh g^(−1) at 0.2 C, excellent rate capability of 83.7% capacity retention at 1 C, and an ultralong life up to 1500 cycles with a reversible capacity of 1066.3 mAh g^(−1). Reaction kinetic study suggests a significant contribution from pseudocapacitive storage induced by the Co-vacancies at the Co_(3−x)O_(4)/graphene@CNT interface. Density functional theory confirms that the Co-vacancies could dramatically enhance the Li adsorption and provide an additional pathway with a lower energy barrier for Li diffusion, which results in an intercalation pseudocapacitive behavior and high-capacity/rate energy storage. | Ding Yuan David Adekoya Yuhai Dou Yuhui Tian Hao Chen Zhenzhen Wu Jiadong Qin Linping Yu Jian Zhang Xianhu Liu Shi Xue Dou Shanqing Zhang | 2021 | Journal of Energy Chemistry2021，30，11： | 2 |
| 2 | Spatial Distribution and Seasonal Variation of Hypoxic Zone in the Eastern Equatorial Indian Ocean显示文摘The spatial distribution and seasonal variations of the hypoxic zone in the eastern equatorial Indian Ocean were investigated using survey data collected from four cruises from 2013 to 2018.Results showed that hypoxic zone occurred all year round in the eastern equatorial Indian Ocean,and it spread southward in the shape of a double tongue at two depths with one at subsurface centered at a depth of 150 m and the other in intermediate water centered at a depth of 800 m.The southward expansion and maximum thickness of the hypoxic zone were greatest in the spring inter-monsoon and least in the summer monsoon.The hypoxic zone originated from the southward expansion of the hypoxic water in the Bay of Bengal and its spatial distribution was driven by southward output flux of mid-deep(100–1000 m)hypoxic water from the Bay of Bengal.The hypoxia southward expansion was blocked near the equator in the subsurface layer,because of mixing with multiple zonal circulations(e.g.,Wyrtki Jets and the equatorial undercurrent),which meant that the hypoxic zone extended over a smaller area than in the intermediate water.These new findings will contribute to an improved understanding of the hypoxic zone and will contribute to circulation research,particularly about intermediate circulation in the eastern equatorial Indian Ocean. | XIE Linping WANG Baodong XIN Ming WANG Ying SUN Xia WEI Qinsheng LIU Lin YUAN Chao | 2023 | Journal of Ocean University of China2023，22，4： | 0 |
| 3 | Tax-Scheduler:An interactive visualization system for staff shifting and scheduling at tax authorities显示文摘Given a large number of applications and complex processing procedures,how to efficiently shift and schedule tax officers to provide good services to taxpayers is now receiving more attention from tax authorities.The availability of historical application data makes it possible for tax managers to shift and schedule staff with data support,but it is unclear how to properly leverage the historical data.To investigate the problem,this study adopts a user-centered design approach.We first collect user requirements by conducting interviews with tax managers and characterize their requirements of shifting and scheduling into time series prediction and resource scheduling problems.Then,we propose Tax-Scheduler,an interactive visualization system with a time-series prediction algorithm and genetic algorithm to support staff shifting and scheduling in the tax scenarios.To evaluate the effectiveness of the system and understand how non-technical tax managers react to the system with advanced algorithms and visualizations,we conduct user interviews with tax managers and distill several implications for future system design. | Linping Yuan Boyu Li Siqi Li Kam Kwai Wong Rong Zhang Huamin Qu | 2023 | Visual Informatics2023，7，2： | 0 |
