| 1 | Recent advances in flexible batteries:From materials to applications显示文摘Along with the rapid development of flexible and wearable electronic devices,there have been a strong demand for flexible power sources,which has in turn triggered considerable efforts on the research and development of flexible batteries.An ideal flexible battery would have not only just high electrochemical performance but also excellent mechanical deformabilities.Therefore,battery constituent components,chemistry systems,device configurations,and practical applications are all pivotal aspects that should be thoroughly considered.Herein,we systematically and comprehensively review the fundamentals and recent progresses of flexible batteries in terms of these important aspects.Specifically,we first discuss the requirements for constituent components,including the current collector,electrolyte,and separator,in flexible batteries.We then elucidate battery chemistry systems that have been studied for various flexible batteries,including lithium-ion batteries,non-lithium-ion batteries,and high-energy metal batteries.This is followed by discussions on the device configurations for flexible batteries,including onedimensional fiber-shaped,two-dimensional film-shaped,and three-dimensional structural batteries.Finally,we summarize recent efforts in exploring practical applications for flexible batteries.Current challenges and future opportunities for the research and development of flexible batteries are also discussed. | Fuwei Xiang Fang Cheng Yongjiang Sun Xiaoping Yang Wen Lu Rose Amal Liming Dai | 2023 | Nano Research2023，16，4： | 1 |

| 3 | Investigation on gas-solids hydrodynamics and matching enhancement in feedstock injection zone of double-level nozzle riser显示文摘With the development of current energy economy,it is necessary to improve the product distribution of fluid catalytic cracking process,which is achieved by a riser reactor with double-level of nozzles.The new riser is constructed by adding a level of secondary nozzle 0.5 m below the main nozzle of traditional riser.This paper investigates the gas-solids flow and oil-catalyst matching feature based on the optical fiber and tracer technologies.According to the distribution of solids holdup,particle velocity and dimen-sionless jet concentration,the feedstock injection zone can be divided into the upstream flow control region,the main flow control region,and the secondary flow control region in the radial direction.The size of the regions is changed by the jet gas velocity and axial height.There is a poor match of secondary nozzle jet to particles below the main nozzle.The jet gas from secondary nozzles can improve the matching effect of oil-catalyst near the wall and reduce the probability of coking above the main nozzle. | Xiuying Yao Jun Xu Yiping Fan Chunxi Lu Fuwei Sun | 2023 | Particuology2023，，4： | 0 |
| 4 | A new method to prepare calcium oxalate films for marble protection显示文摘Artificial calcium oxalate films have been applied to protect sculptures,monuments,and buildings made of marble due to their potential protective capacities.Unfortunately,artificially prepared calcium oxalate films are usually loose,and easy to peel off in contrast to the natural ones.In this paper,a new method was developed for the preparation of a compact and cohesive calcium oxalate film,using ethylene glycol as an additive.The morphology,elemental composition,structure,and crystal phase of the film were analyzed by SEM,EDX,IR,and XRD,and the protective effects were investigated by acid resistance test,while its adhesion to the underlying marble by the Scotch tape test.The porosity,water absorption,and color of treated marble were also assessed.The results showed that a calcium oxalate film with a compact structure,good adhesion,and a protective effect against acid rain can be successfully obtained by including ethylene glycol as an additive.With the new preparation method,a better bond between the stone and the film is obtained which contributes to solving the spalling problem of the artificial calcium oxalate films. | HE Lu JIANG YiJie MA WenTing LIU Yan YANG FuWei LU RuiCong WANG Lu ZHANG Kun CHEN XinNan GAO Xiang | 2023 | Science China(Technological Sciences)2023，66，8： | 0 |
| 5 | Similar Vertices and Isomorphism Detection for Planar Kinematic Chains Based on Ameliorated Multi-Order Adjacent Vertex Assignment Sequence显示文摘Isomorphism detection is fundamental to the synthesis and innovative design of kinematic chains(KCs).The detection can be performed accurately by using the similarity of KCs.However,there are very few works on isomorphism detection based on the properties of similar vertices.In this paper,an ameliorated multi-order adjacent vertex assignment sequence(AMAVS)method is proposed to seek out similar vertices and identify the isomorphism of the planar KCs.First,the specific definition of AMAVS is described.Through the calculation of the AMAVS,the adjacent vertex value sequence reflecting the uniqueness of the topology features is established.Based on the value sequence,all possible similar vertices,corresponding relations,and isomorphism discrimination can be realized.By checking the topological graph of KCs with a different number of links,the effectiveness and efficiency of the proposed method are verified.Finally,the method is employed to implement the similar vertices and isomorphism detection of all the 9-link 2-D0F(degree of freedom)planar KCs. | Liang Sun Zhizheng Ye Fuwei Lu Rongjiang Cui Chuanyu Wu | 2021 | Chinese Journal of Mechanical Engineering2021，34，1： | 0 |
