| 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 | Injectable hybrid inorganic nanoscaffold as rapid stem cell assembly template for cartilage repair显示文摘Cartilage injuries are o?ten devastating and most cannot be cured because of the intrinsically low regenerative capacity of cartilage tissues. Although stem-cell therapy has shown enormous potential for cartilage repair, the therapeutic outcome has been restricted by low survival rates and poor chondrocyte differentiation in vivo. Here, we report an injectable hybrid inorganic(IHI) nanoscaffold that facilitates fast assembly, enhances survival and regulates chondrogenic differentiation of stem cells. IHI nanoscaffolds that strongly bind to extracellular matrix(ECM) proteins assemble stem cells through synergistic 3 D cell-cell and cell-matrix interactions, creating a favorable physical microenvironment for stem-cell survival and differentiation in vitro and in vivo. Additionally, chondrogenic factors can be loaded into nanoscaffolds with a high capacity, which allows deep, homogenous drug delivery into assembled 3 D stem-cell-derived tissues for effective control over the soluble microenvironment of stem cells. The developed IHI nanoscaffolds that assemble with stem cells are injectable. They also scavenge reactive oxygen species and timely biodegrade for proper integration into injured cartilage tissues. Implantation of stem-cell-assembled IHI nanoscaffolds into injured cartilage results in accelerated tissue regeneration and functional recovery. By establishing our IHI nanoscaffold-templated 3 D stem-cell assembly method, we provide a promising approach to better overcoming the inhibitory microenvironment associated with cartilage injuries and to advance current stem-cell-based tissue engineering. | Shenqiang Wang Letao Yang Bolei Cai Fuwei Liu Yannan Hou Hua Zheng Fang Cheng Hepeng Zhang Le Wang Xiaoyi Wang Qianxin Lv Liang Kong Ki-Bum Lee Qiuyu Zhang | 2022 | National Science Review2022，9，4： | 0 |
| 4 | GIS Applications and Development Trends in China显示文摘Since its conceptualization and creation in the 1960 s, Geographic Information System(GIS) has considerably developed. As a combination of traditional and modern technology, GIS has become an important part of modern management, decision-making, and command, contributing greatly to social progress and development. This article introduces the concepts of GIS, expounds on the GIS applications in China, and looks forward to developments in GIS technology in the future while reviewing the issues that GIS application development faces. GIS has evolved into an important branch of the information technology industry, with great vitality and broad development prospects. | DU Huishi YANG Yue SUN Hong SUN Baisheng CHENG Fuwei | 2015 | Journal of Landscape Research2015，7，1： | 0 |
| 5 | Positive effects of PVP in MIC:Preparation and characterization of Al-Core heterojunction fibers显示文摘The core-shell metastable intermolecular composites(MIC)have attracted much attention in the past few years due to their unique properties.Here,the preparation of Al-Core heterojunction fibers using PVP as a template is proposed.The nano-Al was directly added to the precursor solution of cupric acetate monohydrate(CAM)/Polyvinylpyrrolidone(PVP),and the initial Al@CAM/PVP fibers were obtained via electrospinning.The core-shell MIC fibers are then obtained by calcining the initial fibers.The morphology,structure,and composition of Al-core MIC fibers were characterized,that the energetic fibers calcined at 300℃,350℃,and 400℃have a core-shell structure with shell compositions CuxO and PVP,CuxO and Cu O,respectively.The energy release characteristics of Al-core MIC were investigated,and preliminary ignition tests were performed using an ignition temperature measuring instrument and a pulsed laser.The energetic fibers calcined at 300℃exhibited unique properties.The decomposition of PVP in the shell layer promoted exotherm,and a low-temperature exothermic peak was shown at 372-458℃.Lower ignition temperatures and higher flame heights were observed in the combustion tests than calcination at 350℃and 400℃.An unexpected result was that PVP can play a positive role in Al/CuO nanothermites.Simultaneously,this preparation method provided an idea for the integrated preparation of core-shell Al-Core MIC fibers and tuning the properties of MIC. | Fuwei Li Yue-ting Wang Cheng-ai Wang Yun Shen Ze-hua Zhang Jian Cheng Shuang-zhang Wu Ying-hua Ye Rui-qi Shen | 2023 | Defence Technology(防务技术)2023，19，1： | 0 |
| 6 | Mechanisms of water block removal by surfactant micellar solutions in low permeability reservoirs显示文摘The existing researches on surfactant micellar solutions mainly focus on the formulation optimization and core flooding test, and the types and mechanisms of cleanup additives suitable for low permeability reservoir remain unclear. The flowback efficiencies of different types of surfactant micellar solutions were evaluated by core experiments, a multi-level pore-throat system micromodel characterizing pore-throat structures of low permeability reservoir was made, and flooding and flowback experiments of brine and surfactant micellar solutions of different salinities were conducted with the micromodel to show the oil flowback process in micron pores under the effect of surfactant micellar solution visually and reveal the mechanisms of enhancing displacement and flowback efficiency of surfactant micellar solution. During the displacement and flowback of brine and low salinity surfactant micellar solution, many small droplets were produced, when the small droplets passed through pore-throats, huge percolation resistance was created due to Jamin’s effect, leading to the rise of displacement and flowback pressure differences and the drop of flowback efficiency. The surfactant micellar solutions with critical salinity and optimal salinity that were miscible with crude oil to form Winsor Ⅲ micro-emulsion didnot produce mass small droplets, so they could effectively reduce percolation resistance and enhance oil displacement and flowback efficiency. | LI Junjian LIU Ben GUO Cheng SU Hang YU Fuwei MA Mengqi WANG Lida JIANG Hanqiao | 2022 | Petroleum Exploration and Development2022，49，2： | 0 |
