| 1 | In-situ fabricated anisotropic halide perovskite nanocrystals in polyvinylalcohol nanofibers: Shape tuning and polarized emission显示文摘We report an in-situ fabrication of halide perovskite (CH3NH3PbX3,CH3NH3 =methylammonium,MA,X =Cl,Br,I) nanocrystals in polyvinylalcohol (PVA) nanofibers (MAPbX3@PVA nanofibers) through electrospinning a perovskite precursor solution.With the content of the precursors increased,the resulting MAPbBr3 nanocrystals in PVA matrix changed the shape from ellipsoidal to pearl-like,and finely into rods-like.Optimized MAPbBr3@PVA nanofibers show strong polarized emission with the photoluminescence quantum yield of up to 72%.We reveal correlations between the shape of in-situ fabricated perovskite nanocrystals and the polarization degree of their emission by comparing experimental data from the single nanofiber measurements with theoretical calculations.Polarized emission of MAPbBr3@PVA nanofibers can be attributed to the dielectric confinement and quantum confinement effects.Moreover,nanofibers can be efficiently aligned by using parallel positioned conductor strips with an air gap as collector.A polarization ratio of 0.42 was achieved for the films of well-aligned MAPbBr3@PVA nanofibers with a macroscale size of 0.5 cm × 2 cm,which allows potential applications in displays,lasers,waveguides,etc. | Linghai Meng Changgang Yang Jingjia Meng Yongzhi Wang Yong Ge Ziqiang Shao Guofeng Zhang Andrey L.Rogach Haizheng Zhong | 2019 | Nano Research2019，12，6： | 9 |
| 2 | Property analysis of bistatic forward-looking SAR with arbitrary geometry显示文摘Bistatic forward-looking synthetic aperture radar(SAR) has many advantages and applications owing to its twodimensional imaging capability.There could be various imaging configurations because of the geometric flexibility of bistatic platforms,resulting in kinds of models built independently among which there could be some similar even the same motion features.Comprehensive research on such systems in a more comprehensive and general point of view is required to address their difference and consistency.Property analysis of bistatic forwardlooking SAR with arbitrary geometry is achieved including stripmap and spotlight modes on airborne platform,missile-borne platform,and hybrid platform of both.Emphasis is placed on azimuth space variance of some key parameters significantly affecting the subsequent imaging processing,based on which the frequency spectra are further described and compared considering respective features of different platforms for frequency imaging algorithm developing.Simulation results confirm the effectiveness and correctness of our analysis. | Ziqiang Meng Yachao Li Mengdao Xing Zheng Bao | 2016 | Journal of Systems Engineering and Electronics2016，27，1： | 2 |

| 9 | A New Kind of Subjective Trust Model显示文摘Based on the outstanding characteristics of Cloud Model on the process of transforming a qualitative concept to a set of quantitative numerical values, a formalized model of subjective trust is introduced by which we can transform between qualitative reputation and quantitative voting data. The present paper brings forward algorithms to compute direct trust and recommender trust. Further more, an effective similarity measuring method used to distinguish two users’ reputation on knowledge level is also proposed. The given model properly settles the uncertainty and fuzziness properties of subjective trust which is always the weakness of traditional subjective trust model, and provides a step in the direction of proper understanding and definition of human trust. | ZHANG Guangwei KANG Jianchu LUO Ziqiang MENG Xiangyi FANG Peici LI Deyi | 2006 | Wuhan University Journal of Natural Sciences2006，11，6： | 1 |

| 19 | Novel neutrophil extracellular trap-related mechanisms in diabetic wounds inspire a promising treatment strategy with hypoxia-challenged small extracellular vesicles显示文摘Neutrophil extracellular traps(NETs)have been considered a significant unfavorable factor for wound healing in diabetes,but the mechanisms remain unclear.The therapeutic application of small extracellular vesicles(sEVs)derived from mesenchymal stem cells(MSCs)has received considerable attention for their properties.Hypoxic preconditioning is reported to enhance the therapeutic potential of MSC-derived sEVs in regenerative medicine.Therefore,the aim of this study is to illustrate the detailed mechanism of NETs in impairment of diabetic wound healing and develop a promising NET-targeting treatment based on hypoxic pretreated MSC-derived sEVs(Hypo-sEVs).Excessive NETs were found in diabetic wounds and in high glucose(HG)-induced neutrophils.Further research showed that high concentration of NETs impaired the function of fibroblasts through activating endoplasmic reticulum(ER)stress.Hypo-sEVs efficiently promoted diabetic wound healing and reduced the excessive NET formation by transferring miR-17-5p.Bioinformatic analysis and RNA interference experiment revealed that miR-17-5p in Hypo-sEVs obstructed the NET formation by targeting TLR4/ROS/MAPK pathway.Additionally,miR-17-5p overexpression decreased NET formation and overcame NET-induced impairment in fibroblasts,similar to the effects of Hypo-sEVs.Overall,we identify a previously unrecognized NET-related mechanism in diabetic wounds and provide a promising NET-targeting strategy for wound treatment. | Ziqiang Chu Qilin Huang Kui Ma Xi Liu Wenhua Zhang Shengnan Cui Qian Wei Huanhuan Gao Wenzhi Hu Zihao Wang Sheng Meng Lige Tian Haihong Li Xiaobing Fu Cuiping Zhang | 2023 | Bioactive Materials2023，，9： | 1 |
