| 1 | Solid-state intramolecular motions in continuous fibers driven by ambient humidity for fluorescent sensors显示文摘One striking feature of molecular rotors is their ability to change conformation with detectable optical signals through molecular motion when stimulated.However,due to the strong intermolecular interactions,synthetic molecular rotors have often relied on fluid environments.Here,we take advantage of the solid-state intramolecular motion of aggregation-induced emission(AIE)molecular rotors and one-dimensional fibers,developing highly sensitive optical fiber sensors that respond to ambient humidity rapidly and reversibly with observable chromatic fluorescence change.Moisture environments induce the swelling of the polymer fibers,activating intramolecular motions of AIE molecules to result in red-shifted fluorescence and linear response to ambient humidity.In this case,polymer fiber provides a process-friendly architecture and a physically tunable medium for the embedded AIE molecules to manipulate their fluorescence response characteristics.Assembly of sensor fibers could be built into hierarchical structures,which are adaptive to diverse-configuration for spatial-temporal humidity mapping,and suitable for device integration to build light-emitting sensors as well as touchless positioning interfaces for intelligence systems. | Yunmeng Jiang Yanhua Cheng Shunjie Liu Haoke Zhang Xiaoyan Zheng Ming Chen Michidmaa Khorloo Hengxue Xiang Ben Zhong Tang Meifang Zhu | 2021 | National Science Review2021,8,4: | 3 |
| 2 | Shape-stabilized phase change materials with high phase change enthalpy based on synthetic comb-like poly(acrylonitrile-co-ethylene glycol)for thermal management显示文摘Shape-stabilized poly(acrylonitrile-co-ethylene glycol)(PANEG) copolymer with comb-like structure was prepared via simple free-radical solution polymerization, where acrylic acid poly(ethylene glycol) methyl ether ester(MPEGA) and acrylonitrile(AN) were employed as monomers. Fourier transform infrared spectroscopy(FTIR), 1 H and 13 C nuclear magnetic resonance spectroscopy(1 H and 13 C NMR), wide-angle X-ray diffraction(WXAD) were used to characterize the chemical structure of resultant PANEG. In addition, the influences of MPEGA contents on energy storage performance, thermal reliability and thermal stability of PANEG materials were evaluated based on differential scanning calorimetry(DSC), polarizing optical microscopy(POM), thermal infrared imager and thermogravimetry analyzer(TG). The comb-like PANEG demonstrated a favorable temperature regulation performance and thermal reliability. With the increase of MPEGA contents, the enthalpy of PANEG increased, and when the content of MPEGA was 80 wt%, the phase change enthalpy of synthesized PANEG-80 reached to 106.70 J/g with a stable heat storage performance after 100 thermal cycling. Thermal infrared images and cooling curves revealed that synthetic PANEG could sustain a temperature in ranges of 22–31 °C for continuous 25 min, presenting excellent temperature regulation performance. Also, comb-like PANEG could be uniformly dissolved in dimethyl sulfoxide(DMSO),indicating that PANEG phase change fibers with potential applications in fields of intelligent thermoregulating textile and heat energy management could be obtained via one-step wet spinning. | Wei Chen Hengxue Xiang Yunmeng Jiang Sayed Yaseen Rashdi Meifang Zhu | 2017 | Science China Chemistry2017,60,11: | 3 |
| 3 | Mitigation of time-series InSAR turbulent atmospheric phase noise: A review显示文摘Synthetic Aperture Radar(SAR)interferometry is one of the most powerful remote sensing tools for ground deformation detection.However,tropospheric delay greatly limits the measurement accuracy of the InSAR technique.While vertically stratified tropospheric delays have been extensively investigated and well tackled,turbulent tropospheric phase noise still remains an intractable issue.In recent years,great efforts have been made to reduce the influence of turbulent atmospheric delay.This contribution is intended to provide a systematic review of the progress achieved in this field.First,it introduces the physical characteristics of atmospheric signals in interferograms.Then,a review of the main mitigation algorithms proposed in the literature is provided.In addition,the strengths and weaknesses of each approach are analyzed to provide guidance for choosing a suitable method accordingly.Finally,sug-gestions for resolving the challenging issues and an outlook for future research are given. | Zhiwei Li Meng Duan Yunmeng Cao Minzheng Mu Xin He Jianchao Wei | 2022 | Geodesy and Geodynamics2022,13,2: | 2 |

| 6 | Single-cell transcriptome analysis reveals the regulatory effects of artesunate on splenic immune cells in polymicrobial sepsis显示文摘Sepsis is characterized by a severe and life-threatening host immune response to polymicrobial infection accompanied by organ dysfunction.Studies on the therapeutic effect and mechanism of immunomodulatory drugs on the sepsis-induced hyperinflammatory or immunosuppression states of various immune cells remain limited.This study aimed to investigate the protective effects and underlying mechanism of artesunate(ART)on the splenic microenvironment of cecal ligation and puncture-induced sepsis model mice using single-cell RNA sequencing(scRNA-seq)and experimental validations.The scRNA-seq analysis revealed that ART inhibited the activation of pro-inflammatory macrophages recruited during sepsis.ART could restore neutrophils’chemotaxis and immune function in the septic spleen.It inhibited the activation of T regulatory cells but promoted the cytotoxic function of natural killer cells during sepsis.ART also promoted the differentiation and activity of splenic B cells in mice with sepsis.These results indicated that ART could alleviate the inflammatory and/or immunosuppressive states of various immune cells involved in sepsis to balance the immune homeostasis within the host.Overall,this study provided a comprehensive investigation of the regulatory effect of ART on the splenic microenvironment in sepsis,thus contributing to the application of ART as adjunctive therapy for the clinical treatment of sepsis. | Jiayun Chen Xueling He Yunmeng Bai Jing Liu Yin Kwan Wong Lulin Xie Qian Zhang Piao Luo Peng Gao Liwei Gu Qiuyan Guo Guangqing Cheng Chen Wang Jigang Wang | 2023 | Journal of Pharmaceutical Analysis2023,13,7: | 1 |

| 8 | Research on the Coupling between Agricultural Heritage and Tourism Industry: A Case Study of Jasmine and Tea Culture in Fuzhou显示文摘The integration of agricultural heritage and tourism industry contributes significantly to regional heritage protection,rural revitalization,and cultural inheritance.Based on the coupling coordination degree model,a quantitative research was conducted to study the integration of agricultural heritage in terms of the jasmine and tea culture system in Fuzhou with the local tourism industry.The results showed that both the development of Fuzhou's jasmine and tourism industries have advanced significantly and are currently leading in the country.However,they are not developing at the same pace.The results also showed that the coordination degree between Fuzhou5s jasmine and tourism industries have increased in recent years,with deepened mutual effects and improved coordination.Moreover,the coupling coordination degree has been rising over the past 13 years,with the coupling coordination level transforming from''extreme disorder''to'quality coordination,demonstrating a slow integration progress of Fuzhou's jasmine with the tourism industry at the early stage,but a sound development momentum at the later stage. | Yunmeng Ma Geying Lai | 2021 | Proceedings of Business and Economic Studies2021,4,5: | 1 |
| 9 | Polyoxometalate derived p-n heterojunction for optimized reaction interface and improved HER显示文摘MoS_(2) is a typical electrocatalyst for hydrogen evolution reaction(HER),but the HER activity is spoilt by intensive adsorption towards H^(*),which requires further improvement.For n-type MoS_(2),the construction of p-n heterojunction with p-type MoO_(3) can reverse this situation,because inner electronic field in p-n heterojunction can facilitate H^(*) desorption.Based on this hypothesis,p-n heterojunction is built between MoS_(2) and MoO_(3) with polyoxometalate compound as precursor.The obtained MoO_(3)/MoS_(2) exhibits excellent HER activity,which only requires 68 mV to obtain 10 mA/cm^(2).With MoO_(3)/MoS_(2) as cathode material and Zn slice as anode,Zn-H^(+)battery is assembled.Its open circuit voltage achieves 1.11 V with short circuit current 151.4 mA/cm^(2).The peak power density of this Zn-H^(+) battery reaches 47.6 mW/cm^(2).When discharge at 10 mA/cm^(2),the specific capacity and energy density reach 728 mAh/g and 759 Wh/kg.In this process,H_(2) production rate of Zn-H^(+) battery achieves 364μmol/h with Faradic efficiency 97.8%.It realizes H_(2) production and electricity generation simultaneously. | Xiaoli Cui Yunmeng Sun Xinxin Xu | 2023 | Chinese Chemical Letters2023,34,3: | 0 |
| 10 | Utility-optimal random access control in wireless multi-hop networks with queuing constraints显示文摘In this paper,a model of network utility maximization(NUM)is presented for random access control in multi-hop wireless networks.Diferent from the classical NUM framework,our model considers the queueing stability.We propose a distributed iterative prices and link probabilities adaption algorithm by using dual decomposition techniques,which only requires limited message passing,but converges to the global optimum of the total network utility.Numerical results and simulation comparison validate our conclusion. | TAN YunMeng ZHAO Yang LIAO ShengBin WU ZhuoHua | 2013 | Science China(Information Sciences)2013,56,10: | 0 |
| 11 | Dissection of cellular and molecular mechanisms of aristolochic acid-induced hepatotoxicity via single-cell transcriptomics显示文摘Background:Aristolochic acids(AAs),a class of carcinogenic and mutagenic natural products from Aristolochia and Asarum plants,are well-known to be responsible for inducing nephrotoxicity and urothelial carcinoma.Recently,accumulating evidence suggests that exposure to AAs could also induce hepatotoxicity and even hepatocellular carcinoma,though the mechanisms are poorly defined.Methods:Here,we aimed to dissect the underlying cellular and molecular mechanisms of aristolochic acid I(AAI)-induced hepatotoxicity by using advanced single-cell RNA sequencing(scRNA-seq)and proteomics techniques.We established the first single-cell atlas of mouse livers in response to AAI.Results:In hepatocytes,our results indicated that AAI activated NF-κB and STAT3 signaling pathways,which may contribute to the inflammatory response and apoptosis.In liver sinusoidal endothelial cells(LSECs),AAI activated multiple oxidative stress and inflammatory associated signaling pathways and induced apoptosis.Importantly,AAI induced infiltration of cytotoxic T cells and activation of proinflammatory macrophage and neutrophil cells in the liver to produce inflammatory cytokines to aggravate inflammation.Conclusions:Collectively,our study provides novel knowledge of AAs-induced molecular characteristics of hepatotoxicity at a singlecell level and suggests future treatment options for AAs associated hepatotoxicity. | Piao Luo Jiayun Chen Qian Zhang Fei Xia Chen Wang Yunmeng Bai Huan Tang Dandan Liu Liwei Gu Qingfeng Du Wei Xiao Chuanbin Yang Jigang Wang | 2022 | Precision Clinical Medicine2022,5,4: | 0 |
| 12 | Growth differentiation factor 11 promotes macrophage polarization towards M2 to attenuate myocardial infarction via inhibiting Notch1 signaling pathway显示文摘Background:Myocardial infarctions(MI)is a major threat to human health especially in people exposed to cold environment.The polarization of macrophages towards different functional phenotypes(M1 macrophages and M2 macrophages)is closely related to MI repairment.The growth differentiation factor 11(GDF11)has been reported to play a momentous role in inflammatory associated diseases.In this study,we examined the regulatory role of GDF11 in macrophage polarization and elucidated the underlying mechanisms in MI.Methods:In vivo,the mice model of MI was induced by permanent ligation of the left anterior descending coronary artery(LAD),and mice were randomly divided into the sham group,MI group,and MI+GDF11 group.The protective effect of GDF11 on myocardial infarction and its effect on macrophage polarization were verified by echocardiography,triphenyl tetrazolium chloride staining and immunofluorescence staining of heart tissue.In vitro,based on the RAW264.7 cell line,the effect of GDF11 in promoting macrophage polarization toward the M2 type by inhibiting the Notch1 Signaling pathway was validated by qRT-PCR,Western blot,and flow cytometry.Results:We found that GDF11 was significantly downregulated in the cardiac tissue of MI mice.And GDF11 supplementation can improve the cardiac function.Moreover,GDF11 could reduce the proportion of M1 macrophages and increase the accumulation of M2 macrophages in the heart tissue of MI mice.Furthermore,the cardioprotective effect of GDF11 on MI mice was weakened after macrophage clearance.At the cellular level,application of GDF11 could inhibit the expression of M1 macrophage(classically activated macrophage)markers iNOS,interleukin(IL)-1β,and IL-6 in a dose-dependent manner.In contrast,GDF11 significantly increased the level of M2 macrophage markers including IL-10,CD206,arginase 1(Arg1),and vascular endothelial growth factor(VEGF).Interestingly,GDF11 could promote M1 macrophages polarizing to M2 macrophages.At the molecular level,GDF11 significantly down-regulated the Notch1 signaling pathway,the activation of which has been demonstrated to promote M1 polarization in macrophages.Conclusions:GDF11 promoted macrophage polarization towards M2 to attenuate myocardial infarction via inhibiting Notch1 signaling pathway. | Manyu Gong Xuewen Yang Yaqi Wang Yanying Wang Dongping Liu Haodong Li Yunmeng Qu Xiyang Zhang Yanwei Zhang Han Sun Lei Jiao Ying Zhang | 2023 | Frigid Zone Medicine2023,3,1: | 0 |
| 13 | All‑Covalent Organic Framework Nanofilms Assembled Lithium‑Ion Capacitor to Solve the Imbalanced Charge Storage Kinetics显示文摘Free-standing covalent organic framework(COFs)nanofilms exhibit a remarkable ability to rapidly intercalate/de-intercalate Li^(+)in lithium-ion batteries,while simultaneously exposing affluent active sites in supercapacitors.The development of these nanofilms offers a promising solution to address the persistent challenge of imbalanced charge storage kinetics between battery-type anode and capacitor-type cathode in lithium-ion capacitors(LICs).Herein,for the first time,custom-made COFBTMB-TP and COFTAPB-BPY nanofilms are synthesized as the anode and cathode,respectively,for an all-COF nanofilm-structured LIC.The COFBTMB-TP nanofilm with strong electronegative–CF3 groups enables tuning the partial electron cloud density for Li^(+)migration to ensure the rapid anode kinetic process.The thickness-regulated cathodic COFTAPB-BPY nanofilm can fit the anodic COF nanofilm in the capacity.Due to the aligned 1D channel,2D aromatic skeleton and accessible active sites of COF nanofilms,the whole COFTAPB-BPY//COFBTMB-TP LIC demonstrates a high energy density of 318 mWh cm^(−3)at a high-power density of 6 W cm^(−3),excellent rate capability,good cycle stability with the capacity retention rate of 77%after 5000-cycle.The COFTAPB-BPY//COFBTMB-TP LIC represents a new benchmark for currently reported film-type LICs and even film-type supercapacitors.After being comprehensively explored via ex situ XPS,7Li solid-state NMR analyses,and DFT calculation,it is found that the COFBTMB-TP nanofilm facilitates the reversible conversion of semi-ionic to ionic C–F bonds during lithium storage.COFBTMB-TP exhibits a strong interaction with Li^(+)due to the C–F,C=O,and C–N bonds,facilitating Li^(+)desolation and absorption from the electrolyte.This work addresses the challenge of imbalanced charge storage kinetics and capacity between the anode and cathode and also pave the way for future miniaturized and wearable LIC devices. | Xiaoyang Xu Jia Zhang Zihao Zhang Guandan Lu Wei Cao Ning Wang Yunmeng Xia Qingliang Feng Shanlin Qiao | 2024 | Nano-Micro Letters2024,16,6: | 0 |

| 15 | Study on the water-tree ageing characteristics of polyethylene/organic montmorillonite and crosslinked polyethylene/organic montmorillonite nanocomposites显示文摘The dispersion state of nanoparticles affects the properties of composites,and the crosslinking process of polymers affects the dispersion state of nanoparticles.In order to investigate the effects of crosslinking behaviour on the water-tree ageing characteristics of nanocomposite dielectrics at the molecular level,polyethylene/organic-montmorillonite(PE/organic montmorillonite(OMMT))and crosslinked polyethylene/organic-montmorillonite(XLPE/OMMT)nanocomposites were prepared by the melt blending method,after which the accelerated water-tree ageing experiments were conducted using a needle electrode.Fourier transform infrared spectroscopy,differential scanning calorimetry,successive self-nucleation annealing and scanning electron microscope(SEM)tests were conducted to characterise the properties of the samples before and after watertree ageing.The results indicate that the initiation probability and the length of water trees in XLPE/OMMT are less than those in PE/OMMT.The carbonyl index in the watertree area of the two nanocomposites increases,indicating that the water-tree ageing is the result of electrochemical degradation.The crystallisability of the water-tree area degrades,decreasing the crystallinity and the lamellar thickness.The growth of water trees destroys molecular chains and crystal structures,which results in local cracks.There are many holes for the water tree growth in the PE/OMMT specimen.However,the crosslinked meshwork not only restricts the movement of macromolecular chains but also increases the stability of the lamellar barrier effect of OMMT.The combination of the two effects significantly improves the water-tree resistance of the XLPE/OMMT nanocomposite. | Xiufeng Li Yunmeng Yang Qiang Wang Yuan Gao Wei Zhang Zhengdi Liu | 2023 | High Voltage2023,8,2: | 0 |
| 16 | On Reading Theories and Instruction Model显示文摘We have come to know comprehension better by studying the nature and characteristics of reading processes and by weighing the pros and cons of different reading theories and their influence on the teaching of reading. But in China, unfortunately, few achievements have been made in the field of reading theory research. Thus, in order to ameliorate our reading teaching, it is urgent for us to set up our own system of reading theories. The author, after studying carefully the present reading models in China and by absorbing the quintessence of foreign reading theories, ventures to suggest the “discourse word discourse” model. The model gives full thought to the characteristics of Chinese college students and thus suits a reading classroom in China better. However, the comprehension factors involved in the model are far from exhaustive and the model itself leaves much room for modification and addition.\; | Zhu Yunmeng \ \ | 2000 | 首都师范大学学报(社会科学版)2000,,S2: | 0 |

| 18 | Quantifying Multi-hazards and Impacts Over Different Growth Periods of Maize:A Study Based on Index Construction显示文摘Owing to the complexity and variability of global climate,the study of extreme events to ensure food security is particularly critical.The standardized precipitation requirement index(SPRI)and chilling injury index(I_(Ci))were introduced using data from agrometeorological stations on the Songliao Plain between 1981 and 2020 to identify the spatial and temporal variability of drought,waterlogging,and low-temperature cold damage during various maize growth periods.Compound drought and low-temperature cold damage events(CDLEs)and compound waterlogging and low-temperature cold damage events(CWLEs)were then identified.To measure the intensity of compound events,the compound drought and low-temperature cold damage magnitude index(CDLMI),and compound waterlogging and low-temperature cold damage magnitude index(CWLMI)were constructed by fitting marginal distributions.Finally,the effects of extreme events of various intensities on maize output were examined.The findings demonstrate that:(1)There were significant differences in the temporal trends of the SPRI and ICiduring different maize growth periods.Drought predominated in the middle growth period(MP),waterlogging predominated in the early growth period(EP)and late growth period(LP),and both drought and waterlogging tended to increase in intensity and frequency.The frequency of low-temperature cold damage showed a decreasing trend in all periods.(2)The CDLMI and CWLMI can effectively determine the intensity of CDLEs and CWLEs in the study area;these CDLEs and CWLEs had higher intensity and frequency in the late growth period.(3)Compared to single events,maize relative meteorological yield had a more significant negative correlation with the CDLMI and CWLMI. | Dan Chen Ying Guo Rui Wang Yunmeng Zhao Kaiwei Li Jiquan Zhang Xingpeng Liu Zhijun Tong Chunli Zhao | 2023 | International Journal of Disaster Risk Science2023,14,5: | 0 |
