| 4 | Preparation and properties of temperature sensitive paint based on Eu(DBM)_3 phen as probe molecule显示文摘Probe molecule Eu(DBM)3 phen is made up of europium oxide(Eu_2 O_3),dibenzoylmethane(DBM) and1,10-phenanthroline(phen). The temperature sensitive paint(TSP) was compounded by the polymerization of the probe molecule, methyl methacrylate(MMA) and the initiator of benzoyl peroxide(BPO).The structure, morphology, luminescence property of probe molecule and the temperature quenching property of the temperature sensitive paint(TSP) were characterized by infrared spectrometer, UV-vis spectrometer, scanning electron microscopy and fluorescence spectrometer respectively. The infrared spectrum and UV-vis spectra show that Eu and DBM form six membered rings, and Eu-O coordinate bonds form. The nanocrystals are in sphere-like morphology with an average size of approximately100 nm. Fluorescence spectra present that the performance of temperature quenching is excellent,what's more, TSP sample has different temperature sensitivity in various temperature scope. Particularly,under excitation of 286 nm, TSP has a highest temperature sensitivity between 50 and 60 ℃, and the strongest fluorescence emission reaches a peak(615 nm). It indicated that probe molecule(Eu(DBM)_3 phen) has strong luminescent intensity and the temperature quenching properties of Eu(DBM)_3 phen/PMMA is good. | Siyu Lu Jing Sun Yuan Wang Wensheng Yu Mengting Sun Siyuan Cui | 2018 | Journal of Rare Earths2018，36，6： | 8 |
| 5 | Effect of Ginkgo biloba leaf extract on cerebral cortex amino acid levels in cerebral ischemia model rats显示文摘OBJECTIVE: To investigate the effect of Ginkgo biloba leaf extract on amino acid levels in the cerebral cortex of cerebral ischemia model rats induced by middle cerebral artery occlusion(MCAO).METHODS: A rat model of cerebral ischemia was established by MCAO. Male rats were divided into a negative control group(Control), a sham-operated group(Sham), an ischemic group(MCAO), and an ischemic group treated with Ginkgo biloba leaf extract(MCAO_D). All groups were divided into two subgroups with occlusion times of 12 and 24 h, respectively. The levels of 18 endogenous amino acids in the cerebral cortex were quantified by triple quadrupole-liquid chromatography-mass spectrometry.RESULTS: Compared with the MCAO group, behavioral performance, neurological deficit score, and cerebral infarct volume were significantly improved in the MCAO_D group(P < 0.05, P < 0.01). Compared with the sham group, the levels of 17 amino acids in the cerebral cortex were markedly changed in the MCAO group. The levels of Alanine(Ala), Isoleucine(Ile), Glutamic acid(Glu), Serine(Ser), Valine(Val), Phenylalanine(Phe), Proline(Pro),Threonine(Thr), Lysine(Lys), Tyrosine(Tyr), Hydroxyproline(Hyp), Arginine(Arg), Leucine(Leu),Tryptophan(Trp), and Glycine(Gly) were increased(P < 0.001, P < 0.05), while levels of Gln and Tau were decreased(P < 0.001, P < 0.05). Compared with the MCAO group, Ginkgo biloba extract treatment in the MCAO_D group significantly down-regulated the levels of 11 amino acids, especially those of Arg, Thr, and Ser in 12 or 24 h.CONCLUSION: Injection of Ginkgo biloba leaf extract has a therapeutic effect on model rats with MCAO-induced cerebral ischemia by acting on amino acids in the cerebral cortex. This effect might be associated with the regulation of amino acid metabolism in the cerebral cortex. | Cui Yiran Wu Hongwei Liu Mengting Qin Haijiao Liu Xin Yang Hongjun | 2018 | Journal of Traditional Chinese Medicine2018，38，5： | 8 |
| 6 | Ginsenoside Rg1 ameliorates bloodebrain barrier disruption and traumatic brain injury via attenuating macrophages derived exosomes miR-21 release显示文摘During the traumatic brain injury(TBI),improved expression of circulatory miR-21 serves as a diagnostic feature.Low levels of exosome-miR-21 in the brain can effectively improve neuroinflammation and bloodebrain barrier(BBB)permeability,reduce nerve apoptosis,restore neural function and ameliorate TBI.We evaluated the role of macrophage derived exosomes-miR-21(M-Exos-miR-21)in disrupting BBB,deteriorating TBI,and Rg1 interventions.IL-1β-induced macrophages(ⅡA)-Exos-miR-21 can activate NF-kB signaling pathway and induce the expressions of MMP-1,-3 and-9 and downregulate the levels of tight junction proteins(TJPs)deteriorating the BBB.Rg1 reduced miR-21-5 p content in ⅡA-Exos(RⅡA-Exos).The interaction of NMIIAe HSP90 controlled the release of Exos-miR-21,this interaction was restricted by Rg1.Rg1 could inhibit the Exos-miR-21 release in peripheral blood flow to brain,enhancing TIMP3 protein expression,MMPs proteolysis,and restricting TJPs degradation thus protected the BBB integrity.Conclusively,Rg1 can improve the cerebrovascular endothelial injury and hold the therapeutic potential against TBI disease. | Kefeng Zhai Hong Duan Wei Wang Siyu Zhao Ghulam Jilany Khan Mengting Wang Yuhan Zhang Kiran Thakur Xuemei Fang Chao Wu Jianbo Xiao Zhaojun Wei | 2021 | Acta Pharmaceutica Sinica B2021，11，11： | 6 |

Therefore, it is important to improve the heat dissipation and EMI shielding performancein device packaging for the steady operation of electronic products. In recent years, due to its intrinsic superior thermal conductivity, proper electrical conductivity, light-weight, and structural adjustability,graphene has been widely used as high thermal and conductive fillers incorporated in the polymer matrix to improve the thermal conductivity and electrical conductivity of composites. This review concludesthe recent development of graphene/polymer composites by using graphene as fillers to improve thethermal conductivity and EMI shielding effectiveness (EMI SE). The structure of graphene embedded inthe composites varies from zero-dimension (0D), one-dimension (1D) to two-dimensions (2D). Moreover,highly thermally and electrically conductive fillers with different dimensions were also modified on thegraphene to improve the composite performance. Finally, this review also makes prospects for the development trend of graphene/polymer composites with high thermal conductivity and EMI SE in the future. | Xue Tan Qilong Yuan Mengting Qiu Jinhong Yu Nan Jiang Cheng-Te Lin Wen Dai | 2022 | Journal of Materials Science & Technology2022，，22： | 5 |
| 9 | Ultra-sensitive Nanoprobe Modified with Tumor Cell Membrane for UCL/MRI/PET Multimodality Precise Imaging of Triple-Negative Breast Cancer显示文摘Triple-negative breast cancer(TNBC)is a subtype of breast cancer in which the estrogen receptor and progesterone receptor are not expressed,and human epidermal growth factor receptor 2 is not amplified or overexpressed either,which make the clinical diagnosis and treatment very challenging.Molecular imaging can provide an effective way to diagnose TNBC.Upconversion nanoparticles(UCNPs),are a promising new generation of molecular imaging probes.However,UCNPs still need to be improved for tumor-targeting ability and biocompatibility.This study describes a novel probe based on cancer cell membrane-coated upconversion nanoparticles(CCm-UCNPs),owing to the low immunogenicity and homologous-targeting ability of cancer cell membranes,and modified multifunctional UCNPs.This probe exhibits excellent performance in breast cancer molecular classification and TNBC diagnosis through UCL/MRI/PET tri-modality imaging in vivo.By using this probe,MDA-MB-231 was successfully differentiated between MCF-7 tumor models in vivo.Based on the tumor imaging and molecular classification results,the probe is also expected to be modified for drug delivery in the future,contributing to the treatment of TNBC.The combination of nanoparticles with biomimetic cell membranes has the potential for multiple clinical applications. | Hanyi Fang Mengting Li Qingyao Liu Yongkang Gai Lujie Yuan Sheng Wang Xiao Zhang Min Ye Yongxue Zhang Mingyuan Gao Yi Hou Xiaoli Lan | 2020 | Nano-Micro Letters2020，12，5： | 5 |
| 10 | All-solid-state BiVO4/ZnIn2S4 Z-scheme composite with efficient charge separations for improved visible light photocatalytic organics degradation显示文摘Constructing a Z-scheme is a significant approach to improve the separation of photogene rated carriers for effective organic pollutant degradation.Herein,a BiVO4/ZnIn2S4(BZ) Z-scheme composite was successfully synthesized,and applied to photodegrade methyl orange(MO) irradiated by a LED lamp.Anchoring the BiVO4 on the ZnIn2S4 nanoparticles promoted the separation of photogenerated electronholes and broadened the light response range.The detailed characterizations,including surface morphology,elements valence state,and photocurrent performance,demonstrated that the enhanced separation of photogenerated carriers was the pivotal reason for the enhanced photocatalysis reaction.Benefiting from the excellent photocatalytic characteristics,the 5% mass ratio of BZ composite presented the highest MO degradation rate of 0.00997 min^-1,which was 1.9 and 10.3 times greater than the virgin ZnIn2S4 and BiVO4,respectively.Furthermore,the BZ hybrid materials indicated a well photo-stability in the four recycling tests. | Deling Yuan Mengting Sun Shoufeng Tang Yating Zhang Zetao Wang Jinbang Qi Yandi Rao Qingrui Zhang | 2020 | Chinese Chemical Letters2020，31，2： | 5 |
| 11 | Gram-scale preparation of dialkylideneacetones through Ca(OH)_2-catalyzed Claisen-Schmidt condensation in dilute aqueous EtOH显示文摘A synthetic method of dialkylideneacetones has been developed. Compared with known protocols, the method employed catalytic Ca(OH)_2 as the cheap, mild base catalyst and dilute aqueous EtOH(20%, v/v)as the green and safe solvent. The procedure was easily operated: In most cases, the product could be isolated by a simple filtration, and purified by washing with water. This paper provided experimental details of the reactions, which could be applied in gram-scale synthesis and should be a very reliable and practical protocol to prepare these useful compounds in laboratory and at the industrial level. | Hao Zhang Mengting Han Chenggen Yang Lei Yu Qing Xu | 2019 | Chinese Chemical Letters2019，30，1： | 4 |
| 12 | Evaluation of the four potential Cretaceous-Paleogene (K-Pg) boundaries in the Nanxiong Basin based on evidences from volcanic activity and paleoclimatic evolution显示文摘Determining the location of the Cretaceous-Paleogene(K-Pg) boundary in terrestrial strata is highly significant for studying the evolution of terrestrial ecosystems at the end of the Cretaceous(especially the extinction of non-avian dinosaurs). At present, research on terrestrial K-Pg boundaries worldwide is concentrated in the middle and high latitudes, such as North America and Northeast China. Although many studies have also been carried out in the Nanxiong Basin, located at low latitudes(which has become the standard for dividing and comparing the continental K-Pg stratigraphy in China), many researchers have proposed four possible boundaries from different perspectives. Therefore, the exact location remains to be determined. In this study, the total mercury(Hg) content, environmental magnetism, geochemistry, and other parameters for the samples collected near the four boundaries were determined and compared with existing records. Results indicated that: 1) The total Hg content significantly increased in the upper part of the Zhenshui Formation and Pingling part of the Shanghu Formation with sharp fluctuations. As per latest dating results of Deccan Traps, the significantly high Hg value was attributed to the Deccan Traps eruption. Boundary 1 was located in the middle of the Hg anomaly interval, which was consistent with the relationship between the global K-Pg boundary and time of volcanic eruption. 2) The reconstructed paleoclimate evolution curve revealed that the red sediments in the basin recorded the late Maastrichtian warming event(66.2 Ma). Regarding the relationship between the four boundaries and this warming event, only boundary 1 was found to be closest to the real K-Pg boundary of the Nanxiong Basin. | Mengting ZHAO Mingming MA Mei HE Yudan QIU Xiuming LIU | 2021 | Science China Earth Sciences2021，64，4： | 4 |
| 13 | An integrated multi-energy flow calculation method for electricity-gas-thermal integrated energy systems显示文摘The modeling and multi-energy flow calculation of an integrated energy system (IES) are the bases of its operation and planning. This paper establishes the models of various energy sub-systems and the coupling equipment for an electricity-gas-thermal IES, and an integrated multi-energy flow calculation model of the IES is constructed. A simplified calculation method for the compressor model in a natural gas network, one which is not included in a loop and works in constant compression ratio mode, is also proposed based on the concept of model reduction. In addition, a numerical conversion method for dealing with the conflict between nominal value and per unit value in the multi-energy flow calculation of IES is described. A case study is given to verify the correctness and speed of the proposed method, and the electricity-gas-thermal coupling interaction characteristics among sub-systems are studied. | Mengting Zhu Chengsi Xu Shufeng Dong Kunjie Tang Chenghong Gu | 2021 | Protection and Control of Modern Power Systems2021，6，1： | 4 |
| 14 | Recent Advancements on Photothermal Conversion and Antibacterial Applications over MXenes-Based Materials显示文摘The pernicious bacterial proliferation and emergence of super-resistant bacteria have already posed a great threat to public health,which drives researchers to develop antibiotic-free strategies to eradicate these fierce microbes.Although enormous achievements have already been achieved,it remains an arduous challenge to realize efficient sterilization to cut off the drug resistance generation.Recently,photothermal therapy(PTT)has emerged as a promising solution to efficiently damage the integrity of pathogenic bacteria based on hyperthermia beyond their tolerance.Until now,numerous photothermal agents have been studied for antimicrobial PTT.Among them,MXenes(a type of two-dimensional transition metal carbides or nitrides)are extensively investigated as one of the most promising candidates due to their high aspect ratio,atomic-thin thickness,excellent photothermal performance,low cytotoxicity,and ultrahigh dispersibility in aqueous systems.Besides,the enormous application scenarios using their antibacterial properties can be tailored via elaborated designs of MXenes-based materials.In this review,the synthetic approaches and textural properties of MXenes have been systematically presented first,and then the photothermal properties and sterilization mechanisms using MXenes-based materials are documented.Subsequently,recent progress in diverse fields making use of the photothermal and antibacterial performances of MXenes-based materials are well summarized to reveal the potential applications of these materials for various purposes,including in vitro and in vivo sterilization,solar water evaporation and purification,and flexible antibacterial fabrics.Last but not least,the current challenges and future perspectives are discussed to provide theoretical guidance for the fabrication of efficient antimicrobial systems using MXenes. | Shuyan Hao Hecheng Han Zhengyi Yang Mengting Chen Yanyan Jiang Guixia Lu Lun Dong Hongling Wen Hui Li Jiurong Liu Lili Wu Zhou Wang Fenglong Wang | 2022 | Nano-Micro Letters2022，14，11： | 4 |
| 15 | Cold Stress-induced Glucosyltransferase CsUGT78A15 is Involved in the Formation of Eugenol Glucoside in Camellia sinensis显示文摘Eugenol is a natural phenolic compound known for its health-promoting properties and its ability to add a floral scent to tea plants.Plant eugenol glycosides have been identified and shown to make important contributions to fruit floral quality.However,the details of their biosynthesis and metabolism in tea plants are still unknown.Here,eugenol glucoside was unambiguously identified as a native metabolite in the tea plant,and its biosynthesis was shown to be induced by low temperature treatment.Through the analysis of UGTs induced by low temperature,the glycosyltransferase CsUGT78A15 was identified in tea,and its encoded protein was shown to catalyze the glucosylation of eugenol.Vmax/Km ratios showed that eugenol was the most suitable substrate for CsUGT78A15.Sugar donor preference analysis showed that CsUGT78A15 had a higher selectivity for glucose,followed by galactose and glucuronic acid.The expression of CsUGT78A15was correlatedwith the accumulation of eugenol glucoside in different tissues and genotypes of tea.Down-regulation of CsUGT78A15 led to a decreased eugenol glucoside content under cold stress,indicating that CsUGT78A15 plays an important role in the biosynthesis of eugenol glucoside under cold stress.The identification of eugenol glucoside in the tea plant and the discovery of a cold stress-induced eugenol glucosyltransferase in tea provide the foundation for the improvement of tea flavor under cold stress and the biotechnological production of eugenol glucoside. | Mingyue Zhao Binbin Cai Jieyang Jin Na Zhang Tingting Jing Jingming Wang Yuting Pan Zixiang Zhou Yifan Zhao Yingying Feng Feng Yu Mengting Zhang Yating Li Zhonghua Liu Chuankui Song | 2020 | Horticultural Plant Journal2020，6，6： | 4 |
| 16 | A review on cyber security named entity recognition显示文摘With the rapid development of Internet technology and the advent of the era of big data,more and more cyber security texts are provided on the Internet.These texts include not only security concepts,incidents,tools,guidelines,and policies,but also risk management approaches,best practices,assurances,technologies,and more.Through the integration of large-scale,heterogeneous,unstructured cyber security information,the identification and classification of cyber security entities can help handle cyber security issues.Due to the complexity and diversity of texts in the cyber security domain,it is difficult to identify security entities in the cyber security domain using the traditional named entity recognition(NER)methods.This paper describes various approaches and techniques for NER in this domain,including the rule-based approach,dictionary-based approach,and machine learning based approach,and discusses the problems faced by NER research in this domain,such as conjunction and disjunction,non-standardized naming convention,abbreviation,and massive nesting.Three future directions of NER in cyber security are proposed:(1)application of unsupervised or semi-supervised technology;(2)development of a more comprehensive cyber security ontology;(3)development of a more comprehensive deep learning model. | Chen GAO Xuan ZHANG Mengting HAN Hui LIU | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，9： | 3 |
| 17 | Zephyranthes-like Co2NiSe4 arrays grown on 3D porous carbon frame-work as electrodes for advanced supercapacitors and sodium-ion batteries显示文摘Developing suitable electrode materials for electrochemical energy storage devices by biomorph assisted design has become a fascinating topic due to the fantastic properties derived from bio-architectures.Herein,zephyranthes-like Co_(2)NiSe_(4)arrays grown on butterfly wings derived three-dimensional(3D)carbon framework(Z-Co_(2)NiSe_(4)/BWC)is fabricated via hydrothermal assembly and further conversion method.Benefiting from its unique structure and multi-components,the obtained Z-Co_(2)NiSe_(4)/BWC electrode for supercapacitor delivers an excellent specific capacitance of 2,280 F·g^(-1)at 1 A·g^(-1).Impressively,the constructed asymmetric supercapacitor using Co_(2)NiSe_(4)/BWC as positive electrode and activated butterfly wings carbon as negative electrode acquires a high energy density of 42.9 Wh·kg^(-1)at a power density of 800 W·kg^(-1)with robust stability of 94.6%capacitance retention at 10 A·g^(-1)after 5,000 cycles.Moreover,the Z-Co_(2)NiSe_(4)/BWC as anode for sodium-ion batteries exhibits a high specific capacity of 568 mAh·g^(-1)at 0.1 A·g^(-1)and high cycling stability(maintaining 80.1%of the second cycle after 100 cycles).The outstanding electrochemical performances are ascribed to that the synergistic effect of bimetallic selenides and N-doped carbon improves electrochemical activities and conductivity.One-dimensional(1D)nanoneedles grown on 3D porous framework increase the exposure of redox-active sites,endow adequate transmission channels of electrons/ions,and guarantee stability of the electrode during charge/discharge processes.This study will shed light on the avenue towards extending such nanohybrids to excellent energy storage applications. | Yanchun Xue Xingmei Guo Mengrong Wu Jiale Chen Mengting Duan Jing Shi Junhao Zhang Fu Cao Yuanjun Liu Qinghong Kong | 2021 | Nano Research2021，14，10： | 3 |
| 18 | Synthesis, characterization and tribological evaluation of novel1,4-diazabicyclo[2.2.2]octane based dicationic ionic liquids as efficient antiwear lubricant additives显示文摘Ionic liquids have developed and been applied in lubricant field since 2001. Nevertheless, it is little known about novel dicationic ionic liquids for tribology applications in the past several years. In this paper, a sequence of novel dicationic ionic liquids based on 1,4-diazabicyclo[2.2.2]octane cations(DABCO) and different anions have been designed and identified. The structures of ILs were confirmed by Fourier transform infrared(FTIR) spectra, multinuclear(~1H,^(13)C,^(11)B,^(31)P and ^(19)F) magnetic resonance and mass spectrometry. The effects of anion type on thermal properties, wettability, kinematic viscosity and tribological properties were studied. It is found that all of these dicationic ionic liquids as additives exhibit excellent anti-wear and friction-reducing properties in PEG synthetic base oil under boundary lubrication conditions for steel-to-steel contact, which offers great potential for the highly efficient lubricant additives. Simultaneously, novel 1,4-diazabicyclo[2.2.2]octane cation offers an exceptional chance for the research and development of dicationic ionic liquids in various applications. | ZHAO LiNa CAI Tao ZHANG YunXiao YE MengTing SHANG WangJi LIU Dan TONG DingYi LIU ShengGao | 2019 | Science China(Technological Sciences)2019，62，2： | 3 |
| 19 | Multimodal interaction design and application in augmented reality for chemical experiment显示文摘Background Augmented reality classrooms have become an interesting research topic in the field of education,but there are some limitations.Firstly,most researchers use cards to operate experiments,and a large number of cards cause difficulty and inconvenience for users.Secondly,most users conduct experiments only in the visual modal,and such single-modal interaction greatly reduces the users'real sense of interaction.In order to solve these problems,we propose the Multimodal Interaction Algorithm based on Augmented Reality(ARGEV),which is based on visual and tactile feedback in Augmented Reality.In addition,we design a Virtual and Real Fusion Interactive Tool Suite(VRFITS)with gesture recognition and intelligent equipment.Methods The ARGVE method fuses gesture,intelligent equipment,and virtual models.We use a gesture recognition model trained by a convolutional neural network to recognize the gestures in AR,and to trigger a vibration feedback after a recognizing a five finger grasp gesture.We establish a coordinate mapping relationship between real hands and the virtual model to achieve the fusion of gestures and the virtual model.Results The average accuracy rate of gesture recognition was 99.04%.We verify and apply VRFITS in the Augmented Reality Chemistry Lab(ARCL),and the overall operation load of ARCL is thus reduced by 29.42%,in comparison to traditional simulation virtual experiments.Conclusions We achieve real-time fusion of the gesture,virtual model,and intelligent equipment in ARCL.Compared with the NOBOOK virtual simulation experiment,ARCL improves the users'real sense of operation and interaction efficiency. | Mengting XIAO Zhiquan FENG Xiaohui YANG Tao XU Qingbei GUO | 2020 | Virtual Reality & Intelligent Hardware2020，2，4： | 3 |
