| 1 | A review of third generation SiC fibers and SiC_f/SiC composites显示文摘Compared with the first and second generations SiC fibers, the third generation SiC fibers have obvious improvement in heat-resistance, oxidation-resistance and creep-resistance, which promote the development of SiCf/SiC composite materials. Therefore, the third generation SiC fibers have more advantages and broader prospects in engineering applications. In this paper, the fabrication and properties of the third generation SiC fibers are compared and discussed. The preparation processes of the third generation SiC fibers reinforced SiC matrix composites and their application in aeroengine and nuclear energy fields are summarized, while their future development is prospected as well. | Pengren Wang Fengqi Liu Hao Wang Hao Li Yanzi Gou | 2019 | Journal of Materials Science & Technology2019，35，12： | 24 |

| 4 | Late Mesozoic rifting and its deep dynamic mechanisms in the central Sulu orogenic belt: Records from Lingshan Island显示文摘The Lingshan Island scientific drill confirms that two episodes(Laiyang period and Qingshan period) of rifting developed in the central Sulu orogenic belt(SOB) in Late Mesozoic. With a set of methods including fieldwork, drilling, core logging, zircon U-Pb dating and whole rock geochemistry applied, the age, the depositional sequence and the deep dynamic mechanisms of rift evolution were unraveled. The stratigraphic sequence of the Laiyang-Qingshan Groups on Lingshan Island was composed of two different rifting sequences:(1) Laiyang Group(147–125 Ma), which consists of deep-water gravity flow deposits with interlayers of intermediate volcanic rocks;and(2) Lower Qingshan Group(125–119 Ma), which unconformably overlies the former sequence and contains subaerial volcanic deposits and terrestrial deposits. The tectonic environment changed during the evolution of these two episodes of rifting: the rift was in a NNW-SSE extensional environment in the Laiyang period and showed the typical passive rifting character that “lithospheric extension and rifting preceded volcanism”. The passive rifting period was ended by a short WNW-ESE compression at about 125 Ma. After that, the tectonic environment transferred to a strong NW-SE extensional environment and the rifting evolved into a volcanic arc basin in the Qingshan period. The igneous rocks are shoshonitic to high-K calc-alkaline trachyandesites to trachytes with a few intercalated lamprophyres and a rhyolite.The geochemical characteristics of the igneous rocks indicate that they are mantle-derived melts with a metasomatized mantle source and/or crustal contamination. In addition, an increased thinning of the lithosphere happened during the rifting episodes.The low-angle subduction of the Paleo-Pacific plate in the Jurassic weakened the thickened SOB lithospheric mantle. The rollback of the subducting plate started in late Jurassic to early Cretaceous, and the SOB lithospheric mantle was delaminated synchronously because of the gravity collapse. Thus, this caused passive rifting in the Laiyang period. Thereafter, the rollback and trench retreat of the high-angle subducting Paleo-Pacific plate would have achieved its climax, resulting in the strong regional extension. Passive rifting was ended by the crustal uplift caused by asthenospheric upwelling beneath the rift. The lower crust was heated by the upwelling asthenosphere and partially melted to form felsic melts, which were emplaced upwards and erupted explosively. The rift evolved into a volcanic arc basin in the Qingshan period and showed some characteristics of active rifting. Above all, a passive rifting in the Laiyang period and a volcanic arc basin in the Qingshan period developed successively in the Lingshan Island area(the central SOB). This records the transfer of the study area from the Paleo-Tethys tectonic domain to the circum-Pacific tectonic domain. The delamination of SOB lithospheric mantle and the upwelling of asthenospheric material were the deep dynamic mechanisms driving the development and evolution of two rift episodes. Additionally, the rift development was controlled remotely by the subduction of the Paleo-Pacific plate. | Tengfei ZHOU Yaoqi ZHOU Nina SФAGER Paul Martin HOLM Zhenkai ZHANG Jun WANG Zhao LIANG Hongyu MU Yanjun CHENG Feifei LIU Miao WANG Yue ZHANG Hui ZHANG Yangjian GU Shihui DONG Hanjie ZHAO Manjie LI Yang CHEN Yanzi LIU | 2022 | Science China Earth Sciences2022，65，9： | 3 |

| 7 | Donor-Acceptor Typed AIE Luminogens with Near-infrared Emission for Super-resolution Imaging显示文摘Aggregation-induced emission(AIE)luminogens(AIEgens)with high brightness in aggregates exhibit great potentials in biological imaging,but these AIEgens are seldom applied in super-resolution biological imaging,especially in the imaging by using the structural illumination microscope(SIM).Based on this consideration,we synthesized the donor-acceptor typed AIEgen of DTPA-BTN,which not only owns high brightness in the near-infrared(NIR)emission region from 600 nm to 1000 nm(photoluminescence quantum yield,PLQYs=11.35%),but also displays excellent photo-stability.In addition,AIE nanoparticles based on 4,7-ditriphenylamine-[1,2,5]-thiadiazolo[3,4-c]pyridine(DTPA-BTN)were also prepared with highly emissive features and excellent biocompatibility.Finally,the developed DTPA-BTN-based AIE nanoparticles were applied in the super-resolution cellular imaging via SIM,where much smaller full width at half-maximum values and high signal to noise ratios were obtained,indicating the superior imaging resolution.The results here imply that highly emissive AIEgens or AIE nanoparticles can be promising imaging agents for super-resolution imaging via SIM. | SHEN Qifei XU Ruohan WANG Zhi ZHAO Tianyu ZHOU Yu XU Yanzi YANG Zhiwei LEI Ming MENG Lingjie DANG Dongfeng | 2021 | Chemical Research in Chinese Universities2021，37，1： | 0 |
| 8 | Preparation of MnO2 Loaded Hydrothermal Carbon-coated Electrospun PAN Fiber Membranes for Highly Efficient Adsorption and Separation of Cationic Dye显示文摘Hydrothermal carbonaceous materials and MnO2 have been proved to be promising adsorbents to remove organic dyes from wastewater.In this study,flexible MnO2 loaded hydrothermal carbon-coated electrospun poly-acrylonitrile(AC/MnO/PAN)fiber membranes were fabricated by a facile one-step hydrothermal method and activated by NaOH solution.The composite fibers exhibited large adsorption capacity toward cationic dyes and ex-cellent mechanical properties.The adsorption performance can be ftted well with pseudo-second order model and Langmuir isotherm model.The maximum adsorption for methylene blue(MB),methyI violet(MV)and malachite green(MG)are 1173.27,1106.31 and 1129.89 mg/g,respectively,according to Langmuir ftting.The AC/MnO/PAN fiber membrane also showed satisfactory performances for selective adsorption and recyclability.In addition,based on selective adsorption,the AC/MnOz/PAN fiber membranes that are repulsive to the anionic dye methyl orange(MO)can separate the MB/MO mixture solution by dynamic filration.Thus,this work not only provides a facile strategy to fabricate large capacity adsorbents,but also dermonstrates the potential appications in the dye wastewater treatment field. | WANG Yuannan LI Wenyan CHAO Shen LI Yanzi LI Xiang HE Dayong WANG Ce | 2020 | Chemical Research in Chinese Universities2020，36，6： | 0 |
| 9 | Research on Dance Evaluation Technology Based on Human Posture Recognition显示文摘In view of the increase in the number of people participating in dance rating assessments,this paper proposes a dance assessment technology based on human body posture recognition.This technique adopts the human target detection of the dance video,extracts bone key points,and then uses the video data set col-lected by professional dancers to conduct PoseC3D model training,enabling the model to classify the basic movements of the dance;then,the dynamic time nor-malization algorithm is used to evaluate the classified movements.The experimen-tal results show that this technology can accurately identify the basic movements of various dances and accurately give the evaluation score of the corresponding movements,thus reducing the work intensity of the assessment staff. | Yanzi Li Yiwen Zhu Yanqing Wang Yiming Gao | 2023 | 国际计算机前沿大会会议论文集2023，，1： | 0 |
| 10 | The Formation of SO_(2) and Emission Reduction Solutions in the Preparation of a Hydrogenation Catalyst Support显示文摘The key reason for SO_(2) formation during the production of a residue hydrogenation catalyst support was identified and subsequent emission reduction solutions were then investigated and verified systematically.The results demonstrated that carbon-containing organic materials,including sesbania powder and cellulose,did not completely decompose over the temperature range of 350−600℃during the heating stage of the calcination process,but rather underwent a condensation reaction within the same temperature range to form carbon-containing species with a lower ratio of hydrogen to carbon and a higher condensation degree,which promoted the decomposition of sulfate to form SO_(2).Systematic experimental work revealed that three different measures,i.e.,applying the staged calcination method,reducing the heating rate,and increasing the air flow rate,during the calcination process could all achieve the effect of reducing SO_(2) emissions. | Hu Anpeng Wang Zhen Yang Qinghe Hu Dawei Gong Yu Jia Yanzi Dai Qiaoling Pu Ning | 2024 | China Petroleum Processing & Petrochemical Technology2024，26，1： | 0 |
| 11 | Synthesis of D-A typed AIE luminogens in isomeric architecture and their application in latent fingerprints imaging显示文摘Among the emitters in powder dusting to visualize the latent fingerprints(LFPs),aggregation-induced emission luminogens(AIEgens)are well employed for their high brightness and resistance to photobleaching.However,the serious background interference and low resolution still limit their fast development.Therefore,to further enhance the signal-to-noise ratio in LFPs imaging,especially to improve the analysis for level 3 details,donor-acceptor(D-A)typed AIEgens of DTPA-2,3-P,DTPA-2,5-P and DTPA-2,6-P are designed here.It is observed that strong emission covering from 450nm to 650nm can be obtained for all these molecules,especially that a high PLQY value of 10.06%in solids is achieved in DTPA-2,3-P.This is much higher than that of the other two cases(0.80%and 0.51%).By utilizing the DTPA-2,3-P in powder dusting,fluorescence imaging of LFPs can be clearly captured on both smooth and rough substrates.Moreover,confocal laser scanning microscope(CLSM)enables us to achieve high-resolution LFPs imaging in both 2D and 3D views,providing more detailed information of fingerprints pores in width,distance,distribution,and shapes.The results here demonstrate that highly emissive AIEgen of DTPA-2,3-P could be an excellent candidate for the visualization of fingerprints,thus providing the potential application in criminal investigation in the future. | Peijuan Zhang Qifei Shen Yu Zhou Fengyi He Bo Zhao Zhi Wang Ruohan Xu Yanzi Xu Zhiwei Yang Lingjie Meng Dongfeng Dang | 2023 | Chinese Chemical Letters2023，34，8： | 0 |
| 12 | How aging affects bone health via the intestinal micro-environment显示文摘Increasing life expectancy and an aging population lead to age-related bone diseases like osteoporosis and low bone mass more prevalent.These conditions represent a common,costly and chronic burden,not only for elderly but also to society at large.Consequently,elucidating the pathophysiology and developing effective therapies for these diseases is of paramount importance.Recent advances in research have identified the gut as a novel and promising target for addressing bone disorders,giving rise to the concept of the“gut-bone axis”.An in-depth review of the latest insights into the effects of age-related physiological changes in the gastrointestinal tract on bone health is presented in this article.It examines how the“gut-bone”axis interacts with bone aging across various domains,including metabolism,nutrition,intestinal permeability,immunity,and oxidative stress. | HUAN HU YUE HUANG FANGZHOU LIU QIAN WANG YANZI YAO | 2024 | BIOCELL2024，48，3： | 0 |
| 13 | Automatic Generation of Graduation Thesis Comments Based on Multilevel Analysis显示文摘In the evaluation of graduation theses,teachers’evaluation criteria for graduation theses are inconsistent,subjective and not completely reasonable and fair.This paper proposes using the BERT model to analyze the existing graduation papers in colleges and universities and make quantitatively evaluate students’graduation projects according to the given relevant parameters.The purpose of this method is to use standards to make comprehensive,systematic and accurate evaluations and avoid the phenomenon of high repetition and similarity caused by a large number of teachers’comments.This can not only effectively improve the efficiency of graduation design evaluation but also improve the fairness of evaluation.In this paper,changing the review work of the graduation thesis from pure manual operation to machine review combined with manual operation can not only reduce manpower consumption but also make the review work more objective and fair,making it more objective on the basis of traditional subjective review. | Yiwen Zhu Zhaoyi Li Yanzi Li Yanqing Wang | 2022 | 国际计算机前沿大会会议论文集2022，，1： | 0 |
| 14 | A Novel Hollow Carbon@MnO_(2) Electrospun Nanofiber Adsorbent for Efficient Removal of Pb^(2+) in Wastewater显示文摘Lead ion(Pb^(2+))is one of the most hazardous heavy metal ions in aquatic environments.Carbon materials and manganese dioxide(MnO_(2))have been shown to be prospective adsorbents to cope with the lead pollution.In this study,a novel hollow carbon@MnO_(2) composite nanofiber adsorbent was prepared by the combination of electrospinning and carbonization.The PAN nanofiber membrane is subjected to a pre-oxidation and carbonization process,and then the obtained carbon nanofibers react with KMnO4 solution during the hydrothermal process to develop the hollow carbon@MnO_(2) nanofibers.The hollow carbon@MnO_(2) nanofibers displayed a higher adsorption capacity of Pb^(2+)than carbon and MnO_(2)/PDA/PAN nanofibers.The maximum adsorption capacity toward Pb^(2+)by hollow carbon@MnO_(2) nanofibers was 460.83 mg/g.After 5 adsorption-desorption cycles,the carbon@MnO_(2) nanofibers had a good recyclability and the removal efficiency remained 81.47%.Moreover,the removal efficiency of the hollow composite nanofibers for Pb^(2+)from real wastewater could reach 94.37%.This work shows a strategy for synthetics of the hollow carbon@MnO_(2) nanofibers,which exhibits a promising potential in actual wastewater treatment. | LI Wenyan LI Yanzi LIU Jiadi CHAO Shen YANG Tianyi LI Lijuan WANG Ce LI Xiang | 2021 | Chemical Research in Chinese Universities2021，37，3： | 0 |
