1A 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 2019Journal of Materials Science & Technology2019,35,12:24

4A New Kinetic Model for Residue Hydrotreating Based on Chemical Reaction Sections显示文摘New definition of virtual molecular-group components about CH and CH2 is proposed in the paper.The new reaction,hydrogenation of CH to CH2(HDCH),can be used to represent the change of C and H in RHT.By using the lumping approach,the kinetic models about HDCH,HDS,HDN,HDCCR,HDM,HDNi and HDV reactions were established.They are key components of the new kinetic model for RHT based on reaction sections.During the construction of kinetic model,goodness-to-fit(R^2)between test data and model data was set as the target value,and the model parameters were calculated accurately.In verification test,the predicted content of H,S,N,CCR,M,Ni and V can match well with the test data.Zhang Kui Dai Lishun Nie Hong Shao Zhicai Liu Tao Deng Zhonghuo Han Wei Jia Yanzi 2020China Petroleum Processing & Petrochemical Technology2020,22,2:4
5Late 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 2022Science China Earth Sciences2022,65,9:3
6CD38 deficiency alleviates Ang II-induced vascular remodeling by inhibiting small extracellular vesicle-mediated vascular smooth muscle cell senescence in mice显示文摘CD38 is the main enzyme for nicotinamide adenine dinucleotide(NAD)degradation in mammalian cells.Decreased NAD levels are closely related to metabolic syndromes and aging-related diseases.Our study showed that CD38 deficiency significantly alleviated angiotensin II(Ang ll)-induced vascular remodeling in mice,as shown by decreased blood pressures;reduced vascular media thickness,media-to-lumen ratio,and collagen deposition;and restored elastin expression.However,our bone marrow transplantation assay showed that CD38 deficiency in lymphocytes led to lack of protection against Ang ll-induced vascular remodeling,suggesting that the effects of CD38 on Ang ll-induced vascular remodeling might rely primarily on vascular smooth muscle cells(VSMCs),not lymphocytes.In addition,we observed that CD38 deficiency or NAD supplementation remarkably mitigated Ang ll-induced vascular senescence by suppressing the biogenesis,secretion,and internalization of senescence-associated small extracellular vesicles(SA-sEVs),which facilitated the senescence of neighboring non-damaged VSMCs.Furthermore,we found that the protective effects of CD38 deficiency on VSMC senescence were related to restoration of lysosome dysfunction,particularly with respect to the maintenance of sirtuin-mediated mitochondrial homeostasis and activation of the mitochondria-lysosomal axis in VSMCs.In conclusion,our findings demonstrated that CD38 and its associated intracellular NAD decline are critical for Ang ll-induced VSMC senescence and vascular remodeling.Lu Gan Demin Liu Jing Liu Erya Chen Chan Chen Lian Liu Hang Hu Xiaohui Guan Wen Ma Yanzi Zhang Yarong He Bofu Liu Songling Tang Wei Jiang Jianxin Xue Hongbo Xin 2021Signal Transduction and Targeted Therapy2021,6,7:2

18Characteristics of Hydrotreating Reaction in VRDS Units Located along the Yangtze River and Overall Solution for Long-cycle Running显示文摘The VRDS feedstock processed in refineries along the Yangtze River has special characteristics, including high Fe and Ca content, and low sulfur and high nitrogen content. Depending upon feedstock properties and operating conditions,some approaches have been developed by the SINOPEC Research Institute of Petroleum Processing(RIPP), which include installing the decalcification facility, developing new guard catalysts and HDCCR catalysts, implementing a new catalyst grading approach, developing a highly efficient distribution technology and applying RICP process in some refineries.The application effects have revealed that the integrated technology, which can be conducive to the long-cycle operation developed by RIPP, can maximize the deposits uptake capacity of the guard reactor and the activity of grading catalysts.Shao Zhicai Jia Yanzi Dai Lishun Yang Qinghe Nie Hong 2017China Petroleum Processing & Petrochemical Technology2017,19,3:1
19Alumina Supported Vanadium Oxide Catalysts for Residue Hydrotreating显示文摘In order to evaluate the role of vanadium in the hydrogenation (HYD) reaction, a series of alumina supported vanadium catalysts were prepared and characterized by SEM, XRD, Raman spectrometry, 51V NMR, XPS, as well as TPR analyses. The catalytic performance of vanadium in HYD of model molecules (naphthalene) and real feedstock (Kuwait atmospheric residue) was studied after sulfidation of the catalysts. It can be concluded that the HYD capabilities of V/Al2O3 catalysts are lower than that of conventional NiMo/Al2O3 catalyst (RefNiMo). The V/Al2O3 catalysts can only facilitate hydrogenation of the first ring of naphthalene, but have little effect on the further hydrogenation of tetralin. Owing to the different forms of metals and sulfur compounds in residue, the weak HYD activity of V/Al2O3 catalysts is able to facilitate the HDM reaction of the residue, albeit with a slight effect on HDS activity.Jia Yanzi Li Dingjianyi Yang Qinghe Li Dadong Sun Shuling Nie Hong 2013China Petroleum Processing & Petrochemical Technology2013,15,1:1
