7Red light-driven generation of reactive oxygen species for the targeted oxidation of glioma cells and thiols over covalent organic framework显示文摘Reactive oxygen species(RoS)are essential for biological processes like cell signaling and chemical processes like organic oxidation.Moreover,the sufficient generation of RoS plays a significant role in targeted tumor treatments or oxidation of organics.Herein,a hydrazone-linked porphyrin covalent organic framework(Por-DETH-COF)is developed for red light-induced generation of ROS like singlet oxygen(^(1)O_(2))or superoxide(O_(2)·^(-))to undertake different but targeted oxidations.First,^(1)O_(2)is adopted in photodynamic therapy(PDT)for the oxidation of glioma cells.The PDT efficiency of Por-DETH-COF on the apoptosis of glioma cells is explored through flow cytometry and western blot assay.The apoptosis rate of glioma cells significantly increases over Por-DETH-COF under 660nm red light illumination,suggestive of the potency of^(1)O_(2).Second,O_(2)^(·-)is employed for the targeted oxidation of thiols.A series of thiols could be efficiently oxidized to corresponding disulfides over Por-DETH-COF under 660 nm red light illumination,indicative of the significance of O_(2)^(·-).This work highlights the potential of covalent organic frameworks in generating Ros for precise medical applications of complex chemical environments.Heng Wei Xia Li Fengwei Huang Shujuan Wu Huimin Ding Qianxue Chen Mingchang Li Xianjun Lang 2023Chinese Chemical Letters2023,34,12:0
8Evaluation of cable tension sensors of FAST reflector from the perspective of EMI显示文摘The active reflector of FAST(five-hundred-meter aperture spherical radio telescope) is supported by a ring beam and a cable-net structure,in which nodes are actively controlled to form series of real-time paraboloids.To ensure the security and stability of the supporting structure,tension must be monitored for some typical cables.Considering the stringent requirements in accuracy and longterm stability,magnetic flux sensor,vibrating wire strain gauge and fiber bragg grating strain gauge are screened for the cable tension monitoring of the supporting cable-net.Specifically,receivers of radio telescopes have strict restriction on electro magnetic interference(EMI) or radio frequency interference(RFI).These three types of sensors are evaluated from the view of EMI/RFI.Firstly,these fundamentals are theoretically analyzed.Secondly,typical sensor signals are collected in the time and analyzed in the frequency domain,which shows the characteristic in the frequency domain.Finally,typical sensors are tested in an anechoic chamber to get the EMI levels.Theoretical analysis shows that Fiber Bragg Grating strain gauge itself will not lead to EMI/RFI.According to GJB151 A,frequency domain analysis and test results show that for the vibrating wire strain gauge and magnetic flux sensor themselves,testable EMI/RFI levels are typically below the background noise of the anechoic chamber.FAST finally choses these three sensors as the monitoring sensors of its cable tension.The proposed study is also a reference to the monitoring equipment selection of other radio telescopes and large structures.朱明 Wang Qiming Dennis Egan Wu Mingchang Sun Xiao 2016High Technology Letters2016,22,2:0
9Compiling Textbook of Elastic-plastic Mechanics for Major of Oil and Gas Storage and Transportation Engineering显示文摘'Elastic-plastic mechanics'is a required course for engineering postgraduates in petroleum colleges and universities,such as students who major in oil and gas storage and transportation engineering.It is the basis for personnel engaged in structural safety assessment.In the past teaching process,the teaching effects of this course were unsatisfactory.There are many reasons for this phenomenon,such as the strong theoretical nature of this course,the need for a large number of formula derivation,the high requirements for students'mechanical foundation and mathematical foundation,the lack of appropriate teaching materials and the slackness of students'minds.Based on years of teaching experience,the teaching team has reformed the existing teaching materials of“Elastic-plastic mechanics”to meet the needs of petroleum colleges and universities.In this reform,we have referred to a large number of published textbooks of“Elasticplastic mechanics”and the experience of textbook construction at home and abroad.The newly compiled textbook of“Elastic-plastic mechanics”plays a certain role in improving the teaching quality of“Elastic-plastic mechanics”in petroleum colleges and universities.Yanfei Chen Yufeng Yan Heng Ni Mingchang He Zhihao Wang Zuming Wu 2021Journal of Educational Theory and Management2021,5,2:0
10Study and application of vibrating wire strain gauge in monitoring cable tension of FAST cable-net显示文摘A cable net structure is selected to support its reflecting triangular aluminum panels of FAST(five-hundred-meter aperture spherical radio telescope).To ensure the security and stability of the supporting structure,cable force of typical cables must be monitored on line.Considering the stringent requirements in installation,accuracy,long-term stability and EMI(Electromagnetic interference),most of the commonly used cable force measurement methods or sensors are not suitable for the cable force monitoring of the supporting cable-net of FAST.A method is presents to accomplish the cable force monitoring,which uses a vibrating wire strain gauge to monitor the strain of linear strain area at the anchor head.Experiments have been carried out to verify the feasibility.The method has a series of advantages,such as high reliability,high accuracy,good dynamic performance and durability,easiness of maintenance,technical maturity in industry and EMI shielding.Theoretical analysis shows that there is a linear relationship between the cable body force and anchor head surface strain,and experimental results proves a good linear relationship with excellent repeatability between the cable body force and anchor head surface strain measured by the vibrating wire strain gauge,with a linear fit better than 0.98.Mean square error in practical measuring is 2.5t.The relative error is better than 4%within the scope of the cable force in FAST operation which meets practical demand in FAST engineering.孙晓 Wang Qiming Zhu Ming Wu Mingchang 2015High Technology Letters2015,21,4:0
11TIME-DEPENDENT FATIGUE AND ITS MICROMECHANISM OF SUPERALLOY GH169 UNDER OXIDATION显示文摘The time-dependent fatigue and its micromechanism of superalloy GH169 at 650℃ have beenstudied.Under the same stress and duration,its cyclic life in Ar is shorter than that in air.Thedamage mechanism is mainly of the interaction between high temperature oxidation and fa-tigue.The fracture surface of GH169 specimen oxidized at 650℃ in air is revealed to be cov-ered with a dense and even oxide film,but in Ar,with uncontinuous oxide particles.As thetime prolonged,the Cr2O3 content in the surface oxides increases in air and decreases in Ar.HE Jinrui LU Younian WANG Qingsui SU Hansheng ZHANG Xueduo WU Mingchang ZHU Qiao Beijing Institute of Aeronautical Materials,Beijing,China P.O.No.81—23,Beijing 100095,China 1990Acta Metallurgica Sinica(English Letters)1990,3,5:0
