| 1 | Effects of heat treatment on mechanical properties of an extruded Mg-4.3Gd-3.2Y-1.2Zn-0.5Zr alloy and establishment of its Hall–Petch relation显示文摘The effects of T4,T5,and T6 treatment on the microstructure and mechanical properties of the extruded Mg-4.3Gd-3.2Y-1.2Zn-0.5Zr(wt.%)alloy with a relatively low RE content(7.5 wt.%)were investigated.T4 treatment at 450–500°C induces a gradual grain growth ofα-Mg but an obvious transition of texture component from<0001>⊥ED to<0001>∥ED.Interdendritic LPSO phases are highly stable against annealing while intragranular ones experience dissolution and re-precipitation.After peak-ageing at 200°C,the elongation of as-extruded and T4 samples is just slightly reduced or even increased due to the weak ageing hardening response.T5 sample exhibits an attractive combination of strength and ductility,with a tensile yield strength(TYS)of 303 MPa and elongation of 20.0%.The Hall–Petch relation for the alloys with or without ageing treatment has been estimated.Grain boundary strengthening rather than precipitation strengthening has the dominant contribution to TYS,and a modified equation is developed to predict grain boundary strengthening values for Mg-Gd-Y-Zn-Zr alloys which contain different Schmid factors for basal slip. | Lei Liu Xiaojie Zhou Shilun Yu Jian Zhang Xianzheng Lu Xin Shu Zaijun Su | 2022 | Journal of Magnesium and Alloys2022，10，2： | 2 |
| 2 | Quasi-Three-Dimensional Cyclotriphosphazene-Based Covalent Organic Framework Nanosheet for Efficient Oxygen Reduction显示文摘Metal-free carbon-based materials are considered as promising oxygen reduction reaction(ORR)electrocatalysts for clean energy conversion,and their highly dense and exposed carbon active sites are crucial for efficient ORR.In this work,two unique quasi-three-dimensional cyclotriphosphazene-based covalent organic frameworks(Q3CTP-COFs)and their nanosheets were successfully synthesized and applied as ORR electrocatalysts.The abundant electrophilic structure in Q3CTP-COFs induces a high density of carbon active sites,and the unique bilayer stacking of[6+3]imine-linked backbone facilitates the exposure of active carbon sites and accelerates mass diffusion during ORR.In particular,bulk Q3CTP-COFs can be easily exfoliated into thin COF nanosheets(NSs)due to the weak interlayerπ-πinteractions.Q3CTP-COF NSs exhibit highly efficient ORR catalytic activity(half-wave potential of 0.72 V vs.RHE in alkaline electrolyte),which is one of the best COF-based ORR electrocatalysts reported so far.Furthermore,Q3CTP-COF NSs can serve as a promising cathode for Zn-air batteries(delivered power density of 156 mW cm-2 at 300 mA cm^(-2)).This judicious design and accurate synthesis of such COFs with highly dense and exposed active sites and their nanosheets will promote the development of metal-free carbon-based electrocatalysts. | Jianhong Chang Cuiyan Li Xiaoxia Wang Daohao Li Jie Zhang Xiaoming Yu Hui Li Xiangdong Yao Valentin Valtchev Shilun Qiu Qianrong Fang | 2023 | Nano-Micro Letters2023，15，9： | 1 |

| 10 | A Nitrogen, Sulfur co-Doped Porphyrin-based Covalent Organic Framework as an Efficient Catalyst for Oxygen Reduction显示文摘Oxygen reduction reaction(ORR) is a significant reaction for energy conversion systems(such as fuel cells, metal-air batteries, etc.). It is an urgent need to develop cheap, durable and highly-active catalysts for efficient ORR. Hence, we report a metal-free nitrogen and sulfur co-doped porphyrin-based covalent organic framework(COF) as a high-efficiency ORR catalyst[the onset potential(Eo) is 0.79 V and the half-wave potential(E1/2) is 0.70 V]. The double doping of N and S atoms causes uneven charge distribution around carbon atoms, which can act as catalytic active centers, improving ORR activity. Compared with single-atom doping, double atoms doping exhibits a higher activity due to the synergistic effect between different elements. These results demonstrate that reasonable design of stable metal-free COFs with a high electrochemical activity can promote their wide applications. | YU Xiaoming MA Yunchao LI Cuiyan GUAN Xinyu FANG Qianrong QIU Shilun | 2022 | Chemical Research in Chinese Universities2022，38，1： | 0 |

| 12 | Microfluidics embedded with microelectrodes for electrostimulation of neural stem cells proliferation显示文摘The regeneration of the injured nerve and recovery of its function have brought attention in the medical field. Electrical stimulation(ES) can enhance the cellular biological behavior and has been widely studied in the treatment of neurological diseases. Microfluidic technology can provide a cell culture platform with the well-controlled environment. Here a novel microfluidic/microelectrode composite microdevice was developed by embedding the microelectrodes to the microfluidic platform, in which microfluidics provided a controlled cell culture platform, and ES promoted the NSCs proliferation. We performed ES on rat neural stem cells(NSCs) to observe the effect on their growth, differentiation, proliferation, and preliminary explored the ES influence on cells in vitro. The results of immunofluorescence showed that ES had no significant effect on the NSCs specific expression, and the NSCs specific expression reached 98.9%± 0.4% after three days of ES. In addition, ES significantly promoted cell growth and the cell proliferation rate reached 49.41%. To conclude, the microfluidic/microelectrode composite microdevice can play a positive role in the nerve injury repair and fundamental research of neurological diseases. | Qian Li Bodong Kang Libin Wang Tao Chen Yu Zhao Shilun Feng Rongjing Li Hongtian Zhang | 2022 | Chinese Chemical Letters2022，33，3： | 0 |
| 13 | 用于放射性束物理实验的探测硅阵列的研制显示文摘With the development of radioactive beam facilities,several exciting results were provided concerning the understanding of fundamental nuclear physics.However,typical-beam intensities are always low and the production is often in very small quantities,so,new generation detectors need to be developed with large solid angle and angular coverage,which can identify particle effectively as well as possesses high energy resolution,high spatial resolution and high geometric efficiency.The new detector based on Double Side Silicon Strip Detector(DSSD)is foreseen for the study of the reaction production in the experiment of direct nuclear reaction above the Coulomb barrier using RIBLL[1,2]at the HIRFL[3,4].However,the disadvantage of the RIBs is that it has a broad distribution in coordinate spaces.Therefore,new detector system with high resolution and a large solid angle was developed successfully for performing nuclear reaction experiments using RIBs.The geometric efficiency of the new detector array with 5 large area DSSD telescopes increases up to 70%. | Duan Fangfang Yang Yanyun Gao Zhihao Liu Xingquan Ma Peng Wang Jiansong Bai Zhen Ma Junbing Hu Qiang Jin Shilun Jin Shuya Yu Gongming | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
