| 1 | Rapid repair techniques for severely earthquake-damaged circular bridge piers with flexural failure mode显示文摘In this study, three rapid repair techniques are proposed to retrofit circular bridge piers that are severely damaged by the flexural failure mode in major earthquakes. The quasi-static tests on three 1:2.5 scaled circular pier specimens are conducted to evaluate the efficiency of the proposed repair techniques. For the purpose of rapid repair, the repair procedure for all the specimens is conducted within four days, and the behavior of the repaired specimens is evaluated and compared with the original ones. A finite element model is developed to predict the cyclic behavior of the repaired specimens and the numerical results are compared with the test data. It is found that all the repaired specimens exhibit similar or larger lateral strength and deformation capacity than the original ones. The initial lateral stiffness of all the repaired specimens is lower than that of the original ones, while they show a higher lateral stiffness at the later stage of the test. No noticeable difference is observed for the energy dissipation capacity between the original and repaired pier specimens. It is suggested that the repair technique using the early-strength concrete jacket confined by carbon fiber reinforced polymer(CFRP) sheets can be an optimal method for the rapid repair of severely earthquake-damaged circular bridge piers with flexural failure mode. | Sun Zhiguo Li Hongnan Bi Kaiming Si Bingjun Wang Dongsheng | 2017 | Earthquake Engineering and Engineering Vibration2017，16，2： | 8 |
| 2 | Effects of Continuous Cropping of Panax notoginseng on the Properties of Rhizosphere Soil显示文摘[Objective] This experiment aimed to investigate the effects of continuous cropping of Panax notoginseng on the properties of rhizosphere soil. [Method] A total of 12 rhizospheres oil samples were collected in the fields continuously cropped with P. notoginseng for different years and the soil properties including pH value, contents of available N, available K, available P,total N, total K, total P and organic matter were determined. [Result] With the increase in the number of years of continuous cropping, seven soli indices: soil pH value, organic matter content, total N, total P, total K, available P and available K gradually increased, while available N showed a gradual downward trend. The contents of organic matter content, total N, total P, total K,available P, available K and available N after three years of continuous cropping were increased by 74.93%, 65.85%, 123.82%,18.78%, 341.67%, 120.16% and-32.16%, respectively, indicating that continuous cropping of P. notoginseng resulted in nutrient enrichment in rhizosphere soils. The pH value and available N in IBC(soil inside the border check) and UBC(soil under the border check) were higher than that in BBC(soil beside the border check), suggesting that the soil was gradually alkalized due to the continuous cropping of P. notoginseng. [Conclusion] These results suggest that pH change and nutrient imbalance may be the obstacles to the continuous cropping of P. notoginseng. | Kaiming LI Meixiang LIU Qianhui SUN Zilong ZHANG | 2017 | Agricultural Science & Technology2017，18，4： | 4 |
| 3 | Trending IC design directions in 2022显示文摘For the non-stop demands for a better and smarter society, the number of electronic devices keeps increasing exponentially;and the computation power, communication data rate, smart sensing capability and intelligence are always not enough. Hardware supports software, while the integrated circuit(IC) is the core of hardware. In this long review paper, we summarize and discuss recent trending IC design directions and challenges, and try to give the readers big/cool pictures on each selected small/hot topics. We divide the trends into the following six categories, namely, 1) machine learning and artificial intelligence(AI) chips, 2) communication ICs, 3) data converters, 4) power converters, 5) imagers and range sensors, 6) emerging directions. Hope you find this paper useful for your future research and works. | Chi-Hang Chan Lin Cheng Wei Deng Peng Feng Li Geng Mo Huang Haikun Jia Lu Jie Ka-Meng Lei Xihao Liu Xun Liu Yongpan Liu Yan Lu Kaiming Nie Dongfang Pan Nan Qi Sai-Weng Sin Nan Sun Wenyu Sun Jiangtao Xu Jinshan Yue Milin Zhang Zhao Zhang | 2022 | Journal of Semiconductors2022，43，7： | 3 |
| 4 | Ti3C2Tx/PEDOT:PSS hybrid materials for room-temperature methanol sensor显示文摘It is essential to develop a methanol gas sensor with high selectivity and low working temperature for human health and environmental monitoring.In this work,a blend of PEDOT:PSS and Ti3C2Tx with the mass ratio of 4:1 is used to fabricate a methanol gas sensor.It possesses a high response ratio of the largest response and the second largest response(5.54)and an enhanced response compared to pure PEDOT:PSS and pure Ti3C2Tx tested at room temperature.These findings may pave the way towards design of the MXenes based high-performance gas-sensing materials in the future. | Xiaofeng Wang Kaiming Sun Ke Li Xu Li Yury Gogotsi | 2020 | Chinese Chemical Letters2020，31，4： | 3 |
