Investigation of Power Density Amplification in Stacked Triboelectric Nanogenerators

Energy & Environmental Materials 2024年第5期7卷 372-379页

作者： Fan Shen qin Zhang Hengyu Guo Chen Cao ying Gong Junlei Wang yan Peng Zhongjie Li School of Mechatronic Engineering and Automation Shanghai University Department of Applied Physics Chongqing University Institute of Artificial Intelligence School of Future Technology Shanghai University School of Mechanical and Power Engineering Zhengzhou University Shanghai Artificial Intelligence Laboratory

In engineering practice, the output performance of contact separation TENGs(CS-TENGs) increases with the increase of tribo-pair area, which includes increasing the size of single layer CS-TENGs (SCS-TENGs) or the number of units (zigzag TENGs). However, such two strategies show significant differences in output power and power density. In this study, to seek a universal CS-TENG design solution, the output performance of a SCS-TENG and a zigzag TENG (Z-TENG) is systematically compared, including voltage,current, transferred charge, instantaneous power density, and charging power density. The relationship between contact area and output voltages is explored, and the output voltage equation is fitted. The experimental results reveal that SCS-TENGs yield better performance than Z-TENGs in terms of voltage, power, and power density under the same total contact area.

Jrokinase-type plasminogen activator： a new target for male contraception？

引用

Asian Journal of Andrology 2015年第2期17卷 269-273,I0009页

作者： ying qin yan Han Cheng-Liang Xiong Hong-Gang Li Lian Hu Ling Zhang Family Planning Research Institute Tongji Medical College Huazhong University of Science and Technology Wuhan China.

Urokinase-type plasminogen activator （uPA） is closely related to male reproduction. With the aim of investigating the possibility for uPA as a potential contraceptive target, in the present work, Kunming male mice were immunized by human uPA subcutaneous injection at three separate doses for 3 times. Then the potency of the anti-human uPA antibody in serum was analyzed, and mouse fertility was evaluated. Serum antibody titers for human uPA in immunized groups all reached 1：10,240 or higher levels by enzyme linked immunosorbent assay, and mating experiments revealed that pregnancy rates and the mean number of embryos implanted after mating declined obviously （P 〈 0.05） when compared with control groups. However, the mating capacity and reproductive organ weights had no obvious change, and histological analysis of the testes and epididymides also showed normal morphology for immunized male mice. Sperm function tests suggested that the sperm concentration, sperm viability, sperm motility, and in vitro fertilization rate for the cauda epididymis sperm in uPA-immunized groups were lower than those in the controls （P 〈 0.05）. Together, these observations indicated that subcutaneous injection human uPA to the male mice could effectively reduce their fertility, and uPA could become a new target for immunocontraception in male contraceptive development.
