| 1 | Non-contact cylindrical rotating triboelectric nanogenerator for harvesting kinetic energy from hydraulics显示文摘Hydraulics provide a unique and widely existed mechanical energy source around us,such as in water or oil pipes,and sewers.Here,a non-contact cylindrical rotating triboelectric nanogenerator(TENG)was developed to harvest the mechanical energy from water flows.Operation of the TENG was based on the non-contact free-rotating between a curved Cu foil and a flexible nanostructured fluorinated ethylene propylene(FEP)polymer film.The free-standing distance between two rotating interfaces avoided abrading of electrode materials.The TENG was able to effectively convert mechanical energy of the water flow into electricity.When driven by water flow,the output voltage and current of the TENG reached 1,670 V and 13.4 uA,respectively.Without any energy storage component,the produced electricity could instantaneously power 12 white light emitting diodes(LEDs)bulbs and a digital timer.This non-contact rotating TENG would provide new opportunities for harvesting energy from many types of hydraulics as a self-sustainable power source for sensing,detection,and protection. | Nan Zhang Cheng Qin Tianxing Feng Jun Li Zhirui Yang Xiupeng Sun Erjun Liang Yanchao Mao Xudong Wang | 2020 | Nano Research2020，13，7： | 4 |
| 2 | mRNA expression of CYP4 in marine polychaete Marphysa sanguinea in response to benzo[a]pyrene显示文摘Rapid amplification of cDNA ends (RACE) and real-time polymerase chain reaction (RT-PCR) were carried out to analyze the CYP4 gene expression in polychaete Marphysa sanguinea exposed to benzo[a]pyrene (BaP) in this study. The full length of MsCYP4 cDNA was 2 470 bp, and it encoded 512 amino acids. The deduced amino acid sequence showed 47% identity with CYP4F from frog Xenopus tropicalis and shared high homology with other known CYP4 sequences. To analyse the role of CYP4 in protecting M. sanguinea from BaP exposure, three BaP groups were established: 0.5, 5 and 50 μg/L. Polychaetes were sampled after 3, 7 and 12 d. At 0.5 μg/L, the effect of BaP on MsCYP4 gene expression increased with time prolonged. MsCYP4 gene expression curve showed Ushaped trend with time in 5 and 50 μg/L BaP groups. Therefore, MsCYP4 gene may play an important role in maintaining the balance of cellular metabolism and protecting M. sanguinea from BaP toxicity. | Wanjuan Li Huan Zhao Fuyang Ba Shaojuan Li Xiupeng Sun Dazuo Yang Yibing Zhou | 2019 | Acta Oceanologica Sinica2019，38，6： | 0 |
