| 1 | Tuning the Molecular Weight of Chlorine-Substituted Polymer Donors for Small Energy Loss显示文摘The molecular weight of polymers plays a major role in their aggregation and miscibility in active layer,which eventually dominate the energy loss and device performance.A series of chlorine-substituted PBD-CI polymers with controlled molecular weight have been synthesized as templates to discern a relationship between molecular weight and the optical properties,energy levels,morphologies,energy loss and photovoltaic performance.Although it has similar optical and electrochemical properties,when blended with acceptor N3,the low molecular weight polymer PBD-CI_(L) gives the biggest energy loss value,and a PCE of 12.06%.PBD-CI_(H) shows a moderate energy loss,but displays the lowest PCE of 9.00%as a result of excessive aggregation.PBD-CI_(M) with a medium molecular weight gives the smallest energy loss and achieves a PCE of 17.17%,which is among one of the highest values recorded to date for the C卜substituted polymer solar cells.Moreover,the molecular weight mainly affects the nonradiative energy loss(△E_(3)), PBD-CI_(M) also shows the smallest value of 0.252 eV among three polymer donors.These results show the effect of controlling the molecular weight to achieve a small energy loss and provide guidelines which can lead to an understanding of the real photovoltaic performance of new materials. | Tingxing Zhao Huan Wang Mingrui Pu Hanjian Lai Hui Chen Yulin Zhu Nan Zheng Feng He | 2021 | Chinese Journal of Chemistry2021，39，6： | 0 |
| 2 | Expression and Activity Analysis of Non-Structural Protein 2 (NS2) of Bombyx mori Densovirus Zhenjiang Strain显示文摘The gene of the non-structure protein 2 (NS2) was cloned by PCR from the genome of Bombyx mori densovirus Zhenjiang strain (BmDNV-Z), inserted into prokaryotic expression vector pET28a to construct recombinant plasmid pET28a-NS2 and then expressed in bacteria Escherichia coli BL21 (DE3). The expressed recombinant protein was identified by SDS-PAGE and Western blot analysis. Then, the recombinant protein was purified by Ni-NTA column, renatured and tested for enzyme activities. The purified NS2 protein exhibited a helicase activity unwinding double-stranded DNA substrates into single-strand primers, and higher unwinding activity to polarity substrate. Similarly, the purified NS2 protein possessed an ATPase activity and its enzyme activity was 0.276 μmol μg-1 h-1 in this study. The results indicated that the non- structure protein which encoded by the gene of BmDNV-Z NS2 possesses the biological activities of helicase and ATPase, and the helicase prefers to polarity substrates. Based on these results, it is speculated that the gene of BmDNV-Z NS2 plays an important role in the viral DNA replication. | ZHAO Pan TANG Shun-ming LIU Tingx LIU Ting QIN Guang-xing GUO Xi-j ie | 2010 | Agricultural Sciences in China2010，9，12： | 0 |
