| 1 | Subcellular localization of the stripe disease-specific protein encoded by rice stripe virus (RSV) in its vector,the small brown planthopper,Laodel-phax striatellus显示文摘The stripe disease-specific protein (SP) encoded by the rice stripe virus (RSV) was successfully used as a localization signal of the virus in its vector, the small brown lanthopper, Laodelphax striatellus Fallen. Immunogold particles in large numbers were detected in various parts of the viruliferous females: the ovum, surface of chorion, the mid-gut lumen, and the columnar cells. Whereas there was noneof these particles in the non-viruliferous females and males, and testis of viruliferous males. Endosymbionts (mycetocytes) were abundant, harboring ovaries of both viruliferous and non-viruliferous females, but none in the testis of males. The results provided us with the direct proof that RSV is a ciruculative and propagative plant virus and it was transovarially transmitted alongside with endosymbionts of its vector. Therefore, we deem it a nice lead for future studies on the mechanism of RSV transmission and functioning of its viral proteins. | WU Aizhong ZHAO Yan QU Zhicai SHEN Daleng PAN Chongguang SU Deming | 2001 | Chinese Science Bulletin2001，46，21： | 23 |
| 2 | Tailoring WB morphology enables d-band centers to be highly active for high-performance lithium-sulfur battery显示文摘The d-band centers of catalysts have exhibited excellent performance in various reactions.Among them,the enhanced catalytic reaction is considered a crucial way to power dynamics and reduce the“shuttle”effect in polysulfide conversions of lithium-sulfur batteries.Here,we report two-dimensional-shaped tungsten borides(WB)nanosheets with d-band centers,where the d orbits of W atoms on the(001)facets show greatly promoting the electrocatalytic sulfur reduction reaction.As-prepared WB-based Li-S cells exhibit excellent electrochemical performance for Li-ion storage.Especially,it delivers superior capacities of 7.7 mAh/cm^(2) under the 8.0 mg/cm^(2) sulfur loading,which is far superior to most other electrode catalysts.This study provides insights into the d-band centers as a promising catalyst of twodimensional boride materials. | Yuwei Zhao Chang Liu Chenyang Zha Jing Li Chongguang Lyu Kaixi Wang Junfeng Li Kwan San Hui Linghai Zhang Kwun Nam Hui | 2023 | Chinese Chemical Letters2023，34，11： | 0 |
| 3 | Investigation on two triphenylene based electron transport materials显示文摘Promoting electron mobility is the key to designing high performance electron transport materials(ETMs). Formation of intermolecular interaction can be helpful to enhance their electron mobilities as a result of more ordered molecular stacking.Here, to reveal the inherent influence of intermolecular π-π stacking on the electron mobilities, we designed two ETMs, namely,2,4-diphenyl-6-[3-(2-triphenylenyl)phenyl]-1,3,5-triazine(TPTRZ) and 2,4-diphenyl-6-[4′-(2-triphenylenyl)[1,1′-biphenyl]-3-yl]-1,3,5-triazine(TPPTRZ). Thermal, photophysical and electrochemical measurement results indicate they are good ETM candidates. Additionally, TPTRZ and TPPTRZ exhibit high electron mobilities of 3.60×10^(-5) and 3.58×10^(-5) cm^2V-1 s^(-1), respectively, at an electric field of 7×10~5 V cm^(-1). By taking X-ray single crystal structure, theoretical calculation and time of flight(TOF) results into consideration, it is revealed that strong intermolecular π-π stacking induced by planar triphenylene and triphenyltriazine units renders TPTRZ and TPPTRZ small energetic and positional disorder parameters, and results in their high electron mobilities thereby. By further enhancing intermolecular π-π stacking, ETMs with even higher electron mobilities can thus be anticipated. | Minghan Cai Chongguang Zhao Dongdong Zhang Xiaozeng Song Lian Duan | 2019 | Science China Chemistry2019，62，6： | 0 |
