| 1 | Fabrication of Ti/Al/Mg laminated composites by hot roll bonding and their microstructures and mechanical properties显示文摘Ti/Al/Mg laminated composites were successfully fabricated by hot roll bonding.The effects of the rolling reduction on the microstructural evolution and mechanical properties of the composites were explored.The results show that Ti/Al/Mg laminated sheets exhibit good interfacial bonding.The rolling reduction has a significant effect on the deformation inhomogeneity through the thickness of the Al layer.The initial grains of the Al layer near the Ti/Al interface are fragmented into fine equiaxed grains,and the grains at the center and near the Al/Mg interface are elongated.The R-cube shear texture of the Al layer forms near the Ti/Al interface and permeates into the center layer in the samples with greater rolling reductions.The b-fiber rolling texture of the Al layer is observed near the Al/Mg interface and increases with the increase of rolling reduction.The stress–strain curves indicate that the fracture appears first in the Mg layer.With the increasing rolling reduction,the ultimate tensile and yield strength values increase,and the elongation up to the Mg layer fracture decreases. | Pengju WANG Zejun CHEN Hongtao HUANG Jianshu LIN Boxin LI Qing LIU | 2021 | Chinese Journal of Aeronautics2021，34，8： | 4 |
| 2 | Single-cell RNA-seq of Lotus japonicus provide insights into identification and function of root cell types of legume显示文摘The roots of legume plant play a crucial role in nitrogen fixation. However, the transcriptomes of different cell types of legume root and their functions remain largely unknown. Here, we performed single-cell RNA sequencing and profiled more than 22,000 single cells from root tips of Lotus japonicus, a model species of legume.We identified seven clusters corresponding to seven major cell types, which were validated by in situ hybridization. Further analysis revealed regulatory programs including phytohormone and nodulation associated with specific cell types, and revealed conserved and diverged features for the cell types. Our results represent the first single-cell resolution transcriptome for legume root tips and a valuable resource for studying the developmental and physiological functions of various cell types in legumes. | Zhanmin Sun Sanjie Jiang Dan Wang Linxia Li Boxin Liu Qifan Ran Lizhen Hu Junbo Xiong Yixiong Tang Xiaofeng Gu Yanmin Wu Zhe Liang | 2023 | Journal of Integrative Plant Biology2023，65，5： | 0 |
