| 1 | An overview of the use of plastic-film mulching in China to increase crop yield and water-use efficiency显示文摘Since 1990,crop yields have stagnated in many parts of the world,posing a significant challenge to global food security[1].As such;innovative solutions are needed to increase the resource-use efficiency of cropping systems to produce more grains per unit area. | Dongbao Sun Haigang Li Enli Wang Wenqing He Weiping Hao Changrong Yan Yuzhong Li Xurong Mei Yanqing Zhang Zhanxiang Sun Zhikuan Jia Huaiping Zhou Tinglu Fan Xucheng Zhang Qin Liu Fengju Wang Chaochun Zhang Jianbo Shen Qingsuo Wang Fusuo Zhang | 2020 | National Science Review2020，7，10： | 19 |
| 2 | Joining dense Si3N4 to porous Si3N4 by using an anorthite based glass-ceramic显示文摘This study focuses on the design,characterization and testing of a novel anorthite based glass-ceramic solder for joining dense Si3N4 and porous Si3N4 ceramic.It was found that the glass solder possesses a favorable wetting ability on two ceramic surfaces.Additionally,the influence of crystallization treatment on the microstructure and shear strength of joints was investigated.The results showed that CaAl2 Si2O8 was the main product in the seam.After crystallization treatment,the crystallinitiy of the seam and shear strength of joints were improved obviously.The shear strength of joints after crystallization was 52 MPa at room temperature,and it increased to 59 MPa at 850℃.Finally,the joining mechanism of the dense Si3N4/glass-ceramic/porous Si3N4 bonded joints was proposed.Intergranular diffusion of elements was identified as the main mechanism of bonding in the interface of dense Si3N4/glass-ceramic.In the porous Si3N4 side,the bonding was achieved by infiltration that was controlled by capillarity and resistance of the viscous forces. | FANG Jian ZHANG Jie LIU ChunFeng SUN LiangBo GUO SongSong WANG DongBao | 2020 | Science China(Technological Sciences)2020，63，8： | 1 |
| 3 | Cascaded DNA circuits-programmed self-assembly of spherical nucleic acids for high signal amplification显示文摘Signal amplification is an important issue in DNA nanotechnology and molecular diagnostics.In this work,we report a strategy for the catalytic self-assembly of spherical nucleic acids(SNAs)programmed by two-layer cascaded DNA circuits through integrating an entropy-driven catalytic network,a catalytic hairpin assembly circuit,and a facile SNA assembly-based reporter system.This integrated system could implement^100,000-fold signal amplification in the presence of 1 pM of input target.Possessing powerful amplification ability of nucleic acid signal,our strategy should be of great potential in fabricating more robust dynamic networks to be applied for signal transduction,DNA computing,and nucleic acid-based diagnostics. | Xiang Li Dongbao Yao Junxiang Zhou Xiang Zhou Xianbao Sun Bing Wei Chengxu Li Bin Zheng Haojun Liang | 2020 | Science China Chemistry2020，63，1： | 0 |
