| 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 | Long-term storage of lipid-like nanoparticles for mRNA delivery显示文摘Lipid-like nanoparticles(LLNs)have been extensively explored for messenger RNA(mRNA)delivery in various biomedical applications.However,the long-term storage of these nanoparticles is still a challenge for their clinical translation.In this study,we investigated a series of conditions for the long-term storage of LLNs with encapsulation of mRNA.We evaluated the stability of LLNs with different concentrations of cryoprotectants(sucrose,trehalose or mannitol)under the conditions of freezing or lyophilization processes.Through in vitro and in vivo mRNA delivery studies,we identified the optimal storage condition,and found that the addition with 5%(w/v)sucrose or trehalose to LLNs could remain their mRNA delivery efficiency for at least three months in the liquid nitrogen storage condition. | Pengxuan Zhao Xucheng Hou Jingyue Yan Shi Du Yonger Xue Wenqing Li Guangya Xiang Yizhou Dong | 2020 | Bioactive Materials2020，5，2： | 3 |
| 3 | Enhancement of oxygen reduction reaction activity by grain boundaries in platinum nanostructures显示文摘Systematic control of grain boundary densities in various platinum(Pt)nanostructures was achieved by specific peptide-assisted assembly and coagulation of nanocrystals.A positive quadratic correlation was observed between the oxygen reduction reaction(ORR)specific activities of the Pt nanostructures and the grain boundary densities on their surfaces.Compared to commercial Pt/C,the grain-boundary-rich strain-free Pt ultrathin nanoplates demonstrated a 15.5 times higher specific activity and a 13.7 times higher mass activity.Simulation studies suggested that the specific activity of ORR was proportional to the resident number and the resident time of oxygen on the catalyst surface,both of which correlate positively with grain boundary density,leading to improved ORR activities. | Enbo Zhu Wang Xue Shiyi Wang Xucheng Yan Jingxuan Zhou Yang Liu Jin Cai Ershuai Liu Qingying Jia Xiangfeng Duan Yujing Li Hendrik Heinz Yu Huang | 2020 | Nano Research2020，13，12： | 3 |
