| 5 | 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 |
| 6 | 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 |
| 7 | Highly stable, active and recyclable solid acid catalyst based on polymer-coated magnetic composite particles显示文摘A facile approach has been adopted for coating cross-linked polystyrene(PS) shells on the surface of Fe304 magnetic clusters using reflux-precipitation polymerization(RPP).Treating the PS shell with chlorosulfonic acid yields magnetic composite particles with acid functionality.By adjusting the amount and proportion of monomers(styrene and divinylbenzene),the obtained magnetic composite particle solid acid(MPM-5 S) exhibits a saturation magnetization value of 18 emu/g,a specific surface area of 243 m^2/g and an acid density of 2.113 mmol/g.The MPM-5 S magnetic solid acid catalyst was evaluated for esterification of oleic acid with methanol to prepare biodiesel.Under mild conditions,the conversion of oleic acid reached 91%,which was much higher than the catalytic activity of Amberlyst-15 and close to the catalytic activity of concentrated H2 SO4.The solid acid catalyst can be recovered by magnetic separation and reused three times maintaining over 95% of its initial catalytic activity.Additionally,the solid acid can be used to catalyze the dehydration of fructose to 5-hydroxymethylfurfural. | Jianxin Luo Xucheng Zhang Chunyan Zhang Tao Wang Xue Chen Hongyu Chen Steve King Changchun Wang | 2019 | Chinese Chemical Letters2019,30,12: | 2 |

| 9 | Chinese word segmentation with local and global context representation learning显示文摘A local and global context representation learning model for Chinese characters is designed and a Chinese word segmentation method based on character representations is proposed in this paper.First,the proposed Chinese character learning model uses the semantics of local context and global context to learn the representation of Chinese characters.Then,Chinese word segmentation model is built by a neural network,while the segmentation model is trained with the character representations as its input features.Finally,experimental results show that Chinese character representations can effectively learn the semantic information.Characters with similar semantics cluster together in the visualize space.Moreover,the proposed Chinese word segmentation model also achieves a pretty good improvement on precision,recall and f-measure. | 李岩 Zhang Yinghua Huang Xiaoping Yin Xucheng Hao Hongwei | 2015 | High Technology Letters2015,21,1: | 2 |
| 10 | EFFECTIVE NUMERICAL METHODS FOR ELASTO-PLASTIC CONTACT PROBLEMS WITH FRICTION显示文摘Several effective numerical methods for solving the elasto-plastic contact problems with friction are pres-ented.First,a direct substitution method is employed to impose the contact constraint conditions on condensed finite ele-ment equations,thus resulting in a reduction by half in the dimension of final governing equations.Second,an algorithmcomposed of contact condition probes and elasto-plastic iterations is utilized to solve the governing equation,whichdistinguishes two kinds of nonlinearities,and makes the solution unique.In addition,Positive-Negative Sequence Modifica-tion Method is used to condense the finite element equations of each substructure and an analytical integration is intro-duced to determine the elasto-plastic status after each time step or each iteration,hence the computational efficiency is en-hanced to a great extent.Finally,several test and practical examples are pressented showing the validity and versatility ofthese methods and algorithms. | Wang Xucheng Chang Liangming Cen Zhangzhi (Department of Engineering Mechanics,Tsinghua University) | 1990 | Acta Mechanica Sinica1990,6,4: | 2 |
