      • 《流浪地球》中人类命运共同体的文化意蕴

        林雨晗(Yuhan Lin),李雪松(Xuesong Li),李莎(Sha Li),赵旭(Xu Zhao) YIXIN 출판사 2023 Journal of China Studies Vol.1 No.5

        电影《流浪地球》以中国式的叙事方式,创造性地讲述了面对世界末日危机,人类克服万难带着地球家园一起逃亡的动人故事。其中,贯穿全片的“人类命运共同体”理念不仅展现了中国的价值遵循,也为解决世界性难题提供了丰富启示。以《流浪地球》的影像呈现为切入点,分析影片中对于“人类命运共同体”理念的生动阐释:命运同行,大道与共;展现了中国独有的文化精神:家国情怀和集体主义价值信仰。探讨其带来的当代启示,坚持习近平文化思想的科学指引,以共同体愿景共创人类美好未来,以文化创新加强中国国际传播能力。 The movie Wandering Earth creatively tells the touching story of humanity overcoming all difficulties and fleeing together with their homeland on Earth in the face of the apocalyptic crisis, using a Chinese-style narrative. The concept of “a Community of Shared Future for Mankind” that runs through the entire film not only demonstrates China’s value adherence, but also provides rich inspiration for solving global problems. Starting from the visual presentation of Wandering Earth, analyze the vivid interpretation of the concept of “a Community of Shared Future for Mankind” in the film: shared destiny, shared path. It showcases the unique cultural spirit of China: patriotism and collectivist values and beliefs. Explore the contemporary revelations it brings, adhere to the scientific guidance of Xi Jinping’s cultural thought, create a better future for mankind with a community vision, and strengthen China’s international communication capacity with cultural innovation.

        Combining Ultrasound-Mediated Intracellular Delivery with Microfluidics in Various Applications

        Huang Guangyong,Lin Lin,Wu Shixiong,Dang Haojie,Cheng Xuesong,Liu Ying,You Hui 한국바이오칩학회 2024 BioChip Journal Vol.18 No.1

        Ultrasound-mediated intracellular delivery is one of the popular technologies based on membrane rupture at present. To date, ultrasound directly acts on a large number of cells to achieve cargo delivery and has been widely used in drug deliv-ery, disease therapy and other fields. However, the existing macroscopic methods can no longer meet the requirements of accurate tracking and analysis and are prone to extensive cell damage and even death. With the rapid advancements in microfl uidic technologies, the combination of ultrasound and microfluidics (CUM) technology can effectively improve the delivery efficiency and cell survival rates. This new technology has rapidly become a new direction and focus of research. Thus, we analysed the mechanism of sonoporation and the effect of acoustic waves in a microfluidic channel. In addition, we reviewed the application of these new technologies in terms of structure and fabrication of ultrasound transducers and microfl uidic devices. As regards our main objective, we hope to help researchers better understand the future developments and the challenges of new technologies. With this review, researchers can promote the development of new technologies to solve the current challenges of intracellular delivery and advance clinical applications.

        Study on complex flow law near polymer flooding wellbores and adaptability evaluation of shaped charges

        Jianguang Wei,Xidong Ren,Hongyan Shao,Yuanyuan Ma,Xuemei Liu,Xuesong Lin 한국자원공학회 2016 Geosystem engineering Vol.19 No.5

        The flow law near polymer flooding wellbores under the condition of perforation is very complex and there are many types of shaped charges. In this study, a non-Darcy flow model near polymer flooding wellbores was given, and a flow experiment was carried out to measure the resistance coefficient, residual resistance coefficient, and flow viscosity of the polymer solution in porous media under the conditions of different permeability and different polymer molecular weight. According to the results of numerical simulation, this paper calculated the flow efficiency of different types of shaped charges and evaluated the adaptability of different charges under polymer flooding condition. The results of this study have an important significance for guiding the optimization of shaped charges and the optimization design of perforating parameters.

      • <i>In Situ</i> Observation and Electrochemical Study of Encapsulated Sulfur Nanoparticles by MoS<sub>2</sub> Flakes

        Tang, Wei,Chen, Zhongxin,Tian, Bingbing,Lee, Hyun-Wook,Zhao, Xiaoxu,Fan, Xiaofeng,Fan, Yanchen,Leng, Kai,Peng, Chengxin,Kim, Min-Ho,Li, Meng,Lin, Ming,Su, Jie,Chen, Jianyi,Jeong, Hu Young,Yin, Xuesong American Chemical Society 2017 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.139 No.29

        <P>Sulfur is an attractive cathode material for next-generation lithium batteries due to its high theoretical capacity and low cost. However, dissolution of its lithiated product (lithium polysulfides) into the electrolyte limits the practical application of lithium sulfur batteries. Here we demonstrate that sulfur particles can be hermetically encapsulated by leveraging on the unique properties of two-dimensional materials such as molybdenum disulfide (MoS<SUB>2</SUB>). The high flexibility and strong van der Waals force in MoS<SUB>2</SUB> nanoflakes allows effective encapsulation of the sulfur particles and prevent its sublimation during <I>in situ</I> TEM studies. We observe that the lithium diffusivities in the encapsulated sulfur particles are in the order of 10<SUP>–17</SUP> m<SUP>2</SUP> s<SUP>–1</SUP>. Composite electrodes made from the MoS<SUB>2</SUB>-encapsulated sulfur spheres show outstanding electrochemical performance, with an initial capacity of 1660 mAh g<SUP>–1</SUP> and long cycle life of more than 1000 cycles.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2017/jacsat.2017.139.issue-29/jacs.7b05371/production/images/medium/ja-2017-05371c_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja7b05371'>ACS Electronic Supporting Info</A></P>
