Study on Li3BO3 Interface Modification of Garnet Solid Electrolyte

石榴石固体电解质由于其高的离子电导率,对锂金属稳定等优点成为了下一代高性能锂电池的重要研究方向之一。但锂金属负极界面浸润性与锂枝晶问题限制了其应用。本文通过简单的液相沉积结合高温烧结的方法,在石榴石固体电解质片表面构建了一层稳定的硼酸三锂(Li3BO3)修饰层。研究表明,Li3BO3修饰层可以有效改善石榴石固体电解质与锂金属负极界面接触,促进锂的均匀沉积/溶出,从而抑制锂枝晶生长,提高界面稳定性。Li3BO3修饰后石榴石电解质片与锂金属之间紧密结合,Li/石榴石界面阻抗由修饰前的1780 Ω·cm2降低至58 Ω·cm2。得益于界面接触的改善,Li3BO3修饰后的LLZTO电解质组装的对称电池可以在0.1 m·cm-2的电流密度下稳定工作超过700 h。而未修饰的对称电池在0.05 mA·cm-2的电流密度下短时间工作即出现微短路现象。Garnet solid-state electrolytes have become the research hotspot due to their high ionic conductivity, wide electrochemical stability window and good air stability. However, there are still a series of problems to be solved. The poor contact between the lithium (Li) metal and garnet pellet make it difficult to build stable ion diffusion channels, resulting in large interfacial resistance. The continuous growth of lithium dendrites can penetrate the electrolyte pellet and cause a short circuit in the solid-state battery. Herein, a novel strategy is proposed to improve the wettability of LLZTO electrolyte with Li metal, via interfacial modification of LLZTO electrolyte with tri-lithium borate (Li3BO3). Li3BO3 is chemically stable with Li metal and effective to improve the wettability between Li and LLZTO pellet. A stable and even Li3BO3 interfacial layer was constructed on the LLZTO electrolyte surface by liquid-phase deposition combing with high temperature sintering. The low melting point (700℃) of Li3BO3 facilitated the formation of a dense and uniform coating layer. SEM images show that the Li3BO3 layer was about 2.5 μm thick and completely covered the pellet surface. Intimate contact between Li metal and LLZTO electrolyte could be realized after the Li3BO3 interfacial modification, which was confirmed by SEM analysis and wettability experiment. Benefiting from the significantly improved interfacial contact, the interfacial impedance was dramatically reduced from 1780 Ω·cm2 of Li/LLZTO interface to 58 Ω·cm2 of Li/LBO-LLZTO interface. The Li|LBO-LLZTO|Li symmetric cell could produce a low overpotential and work stably at the current density of 0.1 mA·cm-2 for more than 700 h. By contrast, the Li|LLZTO|Li symmetric cell displayed high overpotential and was short circuited after 20 min of lithium plating/stripping at the current density of 0.05 mA·cm-2. Our results show that Li3BO3 interfacial modification is an effective approach to improve the wettability and interfacial stability between Li metal and garnet electrolyte, which is a key to the successful use of solid-state battery.国家重点研发计划项目(2018YFB0905400);国家自然科学基金项目(21875196);国家自然科学基金项目(21935009);国家自然科学基金项目(U1732121);福建省引导性计划项目(2019H0003);厦门大学大学生创新创业训练计划项目(S201910384404)通讯作者:龚正良E-mail:[email protected]:Zheng-LiangGongE-mail:[email protected]厦门大学能源学院,福建 厦门 361005College of Energy, Xiamen University, Xiamen 361005, Fujian, Chin

Influence of Resveratrol on Performance of Long-Term Storage’s Lithium-Ion Battery Electrolyte

锂离子电池电解液从制造完成到使用,一般都会经历灌装、运输和贮存的过程,了解长期贮存过程对锂离子电池电解液性能的影响,对锂离子电池的生产具有一定的理论指导意义。本文运用电化学阻抗谱(EIS)测试并结合循环伏安法(CV)测试、充放电测试、扫描电子显微镜(SEM)等研究了1 mol·L-1 LiPF6-EC:EMC基础电解液中添加不同浓度白藜芦醇(RES)时,在长期贮存过程中对石墨电极性能的影响及机制。研究结果表明,新鲜的基础电解液在经历6个月的贮存后,石墨电极在其中无论是可逆循环容量还是循环稳定性(容量保持率)均出现大幅度的下降。这主要是由于在经历6个月贮存后的基础电解液中,石墨电极表面形成的 SEI 膜较厚,进而导致锂离子嵌入过程的不稳定造成的。在基础电解液中添加不同浓度的白藜芦醇均能有效抑制电解液长期贮存造成的石墨电极在其中电化学性能的下降,当基础电解液中含有200 ppm白藜芦醇经历6个月贮存后,石墨电极无论是可逆容量还是循环性能稳定性甚至优异于在新鲜的电解液中。Electrolyte of lithium-ion battery usually goes through processes of filling, transportation and storage from the completion of manufacture to the use. Understanding the influence of long-term storage process on performance of lithium-ion battery electrolyte is of theoretical significance for production of lithium-ion battery. Scanning electron microscope (SEM) images showed that the solid electrolyte interface (SEI) film formed on the surface of the graphite electrode was thicker in the base electrolyte after 6 months of storage. The charge/discharge test results showed that the reversible cycle capacity and cycle stability (capacity retention rate) of graphite electrode decreased significantly after 6 months of storage. This might be due to the thicker SEI film formed on the surface of the graphite electrode, which in turn led to the instability of the lithium-ion intercalation process. When the base electrolyte containing 200 ppm resveratrol was stored for 6 months, the reversible capacity and cycle performance stability of the graphite electrode were even better than those in fresh base electrolyte. The results of electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) idicated that adding 200 ppm resveratrol to the base electrolyte could effectively suppress the decline in the electrochemical performance of the graphite electrode caused by long-term storage of the base electrolyte.国家自然科学基金项目(U1730136);中央高校基本科研业务费(2017XKQY062)通讯作者:庄全超E-mail:[email protected]:Quan-ChaoZhuangE-mail:[email protected]中国矿业大学材料与物理学院,江苏 徐州 221116Lithium ion battery lab, School of Materials & Physics, China University of Mining & Technology, Xuzhou 221116, Jiangsu, Chin

The Triple Defense of Practical Materialism

卜祥记，上海交通大学马克思主义学院特聘教授、博士生导师；刘雅兰，上海第二工业大学马克思主义学院讲师。【中文摘要】近40年来，国内学界针对实践唯物主义所展开的原则性批评集中在三个方面:实践唯物主义放弃了唯物主义基本立场、再度把实践原则神秘化以及并未在理论和实践上取得富有成效的成果。对此，我们必须做出如下澄清:实践唯物主义本质性地超越了认识论意义上的唯物主义和唯心主义、客观主义和主观主义之争，是把它们结合起来的真理;作为不同于理论哲学的实践哲学范式,实践唯物主义是马克思全新哲学立场的理论宣言，是走向唯物史观的理论中介;不论是作为新哲学范式的实践唯物主义,还是作为实践唯物主义具象化展开的唯物史观，它们都只是马克思用于破解资本主义之谜的理论准备和方法论工具，而不是马克思全部理论工作的宗旨所在。今天的马克思主义哲学研究,不应把马克思的哲学本身作为最主要的研究对象，而是要坚持实践唯物主义的实践性精神，运用唯物史观的基本立场和方法，反思紧迫的时代性课题。 【Abstract】In the past 40 years，the principled criticisms of practical materialism in the Chinese academic community have been focused on the following perception: Practical materialism has abandoned the basic standpoint of materialism，mystified the principle of practice once again，and failed to yield fruitful results in theory and practice. As such，we must clarify as follows ：Practical materialism essentially transcends the controversy between materialism and idealism and between objectivism and subjectivism in the sense of epistemology ；it is the truth that combines all of them. As a paradigm of practical philosophy as opposed to theoretical philosophy， practical materialism is the theoretical declaration of Marx's brand-new philosophical standpoint and the theoretical intermediary towards historical materialism. Both practical materialism as a new philosophical paradigm and historical materialism as a concrete development of practical materialism are only the theoretical preparations and methodological tools used by Marx to unravel the mystery of capitalism，rather than the purpose of all Marx's theoretical work. In the ongoing research on Marxist philosophy，we should not take Marx's philosophy itself as the main object of study ； rather，we should adhere to the practical spirit of practical materialism，adopt the fundamental standpoint and method of historical materialism，and reflect upon the most pressing issues

Constructing a Conceptural Framework for Governmental Internal Control from the Perspective of National Capacity

吴益兵,厦门大学管理学院副教授，管理学博士；廖义刚,江西财经大学会计学院教授、博士生导师，管理学博士。【中文摘要】党的十九大提出了推进国家治理体系和治理能力现代化的全面深化改革的总目标。政府内部控制是实现国家治理体系以及能力现代化的重要抓手，建立健全政府内部控制体系具有重要的意义。以福山的国家建构理论和王绍光国家能力理论为基础，可建立基于国家能力视角的政府内部控制框架。该政府内部控制框架包括三个层次的目标定义：基础性国家能力目标、国家公共管理能力目标和国家治理能力目标。在该体系中，政府内部控制要素同样包括控制环境、风险评估、控制活动、信息与沟通以及对控制的监督。政府内部控制的范围除了涵盖行政事业单位内部控制、财政内部控制和预算管理之外，还应该包括政府部门一般业务的内部控制。 【Abstract】 The 19th CPC National Congress set forth the general goal of carrying on reform to further modernize China's national governance system and governance capacity. Governmental internal control is an important starting point to modernize China's national governance system and governance capacity. Therefore，it is of great significance to establish and improve the conceptual framework of governmental internal control. Based on Francis Fukuyama's state - building theory and Wang Shaoguang's national capacity theory，a conceptual framework for governmental internal control can be developed from the perspective of national capacity.It consists of three levels of objectives ：basic national capacity,national public management capacity，and national governance capacity. Within this framework，the components of governmental internal control include the control environment，risk assessment，control activities，information，communication，and monitoring of control. The scope of governmental internal control not only covers the internal control of administrative institutions，financial internal control and budgetary management，but also includes the internal control of government departments’ general business.国家自然科学基金项目“‘圈子’文化视域下的审计行为与经济后果:基于会计师事务所内部审计师关系网络的研究”（72072077);国家自然科学基金项目“社会网络关系与审计行为：基于审计师与客户高管双边视角的研究”（71762015);福建省社会科学规划项目“保荐代表与签字会计师在IPO中的重复性合作研究” (FJ2020B046

Profiling PRMT methylome reveals roles of hnRNPA1 arginine methylation in RNA splicing and cell growth

百年校庆来临之际，细胞应激生物学国家重点实验室、药学院刘文教授团队在Nature子刊Nature Communications杂志上发表论文，揭示了精氨酸甲基转移酶家族蛋白介导的精氨酸甲基化修饰网络及其协同调控基因剪接和促癌机制。精氨酸甲基转移酶（protein arginine methyltransferase, PRMT）家族蛋白及其介导的精氨酸甲基化修饰与癌症的发生发展密切相关。团队研究证实PRMT4、PRMT5和PRMT7在乳腺癌、结直肠癌和前列腺癌临床样品中均呈现高表达，并且PRMTs的高表达和hnRNPA1精氨酸甲基化的富集以及异常的选择性剪接高度相关。在乳腺癌、结直肠癌和前列腺癌细胞中，PRMT4，PRMT5和PRMT7以及它们介导的hnRNPA1甲基化和剪接异构体能有效促进癌细胞生长。最后，团队研究发现特异性靶向PRMT4、PRMT5和PRMT7的活性小分子能有效抑制癌细胞的生长，且三者联合使用具有协同作用，这为相关癌症治疗提供了新的方向和途径。 药学院刘文教授为文章的通讯作者，课题组博士生李文娟、何耀辉和硕士生杨晶晶为共同第一作者。Numerous substrates have been identified for Type I and II arginine methyltransferases (PRMTs). However, the full substrate spectrum of the only type III PRMT, PRMT7, and its connection to type I and II PRMT substrates remains unknown. Here, we use mass spectrometry to reveal features of PRMT7-regulated methylation. We find that PRMT7 predominantly methylates a glycine and arginine motif; multiple PRMT7-regulated arginine methylation sites are close to phosphorylations sites; methylation sites and proximal sequences are vulnerable to cancer mutations; and methylation is enriched in proteins associated with spliceosome and RNA-related pathways. We show that PRMT4/5/7-mediated arginine methylation regulates hnRNPA1 binding to RNA and several alternative splicing events. In breast, colorectal and prostate cancer cells, PRMT4/5/7 are upregulated and associated with high levels of hnRNPA1 arginine methylation and aberrant alternative splicing. Pharmacological inhibition of PRMT4/5/7 suppresses cancer cell growth and their co-inhibition shows synergistic effects, suggesting them as targets for cancer therapy.This work was supported by the Ministry of Science and Technology of China (2020YFA0112300), National Natural Science Foundation of China (91953114,81761128015, 81861130370, 31871319, 91440112, 31422030, and 31371292), Fujian Province Health Education Joint Research Project (WKJ2016-2-09), Xiamen Science and Technology Project (3502Z20173022), Xiamen Science and Technology major projects (3502Z20171001-20170302), and the Fundamental Research Funds for the Central University (20720190145 and 2013121036) to W.

Beyond the “Tang and Song Transformation Theories”With a Discussion of Some Defects in the Current Research on Ancient Chinese History

成一农，云南大学历史与档案学院研究员、博士生导师，历史学博士。【中文摘要】虽然近十多年来以“唐宋变革论”为代表的各种“变革论”受到了各种质疑,但是这些质疑基本限于“变革论”的框架之内，并未指出“变革论”的真正的问题。大致而言,研究者需要意识到，“变革论”只是一种具有强烈主观性的历史认知，而不是既定的历史事实，因此讨论“变革论”是否成立并无太大的意义,更应当讨论的是隐藏在“变革论”背后的对人类历史进程的认知，由此才能深化对历史、历史学及其意义的思考。要做到这一点,需要强化对理论的讨论以及其他学科方法的了解，弱化对史料的依赖，由此中国学者才能成为历史研究的“设计师”而不是“工匠”。 【Abstract】Although various “transformation theories”，as typified by the “Tang and Song transformation theories”， have been questioned in the past decade，the questions are basically limited to the framework of “transformation theories” and do not point out the real problems in the “transformation theories”. In general，researchers should recognize that the “transformation theories” are only strongly subjective historical perceptions rather than established historical facts； therefore ，it is not very meaningful to discuss whether these “transformation theories” are valid or not. It is more important to discuss the cognition of human historical process that lies behind these “transformation theories”，so that we can deepen our thinking about history，historiography and their meaning. To this end，we need to strengthen theoretical discussions， understand other disciplines’ methods，and weaken our reliance on historical sources，so that Chinese scholars can become “designers” rather than “craftsmen” of historical research.国家社会科学基金重大项目“中国国家图书馆所藏中文古地图的整理与研究”（16ZDA117

Macroeconomic Forecasts for China in 2021—2022

The results show that China's economy is expected to show a trend of “rebounding and stabilizing”，during which periodic inflow and outflow of overseas orders will cause certain seasonal fluctuations. Under the new pattern of double cycle development， how to stimulate residents’ coosumption is undoubtedly the central issue. The policy simulation of whether increasing public consumption can lead to household consumption shows that，under the condition of constant total fiscal expenditure， although the increase of government public consumption can increase the proportion of final consumption in GDP，it has a crowding-out effect on household consumption. Second，the way to raise household income is better than increasing public spending.Therefore，in the context of the current weak growth of consumption，especially household consumption，the fundamental way to stimulate household consumption is to increase household income，rather than focus on improving the consumption environment or increasing government public consumption.国家社会科学基金一般项目“经济特征变化下的中国减税降费政策组合研究”（20BJY231);教育部重点研究基地重大项目“中国季度宏观经济模型（CQMM)的再拓展”（17JJD790014);教育部重点研究基地重大项目“深化财税体制改革与促进中国经济平穗增长”（18JJD790007)；教育部哲学社会科学重大课题攻关项目“供给侧结构改革的理论基础与政策思路研究”（16JZD016

Study on MXene-Carbon Black/Sulfur Composite in Integrated Electrode of Lithium-Sulfur Batteries

锂硫电池的实际能量密度不高和多硫化物（LiPSs）的穿梭效应等问题严重影响了该电池的实际应用。本文通过将二维的Ti3C2Tx Mxene纳米片与碳黑/硫（CB/S）材料进行混合,制备了Ti3C2Tx-CB/S正极材料并将其涂覆在商业隔膜（PP）上,最终获得了Ti3C2Tx-CB/S-PP一体式电极并用于锂硫电池。利用Ti3C2Tx纳米片对CB/S进行修饰,不仅能提高活性物质硫的导电性,还能对扩散的LiPSs进行物理阻挡和化学吸附。而一体式电极的设计有利于提高电池的能量密度。恒流充放电测试结果表明,Ti3C2Tx-CB/S-PP电极在0.1 C电流下的初始放电容量为1028.8 mAh·g-1,高于不含Ti3C2Tx的CB/S-PP电极的896.8 mAh·g-1。Ti3C2Tx-CB/S-PP电极还展示出了比基于传统铝箔集流体的Ti3C2Tx-CB/S-Al电极更好的循环稳定性,前者在0.5 C下400圈长循环测试中的每圈衰减率为0.072%,而后者则为更高的0.10%。本文利用Ti3C2Tx-CB/S构建一体式电极的策略为实现高性能和高能量密度的锂硫电池提供了新的研究方向。Lithium-sulfur (Li-S) batteries are considered as a promising energy storage device due to their ultrahigh theoretical energy density of 2500 Wh·kg-1 and low cost. However, the practical application of Li-S batteries is seriously limited by their low actual energy density, the shuttle effect of polysulfides (LiPSs), and the insulating nature of sulfur and lithium sulfides. Carbon materials have been developed in the design of sulfur hosts due to their adjustable pore structure and high electrical conductivity, but their non-polar surfaces have weak interactions with LiPSs. Herein, MXene-carbon black/sulfur (Ti3C2Tx-CB/S) composites were prepared and applied to the integrated electrodes of Li-S batteries. The CB/S was prepared via a melting-diffusion method and Ti3C2Tx MXene nanosheets were synthesized by etching Ti3AlC2 MAX with LiF/HCl. After mixing CB/S and Ti3C2Tx , Ti3C2Tx-CB/S cathode material was obtained and coated on commercial separator (PP) to prepare Ti3C2Tx-CB/S-PP integrated electrodes. On the one hand, the two-dimensional Ti3C2Tx nanosheets dispersed in the CB/S particles not only serve as multiple physical barriers to inhibit the diffusion of LiPSs, but also have strong chemical interactions with them, effectively alleviating the shuttle effect. Thus, Ti3C2Tx improves the conductivity of CB/S composite, which is beneficial to the reaction kinetics of the cathode. Furthermore, the design of Ti3C2Tx-CB/S-PP integrated electrode increases the energy density of Li-S batteries. X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were employed to analyze the structures, morphologies, and surface chemical composition of the synthesized materials. The results of constant current charge/discharge tests showed that Ti3C2Tx-CB/S-PP electrode achieved superior rate performance and cycling performance than CB/S-PP electrode. The initial discharge capacity of Ti3C2Tx-CB/S-PP electrode at 0.1 C current was 1028.8 mAh·g-1, higher than 896.8 mAh·g-1 of CB/S-PP electrode. The cycling test at 0.2 C indicated that Ti3C2Tx-CB/S-PP maintained a discharge capacity of 726.4 mAh·g-1 after 80 cycles, better than CB/S-PP (529.2 mAh·g-1). Moreover, due to the improved utilization of the active material at the interface between the cathode and the separator, Ti3C2Tx-CB/S-PP electrode also showed better cycling stability compared to the Ti3C2Tx-CB/S-Al electrode based on the traditional aluminum foil current collector. The capacity degradation rate of Ti3C2Tx-CB/S-PP was only 0.072% per cycle in a long-term cycling test of 400 cycles at 0.5 C, while that of Ti3C2Tx-CB/S-Al was 0.10%. The strategy of using Ti3C2Tx-CB/S to construct an integrated electrode provides a new direction for Li-S batteries with high performance and high energy density.广西重点研发计划项目(AB16380030);广西创新驱动重大专项(AA17204083);国家自然科学基金-联合基金重点研发项目(U1705252)通讯作者:沈培康E-mail:[email protected]:Pei-KangShenE-mail:[email protected].广西大学可再生能源材料协同创新中心,广西 南宁 5300042.广西大学化学化工学院,广西 南宁 5300041.

Tone of Media Coverage and Corporate Excess Cash Holdings

支晓强，中国人民大学商学院教授、博士生导师，管理学博士；周艳坤，中国人民大学商学院博士研究生。【中文摘要】近年来上市公司的超额现金持有现象引起了学界的普遍关注。媒体作为企业重要的外部治理机制，其报道不仅会影响投资者对公司的认知，也会影响公司各项决策行为。媒体报道数量体现的是媒体对企业的关注程度,而媒体报道语调更能反映出媒体的主观情感。考察媒体报道语调对公司超额现金持有行为的影响是一个富有意义的研究话题。以2007—2019年中国A股上市公司为研究样本,可实证检验媒体报道语调对公司超额现金持有的影响。研究发现,媒体报道语调能够显著地正向影响公司超额现金持有水平，即媒体报道语调越积极，公司超额现金持有水平越高，这一现象在市场竞争程度较大的企业和管理层较为保守的企业中更为明显。此外，拓展性检验还发现,媒体报道语调越积极的公司会降低股利支付,减少并购投资，并且公司的超额现金持有行为不会损害其市场价值。 【Abstract】Using a dataset of Chinese A-share listed companies from 2007 to 2019，this paper empirically examines the impact of tone of media coverage on corporate excess cash holdings. The study finds that tone of media coverage is significantly and positively associated with corporate excess cash holdings. It means that the more positive the tone of media coverage，the more cash held by company. The paper also finds that this phenomenon is more obvious in enterprises with a greater degree of market competition and in enterprises whose executives are conservative. The main results remain valid after a series of robustness tests. In addition，this paper also finds that companies whose media coverage is in the positive tone are more likely to reduce dividend payments and M&A investment，and that their market value will not be hurt by corporate excess cash holdings. This study extends the relevant literature in the field of media coverage and corporate cash holdings，and is of great practical significance for companies to formulate reasonable cash holdings policies.财政部会计名家培养工程；中国人民大学“双一流”跨学科重大创新规划平台——面向国家监督体系建设的审计人才培养跨学科交叉平台支持项

Discovery and Research of “Zheng He's Records”in Indonesia Cirebon's Traditional Manuscripts:Comparison of the Two Kronik Tionghoa of Semarang And Cirebon and Other Related Documents

Nevertheless，some scholars still have doubts about the authenticity of the material and the reliability of the narrative accounts related to Zheng He. During our field trip to Java，we found that two other traditional manuscripts of Cirebon {Nagom Krethabumi and Sajarah Wali) also mention Zheng He. Therefore，we translated the contents about Zheng He in the two manuscripts and added annotations. We compared the narrative of Zheng He's visit to Cirebon in Nagara Krethabumi with the narrative of Zheng He in the “Cirebon” part of the Kronik Tionghoa，finding that the two narratives correspond to each other. In addition ，we verified the details by comparing Chinese historical materials with existing research，further confirming the value of these two sources as historical materials evidencing Zheng He's expeditions
