The development of renewable and affordable energy is crucial for building a sustainable society. In this context, establishing a sustainable infrastructure for renewable energy requires the integration of energy storage, specifically use of renewable hydrogen. The hydrogen evolution reaction (HER) of electrochemical water splitting is a promising method for producing green hydrogen. Recently, two-dimensional nanomaterials have shown great promise in promoting the HER in terms of both fundamental research and practical applications due to their high specific surface areas and tunable electronic properties. Among them, molybdenum disulfide (MoS2), a non-noble metal catalyst, has emerged as a promising alternative to replace expensive platinum-based catalysts for the HER because MoS_(2)has a high inherent activity, low cost, and abundant reserves. At present, greatly improved activity and stability are urgently needed for MoS_(2)to enable wide deployment of water electrolysis devices. In this regard, efficient strategies for precisely modifying MoS_(2)are of interest. Herein, the progress made with MoS_(2)as an HER catalyst is reviewed, with a focus on modification strategies, including phase engineering, morphology design, defect engineering, heteroatom doping, and heterostructure construction. It is believed that these strategies will be helpful in designing and developing high-performance and low-cost MoS2-based catalysts by lowering the charge transfer barrier, increasing the active site density, and optimizing the surface hydrophilicity. In addition, the challenges of MoS_(2)electrocatalysts and perspectives for future research and development of these catalysts are discussed.

欧盟共同移民与庇护政策是欧洲一体化的重要组成部分,2015年的欧洲难民危机暴露出该政策的诸多缺陷,此后欧盟寻求改革却屡陷困境。依据后功能主义理论,欧盟成员国的民族国家身份认同与欧盟认同兼容性有限,在面对欧盟外国家移民群体时,排斥性的民族国家身份认同更是占据主导。因此,欧盟始终难以健全既公正团结又稳定灵活的共同移民与庇护政策体系。俄乌冲突爆发后,成员国积极接纳与安置乌克兰难民,实际上是对乌克兰公民展现出包容性的民族国家身份认同。欧盟为了提高区域内部政策一致性,在移民和难民问题上或许只能突出欧盟内外分界,共同移民与庇护政策在未来也会愈发侧重外部解决路径。

在人民币发行与流通管理中,激励商业银行等私营金融机构履行其全额清分义务,减少重复调运有利于缓解中央银行在现金发行与清分处理上的成本压力。本文基于人民币现金闭环供应链框架,构建了商业银行的现金运行成本模型,分析了不同类型的商业银行在弹性罚款机制下现金清分与调运的最优策略,证明了该罚款机制能够激励商业银行对回笼现金进行全额清分,且对不同存取业务的银行具有奖励与惩罚双重作用。通过数值算例,深入讨论了弹性罚款机制对商业银行的重复调运量和现金运行成本的影响效果。研究结果表明:在弹性循环罚款和央行现行的代理发行库的双重机制下,商业银行重复调运量的降低幅度随单位押运成本的增加而增加,随现金保管价格和私人清分价格的降低而增加。对商业银行的现金运行成本的影响效果与央行清分服务价格同向变化,与代理发行库现金保管价格和私人清分价格成反向关系。

Ovarian endometrioma（OE）, also known as “chocolate cysts,” is a cystic mass that develops in the ovaries due to endometriosis and is a common gynecological condition characterized by the growth of endometrial tissue outside the uterus, leading to symptoms such as dysmenorrhea, pelvic pain, and infertility. However, the precise molecular and cellular mechanisms driving this pathophysiology remain largely unknown, posing challenges for diagnosis and treatment. Here, we employed integrated single-cell transcriptomic profiling of over 52,000 individual cells from endometrial tissues of OE patients and healthy donors and identified twelve major cell populations. We identified notable alterations in cell type-specific proportions and molecular signatures associated with OE. Notably, the activation of IGFBP5+macrophages with pro-inflammatory properties, NK cell exhaustion, and aberrant proliferation of IQCG+and KLF2+epithelium are key features and may be the potential mechanisms underlying the pathogenesis of OE. Collectively, our data contribute to a better understanding of OE at the single cell level and may pave the way for the development of novel therapeutic strategies.
