Interfacial engineering to alter the configuration of active sites in heterogeneous catalysts is a potential strategy for activity enhancement,but it remains unelucidated for metal-organic frameworks(MOFs).Here,we demonstrate that the surface of two-dimensional Co-based MOF is modified by decorating Ag quantum dots(QDs)simply through in-situ reduction of Ag+*** oxygen evolution reaction(OER),it reveals that the catalysis is mediated by the reversible redox of Co sites between Co^(3+) and Co^(4+) states coupling with transfer of OH*** decoration of Ag QDs decreases the redox potential of Co sites,and thus effectively decreases the overpotential of *** TOFs of Co sites are increased by 77 times to reach 5.4 s^(-1) at an overpotential of 0.35 *** attribute the activity enhancement to the tuning of the coupling process between Co sites and OHions during the redox of Co sites by Ag QDs decoration based on Pourbaix analysis.

利用辽河西部凹陷沙河街组三段中亚段分析实验测试数据和层次分析法,通过对多元页岩油气地质数据进行无量纲化和规则化处理,发现可以将其整合为具有"综合有利因子"意义的无量纲特征值,从而实现对研究区页岩油气勘探有利程度的定量化评价,同时发现对于西部凹陷沙河街组三段中亚段而言,存在中部和南部两个相对有利程度更高有利于页岩油气勘探评价井实施的区域。该方法具有较强的工具意义,可以简明清晰地凸显页岩油气多元地质信息,为页岩油气地质数据分析提供了一种有效的方法和技术思路。

研究新疆准噶尔盆地南缘托斯台地区构造演化与构造动力学成因机理。对托斯台地区进行了野外地质调查与构造剖面实测,发现托斯台地区构造复杂,褶皱、断裂、不整合共同存在。托斯台断裂与小煤窑沟断裂都为正断层,共同组合成地垒式背斜构造;但2条断裂带构造变形强烈,出现挤压构造透镜体和劈理带。该现象表明托斯台地区经历了多期构造活动,早期(燕山期)处于伸展构造动力学环境,形成地垒式背斜构造;晚期(喜马拉雅期)处于近南北向挤压构造动力学环境,形成断裂带内挤压构造透镜体与强烈构造变形带。

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.
