锂金属负极凭借高理论容量和低电化学电位,一直被誉为最具潜力的负极材料。然而,锂金属目前仍面临着锂枝晶不可控生长的风险,这严重影响了锂金属电池的循环寿命和安全性能,阻碍了其在实际生产中的应用。目前,改善锂金属负极性能的研究主要集中在SEI膜的调控、构建锂复合结构和引入固态电解质等3个方面。本文综述了多种策略在锂金属负极性能优化中的研究现状,展望了锂金属负极在未来储能领域的发展趋势。

After spinal cord injury, there is an extensive infiltration of immune cells, which exacerbates the injury and leads to further neural degeneration. Therefore, a major aim of current research involves targeting the immune response as a treatment for spinal cord injury. Although much research has been performed analyzing the complex inflammatory process following spinal cord injury, there remain major discrepancies within previous literature regarding the timeline of local cytokine regulation. The objectives of this study were to establish an overview of the timeline of cytokine regulation for 2 weeks after spinal cord injury, identify sexual dimorphisms in terms of cytokine levels, and determine local cytokines that significantly change based on the severity of spinal cord injury. Rats were inflicted with either a mild contusion, moderate contusion, severe contusion, or complete transection, 7 mm of spinal cord centered on the injury was harvested at varying times post-injury, and tissue homogenates were analyzed with a Cytokine/Chemokine 27-Plex assay. Results demonstrated pro-inflammatory cytokines including tumor necrosis factor α, interleukin-1β, and interleukin-6 were all upregulated after spinal cord injury, but returned to uninjured levels within approximately 24 hours post-injury, while chemokines including monocyte chemoattractant protein-1 remained upregulated for days post-injury. In contrast, several anti-inflammatory cytokines and growth factors including interleukin-10 and vascular endothelial growth factor were downregulated by 7 days post-injury. After spinal cord injury, tissue inhibitor of metalloproteinase-1, which specifically affects astrocytes involved in glial scar development, increased more than all other cytokines tested, reaching 26.9-fold higher than uninjured rats. After a mild injury, 11 cytokines demonstrated sexual dimorphisms; however, after a severe contusion only leptin levels were different between female and male rats. In conclus

以8个品种金银花的枝和叶为研究对象，建立8种酚酸类成分的高效液相色谱检测方法，测定样品中酚酸类成分的含量特征，将含量测定结果经聚类分析、因子综合分析及偏最小二乘判别分析(PLS-DA)等多元统计学方法评价。结果表明，建立的金银花枝和叶中8种酚酸类成分的含量测定方法稳定可靠简便。8个品种金银花枝和叶中的酚酸成分总变化范围分别为19.4162～33.6684 mg·g-1、40.9900～80.3068 mg·g-1。不同品种间酚酸类成分总含量差异较大，枝和叶中均为‘北花一号’的总含量最高，‘巨花一号’的总含量最低。聚类分析发现，金银花枝中，北花一号单独聚为一类，其各组分含量高于其他品种；因子综合分析表明，北花一号综合得分>1；PLS-DA分析筛选出异绿原酸A、异绿原酸C、阿魏酸和绿原酸可能是引起枝的酚酸含量差异的主要成分。金银花叶中，北花一号和九丰一号聚为一类，且这两个品种因子综合分析得分>1；PLS-DA分析筛选出绿原酸、咖啡酸和阿魏酸可能是引起叶的酚酸含量差异的主要成分。总之，不同品种金银花枝和叶的主要酚酸类成分特征存在差异，就酚酸类成分而言，北花一号和九丰一号的枝和叶更有优势。本研究为金银花枝和叶的利用提供了科学依据。

影响评价在全球能源转型中发挥重要作用,为识别与管理可再生能源项目影响提供理论知识。然而,对于影响评价工作在可再生能源开发方面的实际成效一直存在争议。本文基于对加拿大风能发展影响评价应用的内容分析,探讨分析了风能项目中通常评估的环境和社会影响以及提出的缓解方案。结果显示,包括缓解措施在内,生物物理影响与社会影响之间存在着相当大的不平衡。相比于社会影响,影响评价在生物物理影响方面包含更多的解决办法,其影响与缓解办法的比率为1∶4.3,而社会影响方面仅为1∶1.3。大多数缓解办法侧重于最大限度地减少影响,其次是避免影响,而在时间、实施方法和责任方面描述并不清晰。尽管存在共同影响,但跨项目的缓解措施过于模糊或不精确,无法支持评估中的可转移实践,无法提高效率。改进对可再生能源项目影响和缓解方案的理解,并不断在项目中积累经验,是推进影响评价在向可再生能源过渡中发挥作用的基础。
