The development and utilization of renewable clean energy can effectively solve the two major problems of energy and environment. As an efficient power generation device that converts hydrogen energy into electric energy, fuel cell has attracted more and more attention. For fuel cells, the oxygen reduction reaction(ORR) at the cathode is the core reaction, and the design and development of high-performance ORR catalysts remain quite challenging. Since the microenvironment of the active center of single atom catalysts(SACs) has an important influence on its catalytic performance, it has been a research focus to improve the ORR activity and stability of electrocatalysts by adjusting the structure of the active center through reasonable structural regulation methods. In this review, we reviewed the preparation and structure–activity relationship of SACs for ORR. Then, the structural precision regulation methods for improving the activity and stability of ORR electrocatalysts are discussed. And the advanced in-situ characterization techniques for revealing the changes of active sites in the electrocatalytic ORR process are summarized. Finally, the challenges and future design directions of SACs for ORR are discussed. This work will provide important reference value for the design and synthesis of SACs with high activity and stability for ORR.

肿瘤电场治疗是一种新的治疗恶性实体肿瘤的疗法,多采用电场仿真分析不同参数的肿瘤电场治疗在瘤体上产生的电场分布。但目前,由于仿真模型构建技术路线较难复现或实现成本较高,因此本研究采用常用的软件工具建立了易实现的高精度肿瘤电场治疗有限元仿真模型,模型精度在1 mm^(3)水平。本研究利用该仿真模型开展了不同组织电学参数、电极配置等因素分析,研究结果显示,对肿瘤内电场分布存在影响的因素包括:头皮、头骨电导率的变化(瘤体治疗场最高变化21.0%)、肿瘤电导率的变化(瘤体治疗场最高变化157.8%)和不同的电极位置及组合(瘤体治疗场最高变化74.2%)。综上,本文研究结果验证了所提建模方法的可行性与有效性,或可为今后的肿瘤电场治疗仿真分析和临床应用提供重要参考。

Plant receptor-like protein kinases(RLKs) are transmembrane proteins with an extracellular domain and an intracellular kinase domain, which enable plant perceiving diverse extracellular stimuli to trigger the intracellular signal transduction. The somatic embryogenesis receptor kinases(SERKs) code the leucine-rich-repeat receptor-like kinase(LRR-RLK), and have been demonstrated to associate with multiple ligand-binding receptors to regulate plant growth, root development, male fertility, stomatal development and movement, and immune responses. Here, we focus on the progress made in recent years in understanding the versatile functions of Arabidopsis SERK proteins, and review SERK proteins as co-receptor to perceive different endogenous and environmental cues in different signaling pathway, and discuss how the kinase activity of SERKs is regulated by various modification.
