Electrochemical and Raman Spectroscopy Studies of the Electric Double Layer at “Electrode/Ionic Liquid” Interface [PDF]

open access: yes, 2015
“电极/溶液”界面是各种电化学反应发生的场所,因此对界面结构和性质的研究不仅具有基础科学意义,而且能对实际应用起到指导作用。离子液体是一种新型溶剂,由于其具有蒸汽压几乎为零、导电性良好、电化学窗口宽等优点,离子液体被越来越多地应用于电化学以及其它领域,对“离子液体/电极”界面的研究也逐渐兴起,近十年来在理论和实验方面都有一定的进展,但仍需要更多的研究解决目前存在的问题:一方面,目前对离子液体界面的光谱表征集中在多晶或者粗糙电极上,电极表面结构的不确定性使结果分析和理论计算较为复杂 ...

显微结构对瓷绝缘子钢脚力学性能及运行可靠性的影响

open access: yesDianci bileiqi, 2022
输电线路线盘形悬式绝缘子掉串事故大多源于钢脚球头部位的断裂。在对国内两个厂家的4种盘形悬式绝缘子用钢脚开展成分、显微组织结构及力学性能测试分析的基础上,采用有限元分析软件对相应钢脚进行静力学分析及疲劳寿命计算。研究表明,这4种钢脚均含有氧化物、硫化物夹杂物及大块的铁素体,力学性能达不到相关国家标准的要求。有限元模拟证实在绝缘子服役条件下,钢脚球头部位存在应力集中,导致钢脚疲劳寿命降低。钢脚材料冶金质量不佳,不合理热处理工艺下显微组织不良,加之在导线覆冰、舞动等恶劣条件下,钢脚球头部位承受大的循环应力 ...

Study on the interactions of typical PAHs and their metabolites with serum albumin and their controlling ways using cyclodextrins [PDF]

open access: yes, 2016
血清白蛋白是血浆中含量最丰富的运输蛋白,对血液中许多内、外源物质具有广普的结合能力,具有重要的生理功能。多环芳烃(PolycyclicAromaticHydrocarbons,PAHs)及其代谢物可与血清白蛋白形成稳定的加合物,由此随血液循环转运分布至各组织器官,引起毒性效应。该结合过程也可对血清白蛋白的结构和功能产生不利影响。因此,深入研究PAHs及其代谢物与血清白蛋白的结合作用,探究PAHs对血清白蛋白结构和功能的影响及寻求该结合作用的调控方式对了解PAHs在生物体内的赋存状态、毒性强度及致毒机制 ...
