Dual‐Functional Carbon Dots as Electrolyte Additives for Enhancing Cathode Catalysis and Anode Stability in Li–O2 Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Li–O2 batteries garner widespread attention owing to their remarkable theoretical specific capacity. Nevertheless, the feasible implementation of the system is hindered by sluggish cathode reaction kinetics and poor anode stability. Herein, the carbon dots (CDs) with ‐OH, ‐NH2, and ‐COOH groups are synthesized and employed as electrolyte ...

一字型接地体冲击散流机理研究

open access: yesDianci bileiqi, 2023
为了研究接地体在遭受雷电流时的暂态散流规律,以一字型接地体为例进行了现场的冲击注流试验,选择不同幅值的冲击电流注入5 m长度铜覆扁钢的端部和中心,以及不同幅值的冲击电流注入5 m长度不锈钢包钢圆钢的端部,以总结一字型接地体在遭受冲击电流注入时的冲击散流规律。试验推理出土壤火花放电效应在一字型接地体散流时明显存在,并且接地体在散流时呈现出明显的端部效应,当端部注流时,首端和末端的散流比例高于中间导体约5%~15%,端部注流时的冲击电阻值比中心注流时大15%~25 ...

Encapsulation of Bi2S3 Within Multifunctional Sulfurized Polyacrylonitrile Matrix Enables High‐Performance Wide‐Temperature Sodium/Potassium‐Ion Batteries Through Solid–Solid Conversion

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT With high theoretical capacity and low cost, bismuth sulfide (Bi2S3) demonstrates considerable potential as an anode for sodium/potassium‐ion batteries (SIBs/PIBs). Unfortunately, significant volume variation, low electrical conductivity, and dissolution of polysulfides drastically weaken their intrinsic merits.

Return from exile: Mythology and heritage in American Born Chinese and its Disney adaptation

open access: yesPopular Culture Review, Volume 35, Issue 2, Page 228-237, Fall 2024.
Abstract Though American Born Chinese has received a significant degree of scholarly study, the prevalence of cultural exile in the text has not received sufficient attention. Said's theorization on exile provides a guide to examining the mindset of Jin, who willfully accepts exile from his Chinese‐American heritage because of how he feels neither ...

正直流电压下油纸绝缘针板电极局放流注仿真研究

open access: yesGaoya dianqi, 2018
为了更好地研究直流电压下油纸绝缘系统针板电极局部放电的电荷分布特性,文中基于流体动力学扩散—漂移方程和双极电荷传输方程搭建仿真模型用以模拟空间电荷的分布,研究了电荷产生的和流注发展的过程与放电特性,得到了局部放电过程中电荷,电场和电势的发展趋势。研究表明:油纸绝缘针板电极的局放过程分为流注击穿油隙与电荷在纸板上积累两个阶段,油隙的击穿过程中,流注头部的电场强度与净电荷密度会不断增加,形成自持放电;当流注到达绝缘纸板表面并在纸面积累电荷,将形成屏蔽层,导致流注的电场分布与电荷分布减弱,逐渐形成零电场区域 ...

气体成分对水中脉冲放电产生过氧化氢的影响

open access: yesGaoya dianqi, 2005
通过化学方法检测了水中脉冲放电产生的H2O2,通过拍摄照片研究流注长度的变化。实验发现,在分别通入氮气和氧气的情况下,随着气体流量和放电时间的增加,H2O2的浓度逐渐增加;在电极间距为5cm,所加电压为35kV时,通氮气比通氧气生成的H2O2多,通氮气时流注长度较通氧气时要长。在电极间距为3cm,所加电压为21kV时,通氧气比通氮气生成的H2O2多,而流注长度差异不大。

试验回路布置对变电站地网冲击特性测试的影响

open access: yesDianci bileiqi, 2020
开展地网冲击特性测试需搭建冲击放电回路,试验回路布置的差异会对地网冲击特性测试产生较大影响。在分析现有接地装置冲击试验系统构成的基础上,搭建试验回路对110 kV变电站地网进行了现场试验,研究了注流点对地网冲击特性的影响,并通过仿真计算研究了回流点对地网冲击特性的影响。试验结果表明,试验回路中注流点、回流点的选择会明显影响地网电位分布和电流的大小。在雷电冲击下地网高电位区域会集中在注流点附近,远离注流点的区域地网电位分布较均匀,注流点附近区域的地网散流变化大,远离注流点区域的地网散流较平均。仿真结果表明,
