Encapsulation of Bi2S3 Within Multifunctional Sulfurized Polyacrylonitrile Matrix Enables High‐Performance Wide‐Temperature Sodium/Potassium‐Ion Batteries Through Solid–Solid Conversion
Rare 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.Fuyu Xiao, Xinye Li, Yiyi Wang, Fenqiang Luo, Lihui Chen, Zhenyang Huang, Xin Chen, Renpin Liu, Xiaochuan Chen, Lingxing Zeng, Qingrong Qian, Qinghua Chen +11 morewiley +1 more source永磁直驱风机通过MMC-HVDC并网的故障穿越策略
Gaoya dianqi, 2017 当受端交流电网发生严重短路故障,经柔性直流并网的风电场必须降低出力,使直流输电系统的直流电压保持在安全范围内。针对永磁直驱风机经MMC-HVDC并网系统,提出一种提升其故障穿越能力的控制策略。该策略结合降低风电场交流电压和降低风机输出有功电流2种方式,可以实现风电场侧有功功率的快速降低。同时,为了在故障时限制永磁直驱风机直流链电压的增长,在风机中引入直流电压偏差控制。仿真结果表明:主网发生对称和不对称故障时,MMC直流电压和永磁同步风机直流链电压均可维持稳定,系统可以实现故障穿越。于洋, 徐谦, 杨升峰, 徐政doaj Atomically Dispersed Platinum Sites Immobilized on NiFe LDH by Controlling Localized Amorphization for Efficient Alkaline Electrocatalytic Hydrogen Evolution

Gaoya dianqi, 2017 高压开关电动操动机构的电气制动技术虽然是一项重要的应用技术,但是未得到足够的重视。因此,文中系统阐述了电气制动技术的工作原理及其技术特点,总结了工程应用中出现的常见问题与排查方法,利用Lab VIEW软件对样机的制动参数进行了测试。经分析得出:采用能耗制动,将电动机变为他励发电机,产生的制动能量使电动机构在0.3 s以内完成停车。根据电机回路电源类别选择不同的制动方式:永磁直流电动机为直流电源时,采用单电阻制动方式;串励电动机为单相交流电源,采用双电阻制动方式。在相同的制动回路中 ...陈旭, 刘新军, 李东涛, 牧骞, 黄婷, 闫嫱, 赵聪 +6 moredoaj Boosting Thermoelectric Properties of BiSbSe3 Through Ag‐Induced Interstitial Occupancy and Multi‐Phase Microstructure
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT
Te‐free BiSbSe3 is a promising medium‐temperature thermoelectric (TE) material owing to its cost‐effectiveness and intrinsically low lattice thermal conductivity. However, its comparatively low electrical conductivity has severely hindered the optimization of TE performance.Xiaowei Shi, Quanwei Jiang, Yu Yan, Xinghui Wang, Peipei Liu, Huijun Kang, Enyu Guo, Zongning Chen, Rongchun Chen, Jun Wang, Tongmin Wang +10 morewiley +1 more source高压断路器直线电机操动机构的动态特性分析
