Gallium‐Doped α‐MnO2 Cathode for High‐Performance Aqueous Zinc‐Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Rechargeable aqueous zinc‐ion batteries (ZIBs) have received significant attention because of their high safety and low cost. MnO2 as a cathode material hampers the application of ZIBs due to its structural instability and dissolution during the operation of the battery.

Dizhen xuebao我国地震地电场观测时的漏电干扰问题会影响到观测质量和地震监测效能。针对这一实际问题，本文提出了点源干扰源定位方法。该方法首先建立地表点源对地电场观测影响模型，根据模型计算点源对地电场观测的干扰幅度，然后求解干扰源相对于中心电极的位置。将定位方法应用于高邮地震台和汉王地震台实际干扰源排查工作中，定位结果与实际干扰源位置基本一致，测区外干扰源定位误差小于2%，测区内干扰源定位误差小于20 m，并对影响计算误差的因素进行了分析。两个台站的实际应用表明 ...

A Mini Review of Scientific Designs of Dynamic Responsive Fluids in Battery Technologies
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Dynamic responsive fluids are emerging as transformative elements in the evolution of battery technologies, marking a pivotal shift from static passive designs toward systems that actively sense and adapt to their operating environments. By integrating dynamic responsive fluids, batteries can interact with both internal and external stimuli in

Dianci bileiqi, 2018 为提高±800 kV哈郑直流输电线路接地系统的技术经济性,在输电线路杆塔反击耐雷性能和人身安全分析的基础上,提出了取消人工接地体而采用基础独立接地所需的接地电阻与接触、跨步电位差的控制目标,对典型杆塔基础接地体的接地电阻和电位差进行了计算,获得了接地电阻和电位差与土壤电阻率的关系,据此提出了满足接地电阻和电位差目标的土壤电阻率范围。结果表明:不需要考虑接触和跨步电位差的野外地区,在西北少雷区,可采用基础独立接地的最大土壤电阻率可达1 700Ω·m以上,在非西北少雷区,最大土壤电阻率通常在1 000Ω ...

Dams in intrastate ethnic conflict: A comparison of Turkey and Ethiopia
World Water Policy, Volume 10, Issue 4, Page 1044-1065, November 2024.Abstract Why do dams exacerbate ethnic conflict in Turkey but not in Ethiopia? This paper analyzes the impacts of a growing push to develop water resources through hydroelectric dams, which promise clean energy, jobs, and economic opportunities. Yet dam building also causes environmental degradation, mass relocation, the flooding of historical sites ...
