Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

500/220kV同塔四回输电线路接地开关开合感应电压—感应电流能力研究
Gaoya dianqi, 2013 同塔多回输电线路有效解决了电网建设与输电走廊紧缺之间的矛盾,但对接地开关提出了严苛的要求。笔者以500 kV祯宝甲乙线与220 kV东莆甲乙线同塔四回架设为例,对感应电压和感应电流进行了理论分析,采用电磁暂态仿真程序（ATP-EMTP）计算了两种不同运行工况下,停运线路的感应电压和感应电流。发现计算结果超过了标准规定的接地开关能够开合的B类感应电压、电流的要求。依据计算结果对500 kV东莞站采用的220 kV JW6-252/J50型接地开关进行了开合超B类感应电压、电流的试验。在开断电磁感应电压2 ...

Gaoya dianqi, 2008 笔者介绍了用于高压直流电流测量的电子式直流电流互感器,针对其中决定测量结果的关键部分-分流器及一次联结导体,重点进行了热效应分析。理论分析得出:分流器自身和一次联结导体在直流大电流下都有热效应,而在高压直流线上谐波和阶跃响应产生的集肤效应还将导致不可忽视的附加热效应;一次联结导体的交、直流热效应共同作用将对分流器的测量产生影响。实验证明鼠笼结构的分流器可有效地抑制谐波电流的热效应,电子式直流电流互感器的热稳定性试验不宜用工频交流等效,只有采用实际直流才能真实可靠的反映其热稳定性能。
