, 2014 磁雷诺数和流体力学中的雷诺数一样, 是一个无量纲参数。它是用于判断磁通（参见注释1）在磁流体（参见注释2）中是处于冻结还是扩散的一个参数。利用磁通冻结的概念，可以较直观地理解用常规方法产生电磁脉冲的原理。在现代社会中，电磁脉冲有着相当广泛的应用，这里我们通过分析电磁脉冲武器的工作原理，来看看它和磁流体力学中一些相关知识的关系。 以往的经验表明，现代化战争大部分都以电子战的形式拉开序幕。而电磁脉冲武器无疑是电子战武器库中的一个重要成员。在1999年北约轰炸南联盟的战争中，美国第一次使用了电磁脉冲炸弹 ...

Electrically Switchable Altermagnetism in Monolayer MoCl3
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Altermagnets intertwine spin‐split bands with vanishing net magnetization, offering great potential for high‐density, stray‐field‐free spintronic devices. However, their development is hindered by both material scarcity and difficulties in external control due to their intrinsic symmetry protection.

, 1979 磁流体力学旋转流问题中一般假设流体输运系数为常数。用磁流体力学方法处理电弧放电问题时,经常假设弧柱內外的输运系数分别为两个不同的常数,并取弧柱外介质的电导率为零。在气态裂变反应堆、核火箭及重元素的同位素分离器中,广泛采用交叉电磁场的方法产生等离子体的高速旋转流动。文献[8,9]研究了薄层放电的电磁驱动装置,用多对极实验得到一定的分离效果。可以认为 ...

Research Progress and Prospect of Single‐Atom Materials in Tumor Catalytic Therapy
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tumor catalytic therapy (TCT), an emerging therapeutic modality, exerts specific cytotoxic effects on tumor cells by catalyzing endogenous substances within the tumor microenvironment (TME)—including hydrogen peroxide (H2O2), glucose, and glutathione—to generate reactive oxygen species (ROS) or deplete protective biomolecules.

Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The low energy density of sodium‐ion batteries (SIBs) remains a major barrier to their large‐scale deployment. Alloy‐based anodes represent a promising class of materials owing to their high specific capacity and low operating potential for sodium storage. However, their practical application is hindered by severe volume expansion upon cycling.
