Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

IMC-PID Controller Design for Linear Systems with Parametric Uncertainties [PDF]
, 2015 控制系统控制品质的好坏直接决定了生产品质和效益，而工业过程控制中 百分之九十以上的控制器仍是PID控制器。于是，PID控制器参数整定一直以 来是工程应用和理论研究的核心问题之一。众多PID整定法中，IMC-PID控制 器参数整定方法脱颖而出，越来越广受工业控制过程的青睐。原因在于，基 于IMC的PID控制器对模型要求较低，甚至在高阶低阶、不稳定或非线性等情 况下，它都能获得有效的控制品质。而且IMC-PID仅有一个整定参数，该参数 调整与系统动态品质和鲁棒性的关系比较明确，从而无需繁杂的整定就可以使 ...

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Thermally driven hydrogenation of CO2 to light olefins (C2=–C4=) using metal oxide‐zeolite tandem catalysts is an effective strategy for achieving carbon neutrality. However, progress in this area is constrained by zeolite pore transport limitations, acid‐site inactivation, and surface carbon poisoning.
