Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...

Gaoya dianqi, 2006 组合波信号发生器（CWG）主要用于浪涌保护器或电子设备电磁兼容试验,要求在虚拟阻抗Z为2Ω的情况下,输出1.2/50μs开路电压波或8/20μs短路电流波。基于电路微分方程的方法对CWG等效电路进行数学计算,导出相应的数学关系,给出一套计算图表。对电路参数计算结果进行电路仿真,并将计算结果应用于实际CWG电路设计。同CWG标准参数要求比对,仿真结果最大偏差小于6%;实际设计的CWG参数最大偏差小于8%。结果表明,针对CWG电路参数的计算采用的方法是正确的,计算结果可以应用于CWG设计中电路参数的选取。

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...
