Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Aqueous zinc batteries hold great promise for large‐scale energy storage, yet their practical application is hindered by dendrite growth and interfacial side reactions on the zinc anode. Inspired by the industrially mature chromate passivation technology, this work reports an in situ construction of a chromium‐rich passivation layer (Zn@Cr) on

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 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Li–O2 batteries garner widespread attention owing to their remarkable theoretical specific capacity. Nevertheless, the feasible implementation of the system is hindered by sluggish cathode reaction kinetics and poor anode stability. Herein, the carbon dots (CDs) with ‐OH, ‐NH2, and ‐COOH groups are synthesized and employed as electrolyte ...

Gongye shui chuli, 2014 为研究高频脉冲电源对循环水系统的阻垢机理,采用一套小型高频电磁循环水处理系统,以脉冲频率为变量,完成6 组阻垢实验,分析不同脉冲频率下钙离子溶度的变化趋势,并观察扫描电镜下相应的垢样微观结构.结果发现,在不同脉冲频率下,处理组的钙离子溶度变化相比空白组呈现高、低、接近这3 种趋势.高频电磁脉冲的阻垢机理:脉冲频率对水体的作用既阻碍结垢又促进结垢,当电磁频率与氢键共振频率接近时,阻碍结垢起主导作用;当电磁频率与杂质粒子共振频率接近时,促进结垢起主导作用,且两种作用一般同时存在.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...
