A Topology‐Guided Design Strategy for Polymerized Naphthoquinone Cathodes in Rechargeable Aluminium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Rechargeable aluminium‐ion batteries (RAIBs) are promising candidates for sustainable energy storage owing to their low cost, safety, and resource abundance. However, the lack of durable cathode materials restricts their development. Here, we propose a topology‐guided design strategy by synthesizing three thioether‐bridged naphthoquinone ...

Template‐Assisted Construction of Atomically Dispersed Fe‐N‐C Catalysts With Dense Fe‐N4C Sites for Enhanced Oxygen Reduction Reaction

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Atomically dispersed iron–nitrogen–carbon (Fe‐N‐C) catalysts have emerged as promising alternatives for oxygen reduction reaction (ORR) owing to their highly atomic utilization. However, maintaining both Fe atomic dispersion and dense Fe‐Nx sites (typically below 2 wt%) in Fe‐N‐C catalysts is still a key challenge.

Acid‐Etched Co‐Vacancy‐Tunable CoFeP/N,P‐Codoped Carbon Nanocages for Highly Efficient Alkaline Water Electrolysis

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

Non‐Precious Metals Enhance Hydrogen Evolution in COF/Cd0.9Cu0.1S S‐Scheme Heterojunctions: KPFM Reveals Charge Transfer Pathways

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Photocatalytic hydrogen production from water splitting is a promising strategy for sustainable and clean energy generation. However, the design of low‐cost, highly active photocatalysts remains a critical challenge. In this study, covalent organic frameworks (COFs) were loaded onto the surface of Cd0.9Cu0.1S to fabricate COF/Cd0.9Cu0.1S ...

Phosphorus‐Doping Drives the Formation of a Pt‐Skin@PtFe Alloy Catalyst With Modulated d‐Band Center for Oxygen Reduction

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

Band Edge Reorganization via Symmetry Constraints in Covalent Bonding Heterojunctions Boosts Photocatalytic Metronidazole Degradation

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The covalent bonds at heterojunction interfaces enable more efficient charge carrier separation than traditional weakly coupled heterojunctions, with enhanced photocatalytic performance for organic wastewater purification. The interfacial covalent bonds drive energy band reorganization, rendering the conventional independent band edge ...

From Microstructure to Macroscopic Performance: A Comprehensive Study on Low‐K Oxide‐Doped BNT–LST–NN Ceramics for Energy Storage

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Dielectric ceramics are popular for energy storage materials because of their rapid charge–discharge characteristics, whereas their low energy density and efficiency hinder their miniaturization and integration. In this work, the energy storage performance is significantly enhanced through introducing Al2O3 and TiO2 into the 0.425(Bi0.5Na0.5 ...

Skin barrier, phenotypic and genotypic characterisation of autosomal recessive ichthyosis in TGM1‐deficient Jack Russell Terriers and response to topical ceramide

open access: yesVeterinary Dermatology, Volume 35, Issue 6, Page 617-625, December 2024.
Background – Autosomal recessive ichthyosis leads to structural or biochemical changes that impair skin barrier function. Hypothesis/Objectives – To assess (1) the phenotype and genotype in a litter of Jack Russell Terriers with autosomal recessive congenital ichthyosis (ARCI), and (2) the defective skin barrier and determine if a topical ceramide can ...

带电测试法对MOA测量数据的影响

open access: yesDianci bileiqi, 2005
测量交流泄漏电流及其阻性分量是带电测试MOA的主要方法。在条件允许情况下,也可借助红外测温手段。评价MOA的运行状况时,应充分考虑带电测试MOA的泄漏电流、红外测温及常规停电试验之间的内在联系,结合三者试验数据做出正确评价,也可采用横向和纵向测量结果比较法来评价。

燃料电池膜电极透气性的测试方法及测试池和测试装置

open access: yes, 2011
本发明公开了一种燃料电池膜电极的透气性测试方法及测试池和测试装置。本发明可以测试膜电极在实际运行条件下膜电极的透气量。将膜电极组装在试验测试池中,试验测试池的一侧设有气体的进出口通道,而另一侧则形成测试通道;在试验测试池的两侧分别通入被测气体和载气,并将其载气侧的气体出口通入到气相色谱中,通过气相色谱测试载气中被测气体的含量,从而计算膜电极的透气率。膜电极的透气率测试装置主要由试验测试池和透气率测试系统组成。试验测试池由两块具有气体进口和出口的平板夹具和相应的密封材料组成。本发明提出了一种准确 ...
