Rare 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 ...

Shuitu Baochi Xuebao, 2006 科尔沁沙地草地退化、沙漠化过程存在着疏林草地、沙质草场、半流动沙地和流动沙地等明显的逆行演替阶段，并且不同的阶段对应着适合本生境的典型群落类型，每一群落优势种的作用明显。草地退化过程中，原生地带性群落及演替早期群落物种丰富、多样性高．结构复杂，随着草地退化、沙漠化过程，群落组成物种数、科属减少．禾本科植物衰退，物种多样性降低，草地群落结构趋于简单、质量下降。在退化的各个阶段，一年生、二年生和旱生植物功能群在各个阶段始终保持着较高的优势地位．对群落生态功能的发挥和维持起着重要作用 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Periodontitis is a chronic infectious oral disease triggered by periodontopathogenic bacteria, resulting in the progressive inflammation and destruction of the tissues surrounding teeth. To achieve reprogramming of the infectious microenvironment for periodontitis therapy, a nanoformulation was proposed by loading polydopamine (PDA) with ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The growing concern over human health issues, driven by increasingly severe electromagnetic pollution from 5G communication, has made the urgent development of high‐performance electromagnetic wave (EMW) absorbing materials. Although carbide‐based materials are promising because of their conductive and polarization losses, existing single ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Chemically self‐charging aqueous zinc‐ion batteries (AZIBs) have emerged as promising candidates for energy storage technologies owing to their environmental autonomy and structural simplicity. Nonetheless, the self‐charging performance is significantly compromised by the limited potential difference between cathodes and oxygen, as well as the

Wildlife Letters, Volume 4, Issue 1, Page 23-31, March 2026.American badgers, a medium‐sized carnivore occurring in much of North America, are important predators in prairie landscapes though our understanding of their habitat use requirements in these areas is unclear. We used a multi‐scale approach to understand American badger habitat use at both local and landscape scales.
