Encapsulation of Bi2S3 Within Multifunctional Sulfurized Polyacrylonitrile Matrix Enables High‐Performance Wide‐Temperature Sodium/Potassium‐Ion Batteries Through Solid–Solid Conversion

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT With high theoretical capacity and low cost, bismuth sulfide (Bi2S3) demonstrates considerable potential as an anode for sodium/potassium‐ion batteries (SIBs/PIBs). Unfortunately, significant volume variation, low electrical conductivity, and dissolution of polysulfides drastically weaken their intrinsic merits.

Structural Modification and Deformable Design of Electrospun Sn@C Nanofiber Anodes Through Oxide Doping for Flexible Lithium‐Ion Batteries

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Size‐controllable Sn nanoparticles are designed in this work via oxide doping to be uniformly embedded into flexible N‐doped carbon nanofibers, in which the agglomeration and migration of Sn are effectively restrained due to the suppressive effect of selected oxides, including SiO2, TiO2, and ZnO. Benefiting from unique merits of the embedment

Synergistic Engineering of Amorphous Cathode and Hybrid Electrolyte Toward Stable High‐Voltage Aqueous Zn‐Ion Batteries

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

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

Rare 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 ...

基于地统计学的土壤团聚体空间变异研究进展

, 2019
团聚体是土壤基本结构单元,犹如生物体的细胞,深刻影响着土壤肥力和植物生长,并在土壤抗蚀性、土壤修复、全球碳汇效应等方面起着重要作用。过去研究多关注于土壤团聚体的微观形成过程与稳定机制。由于土壤特性、自然要素、人为活动等多因素共同驱动,团聚体的微观尺度分析并不能完全理解团聚体在生态系统中的作用与功能;同时,团聚体结构和稳定性具有高度空间异质性,传统的经典统计学方法难以反映真实状态下团聚体的空间格局,使得其研究方法逐渐过渡到地统计学。本文综述国内外基于GIS和地统计学的土壤团聚体空间变异性的研究现状 ...
