Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Weakening the electrostatic attraction between Mg2+ ions and H− ions in MgH2 is vital for improving the kinetic performance of MgH2 for hydrogen storage. Herein, a multivalent microenvironment is synergistically created by Mn and Mg2Ni to break the stable structure of MgH2, enabling rapid and stable de/hydrogenation performance.
