Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

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 ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...
