Influence of Alkaline Earth Barium on the Microstructure, Corrosion Behavior, and Cytocompatibility of Biodegradable Zinc

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Biodegradable Zn‐based alloys are promising candidates for temporary implants, yet excessive Zn2+ release during degradation may induce cytotoxicity and adverse tissue responses. In this study, Zn‐xBa alloys (x = 0.1 wt%, 0.5 wt%, 1.0 wt% and 3.0 wt%) were developed to achieve controlled corrosion behaviors with improved biocompatibility.

Unveiling Temperature‐Dependent Corrosion Behaviors of FeNiCrMoCBY Amorphous Alloy Coatings In Spent‐Fuel Storage Environments

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT A comparative study was performed to elucidate the temperature‐dependent corrosion kinetics and the semiconductor/structural characteristics of the passive film formed on Fe40Ni7Cr17Mo12C13B9Y2 (at%) amorphous alloy coatings. The results indicate that increasing temperature accelerates the corrosion kinetics of the coating.

Interfacial Dipole Engineering With Taurine‐Modified SnO2 Electron Transport Layer for Efficient and Stable Perovskite Solar Cells

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Organic‐inorganic metal halide perovskite solar cells (PSCs) are promising for photovoltaics due to their excellent optoelectronic properties. However, achieving high efficiency and stability remains challenging, mainly due to defects and energy losses at the electron transport layer (ETL)/perovskite interface.
