Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Infrared (IR) stealth is crucial for improving the survivability of equipment. The growing demand for service in marine environments poses new challenges to the composition and structural design of existing IR stealth coatings. This study first investigates the effects of NaCl/water vapor corrosion on the IR stealth performance of GH3536 and a

Anode‐Free Alkali Metal Batteries Under Extreme Temperatures
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Anode‐free alkali metal batteries (AFAMBs) have attracted considerable interest as promising candidates for next‐generation energy storage systems, owing to their high energy density and simplified manufacturability. Extending their reversible and stable operation to low‐temperature (LT) and high‐temperature (HT) environments is crucial for ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Light‐activated gas sensors hold significant potential in environmental monitoring and smart Internet of Things (IoT) owing to their advantage in room temperature operation. Nevertheless, due to a narrow light absorption range, high photocarrier recombination rate, and weak redox activity of the sensing material, the performance enhancement of
