Scalable Solar Evaporator In the Research Article by Ji-Hyun Jang and co-workers (DOI: 10.1002/adma.202517285), a bandgap-engineered CuMnCrO4 spinel oxide is introduced as a high-performance photothermal absorber for solar desalination. Multi-cation design broadens solar absorption, enabling excellent evaporation rates. Integrated into an inverted U-shaped architecture, the system achieves continuous water transport, salt resistance, and exceptional stability under saline, extreme pH, and contaminated conditions, demonstrating scalable and durable freshwater production.
