Toward Sustainable Separation and Recovery of Critical Metals From Discarded Industrial Perovskite Solar Modules

Advanced Science, EarlyView.
An architecture‐guided recycling process enables selective metal recovery from end‐of‐life perovskite solar modules by exploiting interfacial accessibility and calcination‐induced phase transformation. The process achieves >99.8% Pb removal, >99.7% In recovery, and >96.1% Cu recovery, while selectively retaining Sn in leaching residue.

A new insight into the NaCl-induced hot corrosion mechanism of TiN coatings at 500 degrees C

, 2020
The NaCl-induced hot corrosion behaviors of TiN coatings at 500 degrees C were investigated. The results showed that NaCl could accelerate hot corrosion of TiN coatings, but NaCl applying method has different effects on the failure of the coating.
