Phosphate Recovery from Arsenic-Laden Groundwater Treatment Sludge

Abstract In this work, we investigated phosphate (P) recovery via calcium phosphate (CaP) precipitation from P-rich solutions produced synthetically and derived from arsenic (As)-laden groundwater treatment sludges. We systematically altered key variables in synthetic experiments...

Direct Observation of Tantalum Nitride Photoelectrode Degradation by Environmental Transmission Electron Microscopy

Abstract Stability under realistic operating conditions remains a critical challenge for photoelectrochemical (PEC) materials in solar fuel production, where photocorrosion often leads to rapid performance degradation. In particular, the formation of insulating amorphous TaOx/Ta(...
