Exploring the potential of MXene-based advanced solar-absorber in improving the performance and efficiency of a solar-desalination unit for brackish water purification

Brackish water desalination using solar still (SS) is a low-cost sustainable solution to global water scarcity, but this technology suffers from low yield and efficiency. The judicious amalgamation of highly conductive materials with superior solar absorption behavior is one of the most effective ap...
