From: The impact of surface chemistry on the performance of localized solar-driven evaporation system

Evaporation rates of HBN-HLA and HBN-HBA illuminated under different power density of ~3.2 kW/m2 (a) and ~14.3 kW/m2 (b).
The calculations of the difference between relative evaporation rate (ΔRr) are shown under the plots.
