Efficient Autonomous Dew Water Harvesting by Laser Micropatterning: Superhydrophilic and High Emissivity Robust Grooved Metallic Surfaces Enabling Filmwise Condensation and Radiative Cooling (Adv. Mater. 18/2025)

Abstract: Dew Water Harvesting by Laser Micropatterning A metallic surface micropatterned with a laser achieves self-cooling capacity when it faces the night sky thanks to its enhanced infrared emissivity, which triggers water condensation similar to natural dew on leaves. The patterned microgrooves promote condensation as a continuous film rather than dispersed droplets, enabling an efficient and autonomous harvesting of dew water. More details ban be found in article number 2419472 by Pablo Pou-Álvarez and co-workers.
