Bioinspired hydrogel pattern enhances atmospheric water harvesting via directional droplet steering par Frédéric PELASCINI | 27 Jan 2024 | Actualités Bioinspired hydrogel pattern enhances atmospheric water harvesting via directional droplet steering The water in the air originates from both natural and forced evaporation, with condensation being the final and crucial step in water harvesting. Condensation involves nucleation, growth, and shedding of water droplets, which are then collected. phys.org
