Fog Harvesting System: Cactus‐Inspired Conical Spines with Oriented Microbarbs for Efficient Fog Harvesting (Adv. Mater. Technol. 12/2019)

A cactus-inspired fog collection system integrated into conical spines with oriented micro-barbs and super-hydrophilic substrate is reported by Lelun Jiang and co-workers in article number 1900727. The conical spine with micro-barbs could significantly speed up the directional transport of drops and dramatically increase the fog collection efficiency.
