MOFs, hygroscopic hydrogels, carbon sorbents, and salt-loaded porous matrices can now capture substantial amounts of water from air. Several practical challenges remain, however: Many high-performance sorbents are made f

Metrics such as Unit Power Consumption (kWh/L), Specific Energy Consumption, Water Harvesting Rate, and Specific Water Production per mass of sorbent have beco

This review shifts the conversation toward a different and increasingly important application: ultrapure wat

Original Authors: Konstantinos Taliantzis and Kosmas Ellinas Original paper is accessible at: https://doi.org/10.1039/d5nr05114b Why surface patterning matters in atmospheric water collection Atmospheric water harvesting is not limited to sorbents such as MOFs, hydrogels, or hygroscopic salts. Another important pathway is passive atmospheric water collection, where water is collected directly from fog droplets or from dew formation on cooled surfaces. In these systems, the su
