Solar Steam Generator with Divergent Microchannels for Highly Efficient and Salt‐Resistant Brine Evaporation (Adv. Mater. Technol. 18/2024)

Solar Steam Generator In article number 2400175, Sangmin Jeon and Jihun Choi develop a novel solar steam generator, featuring divergent microchannels, through directional freezing of a polypyrrole–cellulose nanofiber suspension in an inverted frustum mold. The microchannels, which extend from the bottom to the top and side surfaces with gradually increasing diameters, promote water transport to both surfaces, leading to highly efficient and salt-resistant brine evaporation.
