This study is the first to directly visualize how salt crystals begin to grow and spread beneath a liquid meniscus during evaporation, according to the researchers. Using in situ X-ray microscopy, they were able to capture this hidden process in real time—a long-standing mystery in surface science and interfacial crystallization.
The work has implications for a wide range of applications, including desalination, mineral recovery, anti-fouling coatings, membrane technologies, and art preservation.
This work was carried out in part through the use of MIT.nano’s facilities!
