Sound waves create mist that can act like 'plant sunscreen'

Phys · · 741 words · By RMIT University

Researchers at RMIT University have developed a method using high-frequency sound waves to create a fine mist of covalent organic frameworks (COFs) for coating fragile surfaces. The process allows for the application of UV-blocking layers on living plant leaves and other sensitive materials at room temperature without causing damage.
