Laser Induced Coffee?Ring Structure through Solid?Liquid Transition for Color Printing (Small 6/2023)

Coffee-Ring Structures In article number 2205696, Jianfeng Yan and co-workers propose a strategy of laser induced transient solid-liquid transition to fabricate coffee-ring structures. Through modulating the state metal from solid liquid phase using ultrafast pulse train, controllable fabrication structures is achieved. The structure exhibit tunable color, which can be used for color printing.
