Liquid Metal Liesegang Rings
In article number 2209392, Qian Wang, Jing Liu, and co‐workers investigate the Liesegang rings phenomenon induced by gallium‐based liquid metal (LM) on gold film systems. The mechanisms are attributed to the reaction‐diffusion and spreading‐limiting processes of the LM on gold film, over which chemical reactions occur simultaneously with the spatially recurrent crystallization...
Room temperature liquid metals (LM) such as gallium (Ga) own the potential to react with specific materials which would incubate new application categories. Here, diverse self‐organized ring patterns due to nonequilibrium reaction‐diffusion and spreading‐limitation of Ga‐based LM clusters on gold (Au) film are reported, among which diffusion is the controlling step and the self‐limiting oxide layer...
