Interactions and pattern formation in a macroscopic magnetocapillary SALR system of mermaid cereal

A Hooshanginejad, JW Barotta, V Spradlin… - Nature …, 2024 - nature.com
When particles are deposited at a fluid interface they tend to aggregate by capillary
attraction to minimize the overall potential energy of the system. In this work, we embed …
