From coffee rings to saucer patterns—how graphene oxide's surface chemistry shapes evaporating droplet deposits
An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee-ring effect." As a ...
