Webunderstanding of the coffee-stain calls for the perplex analysis of interfacial phenomena. The detailed experimental and theoretical analysis of the coffee-stain formation was undertaken first by Deegan et al. in Refs. 1–2. The authors of Refs 1–2 tested a wide range of experimental conditions WebStains produced by the evaporation of coffee spills In physics, a " coffee ring " is a pattern left by a puddle of particle-laden liquid after it evaporates. The phenomenon is named for the characteristic ring-like deposit along …
