“Coffee rings” of different forms and sizes can be specifically “synthesized” as Z. Lin and co-workers report in their Communication on p. 512. Polymer solutions are confined in a space between a curved surface and a flat substrate. By using different geometrically curved surfaces, the controlled evaporation of the solution leads to self-assembly and the formation of higher-ordred structures over a large area.
