Researchers from Tokyo Metropolitan University have discovered a new way of controlling the drying patterns formed by re-crystallizing salt. They found that the coffee ring effect can be used to pin the edge of drying droplets, creating a range of different geometric patterns. The same principles may be applied to understand and improve the adhesion of printer ink to surfaces and the manufacture of film-based devices.
