We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee-ring effect." As a droplet evaporates, the edges dry faster than the center, pulling fluid—and suspended particles—outward. This creates a dense ring of material at the periphery of the droplet. It's a familiar sight to anyone who's spilled tea or coffee, but for scientists working on coatings and inks, this effect can be frustrating. In many applications, a uniform deposit is far more useful than a ring. /news/2025-07-coffee-saucer-patterns-graphene-oxide.html Nanophysics Nanomaterials Thu, 17 Jul 2025 08:25:04 EDT news671959492 A team of researchers report in the Proceedings of the National Academy of Sciences on a new graphene-based sensor design that, through machine learning, was able to develop a near-human sense of taste.
