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 Cleaning products, candles, cribs, and cosmetics are just a few of the common household items that emit formaldehyde, a colorless, odorless chemical that, when present in the air at levels higher than 0.1 parts per million, has been found to be a risk to human health. /news/2025-07-polymer-coating-life-mxene-based.html Nanomaterials Fri, 11 Jul 2025 14:00:01 EDT news671278376 A new coating for glass developed by Rice University researchers and collaborators could help reduce energy bills, especially during the cold season, by preventing heat-loss from leaky windows.
