Du Noüy ring method - Wikipedia
网页In surface science, the du Noüy ring method is a technique for measuring the surface tension of a liquid. The method involves slowly lifting a ring, often made of platinum, from the surface of a liquid.
Du Nouy Ring Method - an overview | ScienceDirect Topics
网页Learn about the du Nouy ring method, a technique for measuring surface tension or interfacial tension by pulling a ring through a liquid interface. Find chapters and articles from books and journals on this topic.
Surface tension measurement by Du Noüy ring method
网页2020年8月18日 · Du Noüy method utilizes the interaction of a platinum ring with the surface of the liquid. The ring is submerged below the interface by moving the stage where the liquid container is placed. After immersion, the stage is gradually lowered, and the ring pulls up the meniscus of the liquid.

Du Noüy Ring Method - Vocab, Definition, and Must Know Facts
网页The Du Noüy Ring Method was developed by French scientist Pierre Du Noüy in the early 20th century as an improvement over earlier techniques for measuring surface tension. In this method, a platinum or other non-wetting ring is submerged in the liquid and then lifted, with the force needed to detach it being measured to calculate surface tension.
网页Surface tension by the ring method (Du Nouy method) In a second series of experiments repeat the above but start with pure water: Theory and evaluation. A molecule in a liquid is subject to forces exerted by all mole-cules surrounding it; pressure p is isotropic.

网页2.1. The Du Noüy ring method In the Du Noüy ring apparatus, a metallic (usually gold or platinum) ring is slowly lifted from the surface of a liquid. The ring is designed to have a very thin circular profile at one side (the one that is immersed in the liquid), like a knife blade. In this way, the liquid adheres to the
