WebContact angle goniometry (literally "angle measurement") as a means to characterize liquid-solid interactions took a major step forward in the 1960's with the development of the NRL (Naval Research Laboratory) goniometer by William Zisman. The NRL-type goniometer is a precision instrument well suited for laboratory investigations. WebAug 26, 2024 · Software connected to the camera is used to identify and calculate the contact angle of the droplet on the substrate. There are two ways to set up a sessile drop test. The first is known as the “general type” (also known as “horizontal type”). In this case, the camera is pointed horizontally, parallel to the substrate, to view the droplet.

WebThe contact angle is a measure of the ability of a liquid to wet the surface of a solid. The shape that a drop takes on a surface depends on the surface tension of the fluid and the nature of the surface. At the boundary … WebOscilla is a word applied in Latin usage to small figures, most commonly masks or faces, which were hung up as offerings to various deities, either for propitiation or expiation, and in connection with festivals and other ceremonies.
