sessile drop method

sessile drop method

[′ses·əl ¦dräp ‚meth·əd]
(fluid mechanics)
A method of measuring surface tension in which the depth and mass of a drop resting on a surface that it does not wet are measured; from this, the shape of the drop and, in turn, the surface tension are determined.

The water contact angle on the Bare-Mg and M-Mg was determined by a drop shape analyser using the sessile drop method with 2 [micro]L DI [H.sub.2]O.
Static contact angles were determined using the sessile drop method on a contact angle measurement apparatus (Powereach, JC2000D, China).
The contact angles between SBS-modified asphalt and distilled water, glycerol, and formamide were detected by the sessile drop method. Based on surface energy theory, the surface free energy and cohesive power of the SBS-modified asphalts were calculated.
The values of contact angles were determined using the dynamic sessile drop method with a goniometer-Rame-Hart Instrument Co model 250.
In vitro wettability is measured by different techniques: the sessile drop method, captive bubble or Whilhelmy Plate.
The contact angle measurements used to evaluate the surface wettability of PPT were performed by the sessile drop method were carried out using Kruss Easy Drop system (DSA20).
The static WCAs were measured at least 3 times using the sessile drop method by dispersing 5 [micro]L drops of deionized water onto the sample surface.
The contact angle was measured by the Sessile drop method, where the angle is measured between the base line (the line of touch of the surface) and the tangent on the drop curve in the point where solid, liquid and air phase meat.
(1993) determined that the sessile drop method gave the lowest contact angles and was the least reproducible when compared to the Wilhelmy balance and tilted plate methods.
[15] found that the application of DC could improve the wettability of molten Bi on Cu substrate using a DC-coupled sessile drop method, and current polarity did not give rise to significant difference on the wettability.
Contact angles (CAs) were measured between 5 [micro]L deionized water droplets and the nanostructured surface, using a drop shape analysis system (DSA 100, Kruss, Germany) with the sessile drop method.
Newmann Triangle: The Neumann triangle or sessile drop method is very similar to the pendant drop method, consisting of the study of the profile of a drop of one liquid resting on a flat plate surrounded by another liquid of smaller density (in the case of the determination of interfacial tension) or by air (in the case of determination of surface tension) at mechanical equilibrium.
