Is contact angle a cause or an effect? – A cautionary tale [PDF]
E3S Web of Conferences, 2020 The most influential parameter on the behavior of two-component flow in porous media is “wettability”. When wettability is being characterized, the most frequently used parameter is the “contact angle”.

Contact angle hysteresis and pinning at periodic defects in statics [PDF]
Physical Review E, 2014 This article deals with the theoretical prediction of the wetting hysteresis on nonideal solid surfaces in terms of the surface heterogeneity parameters. The spatially periodical chemical heterogeneity is considered. We propose precise definitions for both the advancing and the receding contact angles for the Wilhelmy plate geometry.

Static Electrification by Nonwetting Liquids. Contact Charging and Contact Angles
Langmuir, 1995 A glass slide hydrophobized with dimethyldichlorosilane appears to be electrostatically charged when a nonwetting liquid recedes from its surface. The surface charge has negative polarity. The density of the charge which arises on retraction from water is 10 -4 C/m 2 . The half-life of the charge on the surface in air is 0.5 h.

Precise Static Contact Angle Measurements Using Pythagolas Rule
Adhesion and Interface, 2014 Pythagolas rule was used for investigation of static contact angle in particular figures. Static contact angle measurement was important to evaluate the wettability between solid and liquid. Optimum measurement method and standardization of calculation for static contact angle were investigated for practical application. Optimum diameter of droplet for
