Contact angle and hne tension dependence on the curvature of the three-phase contact region has been analysed. It has been found that curvature effects can be neglected when the drop radius is larger than the thickness of the contact regron evcept for smalt contact angles. The contact angle 8 is rel

the intrinsic contact angle u i that a liquid drop makes with An approximate theory for calculating the line tension in a an ideal solid surface (2, 8) solid-liquid-fluid system is presented and demonstrated for a solid-liquid-vapor system. The line tension is shown to depend on the contact angle. C
Generally, the effect of line tension on equilibrium contact angles is considered in the modified Young equation. However, the modified Young equation is valid only for capillary systems with a horizontal solid surface. In this paper, a general Young equation is derived for a sessile drop in contact
