Abstract The paper surveys the variational thermodynamic approach, enabling defining and predicting equilibrium contact angles. The approach enables considering 1D, 2D and 3D contributions to the free energy of the sessile droplet. 3D components of free energy such as contributions due to external fields or heat release do not influence equilibrium contact angles. In the situation when 1D (line tension) contributions to the free energy are neglected the equilibrium contact angle depends only on…

The Possibility of Changing the Wettability of Material Surface by Adjusting Gravity
The advancing and receding contact angles on extremely low contact angle hysteresis surfaces under different gravities (1-8G) are measured and it is found that both of them decrease with the increase of the gravity.
A generalized examination of capillary force balance at contact line: On rough surfaces or in two-liquid systems.
The results confirm that solid-liquid interactions perpendicular to the interface have a significant influence on the lateral component of the capillary force exerted on the contact line and set up the generalized theoretical framework for the capilla force balance at the contactline.

It is shown that equilibrium contact angles of drops vary significantly depending on the vapour pressure in the ambient atmosphere, while there is a single, unique equilibrium contact angle in thin capillaries, and the static advancing contact angle of a drop depends on its volume, in agreement with experimental data.
Contact angles of rotating sessile droplets
Abstract The paper proposes a general framework allowing the analysis of wetting problems in the situation where a sessile drop is placed on a rotating substrate. Wetting of ideal, rough and
Line tension effect on contact angles: Axisymmetric and cylindrical systems with rough or heterogeneous solid surfaces
Abstract Equations for the apparent, intrinsic, and actual contact angles are presented, which account for the effect of line tension in axisymmetric and two-dimensional (cylindrical) systems with
A new wetting mechanism based upon triple contact line pinning.
A new model based upon the TCL pinning is developed to explain the different wetting properties of the Wenzel and Cassie models for hydrophilic and hydrophobic cases and predicts the macroscopic contact angle in a broader range accurately, which is consistent with the existing experimental findings.
Contact angle hysteresis on doubly periodic smooth rough surfaces in Wenzel's regime: The role of the contact line depinning mechanism.
The contact angle hysteresis, appearing when a liquid meniscus is in contact with doubly sinusoidal wavelike patterned surfaces in Wenzel's wetting regime, is reported on.

It is demonstrated that the contact angle hysteresis is inevitable on gradient surfaces.
Wetting of Composite Surfaces: When and Why Is the Area Far from The Triple Line Important?
Apparent contact angles are totally governed by the area of the solid surface adjacent to the triple (three-phase) line. However, apparent contact angles do not describe the wetting situation
Wetting under chemical equilibrium and nonequilibrium conditions
The thermodynamics of a solid-liquid-vapor system both under chemical equilibrium and nonequilibrium conditions, based on the model of Gibbs, is discussed. Under chemical equilibrium conditions, the

Understanding of contact angles for liquids on solids has improved in the last two decades and this progress is driven by advanced imaging techniques and improved methodologies in contact angle measurements, often in tandem with direct force measurements for liquid droplets in contact with solids.
