Advances in Contact Angle, Wettability and Adhesion
, 2019Microor nano-textured hydrophobic surfaces have attracted considerable interest due to their highly water-repellent property, and are called superhydrophobic.

Contact angle equilibrium: the intrinsic contact angle
Journal of Adhesion Science and Technology, 1992The conceptual and mathematical difficulties associated with contact angle equilibrium are reviewed and analyzed. The main discussion is centered around the theory of the intrinsic contact angle and its dependence on the three-phase mutual interactions in the vicinity of the contact line.

Physics of Fluids A: Fluid Dynamics, 1992
Young [Philos. Trans. (1805)] derived an equation for the contact angle between a liquid–gas interface and a solid boundary, but doubts have been raised about its validity. This issue is reexamined on the basis of a new integral equation for the interface [J. B. Keller and G. J. Merchant, J. Stat. Phys. 63, 1039 (1991)].

Contact Angle Hysteresis Explained
Langmuir, 2006A view of contact angle hysteresis from the perspectives of the three-phase contact line and of the kinetics of contact line motion is given. Arguments are made that advancing and receding are discrete events that have different activation energies. That hysteresis can be quantified as an activation energy by the changes in interfacial area is argued ...

Journal of Dentistry, 1987
Abstract Determination of contact angle is important to several areas of dentistry, denture retention being one. However, published reports attribute spurious significance to advancing and retreating angles, the distinction between the sources of which is not recognized.

Contact Angle Saturation in Electrowetting
The Journal of Physical Chemistry B, 2005Electrowetting is the phenomenon of contact angle decrease under the influence of an external voltage applied across the solid/liquid interface. Electrowetting offers an interesting possibility to enhance the wettability of hydrophobic materials without altering the chemical composition of the system and thus could be incorporated in various ...

Contact Angles of Pharmaceutical Powders
Journal of Pharmaceutical Sciences, 1977Contact angles of pharmaceutical powders were determined by measuring the maximum height of a drop of a saturated solution on a presaturated compact of the material. The results for a series of drugs are presented.

Mechanisms for contact angle hysteresis and advancing contact angles
Journal of Petroleum Science and Engineering, 1999Mixed-wet crude oil/brine/mineral systems typically show a large contact angle hysteresis between the water-receding angle during primary drainage and the water-advancing angle during imbibition. Also, the water-advancing angle may have values that range from 50° to 180°.

Equilibrium contact angle or the most-stable contact angle?
Advances in Colloid and Interface Science, 2014It is well-established that the equilibrium contact angle in a thermodynamic framework is an "unattainable" contact angle. Instead, the most-stable contact angle obtained from mechanical stimuli of the system is indeed experimentally accessible. Monitoring the susceptibility of a sessile drop to a mechanical stimulus enables to identify the most stable

CONTACT ANGLE MEASUREMENTS ON HARD CONTACT LENSES
Optometry and Vision Science, 1973The contact angle of water on three hard contact lens materials was determined by direct measurement. Aqua-Lens and Aqua-Cept materials had lower contact angles than conventional hard lens materials.
