Wetting behaviour and wetting transitions of alkanes on aqueous surfaces

Advances in Colloid and Interface Science, 2009
The nature of the surface forces, acting in the wetting films of pentane, hexane and heptane on water and on aqueous NaCl solutions is discussed. It is shown that an important contribution to the surface forces originates from the low solubility of water in short-chain alkanes.

Wetting of nanopatterned surfaces: The hexagonal disk surface

The Journal of Chemical Physics, 2004
Metropolis Monte Carlo simulations are used to investigate the wetting of chemically nanopatterned surfaces, for the case of hexagonal disk patterns where liquid wishes to wet high-energy circular patches but not wet the background surface. We calculate the density profiles of saturated liquid adsorbed on a variety of such substrates, spanning the ...

Fundamentals and Applications of Surface Wetting

Langmuir
In an era defined by an insatiable thirst for sustainable energy solutions, responsible water management, and cutting-edge lab-on-a-chip diagnostics, surface wettability plays a pivotal role in these fields. The seamless integration of fundamental research and the following demonstration of applications on these groundbreaking technologies hinges on ...

Wetting of Surfaces Covered by Elastic Hairs

Langmuir, 2010
We study the wetting properties of elastic hairy surfaces. Neither our theory nor our experiments support the suggestion by Otten and Herminghaus [Langmuir 2004, 20, 2405-2408] that the interplay between wetting, capillary interactions, and elasticity is responsible for the hydrophobic behavior of the leaves of a Lady's Mantle.

Electro-(de)wetting on Superhydrophobic Surfaces

Langmuir, 2013
Usually, electrowetting on superhydrophobic surfaces (EWOSS) is generated by application of an alternating current signal and often leads to droplet impalement into the structuration. To avoid this phenomenon, superhydrophobic surfaces must show robustness to high pressure.

Forced wetting of a reactive surface

Advances in Colloid and Interface Science, 2012
The dynamic wetting of water on gelatin-coated poly(ethylene terephthalate) (GC-PET) has been investigated by forced wetting over a wide speed range and compared with earlier data obtained with unmodified PET. The results were analysed according to the molecular-kinetic theory of dynamic wetting (MKT).

Ice-Phobic Surfaces That Are Wet

ACS Nano, 2012
Ice formation on surfaces and structures produces damage and inefficiencies that negatively impact all manners of activities. Not surprisingly, for a long time, an unmet challenge has been to design materials capable of minimizing or even eliminating the formation of ice on the surface of the material. In recent years, there were significant efforts to

Wetting Phenomena on Structured Surfaces

Advanced Materials, 1999
Wetting phenomena on structured surfaces are reviewed. The interplay between the two-dimensional pattern of surface domains and the three-dimensional morphology of the wetting fluid is theoretically discussed. The results presented illustrate the novel morphological aspects in the wetting behavior.

Wetting of textured surfaces

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2002
We discuss quantitatively the wetting of a solid textured by a designed roughness. Both the hydrophilic and the hydrophobic case are described, together with possible implications for the wetting of porous materials.

Moon Surfaces, and Boundary Behaviour of Capillary Surfaces for Perfect Wetting and Non-Wetting

Proceedings of the London Mathematical Society, 1988
The existence of a class of capillary surfaces, corresponding to perfect wetting and perfect non-wetting on adjacent circular boundary arcs, in the absence of gravity, is proved. The surfaces are shown to achieve the prescribed (extremal) data strictly at interior points of the boundary arcs, and to be discontinuous at the juncture points.
