In thermodynamic equilibrium, the contact angle is related by Young's equation to the
interfacial energies. Unfortunately, it is practically impossible to measure the equilibrium …

So far, scientists have successfully mimicked superhydrophobicity based on careful
observation and study of such surfaces found in nature. The key outcome is the fact that …

For a liquid droplet to slide down a solid planar surface, the surface usually has to be tilted
above a critical angle of approximately 10°. By contrast, droplets of nearly any liquid “slip” on …

Wetting phenomena are ubiquitous in nature and technology. A solid substrate exposed to
the environment is almost invariably covered by a layer of fluid material. In this review, the …

We discuss in this review how the roughness of a solid impacts its wettability. We see in
particular that both the apparent contact angle and the contact angle hysteresis can be …

Research into extreme water-repellent surfaces began many decades ago, although it was
only relatively recently that the term superhydrophobicity appeared in literature. Here we …

The wetting of rough surfaces remains a subject of active investigation by scientists. The
contact angle (CA) is a traditional parameter used to characterize the hydrophobicity/philicity …

The operation of a piezo inkjet printhead involves a chain of processes in many physical
domains at different length scales. The final goal is the formation of droplets of all kinds of …

This book enlightens readers on the basic surface properties and distance-dependent
intersurface forces one must understand to obtain even simple data from an atomic force …

Water condensation on surfaces is a ubiquitous phase-change process that plays a crucial
role in nature and across a range of industrial applications, including energy production …
