Beschreibung:

Capillarity: Unconstrained Interfaces.- Capillarity and Gravity.- Hysteresis and Elasticity of Triple Lines.- Wetting and Long-Range Forces b.- Hydrodynamics of Interfaces -- Thin Films, Waves, and Ripples.- Dynamics of the Triple Line.- Dewetting.- Surfactants.- Special Interfaces.- Transport Phenomena.
The study of capillarity is in the midst of a veritable explosion. Hence the temptation to write a new book, aiming at an audience of
students. What is offered here is not a comprehensive review of the
latest research but rather a compendium of principles.
How does one turn a hydrophilic surface into one that is hydrophobic,
and vice versa? We will describe a few solutions. Some rely on
chemical treatments, such as coating a surface with a molecular layer.
Others are based on physics, for instance by controlling the roughness
of a surface. We will also examine the dynamics of wetting. Drops that
spread spontaneously do so at a rate that slows down with time. They
can be tricked into covering large areas by spreading them suddenly.
We will describe a few of the many facets of their dynamical
properties.
Special additives are required for water to foam. Foams are desirable
in a shampoo but can be a nightmare in a dishwasher detergent.
Antifoam agents have been developed and are well known, but how do
they work? It is also possible to generate bubbles and foams without
special additives, for example in pure and viscous liquids such as
glycerin, molten glass, and polymers. As we will see, the laws of
draining and bursting then turn out to be quite different from the
conventional ones.
This book will enable the reader to understand in simple terms such
questions that affect every day life -- questions that also come up
during in industry. The aim is to view systems that often prove quite
complex in a way that isolates a particular physical phenomenon, often
avoiding descriptions requiring advanced numerical techniques will
oftentimes in favor of qualitative arguments. This strategy may at
times jeopardize scientific rigor, but it makes it possible to grasp
things efficiently and to invent novel situations.
