      The dynamics of the Rayleigh-Taylor instability of a two-dimensional thin liquid film placed on the underside of a planar substrate subjected to either normal or tangential harmonic forcing is investigated here in the framework of a set of long-wave evolution equations accounting for inertial effects derived earlier by Bestehorn, Han, and Oron [“Nonlinear pattern formation in thin liquid.   Theory of the Hamaker constant.

Johnston Consultants Bureau • New York and London. Combination of G A with G el at various values of h results in the total energy G T –distance curve illustrated in Figure This presentation forms the basis of the theory of colloid stability due to Deryaguin–Landau–Verwey–Overbeek (DLVO theory) [5, 6].The G T –h curve shows two minima and one maximum: a shallow minimum (of the order of few kT) units at large distances of separation.

The first two volumes cover the role of surface forces, while the third looks at colloid stability and its application in pharmacy. Volume 4 deals with applications in personal care and cosmetics, while the last two volumes cover colloids in agrochemicals and in paints and coatings.

In this review, the research of the author in the field of colloidal systems is summarized. The factors influencing colloidal stability are systematized and analyzed. Examples are presented to illustrate the practical utilization of the theory of stability of colloids and thin films.

"The author is a well-known scientist in this field with a long experience in colloid science." (Henkel KGaA, Dusseldorf, Germany) "Dr. Tadros is well-known in the field of colloid science.

High quality can be expected." (University of Bayreuth, Germany) "Professor Tadros is a well-known expert on the topic. with theory the equilibrium thickness of films of this type decreases comparatively rapidly as the pressure rises.

These films are designated primary films. As the electro-lyte concentration rises, these primary films lose their stability, and their thickness, in parts, drops to a value of 5—10 nm.

Overbeek., with the collaboration of K. van Nes. The most impressive achievement of the theory of surface forces has been its successful solution of the classical problem of colloid stability.

The combination of long-range electrostatic and molecular forces provided the basis for a quantitative explanation of the stability of lyophobic colloids and the role played by electrolytes in their.

Colloids and Surfaces A: Physicochemical and Engineering Aspects, DOI: /fa Sukumar Pati, S.K. Som, Suman Chakraborty. Combined influences of electrostatic component of disjoining pressure and interfacial slip on thin film evaporation in nanopores. We use a newly developed set of interface conditions to revisit the problem of an evaporating thin liquid film.

In particular, instead of the conventional Hertz–Knudsen–Langmuir equation for the evaporation mass flux, we impose a more general equation expressing the balance of configurational momentum. A system of equations for the dynamics of a general three-dimensional thin film subject to van der Waals forces, surface tension, and surfactants was derived in Part I of this work [M.

This book presents an account of the stability of lyophobic colloids and suspensions and develops a quantitative theory on the subject.

Major topics consist of the theory of a single double layer (with considerations of the distribution of the electric charge and the free energy of a double layer system); the interaction of two parallel flat plates (including the potential energy via free.

An epoch in the development of the physical chemistry of colloids and surfaces is associated with his name. Derjaguin became famous in scientific circles for his work on the stability of colloids and thin films of liquids which is now known as the DLVO theory, after the initials of its authors: Derjaguin, Landau, Verwey, and Overbeek.

A general survey is given on the role that interparticular attraction forces play in the aggregative stability of colloidally dispersed systems. Special attention is paid to the disjoining pressure acting between interlayers.

The importance of recent results obtained by the author using the so-called flow ultramicroscope method is emphasized as these data allow the interpretation of the.

The nature of colloidal particles. To begin, you need to recall two important definitions: a phase is defined as a region of matter in which the composition and physical properties are uniform. Thus ice and liquid water, although two forms of the single substance H 2 O, constitute two separate phases within a heterogeneous mixture.; A solution is a homogeneous mixture of two or more substances.In book: Colloid Stability: The Role of Surface Forces - Part I, Volume 1, pp - Theory Of Stability Of Colloids And Thin Films.

Article. it is shown that the microscopic thin-film.The dynamics of an evaporating wetting liquid film in the presence of dissolved surfactant is investigated. The solid substrate is planar and is subjected to heating. The liquid–vapor interface is a two-dimensional continuum characterized by specific adsorption, interfacial viscosity, and surface tension, which depend on the surfactant subsurface concentration and temperature.
