Interaction of colloidal particles

The result is so lengthy that it is not even written out in the original paper [A. G. DeRocco and W. G. Hoover, "On the interaction of colloidal particles," Proc. Natl. Acad. Sci., USA, 46, 1057-1065 (I960)]. It consists of three expressions of the same form one is evaluated at d as written in function Ksp( bld+fjd+a. The two other terms are this same function but evaluated with d replaced everywhere with (d + a), and the resulting function Ksp(x d + a) multiplied by (—2) and this same function yet again but evaluated with d replaced everywhere with (d + 2a), the resulting function Ksp(x d + 2a)...

Some years later (about 1939) the problem of the interaction of colloidal particles was again investigated independently... 

In Part I the principles were discusseicl on which the interaction of colloidal particles may be understood, and by, way of application the case of the interaction of two parallel flat plates was dealt with in Part II. Starting from this case it was possible to form a picture of the behaviour of colloidal particles and to come to an understanding of such fundamental properties as stability, flocculation value and the rule of Schulze and Hardy. 

For the main part this book gives an.account of our own work on the interaction of colloidal particles. It has not been written, however, on the assumption that the whole of the relevant literature is known to the reader. Accordingly we have added a number of chapters which may serve as an introduction to the main problem of the book. These chapters contain, for instance, a brief survey of some aspects of lyophobic colloids, a concise summary of the theory of the double layer, and a short introduction to the subject of Van der Waals— London forces.

Abstract. Onsager s paper on the effect of shape on the interaction of colloidal particles is seminal in many ways. I shall focus on two aspects it is (to my knowledge) the earliest classical density functional theory, and it demonstrates the possibility of ordering transitions driven by entropy... 

In Chapter 6, the interaction of colloidal particles by charge regulation was introduced, but its treatment requires use of the concepts developed in Chapter 11 and in this chapter. We will show here the results of a rather recent study (Chan et al. 2006). 

In the ease when the size of one of the partieles tends to infinity (ai/ 2 1)> which corresponds to interactions of colloid particles with a eharged macroseopic sphere (electrode), the force is given by the Lorenz equation...

When two colloidal particles come near to each other the above-mentioned inconsistencies would become serious The influence of interaction of colloidal particles is however treated separately in Ch. VI and VIII.
