Interaction of colloidal

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)... 

The product of these reactions is a brown powder, but it is doubtful whether that prepared by the interaction of colloidal silver and chlorine-water is a definite chemical compound, since successive ehlorinations of colloidal silver produce a series of homogeneous mixtures of silver and silver chloride.9... 

Photohalides.—The rose-red to purple-brown mixtures of silver sub-chloride and silver chloride are called by Carey Lea photochlorides. They are formed by the interaction of colloidal silver and a suspension of silver chloride by the action of organic reducers and of light on silver chloride10 and by the electrolytic chlorination of sheet silver,11 The... 

Studies of the interaction of colloidal metal particles with macroelectrodes are essential for an understanding of properties such as the redox potential of the nanometallic particles in the presence of a particular environment. This information will be useful in extending the conventional electrochemical treatment to colloidal systems.

Colloidal particles interact strongly with the fluid, but the individual particles have some structural integrity, so they cannot be said to dissolve homogeneously. The colloidal mixture behaves so distinctively because of the latge surface area of interaction between the particles and water or air. The ions at the boundary interact with the ions and molecules of both phases. This is true at any surface or phase boundary, but the interaction of colloidal phases is large because their surface areas are so large. A 1-mm sand particle has a surface area/mass ratio of about 0.002 m2g-1 a -fixa clay particle, 2 m2g 1 and a 1-nm particle, 2000 m2g 1. 

The close interaction of colloid and surface science with molecular physics and a number of theoretical disciplines has determined its role in the development of natural sciences as a whole. The discovery of the nature of, and the further investigation of Brownian motion, the development of direct... 

Svedberg s primary focus as a physical chemist was the field of colloid chemistry. Colloids are mixtures of very small particles that when dispersed in solvents are not dissolved, but are held in suspension by various actions of the solvent. Svedberg and his collaborators studied the interaction of colloid suspensions with light and their sedimentation processes. These studies showed that the gas laws could be applied to colloidal systems. Svedberg s Ph.D. thesis on the diffusion of platinum colloidal particles elicited a response from Albert Einstein, since it supported Einstein s theory concerning the Brownian motions of colloidal particles.

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.
