Foundations of Colloid Science, Volume 1Liquid suspension systems are the basic ingredients of paints, detergents, biological cells, and countless other systems of scientific and technological importance. This book presents the fundamental physical and chemical concepts necessary to the understanding of these systems and of colloid science in general. New ideas are introduced carefully and formulae are developed in full, with exercises to help the reader throughout. The frequent references to the many applications of colloid science will be especially helpful to beginning research scientists and people in industry, medicine and agriculture who often find their training in this area inadequate. Integrating developments from the time of colloid science's infancy forty years ago to its present state as a rigorous discipline, this intelligently assembled work elucidates a remarkable range of concepts, techniques, and behaviors. |

the stress : Y ( t ) = | J ( t - t ) ( 1 ' ) dt ( 2 . 4 . 6 ) where § = dS / dt and J ( t ) is called
the creep compliance . A knowledge of either G ( t ) , m ( t ) or J ( t ) can be used
to predict the effect of some imposed shear stress , provided it is not too large ...
