Description

Written by the founder of the field, this practice-oriented guide summarizes the author's breakthrough research results and their applications in chemical technology.
The book adopts an entirely novel approach, describing the physical chemistry of structure formation and materials synthesis under dynamic conditions. It begins by developing the general theory in the first two chapters with as little mathematics as necessary and substantiated by experimental results in each case. The following chapters deal with the fundamental aspects of rheology, vibrorheology, and superfluidity of structured dispersed systems within the framework of physicochemical dynamics, while the final chapter exemplifies the technological applications of the developed methodology using real-life problems of materials science and chemical engineering.
The authoritative guide to physicochemical dynamics.
