Summary

This book aims to give an overview of the most recent advances in emulsion science. The basic principles of emulsion science, covering aspects of emulsions from their preparation to their destruction, are presented in close relation to both the fundamental physics and the applications of these materials. The book is intended to help engineers in formulating new materials by giving them an understanding of these basic principles, as well as serving as a reference book.
