This book gives an overview of the most recent advances in emulsion science, from the preparation to the destruction of these materials. This book is intended for a large audience, from undergraduate students to senior scientists. A progressive and didactic approach is proposed for that purpose. The concepts presented should provide a useful guidance for formulating and controlling the lifetime of emulsion at laboratory and industrial scales. For easy comprehension, the text is illustrated by more than 70 figures. This book is a new edition of the one published in the series 'Springer Tracts in Modern Physics (vol. 181)'. The main difference is a more didactic approach which will allow the non-specialist reader to capture the essential concepts. We shall also incorporate the very last research results (solid-stabilized emulsions, metastability) and novel applications (Biotechnology).
