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).
Emulsions occur either as end products or during the processing of products in a huge range of areas including the food, agrochemical, pharmaceuticals, paints and oil industries. As end products, emulsions allow to avoid organic solvent in processing hydrophobic coatings. Emulsion technology is a suitable approach to vehicle viscous phases. It is also a remarkable mean of targeting actives or capturing specific species. The range of applications of emulsions progresses and their manufacturing becomes more and more sophisticated. Besides this broad domain of technological interest, emulsions are raising a variety of fundamental questions at the frontier between physic and chem istry. Indeed, ...
Bio-nanotechnology is the key functional technology of the 21st century. It is a fusion of biology and nanotechnology based on the principles and chemical pathways of living organisms, and refers to the functional applications of biomolecules in nanotechnology. It encompasses the study, creation, and illumination of the connections between structural molecular biology, nutrition and nanotechnology, since the development of techniques of nanotechnology might be guided by studying the structure and function of the natural nano-molecules found in living cells. Biology offers a window into the most sophisticated collection of functional nanostructures that exists. This book is a comprehensive re...
Innovations of agri-food systems during the last 50 years have been guided by a globalized agro-industrial paradigm, which has contributed to climate change, degradation of natural resources, soil depletion, social inequalities, loss of biodiversity and various food-related health problems. Despite the increasing emphasis of food policies and research to address these issues with ecologically sustainable innovations, there are still no studies that explain how to utilize and integrate ecodesign practices in food products development in a world of finite resources. This book explains how to employ ecodesign in business models to address the economic, social, environmental, and nutritional pro...
This volume includes 11 contributions to the 23rd Conference of the European Colloid and Interface Society which took in Antalya, Turkey between September 6th and 11th, 2009. The contributions from leading scientists cover a broad spectrum of topics concerning• Self Assembly• Interfacial Phenomena• Colloidal Dispersions and Colloidal Stability• Polymer Solution, Gels and Phase Behaviour• Nanostructured Materials• Biomaterials and Medical AspectsDue to the increasing significance of Colloid and Interface Science for both scientific and technical applications where scientific principles also contribute to new technologies in fast improving Nanotechnology and Medical Science, this book will be an essential source of information with respect to recent developments and results related to this field.
This book takes an interface science approach to describe and understand the behavior of the dispersions we call emulsions, microemulsions and foams. The one thing all these dispersions have in common is the presence of surface-active species (surfactants) adsorbed at the interfaces between the two fluid phases that make up the emulsions, microemulsions or foams. The interfacial layers formed by the surfactants control most of the properties of the dispersions. The book describes the properties of interfacial layers, thin films and bulk fluids used in the elaboration of the various dispersions and it explains how such properties relate to the dispersion properties of these soft matter systems: structure, rheology and stability. These dispersion properties are far from being fully understood, in particular foam and emulsion stability. In discussing the state of the art of the current knowledge, the author draws interesting parallels between emulsions, microemulsions and foams that enlighten the interpretation of previous observations and point to a deeper understanding of the behavior of these materials in the future.
This first book devoted to this hot field of science covers materials with bimodal, trimodal and multimodal pore size, with an emphasis on the successful design, synthesis and characterization of all kinds of hierarchically porous materials using different synthesis strategies. It details formation mechanisms related to different synthesis strategies while also introducing natural phenomena of hierarchy and perspectives of hierarchical science in polymers, physics, engineering, biology and life science. Examples are given to illustrate how to design an optimal hierarchically porous material for specific applications ranging from catalysis and separation to biomedicine, photonics, and energy conversion and storage. With individual chapters written by leading experts, this is the authoritative treatment, serving as an essential reference for researchers and beginners alike.
Emulsions occur either as end products or during the processing of products in a huge range of areas including the food, agrochemical, pharmaceutical, paint and oil industries. Despite over one hundred years of research in the subject, however, a quantitative understanding of emulsions has been lacking. Modern Aspects of Emulsion Science presents a comprehensive description of both the scientific principles in the field and the very latest advances in research in this important area of surface and colloid science. Topics covered include emulsion formation, type, stability (creaming, flocculation, ripening, coalescence), monodisperse and gel emulsions, and applications. Emphasis has been plac...
L’accès à une alimentation de qualité pour tous reste un enjeu sociétal majeur. À travers des projets issus du concours ÉcoTrophélia, Écoconception et éco-innovation dans l’agroalimentaire présente les dispositifs pour écoconcevoir des produits alimentaires qui respectent les normes environnementales, sociales et nutritionnelles. Ces cas d’études incluent des exemples d’éco-innovations associant produits alimentaires et modèles d’affaires aux caractéristiques plus durables que ceux communément mis en oeuvre. Cet ouvrage offre des outils et des méthodes qui permettent de faire évoluer les pratiques et les modèles d’affaires des entreprises agroalimentaires.
