The fundamental side of this book covers general aspects of stability, interfacial adsorption mechanisms, interfacial rheology, direct measurements of surface forces and the bulk rheological properties of emulsions, and self-diffusion properties as measured by NMR. The applications side covers the fields of food, crude oil and pharmaceutical emulsions. A central topic in the study of food emulsions is the role played by proteins at the water/oil interface, their conformations, and the mechanism by which they can be replaced at the interface (competitive adsorption). The mechanisms underlying the resolution of water are of crucial importance in the study of water-in-crude-oil emulsions. The book therefore discusses the characterization of the stabilizing asphaltene fraction, the physiochemical properties of destabilizing surfactants, and the interplay between asphaltenes and waxes at the W/O interface. The structures of pharmaceutical emulsions and creams are characterized, as well as nonionic vesicle drug administration systems. Finally, fluorocarbon emulsions acting as blood substitutes are also discussed.

Practical scope of modern-day colloid science may be presented through a set of achievements and actual aims in preparation of novel materials and construction of novel technologies based on the foundation of knowledge on colloid systems. Yet many uncertainties pervade such field, ranging from the true potential of self-organising and self-assembling systems in the design of advanced material structures to numerous encounters over the question of practical viability between the tendencies to invest in knowledge on small-scale, molecular recognition processes and on spontaneous, large-scale mesoscopic formation phenomena. Albeit the existence of belief in advancement of knowledge on stereoscopic molecular recognition and molecular assembly manipulation that would eventually lead to perfect control inherent in the design of macroscopic structures, trial-and-error phenomena seem to permeate all relevant levels of organisation within practical colloid science approaches, from enzymatic, biomolecular recognition processes to the macroscopic design of novel functional outcomes. As genetic evolution teaches us, the major point of any design conductance is not elimination of inherent mistakes, but their productive acceptance, that is mutual coupling with development of improved and more richly organised contexts of knowledge. Within this perspective, inter-disciplinarity, that is constructive crossing of separate scientific areas of investigation, presents a necessary approach immanent in advancement of practical colloid science achievements in the coming era.

Colloidal systems are important across a range of industries, such as the food, pharmaceutical, agrochemical, cosmetics, polymer, paint and oil industries, and form the basis of a wide range of products (eg cosmetics & toiletries, processed foodstuffs and photographic film). A detailed understanding of their formation, control and application is required in those industries, yet many new graduate or postgraduate chemists or chemical engineers have little or no direct experience of colloids.

Based on lectures given at the highly successful Bristol Colloid Centre Spring School, "Colloid Science: Principles, Methods and Applications" provides a thorough introduction to colloid science for industrial chemists, technologists and engineers. Lectures are collated and presented in a coherent and logical text on practical colloid science.

The Comprehensive, Single-Source Reference on Multiple Emulsions
In theory, multiple emulsions have significant potential for breakthrough applications in food, agricultural, pharmaceutical, nutraceutical, and cosmetic industries in which they can facilitate the sustained release and transport of active material. However, in practice, multiple emulsions are thermodynamically unstable. This book presents recent findings that can help formulators understand how to enhance their stability. With chapters contributed by leading experts from around the world, it covers the definition and properties of multiple emulsions, their formation and stability, and potential applications, with an emphasis on medical and pharmaceutical applications. In one definitive resource, it presents recent findings and achievements in the field, including:
New theoretical approaches and modeling to characterize the transport mechanism
Droplet size reduction and increased shelf life stability through the use of polymeric amphiphiles and complex adducts
The use of new emulsification techniques to enhance the monodispersibility of the droplets
Potential applications in drug delivery systems where clinical studies have proven their efficacy
This is a core, hands-on reference for surface and colloid scientists, physical chemists, chemical engineers, soft materials scientists, food chemists, controlled release scientists, and pharmaceutical scientists in drug delivery applications, as well as for graduate students in these disciplines. The editor and contributors hope this logical consolidation of current information will further the understanding of multiple emulsions and lead to new, practical applications.

Molecular and Colloidal Electro-Optics presents cohesive coverage from internationally recognized experts on new approaches and developments in both theoretical and experimental areas of electro-optic science. It comprises a well-integrated yet multi-disciplinary treatment of fundamental principles, strategies, and applications of electro-optic techniques for the characterization of macromolecular, small-particle, and nanomolecular systems.

Following a historical review of post-war advances in electro-optics of disperse systems, the first part of the book focuses on the latest achievements in electro-optic theory, particularly low-frequency relaxation. It offers comparative discussions and experimental data to accompany different viewpoints on the origin of the low-frequency effects and multiple theoretical constructions. The second part highlights the unique advantage of using electro-optics as an alternative to conventional characterization and analysis of colloidal systems. Demonstrating the sensitivity of electro-optic methods to interparticle interactions, the book explains how these methods are used to analyze particle surface electric states, evaluate phase transitions, and determine physical properties.
