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.

The goal of Interface Science and Composites is to facilitate the manufacture of technological materials with optimized properties on the basis of a comprehensive understanding of the molecular structure of interfaces and their resulting influence on composite materials processes. From the early development of composites of various natures, the optimization of the interface has been of major importance. While there are many reference books available on composites, few deal specifically with the science and mechanics of the interface of materials and composites. Further, many recent advances in composite interfaces are scattered across the literature and are here assembled in a readily accessible form, bringing together recent developments in the field, both from the materials science and mechanics perspective, in a single convenient volume. The central theme of the book is tailoring the interface science of composites to optimize the basic physical principles rather than on the use of materials and the mechanical performance and structural integrity of composites with enhanced strength/stiffness and fracture toughness (or specific fracture resistance). It also deals mainly with interfaces in advanced composites made from high-performance fibers, such as glass, carbon, aramid, and some inorganic fibers, and matrix materials encompassing polymers, carbon, metals/alloys, and ceramics. Includes chapter on the development of a nanolevel dispersion of graphene particles in a polymer matrix Focus on tailoring the interface science of composites to optimize the basic physical principles Covers mainly interfaces in advanced composites made from high performance fibers

Particles at Interfaces presents recent developments in this growing field and is devoted entirely to the subject of particle transport, deposition and structuring on boundary surfaces. The complex problems which have been studied include concentrated systems of polydisperse and non-spherical particles, bio-particles such as DNA fragments, proteins, viruses, bacteria, cells, polymers, etc. These complex structures undergo transformations under the action of surface forces. Particles at Interfaces provides readily accessible reference data and equations for estimating basic effects, and is mainly addressed to students and young scientists. Consequently, most approaches are of a phenomenological nature, enabling one to derive concrete expressions which describe the basic physics of the problem under consideration. To facilitate access to the information contained in the book most of the relevant formulae and results are compiled in Tables, accompanied with appropriate diagrams. The math is limited to the necessary minimum with emphasis on the physics of the phenomena, defining why they occur, what the kinetics of the processes and the practical implications are. Fill a substantial gap in the subject of particle transport, deposition and structuring on boundary surfaces Combines traditional theories of electrostatics, hydrodynamics and transport with new approaches Provides readily accessible reference data and equations for estimating basic effects

Sorbent Deformation discusses the theoretical and experimental study of the deformation of solid bodies during their ad- or absorptive interaction with gases or vapours. The book is the first monograph which deals with the problem of ad- and absorbent non-inertness, compiled from a 15-year study by the author on swelling or deformed ad- and absorptive systems. The results from the study are of practical and scientific value to engineers and scientists in the areas of physical chemistry, chemical engineering and environmental control. They could also be of interest to those looking to solve problems in such areas as forecasting, technological processing and fuel drying stimulation. · Provides novel, practical information on the behaviour of the systems used in environment control · Presents the derivation of the equation describing single- and multicomponent adsorption and absorption in swelling / deformed systems · Identifies the results of direct measurements on ad-and absorbent deformations (charcoals, clay minerals, organic cation substituted clay minerals, etc.) with a new high sensitivity method

Macromolecules in Solution and Brownian Relativity illustrates the recent picture of statistical physics of polymers and polymer solutions that emerges from some paradigms of contemporary science joint together. Among its principal aims are discussing the consequences of a novel self-diffusion theory, which benefits from an extension towards relativistic-like principles, and the generalization of usual concepts met in polymer science in terms of geometry alone. The monograph gives the whole fundamentals necessary to handle the view proposed, which is set in the final chapters. All the formers see about to provide the reader with a comprehensive treatation of the necessary fundamentals of classical, relativistic, quantum and statistical mechanics. Among the most important mechanical theories ever developed, a chapter on the Brownian movement and another on macromolecules prepare the ground that is specific to face universality and scaling behaviors in polymer solutions. The scope of the book is therefore two-fold: On the one hand, it wishes to involve the readers and scholars into a new research on polymer physics and chemistry. On the other, to get close chemical physicists and physical chemists to disciplines which, traditionally, are far from their direct fields of interest. Cross-disciplinarity Novelty Potentiality
