Book Description
Colloids are submicron particles that are ubiquitous in nature (milk, clay, blood) and industrial products (paints, drilling fluids, food). In recent decades it has become clear that adding depletants such as polymers or small colloids to colloidal dispersions allows one to tune the interactions between the colloids and in this way control the stability, structure and rheological properties of colloidal dispersions. This book offers a concise introduction to the fundamentals of depletion effects and their influence on the phase behavior of colloidal dispersions. Throughout the book, conceptual explanations are accompanied by experimental and computer simulation results. From the review by Kurt Binder: "They have succeeded in writing a monograph that is a very well balanced compromise between a very pedagogic introduction, suitable for students and other newcomers, and reviews of the advanced research trends in the field. Thus each chapter contains many and up to date references, but in the initial sections of the chapters, there are suggested exercises which will help the interested reader to recapitulate the main points of the treatment and to deepen his understanding of the subject. Only elementary knowledge of statistical thermodynamics is needed as a background for understanding the derivations presented in this book; thus this text is suitable also for advanced teaching purposes, useful of courses which deal with the physics for soft condensed matter. There does not yet exist any other book with a similar scope..... The readability of this book is furthermore enhanced by a list of symbols, and index of keywords, and last not least by a large number of figures, including many pedagogic sketches which were specifically prepared for this book. Thus, this book promises to be very useful for students and related applied sciences alike." Eur. Phys. J. E (2015) 38: 73

Book Description
The main thread-line connecting the different parts of this dissertation is various non-double layer interactions present in the colloidal system. The first chapter is a general introduction to the double layer and non-double layer interactions. In chapter 2 and 3, the double layer and hydration interactions have been coupled into a single set of equations because both are dependent on the polarization of the water molecules. The coupled equations involve the electric fields generated by the surface charge and surface dipoles, as well as the field due to the neighboring dipoles in water. The obtained equations were employed to explain the restabilization observed experimentally at large ionic strengths for colloidal particles on which protein molecules were adsorbed. In chapter 4, a general expression for the force generated between the two charged plates immersed in an electrolyte solution containing relatively small charged particles was derived based on Langmuir's approach. For charged plates immersed in a solution of an electrolyte and charged small particles, the effects of particle charge, particle charge sign, particle size and volume fraction of the particles on the force acting between the two plates were examined. In chapter 5, a cell model was proposed to examine the behavior of a dispersion of large particles immersed in an electrolyte solution containing small particles. chapter 6, two-dimensional Poisson-Boltzmann equation was solved to calculate the double layer interactions between two plates grafted polyelectrolyte. In chapter 7, a lower dielectric constant in the polymer adsorption layer is suggested The hairy adsorption layer can have a long range effect on the repulsive double layer interactions. In chapter 8, the bridging force induced by polyelectrolyte was investigated by using a self-consistent-field approach which takes into account the van der Waals interactions between the segments of the polyelectrolyte molecules and the plates, as well as the electrostatic and volume exclusion interactions. A positive contribution to the force between two plates is generated by the van der Waals interactions between the segments and the plates.

Book Description
Colloid and Interface Science in Pharmaceutical Research and Development describes the role of colloid and surface chemistry in the pharmaceutical sciences. It gives a detailed account of colloid theory, and explains physicochemical properties of the colloidal-pharmaceutical systems, and the methods for their measurement. The book starts with fundamentals in Part I, covering fundamental aspects of colloid and interface sciences as applied to pharmaceutical sciences and thus should be suitable for teaching. Parts II and III treat applications and measurements, and they explains the application of these properties and their influence and use for the development of new drugs. - Provides a clear description of the fundamentals of colloid and interface science relevant to drug research and development - Explains the physicochemical/colloidal basis of pharmaceutical science - Lists modern experimental characterization techniques, provides analytical equations and explanations on analyzing the experimental data - Describes the most advanced techniques, AFM (Atomic Force Microscopy), SFA (Surface Force Apparatus) in detail

Book Description
From blood to milk, pumice to gelatine, most scientists interact with colloids on a daily basis without any real knowledge of their nature. Building on the success of the first edition, Colloids and Interfaces with Surfactants and Polymers Second Edition is a user-friendly, non-technical introduction to colloids and interfaces. Includes: Many practical examples of colloid and interface science An enhanced section on fluorescence microscopy, a widely used technique in biological systems for the optical imaging of cellular structures A new section on phenomenology (the principle of time/temperature superposition), which enables the experimentalist to extend the frequency range of their rheological instruments New information on sedimentation and strategies for the control of sedimentation, which is critical in many dispersions of commercial importance Fresh treatments of traditional theoretical topics like the electrical double-layer, colloidal interactions, wetting behavior and light scattering, as well as more recent advances in polymer science, statistical mechanics and the use of neutrons In-depth discussions of widely used techniques with mathematics used in a straight-forward way so quantitative descriptions of colloid and interface properties can be derived Colloids and Interfaces with Surfactants and Polymers Second Edition explains all the fundamental concepts of colloids and interfaces as well as detailing some of the more advanced aspects which might be useful in specific applications. Intended for undergraduate and graduate courses in colloids and soft materials, the book is also relevant to those in the chemical, coatings, cosmetics, ceramics, food, pharmaceutical and oil industries.

Book Description
Food Colloids: Interactions, Microstructure and Processing describes the principles and practice underlying the formulation of food emulsions, dispersions, gels, and foams. Emphasis is on understanding how the functional properties of biopolymers and surfactants determine the texture and shelf-life of multiphase food materials. This book provides essential new findings by experts in the field on specific topics including: the interfacial rheological properties of proteins; the use of microscopy and image analysis to probe structure and phase transitions; the control of colloidal stability during thermal and mechanical processing; the interactions of proteins with polysaccharides and emulsifiers; the incorporation of neutraceuticals into food colloids; and the consumer perception of taste and texture. Food Colloids: Interactions, Microstructure and Processing provides a link between current research on the fundamental physical chemistry of colloidal systems and the requirements of the food technologist to use modern colloid science in new product formulation. It is suitable for postgraduates and researchers, both in industry and academia.
