Available in PDF, EPUB and Kindle. Book excerpt: A dispersion is a system of unmixable phases in which one phase is continuous and at least one is finely distributed. Examples are found in many industrial applications, including emulsions, suspensions, foams, and geld. The control of their flow characteristics - rheology - is essential in their preparation, long-term physical stability and application. Filling the need for a practical, up-to-date book connecting the stability/instability of the dispersion to its rheological behavior, this title aids in understanding the principles of rheology and the techniques that can be applied. From the contents: * General Introduction * Interparticle Interactions and Their Combination * Principles of Viscoelastic Behavior * Rheology of Suspensions * Rheology of Emulsions * Rheology of Modifiers, Thickeners, and Gels * Use of Rheological Measurements for Assessment and Prediction of the Long-Term Physical Stability of Formulations (Creaming and Sedimentation)

Download or read book Colloidal Dispersions written by William Bailey Russel and published by Cambridge University Press. This book was released on 1991 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the physical side of colloidal science from the individual forces acting between particles smaller than a micrometer that are suspended in a liquid, through the resulting equilibrium and dynamic properties. A variety of internal forces both attractive and repulsive act in conjunction with Brownian motion and the balance between them all decides the phase behaviour. On top of this various external fields, such as gravity or electromagnetic fields, diffusion and non-Newtonian rheology produce complex effects, each of which is of important scientific and technological interest. The authors aim to impart a sound, quantitative understanding based on fundamental theory and experiments with well-characterised model systems. This broad grasp of the fundamentals lends insight and helps to develop the intuitive sense needed to isolate essential features of the technological problems and design critical experiments. The main prerequisites for understanding the book are basic fluid mechanics, statistical mechanics and electromagnetism, though self contained reviews of each subject are provided at appropriate points. Some facility with differential equations is also necessary. Exercises are included at the end of each chapter, making the work suitable as a textbook for graduate courses in chemical engineering or applied mathematics. It will also be useful as a reference for individuals in academia or industry undertaking research in colloid science.
Download or read book A Brief Introduction to Dispersion Relations written by José Antonio Oller and published by Springer. This book was released on 2019-03-22 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text offers a brief introduction to the dispersion relations as an approach to calculate S-matrix elements, a formalism that allows one to take advantage of the analytical structure of scattering amplitudes following the basic principles of unitarity and causality. First, the case of two-body scattering is considered and then its contribution to other processes through final-state interactions is discussed. For two-body scattering amplitudes, the general expression for a partial-wave amplitude is derived in the approximation where the crossed channel dynamics is neglected. This is taken as the starting point for many interesting nonperturbative applications, both in the light and heavy quark sector. Subsequently crossed channel dynamics is introduced within the equations for calculating the partial-wave amplitudes. Some applications based on methods that treat crossed-channel dynamics perturbatively are discussed too. The last part of this introductory treatment is dedicated to the further impact of scattering amplitudes on a variety of processes through final-state interactions. Several possible approaches are discussed such as the Muskhelishvili-Omnes dispersive integral equations and other closed formulae. These different formalisms are then applied in particular to the study of resonances presenting a number of challenging properties. The book ends with a chapter illustrating the use of dispersion relations in the nuclear medium for the evaluation of the energy density in nuclear matter.

Download or read book Solid Liquid Dispersions written by T. F. Tadros and published by Academic Press. This book was released on 1987-02-11 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid-liquid dispersions, also known as suspensions, are widely used in industry. Both aqueous and non-aqueous suspensions are used in paints, dyestuffs, inks, cosmetics, detergents, and pharmaceuticals. More recently, non-aqueous dispersions of magnetic oxides have attracted considerable attention as a result of their applications in the electronics industry. FROM THE PREFACE: Solid/liquid dispersions, both of the aqueous and nonaqueous type, find applications in many industrial preparations, of which the following may be worth mentioning: paints, dye stuffs, pigments, paper coatings, printing inks, cosmetics, ceramics, pharmaceuticals and pesticides. More recently nonaqueous dispersions of magnetic oxides have attracted considerable attention because of their applications in the electronic industry. The control of the properties of such systems is crucial both in their preparation, their long-term stability and in their subsequent application. Some of the parameters which control such properties are: particle size and shape distribution, interparticle interaction forces, and volume fraction of the dispersed phase. Understanding the basic principles involved in the preparation of solid/liquid dispersions and control of the interparticle interacting forces is, therefore, crucial both from a fundamental and applied point of view. Owing to the widespread use of solid/liquid dispersions in many industrial applications, a residential school was held at Bristol University during 1986 to fulfil some of the above requirements. The scientific content of the course was organized by he Editor and the residential school was sponsored by the Royal Society of Chemistry of Great Britain. This residential school was held to lay the basis of understanding of the colloid and interface science phenomena involved in the preparation of solid/liquid dispersions, their stabilization and destabilization and control of their bulk properties. The lecture contents were planned to cover a wide range of topics and these form the basis of the present book, which would be useful to graduate, research and industrial chemists. The book starts with an Introductory Chapter giving an outline of the contents of the book and the various themes that are covered. Chapter 2 deals with the preparation of solid/liquid dispersions with some emphais on the stabilization of such dispersions. Both aqueous and nonaqueous dispersions are discussed and the two main procedures used, namely condensation and dispersion methods, are described. This is followed by two chapters (3 and 4) on the structure of the solid/liquid interface and the electrical double layer and stability of dispersions in which double layer repulsion and van der Waals attraction are the main contributions. A section is also devoted in Chapter 4 on the kinetic aspects of coagulation and the expermimental methods used for determination of stability. Chapters 5 and 6 deal with the adsorption of surfactants and macromolecules, which are key factors in understanding how dispersions can be stabilized or flocculated by such molecules. With polymers, particular attention was given to the conformation of the molecule at the solid/liquid interface. The stability of solid/liquid dispersions in the presence of polymers (usually referred to as steric stabilization) is described in Chapter 7. This is then followed by a chapter on flocculation by polymers and polyelectrolytes (Chapter 8). The properties of concentrated dispersions, in particular their structure, are given in Chapter 9, in which an attempt is also made to relate the microscopic to the macroscopic properties. Chapter 10 deals with the rheology of colloid dispersions and the experimental techniques used for measurement of the viscoelastic properties. The following chapter (11) deals with settling of suspensions and prevention of formation of dilatant sediments. The theories of settling of dilute and concentrated suspensions are described and this is followed by the various procedures used for prevention of formation of dilatant sediments. Chapter 12 deals with a specific topic, namely the application of spectroscopic pKa probes for the determination of interfacial electrostatic potential. The last Chapter (13) deals with the practical methods that may be applied for assessment of the properties of suspension. Thus, the book, which has been produced as a result of the residual school on solid/liquid dispersions, is by no means a comprehensive text on the subject. The topics have been carefully chosen to cover the basic principles involved in the preparation of solid/liquid dispersions and the control of their properties. The book should, therefore, provide a useful text for readers involved with solid/liquid dispersions and their applications. Several useful references are given which should be consulted for more detailed information. would like to thank all the contributors for their care and cooperation in preparing the various chapters, which made my editing job fairly easy. I would like to thank the Royal Society of Chemistry, in particular Miss Lorraine Hart for organizing ghe adminstrative side of the Course and her help during the residential school. I would also like to thank Bristol University for hosting the residential school, and Mrs. Jean Proctor (Bristol University) and Mrs. Irene Gallacher (ICI) for their help in the organization of the residential school at Bristol. Last, but not least, I would like to thank my wife and children for coping with me during several weekends to write my contributions and editing the text. From the Reviews: "...Each chapter is written by a well known authority in the field and the exposition of the subject matter is particularly clear....It is a pleasure to see a book so well written and produced and I am sure that it will be an invaluable addition to the reading lists for graduate, research and industral chemists."

Download or read book Emulsions Foams and Suspensions written by Laurier L. Schramm and published by John Wiley & Sons. This book was released on 2006-05-12 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now colloid science books have either been theoretical, or focused on specific types of dispersion, or on specific applications. This then is the first book to provide an integrated introduction to the nature, formation and occurrence, stability, propagation, and uses of the most common types of colloidal dispersion in the process-related industries. The primary focus is on the applications of the principles, paying attention to practical processes and problems. This is done both as part of the treatment of the fundamentals, where appropriate, and also in the separate sections devoted to specific kinds of industries. Throughout, the treatment is integrated, with the principles of colloid and interface science common to each dispersion type presented for each major physical property class, followed by separate treatments of features unique to emulsions, foams, or suspensions. The first half of the book introduces the fundamental principles, introducing readers to suspension formation and stability, characterization, and flow properties, emphasizing practical aspects throughout. The following chapters discuss a wide range of industrial applications and examples, serving to emphasize the different methodologies that have been successfully applied. Overall, the book shows how to approach making emulsions, foams, and suspensions with different useful properties, how to propagate them, and how to prevent their formation or destabilize them if necessary. The author assumes no prior knowledge of colloid chemistry and, with its glossary of key terms, complete cross-referencing and indexing, this is a must-have for graduate and professional scientists and engineers who may encounter or use emulsions, foams, or suspensions, or combinations thereof, whether in process design, industrial production, or in related R&D fields.
