Structured Fluids by Thomas A. Witten Pdf

Over the last thirty years, the study of liquids containing polymers, surfactants, or colloidal particles has developed from a loose assembly of facts into a coherent discipline with substantial predictive power. These liquids expand our conception of what condensed matter can do. Such structured-fluid phenomena dominate the physical environment within living cells. This book teaches how to think of these fluids from a unified point of view, showing the far-reaching effects of thermal fluctuations in producing forces and motions. Keeping mathematics to a minimum, the book seeks the simplest explanations that account for the distinctive scaling properties of these fluids. An example is the growth of viscosity of a polymer solution as the cube of the molecular weight of the constituent polymers. Another is the hydrodynamic radius of a colloidal aggregate, which remains comparable to its geometrical radius even though the density of particles in the aggregate becomes arbitrarily small. The book aims for a simplicity, unity and depth not found in previous treatments. The text is supplemented by numerous figures, tables and problems to aid the student.

A Structured Fluids Approach to Canopy Flow by Mark N. Silbert Pdf

The 'classical' turbulence approach to the flow of air in a vegetative canopy is reviewed. Three separate 'classical' theories are described. A comparison is made between experimentally measured canopy flows and a velocity function derived from the theory of structured continua. The agreement between theory and observations is good, but not unexpected, due to seven degrees of freedom in the fitted velocity profile. Proposals for future study for a more rigorous test of the theory are discussed.

Liquid Detergents by Kuo-Yann Lai Pdf

A bestseller in its first edition, Liquid Detergents, Second Edition captures the most significant advances since 1996, maintaining its reputation as a first-stop reference in all fundamental theories, practical applications, and manufacturing aspects of liquid detergents. Featuring new material and updates in every chapter, the book expands its coverage of emulsions to include nanoemulsions, adds new data to elucidate the rheology of current commercial detergent raw materials as compared to finished products, and offers a more complete theoretical treatment of the aggregation in non-aqueous solvents. The book now covers all rheology modifiers and thickeners for detergent applications, antibacterial and sensorial light-duty liquid products, color/fabric care and wrinkle reduction in heavy-duty liquid detergents, and household cleaning wipes in specialty liquid household surface cleaners. Rewriting the chapters on the latest improvements and growing benefits in fabric softeners, liquid hand soaps and body washes, and shampoos and conditioners, the latter contains extensive summaries of patents for various new products and technologies. The final chapter, dedicated to the manufacturing of liquid detergents, offers a discussion on continuous vs. batch processes and micro-contamination. The most comprehensive guide of its kind, Liquid Detergents, Second Edition, is a balanced and practical reference that will continue to inspire students, researchers, chemists, and product developers in detergent industry, surfactant science and industrial chemistry.

Electrorheological (ER) and magnetorheological (MR) fluids, which can be transformed from the liquid state into the solid state in milliseconds by applying an electric or a magnetic field, are smart fluids having the potential to revolutionize several industrial sectors. The Seventh International Conference on Electrorheological Fluids and Magnetorheological Suspensions took place at a time when some MR and ER applications were beginning to appear on the market, making a notable impact on industries. Scientists and engineers in multidisciplinary areas came together to explore the state-of-the-art technology and identify thrust areas to be focused on. This volume of proceedings collects contributions from most leading experts in the field. It reviews the most recent MR and ER applications, discusses the materials technology, explores the basic science research on ER and MR fluids, and examines the novel properties of these fluids. It provides the most up-to-date and probably the best information about the area. It can serve as a stimulating and valuable reference for research workers and students in materials science, condensed matter physics, engineering, and chemistry.

Structure and Functional Properties of Colloidal Systems by Roque Hidalgo-Alvarez Pdf

Integrating fundamental research with the technical applications of this rapidly evolving field, Structure and Functional Properties of Colloidal Systems clearly presents the connections between structure and functional aspects in colloid and interface science. It explores the physical fundamentals of colloid science, new developments of synthesis and conditioning, and many possible applications. Theory Divided into three parts, the book begins with a discussion of the theoretical side of colloid dynamics. It then transitions to dynamically arrested states and capillary forces in colloidal systems at fluid interfaces. Structure Covering the structural aspects of different colloidal systems, the second section examines electric double layers and effective interactions as well as the structure of extremely bimodal suspensions and filaments made up of microsized magnetic particles. The contributors analyze the role played by the attractive interaction, confinement, and external fields on the structure of colloidal systems. They also discuss structural aspects in food emulsions and the rheological properties of structured fluids. Functional Materials The last part focuses on examples of functional colloids. These include polymer colloids, protein-functionalized colloidal particles, magnetic particles, metallic nanoparticles, micro- and nanogels, responsive microgels, colloidal photonic crystals, microfluidics, gel-glass dispersed liquid crystals (GDLCs) devices, and nanoemulsions. This volume provides a sound understanding of the link between the structure and functional properties in two- and three-dimensional colloidal systems. It describes techniques to functionalize colloids, characterization methods, the physical fundamentals of structure formation, diffusion dynamics, transport properties in equilibrium, the physical fundamentals of nonequilibrium systems, the measuring principles to exploit properties in applications, the differences in designing lab experiments and devices, and several application examples.

The second part deals with the experimental characterization as well as the theoretical prediction of the mesostructure resulting from field-induced phase separation. The dynamics of phase separation is also included in this section. The third section is about the material properties; it includes papers on new compositions of ER or MR fluids, polymer blends, magneto- or electroactive elastomers and gels. The last section, about physical mechanisms, presents experiments and theories on the rheology of the fluids and its connection with microhydrodynamics and the structure of field-induced aggregates.
