Book Description
In a rare, over-the-shoulder perspective of a leading scientist’s own breakthroughs, Clay Swelling and Colloid Stability puts emphasis on two significant paradigm shifts in colloid science that explain particle interactions for charged plates, stacks, suspensions, and pastes as well as spherical colloids. Martin Smalley first discusses the replacement of the DLVO theory with the Coulombic Attraction Theory to explain the existence, extent, and properties of the two-phase region of colloid stability. Using the n-butylammonium vermiculite system as his model clay system, the author clarifies the flaws of conventional theories and presents the experimental details that form the basis of his new theories. He provides rigorous derivations that place the new electrical theory for charged colloids on a firm foundation in statistical mechanics. The author illustrates why a new, quantitative bridging flocculation model for polymer-stabilized colloids must replace the depletion flocculation model. Smalley also examines the discovery of the "dressed macroion" structure of clay plates in solution, the structure of a bridging polymer, and the distribution of polymer segments, counterions, and water molecules in the interlayer region. Based on the author’s own research and 36 publications in the field, Clay Swelling and Colloid Stability isa self-contained and intellectually satisfying account of the revolutionary process leading to a universally sound, and increasingly applicable, theory of colloid stability.

Book Description
Clays are increasingly becoming a major problem in the mining, extraction and value-adding processes for a wide range of commodity raw materials. Clays can impact negatively on virtually every unit process within the mining and minerals processing sector, having long-term environmental implications that go well beyond the lifetime of the mining operation. This book is the first to compile, explain and evaluate the effects of clays in the mineral processing value chain, from mining to minerals processing, and finally, tailings disposal. Focusing on topics from the chemistry and rheology of clays to their detection and dissolution behaviour, this book provides comprehensive coverage of the effects on processes such as settling, preg-robing, flotation and comminution. It is an excellent reference for professional mineralogists and geologists, industrial engineers, and researchers interested in clays and clay minerals.

Book Description
The Derjaguin-Landau-Verwey-Overbeek theory has been extensively used to explain dispersion and flocculation in colloidal systems, however little is known about the effect of crystalline swelling on colloidal behavior. The first topic addressed in the dissertation is the effect of monovalent and divalent cations on crystalline swelling and the breakup and formation of quasicrystals (QCs) and how these processes affect flocculation and dispersion of natural soil clay-humic complexes. The results indicate that high Ca2 levels enhance the formation of large QCs, which readily flocculate and settle out of suspension. Increasing the concentration of Na+, K+, or NH4+ results in the breakup of large Ca-QCs, which enhances dispersion. The second part of the dissertation addresses the influence of soil smectites and humic substances and their interactions on sorption and desorption of tetracyclines. Tetracyclines are important in human medicine and are also used extensively in livestock production. Chlortetracycline and tetracycline are routinely used for growth promoting and therapeutic purposes in livestock production. To elucidate the environmental fate of these pharmaceuticals, sorption isotherms were obtained using dilute CaCl2 or KC1 background solutions at different pHs for clays, humic substances, and clay-humic complexes. In all systems, the soil components sorbed> 96% of added tetracyclines. The results indicate that tetracyclines are dominantly sorbed on soil clays and that HS compete with tetracyclines for sorption sites on the clay surfaces. The third topic addressed in the dissertation is degradation and bioavailability of TC when it is adsorbed to whole soils, soil clay-HC, and soil clays. Specifically studied was the degradation of TC in both aqueous and colloidal systems, the antimicrobial activity of sorbed TC, whether sorbed TC is a long-term reservoir for slow TC release, and the ability of TC resistant bacteria to degrade sorbed TC. Studies indicated that sorbed TC inhibits soil bacteria, however, most likely due to slow TC release from soil components. Most of the adsorbed TC was retained by the soil and soil components in a form that was not released during the 149-day incubation. This stable pool of adsorbed TC appeared to be primarily associated with organic matter and humic substances.

Book Description
The first general texts on clay mineralogy and the practical applications of clay, written by R.E. Grim, were published some 40-50 years ago. Since then, a vast literature has accumulated but this information is scattered and not always accessible. The Handbook of Clay Science aims at assembling the scattered literature on the varied and diverse aspects that make up the discipline of clay science. The topics covered range from the fundamental structures (including textures) and properties of clays and clay minerals, through their environmental, health and industrial applications, to their analysis and characterization by modern instrumental techniques. Also included are the clay-microbe interaction, layered double hydroxides, zeolites, cement hydrates, genesis of clay minerals as well as the history and teaching of clay science. No modern book in the English language is available that is as comprehensive and wide-ranging in coverage as the Handbook of Clay Science.In providing a critical and up-to-date assessment of the accumulated information, this will serve as the first point of entry into the literature for both newcomers and graduate students, while for research scientists, university teachers, industrial chemists, and environmental engineers the book will become a standard reference text.* Presents contributions from 66 authors from 18 different countries who have come together to produce the most comprehensive modern handbook on clay science* Provides up-to-date concepts, properties, and reactivity of clays and clay minerals in a one-stop source of information* Covers classical and new environmental, industrial, and health applications of clays, as well as the instrumental techniques for clay mineral analysis* Combines geology, mineralogy, crystallography with physics, geotechnology, and soil mechanics together with inorganic, organic, physical, and colloid chemistry for a truly multidisciplinary approach

Book Description
This book focuses on inorganic nanosheets, including various oxides, chalcogenides, and graphenes, that provide two-dimensional (2D) media to develop materials chemistry in broad fields such as electronics, photonics, environmental science, and biology. The application area of nanosheets and nanosheet-based materials covers the analytical, photochemical, optical, biological, energetic, and environmental research fields. All of these applications come from the low dimensionality of the nanosheets, which anisotropically regulate structures of solids, microspaces, and fluids. Understanding nanosheets from chemical, structural, and application aspects in relation to their "fully nanoscopic" characters will help materials scientists to develop novel advanced materials. This is the first book that accurately and concisely summarizes this field including exfoliation and intercalation chemistries of layered crystals. The book provides perspective on the materials chemistry of inorganic nanosheets. The first section describes fundamental aspects of nanosheets common to diverse applications: how unique structures and properties are obtained from nanosheets based on low dimensionality. The second section presents state-of-the-art descriptions of how the 2D nature of nanosheets is utilized in each application of the materials that are developed.
