Written for both newcomers and experienced researchers. While there are extensive experimental observations and established ideas regarding desorption of ions from the surfaces of aqueous salt solutions, a more successful discussion of the theory has recently emerged, which allows the quantitative calculation of the distribution of ions in the surface region. Unifying older and newer theories and measurements, this book emphasizes the contributions of simple ions to surface tension behavior, and the practical consequences.
It begins with a general discussion on Gibbs surface thermodynamics, offering a guide to his theoretical insight and formulation of the boundary between fluids. Interfacial Chemistry of Rocks and Soils examines the different processes at solid and liquid interfaces of soil and rock, presenting a complete analysis that emphasizes the importance of chemical species on these interactions.
This Second Edition features novel results in the field and expanded coverage of the kinetics of interfacial processes.
New content includes models of heterogeneous isotope exchange, sorption isotherms for heterovalent cation exchange, as well as sorption of anions by chemically modified clays. Among the physicochemical methods that give useful information regarding these complex phenomena, nuclear magnetic resonance NMR spectroscopy is the most universal, yielding detailed structural data regarding molecules, solids, and interfaces.
Nuclear Magnetic Resonance Studies of Interfacial Phenomena summarizes NMR research results collected over the past three decades for a wide range of materials—from nanomaterials and nanocomposites to biomaterials, cells, tissues, and seeds. This book describes the applications of important new NMR spectroscopic methods to a variety of useful materials and compares them with results from other techniques such as adsorption, differential scanning calorimetry, thermally stimulated depolarization current, dielectric relaxation spectroscopy, infrared spectroscopy, optical microscopy, and small-angle and wide-angle x-ray scattering.
The text explores the application of NMR spectroscopy to examine interfacial phenomena in objects of increasing complexity, beginning with unmodified and modified silica materials. It then describes properties of various mixed oxides with comparisons to individual oxides and also describes carbon materials such as graphite and carbon nanotubes. Chapters deal with carbon—mineral hybrids and their mosaic surface structures, and interfacial phenomena at the surface of natural and synthetics polymers.
They also explore a variety of biosystems, which are much more complex, including biomacromolecules proteins, DNA, and lipids , cells and tissues, and seeds and herbs. Significantly revised and updated, the Second Edition features new chapters that cover spreading of non-Newtonian liquids over porous substrates, hysteresis of contact angles on smooth homogeneous substrates, equilibrium and hysteresis contact angles on deformable substrates, and kinetics of simultaneous spreading and evaporation.
Drawing together theory and experimental data while presenting over figures to illustrate the concepts, Wetting and Spreading Dynamics, Second Edition is a valuable resource written for both newcomers and experienced researchers.
Surface tension provides a thermodynamic avenue for analyzing systems in equilibrium and formulating phenomenological explanations for the behavior of constituent molecules in the surface region.

Silicone is an important class of materials used in applications that range from industrial assembly to everyday consumer products.
Silicones are often delivered and synthesized in dispersion forms, the most common being liquid-in-liquid emulsion , solid-in-liquid suspension , air-in-liquid foam and solid-in air powder. This book compiles a carefully selected number of topics that are essential to the understanding, creative design and production of silicone dispersions. As such, it provides the first unified description of silicone dispersions in the literature.
