The book also treats the surface properties of apolar and polar molecules, polymers, particles and cells, as well as their mutual interaction energies, when immersed in water, under the influence of the three prevailing non-covalent forces, i.e., Lewis acid-base (AB), Lifshitz-van der Waals (LW) and electrical double layer (EL) interactions. The polar AB interactions, be they attractive or repulsive, typically represent up to 90% of the total interaction energies occurring in water. Thus the addition of AB energies to the LW + EL energies of the classical DLVO theory of energy vs. distance analysis makes this powerful tool (the Extended DLVO theory) applicable to the quantitative study of the stability of particle suspensions in water.-

The goal of Interface Science and Composites is to facilitate the manufacture of technological materials with optimized properties on the basis of a comprehensive understanding of the molecular structure of interfaces and their resulting influence on composite materials processes. From the early development of composites of various natures, the optimization of the interface has been of major importance. While there are many reference books available on composites, few deal specifically with the science and mechanics of the interface of materials and composites. Further, many recent advances in composite interfaces are scattered across the literature and are here assembled in a readily accessible form, bringing together recent developments in the field, both from the materials science and mechanics perspective, in a single convenient volume. The central theme of the book is tailoring the interface science of composites to optimize the basic physical principles rather than on the use of materials and the mechanical performance and structural integrity of composites with enhanced strength/stiffness and fracture toughness (or specific fracture resistance). It also deals mainly with interfaces in advanced composites made from high-performance fibers, such as glass, carbon, aramid, and some inorganic fibers, and matrix materials encompassing polymers, carbon, metals/alloys, and ceramics. Includes chapter on the development of a nanolevel dispersion of graphene particles in a polymer matrix Focus on tailoring the interface science of composites to optimize the basic physical principles Covers mainly interfaces in advanced composites made from high performance fibers

Theory of Electrophoresis and Diffusiophoresis of Highly Charged Colloidal Particles discusses the electrophoretic and diffusiophoretic motions of various colloidal entities, such as rigid particles, liquid droplets, gas bubbles, and porous particles, focusing on the motion-deterring double-layer polarization effect pertinent to highly charged particles, with the lowly charged ones serving as the limiting cases. Boundary effects such as those from a cylindrical pore, a solid plane, or an air-water interface are analyzed as well for the electrophoretic motion of the various particles considered. Dynamic electrophoresis is also explored and treated. The contents are suitable for researchers, graduate students, or senior college students with some basic background of colloid science and transport phenomena. As there is no closed-form analytical formula in general for the situation of highly charged particles, the results are presented with extensive figures and plots as well as tables under various electrokinetic situations of interest to facilitate the possible use of interested readers. Provides a reliable quantitative prediction of highly charged particles motion with easy-to-apply charts and in-depth understanding of the underlying mechanisms Offers an extensive treatment of direct quantitative predication for non-rigid systems, such as porous particles, liquid drops, and gels, which is especially valuable in proteins and DNA research Discusses highly charged systems with a nearby boundary of practical interests, such as a pore, a solid plane, or an air-water interface, which is of vital interest in fields such as microfluidic operations and biomedical engineering Affords special attention to the polarization effect

Colloidal systems occur everywhere—in soils, seawater, foodstuff, pharmaceuticals, paints, blood, biological cells, and microorganisms. Colloids and Interfaces in Life Sciences and Bionanotechnology, Second Edition, gives a concise treatment of physicochemical principles determining interrelated colloidal and interfacial phenomena. New in the Second Edition: New topics, including phase separations in polymer systems, electrokinetics of charged permeable surface coatings, and polymer brush coatings to control adsorption and adhesion of particles Emphasis on inter-particle interactions and surface phenomena in (bio)nanotechnology Full solutions to over 100 updated and additional exercises are presented in the Appendix Focusing on physicochemical concepts that form the basis of understanding colloidal and interfacial phenomena—rather than on experimental methods and techniques—this book is an excellent primer for students and scientists interested in colloidal and interfacial phenomena, their mutual relations and connections, and the fascinating role they play in natural and man-made systems.

The common perception is that nanoscience is something entirely new, that it sprung forth whole and fully formed like some mythological deity. But the truth is that like all things scientific, nanoscience is the natural result of the long evolution of scientific inquiry. Following a historical trail back to the middle of the 19th century, nanoscience is the inborn property of colloid and interface science. What’s important today is for us to recognize that nanoparticles are small colloidal objects. It should also be appreciated that over the past decades, a number of novel nanostructures have been developed, but whatever we call them, we cannot forget that their properties and behavior are still in the realm of colloid and interface science. However one views it, the interest and funding in nano-science is a tremendous opportunity to advance critical research in colloid chemistry. Nanoscience: Colloidal and Interfacial Aspects brings together a prominent roster of 42 leading investigators and their teams, who detail the wide range of theoretical and experimental knowledge that can be successfully applied for investigating nanosystems, many of which are actually well-known colloidal systems. This international grouping of pioneering investigators from academia and industry use these pages to provide researchers of today and tomorrow with a full examination of nano-disperse colloids, homogeneous and heterogeneous nano-structured materials (and their properties), and shelf-organization at the nano-scale. This cutting-edge reference provides information on investigations into non-linear electrokinetic phenomena in nano-sized dispersions and nano-sized biological systems. It discusses application aspects of technological processes in great detail, providing scientists and engineers across all fields with authoritative commentary on colloid and interface science operating at the nanoscale. Nano-Science: Colloidal and Interfacial Aspects provides an authoritative resource for those wanting to familiarize themselves with current progress as well as for those looking to make their own impact on the development of new technologies and practical applications in fields as diverse as medicine, materials, and environmental science to name but a few. Whether you call the technology nano or colloids, the field continues to be ripe with opportunity.
