The Properties of Water and their Role in Colloidal and Biological Systems Excerpt :

This book treats the different current as well as unusual and hitherto often unstudied physico-chemical and surface-thermodynamic properties of water that govern all polar interactions occurring in it. These properties include the hyper-hydrophobicity of the water-air interface, the cluster formation of water molecules in the liquid state and the concomitant variability of the ratio of the electron-accepticity to electron-donicity of liquid water as a function of temperature, T. The increase of that ratio with T is the cause of the increase in hydration repulsion (“hydration pressure ) between polar surfaces upon heating, when they are immersed in water. 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 influence of AB forces on the interfacial tension between water and other condensed-phase materials is stressed and serves, inter alia, to explain, measure and calculate the driving force of the hydrophobic attraction between such materials (the “hydrophobic effect ), when immersed in water. These phenomena, which are typical for liquid water, influence all polar interactions that take place in it. All of these are treated from the viewpoint of the properties of liquid water itself, including the properties of advancing freezing fronts and the surface properties of ice at 0o C

Theory of Electrophoresis and Diffusiophoresis of Highly Charged Colloidal Particles Excerpt :

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

Self Assembly of Nanostructures and Patchy Nanoparticles Excerpt :

Top-down approaches are currently the main contributor of fabricating microelectronic devices. However, the prohibitive cost of numerous technological steps in these approaches is the main obstacle to further progress. Furthermore, a large number of applications necessitate fabrication of complex and ultra-small devices that cannot be made using these approaches. New approaches based on natural self-assembly of matter need to be developed to allow for fabrication of micro and nanoelectronic devices. Self-assembly of nanostructures is a dynamic field, which explores physics of these structures and new ways to fabricate them. However, the major problem is how to control the properties of the nanostructures resulting from low dimensionality. This book presents recent advances made to address this problem, and fabricate nanostructures using self-assembly.

Interface Science and Composites Excerpt :

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
