With the rapid development of nanotechnology, the surface-to-volume ratio of objects of interest continues to increase. As such, so does the importance of our ability to tailor interfacial properties. Written by bestselling author and internationally renowned researcher K.S. Birdi, Introduction to Electrical Interfacial Phenomena offers comprehensive coverage of the field of electrical double layer (EDL) research. Birdi discusses theoretical models used with EDL and demonstrates how they can be applied to typically encountered real-world problems, including those that must be considered in modern industrial applications. The book explains the EDL through fundamental theory and real-world solved examples from applications such as corrosion, aerosols, dispersions and emulsions, adhesion, storage batteries, waste-water treatment, enhanced oil recovery, biology (proteins at cell membranes), and macromolecules. After introducing the electrical interfacial phenomenon, it describes advanced systems, provides a comprehensive description of the double layer, and presents bonus material on advanced theory separate from the main text. The book also includes application examples that demonstrate EDL analyses to new and developing areas such as enhanced oil recovery, storage batteries, hydrogen fuel cells, and biology. While there are many books available on this topic, so far none have taken a combined application and fundamental theoretical approach to the problem. Collating available information drawn from the extensive literature on various models of EDL into a comprehensive resource, this book paints a picture of the state of an art that is on the brink of further development. It not only delineates theoretical models, but also demonstrates how they can be applied to real problems.

The book summarizes recent international research and experimental developments regarding fatigue crack growth investigations of rubber materials. It shows the progress in fundamental as well as advanced research of fracture investigation of rubber material under fatigue loading conditions, especially from the experimental point of view. However, some chapters will describe the progress in numerical modeling and physical description of fracture mechanics and cavitation phenomena in rubbers. Initiation and propagation of cracks in rubber materials are dominant phenomena which determine the lifetime of these soft rubber materials and, as a consequence, the lifetime of the corresponding final rubber parts in various fields of application. Recently, these phenomena became of great scientific interest due to the development of new experimental methods, concepts and models. Furthermore, crack phenomena have an extraordinary impact on rubber wear and abrasion of automotive tires; and understanding of crack initiation and growth in rubbers will help to support the growthing number of activities and worldwide efforts of reduction of tire wear losses and abrasion based emissions.
This volume, occasioned by the centenary of the Fritz Haber Institute, formerly the Institute for Physical Chemistry and Electrochemistry, covers the institute's scientific and institutional history from its founding until the present. The institute was among the earliest established by the Kaiser Wilhelm Society, and its inauguration was one of the first steps in the development of Berlin-Dahlem into a center for scientific research. Its establishment was made possible by an endowment from Leopold Koppel, granted on the condition that Fritz Haber, well-known for his discovery of a method to synthesize ammonia from its elements, be made its director. The history of the institute has largely paralleled that of 20th-century Germany. It undertook controversial weapons research during World War I, followed by a "Golden Era" during the 1920s, in spite of financial hardships. Under the National Socialists it experienced a purge of its scientific staff and a diversion of its research into the service of the new regime, accompanied by a breakdown in its international relations. In the immediate aftermath of World War II it suffered crippling material losses, from which it recovered slowly in the post-war era. In 1953, shortly after taking the name of its founding director, the institute joined the fledgling Max Planck Society. During the 1950s and 60s, the institute supported diverse researches into the structure of matter and electron microscopy in a territorially insular and politically precarious West-Berlin. In subsequent decades, as both Berlin and the Max Planck Society underwent significant changes, the institute reorganized around a board of coequal scientific directors and a renewed focus on the investigation of elementary processes on surfaces and interfaces, topics of research that had been central to the work of Fritz Haber and the first "Golden Era" of the institute.

Over the past several decades, the theme of supramolecular chemistry (SC) has permeated nearly all aspects of chemical endeavor. Not surprisingly, it has also pervaded the field of solvent extraction (SX), inspiring the framework for this volume of Ion Exchange and Solvent Extraction. In addition, tools for studying aggregation have grown increasingly sophisticated, leading to a greater understanding of what we now recognize as SC phenomena in SX. Volume 21, Supramolecular Aspects of Solvent Extraction identifies how supramolecular behavior occurs and is studied in the context of SX and how SC is influencing the direction of SX. With contributions by internationally recognized specialists from different fields, this volume examines how principles of SC are being used in advancing the design of new highly selective SX systems and for understanding aggregation phenomena in SX systems. The book begins with a discussion of the nature and definition of SC and its general use in the design of novel SX reagents. Chapter 2 expands the subject of ion-pair recognition to introduce outer-sphere recognition of metal complexes. Chapter 3 reviews the literature on calixarenes as extraction reagents for metal ions. Chapter 4 extends the utility of this chemistry, describing the use of calixarenes for the extraction of biomolecules. Chapter 5 examines the liquid-liquid interface as an expression of supramolecular phenomena in SX, reviewing interfacial aggregation in model two-phase systems and metal extraction systems. The final chapter explores the problem of aggregation in SX, the historical attempts to understand it, and recent progress that has been made in addressing the issue.
The demands of production, such as thin films in microelectronics, rely on consideration of factors influencing the interaction of dissimilar materials that make contact with their surfaces. Bond formation between surface layers of dissimilar condensed solids-termed adhesion-depends on the nature of the contacting bodies. Thus, it is necessary to determine the characteristics of adhesion interaction of different materials from both applied and fundamental perspectives of surface phenomena. Given the difficulty in obtaining reliable experimental values of the adhesion strength of coatings, the theoretical approach to determining adhesion characteristics becomes more important. Surface Physics: Theoretical Models and Experimental Methods presents straightforward and efficient approaches and methods developed by the authors that enable the calculation of surface and adhesion characteristics for a wide range of materials: metals, alloys, semiconductors, and complex compounds. The authors compare results from the proposed theories-developed within the framework of the electron density functional theory and dielectric formalism-to experimental data. The book begins with a discussion of the thermodynamics of surface phenomena and covers experimental and theoretical methods for studying surface characteristics of solids. Chapters describe calculations of surface and adhesion characteristics of metals using the density functional method. They also examine the calculation of adhesion characteristics of metals, semiconductors, and complex compounds based on dielectric formalism. In addition, the text covers dry friction, adsorption of metal atoms, and ferromagnetic films. The principles and methods presented in this book are useful in selecting optimum materials and coatings for various applications, including minimizing friction for increased efficiency of microelectronic components.
Cubes, triangular prisms, nano-acorn, nano-centipedes, nanoshells, nano-whiskers. . . . Now that we can create nanoparticles in a wide variety of shapes and morphologies, comes the next challenge: finding ways to organize this collection of particles into larger and more complex systems. Nanoparticle Assemblies and Superstructures, edited by pioneer of nanoparticle self-organization Nicholas A. Kotov, employs three critical questions to provide a framework of open-ended inquiry: What are the methods of organization of nanocolloids in more complex structures? What kind of structures do we need? What are the new properties appearing in nanocolloid superstructures? Pulling together a collection of contributors unmatched in both their expertise and enthusiasm, Kotov presents what he refers to as a snapshot of nanoassembly work in progress. The first section of this comprehensive volume provides background through an assessment of the current status of nanoparticle assembly development and the requirements for different applications of organized nanomaterials. The middle chapters explore the changes that occur in various properties of individual particles when they are brought together to form agglomerates and simple assemblies. In the final section, a number of top scientists describe various methods for organizing particles in complex nanostructured superstructures. These include techniques involving biological ligands and force fields, as well as methods based on self-organization. This remarkably prescient text upholds Kotov's belief that the research on organization of nanoparticles and other nanostructures, will most certainly uncover a wealth of "interesting discoveries and surprising phenomena." Nicholas A. Kotov has received several state, national, and international awards for his research on nanomaterials, including the Mendeleev Stipend, the Humboldt Fellowsh
