Zeta Potential has been known for more than one hundred years as a characteristic of the Interfacial Electric Double layer that control many properties and processes in dispersions, emulsions, and wet porous materials. It appears in many fundamental studies of such systems. It is a parameter used more and more in nanotechnology, biomedical and many other fields. However, due to the lack of corresponding education in colleges and graduate schools, many users, even some senior researchers, do not fully understand the concept and many mistakes appear in publications and applications. Recently, application of the zeta potential has expanded more into formulation and even quality control of these heterogeneous systems. The main goal of this book is to reflect this switch. In contrast to previously published books on this subject, it places emphasis on modern measurement methods that allow expansion in zeta potential usage and applications. Major focus is given to the three critical electrokinetic phenomena that serve as a basis for modern methods of zeta potential measurements: electrophoresis, electroacoustics and streaming current. The section on these methods will help the reader to navigate between different methods and select the one that is most appropriate for their application. The section on applications includes reviews of hundreds published papers so the reader can find previously published data on similar projects. Zeta Potential: Fundamentals, Methods, and Applications addresses the need for an up-to-date book focusing on the principles and practice of zeta potential measurements, providing readers with comprehensive and readily understandable coverage. It is suitable for an interdisciplinary audience of researchers, engineers and students who are involved in studying or using in industry complex heterogeneous liquids, like dispersions and emulsions, as well as wetted porous materials. This includes but is not limited to materials/colloids and interface chemists, chemical engineers, material scientists, biophysicists, and biochemists.
Resonance: Long-Lived Waves, a new volume in the Interface Transmission Tutorial Book series, introduces long-life resonance properties for telecommunications. The book's authors review the general analysis methods of interface transmission, giving many examples and applying these methods to telecommunications systems (materials and devices). Each chapter introduces and defines the long-lived resonances, their path states and phase shifts, and applications. This book is suitable for materials scientists and engineers in academia and R&D, and may also be appropriate for applied physicists.
In the past 30 years, magnetic research has been dominated by the question of how surfaces and interfaces influence the magnetic and transport properties of nanostructures, thin films and multilayers. The research has been particularly important in the magnetic recording industry where the giant magnetoresistance effect led to a new generation of storage devices including hand-held memories such as those found in the ipod. More recently, transfer of spin angular momentum across interfaces has opened a new field for high frequency applications.This book gives a comprehensive view of research at the forefront of these fields. The frontier is expanding through dynamic exchange between theory and experiment. Contributions have been chosen to reflect this, giving the reader a unified overview of the topic.
This volume provides a comprehensive and up to the minute review of the techniques used to determine the nature and composition of surfaces. Originally published as a special issue of the Pergamon journal Vacuum, it comprises a carefully edited collection of chapters written by specialists in each of the techniques and includes coverage of the electron and ion spectroscopies, as well as the atom-imaging methods such as the atom probe field ion microscope and the scanning tunnelling microscope. Surface science is an important area of study since the outermost surface layers play a crucial role in processses such as catalysis, adhesion, wear, and corrosion, with applications in metallurgy, thin films and surface coatings, the chemicals and polymer industries, and microelectronics, to name a few. This book covers those techniques used routinely for surface analysis as well as those employed for more fundamental scientific studies. It will be of interest to university research workers, graduate students and to industrial scientists solving practical problems.
Semiconductor Superlattices and Interfaces is concerned with the dynamic field of semiconductor microstructures and interfaces. Several topics in the fundamental properties of interfaces, superlattices and quantum wells are included, as are papers on growth techniques and applications. The papers deal with the interaction of theory, experiments and applications within the field, and the outstanding contributions are from both the academic and industrial worlds.
Methods of Surface Analysis deals with the determination of the composition of surfaces and the identification of species attached to the surface. The text applies methods of surface analysis to obtain a composition depth profile after various stages of ion etching or sputtering. The composition at the solid—solid interface is revealed by systematically removing atomic planes until the interface of interest is reached, in which the investigator can then determine its composition. The book reviews the effect of ion etching on the results obtained by any method of surface analysis including the effect of the rate of etching, incident energy of the bombarding ion, the properties of the solid, the effect of the ion etching on generating an output signal of electrons, ions, or neutrals. The text also describes the effect of the residual gases in the vacuum environment. The book considers the influence of the sample geometry, of the type (metal, insulator, semiconductor, organic), and of the atomic number can have on surface analysis. The text describes in detail low energy ion scattering spectroscopy, X-ray photoelectron spectroscopy, Auger electron spectroscopy, secondary ion mass spectroscopy, and infrared reflection-absorption spectroscopy. The book can prove useful for researchers, technicians, and scientists whose works involve organic chemistry, analytical chemistry, and other related fields of chemistry, such as physical chemistry or inorganic chemistry.
Surfaces and Interfaces: Physics and Electronics covers the proceedings of the second Trieste ICTP-IUPAP Semiconductor Symposium, conducted at the International Center for Theoretical Physics in Trieste, Italy on August 30 to September 3, 1982. The book focuses on the processes, methodologies, reactions, and approaches involved in semiconductor physics. The selection first elaborates on the electronic properties and surface geometry of GaAs and ZnO surfaces; electronic structure of Si (III) surfaces; and photoemission studies of surface states on Si (III) 2X1. Discussions focus on consistency of different experiments, relating experiments to a theoretical model, quenching of surface states by hydrogen, inverse photoemission results, and basic data and models of the low-index ZnO surfaces. The text then examines Si (III) 2X1 studies by angle resolved photoemission; electronic surface states at steps in Si (III) 2X1; and a novel method for the study of optical properties of surfaces. The manuscript takes a look at spot profile analysis (LEED) of defects at silicon surfaces; chemisorption-induced defects at interfaces on compound semiconductors; and surface defects on semiconductors. The microscopic properties and behavior of silicide interfaces, recombination at semiconductor surfaces and interfaces, and dipoles, defects, and interfaces are also discussed. The selection is a highly recommended source of data for physicists and readers wanting to study semiconductor physics.
This volume of the Handbook of Surface Science covers all aspects of the dynamics of surface processes. Two dozen world leading experts in this field address the subjects of energy exchange in gas atoms, surface collisions, the rules governing dissociative adsorption on surfaces, the formation of nanostructures on surfaces by self-assembly, and the study of surface phenomena using ultra-fast lasers. The chapters are written for both newcomers to the field as well as researchers.
The book is devoted to the consideration of the different processes taking place in thin films and at surfaces. Since the most important physico-chemical phenomena in such media are accompanied by the rearrangement of an intra- and intermolecular coordinates and consequently a surrounding molecular ensemble, the theory of radiationless multi-vibrational transitions is used for its description. The second part of the book considers the numerous surface phenomena. And in the third part is described the preparation methods and characteristics of different types of thin films. Both experimental and theoretical descriptions are represented. Media rearrangement coupled with the reagent transformation largely determines the absolute value and temperature dependence of the rate constants and other characteristics of the considered processes. These effects are described at the atomic or molecular level based on the multi-phonon theory, starting from the first pioneering studies through to contemporary studies.A number of questions are included at the end of many chapters to further reinforce the material presented.
