This book provides a comprehensive overview of positron profilometry, specifically focusing on the analysis of defect depth distribution in materials. Positron profilometry plays a crucial role in understanding and characterizing defects in a wide range of materials, including metals, semiconductors, polymers, and ceramics. By analyzing the depth distribution of defects, researchers can gain insights into various material properties, such as crystal structure, defect density, and diffusion behavior. The author's extensive research spanning a period of two decades has primarily centered on subsurface zones. These regions, located beneath the surface and subjected to various surface processes, play a crucial role in generating defect distributions. Three experimental techniques and their data analysis are described in detail: a variable-energy positron beam (VEP) called sometimes a slow positron beam, a technique called implantation profile depth scanning (DSIP), and a sequential etching(SET) technique. The usability of these techniques is illustrated by many examples of measurements by the author and others.

This book is based on a course of lectures aimed at undergraduate and graduate students studying materials science and welding at the E.O. Paton Institute of Materials Science and Welding National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute." The book is divided into four parts, each focusing on various aspects of magnetic solitons in ferromagnetic nanosystems.The first two parts of the book cover the quantum and thermodynamic properties of uniaxial ferromagnetic films with strong magnetic anisotropy and cylindrical nanowires made of different chemical compositions (ferrite-garnet, iron, nickel). These properties are related to the presence of "kink" solitons, which are vertical Bloch lines (BLs) and domain walls (DWs) of transverse type, respectively.The third part of the book discusses the effect of thermal motion of transverse-type DWs on the magnetocaloric effect in cylindrical iron and nickel nanowires. The fourth part of the book explores the conditions that lead to structural transitions between different types of DWs, including transverse, asymmetric, and DWs with a Bloch point (point soliton).Each part of the book is summarized at the end, highlighting the main results presented. Overall, the book is designed to provide students with a comprehensive understanding of magnetic solitons in ferromagnetic nanosystems and their associated quantum, thermodynamic, and structural properties.

This book briefly looks at numerical modeling and micromagnetic simulation results of magnonic crystals, which are periodically modulated magnonic devices regarded as the magnetic counterpart of photonic crystals with spin waves acting as the information carrier. Since the wavelength of the spin wave is several orders of magnitude shorter than that of electromagnetic waves of the same frequency, magnonic crystals are promising candidates for miniaturization, especially in the fields of data storage and processing. The book begins by describing the dispersion relation of dipolar spin waves in a magnonic curved waveguide, solving Walker's equation in cylindrical coordinates, and then calculating the dispersion of exchange spin waves using perturbation theory. It describes simulated nano-contact-driven spin wave excitations in a magnonic cavity, featuring a design of an antidot magnonic crystal around the nano-contact, with the frequency of the spin wave mode generated lying within the band gap of the magnonic crystal. The proposed device behaves as a SWASER¿Spin Wave Amplification by the Stimulated Emission of Radiation. This book will find interest among researchers and practitioners interested in the modeling, simulation, and design of novel magnonic devices.

This book covers the recent development of metal oxides, hydroxides and their carbon composites for electrochemical oxidation of water in the production of hydrogen and oxygen as fuels. It includes a detailed discussion on synthesis methodologies for the metal oxides/hydroxides, structural/morphological characterizations, and the key parameters (Tafel plot, Turnover frequency, Faradic efficiency, overpotential, long cycle life etc.) needed to evaluate the electrocatalytic activity of the materials. Additionally, the mechanism behind the electro oxidation process is presented. Readers will find a comprehensive source on the close correlation between metal oxides, hydroxides, composites, and their properties and importance in the generation of hydrogen and oxygen from water.The depletion of fossil fuels from the earth's crust, and related environmental issues such as climate change, demand that we search for alternative energy resources to achieve some form of sustainable future. In this regard, much scientific research has been devoted to technologies such as solar cells, wind turbines, fuel cells etc. Among them fuel cells attract much attention because of their versatility and efficiency. In fuel cells, different fuels such as hydrogen, CO2, alcohols, acids, methane, oxygen/air, etc. are used as the fuel, and catalysts are employed to produce a chemical reaction for generating electricity. Hence, it is very important to produce these fuels in an efficient, eco-friendly, and cost effective manner. The electrochemical splitting of water is an environmentally friendly process to produce hydrogen (the greener fuel used in fuel cells), but the efficiencies of these hydrogen evolution reactions (cathodic half reaction) are strongly dependent on the anodic half reaction (oxygen evolution reaction), i.e., the better the anodic half, the better will be the cathodic reaction. Further, this oxygen evolution reaction depends on the types of active electrocatalysts used. Though many more synthetic approaches have been explored and different electrocatalysts developed, oxide and hydroxide-based nanomaterials and composites (with graphene, carbon nanotubes etc.) show better performance. This may be due to the availability of more catalytic surface area and electro active centers to carry out the catalysis process.

This book provides a concise but comprehensive introduction to the fundamentals and current state of the art in thermoelectrics. Addressing an audience of materials scientists and engineers, the book covers theory, materials selection, and applications, with a wide variety of case studies reflecting the most up-to-date research approaches from the past decade, from single crystal to polycrystalline form and from bulk to thin films to nano dimensions. The world is facing major challenges for finding alternate energy sources that can satisfy the increasing demand for energy consumption while preserving the environment. The field of thermoelectrics has long been recognized as a potential and ideal source of clean energy. However, the relatively low conversion efficiency of thermoelectric devices has prevented their utility on a large scale. While addressing the need for thermal management in materials, device components, and systems, thermoelectrics provides a fundamental solution to waste heat recovery and temperature control.This book summarizes the global efforts that have been made to enhance the figure of merit of various thermoelectric materials by choosing appropriate processes and their influence on properties and performance. Because of these advances, today, thermoelectric devices are found in mainstream applications such as automobiles and power generators, as opposed to just a few years ago when they could only be used in niche applications such as in aeronautics, infrared imaging, and space. However, the continued gap between fundamental theoretical results and actual experimental data of figure of merit and performance continues to challenge the commercial applications of thermoelectrics. This book presents both recent achievements and continuing challenges, and represents essential reading for researchers working in this area in universities, industry, and national labs.
