This thesis makes significant advances towards an understanding of superconductivity in the cuprate family of unconventional, high-temperature superconductors. Even though the high-temperature superconductors were discovered over 35 years ago, there is not yet a general consensus on an acceptable theory of superconductivity in these materials. One of the early proposals suggested that collective magnetic excitations of the conduction electrons could lead them to form pairs, which in turn condense to form the superconducting state at a critical temperature Tc. Quantitative calculations of Tc using experimental data were, however, not available to verify the applicability of this magnetic mechanism. In this thesis, the author constructed an angle-resolved photoemission apparatus that could provide sufficiently accurate data of the electronic excitation spectra of samples in the normal state, data which was furthermore unusually devoid of any surface contamination. The author also applied the Bethe-Salpeter method to his uncommonly pristine and precise normal state data, and was able to predict the approximate superconducting transition temperatures of different samples. This rare combination of experiment with sophisticated theoretical calculations leads to the conclusion that antiferromagnetic correlations are a viable candidate for the pairing interaction in the cuprate superconductors.

This book covers the physical metallurgy of steels as well as the heat treatments used to improve the their properties. A full chapter is dedicated to the atmospheres in the steelmaking, including the implications of the own gases generated in the iron and steelmaking factories and how they could be applied in these treatments. This book is specially conceived for graduate and undergraduate courses, being the result of more than 30 years of teaching experience in courses for undergraduate, graduate (master and Ph. D.), and companies (technicians). The trends in the re-utilization of industrial gases in the iron and steelmaking process are discussed by the authors. Additionally, the book comprises 41 solved exercises, problems and case-studies, as a complement of the theoretical sections of the text. These exercises, problems, and case-studies are based on problems observed in the industrial practice.

"Sustainable Packaging Materials" provides a concise introduction to the principles and practices of packaging sustainability. It addresses the important issues that concern packaging professionals, decision makers, managers, CTOs, legislators, researchers, and students, including the viability and future of recycling, bio- and oxo-degradable materials, and plastics alternatives such as paper, glass, and metal. Also covered are new regulations such as the extended producer responsibility (EPR) laws, their consequences as to what materials are likely to be banned, and whether microplastics should be a concern for packaging companies.Written by an experienced professor, educator, author, inventor, and entrepreneur, this book offers uniquely clear answers to these challenges, helping readers to identify packaging materials that are likely to be phased out to meet new regulations, and to find alternatives to benefit their research and businesses. They will also be equipped to follow guidelines on the use of various packaging materials to stay ahead of the demands of the industry, and to make informed choices about packaging materials by considering sustainability, performance, and cost. Furthermore, they will be informed of the emerging packaging trends in both academia and industry, and understand the issues associated with microplastic pollution, and the actions recommended to mitigate these challenges.

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.

Forgeries present a daunting problem to art historians, museums, galleries and curators who face challenges in determining the authenticity of paintings. Recent progress in science has led to the development of new methods for investigating works of art, and can provide new insights into the materials found in paintings. The rise in the value of paintings together with the knowledge and skills of forgers highlights the need to develop reliable scientific procedures to identify fakes. Given the complexity of materials in paintings and the convergence of various disciplines, a methodological approach for nvestigations of paintings is based on art historical, curatorial, aesthetic, technical and scientific evaluation. In this book sophisticated digital and analytical techniques are reviewed for the identification of materials (pigments, binders, varnishes, adhesives) and the physical characteristics of paintings such as brushstrokes, craquelure and canvas weaves. This book presents an updated overview of both non-invasive and micro-invasive techniques that enable the material characterization of paintings. The materials constituting a painting are reviewed, as are ways that changes in materials over time can provide insights into chronology and physical history. State-of the art digital metods including multi and hyper-spectral imaging and computational approaches to data treatment will be presented. Analytical techniques developed and optimized to characterize binders, varnishes, and pigments are reviewed, focusing on materials which can provide information on ageing or provenance. Case studies of applications of synchrotron-based methods and the analysis of paintings are given, as are chapters devoted to legal aspects related to authenticity.
