Interfacial phenomena play a crucial role in various industrial processes and daily operations. These phenomena are related to the formation of emulsions and foams, adsorption on solid and fluid interfaces, wettability alteration, and others that strongly impact the quality and cost of products and processes. Understanding the interfacial phenomena encompasses inexorably the description of surface thermodynamics and the assessment of thermodynamic properties. The book Fundamentals of Surface Thermodynamics introduces the basics of the thermodynamics of interface from a perspective of chemical engineering thermodynamics and surface chemistry. It provides insights into real-life phenomena, emphasizing the practical significance of abstract properties routinely dealt with by scientists and engineers. The book is tailored for both graduate and undergraduate courses in chemistry and engineering schools. The book content is particularly beneficial for industry professionals involved in oil & gas, fluid transportation, nanotechnology, and other operations with multiphase complex systems, where the process effectiveness is affected by interfacial phenomena.The Fundamentals of Surface Thermodynamics brings a comprehensive description of colloidal science, ranging from conventional surfactant applications to responsive systems and nanomaterials applied to life science. The author invites the reader on a journey into the fascinating world where small-dimension entities breathe. The book aims to inspire students and professionals to delve deep into the intricacies of interface thermodynamics, thereby contributing to supporting education activities and enabling industrial solutions.

This thesis demonstrates the value of theoretical approaches in the discovery of new superconducting materials. It reports a detailed study of the recently discovered nickel-oxide (nickelate) superconductors using multiple first-principles computational tools, from density functional theory to dynamical mean field theory. In the context of superconductivity, discoveries have generally been linked to serendipitous experimental discovery; this thesis reports some of the few examples of predictions of new superconductors that have later been realized in practice, a prime example of the significance of the methodology it expounds. Overall, it represents a seminal systematic work in the electronic structure theory of the emergent field of nickelate superconductivity.

This book undertakes an extensive exploration of manganese-based compounds, such as T¿¿¿SrxMnO¿ (T = La, Pr; x = 0.35, 0.25) using density functional theory and Monte Carlo simulations with a focus on understanding their electronic, magnetic, and magnetocaloric properties. Bä¿¿SrxFeO¿ (x = 0, 0.2) is also studied via different approximations, offering a comparative perspective. In addition, the book looks at the influence of magnetism using Monte Carlo simulations, revealing crucial parameters and examining the GdCrO¿ system through DFT and Monte Carlo simulation, shedding light on recent experimental observations. Additionally, Monte Carlo studies investigate magnetic and magnetocaloric features of Sr¿FeMoO¿, LäSrMn¿O¿ bilayer manganite, perovskite ferromagnetic thin films' surface effects, and SmFe¿¿¿MnxO¿ perovskite. In essence, this book significantly advances our comprehension of magnetic and magnetocaloric phenomena across diverse materials and is well-suited for both experimentalists and computational researchers working in this field.
