DFT-Based Studies On Atomic Clusters explores the structures, properties, and applications of a variety of atomic clusters using density functional theory (DFT) methods to offer a simple and comprehensive explanation of the subject. The book is organized into seven chapters. Chapter 1 introduces atomic clusters and provides a quick survey of density functional theory and its role in the study of atomic clusters. Chapter 2 discusses the optimization of atomic clusters using various algorithms. Chapters 3, 4, and 5 cover the applications of DFT methods on chemical interactions involving metal complexes and ions. Chapter 6 is devoted exclusively to molecular clusters for completeness. Chapter 7 concludes the book and provides a perspective on future directions on the subject. Theoretical and practical concepts of DFT methods of the book are systematically and concisely presented with the help of clear language. Several illustrations in the form of graphics and tables are included for the benefit of readers. This reference is intended as a guide for advanced graduate and doctorate level scholars, postdoctoral researchers, and faculty members who are required to understand the application of density functional theory for explaining the properties of atomic clusters as part of foundational coursework or supplementary reading.

Biochar - Solid Carbon for Sustainable Agriculture explores the potential of biochar, a form of charcoal produced from organic materials, to improve soil health, increase crop yields, and mitigate climate change. This book offers a comprehensive overview of biochar and its applications in sustainable agriculture. The book begins by introducing the concept of biochar and its historical use in agriculture. Next, the content deals with the production methods and properties of biochar, providing insights into its chemical composition and physical characteristics. Subsequent chapters explore the diverse applications of biochar in agriculture, including its role in soil fertility improvement, carbon sequestration, and pollution remediation. Case studies and practical examples illustrate the effectiveness of biochar across different agricultural settings. The authors also discuss the potential challenges and future directions of biochar research and application. This book is essential reading for agronomists, soil scientists, environmental scientists, farmers, policymakers, and anyone interested in sustainable agriculture and climate change mitigation strategies.
