Deep eutectic solvents (DESs) and natural deep eutectic solvents (NADES) have emerged as transformative materials in the pursuit of sustainable and environmentally responsible chemistry. Their remarkable physicochemical properties, low toxicity, tunable structures, and broad applicability position them as powerful alternatives to conventional solvents and catalysts across diverse scientific and industrial fields. From catalysis, extraction, and electrochemistry to pharmaceuticals, polymerization, agriculture, and energy storage, DESs are redefining modern approaches to green chemical processes and materials design.This book provides a comprehensive overview of the latest advances in DES and NADES research, covering both fundamental principles and practical applications. It explores the environmental profile, synthesis strategies, physicochemical behavior, and industrial relevance of these innovative solvent systems, while also highlighting emerging developments in machine learning-guided solvent discovery, CO₂ recycling, biocatalysis, cryoprotection, and advanced DES@MOF hybrid materials.Special emphasis is placed on sustainable technologies and industrial translation, demonstrating how DESs can bridge the gap between laboratory innovation and real-world implementation. The book further examines techno-economic considerations, patent landscapes, and challenges associated with large-scale adoption, offering valuable perspectives for future development.Features:• Comprehensive coverage of DESs and NADES in sustainable chemistry.• Emerging applications in catalysis, pharmaceuticals, polymers, agriculture, and energy systems.• Insights into machine learning, industrial production, and techno-economic aspects.• Discussion of environmental impact, toxicity, biodegradability, and green processing.This book serves as a valuable reference for researchers, academicians, industry professionals, and policymakers working in green chemistry, materials science, chemical engineering, and sustainable technologies.
