Polysaccharides are organic polymers in which the repeating unit consists of monosaccharides. They exist in plants, animals, algae, or microbial worlds. Chitosan is a cationic linear polysaccharide of glucosamine produced from chitin deacetylation in alkaline media. Chitin is obtained from the exoskeleton of shrimps, crabs, and squids. Therefore, chitosan is environmentally benign and biodegradable. This book summarizes different aspects of chitosan and its derived materials, addressing isolation, properties, and applications. This book is intended for academics, professionals, and scientists as well as graduate and undergraduate students without any geographical limitations.

Green Chemistry - New Perspectives is at the frontiers of this continuously evolving interdisciplinary science, and publishes research that attempts to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The book covers all aspects of green chemistry, including chemical synthesis, nano synthesis, eco-friendly processes, biomass, extraction techniques, environmental remediation, and energy, making it a unique reference resource. This will continue to encourage scientists around the world to develop novel synthetic methods or improve the existing ones to circumvent some of the problems and favours all aspects of green chemistry. This book is intended for academia, professionals, scientists, as well as graduate and undergraduate students without any geographical limitations.

Nanoparticles in Green Organic Synthesis: Strategy towards Sustainability presents the fundamental and latest practical uses of metal nanoparticles (MNPs) in organic synthesis, as well as their promising multidimensional applications. The book examines the latest emerging research on MNP synthesis and their applications‿from organic transformation to energy and the environment‿allowing readers to critically analyze the role of different MNPs in seeking ideas for widespread application. The book covers the fundamentals while also providing a comprehensive account of MNPs and their modification for a variety of green platform-based derivatives, focusing on the multifunctional technological evolution.  The book covers a wide range of applications in organic synthesis using a variety of transition-metal-based nanoparticles in both homo- and heterogeneous media. The text details the concept of catalyst design and recent developments in the preparation and characterization of nanomaterials, followed by several chapters on the design of catalysts for specific applications. This volume is a valuable resource for those working in green chemistry, sustainability, material science and engineering, nanotechnology, energy, and the environment.
