Back cover copy

The field of renewable resources is burgeoning today more than ever. Thus, cellulose science is one of the most scientifically active research fields today in the framework of bioeconomy trends and related fields of biorefineries and biomass utilization. Cellulose Science and Technology: Chemistry, Analysis, and Applications addresses concepts and novel developments in the rapidly evolving field of cellulose chemistry, providing an emphasis on the fundamental aspects of nanocellulose and microfibrillated cellulose. Featuring contributions from leading cellulose scientists worldwide, the book describes current attempts to provide and widen the scope of applications of cellulosics in biomass utilization and biomaterial production. The authors address three main topics (chemistry, analysis, and novel applications of cellulosic materials) and provide a panoramic snapshot of state-of-the-art cellulose research. Integrating nanoscience and applications in materials, energy, biotechnology, and more, the book appeals broadly to students and researchers in chemistry, materials, energy, and environmental science.
