his book is part of the Wiley Series in Renewable Resources. It is an excellent introduction for students, researchers, and newcomers in the field of cellulose material chemistry, properties, and applications as a renewable and green resource. The text introduces readers to the structure, extraction, properties, and applications of the different types of cellulosic nanomaterials processing techniques. The book thoroughly explains the distinct chemistry of cellulose, including the different extraction processing techniques. It provides researchers with comprehensive knowledge supported with illustrations and includes tables of useful materials properties, in particular, mechanical properties. The references are adequate and up to date, and the text is written from the combined perspective of physical chemistry and materials engineering. The first chapter introduces the historical background of cellulose biopolymer

and hierarchical materials as green nanostructured materials that can replace different types of toxic nanostructured materials. The second chapter deals with physical, chemical, anisotropic, and mechanical properties of cellulose fibers and their relationships with structure and morphology. Chapter 3 delves into the fundamentals of hydrolytic extraction of cellulose nanocrystals and their stability. It also introduces reaction kinetics, yield optimization, reproducibility, and different conditions of the extraction processes. Chapter 4 details different characterization techniques, such as x-ray diffraction, ultraviolet spectroscopy, and nuclear magnetic resonance of cellulose crystalline solids and the relationship between their properties and structure. The chapter also describes the effects of different conditions and/or parameters on the morphology and microstructure of cellulose nanocrystals, such as the effects of sonication, solution

his is a book for crystal chemistry lovers. It is beautifully produced and is comprised of seven chapters. The first four are a useful introduction to the topic, and the remaining three delve into different ways of looking at structures, with an emphasis on the concepts of the author and some colleagues (in particular, Michael O’Keeffe, Bruce Hyde, and Sten

Andersson). All of the figures are available on the Internet if you show proof of purchase of the book. Chapter 1 begins with the polyhedral approach to structure building, which is familiar to chemistry undergraduates. This leads to building blocks, cubes, and unit cells. The chapter clearly explains simple cubes, body-centered cubes, face-centered

concentration, temperature, surface charge, and ionic strength of their suspensions. Chapter 5 covers the different applications of cellulose nanocrystals as
