Nanocellulose is a term referring to nano-structured cellulose. This may be either cellulose nanocrystal (CNC or NCC), cellulose nanofibers (CNF) also called microfibrillated cellulose (MFC), or bacterial nanocellulose, which refers to nano-structured cellulose produced by bacteria. It can also be obtained from native fibers by an acid hydrolysis, giving rise to highly crystalline and rigid nanoparticles which are shorter (100s to 1000 nanometers) than the nanofibrils obtained through homogenization, microfluiodization or grinding routes. The resulting material is known as cellulose nanocrystal (CNC).

In the present book, sixteen typical literatures about Nanocellulose published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on cellulose nanocrystal, nanoengineering cellulose nanofibers, microfibrillated cellulose, bacterial nanocellulose, etc. We hope this book can demonstrate advances in nanocellulose as well as give references to the researchers, students and other related people.
