Nanocelluloses (NCs) are bio-based nano-structured products that open up new solutions for natural material sciences. In recent years, many research groups and industries have been extensively working on ground-breaking innovations for the characterization and production of cellulose nanofibers (CNF), cellulose nanocrystals (CNC), and bacterial nanocellulose (BNC), making possible new potential applications in many different areas, such as composites, paper and board, packaging, paints and coatings, oil and gas, personal care, cosmetics, UV filters, medical implants, antibacterial materials, drug delivery, 3D printing, inks, food stabilizers, functional food ingredients, food and beverages, super-absorbents, environmental and wastewater treatments, metal removal, membrane filtration, CO2 adsorption, agriculture, insulators, fire retardants, batteries, biosensors, flexible electronics, energy storage, cement industry, textiles, sports footwear, plastics, rheology modifiers, etc.. In summary, NCs open up an endless number of applications.
This Special Issue aims to cover a broad range of NCs applications in the industry. Full papers, short communications, and reviews are welcome.
Submissions with outstanding contributions to accelerate the generation of new knowledge and to make significant advances in the industrial use of NCs are especially welcome.

Abstract: Cellulose nanocrystals (CNCs) have been used as a new generation of nanoparticles in different fields. While CNCs have outstanding performance (e.g., in terms of mechanical properties), their production mainly relies on chemical routes that make use of harsh reagents. Finding cleaner alternatives is therefore of great interest in light of the increasing attention to green chemistry approaches. In this work, we have evaluated the obtainment of cellulose nanocrystals (CNCs) via enzymatic hydrolysis. To this scope, bacterial cellulose (BC) produced by Komagataeibacter sucrofermentans was used. The hydrolytic effect of two enzymes (endo-1,4-β-glucanases and cellulase from Trichoderma reesei) with different hydrolytic activity was compared by means of turbidity experiments over a period of 145 h. Bacterial cellulose nanocrystals (BCNCs) arising from the two different enzymes were compared in terms of size and morphology by TEM and AFM. BCNCs were used as a reinforcement of biopolymer coatings deposited on PET for the food packaging industry. The positive effect arising from the addition of BCNCs in the main pullulan coating was evaluated in terms of oxygen barrier properties. Noticeably, the oxygen transmission rate (OTR) of the pullulan/BCNCs-coated PET film was below 1 mL/m-2 24h-1, demonstrating the potential of BCNCs for the generation of high oxygen barrier coatings.
