Summary: An easy-fabricating, stable, and high-performance alkenyl succinic anhydride (ASA) paper-sizing emulsion stabilized by lauric arginate (LAE)/cellulose nanocrystals (CNCs) nanorods is developed in this study. The partial hydrophobization between ASA and LAE/CNCs adjusts the stability of the ASA-sizing emulsion. This novel emulsion shows small droplet size, high hydrolysis resistance, and a high paper-sizing degree for long-term storage.

Summary: A bio-nanocomposite material consisting of silk fibroin/polyvinyl alcohol as the matrix, TEMPO-oxidized bacterial cellulose nanofiber as the reinforcement, and silver nanoparticles as an antibacterial agent was synthesized. The mechanical and chemical properties of the material can be tailored by adjusting the content of bacterial cellulose nanofiber. The material also exhibits strong UV shielding property, antibacterial activities, and low silver leakage.

Summary: It is now understood that the bonding in crystalline cellulose involves hydrogen bonding, dispersion forces, and electrostatic attraction influenced by cellulose conformation. The surface chains of cellulose microfibrils have a different conformation and form different hydrogen bonds depending on their interaction with water, other microfibrils, or non-cellulosic polymers. The specific details of these surface interactions, especially in the presence of other polymers, are still uncertain and require further research.

Summary: Cellulose nanowhiskers with a diameter of 5-10 nm, high crystallinity of 74%, and C6 carboxylate groups were prepared from sisal fibers via selective oxidation and mechanical homogenization. The alkaline pretreatment using sodium hydroxide affected the crystalline type of the cellulose fibers. These versatile nanowhiskers are suitable for nanocomposites, tissue engineering, filtration, pharmaceutical, and optical industries.

Summary: An environmentally friendly bioadhesive derived from cottonseed meal waste and cellulose sawdust was successfully prepared in this study. It exhibited good bonding strength and thermal stability. The improvements in bonding strength and thermal stability were attributed to the strong chemical bonds and mechanical interlocking formed between the adhesive and the plywood substrates.

Summary: Lignocellulosic biomass, a renewable resource, has potential for biofuel production. Pretreatment of lignocellulose is crucial for biomass conversion, enhancing enzymatic hydrolysis and microbial fermentation. However, conventional pretreatment methods generate inhibitors that impede subsequent saccharification and fermentation. Therefore, effective detoxification methods are necessary to improve lignocellulosic bioconversion. This paper reviews lignocellulose pretreatment methods, inhibitors, their management, and explores the future prospects of lignocellulosic biomass for fuels.

Summary: This study investigated the characteristics of cellulose nanocrystals (CNCs) derived from pea pods and their reinforcement effect on chitosan (CS) polymer films. The addition of CNCs improved the UV and water barrier properties of CS films, slightly improved their thermal stability and tensile strength, and reduced their degradability. Therefore, the CS-CNC nanocomposite films could be potentially used as sustainable food packaging materials.
