Summary: Cellulose nanomaterials, including nanofibrillated cellulose and cellulose nanocrystals, have unique properties such as sustainability, biodegradability, and biocompatibility, making them attractive for a wide range of applications. Their aqueous suspension rheology allows for the creation of viscous suspensions with shear-thinning behavior. These properties make cellulose nanomaterials valuable rheological modifiers in fluid-based applications.

Summary: Cellulose nanomaterials have potential applications in the food and biomedical fields, but the potential hazards of oral exposure to these materials are not well-characterized. More toxicological studies, particularly on genotoxicity and long-term effects, are needed before wider use of these materials can be promoted.

Summary: By utilizing the percolated conductive network of cellulose nanocrystals-polyaniline (CNC-PANI) composites in a polyvinyl alcohol (PVA) matrix, a versatile nature skin-inspired composite film as a flexible strain biosensor was developed. The composite electronic skin exhibited robust mechanical strength, high sensitivity, and easy water-induced self-healing abilities. The 5% CNC-PANI composite film showed the best overall sensing property, indicating the potential of conductive nanofiller-based composite strain biosensors as an alternative to commercial synthetic sensors.

Summary: In this study, cellulose microfibers and cellulose nanocrystals with phosphoric groups on their surfaces were prepared by phosphorylation of cellulose extracted from Giant Reed plant. The phosphorylated samples showed differences in charge content and crystallinity depending on the phosphorous agent used. The phosphorylated microfibers and nanocrystals exhibited specific morphologies and thermal properties, suggesting potential new applications.

Summary: This study proposes a micro-assembly method to improve the photoluminescent properties of crystalline cellulose nanocrystals (CNCs) by organizing them within a sub-micrometer-sized metal-organic framework and coating with TiO2. The TiO2 coating prevents CNC assembly breakdown and allows information to be revealed using screenprinted labels for anti-counterfeiting purposes.

Summary: Cellulose nanomaterials (CNMs) have the potential to be used as food additives or in food packaging, but their safety when ingested by humans is still unknown. This study found that some CNMs can disrupt intestinal barrier function and have cytotoxic effects on cells. The size and shape of the particles also play a role in their effects.

Summary: This article reviews recent progress in the development of porous materials based on cellulose nanostructures found in plants and other resources. The potential uses of nanocellulose, a plant-based material, in regenerative medicine are discussed, considering its chemistry, shape, and structural control. Strategies for material synthesis and adjusting material architecture (including three-dimensional printing, freeze-casted porous materials, and electrospinning) for various applications in tissue engineering, artificial organs, controlled drug delivery, and wound healing systems are reviewed. The structure-property-function relationships of nanocellulose-based porous materials are mapped, and the steps required to translate innovation from the lab to industry, including regulatory aspects and market pull, are examined. The article concludes with a critical review of the key challenges and opportunities in this emerging field.

Summary: The study focused on integrating cellulose nanocrystals (CNC) with copper-based ink on a polymer substrate, and using a sintering process based on intense pulsed light in an argon atmosphere to improve electrical conductivity and enhance resistance to fatigue failures caused by bending and stretching. The presence of CNC not only improved electrical conductivity but also reduced damage due to mechanical stress, making it a promising solution for improving the performance of copper nanopowder-based inks.

Summary: This study aimed to extract cellulose nanocrystals from quinoa straws through acid hydrolysis and evaluate their physicochemical properties. The optimal extraction conditions were determined as 60% sulfuric acid concentration, 50 degrees C reaction temperature, and 130 min reaction time, resulting in a maximum yield of 36.58%. The obtained QCNCs exhibited a rod-like shape with an average length of 190.29 nm, average width of 20.34 nm, high crystallinity (83.47%), good water dispersibility (Zeta potential =-31.34 mV), and thermal stability above 200 degrees C. The addition of 4-6 wt% QCNCs significantly improved the properties of high-amylose corn starch films. This study contributes to enhancing the economic value of quinoa straw and provides evidence for the potential application of QCNCs in starch-based composite films.

Summary: A programmable spray coating technique is introduced to enhance the multifunctionality and structural properties of carbon fiber composites. The shape of the deposited patterns can regulate interface formation, damage containment, and electrical-thermal conductivity, improving the overall performance of the composites. This approach eliminates the trade-off between properties that are considered paradoxical in conventional manufacturing.

Summary: Currently, a significant amount of food, approximately 30-50%, is wasted from post-harvesting to consumer usage. This research focuses on extracting cellulose from leftover orange peel and converting it into cellulose nanocrystals for functionalizing biobased packaging materials. The addition of cellulose nanocrystals improved the films' mechanical and barrier properties, while the inclusion of lauroyl arginate ethyl enhanced their flexibility and biocidal efficacy against bacterial pathogens.
