Summary: There is increasing pressure to reduce the use of plastics and demand for clean, renewable, recyclable/biodegradable packaging products in the packaging industry. Molded fiber/pulp products are gaining attention due to their green/sustainable advantages, using plant-based and/or recycled fibers as raw materials. Many companies have switched from plastics to molded fiber products, leading to significant effects on the packaging industry. This paper provides an overview of the concept of molded pulp products and summarizes different types of molded fiber products in terms of natural fiber sources, manufacturing processes, current and emerging applications, and environmental sustainability.

Summary: This study explores the development of thick carbon electrodes derived from basswood and their application in high energy density supercapacitors. The anisotropic structural carbon electrodes derived from wood exhibit different transfer kinetics of the electrolyte, which significantly impacts the electrochemical performance, especially at high current density. The results show that the cross-sectional wood-derived carbon with high specific surface area contributes to excellent electrochemical performance, attributed to its hierarchical porous structure that allows easy access for the electrolytes even at high current density. This work provides insights into the dynamic behaviors of electrolyte in different wood sections and can be extended to other wood species and wood-like structures for energy storage applications.

Summary: In this study, hinokitiol-grafted-chitosan (HTCS) was prepared and used as an antibacterial agent for cotton fabric treatment. The results showed that HTCS had a lower minimum inhibitory concentration (MIC) and higher antibacterial rate against Escherichia coli and Staphylococcus aureus compared to chitosan (CS) and hinokitiol (HT) alone. The HTCS-treated cotton fabric maintained good antibacterial properties even after multiple washing cycles.

Summary: This study found that using AFRP wrapping can effectively improve the bearing capacity, stiffness, and ductility of short LBL columns, which will have a positive impact on the overall performance of structures. Under cyclic loading, the stress-strain curves of the specimens showed lower values compared to monotonic loading.

Summary: This paper reports the effect of doping sodium iodide (NaI) salt into a polymer blend matrix on the properties of the resulting solid polymer electrolyte (SPE) films. The inclusion of NaI decreased the crystallinity and increased the conductivity of the SPE. The highest conducting sample exhibited good mechanical strength and suitability for energy storage devices.

Summary: The structural arrangement of polymers in the cell wall of wood, particularly the roles of glucomannan and xylan in the secondary cell wall, is still not fully understood. Recent studies have shown a close association of xylan with cellulose microfibrils in softwoods. Various techniques have been used to examine these findings, and the overall results strongly support the association of both glucomannan and xylan with cellulose microfibrils.

Summary: This study proposes a new dynamic multiblock partial least squares (DMBPLS) method for extracting time-varying information in large-scale papermaking wastewater treatment processes. By introducing augmented matrices, this method handles the dynamic characteristics of data, reduces the time delay of fault detection, and enhances the interpretability of the model. Compared to other models, DMBPLS achieves superior fault detection results.

Summary: Cellulosic materials have gained attention due to their abundance, renewability, and excellent physicochemical properties, while research on nanofibers has been increasing for a wide range of applications. Electrospinning is a promising technique for producing fibers with improved characteristics, although limitations such as poor solubility and inability to melt exist for cellulose and its derivatives. Recent research has focused on exploring the potential applications and processing details of electrospun nanofibers using cellulose and its derivatives as feedstock.

Summary: The hydrothermal transformation of microcrystalline cellulose derived from birch wood under the influence of Al2O3-B2O3 mixed oxide solid acid catalysts was studied. The results showed that the catalysts exhibited high activity for the conversion of glucose and 5-hydroxymethylfurfural at 180 degrees C. However, the accumulation of unhydrolyzed cellooligosaccharides in the reaction solution caused catalyst deactivation. The catalysts could be reused after washing with water and still maintained good catalytic performance.

Summary: Wood science encompasses the formation, composition, and properties of wood, including its chemical, biological, and physical-mechanical aspects. In-depth knowledge of wood is crucial for wood processing, wood-based material production, and the utilization of wood and wood-based materials in construction and furniture. Understanding wood chemistry, biology, and physical-mechanical properties is essential for technological processes and product development.

Summary: The wood-water interactions of modified beech wood were studied, and the results showed that the extent of interaction depended on the thermal modification temperature and type of chemical modification. Thermally modified wood had lower water vapour absorption, with more severe treatments resulting in greater reduction. Acetylation had the greatest impact on water vapour absorption and dimensional stability. Modified wood also exhibited slower and gradual swelling compared to the reference specimens.
