Summary: This study aimed to understand the role of hydroxyl accessibility in wood-water interaction during humidity-dependent changes in moisture content. The results showed that changes in hydroxyl accessibility were not the driving force for these changes, although a slow re-protonation rate at low relative humidity was observed.

Summary: This study found that supercritical carbon dioxide (ScCO2) is an efficient drying medium for various materials, such as wood, due to its good solubility and mass transfer properties. The drying rate is mainly influenced by pressure and temperature, with pressure having a more significant effect. The efficiency of dewatering is not dependent on the sample length, and there are significant moisture content gradient differences along the wood in radial and tangential directions.

Summary: This paper presents a mathematical model for mold growth on wood using the logistic growth equation. The microscopic mold coverage fraction is employed to represent the development of mold on the material surface over time. The mold growth coefficient is estimated by simulating mold growth under constant environmental conditions and finding the best fit with the Finnish mold growth model. The model parameters are verified by comparing with experimental observations of mold growth and potential improvements are discussed.

Summary: The synergistic fermentation of Lactobacillus plantarum and Saccharomyces cerevisiae had an effect on the structural properties and aggregation behavior of gluten. The addition of different levels of wheat bran dietary fiber significantly influenced the aggregation behavior and secondary structure of gluten. Additionally, the thermal properties and water holding capacity of the dietary fiber played a major role in the changes observed in the overall gluten system.

Summary: Functional multiblock poly(ether-b-amide) (PEBA) copolymers with PA1212 as hard segments and Jeffamine ED-2003 as soft segments were successfully prepared via two-step melt polycondensation. Jeffamine ED-2003 improved the compatibility between polyamide and polyether compared to the traditional route using hydroxyl-terminated polyether. The structure and properties of the PEBA copolymers were characterized, and their potential applications as moisture responsive and antistatic agents were investigated.

Summary: This study described and compared the types of microplastics ingested by 274 fish from Thailand's eastern coast in 2020, finding a relatively high detection frequency compared to other regions in Thailand but relatively low compared to global standards. The dominant aspects found included PET, fiber, and black particles. The ingestion of microplastics by fish was influenced by the size, weight, and feeding behavior of the fish.

Summary: This study presents an orthotropic linear viscoelastic model to predict the time-dependent behavior of wood and composite materials. By calibrating the model against experimental creep data using an optimization approach, it shows that the model with time-dependent Poisson's ratios can effectively capture the time-dependent behavior of orthotropic materials, while caution should be taken when assuming constant Poisson's ratios.

Summary: In this study, a numerical multiscale model is used to investigate the effect of softwood's hierarchical structure on its macroscopic viscoelastic properties. The model is validated using creep behavior experiments on Norway spruce and Japanese cypress. The results demonstrate that by assuming that the variability is greater at the microstructural level, it is possible to predict the macroscopic creep behavior based solely on microstructural parameters, saving time and cost compared to characterizing creep in all material directions.
