Summary: The study demonstrates that the pre-treatment of nanofibers has a significant impact on the flow and shear behavior of lubricating oleogels. Oleogel based on chemically-prepared nanofibers is more sensitive to temperature and large shear deformations compared to oleogel based on mechanically-prepared nanofibers.

Summary: This study investigates the thermo-mechanical behavior of densified veneer wood (DVW) for cryogenic applications. Mechanical tests were performed at different temperature levels and the results showed that compression moduli and brittleness increase with decreasing temperature. The compressive strength initially increased with decreasing temperature until about -30 degrees C and then slightly decreased. The specific heat capacity showed a linear dependency on temperature below +20 degrees C, but above this temperature, a non-linear increase was observed due to evaporation of bound water. Additionally, a technique for molding DVW boards in a different direction to reduce waste material was presented.

Summary: Hydrophobic lignin containing nanofibril (LCNF)/poly (vinyl alcohol) (PVA) aerogels were prepared and showed outstanding physical properties, high hydrophobicity, absorption capacity for various oils and organic solvents, and the ability to separate emulsified water/oil mixtures. The aerogel also demonstrated good reusability and was fabricated using a sustainable technique.

Summary: In this study, electrode materials with high electrochemical performance were prepared using activated carbon derived from black liquor. The optimal conditions for preparation were determined to be 500 degrees C for carbonization temperature and 700 degrees C for activation temperature. The resulting activated carbon showed a specific capacitance of 389 F/g, an energy density of 22.2 Wh/kg, and a specific surface area of 2147.77 m2/g. One notable advantage of the activated carbon prepared by evaporating the black liquor is its retention of hetero-atoms, such as S, which leads to higher capacitance.

Summary: This paper describes the development and characterisation of wood-filled polylactic acid (PLA) composite filaments for 3D printing. The results indicate the positive effects of thermal modification of wood particles on the properties of filaments and 3D-printed parts. However, further optimization of particle preparation and extrusion parameters is needed to obtain quality filaments with this size of wood particles.

Summary: This study investigates the effect of wood fibre reinforcement on the acoustic properties of 3D printed poly lactic acid samples with varying perforation structures. The results demonstrate that the addition of wood fibres significantly improves the sound transmission loss characteristics of the samples and shifts the sound absorption peaks to lower frequencies. This material can be used for acoustic insulation in structural and transportation applications.

Summary: In the apparel industry, recycling cutting waste to produce yarn is an important but underexplored area. This study aims to utilize a higher proportion of recovered cotton fibers with virgin cotton fibers in rotor spinning to manufacture recycled yarn and analyze its quality. The results show that the 60:40 blend of recycled and virgin fibers has better uniformity and less imperfection, while the 70:30 blend is more cost-effective and allows for better material recovery.

Summary: In this study, composite energetic cellulose core-shell materials with improved hydrophilic and adiabatic safety were successfully prepared by modifying nitrate glycerol ether cellulose (NGEC) with polydopamine (PDA). The PDA coating did not alter the structure of NGEC, but significantly improved its hydrophilicity.

Summary: This study confirmed that the loss tangent obtained from the longitudinal vibration of a wood log increases with the apparent density difference between sapwood and heartwood, due to moisture content difference. The study also found that the shear strain energy increases with the apparent density difference, leading to an increase in the loss tangent. This research provides insight into the relationship between apparent density difference and loss tangent in wood logs during longitudinal vibration.

Summary: The dynamic adsorption and desorption behaviors of rosin colloids onto and from CNFs and TOCNFs in aqueous media were investigated using QCM-D measurements. The effects of maleic anhydride modification, anionic surfactant, and Alum addition on the adsorption were studied. The results showed that maleic anhydride modification contributed to particle size reduction, an increase in Tg, and enhanced stability, while using an anionic surfactant increased the particle size and ionicity. The adsorption of rosin colloids was affected by the surface charge of CNFs and the presence of Alum.

Summary: Moisture sorption and diffusion processes of plant fiber materials have a significant impact on their properties and product quality. This study utilized a multi-scale imaging approach to identify the heterogeneous structure of plant leaves and the impact of fiber structure and pore channels on water adsorption. The mechanisms of water adsorption, osmotic diffusion, and hygroscopic swelling were illustrated. The effects of temperature and water activity on water diffusion and the water-blocking effect of the waxy layer interface were also investigated.
