Summary: This study aims to investigate the influence of parameters such as Na/Al molar ratio, water content, and pressure load on the physical, microstructural, and durability properties of one-part pressed geopolymers. The results show that these parameters play a key role in controlling the properties of geopolymers and optimizing them can lead to geopolymers suitable for microfiltration flat membrane support. The best performances in terms of durability are obtained when using the highest pressure load (20 MPa) and water content (15%).

Summary: Electron-induced luminescence was observed in a variety of materials used in biological electron microscopy, with similar patterns of intensity rise, spectral red-shifting, and bleaching upon increasing electron fluence. The luminescent profiles shifted to higher fluences with increased landing energies, indicating a predictable and tunable electron-induced luminescence in polymer media. These findings suggest the potential for turning polymers into luminescent nanostructures or fluorescently visualizing (micro)plastics.

Summary: In this study, biobased novolacs phenol-formaldehyde (BNPF) resins were developed by partially replacing petroleum-derived phenol and formaldehyde with lignin derived from kraft biorefinery and modified kraft biorefinery-derived lignin, respectively. The lignin was chemically modified through the periodate oxidation process, and a series of BNPF resins were synthesized by replacing phenol and formaldehyde with lignin and oxidized lignin. The NPF resins exhibited the formation of methylene linkages in the phenolic rings. The bonding performance tests showed that BNPF resin adhesives have high adhesion strengths (>0.7 MPa). This research provides a promising perspective for utilizing natural polymers such as lignin for the synthesis of biobased wood adhesives.

Summary: The self-assembling films were used on pine wood substrates to alter surface wettability, with monodisperse polystyrene spheres deposited onto the substrate via dip coating. The resulting film had a polycrystalline FCC-like structure with typical domain sizes of 5-15 single spheres. Functionalization of this self-assembled coating through O-2 plasma treatment introduced hydroxyl and carbonyl groups, resulting in superhydrophilic behavior.

Summary: Different formulations of phenolic resins based on lignin and tannins, with the addition of inorganic nanoparticles, were studied as biobased fireproofing coatings for wood. The structures and thermal properties of the coatings were characterized, and their fireproofing performance was evaluated against commercial coatings, showing significant reduction in heat release, improved wood integrity protection, and delayed flame propagation. The biobased coatings performed better on beechwood compared to maritime pinewood, with formulations R-A and R-B achieving results comparable to the commercial fireproofing coatings.

Summary: Although furfurylation improves the dimensional stability, hardness, and biodegradation resistance of wood and bamboo, its effects on weathering resistance are still not clear. This study found that furfurylation improved the stability of photo-discolouration in poplar wood and bamboo, but weathering caused degradation of lignin and oxidation of poly(furfuryl alcohol). Furfurylated poplar wood showed higher stability of photo-degradation compared to furfurylated bamboo.

Summary: Cross-linking modification using polycarboxylic acid improves dimensional stability and decay resistance, but increases brittleness and rigidity in wood. Introducing polyols into the cross-linking network enhances flexibility, but the relationship between strength and reaction is limited in research. This study modified poplar wood by cross-linking with BTCA and esterifying with polyols (SO and SU). The physical and mechanical properties, effect mechanism, and microstructure were investigated. The findings showed a cross-linked structure with increased ester bonds and ample polymer filling in the lumens, and SU had lower leachability. The reduction in modulus of rupture caused by BTCA treatment could be compensated by reducing the degree of cross-linking, especially with SO-BTCA treatment. The modulus of elasticity of BTCA treated wood was slightly affected by the addition of polyols.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
