Summary: In this study, a high-performance structural material derived from natural bamboo is developed, which exhibits superior mechanical and thermal properties. By introducing surface charge and layer-by-layer assembly of bamboo cellulose fibers, the material overcomes the limitations of natural size and anisotropy of bamboo. It possesses high flexural strength, low coefficient of thermal expansion, high thermal stability, and excellent fire resistance. With its excellent properties and efficient manufacturing process, it becomes a powerful plastic alternative for furniture, construction, and automotive industries.

Summary: This study examines the potential of using biomass recycled aggregates developed from coconut shells to replace aggregates in structural concrete. The experimental results show that using synthetic biomass recycled aggregates can achieve comparable mechanical properties, shrinkage properties, thermal conductivity, and microstructure to natural aggregates in concrete. In addition, crushed coconut shell aggregate concrete and synthetic biomass recycled aggregate concrete show significant improvements in energy saving potential.

Summary: Manufacturing biomass aerogels from ammonium alginate and phytic acid results in aerogels with high mechanical modulus, specific modulus, flame retardancy, and low thermal conductivity. These aerogels also exhibit excellent thermal insulation performance and biodegradability, providing a new strategy for environmentally safe thermal insulation materials.

Summary: Two series of alpha-1,3-glucan with branched and linear mixed ester side chains were synthesized as biomass-based thermoplastic resins, showing improved flexibility with increased hexanoate substitution. The mixed ester method effectively controlled the physical properties of alpha-1,3-glucan esters, making them promising for transparent and flexible films with high thermal stability for electric devices of designability.

Summary: Despite the current problems of low mechanical properties, strong hydrophilicity, and poor thermal resistance in biomass composites, this study successfully fabricated starch-based fiber-reinforced composites with foam structures for the first time. The addition of aluminum hydroxide (ATH) improved the microstructure and material composition, resulting in an increase of up to 37% in ultimate tensile strength. Molecular dynamic simulations further confirmed the positive effects of ATH on the tensile properties at an atomic level. In addition, the addition of ATH also improved the compressive properties, water resistance, and thermal stability of the composites, making them potential candidates to replace traditional packaging materials.

Summary: The study investigates the thermoelectric performance of invar 36, a ductile material with low coefficient of thermal expansion. The results show that invar 36 exhibits a negative Seebeck coefficient and comparable power factor to some thermoelectric materials, but significantly lower figure of merit. However, it has excellent mechanical properties and significantly lower CTE and higher thermal shock resistance, which make it potentially interesting for applications where durability is important.

Summary: Despite regulations, plastic microbeads are still widely used in PCCPs, causing microplastic pollution. This study proposes a sustainable alternative by producing microbeads from biomass solutions and anti-solvent precipitation. By adjusting biomass source, concentration, and polymerization, as well as extrusion and precipitation conditions, the resulting microbeads have similar properties to commercial plastic microbeads. The addition of lignin improves processability but results in stiffer microbeads.

Summary: Olive tree prunings can be used to produce particleboards as an alternative to conventional wood, with the potential to reduce formaldehyde emissions and improve indoor air quality. However, the substitution level should be carefully considered to balance mechanical properties.

Summary: The study focused on the effects of substituting the B cation in A(3)BO(7) ceramics on their thermal physical properties by applying a large mass difference. The results showed that Y-3(Nb1-xTax)O-7 ceramics exhibited low thermal conductivity and distorted crystal structure due to the mass difference, but substitution with Ta5+ enhanced sintering resistance, leading to improved thermal-insulating performance. The ceramics also showed promising coefficients of thermal expansion, suggesting their potential as new thermal barrier materials.

Summary: This study investigated the effect of cooling rates on the crystallization, thermomechanical, and fracture properties of PPS and CF/PPS. The results showed that slow cooling rates led to high crystallinity, increasing the elastic modulus and yield stress but decreasing strength and fracture toughness. In neat resin, a transition from brittle to ductile fractures occurred between 1 and 10 degrees C/min, significantly increasing fracture toughness. However, CF/PPS fracture toughness was less affected by cooling rate and significantly lower than that of neat PPS due to weak fiber/matrix bonding.

Summary: The aim of this research was to investigate the impact of fertilising with different doses of ash from biomass combustion on the morphology and mechanical properties of potato tubers. The findings showed that using a certain dose of ash from biomass combustion can improve tuber yield and resistance to mechanical damage. Ash from biomass combustion can be used as an alternative to conventional mineral fertilizers and contribute to sustainable agricultural practices.

Summary: This study investigates the microstructure and thermomechanical properties of Al11Ce3, an intermetallic compound that strengthens Al-Ce based eutectic alloys. The results show that Al11Ce3 is hard and brittle, with coarse and elongated grains and internal twins. The thermal expansion coefficient and oxidation kinetics of Al11Ce3 vary with temperature. At 500 degrees C, Al11Ce3 exhibits extensive plastic creep deformation. The study also found that the creep resistance of Al11Ce3 at 500 degrees C is similar to that of L1(2)-Al3Sc.

Summary: The research conducted a two stage method of transesterification/esterification and polycondensation to synthesize three biobased poly(hexamethylene 2,5-furandicarboxylate-co-adipate) copolyesters with low hexamethylene adipate (HA) units. The copolyesters exhibited good thermal stability, with thermal properties decreasing as the content of HA units increased. Increased HA units resulted in higher elongation at break and a relatively high melting point temperature for the copolyesters.
