Summary: The study showed that aramid fibers increased the energy absorption of both matrix materials, while carbon and glass fiber fabrics only increased the energy absorption of one matrix material. All reinforcement materials increased the maximum strain values of one matrix, but did not affect the maximum CAI strength values of the other matrix.

Summary: The study found that the addition of maleic anhydride (MA) as a compatibilizer did not delay hydrothermal aging of the biocomposites in an acid medium. Biocomposites reinforced with olive husk flour (OHF) were highly sensitive to prolonged exposure under such conditions. The thermal properties of PHBV/OHF biocomposites exhibited significant changes due to the hydrophilic nature of the flour.

Summary: By adding low-cost olive pits flour (OPF) and precipitated bio-calcium carbonate (PBCC) into PVC, the stability and rigidity of the composites can be improved, along with enhancing the filler restriction effect on the polymer chains. Additionally, the smart distribution of PBCC particles can enhance the mechanical properties of the composite materials.

Summary: This study explores the possibility of developing a new class of hybrid biocomposites using wood flour and rice husk as environmentally friendly additives to PLA. The results show that the addition of natural waste particles significantly improves the mechanical properties of the material but decreases its impact strength and tensile strength. Limited interfacial adhesion between the components is observed, and the particles act as nucleating agents, increasing the overall crystallinity of the material.

Summary: This study aimed to produce ecological composites using biopolyethylene (BioPE) with macaiba shell (MS), polyethylene-graft-maleic anhydride (PE-g-MA) and polyethylene-graft-acrylic acid (PE-g-AA) as compatibilizers, as well as macaiba almond oil as a plasticizing agent. The addition of MS caused a reduction in impact strength and elongation at break, but improved stiffness and heat deflection temperature. The PE-g-MA and PE-g-AA compatibilizers improved the impact strength of the composites, suggesting increased interactions between the phases. The degree of crystallinity increased, indicating that the MS acted as a nucleating agent. The addition of macaiba oil increased the impact strength, but decreased the elastic modulus, tensile strength, and degree of crystallinity. PE-g-MA was more effective in improving the mechanical properties of the composites. The reuse of MS is feasible for the production of sustainable composites.

Summary: In this study, activated PLA/olive wood flour (OWF) composite films with different wood flour contents were prepared and tested for antimicrobial activity. The properties of OWF and cinnamon essential oil (CEO) were examined, and the films were tested for mechanical strength and antimicrobial activity against fungi and bacteria. The combined use of OWF and CEO showed synergistic antifungal properties. The films have potential applications in cereal packaging.

Summary: This study investigated the effects of maleic anhydride-grafted polypropylene (MA-g-PP) loading on the mechanical and physical properties of polypropylene/glass spheres/montmorillonite nanoclay (PP/HGS/MMT) composites. Results showed that increasing MA-g-PP content increased the elastic modulus and tensile strength, but decreased impact resistance, elongation at break, density, and hardness. The structure and chemical bonds of the composites were also studied.

Summary: This study aimed to improve the compatibility and mechanical properties of polypropylene/olive wood flour (OWF) composites by using different treatment methods. Results showed that silane and heat treatments enhanced the thermal stability of OWF and heat treatment introduced higher toughness in the composites.

Summary: The study investigated the genetic relationships among 41 olive genotypes using SSR markers, revealing high genetic variation among Azerbaijani olive genotypes and their distinctness from Turkish olive cultivars, suggesting the possibility of importation from different countries. The diverse olive genotypes identified could be valuable for the development of new olive varieties in Azerbaijan and could enhance future breeding programs between the two countries.

Summary: This study aimed to investigate BioPE/WP composites compatibilized with PE-g-MA and processed with OM. The addition of 30% WP improved mechanical properties and HDT compared to neat BioPE, and further enhancement was observed with 10% PE-g-MA. Macaiba oil reduced torque, improved processability, decreased water absorption, and enhanced impact strength when incorporated into the composites. SEM analysis showed improved interfacial adhesion with the addition of PE-g-MA and macaiba oil.

Summary: The flame retardancy and mechanical properties of multilayered wood-polymer composites were studied in this paper. The addition of boric acid improved the fire retardancy but decreased the flexural strength. The presence of PC cap layers suppressed combustion and increased the flexural strength of the composites.

Summary: The study investigated the hygrothermal aging of neat PHBV and PHBV/C30B at high temperature and humidity conditions. Results showed that PHBV bionanocomposite exhibited better resistance towards hygrothermal aging, but suffered from reduced crystallinity, melting temperature, thermal stability, and altered mechanical and viscoelastic properties under such conditions.

Summary: The tensile and viscoelastic properties of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) are improved by adding zinc oxide nanoparticles, with the degree of improvement depending on the content of zinc oxide nanoparticles. However, at 3 wt%, the flexibility and toughness of the material decrease.

Summary: The development of new bio-based and biodegradable composites with enhanced performances is a efficient route to achieve a sustainable materials production. Biocomposite materials based on PHBHHx reinforced with Agave leaves fibers (ALF) were prepared by melt compounding at various filler content ratios, and the effect of ALF content on the material properties was evaluated based on thermal stability, tensile, and surface properties. The results show that the addition of ALF leads to reinforcement effect on PHBHHx, which is more pronounced at 30 wt%.

Summary: The objective of this work is to investigate the effect of using olive husk flour (OHF) as a biofiller on the marine degradation of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) biocomposites. The results show that the presence of OHF promotes the hydrolytic degradation of PHBV, especially at 40 degrees C. Additionally, the degraded samples exhibit eroded and cracked surfaces.
