Summary: Porous composite beams of HA/PLLA and HA/PLCL were developed using a combination of the template and freeze-drying methods. Their composition, mechanical properties, and fracture behavior were examined, showing significantly improved flexural mechanical properties compared to a pure HA beam. The addition of PLLA resulted in a higher modulus and fracture strength, while the addition of PLCL led to a higher fracture energy due to ductile elongation.

Summary: Although nanofillers contribute to improved physical characteristics and biological functionalities of polymer-based biomaterials, their dispersion in polymer matrices is still a challenging issue. Microfluidization, as a novel homogenization technique, has been used to homogenize polymer nanocomposites and minimize the undesired changes caused by traditional homogenization techniques. The results show that microfluidizer homogenization improves the physical characteristics in both nano and macroscale materials, leading to enhanced stability, uniform size distribution, good encapsulation efficiency, improved structural uniformity, and enhanced thermal and mechanical properties.

Summary: In this study, a novel composite biomaterial was processed using ECAP, which significantly homogenized the microstructure and improved the mechanical properties of the material. The refinement of second phases and the variation of grain orientation by ECAP were found to enhance the mechanical performance of the obtained composites. Furthermore, the ECAP method decreased texture density and activated more slip systems, leading to improved plasticity in the material.

Summary: In order to fully utilize black liquor from pulping and reduce its pollution impact, lignin-based epoxy resin composite films were made from black liquor lignin. Fourier transform infrared spectroscopy confirmed the successful synthesis of lignin-based phenolic amine (LPAA) and the LPAA acted as a curing agent for the prepared epoxy resin films (LPAAF). The LPAAF showed good dispersion of black liquor's inorganic chemicals and exhibited higher tensile strength (30 MPa) and thermal stability compared to films cured with traditional phenolic amine. Thus, LPAAF made from black liquor lignin represents a novel utilization of black liquor.

Summary: The limpet tooth is considered as the strongest material in nature, with a reported strength value of up to 6.5 GPa. The recent discovery of microscale auxeticity in the tooth's leading part provides a possible explanation for this extreme strength. Through micromechanical experiments, it is found that the hardness values obtained from nanoindentation are lower than the strength observed in micropillar compression tests. This unique behavior is attributed to local tensile strains during indentation, resulting from the microscale auxeticity, leading to microdamage in the auxetic regions of the tooth microstructure.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
