Summary: There has been a growing number of studies on developing hydroxyapatite (HA) for use in biocomposites. This study explores the use of HA derived from green mussel shells in biocomposites and investigates the effect of composition on mechanical properties and degradation rate. The findings suggest that increasing the HA and PLA content improves the mechanical properties of the biocomposites but also increases the degradation rate.

Summary: Biodegradable metals with degradation rate proportional to tissue repair process have become new generation orthopedic implants. Magnesium-based composites are attractive candidates for temporary implants due to their biodegradability and elastic modulus similar to bone. However, high corrosion rates in physiological environment have caused uncontrolled degradation. Mg/HA composite samples were fabricated and coated with PCL and PCL/HA nanofibers. The coating process involved electrospinning and HNO3 treatment that controlled the degradation and preserved mechanical integrity.

Summary: This research study investigates the effects of hydroxyapatite (HA) particle size and content on the processability, microstructure, and mechanical properties of Ti-6Al-4V (Ti64)-HA composites fabricated through laser powder bed fusion (LPBF). Results show that the addition of HA powder slightly increases the reflectance of Ti64-HA composite powders. The processability of composite powders strongly depends on the content of HA, with crack-free parts observed for composites containing 1 wt%HA. Furthermore, the incorporation of 1 and 2.5 wt%HA significantly improves the nanohardness and yield strength of Ti64.

Summary: This study proposes a strategy to balance the mechanical and biological properties of HA/PEEK scaffolds by regulating the inner crystallinity and HA mixing ratio. The modified 20%HA/PEEK scaffolds with low crystallinity achieved the desired strength and elasticity, and exhibited characteristics that promote the proliferation, migration, and osteogenic differentiation of bone marrow mesenchymal stem cells. The results of in vivo experiments showed that the 20%HA/PEEK scaffold with low crystallinity could withstand local complex force in the defect area and integrate well with natural bone tissue, making it a potential material for practical versatile hard tissue engineering scaffold.

Summary: The purpose of this study was to evaluate the biaxial strength of bi-layered PEEK restorations with different veneering materials and thickness ratios before and after aging. The results showed that the choice of veneering material and the thickness ratio between the core and veneering material had a significant effect on the flexural strength of the restorations. Thermocycling also negatively impacted the flexural strength. The study concluded that conventionally layered composite with a core to veneering thickness ratio of 1:0.5 is the best choice for veneering PEEK cores.

Summary: The present research investigated the mechanical properties of wood flour reinforced polyethylene polymer composites with varying wood flour size, aspect ratios, and mold injection temperature. Results showed that reducing the wood flour size decreased the tensile strength and modulus, flexural strength and impact energy, while increasing the flexural modulus. Additionally, increasing the injection molding temperature decreased the tensile strength and modulus, impact energy, while increasing the flexural strength and modulus. Thus, optimizing the injection molding temperature can improve the mechanical properties of the composite.

The results showed significant improvements in piezoelectric response and sensitivity compared to pure PVDF films. First-principles calculation and finite element analysis confirmed the effect of SiC nanoparticles on the composite film.

Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: The bainite transformation in medium Mn steels has been experimentally and theoretically studied, and it has been found that the transformation kinetics is slow. However, the introduction of dislocations can significantly accelerate the transformation rate. A new "carbon depletion mechanism" is proposed to explain the role of dislocations in the acceleration of bainite transformation, and a physical model is developed to quantitatively understand the kinetics of bainite transformation.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
