Summary: Interests in the use of natural fibers as soil reinforcement are developing rapidly due to their cost effectiveness, high availability, and eco-friendliness. Research studies have shown that fiber inclusion increases the soil's moisture content, ductility, and dilation, while decreasing its maximum dry density and brittleness. The addition of fibers significantly improves the shear strength of the soil and the optimal fiber percentages for various fibers were determined.

Summary: The aim of this study was to investigate the water absorption behavior of bio composites reinforced with date palm fibers. RSM and ANOVA were used to analyze the impact of input variables (time, fiber content, and types of water) on the output variables (Mass of CDPF). The findings showed that bio composites with higher fiber content absorbed more water, and the diffusion coefficient ranged from 2.11 x 10-6mm2/s to 3.99 x 10-6mm2/s. The RSM model analysis confirmed the accuracy and reliability of the model, providing valuable information for engineers working with date palm fiber bio composites.

Summary: The thermal insulation capabilities of date palm fibre (DPF)-reinforced poly (beta-hydroxybutyrate) (PHB) composites were investigated. The results showed that the thermal conductivity of the composites increased with DPF content. The addition of DPF improved the thermal stability and compressive strength of the composites, but reduced their tensile properties. The water absorption of the composites was lower compared to conventional insulation materials.

Summary: In this study, Recycled Polymer (RP) composites were synthesized using compression molding process. Date Palm Fibers (DPF) were used as reinforcement materials with different lengths and weight ratios. The results showed that the hardness and impact of the composites increased with the increase of DPF weight ratio and length. The specimens with 10mm length and 20wt% weight ratio exhibited the highest creep resistance and tensile strength. The specimens with 2.5mm length and 5% weight ratio had the maximum strain due to the ductility of the plastic matrix.

Summary: Recent research on biodegradable magnesium-based implants has focused on improving their mechanical strength and controlling corrosion rate. The addition of nanoparticles to the magnesium matrix has been found to enhance its mechanical properties. However, little research has been done on the corrosion behavior of these new magnesium nanocomposites. This study investigates the electrochemical corrosion characteristics of these materials and finds that the nanocomposites exhibit slightly lower corrosion resistance compared to high-purity magnesium control. Both nanocomposites show the highest corrosion resistance at 1.0% volume fraction.

Summary: The topic of bioresorbable metals, particularly magnesium, for bone implant applications has gained significant attention. However, the fast degradation rate of magnesium-based materials limits their use in biomedical applications. There is a lack of understanding of the corrosion and corrosion-fatigue behavior of magnesium-based biocomposites. This paper reviews recent advances in this area and discusses factors influencing their biocompatibility, corrosion, fatigue, and corrosion-fatigue behavior.

Summary: Magnesium (Mg) has shown potential as a biodegradable material for orthopedic fixation devices due to its biocompatibility, but its low mechanical strength and fast corrosion in physiological environments are challenges. This study investigated the effect of adding boron nitride (BN) nanoparticles to Mg matrix on the mechanical properties, corrosion behavior, and biocompatibility of Mg-based nanocomposites. The results showed that the addition of BN nanoparticles significantly increased the microhardness, strength, and corrosion rates of the nanocomposites without impacting cytotoxicity. Further research is needed to understand the chemical behavior of nanocomposites in physiological environments and improve their viability in vivo.

Summary: The biodegradable nature of magnesium makes it an attractive material for biomedical applications when permanent retention is not recommended. However, its limited mechanical strength and fast corrosion rates hinder its use in bone fracture repair. This study focuses on assessing the corrosion behavior and biocompatibility of a newly developed Mg-Zn-Ca-Mn-based alloy and post-fabrication processes.
