Summary: The study reveals that microwave power has a direct impact on the characteristics of ZnO nanostructures, allowing for morphology changes by adjusting microwave power. The fast growth along the high energy polar faces of ZnO is the reason for the formation of one dimensional ZnO structures, while the formation of hollow ZnO rods is due to further etching/material removal from the tip of the rods under high microwave power conditions at long growth durations.

Summary: SiO2/FeCoNiSi0.25 core-shell high-entropy alloys (HEAs) with nanotwinned structures exhibit good magnetic properties and bending ductility. The crystallization phase of the HEAs is a solid solution phase with a deformed twin face-centered cubic structure instead of a brittle intermetallic phase. Additionally, the HEAs have high yield strength and plastic strain. The magnetic intensity characteristics of the FeCoNiSi0.25 core-shell HEA outperform those of SiO2-shell-free HEAs. The improvement in mechanical properties and magnetic sensitivity can be attributed to the materials' strengthening and toughening by nanotwinned structures, as well as the regulation of magnetic structure by grain boundaries and nanotwinned structures. These findings are instrumental in preparing HEAs with high magnetic sensitivity and an excellent combination of mechanical properties.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
