Summary: Diamond/aluminum composites were fabricated using gas pressure infiltration method with different raw materials. The effect of interfacial phase type and size on thermal conductivity was investigated, as well as the evolution of microstructure and properties under temperature shock environment. The results showed that the introduction of W and WC coatings could inhibit the formation of interfacial phase Al4C3. However, the generation of amorphous carbon in WC-coated diamond/aluminum composite led to a weak interface bonding and a decrease in thermal conductivity. The W-coated diamond/aluminum composite exhibited the optimal thermal properties after 1000 cycles of temperature shock treatment, with improved performance stability and high thermal conductivity.

Summary: A novel metal matrix composite (MMC) with Mg matrix reinforced by Didymosphenia geminata frustules (a type of algae with siliceous shells) was studied. The addition of 1% of the filler improved the corrosion resistance of Mg, without affecting cell morphology. Adding 5% of the filler did not have cytotoxic effects but increased the corrosion rate. Adding more than 5% of the filler resulted in significant corrosion and cytotoxicity. The addition of the filler also affected the thermal and mechanical properties of the material.

Summary: In this study, a comparison of the non-isothermal crystallization kinetics between Fe20Co20Ni20Cr20(P0.45B0.2C0.35)(20) high-entropy metallic glass (HEMG) and the predecessor Fe75Cr5P9B4C7 metallic glass (MG) was conducted using X-ray diffraction and differential scanning calorimetry approaches. The results showed that the HEMG has a harsher crystallization process with higher triggering energy and local activation energy, as well as a smaller local Avrami exponent and a growth with pre-existing nuclei. On the other hand, the predecessor MG has distinctly different crystallization features with moderate difficulty and diverse nucleation rate.

Summary: The study demonstrated the preparation of Fe-Zn-SA/NC catalyst for efficient ORR reaction in all pH range, showing high half-wave potentials and stability, comparable to Pt/C. The Fe-Zn-SA/NC catalyst also exhibited high power density and durability when assembled into a Zn-air battery, indicating its potential for real energy-related devices. The theoretical calculations attribute the superior catalytic activity of Fe-Zn-SA/NC to the lower energy barriers of ORR at the Fe-Zn-N-6 centers, offering new insights for dual-atom catalysts in energy conversion related catalytic reactions.

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.

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.
