Summary: The high thermal energy has a destructive effect on thermoplastic-based laminates, causing the matrix to deteriorate and form voids. Despite being weak from a mechanical perspective, these voids act as thermal insulators and protect the matrix from thermal aggression. Accurate description of the kinetics of void formation is crucial in controlling the thermomechanical properties evolution of laminates under fire conditions.

Summary: Photocatalytic technology is a promising alternative for water treatments, but its practical application is limited by low efficiency and selectivity. In this study, two-dimensional zinc oxide nanosheets decorated with copper-palladium bimetallic nanoparticles were synthesized for the degradation of organic dyes in water. The prepared composites showed superior photocatalytic performance compared to pristine ZnO nanosheets under visible-light irradiation, attributed to enhanced separation and transfer efficiency of charge carriers. The highest catalytic efficiency was achieved by CuPd/ZnO nanocomposite with 0.5 wt% CuPd, achieving 95.3% removal of methyl orange within 45 minutes. This study provides a new avenue for the design and fabrication of high-performance photocatalysts for water treatments.

Summary: To increase the capacitance of an inorganic electrode material, CoFe-layered double hydroxide (LDH) was grafted onto the surface of hexagonal-flower-like NiCo2O4. Various composites with different Co/Fe ratios were grown directly on Ni foam using the hydrothermal method. The composite with a Co/Fe molar ratio of 1:2 (NiCo2O4 @Co1Fe2-LDH) exhibited the best electrochemical performance, with a specific capacitance of 2595 F g-1 at a current density of 1 A g-1. The composite prevented aggregation of CoFe-LDH, leading to high specific capacitance and good stability. The electrode was used in a packaging asymmetric capacitor, resulting in a maximum energy density of 27.33 Wh kg-1 at a power density of 800 W kg-1 and an excellent capacitive retention of 96% even after 5000 charge-discharge cycles.

Summary: The effects of Lc on the depth of the operative interphase, operative filler concentration, and mechanical percolation start are studied. An equation is proposed to determine the strength of HNT composites with an imperfect interphase and an HNT network. The relationships between B and Lc, HNT size, and percolation start are analyzed. The lowest Lc, lowest percolation start point, slimmest and longest HNTs, and highest interfacial shear strength yielded the highest B values and the toughest samples.

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.
