Summary: The study explores the correlation between the ratio of hardness to elastic modulus (H/E) of coating systems and their wear resistance. It discusses experimental approaches to determine accurate H/E values and summarises best practice recommendations. Case studies demonstrate the importance of relatively low coating elastic modulus in reducing tensile stresses.

Summary: The study demonstrates that different morphologies of Nb2O5 supports significantly influence the catalytic activity of MnOx catalysts, with the layer-like morphology of MnOx/Nb2O5-L showing the best performance. However, MnOx/Nb2O5-L exhibits good surface dispersion and strong metal-support interaction, but suffers from irreversible deactivation after long-term catalytic reactions.

Summary: This study reported a facile method to synthesize mangosteen peels activated carbon (MSPAC) with high carbon content and mesoporous structure. MSPAC showed excellent adsorption capability for methylene blue (MB) dye removal from aqueous solutions. The optimization of adsorption conditions using response surface methodology resulted in the best parameters for maximum MB removal. The kinetic and equilibrium results were best represented by the PSO and Langmuir models, respectively. Thermodynamic findings indicated that the adsorption process was spontaneous and endothermic. This work highlights the significance of MSPAC as an environmentally friendly adsorbent for removing cationic synthetic dyes from polluted water.

Summary: The peak position of C 1s can be affected by the vacuum level alignment and differential charging. However, recent studies suggest that differential charging may not be the general cause of C 1s peak shifts. Experimental results confirm that the binding energy of C 1s peaks in metal foils is determined by their work function values.

Summary: Transition metal sulfides, particularly 1T-MoS2, have been explored as promising anode materials for rechargeable batteries due to their high electrical conductivity, thermal stability, and excellent electrochemical performance. Density functional theory calculations reveal strong binding between metal ions and 1T-MoS2, along with good ion diffusion rates and appropriate open-circuit voltages and specific capacities. Thus, 1T-MoS2 demonstrates great potential as an anode material for lithium-ion, sodium-ion, and magnesium-ion batteries.

Summary: In this study, a novel bimetallic zeolitic imidazolate frameworks (ZIFs) have been fabricated for the elimination of toxic dye from water. The synthesized ZIF-8@ZIF-67 showed improved physical and chemical properties compared to single metallic MOFs (ZIF-67 and ZIF-8). Langmuir model was found to sufficiently explain the adsorption process of ZIF-8@ZIF-67, and the mean free energy suggested chemisorption dominates the adsorption. The high applicability and reusability of the bimetallic MOFs were demonstrated through the removal of rhodamine B from water.

Summary: By using a mechano-chemical strategy with Na assisted milling, a multi-defective spinel catalyst D-NiCo2O4 was developed, which exhibited significantly elevated oxygen vacancies, raised active oxygen species, enhanced oxygen mobility, and increased specific surface area. This catalyst showed superb activity for propane catalytic oxidation, outperforming pristine NiCo2O4 and Co3O4 catalyst, making it one of the most outstanding non-noble metal catalysts for propane oxidation. This work set a paradigm for enhancing the VOCs oxidation performance of metal oxide catalyst by multi-defects engineering.

Summary: Carbon fiber reinforced polymer (CFRP) is widely used in the lightweight design of high-speed trains. In this study, CFRP plate and 5083P-O aluminum plate were successfully joined using induction brazing. Anodization of the aluminum plate increased the wetting behavior and bonding strength between CFRP and oxide film. High-cycle fatigue testing revealed a low fatigue limit for the CFRP/5083 joint.

Summary: In this study, a high-efficiency 3D/2D g-C3N4/Ti3C2 heterojunction photocatalyst was designed for photocatalytic hydrogen evolution and organic dye elimination. The excellent performance of the material is attributed to its 3D interconnected porous structure and the incorporation of Ti3C2 nanosheets, providing a high specific surface area and efficient charge migration. Mechanisms for the improved photocatalytic performance were analyzed through characterization measurements, active species analysis, and density functional theory calculations.
