Summary: Electrodeposition was used to prepare nickel graphene oxide (Ni-GO), nickel silicon carbide (Ni-SiC), and nickel graphene oxide/silicon carbide (Ni-GO/SiC) composite coatings on a 2218 aluminum alloy substrate. The composite coatings exhibited dense and defect-free microstructures, strong bonding with the substrate, and significantly increased microhardness. The friction coefficient and wear rate of the composite coatings were lower compared to the substrate. Among the composite coatings, the Ni-GO/SiC composite coating showed the best overall tribological performance.

Summary: This study investigates the influence of preloads on the tribological performance of molybdenum disulfide/graphene composite lubricating coating. It is found that the preload has a positive effect on the friction coefficient of the coating, with a decrease in friction coefficient as the preload increases, further improving the tribological performance. This research provides guidance for the selection strategy of preload for optimal tribological performance of solid lubricating coatings.

Summary: Metal matrix composites reinforced with WC particles and Co or Ni matrices are known for their unique combination of hardness, toughness, and superior wear performance. This study focused on Ni-WCNi composite coatings and found that coatings with higher WC fill ratios displayed better wear resistance due to the uniform distribution of WC particles and shorter mean free path reducing adhesive wear. However, at higher loads, subsurface crack propagation at WC particle interfaces led to a reduction in the protective role of mechanically mixed layers. Scratch tests were used to qualitatively compare coating cohesion strengths and correlate them to wear properties.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
