Summary: The effect of adding reduced graphene oxide (rGO) to plasma-sprayed coatings was studied, and it was found that increasing the proportion of rGO reduces the porosity and enhances the resistance to crack propagation. Adding rGO as an additive is considered a promising solution to improve the characteristics and properties of plasma-sprayed coatings.

Summary: A new method was developed to spray a uniform composite coating of copper nanoparticles and graphene nanoflakes onto a metal substrate using an inductively-coupled radio frequency plasma torch. The resulting coatings exhibited microstructural uniformity, strong coating splats cohesion, and good retention and dispersion of graphene nanoflakes within the copper matrix. Moreover, the copper-graphene composite coatings showed strong antibacterial properties, achieving a 99% reduction of Escherichia coli bacteria within 1 hour.

Summary: This paper focuses on the oxidation behavior of novel double-ceramic-layer thermal barrier coatings (DCL TBCs) deposited by atmospheric plasma spraying (APS) and suspension plasma spraying (SPS). Results showed that the developed APS-SPS DCL TBCs have better oxidation resistance than the single layer SPS TBC. In terms of oxidation rate and lifetime, segmented APS-SPS TBCs perform slightly better than columnar APS-SPS TBCs. Among the various APS-SPS TBCs, segmented dense APS-SPS TBCs with low vertical crack density appear to have more potential for industrial application.

Summary: This paper discusses the influence of 40 wt% TiO2 addition to Al2O3 and the selection of plasma spray parameters on the morphology, microstructure, microhardness and adhesion of coatings. The tribological behavior and cavitation erosion performance of the coatings were evaluated. The study found that increasing the torch scan speed and decreasing the spraying distance improved the densification and mechanical properties of the coatings, leading to enhanced cavitation erosion resistance.

Summary: This study investigated the influence of suspension characteristics on the performance of suspension plasma sprayed thermal barrier coatings (TBCs), revealing that TBCs produced using different suspensions showed varied performance. TBCs produced using ethanol suspension exhibited the best TS lifetime, while TBCs produced using water suspension with solid load content showed the lowest lifetime. Additionally, TBCs produced using ethanol suspension showed slightly better thermal cyclic fatigue lifetime compared to TBCs produced using water and ethanol-water mixed suspensions.

Summary: Yttrium-stabilized zirconia (YSZ) thermal barrier coatings (TBCs) are essential in turbine propulsion systems. The application of YSZ coatings deposited with atmospheric plasma spraying (APS) is limited due to their inability to withstand frequent thermomechanical loading. However, modifying the plasma spraying process by using nano-structured suspension instead of micrometric powders offers the highest improvement in properties and requires minimal changes in industry procedures.

Summary: Suspension plasma spraying (SPS) technique was used to produce CuO coatings with different properties. The tribological performance of the coatings was studied under different temperature and sliding conditions. The results showed that the friction coefficient and wear rate of the CuO coatings varied with temperature, and different wear mechanisms were observed. The formation of a smooth uniform tribofilm at higher temperature contributed to the improved tribological behavior.

Summary: Lead-free piezoelectric powders were synthesized using both conventional and microwave-assisted methods. The study evaluated the physical properties and sintering characteristics of the materials. X-ray diffraction analysis revealed the formation of perovskite structure with orthorhombic geometry, but the presence of secondary phases was also observed. Microwave sintering resulted in microstructures with porosity, liquid phase, and secondary phases, leading to a decrease in the piezoelectric constant.

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: 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: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

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.
