Summary: One of the most important challenges in materials science is to overcome the trade-off between strength and ductility. Designing alloys with strong precipitates is becoming increasingly popular to address this issue. The brittle sigma phase, which is commonly found in high-entropy alloys, negatively impacts the mechanical properties. In this research, a novel Fe-free high-entropy alloy based on Co-Cr-Ni-Mn-Al is introduced, which has no potential for sigma formation, in order to develop an alloy with a good combination of strength and ductility.

Summary: In this study, the synthesis of CrxN coatings by high power impulse magnetron sputtering (HiPIMS) was investigated, with an evaluation of the effects of different processing conditions on the chemical composition, microstructure, and adhesion of the coatings. Altering the duty cycle was found to significantly impact the deposition rate, chromium and nitrogen content in the coatings, and subsequently affect the crystallographic phases and surface morphology. Reducing the duty cycle was shown to enhance the interfacial adhesion strength of the coatings.

Summary: In this study, Sb2O5-doped AgNbO3 ceramics were prepared and their phase structure, microstructure, dielectric, and ferroelectric properties were investigated. The introduction of Sb5+ ions caused lattice shrinkage and grain size change. The dielectric constant significantly increased with Sb5+ introduction, and the phase transition temperatures shifted to lower temperatures. The AgNb0.98Sb0.02O3 ceramics exhibited relaxor antiferroelectric characteristics, resulting in higher recoverable energy density and energy efficiency compared to pure AgNbO3.

Summary: Oxygen reduction reaction (ORR) is a crucial process for energy storage devices, with the electrochemical activity on carbon surface being determined by its microstructure and composition. In aprotic media, oxygen functionalities do not significantly affect the rate of one-electron oxygen reduction, but in electrolytes containing lithium ions, they enhance the second electron transfer rate and carbon degradation.

Summary: The effects of hydrogen atoms and UV radiation on nanoporous organosilicate glass low-k films were studied. It was found that exposure to hydrogen atoms at low temperature caused slight modification of hydrocarbon bonds in hydrocarbon residues, while high temperature led to the destruction of Si-O and Si-CH2 groups. Additionally, the temperature increase also resulted in slight modification of the matrix structure. UV radiation had almost no effect on these processes.

Summary: This study compares carbon-based cathodes in different aprotic solvents for magnesium-oxygen cells. It was found that the main discharge product in DMSO-based electrolyte is amorphous MgO2, with noticeable concentration of sulfur-containing byproducts. Superoxide was observed during oxygen reduction and MgO2 was predominantly formed by chemical disproportionation of superoxide. Recharge showed that electrode depassivation occurred simultaneously with electrolyte or carbon electrode oxidation. The addition of chloride ions increased discharge voltage without affecting the charge process. These results are important for the further development of electrolyte composition for rechargeable MgO2 electrochemical systems.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
