Summary: This work studied the properties of nanostructured (1 - x)ZrO2 - xCeO2 composite ceramics and established the relationship between the phase composition and strength properties. The variation of oxide components led to phase transformations, strengthening the ceramics and increasing crack resistance. The change in phase composition and displacement of ZrO2 phase significantly enhanced the ceramics by more than 3.5-4 times and improved resistance to cracking by more than 2.5 times.

Summary: High-entropy ceramics (HEC) with a fixed composition of (VNbTaMoW)C5 were prepared by spark plasma sintering (SPS) at temperatures ranging from 1500 degrees C to 2200 degrees C. The study showed that higher sintering temperatures led to improved compositional homogeneity and microstructure of the HECs, with single-phase HEC formed at 1600 degrees C and ultimate distribution homogeneity achieved at 2200 degrees C. Additionally, sintering at 1900 degrees C for 12 minutes yielded uniform HECs with excellent mechanical properties.

This study focuses on using Moringaoleifera pods and kernels powder for removing methylene blue dye from water. The adsorption process follows the pseudo-second-order model, and the adsorbents were characterized using FT-IR, XRD, and SEM. The optimization process determined the optimal conditions for MOPP and MOKP, achieving high removal efficiencies of 98.12% and 96.94% respectively. The chosen model was validated by experimental data, and ANOVA confirmed the high-efficiency adsorbent capacity of the materials.

Summary: In this study, the bonding length, electronic structure, stability, and dehydrogenation properties of the Perovskite-type ZrNiH3 hydride under different uniaxial/biaxial strains were investigated through ab-initio calculations. The results show that compressive and tensile strains cause structural deformation of the ZrNiH3 crystal structure, and the magnitude of deformation becomes more significant with decreasing or increasing strain. The strain not only reduces the stability of ZrNiH3 but also decreases the dehydrogenation enthalpy and decomposition temperature. The densities of states analysis suggests that the strain-induced variation in the properties of ZrNiH3 is related to the Fermi level value of total densities of states.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
