Summary: The properties of materials are heavily influenced by the size of domains/grains, showing a non-monotonic relationship. In bulk Ni2Mn1+xGa1-x alloys, the exchange bias effect is influenced by the size of ferromagnetic clusters and can be regulated by changing the density of the FM/AFM interface.

Summary: The toughness of the coarse-grained-heat-affected-zone (CGHAZ) strongly depends on the prior austenite grain size, which is affected by various factors including chemical composition, thermal cycle, and base metal microstructure. The impact toughness of CGHAZ was found to be higher in the air-cooled base metal compared to the water-quenched base metal due to differences in microstructure.

Summary: The microstructure, magnetic and elastic properties of Ni0.6-xZn0.4MnxFe2O4 (x = 0-0.6) ferrites prepared by sol-gel auto-combustion method were studied. The XPS results showed the presence of Ni2+, Zn2+, Mn2+, Fe3+ in the specimens. The XRD measurements confirmed that all samples annealed at 1100 degrees C had a pure cubic spinel structure. The lattice parameter and grain size increased with increasing Mn2+ substitution. Mn ions gradually preferred to occupy the A-site in the samples as indicated by Rietveld refinement. The FTIR spectra showed a shift toward low wavenumber, indicating elongation of the bond length, which resulted in a decrease in the elastic constants. The saturation magnetization increased monotonously from 75.6 to 81.6 emu/g as x increased from 0 to 0.6. In addition, the initial permeability increased monotonously from 122.5 to 545.6 due to the transition from NiZn ferrites to MnZn ferrites. Compared with the annealing process in previous work, it was found that cooling in vacuum could improve the microstructure and magnetic properties. The mixed NiZnMn can be applied in high frequency.

Summary: This study investigates the structural, electronic, optical, and semiconducting properties of monoclinic KCa2Nb3O10 layered perovskite under pressures up to 400 GPa using density functional theory (DFT). The calculated results are in good agreement with experimental values. The compound exhibits a direct bandgap nature at all pressures and becomes metallic at 400 GPa. Nb-4d and O-2p states at the Fermi level make the most significant contribution to the density of states under pressure. In terms of optical properties, the material is highly reflective and shows maximum absorption in the infrared band at 400 GPa. These findings suggest that pressure significantly affects the properties of KCa2Nb3O10 perovskite and holds promise for optoelectronic applications.

It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
