Summary: In this study, Co-substituted Ni-Zn ferrites were synthesized, and their structural and magnetic properties were investigated. The results showed that Co substitution led to an increase in crystallite size and lattice constant, as well as a suppression of Raman peak intensity and shift towards a lower wavenumber. The dielectric properties and magnetic response of the samples were also affected by Co substitution. At low temperatures, the Co-substituted ferrites exhibited a giant coercivity and high effective magnetocrystalline anisotropy.

Summary: In this study, commercial Fe2O3-rich ferrite powders were densified by cold sintering at 300 degrees C with the assistance of organic salts, resulting in improved initial permeability and a Curie temperature of 125 degrees C. The dehydration of organic salts provided a medium liquid phase that triggered the densification process of the ceramics. The excessive Fe2O3 entered into the spinel structure forming a solid solution through annealing in low pO(2).

Summary: The use of mixing rules in predicting the properties of composite materials and coatings is highly valuable. This study focuses on the application of mixing rules to permittivity and permeability and the retrieval of intrinsic properties of inclusions. The experimental results show that there are differences between the mixing rules for permittivity and permeability in composites, which can be attributed to the non-ideal electrical contacts between neighboring inclusions.

Summary: The study focused on preparing Ni0.4Co0.25Zn0.35Fe2O4 ferrites with the addition of CuO dopants to enhance their magnetic properties, achieving high permeability and low magnetic loss for potential applications in RF and microwave devices. High relative permeability and low magnetic loss were achieved in the frequency range of 100-800 MHz, with the addition of CuO causing a significant increase in permeability. Moreover, the resonance frequency of the ferrites shifted to the GHz range with higher concentrations of CuO dopants.

Summary: The effect of Co content on the magnetic properties of Ni-Zn ferrites is mainly reflected in the decrease of Curie temperature and the increase of Ms, Mr, and Hc. These changes are primarily due to the larger magnetic moment of the Co2+ ion, as well as the influence of the difference in ionic radii. The non-linear concentration dependence of magnetic characteristics is discussed in terms of Co2+ spin states.

Summary: The dominant magnetic interaction in La2CuO4 is superexchange between nearest-neighbor Cu moments, but the pinning of the spin direction depends on weak anisotropic effects associated with spin-orbit coupling. The symmetry of the octahedral tilt pattern allows for out-of-plane canting of the Cu spins, which can be compensated by opposite canting in nearest-neighbor layers. Applying a strong magnetic field perpendicular to the planes can induce a weak ferromagnetic phase by altering the spin canting pattern.

Summary: This study investigated the sintering behavior, microstructure, and permeability of Ni0.50Zn0.50Fe2O4 ferrite sintered at temperatures ranging from 1000 degrees C to 1400 degrees C with different dwell times. The results showed that the maximum shrinkage rate occurred at 1140 degrees C, resulting in samples sintered at temperatures greater than or equal to 1100 degrees C having densities higher than 97%. Moderate grain growth was observed up to 1250 degrees C, but enhanced grain growth occurred if the density exceeded a threshold of 98%. All samples exhibited a single-phase spinel structure with a slightly increased lattice constant with sintering temperature. At temperatures greater than or equal to 1300 degrees C, significant ZnO evaporation occurred, leading to changes in ferrite composition indicated by mass loss, EDX-analysis, and Seebeck coefficient measurements. The complex permeability spectra showed systematic changes with sintering temperature and dwell time. For samples sintered at 1100 degrees C, the permeability increased from mu' = 133 after 30 minutes of dwell time to mu' = 318 after 24 hours of sintering. The variation in permeability was discussed in relation to density and grain size, with the non-magnetic grain boundary model used to interpret the grain-size dependence of permeability.

Summary: This study investigates the phase stability, elastic modulus, and hardness of ternary nitride Ti1-xAlxN. It is found that the hardness increases with the Al content x. The cubic B1 structure is more stable for x < about 0.75, while the hexagonal structure (B4) is more stable for x > about 0.75. The composition dependent hardness and phase decomposition contribute to the convex shaped hardness curve of Ti1-xAlxN.

Summary: This report uses rigorous calculations based on density functional theory to study the piezoelectric and elastic properties of wurtzite aluminum nitride (w-AlN) with single- and co-alloying by Hf (or Zr) and Sc. The research finds that the (HfSc)0.375Al0.625N and (ZrSc)0.375Al0.625N with stable wurtzite phase have a large piezoelectric coefficient d33 of 49.18 pC/N and 47.00 pC/N, respectively. However, the piezoelectric voltage constant g33 and electromechanical coupling constant k233 of HfAlN, ZrAlN, HfScAlN, and ZrScAlN are smaller than that of ScAlN, which is attributed to the large dielectric constant epsilon 33 of Hf (or Zr) alloying samples. Furthermore, the calculations of internal parameter u and bond angle alpha elucidate the brittle-to-ductile transformation in alloying w-AlN crystal structure. Electronic structure calculations show that the bandgap decreases almost linearly with the increase of alloying concentration, and the Hf (or Zr) alloying compounds become n-type semiconductors due to the existing high-charge states.

Summary: This work presents a multilayer film structure that uses optical resonance to prepare highly efficient and saturated red, green, and blue transmittance colors. Numerical simulations and analysis show that the structure can produce R, G, and B colors with a purity comparable to standard RGB colors, while maintaining efficient transmission efficiency and obtaining a rich variety of structural colors. Additionally, a metallic interlayer is introduced to selectively suppress resonances in the short-wavelength region, improving the purity of the red color. The study also investigates the effect of the incidence angle on color purity and transmission efficiency.

Summary: Solubility property is of great interest in chemical, physical, pharmaceutical, material, and environmental sciences. Understanding the intrinsic reason behind solubility behavior is a fascinating task. The theoretical relation between binary mutual solubility and liquid-liquid interfacial tension has been derived, where the partitioning of solute molecules between two coexisting liquid phases is determined by the transfer free energy per unit segment for a chain-like solute molecule expressed in terms of solute-solvent interfacial tension. This general theory of solubility is in good agreement with experimental results for binary mutual solubility and molar transfer free energy of solute molecules.

Summary: The influence of ZrOn matrix stoichiometry on the electrical and magnetoresistive properties of Fe-Zr-O nanocomposites has been studied. It was found that the magnetoresistive effect is not observed in composites with oxygen lack, while composites with oxygen excess show magnetoresistive effect and increased resistivity. Magnetoresistivity in composites with oxygen lack only appears after heat treatment. These results can be explained by the difference in the density of localized states in the oxide matrix of the composites and the ratio between two types of conductivity.
