Summary: Homogeneous substitution of Dy for Nd in the 2:14:1 phase can enhance coercivity but reduce remanence. A comparative study showed that multi-main-phase magnet with inhomogeneous Dy distribution has better magnetic properties and thermal stability than single-main-phase magnet with homogeneous Dy distribution. The multi-main-phase magnet exhibited higher coercivity, remanence, and energy product at room temperature and over a wide temperature range.

Summary: The grain boundary diffusion process (GBDP) significantly improves the magnetic properties and thermal stability of sintered Nd-Fe-B magnets, enhancing coercivity and decreasing remanence. Diffusing Dy70Al10Ga20 and (Pr75Dy25)(70)Al10Ga20 alloys leads to an increase in coercivity and an improvement in thermal stability of the magnets. The microstructure modifications, such as Rare-earth-rich grain boundary phases and core-shell structures, play a crucial role in enhancing coercivity.

Summary: The introduction of Holmium into Nd-Fe-B permanent magnetic materials can significantly enhance coercivity and improve the thermal stability of the magnets. High levels of Ho substitution can lead to an increase in remanent magnetization at elevated temperatures, attributed to the antiparallel coupling between Ho and Fe moments. Additionally, the coercivity temperature coefficient beta is also improved with Ho substitution, indicating the beneficial effects of Ho on thermal stability in Nd-Fe-B magnets.

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.

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.

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.
