Summary: Zinc telluride is a versatile wide band gap semiconductor used in many applications, but it has limitations in terms of size and band gap. Introducing alkali metal and lanthanide to its lattice can reduce dimensions and cause a red shift in the energy gap. CsLnZnTe3 compounds, formed by incorporating alkali and lanthanide into zinc tellurides, exhibit layered crystal structure with direct band gaps. The band gaps of these compounds have not been evaluated yet, and calculations were also performed for energy loss functions, refractive index, and dielectric functions to explore their potential applications in optoelectronic devices.

Summary: Four different ZnO nanostructures, including nanoparticles, nanorods, nanoribbons, and nanoshuttles, were synthesized by controlling pH levels, chemical compositions, and process conditions. The properties of these nanostructures, such as structure, wettability, optics, and electrical conductivity, depend on their morphology and particle size. ZnO nanoparticles are hydrophilic, while other nanostructures are hydrophobic. Moreover, ZnO nanorods exhibit higher electrical conductivity compared to other nanostructures, whereas ZnO nanoshuttles have the lowest electrical conductivity. Grain boundaries and semiconducting nature play a role in influencing the electrical conductivity of ZnO nanostructures.

Summary: This study explores a promising alternative for manufacturing anodes for sodium-ion batteries and evaluates the properties of nanostructures of sodium titanate by examining the pH variation during hydrothermal synthesis. The experimental results show that the relative weight between phases and the direct band gap can be controlled by adjusting the pH conditions, leading to changes in the morphology of the structural phases. Additionally, the changes in electrical properties over a possible operation temperature range of a potential device are discussed.

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.
