Summary: CdS/rGO nanocomposites were prepared via a facile one-pot hydrothermal method with different mass ratios of rGO. The nanocomposites exhibited hexagonal structure with one-dimensional CdS nanorods decorated on the surface of graphene, showing excellent visible light absorption and enhanced photocatalytic activity in degradation of MO under simulated sunlight irradiation. The nanostructure accelerated the separation and migration efficiency of photogenerated electron-hole pairs, inhibited recombination of photogenerated carriers, and enhanced electron transportation in photocatalytic reactions. In addition, ·O-2(-) and ·OH played a key role in the photocatalytic degradation process.

Summary: Pure ZnO, Ag-doped ZnO, Ce-doped ZnO, and Ag-Ce/ZnO nano-photocatalysts were synthesized using the hydrothermal method. The Ag-Ce/ZnO photocatalysts showed excellent photocatalytic performance compared to pure ZnO, Ag-doped ZnO, and Ce-doped ZnO due to their superior optical and photoelectrochemical properties. Photodegradation experiments demonstrated that the Ag-Ce/ZnO photocatalysts could degrade 97% of RhB dye within 30 min. Superoxide radicals were found to play an active role in the photodegradation reaction, and a possible degradation mechanism of Ag-Ce/ZnO was proposed.

Summary: In this study, a CuS@ZnO/CdS catalyst was synthesized using low-temperature hydrothermal and water bath methods. The coupling of CdS and CuS onto ZnO surfaces was confirmed using various characterization techniques. The CuS@ZnO/CdS catalyst exhibited a significantly higher Rhodamine B degradation rate constant compared to ZnO, attributed to the decreased bandgap and enhanced ability to absorb visible light. The study also proposed a dual Z-scheme carriers movement mechanism and analyzed the mineralization rate of RhB after degradation, demonstrating the practical application potential of metal chalcogenide-modified ZnO-based photocatalysts in environmental purification.

Summary: In this study, two-phase WO3 photoelectrodes with different morphologies were obtained by controlling the concentration of Na2WO4 in the precursor solution, and their performance in photoinduced cathodic protection (CP) was explored. The heterojunctions formed between hexagonal and monoclinic WO3 contribute to the directional separation of photogenerated carriers. Additionally, the ordered growth of WO3 nanorods perpendicular to Ti substrate facilitates the directional transmission of photogenerated carriers, resulting in good photoinduced CP performance.

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.
