Summary: The electronic structure of nanoparticles in binary mixtures of oxides was studied using the example of CeO2-In2O3. The study focused on the effect of catalytically active CeO2 nanoclusters on charge distribution in nanoparticles with a high concentration of conduction electrons (In2O3). It was found that the spillover of oxygen atoms from CeO2 nanoclusters to In2O3 nanoparticles resulted in an enhancement of the inhomogeneous distribution of conduction electrons, leading to a depletion of the near-surface layer. The film resistance increased with an increase in CeO2 concentration, attributed to a decrease in near-surface electron density in In2O3 nanoparticles and overlap of current flow paths by CeO2 nanoclusters.

Summary: A random network of indium-gallium-zinc oxide (IGZO) nanowires was fabricated using electrospun-PVP-nanofiber template transfer. Compared to electrospun IGZO nanofibers, the nanofiber template-transferred IGZO nanowires demonstrated higher transmittance, stronger substrate adhesion, superior electrical performance, and operational reliability and uniformity. The proposed IGZO nanowires fabricated by PVP nanofiber template transfer are expected to overcome the limitations of conventional electrospun IGZO nanofibers.

Summary: This study focuses on the distribution of oxygen vacancies in In2O3 and their impact on structural stability and electronic properties. The formation energies of oxygen-vacancy pairs in a specific supercell depend significantly on the distance between vacancies. The gap states induced by oxygen vacancies move towards the valence band maximum with decreasing vacancy distance, affecting the conductivity.

Summary: The graphene oxide (GO) modified In2O3 composite catalyst plays an important role in CO2 hydrogenation to methanol by promoting the formation of hexagonal In2O3, inhibiting the reduction of In2O3, and facilitating the generation of oxygen vacancies. The formation energy of oxygen vacancies at the interface of h-In2O3(1 1 0) and c-In2O3(4 4 0) homojunction is lower, indicating easier generation of oxygen vacancies. The catalyst with 8% GO content achieves high methanol space-time yield (STY) and selectivity.

Summary: In this study, In2O3/PANI composites were synthesized using the hydrothermal technique to explore their sensing capabilities for NO2 gas. The gas sensing properties, such as response/recovery time, optimal temperature, and recyclability, were investigated by analyzing the morphology, purity, and crystal structures of the samples. The In2O3/PANI-1 sensors exhibited high responses, quick response and recovery times, and a low detection limit to NO2 gas at a working temperature of 250 degrees C. The fundamental detecting mechanism for NO2 gas and the electrical characteristics of the In2O3/PANI composites were also discussed.

Summary: This study investigated the electrical properties of Al/(5% Gr-PVA)/p-Si structures using impedance measurements and found that using a high dielectric organic interface layer such as (5% Gr-PVA) can significantly increase the capacitance in a capacitor. The values of complex dielectric and electric modulus were influenced by frequency, while lower M' values at low frequencies were related to the mobility of charge carriers. Peaks observed in tan delta-V and M''-V plots varied in magnitude and position with changing frequency, suggesting the importance of the (5% Gr-PVA) organic interlayer for its flexibility, low energy consumption, and simple growth process.

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.
