Summary: The multifunctional properties of ion-doped YFeO3 nanoparticles in hexagonal and orthorhombic structures were investigated theoretically. It was found that the magnetization of h-YFO nanoparticles increases with decreasing size, while for o-YFO nanoparticles it decreases. Both types of YFO nanoparticles exhibit a peak in the dielectric constant around T-C1 at approximately 450 K, with an additional anomaly appearing only in h-YFO at T-C2 around 300 K, potentially related to a phase transition. The polarization in doped o-YFO nanoparticles increases with a magnetic field, and doping with Ti4+ ions results in a shift in the magnetization curve. The transformation between the hexagonal and orthorhombic phases can be achieved by doping ions on Y or Fe sites in YFO.

Summary: By doping Pr up to 15 at%, the high-temperature cubic phase of HfO2 has been stabilized at room temperature, with a coexistence of monoclinic and cubic phases observed between 7 and 13 at% of Pr. The decrease in particle size from 35 to 10 nm, along with the decrease in bandgap from 5.42 to 5.06 eV, is attributed to nonstoichiometric HfO2_x and the formation of sub-bands near the conduction band induced by enhanced oxygen vacancies.

Summary: In this study, Nd-doped zirconia ceramics were successfully prepared using the hydrothermal assisted sol-gel method. With the increase in Nd content, the phase structure of ZrO2 changed and the grain size and compactness of the obtained ceramics increased with the increment in sintering temperature. The successful accommodation of Nd within the ZrO2 lattice was confirmed by the detected increase of cell parameters. This study provides a new method for the immobilization of high-level radioactive waste.

Summary: This paper presents investigations on the effect of Dysprosium (Dy) on the structural and electrical properties of polycrystalline Yttrium Iron Oxide (YFeO3). Samples with different Dy concentrations were prepared through the sol-gel process. The results show that the lattice parameter values increase with an increase in Dy concentration, indicating changes in the crystal structure. The morphology of the samples observed through SEM reveals irregular and non-homogeneous grain sizes. The electrical properties analysis suggests an increase in leakage current density up to a certain concentration of Dy, followed by a decrease.

Summary: This study aims to investigate the correlation between the structural properties of different TiO2 catalysts and their photocatalytic performance and selectivity in CO2 reduction at different pH levels. Two types of TiO2 catalysts were prepared and extensively characterized using various techniques. The prepared catalysts exhibited higher selectivity in CO2 reduction compared to a commercial P25 catalyst. The TiSG catalyst, which had the lowest portion of hydroxyl oxygen species, showed the highest photoreduction efficiency. The study also explored the effect of pH on the efficiency and selectivity of photocatalytic CO2 reduction, revealing different product distributions in acidic and basic environments.

Summary: MnMX alloys, with potential applications as room-temperature solid refrigerants, undergo structural transformation between Ni2In-type hexagonal and TiNiSi-type orthorhombic phases. The crystallography of this martensitic transformation has been unknown due to the difficulty of obtaining a bulk sample with coexisting phases. In this study, the transformation temperature was carefully controlled to obtain a bulk sample with small amounts of orthorhombic phases distributed in a hexagonal matrix. Electron microscopy was used to investigate the microstructure, revealing the crystallography of the hexagonal-orthorhombic transformation for the first time.

Summary: Mixed-phase composites with an optimal phase ratio exhibit improved light utilization compared to monophasic materials. This study focuses on optimizing the phase ratio of hexagonal WO3 (h-WO3·0.33H2O) and orthorhombic WO3·H2O (o-WO3·H2O) to enhance the photochromism of tungsten oxide. The formation of a phase junction between h-WO3·0.33H2O and o-WO3·H2O leads to superior photochromic properties and efficient charge carrier separation and transfer.

Summary: In this study, the hexavalent chromium waste solution after photocatalysis treatment was used for surface passivation of low carbon steel to improve its corrosion resistance. The structure and anticorrosion properties of the passivated steel were analyzed, and it was found that the polarization resistance of the p-HCC film was larger compared to the film treated with pure Cr(III) solution, which may be attributed to the higher Cr content and better interaction between Fe ions and Cr-compound in the p-HCC film.

Summary: In this paper, a flexible asymmetry suppression device (FASD) is proposed to limit the neutral point displacement overvoltage, using a cascaded H-bridge (CHB) inverter and the backstepping control (BSC) method. The FASD compensates for the unbalanced distribution networks caused by the asymmetry of three-phase-to-ground parameters by outputting current to the grid, achieving the suppression of the neutral point displacement overvoltage.

Summary: In order to enhance the mechanical and anticorrosion ability of carbon nanotubes (CNT), CNT were dispersed into homemade silicone-polyurethane (SPU) resin, but before mixing with SPU, CNT were modified using four different approaches. The modified CNT with SiO2-TiO2 nanoparticles exhibited the best mechanical properties and chemical resistance, with a significantly lower corrosion current density compared to unmodified CNT. This may be attributed to the increased roughness of the CNT surface caused by the covered SiO2-TiO2 nanoparticles, which improves their dispersion in SPU resin.

Summary: By using a metal-organic framework (MOF)-based host-guest system, the buried interface of SnO2/perovskite in perovskite solar cells (PSCs) is effectively passivated, leading to reduced energy loss and improved photovoltaic performance. The simultaneous passivation of the buried interface and bulk phase of the perovskite is achieved through the reduction of oxygen vacancies on SnO2 and the binding of uncoordinated Pb2+ and halogen ions at the bottom of the perovskite layer. This modification enhances the photovoltaic efficiency to 22.10% and improves moisture stability and UV resistance capability.
