Summary: Rare-earth orthoferrites (RFeO3) are emerging as a type of microwave absorbing material (MAM) with great potential due to their excellent structural stability and moderate permittivity. In this study, La1-xCaxFeO3 ferrite MAMs were synthesized using a sol-gel technology, showing that an appropriate amount of Ca doping can enhance the microwave absorption of LaFeO3. The ideal microwave absorption was achieved when Ca content x = 0.1 and 0.15, demonstrating the potential of La1-xCaxFeO3 as a high-performance MAM.

Summary: Single-phase La0.7Sr0.3Mn1-xFexO3 perovskites were synthesized by sol-gel method and had a rhombohedral structure with a slight change in lattice parameters and unit cell volume. The average particle size ranged from 43-70 nm. The samples exhibited a ferromagnetic to paramagnetic second-order magnetic phase transition at TC, which decreased linearly with Fe doping. XPS measurement confirmed the oxidation states of Fe and La as +3 and a mixed valence state of Mn4+/Mn3+. The Fe substitution suppressed the saturation magnetization and blocking temperature, while (-4SM)max decreased with increasing Fe content. The sample with x = 0.08 showed a Curie temperature of 297 K, the highest relative cooling power (RCP) of 153 J/kg, and (-4SM)max value of 1.46 J/kg.K at mu o4H = 2.8 T. The La0.7Sr0.3Mn1-xFexO3 manganites are potential candidates for room-temperature magnetic refrigeration applications.

Summary: Wastewater treatment is crucial due to its harmful effects on nature and living creatures. Dyes, especially organic pollutants, pose serious risks to human health and the environment in wastewater. This study focuses on removing these colored effluents from wastewater, both individually and in mixtures. Nano photocatalysts La1-xNaxFeO3 and their Cu composites were synthesized and characterized for their structural, morphological, optical, and magnetic properties. The Cu nano composites exhibited excellent photocatalytic activity, attributed to their low band gap energies. The stability and reusability of the most active photocatalyst, LaFeO3@Cu, were demonstrated. Additionally, the study extended its scope to the degradation of other organic dye contaminants using the same catalyst. (c) 2023 Elsevier B.V. All rights reserved.

Summary: The temperature variation of the lower critical Hc1 field in the noncentrosymmetric superconductor alpha-BiPd was investigated using Hall micromagnetometry. The measurements were performed down to 0.3 K in a magnetic field applied along the crystallographic b axis. Below the critical temperature Tc, which is around 3.8 K, a conventional Hc1(T) dependence, typical for a single-band s-wave superconductor, was observed. The obtained data indicate an absence of spin-triplet component in the superconducting wavefunction and marginal multiband effects in this material, contrary to some literature reports.

Summary: Recent discoveries of materials with ultralow thermal conductivity provide a pathway for significant developments in thermoelectricity. A comparative study of three chemically similar antimonides reveals the root causes behind their extraordinarily low thermal conductivity. The study shows that localized phonon modes with unusually low frequencies and framework bonding contribute to the suppression of thermal conductivity. Understanding thermal transport in structurally complex materials is crucial for the development of the next generation of thermoelectrics.

The crystal structure was found to be tetragonal, and the Y-, La-, and Lu-based phases were diamagnetic, while Yb2Au2Pb exhibited an intermediate valence system. The other R2Au2Pb ternaries showed antiferromagnetic ordering at low temperatures due to localized magnetic moments carried by trivalent R3+ ions.

Summary: Nano- and microscale zinc oxide (ZnO) shows promise as an antibacterial agent in biomedical applications, but the mechanisms behind its antimicrobial action are unclear. This study investigates the effects of interactions with phosphate-rich environments and bacteria on ZnO particles. The results demonstrate significant changes in surface photovoltage and sub-bandgap surface electronic structure after exposure to phosphate-rich environments, suggesting adsorption of phosphates at zinc deficiency defects on the ZnO surface. However, the presence of Staphylococcus aureus bacteria suppresses this effect, supporting the competitive nature of interactions between S. aureus, aqueous phosphates, and the free surface of ZnO.

Summary: The aim of this study was to evaluate the dynamics of fluoride ion release from first- and second-generation fluoride varnishes and the impact of varnish type, time from application, and pH of the environment. The results showed that MI Varnish had the highest fluoride release (11.52 ppm/mg) regardless of the pH, while Embrace Varnish had the lowest fluoride release (4.82 ppm/mg). In an acidic environment, the fluoride release was significantly higher than in a neutral environment, and the maximum release occurred within the first two hours after application.

Summary: We investigated the physical properties of CeGaGe and PrGaGe single crystals using magnetization, heat capacity, and magnetotransport measurements. Magnetic phase transitions were observed at around 6.0 K and 19.4 K in CeGaGe and PrGaGe, respectively. Additional anomalies below the ordering temperature indicate a complex magnetic structure. The analysis of the crystalline electric field (CEF) effect suggests the splitting of the multiplet in CeGaGe and the degenerate ground state in PrGaGe into different energy levels.

Summary: We investigated the pressure effects on the electronic and crystal structures of EuCoGe3, a noncentrosymmetric antiferromagnet. By performing high-pressure fluorescence detected near-edge x-ray absorption spectroscopy and synchrotron powder x-ray diffraction, we found that the valence state of Eu changes under pressure, while the Co and Ge spectra remain unchanged. The lattice parameters of EuCoGe3 decrease with increasing pressure, but the crystal symmetry remains unchanged.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
