Summary: In this study, BaTi1-mZrmO3-4.5 mol.% Gd2O3-2.0 mol.% SiO2 ceramics with different Zr/Ti ratios and MgO contents were prepared. MgO addition decreased the densification temperatures of the ceramics and increased the second phase Ba2GdZrO5.5 content. The temperature coefficient of capacitance curves had an almost linear variation with temperature, with negative temperature coefficients, while the MgO addition and Zr4+/Ti4+ ratio increase led to a counter-clockwise rotation of the temperature coefficient of capacitance.

Summary: In this study, the electrical performance of BaBiNb5O15 (BBN)-based oxide-ion conductors was improved through Sr2+ ion doping and sintering process improvement. The bulk conductivity of BaBi1-xSrxNb5O15-delta compounds first increased and then gradually decreased with increasing Sr2+ doping amount, and the best bulk conductivity was obtained at a doping concentration of 2 mol%. Compared with the traditional sintering method, the total conductivity of the sample prepared by the two-step sintering method was greatly improved.

Summary: Oxygen transport membranes (OTMs) are a promising technology for oxygen production, offering lower costs and power consumption compared to cryogenic air separation or pressure swing adsorption. Dual-phase OTMs, composed of a stable ionic conductor and electronic conductor composite, have advantages over single-phase membranes in terms of chemical and mechanical stability. However, challenges remain in their large-scale employment.

Summary: This study investigated the Lu doping of Ba0.5La0.5CoO3 and its effect on the exsolution of oxide nanoparticles. The Lu doping caused phase segregation into the main BLCO-Lu phase and the secondary BCO-Lu phase. Exsolution of BCO-Lu nanoparticles on the main BLCO-Lu phase and vice versa was observed, indicating mutual exsolution of oxide NPs. Trace amount of the BaLuCo4O7 phase was also detected. The size and shape of the exsolved oxide NPs could be controlled by varying the annealing temperature. The findings provide potential for designing novel, more catalytically active materials for future electrochemical devices.

Summary: This study investigates the formation energetics and stability of BaLnCo(2)O(6-delta) (Ln = La, Pr, Nd, and Gd) (BLnC) and BaGd1-xLaxCo2O6-delta, where x = 0.2, 0.5, and 0.7 (BGLC) double perovskite cobaltites under high water partial pressure. These materials have potential applications in electrochemical devices as positrodes. It is found that all investigated materials are thermodynamically stable relative to binary oxides and exhibit exothermic enthalpies of formation. The BGLC compounds show higher negative formation enthalpies compared to single-Ln compositions, but the BLnC series demonstrate better chemical stability under high steam pressures.

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.
