Summary: Reversible solid oxide cells (RSOCs) often suffer from thermal property mismatching between electrodes and electrolyte, leading to reduced energy efficiency and irreversible performance degradation. Symmetrical RSOCs (SRSOCs) using identical electrode materials offer a solution to address these issues and simplify the manufacturing process. La1-xSrxFeO3-$ perovskites are developed and applied as both fuel and air electrode materials for SRSOCs, showing improved crystal structures, conductivities, and electrochemical performance after Sr substitution for La. The La0.9Sr0.1FeO3-$ symmetrical cell exhibits stable operation for 128 h under SOFC mode and 25 h under SOFC-SOEC cycle mode, making it a promising multifunctional electrode material for SRSOCs.

Summary: In order to create efficient solid oxide fuel cells, suitable functional materials are needed to satisfy the requirements for both fuel and oxygen electrodes. By investigating the properties of La1-xBaxFeO3-delta materials, it was found that La0.6Ba0.4FeO3-delta exhibits the highest electrical conductivity and acceptable thermal expansion behavior, making it suitable as an oxygen electrode. However, the transport properties under reducing atmospheres need improvement for the successful use of La1-xBaxFeO3-delta as symmetrical electrodes.

Summary: The study investigated 96 samples in the Ba1-xPrxFe1-yCoyO3-delta system, establishing the compositional boundaries of stability for three types of crystal structure. The cubic and orthorhombic perovskites' unit cell parameters were refined, and the oxygen content was found to increase with Pr and Fe contents. A pseudo-phase diagram outlining the stability ranges for all three types of complex oxides was generated.

Summary: Counter-flow microfluidic fuel cell faces problems of non-uniform reaction rate distribution and poor electrode contribution. This study introduces a novel trapezoidal electrode design to improve its performance. Numerical analyses show that the isosceles trapezoidal electrode performs better than rectangular electrodes even at lower flow rates. The improved performance is attributed to the enlarged active region, reduced ionic resistance, and distinctive fluid distribution. Further optimization studies suggest that the isosceles trapezoidal design is preferred. Overall, the trapezoidal electrode shows promise for counter-flow microfluidic fuel cells and warrants further development.

Summary: This study focuses on the analysis of SDC nanopowders and NiO/SDC nanocomposites in terms of their reducibility and catalytic activity for partial oxidation of methane. The results show that the crystallite size and surface area play a crucial role in methane activation by modifying the sample's redox behavior, with the oxidation of the metallic phase being the main cause of sample deactivation. A complex relationship between oxygen vacancy concentration and catalytic activity was observed during the experiments.

Summary: Optimization of the MgB2 superconducting material's intrinsic and extrinsic properties is crucial for its practical applications in cables, wires, and tapes. Various mechanisms such as synthesis process, grain connectivity improvement, densification, pinning, doping, and MgO formation limitation are used to achieve this optimization. Addition of elements like Ti, Zr, Hf, Al, Mn, Si, etc., as dopants, can enhance the flux pinning behavior and transport properties. In this study, MgB2 superconducting bulks with AlB2 powder additions were prepared and analyzed, leading to an increase in critical current density and irreversibility field compared to pure MgB2.
