Summary: In this study, the effect of Zn substitution on the B-site of LNF cathode materials was investigated, resulting in enhanced electrical and electrochemical properties. The experimental results show that LNFZ(3) exhibits 25.4% lower polarization resistance and 52.3% higher maximum power density at 700 degrees C compared to LNF. Additionally, LNFZ(3) demonstrates robust operation under accelerated chromium-poisoning conditions.

Summary: The study demonstrates improved corrosion protection efficiency of a defect-free sol-gel hybrid coating containing cerium oxide nanofibers compared to a sol-gel coating with commercial ceria particles. The organically modified silica-alumina (Si-Al) hybrid sol-gel coating exhibits excellent corrosion resistance and compatibility with the conventional chromate conversion coating (CCC).

Summary: In this study, symmetric electrolyte-supported YSZ cells infiltrated with LSF were prepared, characterized, and tested in the oxygen reduction reaction. The effects of calcination temperature and precursors load on the ORR activity were investigated, with optimal performance achieved at 750 degrees C and with LSF loads between 20% and 40%. Equivalent circuit analysis of the EIS results indicated that the reactivity at the LSF/gas interface is rate-determining.

Summary: The emergence of fused ring electron acceptors has improved the power conversion efficiency of organic solar cells. However, the development of cathode interlayers lags behind and limits device performance. This study demonstrates the effectiveness of a hybrid cathode interlayer in improving device efficiency and provides insights for the selection and engineering of cathode interlayers.

Summary: Pure and manganese-doped ceria nanopowders were prepared using the sol-gel method, and their properties were characterized. The study found that manganese inhibits the grain growth rate of ceria, and doped samples have smaller crystallite sizes and greater specific surface areas. The catalytic efficiency of ceria was improved by doping with manganese, as demonstrated in the toluene oxidation test.

Summary: In this study, an insulating MgO blocking interlayer was introduced into PbZrO3 films to improve their breakdown strength and energy storage density. The results showed that the maximal endurable electric field was significantly improved, and the double-hysteresis characteristic disappeared after introducing MgO blocking interlayer. Low-temperature annealing was performed to suppress polarization loss, resulting in improved energy storage density and efficiency.

Summary: The study on lithium manganese phosphate with different chromium contents revealed that the dielectric constant increases with frequency at low chromium concentrations, while it decreases with frequency at higher chromium contents. The material with the highest chromium content showed the lowest AC conductivity and dielectric loss, making it suitable for various applications.

Summary: The study revealed that sulfur poisoning can occur in cathode materials even without alkali earth components. Sulfur readily reacts with La2O3 in the cathode material to form La2O2SO4 at different temperatures, highlighting the temperature dependency of the chemical reaction. This prompts the exploration of new materials and strategies for developing cathode materials with high sulfur tolerance.

Summary: This paper discusses an alternative sintering method to replace the conventional thermal sintering step for ceramic thin film fabrication in order to commercialize solid oxide fuel cells. By adopting the flash light sintering method, the post-heat treatment process time can be significantly reduced while achieving a 2-fold enhancement in fuel cell performance. Various material characterizations and analyses were conducted to validate the success of the fabricated SDC cathodic functional layer.

Summary: Solid-state lithium metal batteries (SSLMBs) using high-nickel layered cathode of LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) combined with solid polymer-based electrolyte (SPE) have attracted researchers' interest. However, the physical contact between NCA cathode and solid electrolyte is insufficient, leading to high contact resistance and non-uniform delithiation/lithiation kinetics. A design strategy of modifying the NCA surface with a fast ion-transport interlayer is proposed to enhance the ion-transport kinetics and improve the practical application of SSLMBs.
