Symmetric solid oxide fuel cells (SSOFCs) have emerged as promising energy conversion devices due to their low fabrication cost and outstanding durability. Ammonia (NH₃), a carbon‑free hydrogen carrier with high energy density and ease of storage, serves as an ideal fuel for such systems. In this study, a bifunctional electrode material, Pr_0.32Sr_0.48Fe_0.75Ni_0.2Ru_0.05O_3-δ (PSFNRu), is synthesized by doping 5 mol% Ru into the parent perovskite Pr_0.32Sr_0.48Fe_0.8Ni_0.2O_3-δ (PSFN). The resulting PSFNRu exhibits abundant oxygen vacancies and enables the in‑situ exsolution of alloy nanoparticles (ANPs) under reducing conditions, which act as additional active sites to enhance electrochemical performance. The PSFNRu‑based SSOFC delivers peak power densities of 736 mW cm^-2 with H₂ and 547 mW cm^-2 with NH₃ at 800 °C, significantly outperforming its undoped counterpart. Furthermore, the cell maintains stable performance for over 172 h at 700 °C under NH₃ fuel, confirming excellent operational durability. These findings underscore the potential of PSFNRu as a high‑performance symmetric electrode for direct ammonia SSOFCs (DA‑SSOFCs).

The overall energy efficiency is critical for commercializing promising electrochemical technologies such as the CO₂ reduction reaction (CO₂RR). Despite the rapid development of advanced catalysts and reactors for CO₂RR, its commercial potential is still hindered by the sluggish oxygen evolution reaction (OER), which causes high cell voltages and low energy efficiencies. Herein, we have developed a NiOOH@Ni₃S₂ catalyst on the surface of nickel foam (NF) via an electrochemical surface reconstruction strategy. We observe that the oxidation of glycerol to formate is more thermodynamically favorable than the OER on the developed NiOOH@Ni₃S₂/NF catalysts. The Ni²⁺/Ni³⁺ redox couples within the NiOOH@Ni₃S₂ heterojunction enhance the charge transfer kinetics between the active sites and adsorbed reaction intermediates, facilitating the highly selective and active generation of formate from glycerol oxidation reaction (GOR), with a remarkable Faradaic efficiency (FE) of 94% achieved at 100 mA cm^-2. Comprehensive mechanistic studies identified that the reaction pathway towards formate generation starts from glyceraldehyde intermediates and the glycolate was considered as the key species. Moreover, benefited from the efficient conversion of CO₂ to formate on bismuth nanosheets, the GOR//CO₂RR paired electrolysis system realizes a remarkable overall FE of ca. 190% for formate co-production at 160 mA cm^-2 (cathodic FE: 91.25%; anodic FE: 98.70%). This proceeds at a cell voltage of ca. 2.32 V, which is ca. 0.85 V lower than that of OER-assisted CO₂RR system at the same current density. This work provides new insights for co-upgrading CO₂ and biomass to value-added chemicals.

Since the Corona era, people's interest in health management has increased significantly compared to before. In addition, the emergence of multidrug-resistant bacteria through antibiotics has begun to have a great impact on human health. Therefore, the research team would like to report the synergy effect of antibacterial activity using wearable organic light-emitting diodes and natural antibacterial substances against staphylococcus aureus. This is research on a platform that is more convenient than past treatment methods and can suppress the development of multidrug-resistant staphylococcus aureus.
