Summary: Metallic particles can inhibit the demetalation of Fe SACSs by acting as electron donors and strengthening the Fe-N bond, thereby preventing electrochemical Fe dissolution. Different types, forms, and contents of metal particles have varying effects on the Fe-N bond strength. Screening a particle-assisted Fe SACS resulted in a 78% reduction in Fe dissolution and enabled continuous operation for up to 430 hours in a fuel cell.

Summary: In this article, recent advances and challenges in achieving sustainable urea synthesis are discussed. The current method for urea production, the Bosch-Meiser process, relies heavily on fossil fuels and leaves a significant carbon footprint. Shifting towards photochemical or electrochemical processes shows promise for complete electrification of urea synthesis, but there are challenges related to catalyst design, electrolyte optimization, and reactor engineering. The adoption of renewable energy sources is also crucial for the environmental impact of urea production.

Summary: Transition metal oxide nanomaterials or nanocomposites containing transition metal oxides have the potential to replace traditional catalysts in electrochemical applications, photocatalysis, and energy storage. In this study, amorphous manganese oxide catalysts were prepared via photochemical metal-organic deposition (PMOD) and exhibited better performance than crystalline catalysts in terms of oxygen reduction and evolution reactions (ORR/OER). The addition of Ti4O7 during the PMOD process led to the formation of supported amorphous catalysts with improved stability. These amorphous catalysts showed better catalytic activity and performance in lithium-oxygen batteries compared to crystalline catalysts from previous work, attributed to their high defect state with more active sites.

Summary: A Co(II) complex with the polydentate quinol-containing ligand H2qp1 acts as an efficient electrocatalyst for oxygen reduction. It selectively produces H2O without any additional electron-proton transfer mediators, whereas a related complex that substitutes a phenol for the quinol instead produces mostly H2O2 under the same conditions.

Summary: The challenge lies in exploiting high-performance photocathodes to make narrow bandgap semiconductors feasible for efficient artificial photosynthesis. This study presents a highly efficient photocathode system based on a cuprous oxide semiconductor with a photonic crystal structure for good light harvesting, hole-transport layers that mediate and stipulate interfacial charge transfer, and a polypyrrole layer as a sequential multi-electron transfer agent. The integrated Cu2O photocathode achieves a record CO yield, high half-cell solar to CO efficiency, and optimal quantum efficiency, surpassing previous Cu2O based photocathodes. Moreover, the system exhibits operational stability for 7 hours. This work could guide the design and construction of efficient photocathode architecture for solar-driven CO2 reduction as a means of solar energy storage.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
