Summary: Exsolution phenomena, utilizing the instability of perovskite oxides, have been debated as efficient synthesis routes for nanostructured composite electrode materials. High-resolution transmission electron microscopy investigations have revealed spontaneous phase separation and dopant-rich features in the as-synthesized thin film material, providing insights into the subsequent exsolution process under reducing conditions. The incorporation of defect structures results in a reduced particle density at the perovskite surface, potentially trapping nanoparticles in the oxide bulk.

Summary: The authors identify a dynamic site renewal and decay cycle, mediated by proton transfers involving proximal BrOnsted acidic OH groups, which operates concurrently with the Chauvin cycle and could address roadblocks associated with industrial metathesis processes. This cycle can be manipulated using small quantities of promoter olefins to drastically increase steady-state propylene metathesis rates, with negligible promoter consumption, showing potential applicability to other reactions. The increase in activity and reduction of operating temperature requirements were also observed on MoOx/SiO2 catalysts, indicating the broad scope of this strategy in addressing major challenges in industrial metathesis processes.

Summary: The study aimed to investigate the fate, bio-metabolism, and environmental risk of low-ring and high-ring PAHs under long-term irrigation with micro-polluted treated wastewater. Results showed that high-ring PAHs had higher attenuation and adsorption rates compared to low-ring PAHs, with adsorption, biodegradation, and rhizosphere effect playing significant roles in PAH reduction. Functional microorganisms like Pseudomonas, Mycobacterium, and Sphingomonas were found to be positively correlated with PAH degradation, particularly in the rhizosphere. Environmental risk prediction after ten years of irrigation indicated minimal potential risks, suggesting the feasibility of using treated wastewater for garden irrigation.

Summary: The study demonstrated that Cu- cysteine complexes and Cu2S were the main components of Cu in wastewater algae, while CuS was the predominant form in 220°C-hydrochar. Model compound experiments showed that Cu- cysteine could be converted into CuS, while Cu2S was stable during hydrothermal liquefaction. The positive Gibbs free energy indicated that the oxidation from Cu+ to Cu2+ cannot occur spontaneously. Cyclic voltammograms showed that hydrochar facilitated the oxidation of Cu2S due to its higher capability of electron acceptance.

Summary: The co-occurrence of nanoplastics with metal oxide nanoparticles and polycyclic aromatic hydrocarbons has been widely studied, yet little is known about their interactions and combined toxic effects. This research found that increasing the concentration of metal oxide nanoparticles led to aggregation of nanoplastics, while polycyclic aromatic hydrocarbons had no major impact on nanoplastic stability. The size of the nanoplastics played a role in genotoxicity, with smaller nanoplastics showing higher levels of DNA damage.

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.
