Summary: In this study, activated carbon treated in N2 atmosphere was used as a non-metallic catalyst for the reduction of Cr (VI) to Cr (III) using HCOOH as the reducing agent at room temperature. The improved catalytic performance was attributed to the enhanced graphitization degree and basic sites, which facilitated electron transfer and activation of reactant. The reaction rate constant observed for C-800 was significantly higher than that for C-0 and Pd/C catalysts. Furthermore, C-800 exhibited good recycle performance with no loss of activity after 5 cycles.

Summary: Herein, a mild protocol for the reductive functionalisation of quinolinium and isoquinolinium salts is disclosed. The reaction can proceed without transition-metal catalysts or with very low catalyst loadings. Formic acid is used as the terminal reductant. Various electrophiles can be intercepted by the in situ formed enamine species, resulting in a wide range of substituted tetrahydro(iso)quinoline compounds. The reaction also enables the synthesis of complex polycyclic products through annulation reactions.

Summary: In the past decade, significant advances have been made in the use of metalloporphyrins as catalysts for the activation and reduction of small molecules, particularly O-2 and CO2. The development of new molecular designs, scaling relationships, and theoretical modeling has rapidly advanced the utility of porphyrins as electrocatalysts. Emphasis is placed on contrasting homogeneous and heterogeneous electrocatalysis and proposing ideas for the development of practical catalysts based on lessons learned from the last decade of research.

Summary: In this study, sulfide-modified metal silicates (S-CoSi) were synthesized and applied in the PI-AOPs system to improve the catalytic performance. The sulfurization in metal silicate increased the specific surface area and charge transfer efficiency, enhancing the degradation performance. Experimental and calculation results showed that Co was the active site in S-CoSi, and sulfur species assisted in Co (II) regeneration and promoted the generation of 1O2.

Summary: This review explores the use of potassium hydroxide (KOH) in the production and modification of activated carbon. The activation process, carbonization, temperature, activation time, and KOH ratio are discussed, as well as their effects on surface area, surface morphology, and functional groups. The study finds that the pore structure, surface area, and pore size of activated carbon depend on the ratio of KOH, indicating that KOH influences the surface chemistry of the material. Additionally, the review calculates and evaluates the impact of various parameters on sorbent-sorbate interactions.

Summary: In this study, highly oxidized activated graphene (SOAG) materials with abundant carboxylic groups on the surface were successfully produced, which showed extremely high sorption capacity for U(VI) with a maximum capacity of 5400 μmol/g. This is an 8.4-fold increase compared to non-oxidized precursor activated graphene, a 50-fold increase compared to standard graphene oxide, and twice higher than extremely defect-rich graphene oxide. These findings provide a new approach to enhance sorption by achieving similar oxidation degree with less sacrifice of surface area.

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.
