Summary: In this study, a dual regulation strategy was proposed to improve the performance of graphene oxide (GO) membranes for water treatment. The strategy involved the use of 1,4-Diaminobutane crosslinker to prevent swelling and maintain interlayer spacing, as well as the hydrophilic EMT-type zeolite promoter to enhance water permeability. The NH2-GO/10EMT composite membrane obtained showed enhanced water flux, dye rejection, structure stability, and fouling resistance, demonstrating its potential for selective water separation.

Summary: By chemically modifying the surface of graphene oxide (GO) using diazonium chemistry, we introduce nitrobenzene groups as interlayer pillars in GO membranes, similar to the oxygen-containing functional groups on the surface. The larger pillars effectively enlarge the interlayer space of the GO membrane, leading to improved filtration performance for dyes.

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.
