Summary: In this study, salts combining diclofenac with clofazimine were prepared using solvent crystallization and liquid-assisted grinding. Five solvated salts and one unsolvated salt were successfully crystallized. The ability of diclofenac anion to interact with protic molecules was exploited to crystallize a cocrystal of salt with drug in different ratios. Structures of solvated cocrystals with acetonitrile and ethylacetate, and unsolvated cocrystals combining clofazimine with diclofenac in 1:2 ratios, were determined.

Summary: Data on the potential impact of engineered nanomaterials on human health are limited, particularly in terms of exposure levels throughout their life cycle. Prioritizing responsible handling of nanomaterials can promote sustainability by reducing occupational exposure risks, protecting employees' well-being, minimizing liability, and avoiding expensive environmental remediation efforts. This study evaluates the risk of carbon-based nanomaterials in real scenarios, such as research laboratories, pilot-scale facilities, and industrial settings. Through various instruments, including scanning electron microscopy and energy-dispersive X-ray spectroscopy, the particulate matter in these environments, including nanoscale particles, was characterized for risk assessment. Exposure estimation was conducted using the nanoGEM methodology, and the handling of reduced graphene oxide in a pilot plant was identified as the activity with the highest risk of exposure. Additionally, high particle concentrations were found during the dispersion of carbon nanotubes and incorporation of carbonaceous nanoparticles into resins.

Summary: The fundamental and n = 3 overtones of Au nanoplate thickness vibrations were studied using transient absorption microscopy. It was found that the frequencies of the n = 3 overtone are lower than 3 times the frequency of the fundamental. This anharmonicity was explained by a continuum mechanics model that includes organic layers on top of the nanoplate and between the nanoplate and the glass substrate. The results suggest that engineering layers of soft material around metal nanostructures can be used to control the vibrational lifetimes.

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.
