Summary: In this study, a series of compounds containing low-valent central atoms were successfully synthesized using bis(NHSi) ligands with electronically and spatially different spacers. The chemical reactions and electronic structures of these compounds were investigated. By controlling the Si–Si distance, a variety of low-valent compounds of Si, Ge, and Sn elements were synthesized, and the o-carborane-based bis(NHSi) ligand enabled the oxidation of Si and Ge as well as the isolation of new compounds. Furthermore, future research directions were proposed, such as applying bis(NHSi) ligands to other main-group elements and developing acyclic silylene ligands.

Summary: This paper investigates the structural and spectral changes of mesoporous silica-coated gold nanorods (AuNRs@mSiO2) during Hg-Au amalgamation. The silica shell suppresses the deformation of the AuNR cores, resulting in unchanged aspect ratio. The localized surface plasmon resonance (LSPR) wavelength peak of individual AuNRs@mSiO2 exhibits a blue shift and strong plasmon damping when exposed to Hg solutions. Additionally, the inward diffusion of Hg into the AuNR core causes a gradual red shift and narrowing of the LSPR peak.

Summary: Mercury pollution in aqueous solutions is a significant environmental concern with potential health risks. This study presents a one-pot synthesis of a bis-Schiff base cellulosic adsorbent that combines large adsorption capacity and excellent fluorescent recognition for mercury ions. The adsorption experiments show specific affinity between sulfydryl-containing cellulosic nanocrystals and mercury species, with a high adsorption capacity of 624.8 mg/g at room temperature. The material also exhibits a 19-fold enhancement in selective fluorescence sensing when exposed to mercury. Additionally, the bifunctional adsorbent material demonstrates high sensitivity towards mercury ions in aqueous solutions with detection limits of 8.29 x 10-8 M for fluorescence and 5.9 x 10-9 M for UV-vis spectrum. The adsorption process follows a pseudo-second order kinetics and density functional theory studies offer insights into the adsorptive and responsive mechanisms.

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.
