Summary: A porous core-shell copper hydroxy sulfate@metal-organic framework with surface decoration of 2,5-dimercapto1,3,4-thiadiazol was synthesized for the capture of Hg2+ using a self-template strategy, exhibiting superior adsorption capacity and selectivity. The adsorption behavior followed the Langmuir adsorption model, with a maximum adsorption capacity of 627.6 mg g(-1) for Hg2+ removal, and rapid capture of 99.96% Hg2+ within 10 minutes. XPS and Raman spectra confirmed the selective and strong interaction between Hg2+ and the functional groups on the modified MOF adsorbent.

Summary: The FLAG(R) tag (DYKDDDDK) is a small epitope peptide used for purifying recombinant proteins. Molecularly imprinted polymers (MIPs) selective to the FLAG(R) tag were developed as a cost-effective alternative to immunoaffinity-based adsorbents. These polymers were synthesized using an epitope imprinting approach and showed excellent recoveries and high specificity for both peptides when used as solid phase extraction materials. The magnetic properties of the polymers also provided a new, effective, simple, and fast method for purification using the FLAG(R) tag.

Summary: A novel coaxial hetero-structured MoS2/SnO2 nanotube array was designed for flexible visible light photodetection, achieving high photoresponsivity and external quantum efficiency through controlled deposition thickness and strain. The linear correlation between excitation power and photocurrent, as well as the superlinearity of photocurrent in the device, were observed, with density functional theory calculations revealing a strong correlation between strain, bandgap, and photocurrent. The study suggests a detailed mechanism for enhancing photoresponsivity in the strain-tailored nanotube arrays, which are expected to revolutionize smart optical devices with low driving voltage and high power efficiency.

Summary: Extensive modifications were made to a commercially-available cold-vapor atomic absorption mercury analyzer to enable fast and stable real-time Hg-0 detection under harsh conditions with additional HCl, NO, and NH3. The fully modified analyzer showed similar Hg-0 signals to those based on factory-certified permeation tubes. The oxidation activity of gaseous Hg-0 was found to be associated with the catalyst and influenced by the concentration of HCl in gas streams with NO and NH3.

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.
