Summary: A non-swelling OGR membrane with fixed nanochannels was successfully prepared and demonstrated ideal separation of Cs+ and Sr2+ in multicomponent acidic waste. Compared to GOM, OGRM showed a higher water flux. This preparation strategy is crucial in overcoming the paradox between selectivity and flux, and is useful in remediating radioactive pollution and ensuring water security.

Summary: The performance of x-ray free electron lasers and ultrafast electron diffraction experiments relies on the brightness of electron sources from photoinjectors. High quantum efficiency (QE) cathodes like alkali-antimonide thin films can mitigate the effects of non-linear photoemission on mean transverse energy (MTE) of emitted electrons. By growing high QE Cs3Sb films on lattice-matched substrates, smoother and chemically uniform surfaces can be achieved, leading to higher brightness.

Summary: This paper investigates the adsorption regularities and mechanisms of nonradioactive Cs(I) and Sr(II) analogs on bentonites with different chemical and mineral composition. The main mechanism is ion exchange, leading to the formation of outer-sphere complexes and, at higher pH values, inner-sphere complexes. Bentonite T exhibits higher adsorption capacity compared to other bentonites.

Summary: Zeolites with high Si/Al ratios exhibit enhanced affinity to Cs+ ions, while zeolites containing 8-membered rings show extra-high selectivity for Cs+. In contrast, the affinity of Sr2+ ions to zeolites decreases as the Si/Al ratio increases, and Sr2+ exchange is less dependent on zeolite structures due to strong hydration. The kinetics of Sr2+ exchange is slower than that of Cs+ exchange due to the bulkiness of hydrated Sr2+ ions, with larger micropore channels beneficial for faster exchange kinetics.

Summary: This study investigated the penetration of Cs-137, Sr-85, and Eu-152 solutions into various common building materials and demonstrated the effectiveness of water in removing contaminants from hard nonporous surfaces. The concept of a wash penalty factor was introduced to quantify the depth at which contamination penetrates into the material, aiding in assessing the difficulty of decontamination with different washing methods.

Summary: The Chernobyl nuclear disaster released large amounts of radionuclides, which can still be detected in plants and sediments today. This study focused on moss samples from different locations and found high concentrations of Cs-137 and Am-241, with Cs-137 being significantly higher in the cooling pond. The results suggest that mosses accumulate radionuclides indiscriminately, while Cs-137 can be washed out from the soil over time, Am-241 remains adsorbed to the topsoil and precipitates in the cooling pond.

Summary: The possibility of using composite sorbents based on natural and synthetic zeolites for a mixture of cesium, strontium, and cobalt cations was investigated. The most effective composite sorbent was a combination of clinoptilolite and NaX zeolite with a ratio of 50% each, showing high sorption capacity for cesium, strontium, and cobalt. A technique based on the PIXE method was developed for qualitative and quantitative assessment of cation content.

Summary: The application of stabilization technologies can reduce the spread of radiological contamination and decrease worker exposure to radiation. Three stabilization technologies were investigated to evaluate their ability to reduce resuspension and tracking of contamination during response activities. The results showed that the stabilization technologies provided improved stabilization, with varying effects depending on the type of surface and worker actions. The technologies also decreased the availability of respirable particles for response workers.

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.
