Summary: A continuous-flow electrohydraulic plasma discharge (EHPD) process was developed and investigated for degrading methylene blue (MB) in water. The study showed that complete degradation of MB was achieved within a short treatment time under optimal liquid and air flow rates. Hydroxyl radicals were found to be the main reactive species responsible for MB degradation, and high COD removal rates were observed, demonstrating the effectiveness and robustness of the EHPD reactor in degradation and mineralization of MB.

Summary: In this study, graphitic carbon nitride (GCN) decorated manganese oxide (Mn2O3) materials with different concentrations of GCN were synthesized and used for photocatalytic degradation of methylene blue (MB) contaminant. It was found that 60% GCN decorated Mn2O3 showed excellent photocatalytic performance with over 99% capability for MB breakdown. The improved photocatalytic activity was attributed to good crystallinity, defined shape, superior optical band gap, and smaller particle size.

Summary: Cu-doped SnSe powder was synthesized by hydrothermal method, and the degradation effect of different doping concentrations on methylene blue was investigated. It was found that low doping concentrations did not show obvious degradation effect due to Cu dissolution in the SnSe lattice. With increasing doping concentration, SnSe transformed from a layered structure to a nanocluster structure with reduced particle size, and a mixed phase of SnSe and Cu2SnSe4 appeared. The catalytic degradation effect on methylene blue was significantly enhanced, and the best performance was achieved at a doping concentration of 10 wt.%.

Summary: The growing population has caused an increase in water contamination, prompting the development of an efficient and eco-friendly catalyst to remove pollutants from water bodies. This study presents the development of a Sm-doped Fe2O3 photocatalyst through a low-cost sol-gel route for degrading methylene blue under sunlight. Various characterizations were conducted to analyze the photocatalyst, confirming the successful doping of Sm and the enhanced photocatalytic performance attributed to structural variations and efficient charge carriers separation/transportation. The synergistic photocatalytic performance of the doped catalyst proves its potential in water remediation.

Summary: This study demonstrates the direct removal of methylene blue (MB) using peroxymonosulfate (PMS) as an advanced oxidation process. The efficiency of MB removal reached 76% within 180 minutes. Factors such as PMS dosage, temperature, and pH influenced the degradation of MB, while MB concentration showed no effect. The reaction rate constant of PMS with MB varied with pH, and PMS could catalyze chlorine degradation at high chloride concentration.

Summary: This study reports the use of bacterial cells for the biosynthesis of Au@TiO2 as an efficient catalyst for the degradation of methylene blue. The bio-Au2@TiO2 catalyst showed the highest catalytic activity with a kinetics constant of 0.195 min(-1), and maintained stable activity for up to 10 cycles. The presence of Au nanoparticles on the bio-TiO2 layers decreased the band gap energy of TiO2, leading to the generation of abundant photogeneration hydroxyl radicals and enhanced photocatalytic activity.

Summary: In this work, NiFe2O4@NiO (1:0, 0.9:0.1, 0.7:0.3, 0.5:0.5, and 0:1) nanocomposites were prepared using a co-precipitation process to investigate their structural, dielectric, and optical properties for potential application in wastewater treatment. XRD, FTIR spectroscopy, and TEM were used to study the structural and morphological properties. The particle size was found to increase with nickel oxide content, and the oxidation state was determined using XPS. The impedance, dielectric constant, dielectric loss, and ac conductivity were observed to increase with nickel oxide concentration. The (0.5NiFe(2)O(4)/0.5NiO) nanocomposite exhibited the highest photocatalytic activity, degrading 95.41% of methylene blue dye within 120 min.

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.
