Summary: In this study, supported catalysts V2O5/3D g-C3N4 were prepared using a solvothermal method and programmed calcination, with a vanadium-based ionic liquid (V-IL) [(C8H17)3NCH3]3H3V10O28 as the vanadium source and 3D porous carbon nitride (3D g-C3N4) as the carrier. The use of V-IL promoted the high dispersion of V2O5 on the carrier and effectively avoided agglomeration. As a result, the catalytic oxidative desulfurization activity of V2O5/3D g-C3N4 was greatly enhanced, reducing the content of dibenzothiophene in model oil to 1.2 ppm under appropriate conditions. The recycling capacity and the possible process of oxidative desulfurization were also discussed.

Summary: This research paper focuses on the physicochemical optimization parameters for the Microwave Assisted Extractive/Oxidative Desulfurization (MAEOD) of Algerian diesel. The study used vanadyl acetyl acetonate as catalyst, hydrogen peroxide as oxidant, and an acid Bronsted Ionic Liquid (IL) as an in situ synthesized extractor. The researchers examined the effects of various parameters and developed a regression model to simulate optimal conditions. The highest yield was achieved with a reaction time of 70 s, a catalyst/oil ratio of 0.4%, and an IL/oil volume ratio of 11%, with a correlation of 99.21.

Summary: This study investigated the cytotoxicity of chemically relevant imidazolium PILs with different alkyl side chains and compared it with aprotic analogues. The results highlighted the role of anion type in determining the cytotoxicity of ILs with short alkyl side chains. Even low-toxic PILs showed harmful effects on eukaryotic cells when used as cryopreservation agents, and the studied IL/water mixtures tended to form simple solid hydrates due to the weak amphiphilic properties of imidazolium cations with short alkyl side chains.

Summary: Due to stricter environmental requirements, wide desulfurization has become crucial for obtaining ultra-clean fuels with low sulfur content for transportation purposes. In this study, a novel composite catalyst of [(FeW9O34)2 Fe4(H2O)2]-10 Fe6W18O70 cluster incorporated zirconium ferrite (ZrFe2O5) was developed to effectively remove sulfur. The structural properties of the catalyst were examined using various techniques, and Ultrasound assisted oxidative desulfurization (UAODS) processes were carried out to evaluate its performance. The catalyst Fe6W18O70@ZrFe2O5 achieved a sulfur removal rate of 98.2% within 40 minutes and could be regenerated multiple times without loss of activity. The reaction mechanism of the UAODS process was also investigated.

Summary: This article reports a novel porous phosphomolybdate-based poly(ionic liquid) catalyst with 70% water (PDIM-PMo-W70%). The catalyst showed a turnover frequency (TOF) value of 41.15 h-1 for dibenzothiophene (DBT) removal, which was 35.47 and 9.92 times higher than that of HPMo and PDIM-PMo, respectively. The effects of water content, reaction temperature, H2O2/S molar ratio, catalyst dosage, and different sulfur-containing compounds on the oxidative desulfurization (ODS) performance were investigated in detail.

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.
