Summary: Earth-abundant transition metal catalysis has been developed as a viable substitute for noble transition metal catalysis in hydrogenation reactions. However, the hydrogenation of thioamides using earth-abundant transition metals has not been reported due to catalyst poisoning by sulfur-containing molecules. In this study, we successfully achieved manganese-catalyzed hydrogenative desulfurization of thioamides to amines or imines by employing MnBr(CO)(5) instead of commonly-used pincer-manganese catalysts, along with NEt3 and CuBr. This reaction demonstrated excellent selectivity in breaking the C=S bond of thioamides, unlike the only known Ru-catalyzed hydrogenation of thioamides, and it exhibited unprecedented chemo-selectivity towards vulnerable functional groups.

Summary: By using deep eutectic solvents (DES) as solvents, the desulfurization rate can be improved, leading to the production of nickel boride (NB) with small particle size and high specific surface area. Different DESs have a significant impact on the desulfurization rate of aromatic sulfides, and the structures of DESs remain unchanged after regeneration.

Summary: Defects in the basal plane of graphene are chemically active centers that can be controlled for functionalization with foreign molecules. A novel approach is reported to generate, monitor, and functionalize these defects in situ without exposure to ambient conditions. Experiments show that defects generated by argon plasma can be functionalized in situ, inducing n-doping in graphene with stable carrier density under ambient conditions.

Summary: A highly active composite catalyst (ZZO/Z5-SG) of ZnZrO and HZSM-5 was reported for xylene synthesis from CO2 hydrogenation in the presence of toluene, achieving a xylene selectivity of 86.5% and CO2 conversion of 10.5%. The catalyst exhibited a remarkably high space time yield of xylene (215 mg g(cat)(-1) h(-1)), surpassing most reported catalysts for CO2 hydrogenation. The enhanced performance of ZZO/Z5-SG could be attributed to high dispersion and abundant oxygen vacancies of ZZO for CO2 adsorption, close interaction between the two components for more feasible hydrogen activation and transfer, and enhanced stability of the formate intermediate.

Summary: This study proposes a waste control method to treat wastewater containing highly toxic Cr(VI) and sulfite. Through the redox reaction of Cr(VI)-sulfite, highly toxic Cr(VI) is converted into non-toxic substances and enriched on a novel biochar-induced cobalt-based silica composite. This method effectively reduces the harm to aquatic life and human health.

Summary: This study investigated the direct desulfurization reaction of domestic limestone samples in oxy-fuel circulating fluidized bed combustion. The results showed that the difference in CaSO4 conversion ratio by particle size was mainly due to the specific surface area. Additionally, the CaSO4 layer formed at a uniform thickness regardless of the particle size.

Summary: In this paper, a novel catalyst-free hydrogenation process using microsecond pulsed dielectric barrier discharge (DBD) was developed to convert gaseous toluene into methyl-cyclohexane at ambient pressure and room temperature. The hydrogenation performance of toluene was investigated, and the results showed that higher pulse repetition frequency, lower reactor temperature, and higher H2 concentration favored the production of methyl-cyclohexane.

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.
