Summary: The kinetic behavior of esterification between methacrylic acid and methanol catalyzed by NKC-9 resin in a fixed bed reactor was studied. The reaction was conducted at temperatures ranging from 323.15 to 368.15 K with a molar ratio of reactants from 0.8 to 1.4 under certain pressure. Three different kinetic models were used to fit the experimental data, and the Langmuir-Hinshelwood model showed the best fitting results. The stability of the NKC-9 resin was evaluated through long-term operation, showing no decrease in the yield of methyl methacrylate during 3000 hours. The structure and physicochemical properties of the catalyst were analyzed using various characterization techniques.

Summary: This paper proposes the use of monovalent selective electrodialysis technology to concentrate the valuable sodium chloride (NaCl) component present in seawater reverse osmosis (SWRO) brine for direct utilization in the chlor-alkali industry. Ionic exchange membranes (IEMs) were modified using interfacial polymerization (IP) to enhance monovalent selectivity. The IP-modified IEMs exhibited higher divalent rejection rate and enabled successful concentration of SWRO brine to 14.9 g/L NaCl.

Summary: Precisely controlling the interfacial contact and spatial transfer of photoexcited charge carriers is crucial for improving photocatalytic efficiency. In this study, a novel lotus seedpod shaped Cu2O/g-C3N4 p-n heterojunction composite was synthesized by filling the g-C3N4 framework with Cu2O hollow nanospheres. The obtained composite exhibited superior photocatalytic H-2 evolution activity, with a maximum production rate of 637.5 μmol g(-1) h(-1), 40 times higher than that of pure g-C3N4. The enhanced photocatalytic activity of Cu2O/g-C3N4 was attributed to the optimized p-n heterojunction structure and suitable heterojunction interface, which improved the spatial separation of photoexcited charge carriers and promoted charge transfer efficiency. This study highlights the potential of rational construction of p-n heterojunctions with ideal interfacial contact and intelligent regulation of spatial separation of photoexcited charge carriers for photocatalytic water splitting applications.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
