Summary: Direct current (DC) electrocoagulation is effective in decolorizing indigo dyeing wastewater but has low chemical oxygen demand (COD) removal rate and high energy consumption due to electrode corrosion. To improve COD removal rate and reduce energy consumption, a peroxi-alternating current (AC) electrocoagulation (EC) system was developed. The study focused on the effects of power type, electrode combination, and process parameters on COD removal rate and decolorization rate, and investigated the COD degradation mechanism. Results showed that AC electrocoagulation enhanced floc adsorption capacity and achieved a COD removal rate of 51.19%. The coupled peroxi-AC electrocoagulation system further removed sulfite and residual dyes, reaching COD removal and decolorization rates of 78.09% and 98.47%, respectively. The system also had significantly lower energy consumption compared to DC electrocoagulation, with a reduction of 70%. Overall, the peroxi-AC EC system is an effective method for reducing COD concentration in indigo dyeing wastewater.

Summary: The efficiency of combined electro-Fenton (EF) and electrocoagulation (EC) processes for treating mixed industrial wastewater was investigated in this study. The use of alkali modified laterite soil as a heterogeneous EF catalyst resulted in superior performance compared to raw laterite soil. By combining the EF process followed by the EC process, a high COD removal rate of 85.27% was achieved after 2 hours of treatment. The EF + EC strategy was found to be better than the EC + EF strategy in terms of nullifying the neutralization requirement, achieving high mineralization efficiency, enhancing biodegradability, and reducing sludge generation.

Summary: This study analyzes and designs a liquid phase esterification process using reactive pervaporation to convert acetic acid and isoamyl alcohol into isoamyl acetate with the help of a catalyst. By coupling a catalytic reactor with a separation membrane unit, the chemical reaction equilibrium is shifted towards the desired product by removing water. Through simulations and design charts, it is predicted that the integrated plug flow reactor-pervaporation reactor provides the best performance, with optimum ester yields as high as 0.94.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
