Summary: The catalytic pyrolysis of sewage sludge with self-derived char was investigated in this study. The results showed that char reforming improved the quality of bio-oil by increasing the aliphatic content and reducing the organic nitrogen species content. The temperature of reforming had an impact on the yields of bio-oil and gas, with the highest aliphatic content and lowest organic nitrogen species content obtained at 500 degrees C.

Summary: In this study, MnOx loaded biochars derived from waste tea leaves were fabricated and demonstrated excellent degradation efficiency of 2,3,5-trimethylpyrazine (TMP) through heterogeneous catalytic ozonation (HCO) process. The active sites responsible for the HCO activity were identified as Lewis acid sites, including multivalent Mn sites, oxygen vacancies, and surface hydroxyl groups. Mn-nWT catalysts showed superior HCO activity compared to bulk biochar and MnOx. The impacts of water matrices on the Mn-5WT HCO process were thoroughly investigated.

Summary: Highly reactive MgO nanoclusters supported on sewage sludge-derived hierarchical porous carbon were successfully prepared by surface modification and dynamic chemisorption method. The smaller MgO nanoclusters showed higher catalytic activity towards ozonation of 4-chlorophenol and improved removal efficiency of pharmaceutical pollutants. DFT calculations indicated that the under-coordinated Mg in nanoclusters played a key role in activating ozone molecules.

Summary: MnOx has received widespread attention in low-temperature catalytic oxidation of VOCs, but the synergy effect of MnOx and support on the VOCs catalytic ozonation has been rarely studied. In this study, different MnOx/X materials were synthesized and it was found that the support greatly affects the catalytic oxidation activity. MnOx/MCM-41 exhibited the best catalytic activity, completely degrading O3 and VOCs at room temperature. Moreover, MnOx/MCM-41 showed strong water resistance and stability. The supply of loading sites and the improvement of interfacial electron transfer are the manifestations of the synergy between the support and MnOx in promoting the catalytic ozonation of VOCs.

Summary: Chemically activated waste activated sewage sludge showed potential for Pb(II) adsorption, with ZnCl2 activation significantly increasing adsorption capacity and surface area without changing the surface structure. However, HCl and H2SO4 activation ceased the adsorption process. Additionally, cationic exchange with hydrogen, calcium, and zinc was identified as a significant mechanism for Pb(II) removal.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

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: 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.
