Summary: A nanoarchitectural strategy for designing highly active catalysts using CoMoS encased in 50-nm diameter aluminosilicate tubes as a natural support has been proposed. This encapsulation approach protects the active metal sulfides from aggregation, coking, and leaching. Experimental results indicate that the selective loading of molybdenum oxide inside the nanotubes using Mo-heteropolyacid anionic precursor complex leads to the formation of CoMoS particulate core inside the aluminosilicate shell, resulting in a mechanically strong mesoporous catalyst efficient for the hydro treatment of diesel petroleum fraction to clean fuels.

Summary: The catalytic efficiency of Pd@CeO2 catalyst supported by Halloysite was enhanced by hydrothermal carbonization. The catalyst with carbonized Hal showed higher catalytic activity due to the proportion of carbon and oxygen functional groups. Furthermore, combining alkaline modification with hydrothermal carbonization significantly reduced the conversion temperature of CO.

Summary: This study investigates the microwave absorption properties of Cu-C core-shell nanoparticles and their derivatives. It is found that the C shells significantly improve the polarization loss, while the Cu cores have negligible influences on the conduction loss.

Summary: In this study, carbon molecular sieving (CMS) membranes were fabricated using three different polymer precursor conformations: dilute, semi-dilute, and concentrated. The effects of the precursor conformation on the microstructure of the resulting CMS membranes were characterized by Raman analysis. A novel method combining HR-TEM and FIB systems was proposed to detect the cutoff size of the CMS membranes. The CMS membrane fabricated with a semi-dilute solution exhibited superior gas separation performance, with a high selectivity of H-2/CH4 and hydrogen permeability, surpassing reported permselectivity of other membranes.

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: 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.
