Summary: Currently, the majority of oil-water separation membranes are made of fluorine-based polymers with low surface energy. However, these materials are non-biodegradable and require a large amount of organic and toxic solvents in the manufacturing process. Therefore, there is increasing interest in developing a new eco-friendly oil-water separation membrane that does not cause secondary pollution and exhibits selective wettability characteristics.

Summary: In this study, carbon particles were adsorbed on the surface of stainless steel meshes (SSMs) to form a thin hydrophobic coating, and a rough structure was then constructed through chemical vapor deposition and high temperature calcination, with the resultant SSM surface wrapped with uniform silica coating possessing superoleophobicity-underwater. The prepared SSMs exhibited superhydrophilicity in air and superoleophobicity-underwater. They showed high separation efficiency (above 98.8%) and separation flux (46,300 L·m(-2)·h(-1)) for oil/water mixtures. Immersion in different solutions did not significantly affect their separation efficiency (above 97.3%), and further immersion in dopamine and octadecylamine solutions transformed the SSMs into superhydrophobic SSMs with reverse surface wettability, which also exhibited good separation efficiency and separation flux for oil/water separation.

Summary: In this study, a multifunctional membrane (TCPP/UiO@SSM) was fabricated for gravity-driven oil-water/seawater mixtures separation and visible-light-driven bacterial inactivation. The membrane demonstrated high permeation flux and separation efficiency, thanks to its rough hierarchical structure and super-wettability. It effectively dealt with viscous oil fouling and demonstrated superior oil-water separation and photocatalytic sterilization performances compared to UiO@SSM. The doping of photosensitive TCPP in UiO-66-NH2 improved hydrophilicity and enhanced photocatalytic activity. This work provides a new platform for water disinfection and treatment of oily wastewater.

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.
