Summary: Hierarchical hollow CuO/Cu2O and Cu2O/Cu/C composites are successfully constructed by calcining hierarchical tubular MOF in different atmospheres. The as-prepared hollow CuO/Cu2O is composed of nanosheets with a diameter of 20-30 nm, while the hierarchical hollow Cu2O/Cu/C is composed of larger particles with a diameter of about 65 nm. Selecting suitable MOF as sacrificed template and calcining in effective atmosphere provide a facile strategy for constructing derivant with functional structures and increased properties.

Summary: In this study, monolithic Cu2O-CuO/Cu catalysts were prepared by in situ thermal oxidizing-reducing copper foam. The obtained catalyst exhibited high catalytic activity towards O-3 removal, which can be attributed to the generated Cu+/Cu2+ redox couples, the donor/acceptor-type point defects, and the Cu2O-CuO p-p heterojunction. This research is of great importance for rapid, controllable, and productive O-3 removal applications.

Summary: A simple oxidation method was used to prepare CuO nanodisks on a flexible Cu sheet, with the crystal structure and surface morphology analyzed using various techniques. The in situ transformation of nanodisk surface after recycling accelerated dye degradation due to electron transfer. Efficient charge carrier separation was observed in the photodegradation system of Cu/CuO nanodisks, which was attributed to the generation of superoxide radical under daylight irradiation.

Summary: A study conducted on Qinghai Lake in China, the largest brackish lake on the Tibetan Plateau, found that the distribution of microplastics (MPs) with size <5 mm varied from the lakeshore to the center. The distribution was influenced by river inflow, tourism, and minimal human activity. Qinghai Lake was classified as moderately polluted with MPs based on the abundance in the sediments. The dominant characteristics of MPs in the sediments were transparent, fiber-shaped polypropylene.

Summary: Dynamic processes of organic contaminants in sediments have toxicological implications in aquatic systems. The study used DGT devices to measure the flux and exchange rates of antipsychotic compounds in sandy sediments. The results showed the continuous removal of these compounds from the sediments and their movement to the adjacent sediment solution. A dynamic model was used to determine the rate constants and distribution coefficients of the antipsychotics. The study highlights the importance of understanding the desorption kinetics of contaminants in sediments.

Summary: This study evaluated the toxic potency of PFECHS, an emerging PFAS, on zebrafish embryos and its potential effects in aquatic environments. The results showed that PFECHS caused fewer mortalities than PFOS in both acute and chronic exposures but resulted in a similar incidence of deformities. Exposure to PFECHS also increased the levels of specific genes at concentrations relevant to the environment. These findings provide insights into the safety of emerging PFAS alternatives in the aquatic environment and highlight the potential similarity of effects with legacy PFASs.

Summary: Breast cancer is the most common and deadliest cancer in women worldwide. Tamoxifen is widely prescribed for estrogen-receptor-positive breast cancer and has both anticancer and chemo-preventive effects. This review focuses on the potential importance of vitamin E in breast cancer chemo-prevention and how it can affect the actions of tamoxifen. The findings suggest that individually designed nutritional interventions with vitamin E should be further considered for breast cancer patients.

Summary: Major aryl hydrocarbon receptor (AhR) agonists were identified in the blubber, liver, and muscle extracts of six long-beaked common dolphins and one fin whale collected from Korean coastal waters. The concentrations of these agonists were higher in the blubber and liver extracts, showing tissue-specific accumulation. Five new polar AhR agonists were also identified, and they have the potential to biomagnify in the marine food chain.

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.
