Summary: In this study, the formation of the anomalous Hanle effect in a self-assembled quantum dot was investigated using experimental and theoretical approaches. The buildup time of the nuclear field was found to increase with increasing applied transverse magnetic field strength. Additionally, the inversion of the circular polarization degree of photoluminescence was observed to occur much faster than the buildup time of the nuclear field, indicating the importance of the in-plane component of the major principal axis of nuclear quadrupole interaction.

Summary: In this study, the photophysical characteristics of core/shell InP/ZnS quantum dots (InP-QDs) were analyzed in cell culture medium, salt solutions, and directly in the cells. It was found that InP-QDs were internalized into endolysosomes in HeLa and A549 cells with similar dynamics to Cd-based QDs, but the two cell lines accumulated them differently. InP-QDs were reliably detected in the endosomes despite their low quantum yields. Factors such as cell culture medium, acidic pH, and salt solutions were found to affect the photoluminescence lifetime of InP-QDs. The scatter between endosomes in the same cell was observed, indicating the complex impact of these factors on the state of InP-QDs. The toxicity of InP-QDs for both cell lines at concentrations higher than 20 nM was demonstrated.

Summary: Lateral flow immunoassay (LFIA) is a widely used rapid detection technology in the areas of food safety, environmental monitoring, and clinical diagnosis. The conventional LFIA based on gold nanoparticles (AuNPs) suffers from low sensitivity. In contrast, fluorescence LFIA (FLFIA) using quantum dots (QDs) as signal labels shows higher sensitivity. This review systematically summarizes the emerging strategies of tailing QDs to enhance the sensing performance of LFIA and provides insights into the future development of QDs-based LFIA.

Summary: A paper-based cell-counting method utilizing a blocking competition strategy was developed, along with a time-resolved fluorescence-blocking competitive lateral flow immunoassay (TRF-BCLFIA) for CD8 cell counting. This approach can provide an accurate CD8 cell count for whole-blood samples within 30 minutes and shows potential as a cost-effective alternative in community clinics, small hospitals, and low-resource regions where standard flow cytometry-based tools are not readily available.

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: 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.
