Summary: This study investigates the evaporation, micro-explosion, and interaction phenomena of a mixed fuel droplet group during heating. Experimental equipment is used to observe the biodiesel and ethanol droplet group with different component proportions. The results show that when the ratio of biodiesel to ethanol is 40:60, the micro-explosion intensity is the highest, and higher micro-explosion intensity leads to higher evaporation rate. A three-stage evaporation model is established, and it is found that the second stage has an average evaporation rate 28 times higher than the first stage and 32 times higher than the third stage.

Summary: Using the single droplet suspension method, this study investigated the effect of nitrogen flow rate on the micro-explosion characteristics of different blended types of droplets in laminar flow conditions. Experimental results showed that the nitrogen flow rate had a greater impact on high-boiling fuel in low one (H/L) droplets compared to low-boiling fuel in high one (L/H) droplets. The micro-explosion intensity and number increased first and then decreased with the increase in nitrogen flow rate for most droplet compositions, except for B20M80. The study provided valuable insights for understanding the micro-explosion mechanism of different blended types of droplets in different flow regimes.

Summary: In this study, the expansion and evaporation characteristics of ethanol-biodiesel mixed droplets were investigated under different coal slime particle content and different particle size using the single droplet suspension method. Experimental results showed that the addition of micron-sized slime particles increased the evaporation rate of the droplets. The total evaporation rate of the droplets increased with increasing slime particle content, with the shortest total evaporation time observed for fuel droplets containing 3% slime particles. The stable evaporation rate of the droplets first decreased and then increased, with the highest stable evaporation rate observed for droplets containing 1% coal slime particles. Furthermore, at the same particle content, droplets containing 60 μm slime particles exhibited the fastest evaporation rate.

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.
