Summary: This article investigates the mechanism by which impurities in n-propanol and ethylene glycol influence the explosion boiling of superheated liquids. Experimental results show that short chain alcohol impurities cause significant changes in pressure response, temperature response, and bubble nucleation evolution in storage tanks. These impurities also lead to changes in the two-phase flow evolution behavior during superheated boiling, promoting the explosive boiling of the superheated liquid. The density of bubbles increases, affecting the pressure and temperature responses during the release process inside the tank.

Summary: Accidental boiling liquid expansion vapour explosions (BLEVEs) caused by the bursting of liquified petroleum gas (LPG) tank inside a tunnel can induce vibrations of its surrounding geological media and threaten the stability of adjacent tunnels and structures. Understanding the characteristics of these vibrations is essential for the safety design of adjacent structures.

Summary: This study numerically investigates the dynamic response of an arched tunnel subjected to an internal BLEVE. The results show that the corner and upper arc of the arched lining are more prone to be damaged. Explosion loads estimated by the TNT equivalency method induce more significant damage to the lining but smaller peak displacements compared to the directly predicted BLEVE loads.

Summary: The evolution of two-phase flow, internal pressure, and thermodynamics responses during a BLEVE process with water were evaluated. It was found that increasing initial pressure initially leads to a higher rate of pressure rise, although this rate slightly decreases due to competitive effects between expansion flow and countercurrent flow. Countercurrent flow inhibits expansion flow, reducing boiling intensity, while pressure relief actions can intensify boiling explosions after crack formation.

Summary: In this study, nanoscale thin-film boiling on different surfaces was simulated, and it was found that the heat transfer performance of boiling depends on the surface properties. Rough structures improve the efficiency of boiling, while hydrophobic surfaces lead to heat transfer deterioration. The underlying mechanism is attributed to the variation of interfacial thermal resistance.

Summary: Accurate estimation of the maximum kinetic energy and trajectory of fragments is crucial in mitigating the hazards of explosions. A tanker truck carrying LPG exploded in China, providing an opportunity to study the 'rocket' BLEVE process and evaluate potential trajectory models. Using image analysis and 3D modeling, a precise trajectory of the fragment was reconstructed, with results fitting well with the predicted models.

Summary: This study investigated the boiling vaporization and breakup of single droplets of n-butanol, n-hexadecane and their binary mixtures with 10-50 w.t.% n-butanol. Experimental results showed that bi-component droplets exhibit strong two-phase flow instability, experiencing fluctuation evaporation between the transient heating and stable evaporation stages. The droplet vaporization characteristics gradually shift from normal evaporation to partial rupture or passive breakup, eventually leading to micro explosion and significantly reducing droplet lifetime.

Summary: This paper experimentally investigated the combined influence of artificial nucleation sites and expanding cross section on the saturated flow boiling performance of heat sinks with micro pin fins. The results showed that the novel heat sink design led to a significant improvement in heat transfer coefficient and a reduction in pressure drop compared to conventional heat sinks, due to factors such as liquid trapping, vacuum effect, and prevention of bubble blockage.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
