Summary: This paper introduces a new method of fast elimination of cable fire smoke in underground tunnels using acoustic agglomeration technology. Experimental results show that with a certain frequency and acoustic power, the light transmittance of smoke can be rapidly increased from 10% to 60% within 60 seconds, reaching the threshold for safe escape in fire situations.

Summary: This study examines the agglomeration mechanisms in microscale droplet aerosols, particularly focusing on acoustic and turbulent agglomeration mechanisms. The analysis shows that orthokinetic and hydrodynamic processes have a significant impact on acoustic agglomeration. A specific frequency range of 50-250 Hz is identified for optimal orthokinetic agglomeration. Hydrodynamic agglomeration remains stable at frequencies exceeding 1000 Hz. The aggregation kernel function Kij increases with sound pressure levels and environmental temperature, but exhibits different effects on different agglomeration mechanisms.

Summary: Traditional methods for detecting fire smoke often miss thin smoke plumes and struggle to accurately differentiate smoke from dust, clouds, and bright surfaces. To address this issue, a new scattering-based smoke detection algorithm (SSDA) has been proposed, primarily relying on VIIRS blue and green bands. SSDA extracted training samples from fire-prone regions globally, outperforming existing products and demonstrating the capability to detect fire smoke plumes in near real-time globally.

Summary: This study examined the fire and smoke spreading characteristics in natural gas cabins of urban underground utility tunnels using computational fluid dynamics. Results show that oxygen in a 200m confined natural gas cabin can only sustain fire for 2.5 min, with high mechanical ventilation speeds being unfavorable for normal operation and maintenance.

Summary: A new photometric measurement method for determining light extinction coefficients in laboratory fire tests was presented. The method captures the change in intensity of individual light sources due to fire smoke using a digital camera. The approach is capable of accurately capturing the investigated phenomena, although it underestimates measurements in the infrared range. By evaluating multiple color channels of RAW image data, this deficiency was remedied. The study demonstrates the method's convenience and reproducibility as a tool for validating numerical visibility models, but further improvements are necessary to address uncertainties and enhance accuracy.

Summary: The Black Summer fire season of 2019-2020 in southeastern Australia led to a large-scale outbreak of fire-induced and smoke-infused thunderstorms known as pyrocumulonimbus, with over half of the pyroCbs injecting smoke particles into the stratosphere. These smoke plumes persisted for an unusually long time and continued into nighttime, impacting the climate and environment significantly.

Summary: This paper discusses the effect of introducing solid barriers at the ceiling of a tunnel on slowing down propagation of smoke resulted from a fire using numerical simulations. The study found that using solid barriers with specific design arrangements can significantly reduce smoke spread distance and improve visibility conditions in the tunnel. The findings confirm the advantages of using solid barriers and suggest future research directions to develop more knowledge on smoke barriers performance.

Summary: This study analyzed the temperature, velocity field, and visibility changes in subway carriages during fires using the fire dynamics simulator (FDS). The results showed that the distribution pattern of ceiling temperature and velocity field remains the same for different subway carriages fires.

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.

Summary: This study utilized Mo powder and STPP to enhance the performance of the sodium percarbonate system in pollutant degradation. The presence of Mo and STPP resulted in a higher degradation rate of the model pollutant SMX, with low oxidant consumption. The system generated multiple active species through a series of chain reactions at different pH values, exhibiting excellent performance towards electron-rich pollutants. Furthermore, Mo demonstrated excellent stability and reusability.
