Summary: This work developed a theoretical model to predict the diffusion process of hydrogen clouds in a crosswind field with an atmospheric inversion layer, and the model was validated by experimental results. The study revealed the importance of considering the crosswind field and atmospheric inversion layer in the diffusion of liquid hydrogen, as they can suppress cloud rise and affect cloud height and concentration.

Summary: This study compares the effects of lean combustion and exhaust gas recirculation (EGR) on the combustion behavior of hydrogen fuel. It is found that EGR dilution has a more significant impact on laminar burning velocity, while EGR dilution more effectively reduces the NO mole fraction in the final products.

Summary: The structure, dynamics, and vibrational spectroscopy of a water surface covered by a monolayer of stearyl alcohol (STA) are investigated. It is found that the STA-water interface is narrow with an ordered arrangement of STA molecules, resulting in a slowing down of the dynamics of interfacial water molecules.

Summary: In this study, the diffusion behavior of H2S in the H2S-H2O system was simulated using the molecular dynamics method. The self-diffusion coefficient of H2S was calculated under different conditions (pressure: 235-280 atm, H2S molar concentration: 1-5%, temperature: 600-1173 K). The results showed that the molar concentration and pressure of H2S had little effect on its self-diffusion coefficient, while temperature and water density had a greater effect. Additionally, the self-diffusion activation energy of the supercritical region of H2S was found to be only 32.58% of the subcritical region. Finally, new parameters of an empirical equation were fitted to predict the self-diffusion coefficient of H2S in the H2S-H2O system, with a mean relative error of 3.05% in the supercritical region.

Summary: This study investigates aerosol-cloud interactions over the North China Plain and north of the Yangtze Plain, finding that aerosol characteristics, atmospheric conditions, and drizzle all have impacts on cloud effective radius. Results show that the aerosol first indirect effect is negative for most cases when considering all clouds, but positive when only considering clouds without drizzle.

Summary: Terpenes are important compounds that contribute to the aromas of alcoholic beverages. This study investigated the vapor-liquid equilibrium (VLE) of alpha-terpineol in ethanol-water mixtures. The experimental data were correlated using different models, and the NRTL model showed the best agreement with the experimental results. These findings have implications for the design and simulation of distillation processes in the production of alcoholic beverages.

Summary: Perovskite SrIrO3 films and their heterostructures have great potential for exploring interesting physics resulting from the interaction between strong spin-orbit coupling and electron correlations. However, the synthesis of pure-phase SrIrO3 films using elemental iridium as a source presents challenges. In this study, we propose a novel solid-source metal-organic MBE approach to address these challenges and successfully grow phase-pure SrIrO3 films with unique physical properties.

Summary: This study used computational fluid dynamics modeling to investigate the airflow patterns and infection risks in an underground subway platform. The results showed that the interaction between ventilation jet and breathing jet posed the highest exposure risk to front passengers. However, pathogens were efficiently diluted as they traveled further. Different ventilation modes had an impact on infection risks, with the second mode minimizing the risks. Based on data of COVID-19 and influenza infectors, the predicted infection risks for passengers in the same crowd were sensitive to ventilation rate and exposure time.

Summary: This work focuses on the transient process of thermoacoustic oscillation in a standing-wave thermoacoustic engine with gas-liquid coupling oscillation. The on-off phenomenon can occur by adjusting the location of the stack in the acoustic field, and there exists a critical distance for this phenomenon to occur. Energy dissipation induced by liquid surface instability is a key factor contributing to the occurrence of on-off phenomenon. The significance of liquid surface instability on the transient process of thermoacoustic oscillation is revealed in this study.
