Summary: The study directly observed a photochemical reaction occurring at the air-water interface using ultrafast phase-sensitive interface-selective nonlinear vibrational spectroscopy. The results showed that the reaction rate at the water surface is 10^4 times faster than in the bulk aqueous phase, indicating significant differences in photochemical reactions between water interfaces and bulk water.

Summary: In typical aqueous systems, multiple ion species are co-solvated, and these ions at the water-air interface can have significant impacts on chemical reactivity, aerosol formation, climate, and water odor. Through sum-frequency generation spectroscopy, researchers have quantified the relative surface activity of two co-solvated ions and found that hydrophobic ions tend to be speciated to the water interface due to the presence of hydrophilic ions. The speciation of ions at electrolyte solution interfaces is determined by the solvation energy difference between the ions and the intrinsic surface propensity of ions.

Summary: Lakes play a significant role in the carbon cycles of inland aquatic systems, and meteorology has profound effects on CO2 exchanges between wetlands and the atmosphere. The Baiyangdian Lake in North China acts as a major CO2 sink, with temperature and evapotranspiration being the main driving factors. Precipitation and wind speed also influence CO2 sinks, with larger summertime precipitation inhibiting CO2 uptake. This study provides valuable insights into the variation of CO2 sink fluxes in wetlands under changing meteorological factors, contributing to a better understanding of global lake carbon fluxes.

Summary: Ocean waves have a significant impact on the air-sea momentum flux, causing both magnitude and directional differences between the ocean-side and air-side stresses. These differences are more pronounced in coastal areas and under specific wind and wave conditions.

Summary: This study demonstrates that the photodecomposition of perfluorooctanoic acid (PFOA) can be significantly accelerated by carrying out the process in microdroplets. The abundance of the air-water interface in microdroplets promotes the decomposition of PFOA, resulting in higher removal rates. The method shows high performance and universality in actual water matrices.

Summary: In this work, a hydrocode called Pagosa is presented for the first time to study the Richtmyer-Meshkov Instability (RMI) at an air/high explosive (HE) interface. Pagosa is expected to predict the entire deflagration-to-detonation transition (DDT) process in the future. The capability of Pagosa in solving these instabilities is evaluated by comparing its results with existing numerical solutions and experimental data.

Summary: The study investigated the adsorption process of sunflower protein extract at two air-water and oil-water interfaces, revealing a three-step mechanism. Initially, a diffusion-limited adsorption of proteins at interfaces occurs, followed by the formation of a three-dimensional saturated monolayer of proteins, and finally a thick layer expanding in the aqueous phase. The study also found that the adsorption mechanisms of proteins exhibit significant divergences at longer adsorption times.

Summary: In this study, the relationship between large interfacial macropores and localized corrosion of steel-concrete interface was investigated. The results show that large macropores are preferential sites for corrosion initiation and propagation in the presence of the same environmental factors. The rate of localized steel corrosion increases linearly with the logarithm of macropore volume.

Summary: Atomistic molecular dynamics simulations were used to investigate the distribution of self-ions (H+ and OH-) at the interface between a long-chain C16-OH alcohol monolayer and water. Contrary to the air-water interface, the hydroxide ion (OH-) was found to accumulate at the alcohol monolayer-water interface instead of the hydronium ion (H3O+). The OH- ions were stabilized at the interface due to favorable interactions with the alcoholic -OH groups, while the H3O+ ions did not show such stabilization. The coordination numbers of the self-ions indicated that around 50% of water neighbors were replaced by alcoholic -OH in the case of hydroxide ions, compared to only 15% for hydronium ions. Interestingly, the hydroxide ion acted as the H-bond acceptor, while the hydronium ion acted as the H-bond donor.

Summary: The study demonstrates that acceleration of a five-component spiro-pyrrolidine construction can be achieved in microdroplets and thin films, with deposition method and mild heating being crucial factors for product formation. Three key intermediates were identified by mass spectrometry to elucidate the tandem reaction mechanism. Additionally, hydrogen bonding was found to significantly reduce the energy barrier at the air-liquid interface.

Summary: Nanopore sensing using borosilicate glass nanopores shows promise in single-molecule detection due to low noise and cost-efficient fabrication. Experimental results demonstrate that lowering the submersion depth of the nanopores can lead to higher signal to noise ratios by reducing capacitive noise and increasing DNA capture frequency at the air-water interface. Overall, borosilicate glass nanopores are suitable for studying interfacial concentration gradients of molecules with a higher signal to noise ratio.

Summary: Research shows that ions have a strong correlation with the structure of hydrogen bonding at the air/water interface and in bulk water. Specifically, structure-breaking anions decrease hydrogen bonding at the interface, while structure-making anions have the opposite effect. None of the electrolytes studied significantly affect the orientation of water molecules at the interface.

Summary: In the late stages of the HIV-1 life cycle, the membrane localization and self-assembly of Gag polyproteins induce membrane deformation and budding. The release of the virion requires the interaction between Gag lattice and ESCRT machinery at the viral budding site, followed by the assembly of downstream ESCRT-III factors. However, the molecular details of upstream ESCRT assembly dynamics remain unclear. In this study, molecular simulations were used to investigate the interactions between Gag, ESCRT-I, ESCRT-II, and membrane, revealing the mechanisms by which upstream ESCRTs assemble at the viral budding site.
