Summary: The dissolution rates of CO2 hydrates in sediments were calculated under different diffusion stages, showing a rapid initial dissolution followed by a slowing rate due to decreasing concentration gradients. CO2 hydrates covered by sediments dissolved much slower than those in direct contact with water layers, indicating a strong dependency on velocity when exposed to flowing water layers.

Summary: Biochar has been widely used for immobilising trace metals (TM) in contaminated soils, but the research on the physicochemical mobility of TMs related to biochar application is limited. This study confirmed biochar's ability to reduce the bioavailability of Tl in soil and investigated the release of Tl in dissolved and particulate forms in surface runoff and leachate under rainfall and irrigation experiments. The results showed that biochar application decreased dissolved Tl in the surface runoff, with finer biochar achieving higher immobilisation ability and lower Tl amounts in the leachate. Rainfall disturbance enhanced Tl diffusion, and particulate forms accounted for most of the released Tl in surface runoff. Colloidal particles carried a significant amount of Tl in the rainfall leachate. Overall, this study contributes to a better understanding of biochar's role in TM remediation.

Summary: This study investigates the sorption behavior of bisulfide (HS-) onto bentonite, and finds that HS- sorption occurs faster and has a higher equilibrium sorption capacity at higher temperatures. The study also suggests that the irreversible sorption of HS- onto bentonite may be due to the chemical reactions between HS- and the iron present in bentonite, forming iron monosulfide (FeS). These findings provide critical information to better understand the sorption mechanism of HS- on bentonite and reduce HS- transport in deep geological repositories.

Summary: The thermal adsorption residue (TDR) derived from oil sludge co-contaminated soil was found to effectively neutralize acid substances and adapt to a wide pH range. It demonstrated high adsorption capacities for four heavy metals, namely As(III), Zn(II), Cu(II), and Cd(II). There was a competitive adsorption among the three cations on TDR, and the presence of As(III) lowered the adsorption capacity of Zn(II), Cu(II), and Cd(II).

Summary: The mechanical properties of quartz and its rheological behavior have been studied in this research. The flow law parameters of quartz have been constrained through constant-load experiments. The results show that the deformation of the quartz samples is mainly achieved by crystal plasticity, with grain boundary processes accommodating the strain incompatibilities induced by dislocation glide. The new flow law can accurately estimate strain rates, especially at low stresses, and predict a rapid drop in strength of quartz-bearing rocks at certain depths or temperatures.

Summary: This study examines the differences in the effects of local celebrity endorsement and endorsement by celebrities from tourist source countries in international destination marketing. The findings show that using a celebrity from the tourist source country significantly increases tourists' visual attention to the advertising destination scenery, positive attitudes towards the destination, and intentions to visit. Furthermore, a serial mediation model of celebrity endorsement, celebrity-tourist congruency, tourist attitude towards the celebrity, and tourist response is identified. The study also explores the moderating role of regulatory focus on the celebrity endorsement effect.

Summary: This study investigates the influence of anhydrite and barite scales on the surface charge and wetting state of calcite minerals. It was found that the presence of these scales affects the colloidal stability of the system but has an insignificant impact on surface charge and wettability. Continuous injection of EDTA solutions was determined as the optimal control strategy, with specific dosage recommendations for different scales.

Summary: Heavy and extra heavy oil exploitation has gained attention due to the decline in conventional crude oil production. The high viscosity of heavy crude oil poses a major challenge in its extraction. Catalytic aquathermolysis using acidic ionic liquids has shown to effectively reduce the viscosity of heavy crude oil at relatively low temperatures, improving its rheological behavior and chemical composition.

Summary: This study used optical imaging to investigate two-phase drainage in a heterogeneous micromodel under different injection rates and flow directions, and found that the capillary pressure-saturation relationship near a heterogeneity interface deviates from conventional models. The initial findings highlight the gaps in the understanding of upscaling capillary pressure in heterogeneous porous materials, and indicate that the discontinuity in saturation is more pronounced in the fine-to-coarse direction.

Summary: The dynamics of air flow in partially water-saturated, porous geological formations are influenced by various forces and parameters. Reliable gas-liquid flow models are important for understanding the role of gases in earth systems and engineering practices involving air injection. However, existing modeling approaches have limitations in capturing the complexity of air flow in wet porous media. Continuum models, such as Darcy's law, are suitable for single-phase flow in saturated media but not for two-phase flow. Pore-scale models require extensive computational efforts and lack accessible details on medium characteristics. Stochastically-based representations show limited success in interpreting phase configurations and saturation degrees.

Summary: The Indian summer monsoon has significant impacts on a large population. Precipitation extremes during the monsoon season are poorly understood, making it a challenge to accurately forecast and project future extreme events. This study reveals that the extremes are linked to dry air intrusions from southern midlatitudes, triggering intense ocean evaporation and modulating moisture transport patterns towards India. This leads to increased precipitation by more than 17% on average, but can also decrease rainfall over land depending on wind patterns.

Summary: Events of high dust loading are extreme meteorological phenomena with significant climate and health implications. Early forecasting is therefore crucial in mitigating their adverse effects. Dust modeling is a challenging task due to the complex coupling between atmospheric particles and the underlying atmospheric flow patterns. In this study, a meteorological-based deep multi-task learning approach is proposed for forecasting dust events, which shows promising results in detecting and predicting these events in Israel using regional meteorological data and machine-learning interpretability methods.

Summary: In this study, we investigate anomalous transport in a hydrological catchment system over a 36-year period at kilometer scales. Using spectral analysis, we examine the fluctuation scaling of long-term time series measurements of chloride, a natural passive tracer, for rainfall and runoff. The findings suggest that the scaling behavior can be described by a continuous time random walk (CTRW) based on a power-law distribution of transition times, indicating the presence of two distinct power-law regimes in the overall travel time distribution in the catchment. The CTRW framework provides a means to assess anomalous transport in catchments and its implications for water quality fluctuations.

Summary: By studying a speleothem sample from Peqi'in Cave in Israel and modern rainfall data, researchers reconstructed the temperature and rainfall source changes in the Eastern Mediterranean during the last interglacial period. The study found that as the Atlantic Meridional Overturning Circulation weakened, the rainfall source shifted from meridional to zonal air flow. The decreasing rainfall trends over the last 25 years raise the question of whether similar atmospheric circulation changes are occurring today.

Summary: This study investigates the relationship between rubidium concentration in amniotic fluid during the second trimester and newborn birthweight in the third trimester. The findings suggest that low rubidium concentrations in midpregnancy are associated with lower birthweight percentile. Therefore, rubidium concentration in amniotic fluid could serve as an important marker for early identification of pregnancy outcomes.
