Summary: Soil salinity and sodicity pose threats to plant growth and soil health, especially when using marginal quality water with high salt concentrations in agricultural systems. Models play a crucial role in understanding and managing these risks, allowing us to explore various future scenarios and predict the consequences of agricultural practices. This review examines advanced models that study how salinity and sodicity affect plant health and soil structure, with a focus on their integration into dynamic models to analyze evolving plant and soil responses under changing climate and irrigation conditions. The review also highlights the differences in complexity and suitability of existing modeling frameworks for integration into larger climate models, along with important applications of these models in studying salt leaching, ion chemistry, layered profiles, and long-term soil degradation caused by specific irrigation practices.

Summary: The study investigates the shear thinning behavior of non-colloidal suspensions with a focus on the effect of particle surface roughness. Two shear thinning phenomena are observed, with the first originating from particle-particle interaction and the second from polymeric solvent. Theoretical models are developed and experimental data support the findings, concluding the impact of roughness on rheological behavior.

Summary: This study investigates the transport mechanism of chromium (Cr) in contaminated soils and the effects of acid rain infiltration. The results show that soil colloids play a significant role in the adsorption and leaching of Cr, with different effects depending on the type of colloid. Humic acid (HA) colloids enhance the adsorption efficiency of Cr, while montmorillonite (Mt) colloids reduce it. Acid rain increases the leaching rate of Cr. The findings provide insights for the quantitative assessment of groundwater pollution risk caused by Cr in the vadose zone.

Summary: Surface roughness applied to cooling holes was found to increase boundary layer thickness, jet core flow, and decrease cooling effectiveness. The film cooling performance showed a significant reduction with higher levels of surface roughness in the cooling hole. Time-space evaluation indicated greater flow unsteadiness and wavy patterns within rough cooling holes.

Summary: The nonstationary nature of water and oxygen content in the vadose zone determines various biogeochemical reactions regarding arsenic (As) therein, which affects the groundwater vulnerability to As contamination at a site. In the present study, we evaluated the effect of soil organic matter (OM) on the behavior of As using specifically designed soil columns that simulated the vadose zone. OM was found to exhibit variable effects, either inhibiting or accelerating the mobilization of As, depending on bulk density.

Summary: The unsaturated zone of the subsurface plays a critical role in environmental fate and transport, as well as plant growth. Previous research suggests that the capillary pressure-saturation relationship is influenced by a dynamic equilibrium between capillary forces and phenomena driven by evaporation. This study further investigates the role of evaporation in this relationship, finding that evaporation affects the saturation of water in the unsaturated zone and exhibits seasonal variations.

Summary: This study establishes an improved transfer function for calculating the delayed recharge of groundwater in areas lacking hydrogeological data. The results show that the thickness of the vadose zone is an important factor affecting the delayed recharge, and the number of linear reservoirs and storage ability parameters need to be adjusted for areas with thicker vadose zones.

Through numerical simulations and graph conceptualization, preferential and stagnant flow regions can be distinguished, and the channelization of flow can be quantified. By analyzing weighted paths and structural similarity, accurate flow paths can be predicted and the flow structure within the pore network can be explained.

Summary: In this study, CeO2/K-OMS-2 catalyst was synthesized for photocatalytic toluene oxidation, showing excellent activity and stability. It was found that the presence of K+ in the K-OMS-2 channels changed the Fermi levels, leading to the formation of heterojunctions and promoting charge transfer. Moreover, the interaction between oxygen species on the catalyst surface and photo-generated charges generated radicals, which catalyzed the oxidation reaction. It was also observed that the reaction process was influenced by the humidity to some extent.

Summary: This study compared the retention and transport of carboxymethyl cellulose (CMC) modified nZVI (CMC-nZVI) and sulfidated nZVI (CMC-S-nZVI) particles in saturated columns packed with quartz sand. The results showed that grain size reduction inhibited the transport of both CMC-nZVI and CMC-S-nZVI, while metal oxide coatings had minimal effect. CMC-S-nZVI exhibited higher breakthrough and mass recovery compared to CMC-nZVI under the same experimental conditions.

Summary: Effluent from wastewater treatment plants is a major source of nanoplastics in the environment. This study found that integrating granular limestone into rapid sand filter systems can greatly enhance nanoplastics removal from water. The higher removal efficiency of nanoplastics by limestone is attributed to its chemical composition, surface heterogeneity, and roughness.

Summary: This study critically reviews the effects of biochar (BC) on the mobilization, phytoextraction, phytostabilization, and bioremediation of potentially toxic elements (PTEs) in contaminated soils. The potential mechanisms of interaction between BC and PTEs in soils are discussed in detail. The review demonstrates the contradictory effects of BC on PTE mobilization and highlights the opportunities for using BC as a mobilizing agent to enhance phytoremediation of PTE-contaminated soils.

Summary: Biochar is a promising environmental remediation agent due to its adsorptive and catalytic properties. However, the environmental effects of persistent free radicals (PFRs) produced during biochar production are still not well understood. This review aims to provide an overview of the formation mechanisms and types of biochar PFRs, evaluate their environmental applications and potential risks, summarize their migration and transformation in the environment, and explore effective management strategies for biochar PFRs. Future research directions are also recommended.

Summary: In this study, a novel heterogonous catalyst FCBC was prepared through a one-step co-pyrolysis protocol, which demonstrated excellent efficiency in degrading organic pollutants by activating PDS. The catalyst showed structural defects, high surface area, and low electrical impedance, leading to the generation of reactive oxygen species. The cascade reactions involving sulfate radicals and hydroxyl radicals, as well as non-radical pathways, contributed to the degradation of Rhodamine B.

Summary: Lignin biochar was effectively modified using acid washing and ultrasound treatment to enhance its CO2 sorption capacity. The treatment improved the surface cleanliness and porosity of the biochar, resulting in increased specific surface areas and micropore volumes. The post-treated biochar exhibited high CO2 uptake due to its developed micropore structure, and adsorption analysis revealed multilayer physical adsorption as the main mechanism. The acid washing and ultrasound treatment technique showed great potential for CO2 capture with its high adsorption capacity, excellent reusability, and selectivity.

Summary: In this study, two different morphologies of Ti3C2Tx MXene were prepared and their structural differences were explored. It was found that delaminated Ti3C2Tx had higher adsorption capacity for Pb(II), while multilayer Ti3C2Tx had higher adsorption capacity for Cu(II). The removal mechanisms for Pb(II) and Cu(II) were also determined. Both MXene morphologies showed excellent adsorption capacity for heavy metal pollutants and good reusability.

Summary: Biochar, attapulgite, and diatomite were co-ball milled to prepare mineral-biochar composites for wastewater treatment. The composites showed better adsorption capacity for methylene blue compared to ball milled biochar and mineral alone. The 10% composites of attapulgite-biochar and diatomite-biochar had the highest adsorption capacities, which were 2.7 and 2.3 times that of ball milled biochar, respectively. The improved adsorption is attributed to the oxygen-containing functional groups and cation exchange capacity of the composites.
