Summary: Electrokinetic (EK) technology has been proposed as a promising method for removing heavy metals from contaminated unsaturated soils. A novel method was presented for estimating the electro-osmotic permeability of unsaturated porous media, which considers the difference in mass-transfer efficiency between cases with and without electro-osmotic flow. The feasibility of the method was validated through experiments with hexavalent Cr as the target contaminant.

Summary: Geological carbon sequestration in deep saline aquifers is crucial for reducing greenhouse gas emissions, but the solubility of CO2 in water is affected by various factors. Research indicates that the solubility of CO2 is lower in calcite pores and decreases as the pores narrow. Simulation results also suggest that the presence of ions influences the solubility of CO2 in confined water.

Summary: This study examines the effect of angstrom-scale graphene nanopores on water evaporation from salt solutions. Cation-pi interactions between ions and the nanoporous graphene surface significantly affect ion concentrations in the nanopore vicinity, resulting in different evaporation fluxes from different salt solutions. The highest evaporation flux was observed for 0.6 M NaCl solution, similar to seawater composition. Functionalized nanopores reduce surface tension at the liquid-vapor interface, lowering the free energy barrier for water evaporation without affecting ion hydration dynamics. These findings can contribute to the development of low thermal energy input technologies for desalination and separation processes.

Summary: Anthocyanin, a water-soluble pigment found in plants, is associated with abiotic stress tolerance, including salt stress. Using two salt-tolerant rice genotypes with different leaf anthocyanin content, the study revealed that the green-leaved variety PK showed better Na+ exclusion mechanism, while the purple-leaved variety ND 019 focused more on osmotic adjustment under salt stress. Interestingly, anthocyanin did not play a vital role in protecting the purple-leaved rice, ND 019, from salt stress during the seedling stage.

Summary: Salt ions play a critical role in regulating interactions between charged particles. The effective interactions between oppositely charged particles can be attractive for low salt valence and become repulsive for high salt valence. The non-monotonic salt-valence dependence of the effective repulsions is influenced by the interplay between ion translational entropy and electrostatic energy.

Summary: We used nuclear magnetic resonance to investigate the dynamics of LiCl-7H(2)O and LiCl-7D(2)O solutions in silica nanopores. We found that the solution dynamics are slower in functionalized pores compared to pristine pores. Bimodal dynamics of water and lithium ions may be observed when the exchange between different confinement regions is slow at reduced temperatures. We suggested that steric hindrance and electrostatic interactions in functionalized pores interfere with the formation of a defined electric double layer, resulting in overall slower dynamics.

Summary: The stability of dispersions containing charged particles can be regulated by salt, and charge reversal and added salt can increase colloidal stability. Through simulations and calculations, it has been found that the experimentally observed nonmonotonic dependence of colloidal stability on salt concentration can be explained, with all non-DLVO aspects attributed to ion-ion correlations.

Summary: Understanding the interaction of ions with charged silica nanoparticles is crucial for producing gels and determining long term stability. In mixtures, monovalent ions generally follow the Hofmeister series, but divalent ions do not. At pH < 9, mixtures of divalent and monovalent salts follow the normal Hofmeister series, while at pH > 9 a reversal is observed.

Summary: The structural transformations of charged spherical surfactant micelles of potassium oleate upon solubilization of water-insoluble polymer poly(4-vinylpyridine) were studied. The solubilization of the polymer resulted in the formation of complexes with necklace structure, where the polymer penetrated into the hydrophobic core of the micelles and occupied about 60% of their volume. This led to a decrease in the number of surfactant ions in the micelles. The bound charged micelles imparted water solubility to the polymer-surfactant system, behaving like a polymer coil in a good solvent.

Summary: Phospholipids are essential biomolecules with a headgroup and two acyl tails, where the asymmetric nature of the acyl tails plays a crucial role in defining the biophysical properties of lipid bilayers. Studies have shown that structurally asymmetric glycerophospholipids in yeast membranes may have distinctive biophysical properties, and they can maintain membrane lipid order even at various temperatures. Additionally, asymmetric lipids can substitute for unsaturated symmetric lipids in the phase behavior of ternary lipid bilayers, allowing cells to maintain membrane fluidity in oxygen-lacking environments.

Summary: The pharmacodynamic profile and in vivo synergy of antimicrobial peptides (AMPs) play important roles in limiting resistance evolution and ensuring their conservation. Research has shown that the antibacterial potency of temporin L can be synergistically increased when combined with temporins B and A. This synergistic effect may be due to altered interaction with the bacterial plasma membrane. Furthermore, the addition of buforin II can further enhance the cooperativity between temporins B and L. Understanding the mechanism of synergy between AMPs from the same organism can lead to the development of antibiotic combinations with advantageous pharmacodynamic properties.

Summary: All-atom molecular dynamics simulations were used to investigate the structural properties of micelles formed by the non-ionic surfactant Triton X-114. The solubilisation of two nonsteroidal anti-inflammatory drugs (NSAIDs), ibuprofen and indomethacin, was also studied to understand its effect on the micelle structure. The results showed that solubilising drug molecules caused the micelle shape to become elongated and the drug molecules took orientations within the core of the micelle to remain hydrated. The aggregation of indomethacin led to destabilisation of the micelle, while the ibuprofen-loaded micelle remained stable.

Summary: This study presents a structural model of the PorV:RgpB-CTD complex from P. gingivalis, providing insight into the recognition mechanism of cargo proteins by the type IX secretion system (T9SS). The study shows that the conserved motifs in the C-terminal signal domain (CTD) are the primary binding sites for T9SS recognition. The interactions of PorV with extracellular surface loops play a crucial role in binding the CTD and securing the RgpB-CTD in place. This research not only advances our understanding of cargo recognition by PorV but also has important implications for other aspects of type-IX dependent secretion.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions.
