Summary: The use of mineral clays as alternative adsorbent has been explored due to their physicochemical characteristics and low cost. In this study, expanded vermiculite and sodium-modified vermiculite were evaluated for their adsorption capacity and ion exchange of Cd2+ ions. The sodification process successfully increased the ion exchange capacity of the modified clay, resulting in higher adsorptive capacity and faster kinetics for Cd2+ removal. Despite the decrease in surface area after sodification, the modified adsorbent showed a significant increase in adsorptive capacity.

Summary: Density functional theory calculations were used to study the formation of silanol groups on the outer surface of halloysite nanotubes through reactions with water in alkaline environments. The results demonstrate the highly exothermic nature of the formation of various silanol group configurations and the extraction of orthosilicic acid in the presence of hydroxide ions. Experimental analyses including thermogravimetric analysis, FT-IR, XRD, and X-ray fluorescence spectrometry confirm the increased adsorption of water on the outer surface and the corresponding increase in the number of silanol groups.

Summary: This work aimed to evaluate the influence of substituting conventional fine aggregate with LECA on the physical and mechanical properties of lightweight cement-based composites for 3D printing. The experimental results showed that replacing sand with LECA improved the thermal insulation performance of the composites without compromising their mechanical strength and porosity. Additionally, a mathematical equation that solely depends on the substitution content was derived to model the thermal behavior of the composites.

Summary: The interaction between amino acids and clay minerals has been studied, and the carboxyl group is found to play a crucial role in this process. Strong hydrogen bonds are formed between the H-atom of the carboxyl group and the O-atom of the hydroxyl surface. Additional hydrogen bonds can also be formed between the N-atom of the amino group and the surface -OH groups. The adsorption energy is higher on the hydroxyl surface compared to the siloxane surface.

Summary: A new strategy for enhancing enantioselectivity of cyclodextrins using gold nanoparticles and different CDs was reported. Limiting the degrees of freedom of physisorbed antipodes on a non-chiral surface can lead to amplification of conformational differences with native CDs. This strategy may offer an alternative approach for chiral probing of analytes by interfacial supramolecular electrochemistry.

Summary: This study combines atomistic molecular dynamics (MD) simulations and fluorescence spectroscopy to characterize the interaction between rhodamines 123 and B (Rh123 and RhB, respectively) and POPC bilayers. The study provides detailed insights on the similarities and differences in the behavior of bilayer-inserted Rh123 and RhB, related to the structure of the probes. The higher affinity of RhB for the membranes increases the local concentration and explains its higher apparent affinity for P-glycoprotein reconstituted in model membranes.

Summary: This study systematically investigates the pre-aggregation behavior of asphaltene in the absence and presence of ionic liquids (ILs) using molecular dynamics simulations. The effects of cation chain length and anion dimension on asphaltene aggregation are studied. The results show that ILs have a dispersing effect on asphaltene, and this effect is influenced by the alkyl side chain length of the cation and the radius of the anion. The findings are supported by DFT calculations. The study also demonstrates that CO2 acts as a precipitating agent, but does not affect the relative performance of the ILs.

Summary: The organocatalyst cinchonidine-squaramide was immobilized within three different deep eutectic solvents (DESs) and evaluated in an asymmetric Michael addition reaction. The results showed excellent yields (up to 99%) and enantioselectivities (up to 98%) using only 1 mol% of organocatalyst. The high recyclability of this system was demonstrated with 9 cycles using DES (betaine:D-sorbitol:water), and 5 cycles were achieved with only 0.5 mol% of organocatalyst, obtaining products with high yields (up to 95%) and excellent enantioselectivities (up to 94%).

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
