Summary: Phosphorus pollution can cause both aquatic eutrophication and global phosphorus scarcity. Fe-based layered double hydroxides (LDHs) have been extensively studied for their high phosphorus adsorption and recovery. The composition of Fe-based LDHs is crucial in determining their adsorption performance. In this study, Zn/Fe LDH exhibited a much higher adsorption capacity than Mg/Fe LDH, and calcination significantly increased the adsorption capacity of Mg/Fe LDH. The phosphorus removal efficiency of Fe-based LDHs was high under acidic conditions but decreased with increasing pH, with Zn/Fe LDH showing weaker pH inhibition.

Summary: In this study, a theoretical assessment of o-nitrophenol adsorption on layered double hydroxides containing different metallic species (Ca-Al, Ni-Al and Zn-Al) was conducted. It was found that the adsorption capacities of these layered double hydroxides for o-nitrophenol were similar, indicating that they played a comparable role in adsorbing o-nitrophenol molecules from aqueous solution. The calculated adsorption energies and thermodynamic functions confirmed an exothermic adsorption process.

Summary: A novel composite material SL-1.0 was synthesized in this study, which demonstrated great potential for simultaneous removal of benzotriazole and lead ion from wastewaters due to its facile synthesis and excellent adsorption capacity. The adsorption mechanism involved electrostatic attraction and chemical bonding with surface functional groups, with hydrogen bonding and 7C-7C interaction mainly contributing to benzotriazole adsorption and complexation with surface function groups dominating lead ion adsorption.

Summary: Ni2+/Fe3+ LDH, (Ni-Fe-CO3 LDH) with Ni/Fe molar ratio 3.0 was synthesized by co -precipitation for the remediation of chromium (VI) and Alizarine Red-S (ARS-dye). The effects of hydrogen ion concentration, shaking time, ARS-dye and/or Cr(VI) concentration, and adsorbents mass on the process were studied. The results showed that Ni-Fe-CO3 LDH fitted well with the pseudo-second-order model, and Langmuir isotherm had a better adsorption effect on ARS-dye and Cr(VI).

Summary: In this study, a novel composite material LDH@CNT was prepared using an in-situ method, which had a favorable adsorbent structure due to the mutual support of LDHs and CNTs. The adsorption kinetics of LDHs, CNTs, and LDH@CNT composites for tetracycline were well described by intraparticle diffusion and pseudo-second-order models, indicating that the adsorption site played a major role. The Generalized Langmuir model was found to better describe the adsorption process than the Langmuir model, suggesting multiple interactions between tetracycline and the composite material. Site energy distribution theory combined with molecular simulation explained the adsorption mechanisms, and the removal of tetracycline by LDHs, CNTs, and LDH@CNT composites was calculated. The results showed that LDH@CNT composites had lower average site energies compared to LDHs and CNTs, but had more exposed adsorption active sites, leading to improved removal efficiency of tetracycline.

Summary: A series of novel layered double hydroxides (Mg-Fe-Ti-LDHs) containing Mg2+, Fe3+ and Ti4+ were prepared and their adsorption performance on vanadate in aqueous solution was investigated. The results showed that the introduction of Ti4+ into the LDHs materials increased the vanadate adsorption efficiency. The adsorption capacity was also influenced by the anion intercalated layers, with Cl- intercalation showing higher removal compared to CO32-. The pH of the solution and coexisting ions also had significant effects on vanadate adsorption.

Summary: This study proposes Pickering emulsions based on wax and halloysite clay nanotubes for coating silk sutures to increase their loading capacity towards eosin. The presence of halloysite/wax microspheres on the surface of silk sutures has also been explored for controlled release of hydrophobic drugs. The influence of the coating on the thermal and mechanical properties of the sutures has been studied using various techniques. In conclusion, the wax/halloysite Pickering emulsions can successfully generate hydrophobic microdomains on the surface of silk sutures, leading to enhanced flexibility and improved loading capacity towards eosin.

Summary: Operational problems in the oil industry caused by the precipitation of paraffins can be prevented by using polymeric additives. This article evaluates the use of polymeric nanocomposites as pour point reducers in different types of crude oil and finds that they are more efficient than pure poly(ethylene-covinyl acetate) (EVA) in reducing the pour point. The nanocomposites also modify the wax crystals and reduce the viscosity of the oil samples.

The impact of fluid salinity and void space on the swelling behavior of barrier bentonites was examined through experiments. The findings suggest that clay swelling is suppressed at higher salinities, which affects the void-filling process.

Summary: Rutile nano-TiO2 was loaded onto the surface of sericite to prepare sericite-rutile composite particles, which were then modified with HDTMS and sprayed onto the substrates to form sericite-rutile/HDTMS composite coatings with UV shielding and superhydrophobic self-cleaning properties. The coating exhibited good UV shielding rate and remained superhydrophobic after UV irradiation. The hierarchical structure of the sericite-rutile composite and the low surface energy of HDTMS contributed to the superhydrophobicity and UV shielding effect of the coating.

Summary: Chitosan-Pd0 nano particles encapsulated in Al, Co-pillared montmorillonite nanocomposites were successfully synthesized using a facile one-pot heat treatment method. The Al, Co pillaring effectively expanded the surface area and generated numerous mesopores in the interlayer space of the MMt. The resultant nanocomposite exhibited similar high comprehensive catalytic performances as the one prepared by the regular divided-multistep method. The encapsulation of CS chains and doping of Co in the Al pillaring also contributed to the improved catalytic performance.

Summary: Environmental conditions significantly influence clay minerals, and studying clay sediments in tropical lakes can provide valuable insights into past environmental conditions. In this study, multiproxy records from sediment cores of three crater lakes in central Mexico were analyzed. The results showed that disordered kaolinite, formed through hydrolysis and hydrothermal alteration, was the predominant mineral in the sediments. The abundance of kaolinite varied in relation to organic carbon and organic matter-related elements, and showed opposite trends with lithogenic elements. Geochemical data suggested that the increase in kaolinite abundance is linked to the formation of organo-mineral aggregates and lake level changes in closed basins.

Summary: The interaction between talc and the depressor CMC was investigated through molecular dynamics simulation and density functional theory calculation. It was found that CMC showed stronger adsorption on the edge plane of talc due to enhanced interactions with polar groups and water molecules. The study also revealed specific interactions between H atoms in CMC and O atoms in the edge plane, as well as between O atoms in CMC and Si, Mg atoms in the edge plane. Hydration shells on the basal and edge planes of talc were examined to explain the phenomenon.
