Summary: The effect of ball-to-powder weight ratio on the properties of palygorskite was systematically studied, showing that a ratio of 1:2 can effectively separate quartz from palygorskite and increase specific surface area and micropore volume. The purified palygorskite was used as a template to prepare a palygorskite/Fe3O4 nanocomposite, which successfully prevented aggregation of Fe3O4 magnetic particles and increased the specific surface area and absorption frequency.

Summary: The study successfully achieved the disaggregation of palygorskite crystal bundles and the stable dispersion of palygorskite rod crystals through scale-up ultrasonication and thermosonication. The results showed that highly dispersed individual palygorskite nanorods could be continuously produced by sonicating palygorskite dispersion at 30 degrees C for 8-12 min, retaining the original nanorod crystal morphology and layered-chain microstructure. The disaggregated palygorskite nanorods were then used to stabilize carvacrol and fabricate antibacterial Pickering emulsion with outstanding storage stability and excellent antibacterial activity.

Summary: This study reports a strategy to efficiently manipulate carbon nanotube (CNT) networks by forming double networks with branched polyethylenimine (PEI). The double network had high viscoelasticity and ductility, enabling efficient film stretching or creeping for CNT alignment, significantly improving the mechanical strength of CNT films. The viscous drag from the polymer network enhanced the movability of CNTs in reconstructing new networks, resulting in the film's repairability. This double-networking strategy provides a new way to manipulate CNT assemblies for high-performance applications.

Summary: The rapid development of antibiotic resistance is a major threat to public health. Nanomaterials, particularly ZnO nanocrystal clusters, have shown excellent bactericidal ability. The clusters, formed through a green structure-tuning synthesis process, exhibited superior performance in killing Escherichia coli and Staphylococcus aureus. The antibacterial action is attributed to increased contact with bacteria, the release of small ZnO nanoparticles, and the generation of reactive oxygen species, which damage the bacterial cell membrane. In addition, the attachment of phenolic compounds from olive leaf extract enhances the antibacterial activity of ZnO clusters. This study presents a feasible and clean strategy for improving the structure-bioactivity relationship of ZnO and highlights the potential of ZnO clusters in antibacterial applications due to their excellent performance and green fabrication method.

Summary: In recent years, porous adsorption materials have received extensive attention in environmental remediation. However, green preparation and effective post-treatment are still the main challenges in practical applications. In this study, a novel porous adsorbent was successfully fabricated from aqueous foams templates stabilized by natural plant Sapindus mukorossi (S. mukorossi) and nano-clay attapulgite (APT) via a thermally-initiated polymerization. The as-prepared porous adsorbent exhibited abundant interconnected pore structures and demonstrated excellent adsorption properties for chlortetracycline hydrochloride (CTC) and tetracycline hydrochloride (TC), with a maximum adsorption capacity of 620 mg/g and 538 mg/g, respectively. After adsorption, the waste porous adsorbent was converted into carbon/APT material through anaerobic calcination. At a carbonization temperature of 400 degrees C, carbon/APT with large amounts of negative charges and oxygen-containing functional groups exhibited a good adsorption capacity for Cd2+ and showed potential as a soil remediation agent.

Summary: Super-wetting membranes with catalytic performance were fabricated using Fe3O4-loaded attapulgite (FATP) nanofibers. These membranes possess hydrophilicity and micro-nano roughness, which resist oil fouling and act as a catalyst for the Fenton-like reaction. During oil-in-water filtration, more than 99.5% of oil droplets can be rejected, and membrane permeance remains at 62% of its initial value. After hydraulic cleaning, the permeance recovers to 85%, and the remaining 10.9% can be restored through the Fenton-like reaction. This study provides insights into the catalytic mechanism of membranes after oil fouling.

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: 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.
