Summary: This paper aims to construct a novel antibacterial mesoporous silica (SBA-15) material containing chlorhexidine gluconate (CG), and to investigate its characterization, release, antibacterial activity, and toxicity. The SBA-15/CG antibacterial agents prepared with different drug concentrations showed sustained-release properties and excellent antibacterial effects against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Moreover, different doses of SBA-15/CG did not cause pathological changes in the organs of rats. Therefore, SBA-15/CG is non-toxic and has promising and broad clinical applications for bacterial infections.

Summary: This study separated carbon dots (CDs) derived from chlorhexidine gluconate into three groups with different particle sizes and found that the antibacterial activity increases as the size of the CDs decreases. This phenomenon may stem from the differences in cellular uptake and distribution of CDs in the plasma membrane, as well as the restriction between the polar functional group and DNA molecule.

Summary: Most bioadhesives are ineffective on bleeding tissues and postoperative adhesion is a common issue. A three-layer biodegradable Janus tissue patch (J-TP) is developed to efficiently close bleeding wounds, promote clotting, and prevent tissue adhesion. The J-TP's adhesive hydrogel bottom layer forms strong adhesion to bleeding tissues through chemical bonding, while the middle layer improves tensile strength and the top layer prevents postoperative adhesion and inflammation. This J-TP shows promise in the clinical treatment of injured bleeding tissues with inhibited adhesion.

Summary: Multifunctional hydrogel dressings with chlorhexidine(CHX) loaded double network hydrogels showed cytocompatibility, antioxidant capability, and enhanced antibacterial activity. The hydrogels exhibited acid, glutathione(GSH), and trypsin triple-responsive release behaviors, accelerating CHX release under wound microenvironments. The freeze-drying hydrogels could be ground into powders and sprinkled on irregular wounds to reform hydrogel in situ, which were more convenient for sterilization, formulation, and storage. The xerogel powder dressing significantly promoted collagen deposition and reduced inflammation in vivo, accelerating wound closure and regeneration.

Summary: In this study, a multifunctional decellularized scaffolds (DCS)-based vascular patch with improved mechanical properties and biocompatibility was designed. The surface of the patch was coated with ammonium phosphate zwitter-ion (APZI) and poly(vinyl alcohol) (PVA) hydrogel, followed by the decoration of a heparin (Hep)-loaded metal-organic framework (MOF) to inhibit blood coagulation and promote vascular endothelialization. The obtained artificial vascular patch showed suitable mechanical properties, good biocompatibility, and blood compatibility. It also demonstrated enhanced proliferation and adhesion of endothelial progenitor cells (EPCs). The results from imaging techniques confirmed the patency of the implanted artificial vascular patch.

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.

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.
