The risks associated with wound infections are significant, making a snug-fitting hydrogel dressing an optimal choice for wound management. For it, we employed the self-cross-linking method of oxidized sodium alginate (SCSA), incorporating clarithromycin (Cla) and basic fibroblast growth factor (bFGF) to formulate a rapidly forming, bacteriostatic, and wound-healing hydrogel (SCSA@C/b). Bacteriostatic and cytocompatibility assays demonstrated that SCSA@C/b exhibits exceptional antibacterial activity alongside strong biocompatibility. A fractional infected wound model showed that SCSA@C/b accelerated healing of infected wounds by approximately three days compared to the healing time of the control group, with nearly complete wound recovery. H&E staining and SEM analysis of the healed wound sections revealed significant pro-healing effects. Thus, SCSA@C/b is a promising medicinal hydrogel for encouraging wound healing in contaminated areas.

This study introduced a hydrogel dressing, termed SODex-gel, which was constructed by establishing Schiff base and hydrogen bonds with the precursors of oxidized dextran (ODex) and succinic dihydrazide (SD)-modified sodium alginate (SD--SA). Through comprehensive and studies, the adhesive properties, self-healing capabilities, hemostatic potential, and wound healing efficacy of the SODex-gel dressing were meticulously evaluated. The H NMR, FTIR, and TGA analyses confirmed the fabrication of the SODex-gel dressing and its constituent elements.

In the field of solar steam generation, hydrogels with interfacial evaporation configurations stand as a promising candidate for solar evaporators. Hydrogel-based photothermal materials provide excellent hydration channels for supplying water to an evaporative layer due to their porous structure and hydrophilic nature. This work proposed a facile and in-situ fabrication of sodium alginate hydrogel incorporated with cellulose nanocrystals and polypyrrole as an effective photothermal material.

Flexible hybrid minerals, primarily composed of inorganic ionic crystal nanolines and a small amount of organic molecules, have significant potential for the development of sustainable structural materials. However, the weak interactions and insufficient crosslinking among the inorganic nanolines limit the mechanical enhancement and application of these hybrid minerals in high-strength structural materials. Inspired by tough biominerals and modern reinforced concrete structures, this study proposes introducing an aramid nanofiber (ANF) network as a flexible framework during the polymerization of calcium phosphate oligomers (CPO), crosslinked by polyvinyl alcohol (PVA) and sodium alginate (SA).
