This study focuses on developing a sustainable multifunctional SNAP (sodium alginate/nickel oxide/ammonium polyphosphate/polypyrrole) porous material, fabricated by incorporating sodium alginate (NaAlg) as the primary structural matrix, ammonium polyphosphate (APP) as a flame retardant, nickel oxide (NiO) for temperature sensing and enhanced flame retardancy, and polypyrrole (PPy) to improve electrical conductivity for fire warning functionality. The inclusion of APP, NiO, and PPy significantly improved the limiting oxygen index to 48.7 %, and a robust char layer during flame exposure provided effective thermal barrier and self-extinguishing properties. The porous material exhibited thermal conductivity of 0.076 W·m⁻¹·K⁻¹. The synergistic integration of NiO and PPy enhanced temperature sensing and electrical conductivity, enabling ultrafast (0.9 s) flame detection and a stable fire warning period of 227 s (under continuous exposure) with reversible warning characteristics. Post-crosslinking with Ca²⁺ ion improved mechanical strength (0.32 MPa) and maintained stability up to 48 h of immersion in deionized water.

The results of temperature sweep indicated that the binding temperatures of Dea-XG and XG with GSP are above the point of transition from disorder to order of the XG conformation, while Dep-XG is opposite.

Emerging research highlights the potential of dietary interventions, particularly dietary fiber (DF) and polyphenols, in modulating gut microbiota composition and function. DF serves as a fermentable substrate for beneficial gut bacteria, promoting the production of short-chain fatty acids (SCFAs). Polyphenols, a diverse group of bioactive compounds selectively modulate microbial populations and contribute to the production of bioactive metabolites with host health benefits. Importantly, the interplay between DF and polyphenols creates a synergistic effect within the gut microbiome, shaping microbial diversity, enhancing SCFAs production, and strengthening gut barrier function, which together support metabolic and immune homeostasis. This review systematically explores the synergistic effects of DF-polyphenol combinations on gut microbiota modulation, microbial metabolites, and their implications for overall health. The combined effects of DF and polyphenols hold promise for targeted nutritional strategies in preventing metabolic disorders and improving gut health. Moreover, the extent of these benefits is influenced by the structural characteristics of DF, the source and dosage of polyphenols, and individual gut microbiota composition.
