Graphycal Abstract: The physicochemical properties, phenolic composition, and antiradical activity of eight Moldovan dry red wines have been investigated to identify the key determinants of their radical scavenging capacity. Total phenolic content varied between 1.40 and 2.27 g GAE/L, with the highest values recorded in Gamay (Beaujolais), Codrinschii, and Saperavi wines. Gamay (Beaujolais) exhibited the highest anthocyanin content (1.256 g M3GE/L) and antiradical activity (1.94 g AAE/L), while Codrinschii wine showed the greatest proanthocyanidin content (0.36 g CE/L). The antiradical activity correlated most strongly with the total phenolic content (R²= 0.9854), anthocyanins (R²= 0.5739), proanthocyanidin’s content (R²= 0.4717) and free SO₂ (R² = 0.4216).

 

Graphycal Abstract: Novel imidazole-functionalized pyridinium-fused selenadiazolium salts were synthesized. X-ray structures display T-shaped selenium centers with Se···Cl/O chalcogen bonding interactions. The monocationic salt assembles into a 1D supramolecular polymer via [Se···Cl] dimerization and Se···N interactions.

 

Graphycal Abstract: Anti-corrosive additives reduce zinc corrosion in alkaline electrolytes, enhancing battery lifespan. Additives optimise electrode kinetics, increasing battery efficiency and overall performance. Citric acid with zinc acetate shows promising anti-corrosive properties. Optimization of additive formulations, scalability, and commercialisation are essential for widespread adoption.
