Summary: The fabrication of impervious adherent polymeric coatings over metallic surfaces is an effective strategy for metal protection from corrosion. Poly-2-amino-1,3,4-thiadiazole (p-ATD) films were electrodeposited on copper surfaces using cyclic voltammetry to prevent corrosion in a corrosive medium. The addition of metal oxides, particularly nano TiO2, significantly improved corrosion resistance compared to other composites. The combination of p-ATD and metal oxides suppressed the hydrogen evolution reaction, leading to enhanced corrosion protection.

Summary: Electropolymerization of 5-amino-2-naphthalenesulfonic acid on carbon cloth is used to construct conductive coatings for flexible supercapacitor electrodes. The resulting poly(5-amino-2-naphthalenesulfonic acid) coated carbon cloth electrodes exhibit high charge storage performance. The PANS/CC-40 electrode shows a specific capacity of 85.5 mAh g-1 in 1 M H2SO4, and 44.8 mAh g-1 in 1 M ZnSO4 and 38.5 mAh g-1 in 1 M (NH4)2SO4, both at 1 A g-1. Kinetic analyses reveal that the PANS/CC-40 electrode operates through surface-controlled processes, with over 80% of stored charge contributed by these processes. The electrode also shows evidence of cation (de)intercalation accompanying the redox of amine/imine groups. A symmetric supercapacitor assembled with PANS/CC-40 electrodes and PVA/H2SO4 gel electrolyte demonstrates good energy and power densities, with capacity retention of 88% after 10,000 cycles at 5 A g-1.

Summary: This study focused on the energetic-structural correlations of compounds with a pentagonal heterocyclic ring and different substituents, contributing to the assessment of their thermodynamic stability and understanding of the thiol-thione tautomeric equilibrium. Experimental and computational thermochemical studies of three mercaptothiadiazoles were conducted, revealing that methyl-substituted thiadiazole is more stable in both gaseous and crystalline phases. Quantum chemical calculations confirmed the thione form as the predominant tautomer for mercaptothiadiazoles. Activation energies of the tautomeric equilibrium were calculated, showing that thiol-thione hydrogen transfers are unfavorable reactions in gas phase and with polar solvents present.

Summary: The galvanic reaction between graphene quantum dot (GQD)-stabilized silver nanoparticles (AgNP)-modified glassy carbon (GC) surface and Hg(II) leads to the complete dissolution of AgNPs within 15 minutes and the subsequent growth of Hg(0) as a flower on the GQD surface. This unique anti-amalgamation reaction is caused by direct deposition of Hg(0) by available oxygen functional groups and strong adsorption on the GQD graphene surface, followed by subsequent growth of Hg(0) as a flower due to the galvanic reaction between AgNPs and Hg(II).
