Summary: This study compares the influence of different electrodeposition methods on the electrochemical properties of films made from pyrogallol or pyrocatechol on amorphous carbon electrodes. It was found that chronoamperometry is more efficient for pyrocatechol-based films, while fewer cyclic voltammetry cycles are needed for pyrogallol-based films to become impermeable to hexacyanoferrate anions.

Summary: The kinetic properties of Ni(II) in FLiNaK molten salt were investigated using various electrochemical techniques. The reduction of Ni(II) to Ni(s) was found to be a single step, two-electron transfer process. Diffusivity values were calculated using different equations and methodologies, with a range of 3.27 x 10(-7)-3.04 x 10(-6) cm(2) s(-1) and an activation energy of 62-104 kJ mol(-1). The variations in the estimated kinetic properties may be attributed to the assumptions made in the theoretical models regarding reversibility and unit activity during Ni metal deposition.

Summary: The electroactivity of Chlorophytum rhizospheric soil was demonstrated using imposed potential chronoamperometry and cyclic voltammetry, showing different current densities at various electrode polarizations. The potential + 0.155 V/SCE appeared to stimulate electrogenic bacteria activity, leading to the formation of electroactive biofilms by different bacterial strains in the rhizosphere. The soil composition of Chlorophytum rhizosphere, particularly the presence of Firmicutes and Proteobacteria, influenced the electroactivity and development of electroactive biofilms.

Summary: The adsorption of hexylamine at the solution-gold interface in 1 M HClO4 in the presence of 0.1 M Fe2+ and 0.1 Fe3+ was studied. The main kinetic characteristics of the oxidation-reduction reaction of iron ions were determined. It was shown that the physical adsorption of hexylamine on gold can be described by the Dhar-Flory-Huggins isotherm. The adsorption at these interfaces is mainly due to the hydrophobic effect of the interaction of hexylamine and water molecules.
