TL;DR: In this article, a home-made electrochemical cell has been used to better follow the evolution of the morphology of the polymer film growth, particularly during the early stages of the polybithiophene film growth.

TL;DR: In this paper, anodic stripping voltammetry of cadmium and lead in pure water, of conductivity as low as 0.6 μS, was studied at a mercury microelectrode obtained by ex situ deposition of mercury on a 10-μm radius platinum disc electrode.

TL;DR: In this paper, the electrocatalytic hydrogenation of benzene, aniline, and nitrobenzene at a Raney nickel powder cathode was investigated at a single phase electrolyte consisting of t-butanol, water, and a hydrotropic salt, either sodium or tetraethylammoniump-toluenesulphonate (TEATS).
Abstract: The electrocatalytic hydrogenation of benzene, aniline, and nitrobenzene was investigated at a Raney nickel powder cathode. The single phase electrolyte consisted of t-butanol, water, and a hydrotropic salt, either sodium or tetraethylammoniump-toluenesulphonate (TEATS). The hydrogenation of benzene was achieved only in the latter case; the only product detected was cyclohexane. The highest current efficiency (73%) was obtained at 50° C, 1.0m benzene, 2.5m TEATS, and at an apparent current density of 4.0 mA cm−2. Aniline was electrocatalytically hydrogenated to cyclohexylamine only in the presence of a quaternary ammonium ion supporting electrolyte (containing either Br− orp-toluenesulphonate anions), with product current efficiencies of ∼40%. When nitrobenzene was hydrogenated with a sodiump-toluenesulphonate supporting electrolyte, only nitro group reduction was observed. When the supporting electrolyte was TEATS, both nitro group reduction and aromatic ring hydrogenation occurred.

TL;DR: The electrochemical oxidation of antihypertensive drug carveilol has been studied in pH range 2.0-11.0 at a glassy carbon electrode by cyclic and differential pulse voltammetry and the developed method was used for the determination of carvedilol in tablet dosage form.
Abstract: The electrochemical oxidation of antihypertensive drug carvedilol has been studied in pH range 2.0–11.0 at a glassy carbon electrode by cyclic and differential pulse voltammetry. Two oxidation processes were produced in different supporting electrolyte media. Both oxidation processes were irreversible and diffusion-controlled. The first oxidation process was chosen for the analysis of carvedilol. A very resolved voltammetric peak was obtained in Britton–Robinson buffer at pH 8.0 using differential pulse mode. The linear response was obtained in the range of 0.25–10.00 μg ml –1 . The limit of detection was found to be 0.10 μg ml –1 . The developed method was used for the determination of carvedilol in tablet dosage form.

TL;DR: Magnetic graphene oxide (GO@Fe3O4) modified with benzothiazole-2-carboxaldehyde (2-CBT) was used for the first time for the simultaneous determination of trace amounts of lead and cadmium in the aqueous solution by means of SWASV as mentioned in this paper.
