TL;DR: The proposed method was successfully applied in the simultaneous determination of paracetamol and caffeine in several pharmaceutical formulations (tablets), with results similar to those obtained using a high-performance liquid chromatography method (at 95% confidence level).

TL;DR: In this article, a non-linear fitting procedure was employed in order to analyze polarization curves obtained at several temperatures (25 −75 °C) and the results revealed that the traditionally accepted model described by a Volmer-Tafel route fails to fit the obtained experimental data.

TL;DR: In this article, the authors present studies involving metallic ions and the herbicide glyphosate, in terms of their synthesis, identification, stability and structural properties, based on data from the current literature.

TL;DR: The development of an electrophoresis microchip fabricated by a direct‐printing process, based on lamination of printed polyester films with end‐channel amperometric detection, and the performance of this device was evaluated by am perometric detection of iodide and ascorbate.

TL;DR: In this paper, the application of disk shaped gold ultramicroelectrode for nitrite determination with and without addition of supporting electrolyte was studied using the differential pulse voltammetric method.
