[EN] We report herein the design, manufacture and use of a "humid electronic nose" prototype based on voltammetric techniques. It consists of an array of four working electrodes (i.e., Au, Pt, Ir and Rh) housed inside a ...

A new definition for the electrochemical cell constant in conductivity measurements is presented in this paper. Electrochemical Impedance Spectroscopy and DC pulses measurements have been carried out in non-Faradaic ...

Ammonia (NH4 N) and orthophosphate (PO4 P) quantification in wastewater treatment plants is important due to their implication in the eutrophication process. A voltammetric electronic tongue as a tool for the prediction ...

In order to monitor the chloride penetration processes, a potentiometric embedded thick-film sensor was developed. This paper includes the results of research on the characterization of Cl− sensors made of Ag/AgCl resistive ...

[ES] Presentamos un sistema autónomo que monitoriza de forma remota el estado de las estructuras de hormigón armado. Este sistema realiza un seguimiento en tiempo real de la tasa de corrosión de las barras de refuerzo ...

A new electronic tongue to monitor the presence of glyphosate (a non-selective systemic herbicide) has been developed. It is based on pulse voltammetry and consists in an array of three working electrodes (Pt, Co and Cu) ...

Differences between the cell cross section and the electrodes area produce a heterogeneous distribution of the electric field that causes a non-linear relationship between electric resistance and distance for low values ...

The use of biomimetic measurement systems as electronic tongues and noses has considerably increased in the last years. This paper presents the design of a low-cost electronic tongue system that includes a software application ...

[EN] The new tendency to detect adulterated honey is the development of affordable analytical equipment that is in-line and manageable, enabling rapid on site screening. Therefore, the aim of this work was to apply an ...

Voltammetric techniques (open circuit potential, linear polarisation resistance and cyclic voltammetry) have been applied to study the corrosion of carbon steel in water. The study has been performed in aqueous solutions ...
