In vitro electrical impedance spectroscopy of human dentine: The effect of restorative materials
(Wiley-liss, Div John Wiley & Sons Inc, 2008-04)
The influence of different restorative materials on in vitro dielectric properties of sound dentine was investigated. The studied samples were three-layer materials consisting of successive disks of dentine and silver ...
Complex numbers-partial least-squares applied to the treatment of electrochemical impedance spectroscopy data
(Elsevier Science, 2019-11)
This work investigated the application of partial least-squares regression of complex numbers on multivariate data obtained by electrochemical impedance spectroscopy (EIS). The use of complex numbers–PLS was evaluated in ...

(Elsevier Science, 2006-03)
The electrode reaction of the perovskite phases Sr1-xLaxCo0.8Fe0.2O 3-δ (x = 0.1 and 0.6) on Ce0.9Gd0.1O1.95 has been investigated by impedance spectroscopy in the temperature range 600 ≤ T ≤ 800 °C. Thick porous electrodes ...
Development of an impedimetric immunosensor to determine microcystin-LR: New approaches in the use of the electrochemical impedance spectroscopy was used in determining to determine kinetic parameters of immunoreactions
(Pergamon-Elsevier Science Ltd, 2020-09)
The development of new electrochemical immunosensors for the detection of environmental contaminants is of great interest due to their simplicity, high sensitivity, and extended analytical range. Because of the antibody ...
Carbon xerogels as electrochemical supercapacitors. Relation between impedance physicochemical parameters and electrochemical behaviour
(Elsevier, 2012-07)
The electrochemical behavior of carbon xerogels was studied with the aim of analyzing the performance of the materials used as electrochemical supercapacitors (SC) and to relate with physicochemical parameters. These ...
PtRu supported on mesoporous carbon as anode catalyst for direct methanol fuel cell (DMFC): Electrochemical impedance analysis of mass transport
(Elsevier, 2013-04)
The performance of membrane electrode assembly (MEA) prepared with PtRu nanoparticles supported on a mesoporous carbon as anode catalyst are presented and compared against PtRu synthesized over Vulcan carbon. Polarization ...
Two mechanisms of conduction in polycrystalline SnO2
(Elsevier Science Sa, 2009-02)
Impedance spectroscopy was carried out on SnO2 thick films exposed to different atmospheres. Oxygen desorption and adsorption during heating and cooling processes, respectively, onto the grain surface affects the resistance ...
Grain boundary and grain interior conduction in γ′-Bi2MoO6
(Elsevier Science, 2005-07)
Impedance spectroscopy of fine grained (<10 μm) γ′- Bi2MoO6 samples, in the frequency range of 0.1 Hz-250 kHz, relevant to sensor applications, up to 800°C, has been used to characterize grain boundary and grain interior ...
Disposable Electrochemical Sensor for Rapid Determination of Ethyl Xanthate in the Mining Industry
(Wiley VCH Verlag, 2018-11)
Xanthate is a widely used reagent in sulfide mineral flotation. A simple and reliable method is presented for the direct monitoring of xanthate in flotation baths and their effluents, as a tool for their reconditioning, ...
A weak mixed mobile ion effect in vanadium-tellurite oxide glass modified by silver and lithium cations
(Elsevier Science, 2010-11)
The effect of the partial replacement of lithium oxide by silver oxide in a glassy vanadium-molybdenum-tellurite oxides matrix is analyzed by means of impedance spectroscopy. We find that a weak mixed mobile ion effect ...
