Enhanced hydrogen evolution activity of Ni[MoS2] hybrids in alkaline electrolyte
(Springer, 2020-05)
In this paper is presented a simple one-pot synthesis of a composite electrode with a non-noble metal for the catalysis of hydrogen evolution reaction in alkaline media. The Ni[MoS2] composite electrocatalyst has been ...
Low-temperature impedance spectroscopic analyses of ceramic electrodes based on Mo and Co co-doped SnO2
(University of Novi Sad, Faculty of Technology, 2019-11)
Low resistive electrodes based on Co and Mo co-doped SnO2 were prepared by the conventional solid-state reaction and sintered at 1250 °C for 2 h. Concentration of Co2O3 precursor was unchanged (1 mol%), while MoO3 was ...
Electrochemical impedance spectroscopy study of the LixMn2O4 interface with natural brine
(Elsevier Science Sa, 2018-06)
The LiMn2O4-Polypyrrole electrochemical cell has been shown to extract LiCl from natural brine at low voltage with high selectivity, low energy consumption (5?10 Wh·mol− 1) and good stability. The intercalation/de-intercalation ...
Resistivity humidity sensors based on hydrogenated amorphous carbon films
(IOP Publishing, 2019-02)
We have studied the humidity dependence of the electrical properties in hydrogenated amorphous carbon (a-C:H) films. The films were prepared in two stages combining the techniques of physical deposition in vapor phase ...
Rate limiting steps of the porous La0.6Sr0.4Co0.8Fe0.2O3-δ electrode material
(Elsevier Science, 2009-11)
The electrode reaction of porous La0.6Sr0.4Co0.8Fe0.2O3-δ films deposited onto Ce0.9Gd0.1O1.95 (CGO) was investigated by impedance spectroscopy within the temperature and oxygen partial pressure (pO2) ranges of 500 ≤ T ≤ ...
Application of impedance spectroscopy to evaluate the effect of different setting accelerators on the developed microstructures of calcium phosphate cements
(Springer, 2009-12)
The main goal of the present study was to evaluate the effect of different setting accelerator agents on the developed microstructures of calcium phosphate cements (CPCs) by employing the impedance spectroscopy (IS) ...
Grain-size/(t″ or c)-phase relationship in dense ZrO2 ceramics
(Elsevier, 2016-07)
Zirconia-based materials are widely investigated and used as electrolytes in solid-oxide fuel cells, oxygen sensors and electrochemical devices. These materials present polymorphism, which has a critical effect on their ...
Application of a nickel hydroxide gold nanoparticles screen-printed electrode for impedimetric sensing of glucose in artificial saliva
(Elsevier Science SA, 2019-01)
In this study, a non-enzymatic glucose sensor (NEGs) based on the electrochemical deposition of nickel nanoparticles on screen-printed electrodes modified with gold nanoparticles, Ni(OH) 2 /AuNp/SPE, is obtained. SEM and ...
Immunosensor based on porous gold and reduced graphene platform for the determination of EE2 by electrochemical impedance spectroscopy
(Elsevier Science SA, 2021-09)
In this work, we report an electrochemical immunosensor to detect ethinylestradiol in water samples, using electrochemical impedance spectroscopy (EIS) as a detection technique. For the development of this immunosensor, ...
One step synthesis of high efficiency nickel/mesoporous TiO2 hybrid catalyst for hydrogen evolution reaction
(Elsevier B.V., 2019-02)
Nickel-TiO2 hybrid catalysts are synthesized by electrodeposition and their catalytic activity with respect to the hydrogen evolution reaction is analyzed. Two types of titanium oxide particles, which are commercial particles ...
