Thermal analysis and electrochemical study of Hg reactions on Pt-30% Ir alloy electrode
(Springer, 2006-11-01)
Thermogravimetry (TG), cyclic voltammetry (CV) and other analytical techniques were used to study the reactions of mercury with Pt-30% Ir alloy. The results allowed to suggest that an electrodeposited mercury film interacts ...
Electrochemical behaviour of copper electrode in concentrated sulfuric acid solutions
(Elsevier B.V., 1993-05-01)
The electrochemical behaviour of copper in 6.0 mol 1-1 sulfuric acid at 30°C, was studied by means of the potentiodynamic method. At low potential sweep rates, v < 200 m V s-1, the data reveal that the anodic process is ...
Direct preparation and characterization of copper pentacyanonitrosylferrate nanoparticles
(Hindawi Publishing Corporation, 2015-01-01)
The present work describes the preparation of nanoparticles of copper pentacyanonitrosyl complexes starting from the compound sodium nitroprusside. Copper pentacyanonitrosylferrate (NCuNP) nanoparticles were successfully ...
Electrochemical and spectroscopic studies of tungstencarbonyl complexes containing nitrogen and phosphorous ligands
(Soc Brasileira Quimica, 2000-07-01)
The present work deals with the synthesis, spectroscopic investigation and electrochemical behaviour of the compounds [W(CO)(4)(bipy)] (1), [W(CO)(3)(bipy)(dppm)] (2) and [W(CO)(3)(bipy)(dppf)] (3), bipy = 2,2'-bipyridine; ...
Silsesquioxane Modified with PAMAM Dendrimer and a Bimetallic Complex for Electrochemical Detection of Ascorbic Acid
(2021-02-01)
Octakis(3-chloropropyl)octasilsesquioxane (S) was organofunctionalized with the PAMAM Dendrimer G.0 (SPD). After functionalization, silsesquioxane interacts with copper chloride and subsequently with potassium hexacyanoferrate ...
Electrochemical study of arsenopyrite weathering
(Royal Soc Chemistry, 2003-01-01)
Cyclic voltammograms and capacitance measurements are presented to characterize the mineral response at relatively moderate environmental conditions, pH 4.5 and T = 25degreesC. The experiments involve examining the rates ...
The formation of anodic sulfide films on tin electrodes
(1990-01-01)
The electrodeposition of tin sulfide on polycrystaline tin from alkaline solution has been investigated using cyclic voltammetry. The first anodic peak in the cyclic voltammogram is associated with the deposition of a Sn ...
Mass/charge balance as a tool to estimate dimensional change in polypyrrole-based actuators
(Elsevier B.V., 2006-01-01)
The deconvolution of the voltammograms of polypyrrole electrochemistry has proved to be possible through the electrochemical quartz crystal microbalance data using the F(dm/dQ) function. This deconvolution allows the ...
Electrodeposited Pt-Ir electrodes: characterization and electrocatalytic activity for the reduction of the nitrate ion
(SPRINGER VERLAG, 1998-05)
The activity of Pt-Ir deposits on titanium for the reduction of the nitrate ion in 0.5 M perchloric acid was studied. The electrodes were characterized by SEM-EDAX, XPS and cyclic voltammetry. The activity of the electrodes ...
Voltammetric behaviour of nitrofurazone, furazolidone and other nitro derivatives of biological importance
(Royal Society of Chemistry, 1987)
In piridine - formic acid buffer and tetramethylammonium chloride solution of pH 4.5 at a dropping mercury or a glassy carbon electrode, nitrofurazone, furazolidone and nitrofurantoin are reduced in a single six-electron ...
