The electrodeposition of tin, bismuth, and tin-bismuth alloys from SnII and BiIII chlorometalate salts in the choline chloride/ethylene glycol (1:2 molar ratio) deep eutectic solvent was studied on glassy carbon and gold by cyclic voltammetry, rotating disc voltammetry, and chronoamperometry. The SnII-containing electrolyte showed one voltammetric redox process corresponding to SnII/Sn0. The di...

The perfluorinated polycationic polymer Tosflex @ is used for preparing polymer modified electrodes able to preconcentrate and detect the anionic complex HgCl$-, which is the prevailing inorganic Hg(II) species in sea water and other chloride media. The study of the ion-exchange voltammetric behaviour of the tetrachloromercurate(I1) complex at Tosflex-modified electrodes indicates the efficient...

Self-assembled monolayers and bulk films of thioanilines, polymerized on gold and platinum surfaces, have been characterized and compared to bulk polyaniline (PANI) films. In a previous study [Kuwabata; et al. Langmuir 1999, 15, 6807-6812], only one redox couple was observed in the cyclic voltammetric profile of a polymerized monolayer of thioaniline on gold, in contrast to the known profiles o...

The electrochemistry of pyrazine, quinoxaline, phenazine, and solvated electrons in near-critical and supercritical ammonia was investigated by cyclic voltammetry and chronoamperometry and compared to that in liquid ammonia at -40 OC. The reductions of pyrazine, quinoxaline, and phenazine at room temperature, and in the supercritical fluid (SCF), occur reversibly or quasi-reversibly and result ...

Voltammetric scanning electrochemical cell microscopy (SECCM) incorporates cyclic voltammetry measurements in the SECCM imaging protocol, by recording electrochemical currents in a wide potential window at each pixel in a map. This provides much more information compared to traditional fixed potential imaging. Data can be represented as movies (hundreds of frames) of current (over a surface reg...

Building on diamond characteristics such as hardness, chemical inertness and low electron emission threshold voltage, the current microscopic, spectroscopic and voltammetric investigations are directed towards improving the properties of electrode coating materials for their future use in clinical studies of deep brain stimulation via fast-scan cyclic voltammetry (FSCV). In this study we combin...

The molecular dynamics and density functional theory (DFT) can be applied to discriminate electrocatalyst’s electron transfer (ET) properties. It will interesting the ET properties of green electrocatalysts such as amino acids. Here, we have used DFT compare electrocatalytic abilities asparagine glutamine at carbon paste electrode interface. Cyclic voltammetric results reveal that activities as...

A thin film of epinephrine (EP) was electrochemically deposited on the surface of glassy carbon electrode previously activated in NaHCO3 solution. The cyclic voltammograms of the modified electrode indicate that the surface confined EP are strongly dependent on the solution pH, as expected for quinone/hydroquinone functionalities. The EP-modified glassy carbon electrode exhibited...

New highly sensitive voltammetric DNA-sensors have been developed for the detection of cytostatic drug doxorubicin based on Azure A electropolymerized various carbon nanomaterials, i.e., functionalized multi-walled nanotubes (fMWCNTs) and black (CB). Carbon materials promote electropolymerization dye applied as a matrix DNA molecules saturated with methylene blue (MB) molecules. Interaction int...
