Electrochemical properties of transition metal complexes are important parameters that should be considered for the successful application these compounds in catalytic reactions. The proper choice ligands and type its coordination allow construction a catalyst with high performance. reversibility complex oxidation is prerequisite participation redox catalysis, while potential values correlate r...

Copper electroless plating at low pH (7–9) using dimethylamine borane complex as a reducing agent is studied electrochemically by linear sweep voltammetry, cyclic voltammetry and chronopotentiometry in full electrolytes. We find that the mixed potential theory is not applicable to the described system. We show that both the working potential and the rate-controlling mechanism are dependent on t...

The applicability of differential pulse voltammetry (DPV) and adsorptive stripping voltammetry (AdSV) at a non-toxic meniscus-modified silver solid amalgam electrode (m-AgSAE) for the determination of trace amounts of genotoxic substances was demonstrated on the determination of micromolar and submicromolar concentrations of 3-nitrofluoranthene using methanol 0.01 mol L NaOH (9:1) mixture as a ...

Cyclic voltammetry is a fundamental experimental method for characterizing electrochemical surfaces. Despite its wide use, a way to quantitatively and directly relate cyclic voltammetry to ab initio calculations has been lacking. We derive the cyclic voltammogram for H on Pt(111) and Pt(100), based solely on density functional theory calculations and standard molecular tables. By relating the g...

BACKGROUND Dopamine is a potent neuromodulator in the brain, influencing a variety of motivated behaviors and involved in several neurologic diseases. Measurements of extracellular dopamine in the brains of experimental animals have traditionally focused on a tonic timescale (minutes to hours). However, dopamine concentrations are now known to fluctuate on a phasic timescale (subseconds to seco...

The interaction of phospholipid membranes and oligonucleotides complexed with a positively charged surfactant is reported. Phospholipid membranes were assembled at the interface between an immobilized organic phase and an aqueous phase using the Langmuir-Blodgett (L-B) technique. The interaction and adsorption of the naked oligonucleotides and oligonucleotides complexed with cetylpyridinium chl...

The electrochemical oxidation of labetalol was investigated by cyclic, linear sweep and differential pulse voltammetry at carbon paste electrode in Britton—Robinson buffers over the pH range 2.0—10.0. For analytical purposes, a well-defined adsorption-controlled anodic peak was obtained in Britton—Robinson buffer at pH 2.0. By anodic adsorptive linear sweep and differential pulse voltammetry, l...
