The development of an electrochemical detector to monitor the in situ formation of biofilms is described. The detector consisted of an electrochemical cell containing three electrodes, whose response to the application of a potential profile to the working electrode was sensitive to the amount of biofilm present on the surface. The electrochemical technique used was repetitive cyclic voltammetr...

This work presents for the first time the electrochemical determination of europium using cyclic voltammetry at gold electrodes modified with 2-pyridinol-1-oxide. A well-defined oxidation peak was observed in cyclic voltammetry as a result of the oxidation of the europium at ∼1100 mV in phosphate buffer at pH 7.0. The peak current increased linearly with the increase of concentration of the eur...

Discrete Fourier transforms (DFTs) over finite fields have widespread applications in error correction coding [1]. For Reed-Solomon (RS) codes, all syndrome-based bounded distance decoding methods involve DFTs over finite fields [1]: syndrome computation and the Chien search are both evaluations of polynomials and hence can be viewed as DFTs; inverse DFTs are used to recover transmitted codewor...

The glassy carbon electrode was modified with Pd particles using a conducting poly(thionine) as the support material. Polymerization of thionine carried by electrochemical process from aqueous acetate solution cyclic voltammetry. K2PdCl4 used precursor and immobilization performed constant potential electrolysis. characterized electrochemically voltammetry impedance spectroscopy methods. result...
