metallic copper nanoparticles modified glassy carbon electrode is fabricated by reduction of cuso4 in the presence of cetyltrimethylammonium bromide (ctab) through potentiostatic method. as-prepared nanoparticles are characterized by scanning electron microscopy and electrochemical methods. copper oxide modified glassy carbon electrode (nano-cuo/mgce) is prepared using consecutive potential sca...

in this work, a novel electrochemical technique is presented for determination of bentazonusing a nanocomposite based sensor and continuous coulometric fast fourier transformation cyclicvoltammetry (ccfftcv). in this method, the sensor response is in coulomb and is calculated based onintegrating charge changes under the current voltammogram in selected potential range. the new sensor wasconstru...

The composition of a polymeric potential-determining phase for ketoprofen selective electrode has been determined and the following basic electrode parameters were examined: measurement range, slope characteristic, limit of detection, response time, lifetime and selectivity coefficients in relation to some organic and inorganic anions. The electrode have been used for ketoprofen determination i...

A computer simulation of the extracellular field potential recording of nerve activity is presented. An experimental setup composed of an oscilloscope, a nerve, a conductive surface, and a recording electrode is graphically simulated. The user may study the influence of the position of the recording electrode and of certain nerve properties (membrane potential, velocity of conduction and action...
