There are various ways to impose a potential variation in time, and subsequently a series of voltammetric methods. Cyclic voltammetry relies on linearly scanning the potential in time, observing a triangular waveform variation [1-3]. Differential pulse voltammetry is based on two samplings of the current intensity for each potential pulse: one measurement before applying the pulse, and the seco...

In this review, we focus on cyclic voltammetry as a reliable electrochemical technique to study mechanisms, kinetics and thermodynamics of various types of drug-drug interactions. While we present and discuss six theoretical models relevant to analyze drug-drug (or drug-DNA) interactions, we also give hints about recent experimental achievements in this field. In addition, we provide the reader...

the reduction mechanism of molybdenum-methyl thymol blue (mtb)-chlorate system has been investigated in water on a mercury electrode. as this system is very sensitive for ultratrace determination of molybdenum, the actual mechanism involved was studied. electrochemical techniques, including dc tast polarography and cyclic voltammetry were employed. it is shown that, the cathodic wave of molybde...

the electrochemical oxidation of sulfamethazine (smz) has been studied at a multi-walled carbon nanotubes modified glassy carbon electrode (mwcnt-gce) by cyclic voltammetry. this modified electrode (mwcnt-gce) exhibited excellent electrocatalytic behavior toward the oxidation of smz as evidenced by the enhancement of the oxidation peak current and the shift in the anodic potential to less posit...

the adsorptive behavior of the immunosuppressive agent tacrolimus was studied by cyclic and differential-pulse voltammetry on a hanging mercury drop electrode (hmde). the drug was accumulated at hmde and two well-defined peak currents were obtained at -1353 and -1417 mv vs . sce (saturated kcl) in borate buffer (ph 10.0) + 0.1 kcl solution. a voltammetric procedure was developed for the determi...

In this study, simple, fast and reliable cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV) methods were developed and validated for determination of bosentan in pharmaceutical preparations. The proposed methods were based on electrochemical oxidation of bosentan at platinum electrode in acetonitrile solution containin...

In this paper, we present an e cient FFT based signaling scheme for Multimedia Steganography. The use of FFT permits the use of signal sets of large dimensions without increasing the computational complexity drastically. This is achieved by generating the maximally separable points of the signal constellation in such a way that detection is implemented through an FFT based cyclic correlation. I...
