The electrochemical behaviour of L-cysteic acid was studied at the surface of 1-[4-(ferrocenylethynyl)phenyl]-1-ethanone modified carbon paste electrode (4FEPEMCPE) in aqueous media using cyclic voltammetry and double step potential chronoamperometry. It has been found, that under optimum condition (pH 7.00) in cyclic voltammetry, the oxidation of L-cysteic acid at the surface of 4FEPEMCPE is o...

This study aims at evaluating the biocompatibility of titanium surfaces modified according two different ways: (i) deposition of a bio-inert, thin film of rutile TiO(2) by chemical vapour deposition (MOCVD), and (ii) biochemical treatment with collagen gel, in order to obtain a bio-interactive coating. Behind the comparison is the idea that either the bio-inert or the bio-active coating has spe...

The electrochemical stability of ceftriaxone (CFTX), belonging to the third generation cephalosporin antibiotics, was studied by measurements recorded on a platinum electrode (Pt) in aqueous solutions containing sodium halides. behavior investigated cyclic voltammetry (CV) and constant current density electrolysis assisted UV-Vis spectrophotometry. Cyclic highlighted that addition CFTX halide l...

An attempt has been made to investigate the effect of SiO2 nanoparticles on the conductivity of polypyrrole conducting polymeric films prepared by an electrochemical method. The obtained nanocomposites were characterized by FTIR, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). The results indicate that the conductivity of the nanoco...

We put forward a measure based on Gaussian steering to quantify the non-Markovianity of continuous-variable (CV) quantum channels. employ proposed assess and compare Brownian motion (QBM) channel, originating from interaction with Ohmic sub-Ohmic environments spectral densities described by Lorentz-Drude cutoff, both at high low temperatures, showing that sub-Ohmic, high-temperature lead highly...

The electrochemical behaviour of lead electrode in hydrochloride solution containing variousoxo-anions at different concentrations was studied by using of cyclic voltammetry (CV) method.Results obtained show that the addition of these inorganic compounds decreases the anodic andcathodic currents peaks according to the following order: H2PO4- > HPO42-> SO42-. It’s revealedalso that the cathodic ...

Let t, v, k, λ be positive integers satisfying v > k > t. A t-(v, k, λ) design is an ordered pair (V,B), where V is a finite set of v points, B is a collection of k-subsets of V , say blocks, such that every t-subset of V occurs in exactly λ blocks in B. In what follows we simply write t-designs. A 3-(v, 4, 1) design is called a Steiner quadruple system and denoted by SQS(v). It is known that a...
