Based on the damage of natural DNA, a 3-input/4-output logic gate system and other biomacromolecular devices, such as a 2-to-1 encoder, a 1-to-2 decoder and a keypad lock, were developed using simultaneously obtained electrochemiluminescence (ECL) and cyclic voltammetry (CV) signals as outputs in the presence of Ru(bpy)3(2+).

Herein, we reported for the first time one step procedure for the preparation of cytochrome c (cyt c)-poly (5-amino-2-napthalenesulfonic acid) (PANS)modified glassy carbon electrode by cyclic voltammetrically (CV). Hereafter, we called the above modified electrode as cyt c-PANS electrode. The presence of cyt c on m co m vailable online 8 August 2008

The Cyclic Voltammetry (CV) was used to investigate the electrochemical behavior of alizarin yellow R and some analogous arylazo compounds having almost the same central azo group. For this purpose, the substances chosen for the measurements are Alizarin Yellow R (AYR), Eriochrome Black T (EBT) and Sudan II (SUD II). The investigations were carried out at room temperature (298 K) in both aqueou...

The ionization potentials (IPs) and electron affinities (EAs) of widely used conjugated polymers are evaluated by cyclic voltammetry (CV) in conventional electrochemical and lithium-ion battery media, and also by ultraviolet photoelectron spectroscopy (UPS) in vacuo. By comparing the data obtained in the different systems, it is found that the IPs of the conjugated polymer films determined by c...

BACKGROUND Structural myocardial abnormalities have been extensively documented in hypothyroidism. Experimental studies in animal models have also shown involvement of thyroid hormones in gene expression of myocardial collagen. This study was planned to investigate the ability of ultrasonic tissue characterization, as evaluated by integrated backscatter (IBS), to early identify myocardial invol...

An automatic procedure for the extraction of quantitative parameters which characterize the Cyclic Variation (CV) of ultrasonic Integrated Backscatter Signal (IBS) within the cardiac cycle is proposed. Ajier image realignment, the following CV parameters are quantified for each pixel, by harmonic analysis of the corresponding pixel intensity along the cardiac cycle: the modulus of the first (AO...

The insulating properties of self-assembled thiolipid monolayers and tethered lipid bilayers on polycrystalline gold electrodes were studied by means of cyclic voltammetry (CV). These films were formed by two-step self-assembly processes. Electrochemical measurements of the heterogeneous electron transfer rate constant of different redox couples such as potassium ferrocyanide (K(4)[Fe(CN)(6)]) ...

Polypyrrole nanoparticles were synthesized by chemical polymerization method using ammonium persulphate as an oxidant. The synthesized polypyrrole nanoparticles were characterized by FT-IR, UV-Visible, FESEM and CV. The structure of polypyrrole nanoparticles were confirmed by FT-IR spectroscopy. The UV-Vis spectra of polypyrrole nanoparticles show π-π* and n-π* transitions. The morphological pr...

The electrochemical interaction of oxide ions with tungsten electrodes in molten calcium chloride (CaCl2) was analyzed by combining electroanalytical techniques X-ray photoelectron spectroscopy. During a cyclic voltammetry (CV) scan, the appear to interact working electrode via multi-step oxidation and reduction process. overall redox peaks behave reversibly up 750 mV s?1. This process enables ...
