Cyclic voltammetry is a fundamental experimental method for characterizing electrochemical surfaces. Despite its wide use, a way to quantitatively and directly relate cyclic voltammetry to ab initio calculations has been lacking. We derive the cyclic voltammogram for H on Pt(111) and Pt(100), based solely on density functional theory calculations and standard molecular tables. By relating the g...

A detailed study using the cyclic voltammogram was done on the live cells of Aspergillus terreus. The peak current values were obtained for different days of growth and plotted against time. The response of cyclic voltammogram showed the phases of the growth of the fungus. The growth curve obtained matched well with the conventional methodology, which assesses the increase of dry weight of the ...

The electroreduction of COT in liquid ammonia at -38° and -65°C was investigated by cyclic voltammetric and controlled potential coulometric techniques. The results are interpreted by a two-step two-electron transfer reaction with strong ion-pairing of the COT dianion. Values for the heterogeneous electron transfer rate constants and the equilibrium constant of the disproportionation of the rad...

Both linear and cyclic derivatives of the cyclic 12-amino-acid antimicrobial peptide bactenecin were designed based on optimization of amphipathicity and charge location. In general, increasing the number of positive charges at the N and C termini and adding an extra tryptophan residue in the loop not only increased the activities against both gram-positive and gram-negative bacteria but also b...

The electrooxidation of benzylic alcohol derivative in acidic aqueous solution shows an oxidation pre-peak in the cyclic voltammogram, which means that the reaction is proceeding via an ECE mechanism where the second electron transfer occurs at a less positive potential. From the result of the rotating ring-disk electrode voltammetry, the initial oxidation response of the electrode reaction can...

Cyclic voltammogram of ionic liquid and metallic-salts in ionic liquids were recorded. Cu/Sn/Zn stacked layers were electrodeposited and subsequently sulfurized in a tube furnace in elemental sulfur at 550oC. Thin films were characterized by X-ray diffraction, ICP-MS, and SEM. The device was characterized by I-V, QE and Mott-Schottky (capacitance-voltage) plot.

Infinite square-tubular helices, [CuCl2(L)(S)] (L = bis(4-pyridyl)methylvinylsilane; S = Me2SO, HCONMe2), were constructed. This helical system affords three kinds of P, M crystals in Me2SO, and racemic crystals in HCONMe2. The cyclic voltammogram (CV) technique using the M-crystals is an effective tool for discerning the chirality of proline.
