TL;DR: The voltammetric oxidation of all deoxyribonucleic acid (DNA) monophosphate nucleotides is investigated for the first time over a wide pH range by differential pulse voltammetry with a glassy carbon electrode.

TL;DR: In this article, a vanadium chloride/polyhalide redox flow cell is described, which employs a polyhalide solution in the positive half-cell electrolyte and a V(II)/vanadium(III) chloride redox couple as the negative half-cells electrolyte.

TL;DR: In this paper, cyclic voltammetry (CV) was used to study thin films of the fullerenes C{sub 60} and C {sub 70} formed by solution casting, in MeCN solutions containing quaternary ammonium or alkali-metal salts as supporting electrolytes.
Abstract: Thin films of the fullerenes C{sub 60} and C{sub 70}, formed by solution casting, were studied by cyclic voltammetry (CV) in MeCN solutions containing quaternary ammonium or alkali-metal salts as supporting electrolytes. The film shows four CV reduction waves and one oxidation wave. The CV behavior for the first reduction, coulometrically equivalent to a one-electron reduction, indicates a large structural reorganization of the film with intercalation of the supporting electrolyte cation and a small amount of dissolution. Upon oxidation of the reduced form, the structure rearranges to form the parent. Similar effects occur for the second reduction/reoxidation process. The size of the cations affects the nature of these CV waves. Scanning electrochemical microscopy (SECM) of the C{sub 60} films indicates that neither the C{sub 60} film nor the completely reduced, C{sub 60}{sup -}, form is a good electronic conductor, while a partially reduced film displays enhanced conductivity. Langmuir trough studies of C{sub 60} and C{sub 70} show the preparation of highly incompressible monolayer and multilayer films at the air/water interface. Mixed films of the fullerenes with the surfactant arachidic acid can also be prepared. 42 refs., 18 figs., 1 tab.

TL;DR: In this paper, a dependence of the PPy growing rate on the pore size and on the electrolyte nature and concentration has been observed, and the morphology of different template-synthesized nanostructures has been carefully analyzed by fieldemission scanning electron microscopy.
Abstract: Polypyrrole (PPy) with four different counterions was electrochemically synthesized in homemade polycarbonate particle track-etched membranes with different pore sizes. A dependence of the PPy growing rate on the pore size and on the electrolyte nature and concentration has been observed. The morphology of the different template-synthesized nanostructures has been carefully analyzed by field-emission scanning electron microscopy. In all cases, nanotubules were observed. However, their thickness depends on the pore diameter of the template membrane and on the nature of the supporting electrolyte. The electrical conductivity of PPy in such a structure is known to increase compared to the bulk conductivity, which is also shown here. In addition Raman spectroscopy showed that the relative conjugation length increases with decreasing pore size.

TL;DR: In this paper, it was shown that in neutral aqueous solutions, the product of H 2 O 2 electrocatalytic reduction is OH − − − 2, and that the operational stability of Prussian Blue in H 2O 2 reduction was highly dependent on the buffer capacity of the supporting electrolyte.
