A simple column electrode, S-CE, with a glassy carbon fibers working electrode stuffed into a Teflon tube was developed. The current-potential curves for the reductions of [Fe(CN)(6)](3-) and Fe(3+) observed at the S-CE were analyzed based on a theory for those at an ordinary column electrode. A quantitative electrolysis was performed at the S-CE rapidly within 20 s. An accurate and precise cou...

The electrochemical reduction of benzalacetone (BA) has been studied at mercury cathodes in N,N-dimethylformamide solutions by the techniques of cyclic voltammetry and controlled potential coulometry. The radical anion (BA'-) forms ion pairs with tetraethylammonium cations and then disappears in oligomerization processes. Atentative structureof the dimer BA BA"-... (C2H5)4N+is suggested on the ...

The electrochemical behavior of Ar(2)SeCl(2), and Ar(2)Se(2), (Ar:CH(3)OC(6)H(5); C(2)H(5)OC(6)H(5)) in acetonitrile (AN) containing tetrabutylammonium tetrafluoroborat (TBAFB) as supporting electrolyte was studied on a stationary electrode (spe). In order to elucidate the electrode reactions linear potential scan, cyclic voltammetry and controlled-potential coulometry were employed using a pla...

Superparamagnetic nanoparticles (NPs) are used in a variety of magnetic field-assisted chemical and medical applications, yet little of their fate during magnetic field interrogation is known. Here, fundamental and new insights in this are gained by cathodic particle coulometry. This methodology is used to study individual Fe3O4 NPs in the presence and absence of a magnetic field. It is first n...
