Conformation by electrochemistry Electrochemistry is rarely thought of as a technique for determining structures of biomolecules. Nevertheless, because it is a much simpler and less expensive method than traditional structure-determining approaches such as NMR, MS, and X-ray diffraction, electrochemistry is certainly worth developing for conformational analysis. This is exacdy what Janet G. Ost...

The electrochemistry of the Fe3+/2+ redox couple has been studied on highly oriented pyrolytic graphite (HOPG) samples that differ in step edge density by 2 orders of magnitude, to elucidate the effect of surface structure on the electron transfer (ET) kinetics. Macroscopic cyclic voltammetry measurements in a droplet-cell arrangement, highlight that the Fe3+/2+ process is characterised by slow...

A new series of ruthenium polypyridyl complexes with a hydroxypyridine ligand were prepared, and their properties were investigated spectroscopically and electrochemically. Particular focus is paid to the effects of protonation-deprotonation and ethylation of the hydroxypyridine ligand, which affects the NMR, electronic spectroscopy, and electrochemistry of the complex. The changes to the UV-vi...

A mixed-valence diruthenium complex, whose metal centres were triply bridged by one chloro and two methoxo ligands, was synthesized and characterized by X-ray structural analysis, electrochemistry and spectroscopy, and its mixed-valence state was classified into Class III.

A liquid chromatography/mass spectrometry (LC/MS) method using desorption electrospray ionization (DESI) as a versatile interface has been established, which allows a wide range of elution flow rates, online derivatization via reactive DESI and further combination with electrochemistry.

graphene modified glassy carbon electrodes have been developed for the determination of calcium dobesilate in pharmaceutical formulations. the prepared graphene and cnts were used as a conductive substrate for electrochemical study of calcium dobesilate. the direct electrochemistry of calcium dobesilate showed a reversible cyclic voltammogram with a formal potential of 133 mv (vs. ag/agcl) for ...
