Hydroquinone oxidation and p-benzoquinone reduction at polypyrrole and poly-N-methylpyrrole electrodes

Preparation of Poly-N-Methylpyrrole Coated Platinum Modified Electrode in Chloroform in the Presence of Various Supporting Electrolytes and Its Use for the Catalytic Oxidation of Ascorbic Acid and Hydroquinone

The electrochemical preparation of poly-N-methylpyrrole (PMPy) coated platinum electrode in chloroform in the presence of tetrabutylammonium Perchlorate, hexafluorophosphate, hydrogensulphate, Periodate and Iodide as supporting electrolytes was performed. The influence of electrosynthesis method, dopant anion type and operation temperature on electrochemical behavior of polymer were demonst...

Benzoquinone-Hydroquinone Couple for Flow Battery

At present, there is an ongoing search for approaches toward the storage of energy from intermittent renewable sources like wind and solar. Flow batteries have gained attention due to their potential viability for inexpensive storage of large amounts of energy. While the quinone/hydroquinone redox couple is a widely studied redox pair, its application in energy storage has not been widely explo...

XIX. Electrochemical Behavior at Polypyrrole-Nafion and Polypyrrole-Clay Thin Films on Glassy Carbon Electrodes

Biconductive films, involving the incorporation of an electronically conductive phase within an ionically conductive one, on glassy carbon electrode surfaces have been prepared by electropolymerization to form polypyrrole (PP) in matrices of Nation and the clay, hectorite. These films display electronic conductivity and higher stability than films of PP alone. Electrochemical studies of several...

Inhibition of human DNA topoisomerase II by hydroquinone and p-benzoquinone, reactive metabolites of benzene.

Chronic exposure of humans to benzene (BZ) causes acute myeloid leukemia (AML). Both BZ and therapy-related secondary AML are characterized by chromosomal translocations that may occur by inappropriate recombinational events. DNA topoisomerase II (topo II) is an essential sulfhydryl (SH)-dependent endonuclease required for replication, recombination, chromosome segregation, and chromosome struc...
