Electrochemical Degradation of the Pesticide Dimethenamid-P at Gold, DSA Platinum and Ruthenium Oxide Electrodes in Different Electrolytes
(Wiley-Blackwell, Malden, 2014)
For the first time the electrochemical degradation of the pesticide dimethenamid-P was studied. Its direct electrochemical degradation, using potential cycling at a gold electrode, was performed by cyclic voltammetry and ...
Morphology and capacitive properties of [RuOxH y/low-surface area carbon black] composite materials prepared by sol-gel procedure
(Materials Science Forum, 2005)
The morphology and the capacitive properties of carbon supported hydrous ruthenium oxide (RuOxHy/C), prepared by impregnation of low-surface area carbon black Vulcan® XC-72 R with solid phase of RuO xHy sol, were investigated ...
Electrochemical monitoring of the breast milk quality
(Elsevier, 2018)
The electrochemical techniques were used to determine the total antioxidant capacity of breast milks and the results were compared with a commonly used spectrophotometric (2,2-diphenyl-1-picrylhydrazyl, DPPH) method. Breast ...
Synthesis and biological activity of derivatives of the marine quinone avarone
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2010)
Nine alkyl(aryl)thio derivatives of the marine sesquiterpene quinone avarone were synthesized by nucleophilic addition of thiols or thiophenol to avarone. In most cases only one regioisomer was obtained. Their cytotoxic ...
Comparative Electrochemical Determination of Total Antioxidant Activity in Infant Formula with Breast Milk
(Springer, New York, 2014)
The aim of this study is to investigate the significance of breast milk and infant formula in the prevention of oxidative stress, by electrochemical determination of the total antioxidant potential, demonstrating the ...
Study of ellagic acid electro-oxidation mechanism
(Springer Wien, Wien, 2013)
Ellagic acid is a biologically active polyphenol found in numerous fruits and vegetables. However, not many papers dealing with the electrochemical properties and protolytic equilibria of ellagic acid have been published ...
Electrochemical, theoretical, and morphological studies of antioxidant fullerosteroids
(Springer Wien, Wien, 2014)
Four fullerosteroidal conjugates, previously confirmed to express two- to threefold better antioxidant activity in vitro than C-60, were subjected to additional studies, including electrochemical, theoretical, and morphological ...
Synthesis, Electrochemistry, and Hierarchical Self-Organization of Fulleropyrrolidine-Phthalimide Dyads
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
A series of novel fulleropyrrolidine-phthalimide dyads was synthesized and their electrochemical and self-assembly properties were investigated. Efficient synthesis of acceptor-acceptor dyads was performed under microwave ...
The qualitative electrochemical determination of clarithromycin and spectroscopic detection of its structural changes at gold electrode
(Elsevier, 2007)
The aim of the present study was the qualitative determination of the pure clarithromycin using a gold electrode in neutral electrolyte by cyclic linear sweep voltammetry. It was shown that in the range of -1.2 V to 1.0 V ...
Ru layers electrodeposited onto highly stable Ti2AlC substrates as cathodes for hydrogen evolution in sulfuric acid solutions
(Elsevier, 2016)
In this work, the hydrogen evolution reaction (HER) was studied on Ru coated Ti2AlC electrodes in 1.0 mol dm(-3) H2SO4 at 25 degrees C. Ti2AlC was found to be a highly stable substrate in sulfuric acid solutions due to the ...
