Studies on electrochemical oxidation of azithromycin and Hemomycin (R) at gold electrode in neutral electrolyte
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
The aim of the present study was to examine the oxidative properties and an assay of azithromycin and Hemomycin (R) at a gold electrode in neutral electrolyte using cyclic linear sweep voltammetry. The maximum value of the ...
Polypyrrole as possible electrode materials for the aqueous-based rechargeable zinc batteries
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Polypyrrole (PPy) thin film electrode was galvanostatically synthesized and characterized in 0.1 M HCl on graphite electrode as cathode materials for the aqueous-based rechargeable zinc batteries. The charge/discharge ...
Kinetic investigations of the electrochemical bromination of peracetylated D-glucal in organic solvents
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Cyclic voltammetry and ultramicroelectrodes were used to investigate the kinetic aspects of the electrochemical bromination of 3,4,6-tri-O-acetyl-D-glucal (1) in acetonitrile (AN), dichloromethane (DCM), and dimethylsulfoxide ...
Catalysis of oxygen reduction on Au modified by Pd nanoislands in perchloric acid solution
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Oxygen reduction reaction (ORR) was studied on polycrystalline gold, Au(poly), modified by nanosized palladium islands in 0.1 M HClO4 solution using rotating disc electrode technique. Paladium was spontaneously deposited ...
First electrochemistry of herbicide pethoxamid and its quantification using electroanalytical approach from mixed commercial product
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
This work present a new approach for the detection of relatively new herbicide pethoxamid (POA), a first electrochemical behavior and determination based on its oxidation on boron-doped diamond electrode in Britton-Robinson ...
Catalysis of hydrogen evolution on different Pd/Au(111) nanostructures in alkaline solution
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Hydrogen evolution reaction (HER) was studied on Pd/Au(1 1 1) bimetallic surfaces in alkaline solution. Au(1 1 1) was modified by palladium nanoislands spontaneously deposited using PdSO4 center dot 2H(2)O and PdCl2 salts. ...
Synthesis and characterization of AgPd alloy coatings as beneficial catalysts for low temperature fuel cells application
(Elsevier, 2019)
The Ag, Pd and AgPd alloys of different morphologies and compositions were electrodeposited onto Au
and glassy carbon (GC) disc electrodes from the solution containing 0.001 M PdCl2 þ 0.04 M AgCl þ 0.1 M
HCl þ 12 M LiCl ...
Voltammetric and differential pulse determination of roxithromycin
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
The oxidative behavior of antibiotic roxithromycin standard was studied at a gold electrode in 0.05 M NaHCO3 using cyclic linear sweep voltammetry and differential pulse voltammetry. It was found that the value of the ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt"Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
Mechanically activated carbonized rayon fibers as an electrochemical supercapacitor in aqueous solutions
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
The activated carbon cloth (ACC), obtained by chemical/physical activation of carbonized rayon fibers, was grinded in a ball mill and studied from the aspect of double layer capacitance. The changes in pore structure, ...
