Electrochemical oxidation of 2’-deoxyguanosine-5’-triphosphate (dGTP) was investigated on the ionic liquid modified carbon paste microelectrode by cyclic voltammetry in this paper. The carbon ionic liquid microelectrode (mCILE) was prepared with ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate ([Emim][EtOSO3]) as the modifier. Then the electrochemical process of dGTP on the mCILE was recor...

This work reports the preparation, characterization and application as both electrochromic materials and electrochemical sensors of novel materials: carbon nanotubes/ruthenium purple nanocomposites. Using an innovative route based on a heterogeneous electrochemical reaction involving iron oxide species encapsulated within the cavities of the carbon nanotubes, the nanocomposite materials were ob...

Triazinedithiol polymeric nanofilm was prepared on a pure aluminum surface by electrochemical polymerization of AF17N. The mechanism of the process was proposed and electrochemical polymerization parameters were investigated. The triazinedithiol polymeric nanofilm had notable lubricity, high dielectric property and superhydrophobic property due to the allyl and fluoro alkyl groups in the AF17N ...

This investigation attempted to study electrochemical oxidation of formaldehyde at lower concentrations. Experiments were carried out in a batch electrochemical reactor using commercially available RuO2 coated titanium and SS as anode and cathode respectively and covering a wide range in operating conditions. Further, the statistical tool Response surface methodology by Box-Behnken design was u...

Corrosion inhibition of mild steel in 1 M HCl and 0.5 M H2SO4 by dapsone were studied by polarization resistance, Tafel polarization, electrochemical impedance spectroscopy (EIS) and weight loss measurement. Results obtained revealed that inhibition occurs through adsorption of the drug on metal surface without modifying the mechanism of corrosion process. Potentiodynamic polarization suggested...

A novel assay for the electrochemical detection of 4-nonylphenol (4-NP) based on carbon nanotubes modified screen-printed carbon electrodes (CNTs-SPCEs) has been investigated. The electrochemical behavior of the modified SPCEs and the mechanism of the oxidation of NP were investigated using cyclic voltammetry. The differential pulse voltammetry parameters were optimized for quantitative determi...

Performance criteria namely Material Removal Rate (MRR), Surface Roughness (SR) and Radial Over Cut (ROC) in electrochemical machining process greatly affected by the machining parameters like electrical parameters, electrode parameters, electrolyte parameters and workpiece properties. In the present work applied voltage (electrical parameter), tool feed rate (electrode parameter), electrolyte ...

Voltammetric studies of c-type cytochromes at clay-modified pyrolytic graphite electrodes have been undertaken as providing a good model for investigating interactions of proteins with soils. Different clays have been investigated according to their global charge, composition and hydrophobicity. The electrochemical behavior of either mitochondrial or bacterial cytochromes at these modified elec...

The authors have applied an advanced set of auto-regressive tools for identifying potentially complex, linear and nonlinear relationships in data, wherein the underlying physical relationships are not well described. In this paper these tools and techniques are described in detail, and the results of the application of these tools to evaluation of diesel engine lubricating oil health (based on ...

The inhibition effect of imidazole derivatives 4-methyl-2-propyl-1H-benzimidazole-6-carboxylic acid (MPBI) and 1,4'-Dimethyl-2'-propyl-1H,3'H-2,5'-dibenzimidazole (DPBI) against mild steel corrosion in 1 N HCl solutions were evaluated using conventional weight loss, potentiodynamic polarization, linear polarization and electrochemical impedance spectroscopy. The weight loss results showed that ...
