The iodination of proteins remains a useful tool in biochemistry for radiolabelling. However, chemical or enzymatic iodination is difficult to control and can give deleterious polyiodination. Previously, we have shown that electrooxidation with nitrite is a rapid method for the selective nitration of tyrosine residues in proteins. In principle, it should be possible to substitute a number of el...
we explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized tio2 matrix. these electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to tio2 nanotubes, respectively. titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (eg) fluoride-c...
A sodium dodecyl sulfate modified carbon paste electrode (SDS/CPE) was developed in this work based on the surface modification method. The modified electrode was prepared by immersing SDS/CPE in a nickel nitrate solution. This electrode showed a strong accumulation ability toward nickel ions. Then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 V (vs. ...
In this study, Pd/C, Cu/C, and a series of PdCu/C bimetallic electrocatalysts were prepared by microwave-assisted modified polyol method to determine glycerol electrooxidation reaction (GOR) activities. The effect microwave duration on catalyst structure GOR activity was investigated catalysts. Also, commercial Pd/C (com-Pd/C) used compare catalytic activities with samples. Electrocatalysts cha...
The different weight ratios of Pd to Pt, i.e., 16:4, 10:10, 4:16 in Pd-Pt/C and (20 wt. %)/C electrocatalysts with low metal loading were synthesized for glycerol electrooxidation an air breathing microfluidic fuel cell (MFC). performance on Pd-Pt (16:4)/C anode electrocatalyst was found best among all the tested. single when tested at a temperature 35°C using (16:4)/C, showed maximum open cir...
Abstract The present experimental study used a successful advanced electrochemical oxidation process (AEOP) and parallel-plate reactor to investigate the potential of (EO) treatment method for real produced wastewater by Al-Samawah petroleum refinery. In oxidation, several electrodes type were employed, with carbon felt graphite plate serving as anode. Tests total organic compounds chemical oxy...
Electrooxidation of urea plays a substantial role in the elimination urea-containing wastewater and industrial urea. Here, we report electrodeposition nickel hydroxide catalyst on commercial carbon paper (CP) electrodes from dimethyl sulphoxide solvent (Ni(OH)2-DMSO/CP) for electrooxidation under alkaline conditions. The physicochemical features Ni(OH)2-DMSO/CP catalysts using scanning electron...
Durable, highly efficient, and economic sound electrocatalysts for CO electrooxidation (COE) are the emerging key for wide variety of energy solutions, especially fuel cells and rechargeable metal-air batteries. Herein, we report the novel system of nickel-aluminum double layered hydroxide (NiAl-LDH) nanoplates on carbon nanotubes (CNTs) network. The formulation of such complexes system was to ...
The electrochemical behaviour of tobacco mosaic virus (TMV) and its isolated protein was studied using differential pulse (DP) voltammetry at a graphite electrode and by direct current (DC) polarography in Brdicka solution. TMV and its isolated protein were found to be electrooxidized at the graphite electrode in the adsorbed state. Both species yielded two oxidation peaks on DP voltammograms. ...
