Abstract Bi(III) ions electroreduction in the presence of N-acetylcysteine (ACYS)at nanostructured R-AgLAFE electrode has been studied by voltammetric and impedance measurements. The experimental data indicates multistage character process catalytic influence on rate. It was found that this is controlled chemical reaction Bi(III)–Hg(SR) 2 activecomplexes formation surface, which mediates electr...

The electrocatalytic oxidation of formic acid at a gold electrode functionalized with FePt nanoparticles was studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in a mixed solution of 0.1 M HCOOH and 0.1 M HClO4. The FePt bimetallic nanoparticles, with a mean diameter of 3 nm, were prepared by a chemical reduction method. The Au/FePt nanostructured electrode was ...

Herein, the effects of nanostructured modifications a gold electrode surface in development electrochemical sensors for L-ascorbic acid detection have been investigated. In particular, bare has modified by electrodeposition single-walled carbon nanotubes (Au/SWCNTs) and formation highly nanoporous (h-nPG) film. The procedure realized sweeping potential between +0.8 V 0 vs. Ag/AgCl 25 scans susp...

INTRODUCTION The research made in this PhD thesis fits the current trend in the development of new advanced composite electrode materials with high performance and parameters. The composite materials has new physical and chemical properties that are not present in its components taken individually. The new electrode materials were obtained by combination of conducting polymers, such as polypyrr...

The process of removing indium ions from aqueous solutions by applying capacitive deionization (CDI) is reported in this manuscript. First, a modified carbon material was prepared incorporating titanium dioxide (TiO2) into activated (AC). A microwave-assisted ionothermal synthesis (MAIS) method used to produce evenly distributed nanostructured anatase TiO2 on the surface AC. polyurethane (PU) e...

Nanostructured geometry on carbonaceous material surface induce thin liquid layer formation. • We provide a well-controlled carbon system to study thin-liquid-layer effects. Our model probes only geometrical factors – no chemical effects are present. show that we can still apparent electrocatalysis. validate these and not If proper diagnostics used, remain unnoticed. Here use an electrode consi...

conventional and nanostructured ysz coatings were deposited on the in-738 ni super alloy by the atmospheric plasma spray technique. the oxidation was measured at 1100°c in an atmospheric electrical furnace. according to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. the improved oxidation resistance of the nanocoating could ...

The extensive physiological and regulatory roles of nitric oxide (NO) have spurred the development of NO sensors, which are of critical importance in neuroscience and various medical applications. The development of electrochemical NO sensors is of significant importance, and has garnered a tremendous amount of attention due to their high sensitivity and selectivity, rapid response, low cost, m...
