metallic copper nanoparticles modified glassy carbon electrode is fabricated by reduction of cuso4 in the presence of cetyltrimethylammonium bromide (ctab) through potentiostatic method. as-prepared nanoparticles are characterized by scanning electron microscopy and electrochemical methods. copper oxide modified glassy carbon electrode (nano-cuo/mgce) is prepared using consecutive potential sca...

In this work, poly (o-Anisidine) (POA) was prepared by consecutive potential cycling in an acidic monomer solution at the surface of Carbon Paste Electrode (CPE). Nickel ions were dispersed into the polymer by immersing the electrode in NiSO4 solution. The prepared Ni/POA/CPE was characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, Atomic Force Mic...

The scanning electrochemical microscope (SECM) was used to characterize the atomic layer deposition (ALD) of TiO2 on indium-doped tin oxide (ITO) substrates by studying electron transfer through pores in the thin films (1−5 nm thickness). The extent of electron transfer, and thus the porosity of the films, was evaluated by transient electrochemistry. These studies show that ALD deposition of Ti...

Thin films of conducting molecularly imprinted polymers (MIPs) were prepared for simultaneous chronoamperometry (CA) and piezoelectric microgravimetry (PM) determination of several explosive nitroaromatic compounds (NTs) including 2,4,6-trinitrophenol (TNP), 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitrobenzene (TNB), and 2,4-dinitrotoluene (DNT). For that, the bis(2,2'-bithienyl)-(4-aminophenyl)m...

This study examined the effects of mist generated from NaCl solution on electrochemical properties polymer electrolyte membrane fuel cells. Mist-containing Na+ and Cl- ions were using a custom-made generator. The current density-voltage-power density curves impedance spectroscopy cells systematically achieved. Furthermore, long-term stability experiments carried out chronoamperometry mode for 2...

An amperometric horseradish peroxidase (HRP) inhibition biosensor has been substantially constructed by the help of N,N-dicyclohexylcarbodiimide (DCC), N-hydroxysuccinimide (NHS). The preparation steps and the biosensor response to phenylhydrazine were monitored by electrochemical impedance spectroscopy (EIS), cyclic voltammetry, and chronoamperometry. The proposed biosensor could be applied to...

In this paper, a pencil graphite electrode was pretreated using chronoamperometry technique in phosphate buffer solution (pH=7.0) for sensitive determination of quercetin. Oxidation of quercetin was investigated using pretreated pencil graphite electrode and anodic stripping differential pulse voltammetry. Under optimal conditions, the anodic current of quercetin exhibited linear response to it...
