A bienzymatic biosensor incorporating a mediator has been developed in order to achieve a fast and selective detection of glucose in a flow injection system. The working electrode is based on a carbon paste matrix bulk modified with glucose oxidase (GOD) and horseradish peroxidase (HRP) as well as with ferrocene acting as an electron transfer mediator between the electrode and HRP. The proximit...

The conditional formal potential, E°′of Methyldopa has been studied by cyclic voltammetry at the surface of activated glassy carbon electrode (AGCE) as the working electrode in different pH phosphate buffered solutions. The experimental Standard redox potential, E°′, of Methyldopa is obtained to be 0.72 mV versus SHE (Standard Hydrogen Electrode). E°′ values have also been calculated with the a...

An electrochemical method employing a carbon nanocomposite electrode was developed to measure thioridazine. The electrode has been designed by incorporation of montmorillonite nanoclay into the carbon ionic liquid electrode. Surface morphology of the electrodes was done using scanning electron microscopy. Adsorptive stripping voltammetry was applied as a very sensitive analytical method for...

This work describes the fabrication, characterization, and application of a gold microband array electrode (MAE) for the determination of phosphate in fresh water samples. The working principle of this MAE is based on the reduction of a molybdophosphate complex using the linear sweep voltammetric (LSV) method. The calibration of this microsensor was performed with standard phosphate solutions p...

We have fabricated a dye-sensitized solar cell (DSSC) with a pair of carbon-based electrodes using a transparent, conductive carbon nanotubes (CNTs) film modified with ultra-thin titanium-sub-oxide (TiOx) as the working electrode and a bilayer of conductive CNTs and carbon black as the counter electrode. Without TiOx modification, the DSSC is almost nonfunctional whereas the power conversion ef...

Specially designed five-electrode cells contained two types of mixed ionic-electronic conductor ~MIEC! lithium-insertion anodes. These were graphite or Sn1.3Al0.3Ti1.7O1.95(PO4)3 tin composite oxide ~TCO! bonded powders sandwiched between nickel mesh current collectors as working lithium-ion anodes, with Li foils on both sides as reference electrodes, outside of which were two further Li foils,...

A PVC membrane Ni(II) ion selective electrode has been constructed using (1E,2E)-bis(2-aminophenyl)N'1,N'2-dihydroxyethanebis as membrane carrier. The electrode exhibited a goodpotentiometric response for Ni(II) over a wide concentration range 1.0×10-4 to 1.0×10-1M with aslope of 29.4±0.5 mV/decade a and a working pH range of 6.5-9.0. It had a fast response time of≤20s. The best performance was...
