A stable electroactive thin film of cobalt hexacyanoferrate (COHCF) was electrochemically deposited on the surface of a microband gold electrode. The cyclic voltammograms of CoHCF film indicate the presence of two redox peaks corresponding to the hexacyanoferrate(II/lII) redox couple. The electrochemical behaviour of CoHCF is related to the concentration of supporting electrolyte and counter-io...

A new type of solid state solar cell is produced by using Fe2O3 (working electrode) and SiC as a hole collector (counter electrode). Two molten salts, 1-ethyl-3-methylimidazolium chloride (EMICl) and 1-butyl-3-methylimidazolium iodide (BMII) were used as crystal growth inhibitors with a SiC film. It was found that BMI1 shows about 10 times higher efficiency compared to an EMICl-based SiC film s...

Boron-doped graphene, synthesized by annealing a mixture of graphite oxide and B2O3, has shown a high conversion efficiency of 6.73% as a counter electrode (CE) for dye-sensitized solar cells, which is better than the Pt CE.

A novel ion selective PVC membrane electrode for determination of propranolol is developed. Silicotungstic acid is used as the counter ion and diisononyl phthalate (DNP) used as the plastizer. The electrode exhibits excellent potential response properties, showing a Nernstian response in the concentration of 3.0 × 10–6 ~ 2.6 × 10–2 M with the slope of 54.7 mV per decade, shorter conditioning ti...

A micro glucose sensor consisting of an interdigitated array gold microelectrode was developed. The interdigitated array structure, which has 10 microns band width and 10 microns band gap, was fabricated in a small region (2.5 x 5 mm2) on a quartz substrate. Glucose oxidase was chemically fixed onto the electrode surface through self-assembled monolayer of 11-mercaptoundecanoic acid; ferrocenea...
