Electrical properties of glassy-carbon electrodes
Medical & Biological Engineering & Computing, 1979Some electrical properties of the glassy-carbon electrode are presented. The electrode impedance is inversely proportional to the measurement frequency. The glassy-carbon electrode has pH sensitivity. The polarisation characteristic is given. To analyse these results, it is better that the adsorption of ions on the surface of the electrode is taken ...

Glassy carbon ceramic composite electrodes
Analytica Chimica Acta, 2006A new carbon composite electrode material, based on dispersing glassy carbon (GC) microparticles into methyltrimethoxysilane-derived sol, is described in the present paper. The resulting glassy carbon ceramic composite electrodes (GCCEs) combine the electrochemical properties of GC with the advantages of composite electrodes, and thus offer high ...

The electrochemical behavior of epinephrine at activated glassy carbon electrode and carbon nanotube-coated glassy carbon electrode was studied. Epinephrine could exhibit an anodic peak at about 0.2 V (vs. SCE) at bare glassy carbon electrode, but it was very small. However, when the electrode was activated at certain potential (i. e.

Vertically Aligned Carbon Nanotube Electrodes Directly Grown on a Glassy Carbon Electrode
ACS Nano, 2011Three-dimensional microelectrodes were fabricated using glassy carbon electrodes combined with vertically aligned carbon nanotubes (VACNTs). VACNTs were grown on various conducting electrode patterns including a carbon electrode fabricated by pyrolysis of a negative photoresist, with plasma-enhanced chemical vapor deposition using a bilayer Fe/Al ...

Amperometric Glucose Biosensors Based on Glassy Carbon and SWCNT‐Modified Glassy Carbon Electrodes
Electroanalysis, 2007AbstractDifferent carbonaceous materials, such as single‐walled carbon nanotubes (SWCNTs) and glassy carbon submitted to an electrochemical activation at +1.80 V (vs. SCE) for 900 s, have been used with the aim of comparing their performances in the development of enzyme electrodes.

Mercury nucleation on glassy carbon electrodes
Analytica Chimica Acta, 1997Abstract The amount of mercury, deposited on a glassy carbon electrode at various potentials during the first 200 ms of electrolysis, has been determined by constant current coulometric stripping potentiometry. Eight microliter samples, containing approximately 4 M chloride, were placed on top of a combined glassy carbon, Ag counter and Ag AgCl

Electrochemical studies on glassy carbon electrodes
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1973Summary Rate constant measurements for charge transfer processes at various electrodes show the general sequence k s (Pt)> k s (glassy carbon)> k s (wax-impregnated graphite) > k s (carbon paste). Maximum rates on glassy carbon electrodes have been observed after treatment with chromic acid, except for the reduction of iodate ion, where ...

Direct electrochemistry of catalase on glassy carbon electrodes
Bioelectrochemistry, 2002Catalase was investigated as a possible catalyst of the electrochemical reduction of oxygen on glassy carbon electrodes. The presence of catalase dissolved in solution only provoked a moderate current increase, which was fully explained by the catalase-catalysed disproportionation of hydrogen peroxide (Scheme I).
