Fast and Versatile Functionalization of Glassy Carbon
Langmuir, 2022A rapid procedure for the functionalization of glassy carbon surfaces (GCSs) is disclosed. A three-step sequence of bromomethylation, azide displacement, and copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) allows ethynylated molecules to be attached covalently to the carbon surface through a methylene functional group.

Microderivatization of Anodized Glassy Carbon
Analytical Chemistry, 1996Microelectrodes have been used to modify locally the electrochemical activity on glassy carbon electrodes. Glassy carbon was electrochemically oxidized to form an oxide layer which is inhibitory toward certain electron-transfer reactions. Activity was restored through the application of hydroxide, which was generated electrochemically at the tip of a ...

The Structure of Glassy Carbon
Japanese Journal of Applied Physics, 1986The structure of a glassy carbon made by Tokai Electrode Company has been studied by analyzing X-ray diffraction patterns from six types of sample subjected to different heat-treatments at temperatures from 700°C to 3,000°C. The diffraction intensity of Ag K α 1

From glassy carbon to mixed carbon
Science, 2017Materials Science Forging one of the world's hardest materials (diamond) from the same atomic carbon building blocks as one of its softest (graphite) has intrigued many a high school chemistry student. This dexterity of carbon originates from its ability to exist in two distinct bonded states, sp3 and sp2.

Diamagnetism of Glassy Carbons
Japanese Journal of Applied Physics, 1975The diamagnetic susceptibility (χ) in the range down to liquid nitrogen temperature has been measured of glassy carbons prepared by stepwise heat treatments between 800 and 3000°C. The observed |χ| increases with heat treatment temperature similarly to those for various nongraphitizing carbons.

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.

The electrochemical behavior of ceftriaxone was investigated on a carbon-nanotube-modified glassy carbon (GC-CNT) electrode in a phosphate buffer solution, pH = 7.40, and the results were compared with those obtained using the unmodified one [glassy carbon (GC) electrode].

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 ...

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.
