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.

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.

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.

Sensing moiteies may be covalently attached to glassy carbon by reduction of functionalised diazonium salts [1,2]. The attachment of glucose oxidase with a cinnamic acid linker provides an example of simple tethering using this technique. An electrode formed in this way exhibits little susceptibility to interference from ascorbic acid and 4 ...

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 ...

Graphitization of carbon fibre/ glassy carbon composites
Carbon, 1974Abstract Carbon fibre/glassy carbon composites were prepared by aligning unidirectionally in furfuryl alcohol condensate the PAN-based carbon fibres treated at different temperatures and with different degrees of stretching. The graphitization of the composites was found to start at the boundary between the fibres and glassy carbon matrix, and to ...

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.

Ion bombardment of glassy carbon
Vacuum, 2018Abstract Glassy carbon has applications in the storage of high level nuclear waste. Irradiation of glassy carbon are thus of importance to investigate. The paper reviews some aspects for ion bombardment. Glassy carbon is categorised as an amorphous material with graphitic crystallites. Glassy carbon has a much lower density than graphite. It has been

Switching phenomena in glassy carbon
Carbon, 1973Abstract Reversible switching effect was studied in carbonized polyfurfuryl-alcohol resin. Switching appears after heattreatment at a temperature of 300°C. The maximum temperature range for both heattreatment and measurements at elevated temperature was limited by melting of aluminum electrodes (659·7°C).
