چکیده

Magnetotransport measurements performed on several well-characterized highly oriented pyrolitic graphite and single crystalline Kish graphite samples reveal a reentrant metallic behavior in the basal-plane resistance at high magnetic fields, when only the lowest Landau levels are occupied. The results suggest that the quantum Hall effect and Landau-level-quantization-induced superconducting correlations are relevant to understand the metalliclike state(s) in graphite in the quantum limit.

Voltammetric Behavior and Determination of Trace Amounts of Omeprazole Using an Edge-plane Pyrolytic Graphite Electrode

The voltammetric performance of edge-plane pyrolytic graphite (EPG) electrode via adsorptive stripping voltammetry was investigated for study of the electrochemical behavior of omeprazole (OMZ) in aqueous solution. The results revealed that the oxidation of OMZ is an irreversible pH-dependent process that proceeds with the transfer of one electron and one proton in an adsorption-controlled mech...

Electrochemical Behavior of 2-Aminothiazole at Poly Glycine Modified Pencil Graphite Electrode

Electro analysis of 2-Aminothiazole (2-AT) by a low cost poly Glycine modified Pencil Graphite Electrode (poly Gly/PGE) was studied using of cyclic voltammetric (CV) and differential pulse voltammetric (DPV) techniques. The optimal experimental conditions to determine 2-AT was setup by the variation of the current with scan rate, concentration and pH. Electrochemical performance of the 2-AT at ...
