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...

متن کاملExtinction of ferromagnetism in highly ordered pyrolytic graphite by annealing
We report that the ferromagnetism of highly ordered pyrolytic graphite (HOPG) samples as measured by hysteretic magnetization loops can be diminished and eventually extinguished with sufficiently long high vacuum anneals at temperatures on the order of 2300 !C. Concomitant with the extinction of ferromagnetism, we observe an annealinduced increase in grain size (accompanied by possible edge rec...
متن کاملEdge plane pyrolytic graphite electrodes in electroanalysis: an overview.
The recent development, behavior and scope of edge plane pyrolytic graphite electrodes in electroanalysis are overviewed. Similarities to, and advantages, over multi-walled CNT modified electrodes are noted and the wide scope of applications, ranging through gas sensing, stripping voltammetry and biosensing, illustrated.
متن کاملUFM observation of lattice defects in highly oriented pyrolytic graphite
Ultrasonic force microscopy (UFM) can be used to image the distribution of elastic modulus up to several tens of GPa, which is not possible by the force modulation mode using a soft cantilever of spring constant less than 1 N m‘. It was shown that by careful design of a piezoelectric transducer, together with a sample with small friction force, deflection vibration of the cantilever without tor...
