چکیده
Electrical properties of carbon nanotube depend strongly on its lattice structure, which is specified by the chiral and translational vectors. Toroidal shape of nanotube admits various twisted structures along the axis direction. Kinematics for the conducting electrons, and the persistent currents in toroidal carbon nanotube are investigated theoretically. We show that waveform of the persistent currents exhibits a special character of the cylindrical lattice structure for twisted cases. We discuss possibilities that the twist changes the period of the current into one half of the flux quantum, and the current flows without any external magnetic field.

The electrochemical oxidation of sulfamethazine (SMZ) has been studied at a multi-walled carbon nanotubes modified glassy carbon electrode (MWCNT-GCE) by cyclic voltammetry. This modified electrode (MWCNT-GCE) exhibited excellent electrocatalytic behavior toward the oxidation of SMZ as evidenced by the enhancement of the oxidation peak current and the shift in the anodic potential to less posit...
