  In this paper, the uniaxial strain effect on the electronic properties of (6,6) finite armchair carbon nanotube was investigated by using the Green function technique and Landure-Buttiker formula. It was found that, in (6,6) finite carbon nanotube with 3q and 3q+1 length, where q is a certain integer, the current was induced by the application of a suitable tensile strain and compressive stra...

Inhibitory effect of extracts from three date varieties namely khalt (kha), Lassiane (La) and Tadmamt (Td)), and the mixture of date varieties as environmentally friendly corrosion inhibitor for carbon steel in 1M HCl is studied by means of electrochemical tests such as electrochemical impedance spectroscopy (EIS), and Tafel polarization. It's been obtained that in 1.0 M HCl solution the date e...
