Abstract

Ball milling was utilized to prepare nano compounds of tantalum pentoxide and cobalt sulphate that used a Retsch MM2000 apparatus and three stainless steel balls with diameters of 12 mm. The new filled nano composite working electrode was created by combining nano tantalum petoxide to multicarbon nanotubes and carbon in a specific ratio, and the final nano paste was applied to the tip of a glassy carbon electrode. Cyclic voltammetry was used to investigate the redox reaction of NCS alone and in combination with FA in 0.1M KBr at two different temperatures (292.15&297.15)K. At the two temperatures used, various solvation and kinetic parameters were evaluated and discussed. In addition, in order to study complexation, various thermodynamic data, including stability constants, complexation Gibbs free energies, enthalpies, and entropies, were measured for the communication of NCS to FA. Their values were then discussed. At last, through using Molecular Operating Environment (MOE) and human Myosin 9b RhoGAP domain crystalline phase at 2.2 Angstrom, a molecular modelling study was conducted to explain the studied anticancer activity of FA (5C5S).
