Bi-directional unsteady flow of nanomaterial has been explored in the existence of Cattaneo-Christov double diffusion. Brownian motion, thermophoresis and heat sources namely PST (prescribed surface temperature) and PHF (prescribed heat flux) are included. The obtained nonlinear systems are computationally solved by employing Keller box method. Graphs have been created for temperature and concentration fields for distinct amounts of involved parameters. Tables have been generated and discussed for skin friction, heat and mass transfer rates. It is assessed that temperature and concentration are reducing fields of thermal and relaxation factors for prescribed heat flux. Obtained effects are linked with the formerly published results and found favorable agreement. Keywords: Nanomaterial, Unsteady stretching, Cattaneo-Christov double diffusion, Keller box method
