devices. Morphologies of the metal nanostructures should be taken into consideration to maximize the properties of the metal surface. In general, morphologies such as spheres (particles), [ 1d , 4 ] platelets (squares, triangles etc), [ 1c,e ] and vertically aligned pillars [ 5 ] have been systematically generated. Since the interface of the junction is often a 2D crystalline plane with high sy...

The problem of concentric pervious spheres carrying a fluid source at their centre and rotating slowly with different uniform angular velocities Ω1, Ω2 about a diameter has been studied. The analysis reveals that only azimuthal component of velocity exists, and the couple, rate of dissipated energy is found analytically in the present situation. The expression of couple on inner sphere rotating...

We develop a semianalytic formulation suitable for solving the Navier-Stokes equations governing the induced steady, axially symmetric motion of an incompressible viscous fluid confined in a wide gap between two differentially rotating concentric spheres. The method is valid for arbitrarily high Reynolds number and aids in the presentation of multiple steady-state flow patterns and their bifurc...
