Unsteady viscous two-dimensional magnetohydrodynamic micropolar flow, heat and mass transfer from an infinite vertical surface with Hall Ion-slip currents is investigated theoretically numerically. The simulation presented motivated by electro-conductive polymer (ECP) materials processing in which multiple electromagnetic effects arise. primitive boundary layer conservation equations are transf...

A trapped ion transported along a periodic potential is studied as a paradigmatic nanocontact frictional interface. The combination of the periodic corrugation potential and a harmonic trapping potential creates a one-dimensional energy landscape with multiple local minima, corresponding to multistable stick-slip friction. We measure the probabilities of slipping to the various minima for vario...

Because of its kinetic nature and computational advantages, the Lattice Boltzmann method (LBM) has been well accepted as a useful tool to simulate micro-scale flows. The slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. The most used slip boundary condition is the Maxwell slip model. The results of Maxwell slip model are affected by the ac...

The interstellar magnetic field strength and density are observed to be correlated, but there is a large dispersion in this relation. In particular, the magnetic field is often observed to be weaker than expected. It is usually assumed that the field is frozen into the gas except at very high density and low ionization fraction, in which case ion-neutral drift, or ambipolar diffusion, leads to ...

The importance of the slip flow over the no-slip condition is widely accepted in microscopic scaled domains with the direct impact on microfluidic and nanofluidic systems. The popular Navier Stoke’s (N-S) flow model is largely utilized with the slip flow phenomenon. In the present study, the finite integral transform scheme along with the shift of variables is implemented to solve the equation ...

Metal ion transport by DCT1, a member of the natural resistance-associated macrophage protein family, is driven by protons. The stoichiometry of the proton to metal ion is variable, and under optimal transport conditions, more than 10 protons are co-transported with a single metal ion. To understand this phenomenon better, we used site-directed mutagenesis of DCT1 and analyzed the mutants by co...

The influence of the texture of a hydrophobic surface on the electro-osmotic slip of the second kind and the electrokinetic instability near charge selective surfaces (permselective membranes, electrodes, or systems of microchannels and nanochannels) is investigated theoretically using a simple model based on the Rubinstein-Zaltzman approach. A simple formula is derived to evaluate the decrease...

A •nodel of mantle convection which generates plate tectonics requires strain rateor stress-dependent rheology in order to produce strong platelike flows with weak margins as well as strike-slip deformation and plate spin (i.e., toroidM motion). ttere, we exnploy a simple model of source-sink driven surface flow •o determine the form of such a theology that is appropriate for Earth's present-da...
