A multielectrode setup for protein OFFGEL electrophoresis that significantly improves protein separation efficiency has been developed. Here, the electric field is applied by segments between seven electrodes connected in series to six independent power supplies. The aim of this strategy is to distribute evenly the electric field along the multiwell system, and as a consequence to enhance elect...

In order to calculate ion currents through solid-state nanopore transistors realistically, we propose a computational model based on the Poisson-Nernst-Plank equation. In the present model, we determine the surface charge density locally on the nanopore by imposing consistency between the ion distribution and the chemical reaction at the surface. The model can consider a non-uniform influence b...

Pressure, Electrode Potential, Reaction Volumes Pressure dependence of the electrode potentials for various M3+/2+ couples (M = Fe, Co, and Ni with o-phenanthroline, bipyridine, terpyridine, 1,4,7-triazacyclononane, and 1,4,7-trithiacyclononane) was measured by cyclic voltammetry in aqueous solution vs. a Ag/AgCl reference electrode. The reaction volume of the Ag/AgCl reference electrode was es...

Conformal mapping has been applied mostly to harmonic functions, i.e. solutions of Laplace’s equation. In this paper, it is noted that some other equations are also conformally invariant and thus equally well suited for conformal mapping in two dimensions. In physics, these include steady states of various nonlinear diffusion equations, the advection-diffusion equations for potential flows, and...

Granule cells were dissociated from rat cerebella with a procedure that yields a 98% pure cell population. Potassium currents in these cells were studied using the patch-clamp technique. Depolarizing pulses of 10 mV step and 100 ms duration from a holding potential of -80 mV elicited two different potassium outward currents: a transient, low-voltage activated component and a long lasting, high-...

In this article we study a system of nonlinear PDEs modelling the electrokinetics nematic electrolyte material consisting various ions species contained in liquid crystal. style='text-indent:20px;'>The evolution is described by coupling Nernst-Planck for concentrations with Maxwell's equation electrostatics governing electrostatic potential, Navier-Stokes velocity f...

The scaling behaviour for the rectification of bipolar nanopores is studied using Nernst-Planck equation coupled to Local Equilibrium Monte Carlo method. nanopore's wall carries ? and ?? surface charge densities in its two half regions axially. Scaling means that device function (rectification) depends on system parameters (pore length, H, pore radius, R, concentration, c, voltage, U, density, ...

We consider the Nernst effect in the normal state of the underdoped cuprate superconductors, where recent quantum oscillation experiments have indicated the existence of Fermi surface pockets and quasiparticle ambipolarity in the excitation spectrum. Using an ambipolar d-density-wave model for the pseudogap, we predict a peak in the Nernst coefficient with decreasing temperature below the pseud...

in this work, the results concerning to the mean activity coefficient measurements for nacl in the (glycerol + water) system using the potentiometric method are reported. the potentiometric measurements were performed on the galvanic cells without liquid junction of the type: ag|agcl|nacl (m), glycerol (wt%), h2o (1 - wt)%|na-ise, in various mixed solvent systems containing 0, 5, 10, 20 and 30 ...

High energy gain in inertial fusion schemes requires the propagation of a thermonuclear burn wave from hot to cold fuel. We consider problem when magnetic field is orthogonal wave. Using an extended-MHD model with magnetized $\alpha$ transport equation we find that can reduce rate by suppressing electron thermal conduction and particle flux. Magnetic during subject competing effects: be advecte...
