Electrophoresis techniques are characterized by concentration disturbances (or waves) propagating under the effect of an electric field. These techniques are usually performed in microchannels where surface conduction through the electric double layer (EDL) at channel walls is negligible compared with bulk conduction. However, when electrophoresis techniques are integrated in nanochannels, shal...

The paper examines a well-known experimental property of increase of the magnetoresistance effect in a metal observed with a decrease of the metal temperature. This property is explained by the fact that magnetoresistance is a quantity proportional to the relaxation time of the electric conduction of the metal sample which is a parameter observed in the absence of the magnetic field. Since the ...

Enhanced AAIR7DDDR pacing (atrial-based Managed Ventricular Pacing [MVP]) is a novel pacing mode that facilitates intrinsic conduction whenever possible to mitigate the deleterious effects of prolonged duration right ventricular (RV) electric stimulation on left ventricular contractility. The following case illustrates uncommon ECG and hemodynamic consequences of this algorithm in a patient wit...

We investigate the nature of the superconducting current from the Maxwell’s displacement current. We argue that the conduction current density term of the Maxwell’s equations is physically untrue, and it should be eliminated from the equations. Essentially, both the superconducting current and conduction current are originated from the Maxwell’s displacement current characterizing the changes o...

In an attempt to improve the field emission (FE) characteristics of carbon nanotubes (CNTs), we have performed a first-principles study on MgOcoated CNTs. A MgO slab covering a CNT tip under a strong electric field shows dielectric screening behaviours with applied electric fields up to 0.3 V Å−1 and the effective dielectric constant approaches the bulk value within a few MgO layers. It is also...

Tunnelling effect is a possible mechanism to explain the apparent large electric conductivity and nonlinear electric behavior of graphene-reinforced nanocomposites with polymer matrix. In this work, a numerical modeling framework is proposed to evaluate the effective electric conductivity in polymer composites reinforced with graphene sheets, taking into account the electrical tunnelling effect...

We report the results of a theoretical study of graphene/BN/graphene and BN/graphene/BN trilayers using the van-der-Waals-corrected density functional theory in conjunction with the non-equilibrium Green's Function method. These trilayer systems formed from graphene and BN exhibit distinct stacking-dependent features in their ground state electronic structure and response to an applied electric...

Abstract The resistive switching (RS) mechanism of hybrid organic-inorganic perovskites has not been clearly understood until now. A switchable diode-like RS behavior in MAPbBr 3 single crystals using Au (or Pt) symmetric electrodes is reported. Both the high resistance state (HRS) and low (LRS) are electrode-area dependent light responsive. We propose an electric-field-driven inner p-n junctio...
