The total electric resistance R is theoretically linearly increasing function of the conductive wire length L because the electric conductivity K or electric resistivity r is independent on L. It was found out that dependence of electric resistance R on L is highly nonlinear for yarns containing the conductive metal fibers. The main aim of this paper is creation of the simple mechanistic model ...

Electronic transport through a quantum wire sandwiched between two metallic electrodes and coupled to a quantum ring, threaded by a magnetic flux φ, is studied. An analytic approach for the electron transport through the bridge system is presented based on the tight-binding model. The transport properties are discussed in three aspects: (a) presence of an external magnetic filed, (b) strength o...

A top-to-bottom joined system consisting of a silver nanowire and nanospheres was fabricated by embedding silver nanospheres on a glass or silicon substrate on which 3-aminothiophenol as an analyte molecule was adsorbed, and then placing silver nanowires on the substrate to make gap sites between a nanowire and nanospheres. In the far-field Raman measurements, the sphere under the wire exhibite...

AbstmctThe stationary electric field and current distribution in a ring shaped wire subject to both parallel and perpendicular applied magnetic fields is calculated. The time derivative of the parallel field is limited for the centre of the wire to be unsaturated. The transient response of an infinitely long wire due to a parallel applied magnetic field BA shows that BA itself is limited for th...

Nonconventional machining technologies have been found viable to manufacture various products from a wide range of engineering materials. Wire electric discharge (WEDM), also known as Wire-EDM, is one the important thermal type nonconventional technologies. Wire-EDM being preferably used by manufacturers produce biomedical devices including bio and dental implants. This paper presents an overvi...

A spin-boson model based on local pseudo-spins acting in the electronic occupation number space is suggested and used to describe the thermally activated interelectrode current through a molecular wire. Utilizing the density matrix technique a unified description is achieved of all those kinetic processes which contribute to the inelastic current formation. These processes cover a specific supe...

The direct measurement of the plasma potential poses a major challenge to plasma diagnostic, and the sole tools for localized measurement of this parameter are certain forms of electric probes. For many decades emissive probes have been used in laboratory plasmas for a direct determination of the plasma potential Φpl. Only during the last years emissive probes have been applied for the first ti...

[1] A total of three negative rocket-triggered lightning flashes without return strokes (two from 1997 and one from 1993) are analyzed in this paper in order to study the processes associated with the disintegration of the triggering wire and its replacement by an airplasma channel. It appears that the gap resulting from the vaporization of the triggering wire by the upward-positive leader curr...

Liquid pumping can occur along the outer surface of an electrode under a DC electric field. For biological applications, a better understanding of the ionic solution pumping mechanism is required. Here, we fabricated CNT wire electrodes (CWEs) and tungsten wire electrodes (TWEs) of various diameters to assess an ionic solution pumping. A DC electric field created by a bias of several volts pump...

1 INTRODUCTION Electric power utilities have sustained significant damage from lightning. The occurrence of line faults is one result of lightning damage. To prevent it, power utilities adopt various measures of protection from lightning. Transmission line overhead ground wires greatly contribute to a decrease in the number of line faults by preventing direct hits to the power lines. Lightning ...
