Six methods have given squid axoplasm resistivities of from 1.0 to 6.9 times seawater (X SW), so another was tried. A 100-mum platinized electrode was to be inserted from each end of an axion in iso-osmotic sucrose and impedance between them measured vs. separation. But observations that the resistance of axons in sucrose increased steadily ruled this out. Axoplasm from two or three axons was t...

The effect of surface phonon scattering on the electrical resistivity has been observed in Co/Ni superlattices, with reproducible film microstructure, independent of the film thickness. The temperaturedependent part of the resistivity increases rapidly with decreasing film thickness for films thinner than the electronic mean free path. The resistivity shows a universal behavior well characteriz...

We report here pressure dependence of the electrical resistivity of natural kalsilite (K0.998Na0.002Al0.998Fe0.002SiO4) from a granulite facies terrain in southern India. The electrical resistivity of kalsilite was measured with four probe technique up to 7.5 GPa at room temperature. The electrical resistivity decreases continuously with the increase of pressure up to 3.7 GPa, where there is a ...

This article consists of geoelectrical resistivity data sets for thirty (30) vertical electrical sounding (VES) and four (4) traverses of 2D electrical resistivity imaging (ERI) collected within Iyesi, Ota, southwestern Nigeria for about five (5) weeks between December, 2016 and January, 2017 using an ABEM Terrameter (SAS1000/4000). The observed apparent resistivity data sets for the VES were p...

A three-dimensional particle-in-cell simulation in a large system demonstrates that a kink mode significantly contributes to a fast reconnection by providing magnetic dissipation through anomalous resistivity. The anomalous resistivity is generated due to the electron heating in the thin electron current sheet. It is interesting that, although the kink mode broadens the width of the current she...

The Plasma resistivity has been measured in the edge plasma of IR-T1 tokamak. To achive the edge plasma properties ( Te and ne ) using I-V characteristics of movable single langmuir probe. Density and temperature of electron, respectively ne and Te, are measured simultaneously for calculating the radial profile of parallel and vertical resistivity. As temperature of plasma raised, resistivity d...

This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system w...

sn02 nanowires with diameters of 30 — 200 nm have been synthesized by using carbothermalprocess via a thick film of tin dioxide and carbon powder precursor. the nanowires werecharacterized by x-ray power diffraction (xrd), scanning electron microscopy (sem),transmission electron microscopy (tem) and selected area electron diffraction (saed).the gas sensing characteristic of nanowires toward eth...

Time-lapse resistivity measurements and groundwater geochemistry were used to study salinity effect on groundwater aquifer at the ex-promontory-land of Carey Island in Malaysia. Resistivity was measured by ABEM Terrameter SAS4000 and ES10-64 electrode selector. Relationship between earth resistivity and total dissolved solids (TDS) was derived, and with resistivity images, used to identify wate...

Since the last few decades, electrical methods have been widely used in geophysical surveying to obtain high-resolution information about subsurface conditions. Resistivity is an important parameter in judging the ground properties, especially detecting buried objects of anomalous conductivity. Electrical DC resistivity sounding is the commonly used technique to obtain the apparent 2-D resistiv...
