Corrosion resistance and electrical conductivity of plasma nitrided titanium

International Journal of Hydrogen Energy, 2021
Abstract The continuous and dense Ti–N compound layers with a thickness ranging from 0.7 to 2.1 μm were formed on the titanium by plasma nitriding at 700 °C for different times with hollow cathode discharge assistance. Scanning electron microscope (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) were used to characterize the ...

Determination of the electrical conductivity of heat-resistant concretes

Refractories, 1994
The problem of the electrical conductivity of heat-resistant concretes and bonding agents is considered and a method for determining this parameter is suggested. In addition to the thermal resistivity, the electric conductivity is a factor affecting the lifetime of lining materials for high-temperature devices.

SURFACE-INDUCED ELECTRICAL RESISTIVITY OF CONDUCTING THIN FILMS [PDF]

Surface Review and Letters, 2005
A quantum approach is proposed to calculate the surface-induced electrical resistivity of metallic and semiconducting thin films when several subbands of Fermi participate of the electronic transport. The application of this approach to explain the experimental resistivity data of Pt and Au thin films is briefly reported.

Electrical properties of conductive and resistive ZnSe layers

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2008
The authors have investigated the electrical properties for one typical set of Al-doped ZnSe layers: one is conductive (type I) and the other is resistive (type II). The two types of ZnSe:Al layers are grown on different substrates by molecular-beam epitaxy under the same conditions: type I is on a 15° tilted (001) GaAs substrate and type II is on an ...

The Effect of Electrical Conductivity on Pore Resistance and Electroporation

Volume 13: Nano-Manufacturing Technology; and Micro and Nano Systems, Parts A and B, 2008
Electroporation refers to the permeabilization of the cell membrane with one or multiple electric pulses. The reversible form of electroporation is widely applied for drug delivery, gene and cancer therapy, and stem cell research, among others; the irreversible form of electroporation is being explored for cancer treatment in a drug-free manner.

Electrical Noise in a TES as a Resistively Shunted Conducting Junction

Journal of Low Temperature Physics, 2012
We present results of the analysis of electrical noise in a transition edge sensor (TES) as a resistively shunted conducting junction (the RSJ model). We derive an expression for the spectral density of voltage fluctuations taking into account weak superconductivity of a TES.

Micromechanical approach for electrical resistivity and conductivity of sandstone

Journal of Applied Geophysics, 2014
Abstract The objective of this work is to employ the micromechanical approach for the modeling of the electrical resistivity and of the conductivity of sandstone. This type of rock is considered as a mixture of solid mineral and porous space filled fully or partially by conductive water.

Correlation of Thermal Conductivity and Electrical Resistivity of Carbonates

Proceedings, 2012
Thermal properties are of interest for geothermal studies. A problem is to obtain thermal conductivity from in-situ conditions. One way to solve this problem is the application of relationships to other geophysical rock properties especially for carbonates.

CONDUCTION AND RESISTANCE

2010
241.] I f by means of an electrometer we determine the electric potential at different points of a circuit in which a constant electric current is maintained, we shall find that in any portion of the circuit consisting of a single metal of uniform temperature throughout, the potential at any point exceeds that at any other point farther on in the ...

Electrical resistivity of conducting particles in an insulating matrix

Journal of Applied Physics, 1972
When conducting particles are added to a nonconducting matrix, conductivity increases abruptly at a critical concentration. The theory of infinite chains is used to predict the variation of conductivity with particle concentration. Factors which determine the critical concentration are discussed.
