Electrical resistivity and thermal conductivity of UP1−xSx

Journal of Physics and Chemistry of Solids, 1976
Abstract UP, US, and their solid solutions of several compositions were prepared, and the electrical resistivities of these samples were measured from liquid nitrogen temperature to 1000 K and the thermal diffusivities from 300 to 1000 K. It was shown that the resistivity of UP 1− x S x at the paramagnetic region arose mainly from the scattering ...

Electrical contact resistance for a conductive Velcro system

Tribology International, 2014
Conductive Velcro fasteners are employed as a joining material for various types of connections due to their detachable properties, especially when an electrical connection is established. Due to microscopic actual contact spots between the fibers and hooks in the Velcro joints, a large electrical contact resistance is established that could cause heat

On the calculation of the electrical resistivity of conducting loose materials

Russian Metallurgy (Metally), 2011
A mathematical model has been built analytically to describe the dependence of the volume electrical resistivity of a loose material on its height and the external pressure. The electrical conductivity of the loose material is shown to be invariant with respect to the sizes of its fractions.

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.

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.
