The thermal conductivity and electrical resistivity of rhenium
Journal of the Less Common Metals, 1963Abstract Values are presented and discussed for the thermal conductivity and electrical resistivity of a sample of rhenium. The temperature range covered is 80° to 500°K, for the thermal conductivity and 1.85° to 1,660°K for the electrical resistivity.

Resistance heating using electrically conductive cements
Advances in Cement Research, 2004Steel fibre (8 μm diameter, 0·72 vol.%)-reinforced cement was found to be effective for resistance heating. A DC electrical power input of 5·6 W (7·1 V, 0·79 A) resulted in a maximum temperature of 60°C (initial temperature = 19°C) and a time of 6 min to reach half the maximum temperature. Efficiency of energy conversion increased with time of heating,

The thermal conductivity and electrical resistivity of indium
Philosophical Magazine, 1962Abstract Values for the thermal conductivity, electrical resistivity and Lorenz number of the metal indium are reported for the approximate temperature range -190° to 120°C. The Lorenz number no longer behaves anomalously and the value hitherto listed for the thermal conductivity of indium at normal temperatures is considered to be low by a factor of 3·

Electrical Resistance of Solder Joints on Conductive Ribbons
2020 43rd International Spring Seminar on Electronics Technology (ISSE), 2020The paper deals with high humidity and high temperature ageing reliability of joints soldered / glued by non-conductive adhesive (NCA) onto the conductive ribbon. The prepared samples were accelerated aged at $85 \, ^{\circ}\mathrm{C}$ temperature and 85 % RH for 1000 hours.

Electrical resistivity and thermal conductivity of UP1−xSx
Journal of Physics and Chemistry of Solids, 1976Abstract 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 Conductivity and Resistivity
1999A high resistivity is the same as a low conductivity and a low resistivity is the same as a high conductivity. This chapter discusses everything in terms of resistivity, with the understanding that conductivity can be obtained by taking the inverse of resistivity.

Estimation of the volume resistivity of electrically conductive composites
Polymer Composites, 1997AbstractThe modeling of the electrical conductivity of polymer composites reinforced with conductive fibers is investigated. Existing models generally can be divided into percolation theories and non‐percolation theories. The basis of the percolation theory is the fact that the conductivity of the composite increases dramatically at a certain fiber ...

Electrical resistivity and conductivity of greases: An initial study
Lubrication Science, 2002AbstractInvestigations of railway wagons fitted with rolling‐element bearings have shown damage to the bearings from the passage of electric current. This also occurs in railway wagons without an electric energy consumption of their own, because of residual currents from electric locomotives. This phenomenon gives rise to technical, financial, and even

Electrical contact resistance for a conductive Velcro system
Tribology International, 2014Conductive 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
