III. On unequal electric conduction-resistance at cathodes [PDF]
Proceedings of the Royal Society of London, 1884 During some experiments which I have been making on the unequal resistance to the deposition of a metal upon cathodes of different metals in the same solution by the same current (see “Some New Phenomena of Electrolysis”), I have been led to investigate the resistance of cathodes of different metals to the passage of the current into them. I have found

Influence of Processing Parameters on the Conduct of Electrical Resistance Sintering of Iron Powders [PDF]
Metals, 2020 The influence of the applied pressure and electrical parameters on the macrostructure of specimens consolidated by the medium-frequency electrical resistance sintering technique (MF-ERS) is analysed in this work. This technique is based on the application of pressure to a mass of conductive powder that, simultaneously, is being crossed by a high ...

Effect of Chloride on Electrical Resistivity in Carbonated and Non-Carbonated Concrete
Applied Sciences, 2020 The resistivity of a concrete structure exposed to chloride ions indicates the risk of early corrosion damage, because a low resistivity is related to rapid chloride penetration and to a high corrosion rate. Concrete resistivity is a geometry-independent
