Electrical properties of Sb and Cr-doped PbZrO3-PbTiO3-PbMg1/3Nb2/3O3 ceramics [PDF]

open access: yes, 2003
The pyroelectric, dielectric and DC resistive properties of Sb and Cr-doped ceramics with a base composition of Pb(Mg1/3Nb2/3)0.025(Zr0.825Ti0.175)0.975O3 have been studied. Sb doping has been shown to produce a linear reduction in Curie temperature (TC=−

Cementation effect evaluation of MICP sand solidification via electrical resistivity

open access: yesYantu gongcheng xuebao, 2021
There is no simple and feasible method to evaluate the on-site cementation effect of microbially induced calcium carbonate precipitation (MICP). Therefore, this study uses a convenient and non-destructive electrical resistivity method to evaluate the ...

Area Selective Deposition of Metals from the Electrical Resistivity of the Substrate [PDF]

open access: yes, 2021
Area selective deposition (ASD) of films only on desired areas of the substrate opens for less complex fabrication of nanoscaled electronics. We show that a newly developed CVD method, where plasma electrons are used as the reducing agent in deposition ...

Effect of Chloride on Electrical Resistivity in Carbonated and Non-Carbonated Concrete

open access: yesApplied 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
