CONDUCTIVE GEOPHYSICAL ANOMALIES ASSOCIATED WITH PETROLEUM HYDROCARBON BIODEGRADATION PROCESS IN A NON-SATURATED ZONE
(Helmholtz Centre Environmental Research-ufz, 2008-01-01)
Geophysical surveys using eletroresistivity methods and hidrochemical analyses were applied aiming the characterization of geoelectrical signatures in hydrocarbon contaminated sites located in an industrial site in Sao ...
Asymmetrical penetration of microwave in a conducting media and determination of microwave conductivity for very thin samples using electron spin resonance
(Elsevier B.V., 2001-05-01)
Dyson's theory of conduction electron spin resonance (CESR) has been used in the limit d less than or equal to delta (d being the thickness of the sample and delta the skin depth of the microwave field) to obtain the ...
Electrical characterization of lead zirconate titanate prepared by organic solution route
(Elsevier B.V., 2001-01-01)
Two series of lead zirconate titanate (PZT) ceramics with composition Zr/Ti approximate to 53/47 have been prepared by the organic solution route. The effects on the electrical properties of calcination temperature in one ...

Electrical, mechanical, and thermal analysis of natural rubber/polyaniline-DBSA composite
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2014-08-01)
A composite of natural rubber (NR) with polyaniline (PANI) was obtained by mixing an aqueous dispersion of dodecylbenzenesulfonic acid (DBSA)-doped PANI with NR latex in different concentrations. Films were obtained by the ...
Estimation of hydraulic parameters of shaly sandstone aquifers from geoelectrical measurements
(Journal of Hydrology, 2000)
Electrical and hydraulic conductivities of shaly sandstones are described using a capillary approach for a granular, clay bearing material. The clays are assumed to occur as shale shells uniformly coating the insulated ...

Influence of pH of Colloidal Suspension on the Electrical Conductivity of SnO2 thin Films Deposited Via Sol-Gel-Dip-Coating
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2011-01-01)
Tin dioxide (SnO2) thin films are deposited by the dip-coating technique from colloidal suspensions prepared with distinct pH through the sol-gel method. The decrease of the pH contributes to the destruction of an electrical ...
Quantum theory of the effect of grain boundaries on the electrical conductivity of thin films and wires
(Elsevier, 2015)
We calculate the electrical conductivity of a metallic sample under the effects of distributed impurities
and a random distribution of grain boundaries by means of a quantum mechanical procedure based on
Kubo formula. ...
