In hydrothermal systems associated with volcanic areas, the flow of groundwater generates
an electrical current of electrokinetic nature, the so-called streaming current. This current is …

Nanoporous media consist of homogeneous or heterogeneous porous material in which a
significant part of the pore size distribution lies in the nanometer range. Clayey rocks …

The surface conductivity of porous rocks has two contributions: the first is associated with the
diffuse layer coating the grains and is frequency-independent as long as the diffuse layer is …

Low-frequency geoelectrical methods include mainly self-potential, resistivity, and induced
polarization techniques, which have potential in many environmental and hydrogeological …

Porous electrodes instead of flat electrodes are widely used in electrochemical systems to
boost storage capacities for ions and electrons, to improve the transport of mass and charge …

The self-potential method enables non-intrusive assessment and imaging of disturbances in
electrical currents of conductive subsurface materials. It has an increasing number of …

The low-frequency conductivity response of water-saturated packs of glass beads reflects a
combination of two processes. One process corresponds to the polarization of the …

We consider a charged porous material that is saturated by two fluid phases that are
immiscible and continuous on the scale of a representative elementary volume. The wetting …

Water‐saturated clay‐rich media exhibit low‐frequency (1 Hz to 1 MHz) effective conductivity
and effective permittivity dispersions that are the consequence of both the polarization of the …

Natural electric currents running through marine sediments have recently been found to
couple oxygen reduction at the surface to sulfide oxidation in deeper anoxic layers. Here we …
