TLDR
In this article, the theoretical background for the electrokinetics in rocks and in porous media is described in a special issue of the International Journal of Geophysics (IJG).Abstract:
We describe in this paper the theoretical background for the electrokinetics in rocks and
in porous media, to be included in the special issue “Electrokinetics in Earth Sciences” of International Journal of Geophysics. We describe the methodology used for self-potential (SP) and for seismoelectromagnetic measurements, for both field and laboratory experiments and for modelling. We give a large bibliography on the studies performed in hydrology to detect at distance the water flow, to deduce the thickness of the aquifer and to predict the hydraulic conductivity. The observation of SP has also been proposed to detect fractures in boreholes, to follow the hydraulic fracturing, and to predict the earthquakes. Moreover, we detail the studies on geothermal applications.read more

Enhanced Transport into and out of Dead-End Pores
TL;DR: It is shown that chemically driven convective flows leading to transport in and out of dead-end pores can occur by the phenomenon of "transient diffusioosmosis", which depends on the presence of an in situ-generated transient ion gradient and the intrinsic charge on the pore wall.

TL;DR: In this paper, the basic electrical theory of geomaterials is set out together with sufficient experimental and modeling results to show what controls their electrical properties, including steady-state and frequency-dependent electrical transport and polarization.

Seismoelectric wave propagation numerical modelling in partially saturated materials
Sheldon Warden,Stéphane Garambois,Laurence Jouniaux,Daniel Brito,Pascal Sailhac,Clarisse Bordes +5 more
TL;DR: In this paper, an extension of Pride's equations aiming to take into account partially saturated materials, in the case of a water-air mixture, was incorporated into an existing seismoelectric wave propagation modeling code, originally designed for stratified saturated media.

A review on electrokinetically induced seismo-electrics, electro-seismics, and seismo-magnetics for Earth sciences
TL;DR: In this article, the authors describe the theoretical background of the seismo-electromagnetic method (SEM) and the role of some key parameters and detail recent studies on SEM, through theoretical and numerical developments, and through field and laboratory observations, to show that this method can bring advantages compared to classical geophysical methods.

Physical chemistry of surfaces
TL;DR: In this paper, the authors discuss the nature and properties of liquid interfaces, including the formation of a new phase, nucleation and crystal growth, and the contact angle of surfaces of solids.

Reciprocal Relations in Irreversible Processes. II.
TL;DR: In this article, a general reciprocal relation applicable to transport processes such as the conduction of heat and electricity, and diffusion, is derived from the assumption of microscopic reversibility, and certain average products of fluctuations are considered.
