Modeling streaming potential in porous and fractured media, description and benefits of the effective excess charge density approach
(Springer, 2020)
Self-potential signals can be generated by different sources and can be decomposed in various contributions. Streming potential is the contribution due to the water flux in the subsurface and is of particular interest in ...
An analytical effective excess charge density model to predict the streaming potential generated by unsaturated flow
(Wiley Blackwell Publishing, Inc, 2019-01)
The self-potential (SP) method is a passive geophysical method that relies on the measurement of naturally occurring electrical field. One of the contributions to the SP signal is the streaming potential, which is of ...
An effective excess charge model to describe hysteresis effects on streaming potential
(Elsevier Science, 2020-09)
Streaming potentials are produced by the coupling between the water flow and the electrical current generated by the drag of electrical charges within the pore water of the media. This electrokinetic coupling is strongly ...
Ordering of oxygen vacancies and excess charge localization in bulk ceria: A DFT+U study
(American Physical Society, 2014-09)
The importance of ceria (CeO2) in many applications originates from the ease of oxygen vacancy formation and healing. The ordering of vacancies and the whereabouts of the excess charge in bulk CeO2 are of no less significance ...
