The interaction of water with a synthetic saponite clay sample, with a layer charge of 1 per
unit cell (0.165 C m-2), was investigated by following along water adsorption and desorption …

The structure of swelling clays consists of a framework composed of negatively charged clay
platelets and interlayer cations. Swelling clays present different behaviors as a function of …

The ac conductivity of a series of dehydrated alkali metal-exchanged (Li+, Na+, K+, Rb+,
and Cs+) montmorillonites has been measured at different temperatures, and the activation …

In this paper we present an analysis of the surface of an Algerian montmorillonite. We use
two classical methods and we develop two new methods of following the variation of the …

Dehydration enthalpy and dc conductivity obtained by means of thermogravimetric analysis
and complex impedance spectroscopy respectively on three alkaline-earth, ie Mg2+, Ca2+ …

A direct synthesis of Na-mordenite, characterized by Si/Al ratios ranged from 5.5 to 12,
without introducing any organic compounds, is reported. The effect of aluminium …

Dc conductivity of the whole series of homoionic alkali exchanged montmorillonites is
investigated by means of Complex Impedance Spectroscopy. Conductivity of the samples is …

The work presented here proposes a new interpretative method for thermally stimulated
depolarization current (TSDC) measurements. By applying the concept of electronegativity …

The design of a radioactive waste repository typically involves a multi-barrier system,
including the natural barrier system (NBS), ie, the host rock and its surrounding subsurface …

Nonlinear, dynamic coupling effects and the manifestation of stochastic resonance are
explored in the context of frictional geomaterials. The first experiment is designed to study a …
