Collective motions on the picosecond time scale as a function of hydration level in hectorite clays.
The interaction of water with the surfaces of clay minerals has large effects, from the nano-scale to the meter-scale. The uptake of water into the interlayer spaces of smectites results in increased volume of the crystals; the collective motions of interlayer water may act additively to cause significant energy transmission. The collective motions of water under confinement, as for example in the interlayer spaces of clays, is thought to be anisotropic with respect to the crystal dimensions. We propose to analyze the collective motions of water in the smectite hectorite to gain a better understanding of the different conditions in which collective water motions occur in clays.
