The electrorheology of suspensions consisting of Na-Fluorohectorite synthetic clay particles in silicon oil
Y. Méheust, K. P. S. Parmar, B. Schjelderupsen +1
Under application of an electric field greater than a triggering electric field kV/mm, suspensions obtained by dispersing particles of the synthetic clay fluoro-hect…
Packing and voids in electro-rheological structures of polarized clay particles
K. P. S. Parmar, Y. Meheust, J. O. Fossum +2
Oil suspensions of fluorohectorite clay particles exhibit a dramatic meso-structural ordering when submitted to a strong electric field. This is due to dipolar interaction between…
Electrorheological suspensions of laponite in oil: rheometry studies under steady shear
K. P. S. Parmar, Y. Meheust, J. O. Fossum
We have studied the effect of an external DC electric field (~kV/mm) on the rheological properties of colloidal suspensions consisting of aggregates of laponite particles in a sili…
Inferring orientation distributions in anisotropic powders of nano-layered crystallites from a single two-dimensional WAXS image
Yves Meheust, Kenneth Dahl Knudsen, Jon Otto Fossum
The wide-angle scattering of X-rays by anisotropic powders of nano-layered crystallites (nano-stacks) is addressed. Assuming that the orientation distribution probability function…
Using synchrotron X-ray scattering to study the diffusion of water in a weakly-hydrated clay sample
Y. Meheust, B. Sandnes, G. Lovoll +6
We study the diffusion of water in weakly-hydrated samples of the smectite clay Na-fluorohectorite. The quasi one-dimensional samples are dry compounds of nano-layered particles co…
Intercalation-enhanced electric polarization and chain formation of nano-layered particles
J. O. Fossum, Y. Meheust, K. P. S. Parmar +3
Microscopy observations show that suspensions of synthetic and natural nano-layered smectite clay particles submitted to a strong external electric field undergo a fast and extende…
