Through this technique optically isotropic fluid
microstructure, dispersed with the dimension generally in the 1-150 nm range and formed spontaneous mixture from two immiscible liquids.
25] the medium is an isotropic fluid
with speed 1, but outside of this region we have an anisotropic solid represented by the 2 x 2 matrix with 2 on the diagonal and 1 on the off-diagonal.
Therefore, a deep understanding of the interfacial dynamics is needed, not only in isotropic fluids
with Newtonian flow properties, but also in anisotropic systems and in fluids that exhibit non-Newtonian behaviour.
