Fluid displacive embedding

Fluid displacive embedding Displacing one fluid by another, usually water by acetone, and then adding low viscosity epoxy resin, which is then cured to produce a solid resin-embedded sample. 

Fluid displacive drying and resin-embedding of wet sediments... 

Fluid displacive resin-embedding of wet sediment is a passive procedure, samples are never physically dry and the fabric is supported by fluid throughout. Chemical dehydration prevents the cracking (common in vacuum dried sediment), and the technique requires no specialized drying, or resin-impregnating equipment. Water-saturated samples are more successfully embedded using fluid replacement than those which are partially dry. 

Fluid displacive low viscosity resin embedding technique... 

Ferroelectric fluid phases have also been observed in simulations of disk-shaped particles with embedded dipole moments along the symmetry axis [ 147,148] (see Sect. 4) and in a dipolar hard sphere model carrying two parallel dipole moments displaced equally from the sphere centre [ 149]. In the latter model antiferroelectric arrangement of the particles is, however, equally preferred at sufficiently large separations (0.3a) of the two dipole moments. 

This technique is pretty new and has already been successfully applied to measure the viscoelastic properties of gels based on the gelators. The principle of this technique is based on the tracking of submicrometer tracers embedded within a solution. The mean-squared displacement of the tracers is given by (Ar (r)) a t , where a = 1 for liquids and o < 1 for viscoelastic fluids. It appears that (Ar (r)) is also related to the viscoelastic modules through the generalized Stokes-Einstein relation ...
