Shape sensitive crystallization in colloidal superball fluids

Some of these phases are consistent with the so-called. We show that colloidal silica superballs crystallize into canted phases in the presence of depletants.

A natural example of this phenomenon can be found in the gem opal where spheres of silica assume a close-packed locally periodic structure under moderate compression.

Colloids crystallization crystals fluids Abstract. Guiding the self-assembly of materials by controlling the shape of the individual particle constituents is a powerful approach to material design. We show that colloidal silica superballs crystallize into canted phases in the presence of depletants.

Some of these phases are consistent with the so-called Formula lattice that was. Uniform colloidal silica superballs crystallize into a variety of ordered phases when depletant objects induce attraction between the colloids. The differences in these entropy-driven self-assembled structures are driven by minute deviations of the particle shape and are uniquely determined by an interplay between the size of depletants and superballs.

Tuning this ratio allows to smooth the deviation in particle shape. Shape-sensitive crystallization in colloidal superball fluids. Laura Rossi Vishal Soni Douglas J.

In this work we have shown that colloidal silica superballs crystallize into a variety of ordered phases when depletant objects induce an attraction between the colloids. The differences in these entropically stabilized structures are driven by minute deviations of the particle shape and are uniquely determined by an interplay between the size of depletants and the fine structure of the superball shape. The use of depletant size to leverage fine features of the shape.

Re-entrant solidifcation in polymer-colloid mixtures as a consequence of competing en-tropic and enthalpic attractions. A colloidal crystal is an ordered array of colloid particles and fine grained materials analogous to a standard crystal whose repeating subunits are atoms or molecules. A natural example of this phenomenon can be found in the gem opal where spheres of silica assume a close-packed locally periodic structure under moderate compression.
