79. Pressure-induced interdigitation in bicellar mixtures containing anionic lipid

Invited Speaker / Conférencier invité

Phospholipid bilayer interdigitation can be induced by the application of hydrostatic pressure. Bilayers of anionic lipid are known to interdigitate at lower pressures than bilayers of corresponding lipids with zwitterionic headgroups. Dispersions of lipid mixtures with long and short chains, known as bicellar mixtures, can exist as small bilayered micelle disks at temperatures below the...

Very often the cholesteric liquid crystals are obtained by mixing a small quantity of chiral molecules in a nematic liquid crystal host. The homogeneous mixture is obtained by molecular diffusion, which takes place due to chaotic (thermal) motion of individual molecules. This process is temperature dependent. However, the breakdown of physical symmetry also affects dramatically the diffusion...

84. Competition Between Phase Separation and Crystallization in Attractive Colloids

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Invited Speaker / Conférencier invité

This presentation will focus on results from recent experiments on earth and on the International Space Station investigating the interplay between phase separation and crystallization in samples prepared in the three-phase region (gas-liquid-crystal) of the phase diagram of a colloid-polymer mixture. On earth, our samples first separate into a colloid-rich phase and a colloid-poor phase, with...

133. Inverse melting and phase behaviour of core-softened attractive disks

We use several computer simulation techniques to study the phase behaviour of a simple, two dimensional model that was originally devised to understand the anomalous properties of liquid water and their connection to a hypothesized liquid-liquid critical point. The interaction potential of this one-component system comprises a repulsive shoulder and an attractive square well. In our phase...
