Nematic Phases

Vicinal water delays kinetic arrest and enables the assembly of cellulose nanocrystals (CNCs) into chiral nematic phases in a binary liquid mixture of EG–water.

We use the model system ethanol–dodecane to demonstrate that giant critical fluctuations induced by easily accessible weak centrifugal fields as low as 2000g can be observed above the miscibility gap even far from the critical point of a binary liquid mixture.
