Mr. Fisch et C. Rosenblatt, OBSERVATION OF QUASI-2-DIMENSIONAL NEMATIC ORDER IN A SYSTEM OF RIGIDRODS, Journal de physique. II, 4(1), 1994, pp. 103-110
Phospholipid tubules were suspended on the surface of an aqueous solut
ion. At low density, a rarefied nematic phase with weak orientational
order was observed. At high density the tubules phase separated into a
well ordered high density phase and an isotropic phase with virtually
no tubules present. Results are compared to theories for two-dimensio
nal ordering of hard rods.
