Interfacial Adsorbtion from Nematic Mixtures
The aim is to determine the amount of absorbtion of the one component of a mixture at the nemtic/air interface using neutron reflection. The host material in the mixture will be... -
Adsorbtion from nematic mixtures
The aim is to measure the preferential adsorption of one component in a nematic mixture. The base is 4-pentyl 4¿- cyanobiphenyl (5CB) and it is doped with 4-pentyl 4¿-... -
Anomalous Layer at a Nematic-Air Interface using Thin Films
The aim is to establish the nature of the surface layer of 8CB at the nematic-air interface by measuring neutron reflection from the n=8, 10 and 12 homologues of the nCB series... -
Adsorbtion from nematic mixtures: bulk characterization
The aim is to measure any tendency towards phase separation in a nematic mixture to complement an adsorption study on the same mixture. The base is 4-pentyl 4¿- cyanobiphenyl... -
Smectic Wetting at Nematic Surfaces
We have been studying the interaction between nematic liquid crystals and interfaces. It has been found that a surface that anchors the director in a perpendicular orientation...
