1. Interactions and Structure in Nematic Colloids
Grenfell N. Patey, Department of Chemistry, University of British Columbia, Canada
A molecular theory of field-dependent phenomena in nematic colloids has been developed. The combination of field and surface effects creates interesting possibilities for manipulating colloidal particles of micron and submicron size.
Control of colloidal particles with an electric field in nematic systems. (The slabs are treated to ensure planar anchoring at zero field.)
