RT Journal Article SR Electronic T1 Novel Colloidal Interactions in Anisotropic Fluids JF Science JO Science FD American Association for the Advancement of Science SP 1770 OP 1773 DO 10.1126/science.275.5307.1770 VO 275 IS 5307 A1 Poulin, Philippe A1 Stark, Holger A1 Lubensky, T.

YR 1997 UL http://science.sciencemag.org/content/275/5307/1770.abstract AB Small water droplets dispersed in a nematic liquid crystal exhibit a novel class of colloidal interactions, arising from the orientational elastic energy of the anisotropic host fluid. These interactions include a short-range repulsion and a long-range dipolar attraction, and they lead to the formation of anisotropic chainlike structures by the colloidal particles. The repulsive interaction can lead to novel mechanisms for colloid stabilization.
