Blue phases as templates for 3D colloidal photonic crystals by Zumer, S, Ravnik, M, Porenta, T, Alexander, G, Yeomans, J

“…We examine the possibilities to use the intrinsic 3D defect networks in blue phases I and II as arrays of trapping sites for colloidal particles. Our approach based on the phenomenological Landau-de Gennes description and topological theory has proven to be extremely useful in dealing with nematic colloids. …”

Landau-de Gennes modelling of nematic liquid crystal colloids by Ravnik, M, Zumer, S

Density-functional study of interfacial properties of colloid-polymer mixtures. by Moncho-Jordá, A, Dzubiella, J, Hansen, J, Louis, A

“…Interfacial properties of colloid-polymer mixtures are examined within an effective one-component representation, where the polymer degrees of freedom are traced out, leaving a fluid of colloidal particles interacting via polymer-induced depletion forces. …”

Coexistence of rhcp and fcc phases in hard-sphere colloidal crystals by Dolbnya, I, Petukhov, A, Aarts, D, Vroege, G, Lekkerkerker, H

“…We present results for high-resolution small-angle single-crystal X-ray diffraction of hard-sphere silica colloidal crystals. Our results indicate that the stacking probability a of finding an fee stacking sequence in a strongly compressed sample can only have two discrete values of either 0.5 (for rhcp) or 1 (for fcc) in contrast to previous observations on more dilute systems that metastable hard-sphere rhcp crystals may have various values of α. …”

Self-assembly and crystallisation of indented colloids at a planar wall. by Ashton, D, Ivell, S, Dullens, R, Jack, R, Wilding, N, Aarts, D

“…We report experimental and simulation studies of the structure of a monolayer of indented ("lock and key") colloids, on a planar surface. On adding a non-absorbing polymer with prescribed radius and volume fraction, depletion interactions are induced between the colloids, with controlled range and strength. …”
