Polydispersity in Colloidal Phase Transitions
I have studied the effects of polydispersity on the phase behaviour of suspensions of PMMA colloidal spheres on their own and in the presence of non-adsorbed polymer. I systematically explored the volume fraction–polydispersity (φ − σ) phase behaviour of hard spheres (with radii R =167, 244, 300 and 303nm) through direct observations and crystallography measurements. I observed normal crystalli...
متن کاملColloidal Crystals-Self-Assembly of Monodispersed Colloidal Particles-
Colloidal crystals are three-dimensionally periodic lattices assembled from monodispersed spherical colloids. The ability to crystallize spherical colloids into spatially periodic structures has enabled interesting and often useful functionality not only from the constituent colloidal particles, but also from the long-range order exhibited by these periodic structures. A variety of methods by w...
متن کاملDefects in Self Assembled Colloidal Crystals
Colloidal self assembly is an efficient method for making 3-D ordered nanostructures suitable for materials such as photonic crystals and macroporous solids for catalysis and sensor applications. Colloidal crystals grown by convective methods exhibit defects on two different scales. Macro defects such as cracks and void bands originate from the dynamics of meniscus motion during colloidal cryst...
متن کاملSelf-assembly and tunable mechanics of reconfigurable colloidal crystals
We investigate the self-assembly of crystals from reconfigurable colloidal building blocks. The building blocks possess the unique ability, inspired by recent experiments, to continuously alter their shape before, during, and after assembly. Using molecular simulations, we report the assembly of a reconfigurable degenerate crystal containing a fractionally filled kagome sublattice. We show that...
متن کاملPolydispersity stabilizes biaxial nematic liquid crystals.
Inspired by the observations of a remarkably stable biaxial nematic phase [van den Pol et al., Phys. Rev. Lett. 103, 258301 (2009)], we investigate the effect of size polydispersity on the phase behavior of a suspension of boardlike particles. By means of Onsager theory within the restricted orientation (Zwanzig) model we show that polydispersity induces a novel topology in the phase diagram, w...
