abstract = {The free diffusion of rod-like particles is strongly
frustrated by the presence of other rods. This frustration
underlies a plethora of phase transitions with increasing
concentration of colloidal rods, going from a completely
disordered phase (isotropic) to orientational ordering
(nematic phase), and to 1-D (smectic phase) and 2-D
(columnar phase) positional ordering. We will monitor the
dynamic behaviour of the rods throughout this sequence of
phase transitions on a single particle level, using
fluorescence microscopy. We show how dynamics subtly depends
on the specific features of the rods thus elucidating the
nature of the complex phase behaviour. Rods can also be
frustrated on a more coarse level, as we will see by
confining the nematic phase in a range of different
geometries. The competition between the elasticity of the
nematic phase, wall anchoring and confinement leads to
programmable director structures, from which information on
the nematic phase can be obtained.},
