The determination of the maximal packing arrangements of two-dimensional, binary hard disks of radii RS and RL (with RS⩽RL) for sufficiently small RS amounts to finding the optimal arrangement of the small disks within a tricusp: the nonconvex cavity between three close-packed large disks. We...

The phase diagram of AB-multiblock copolymer melts containing A and B blocks obeying the Laser distribution, has been investigated for various values of the parameters K and M. As M→∞ it reduces to the ordinary Schultz–Zimm distribution. With decreasing M, the transition lines of the...

We investigate polydispersity effects on the average structure factor of colloidal suspensions of neutral particles … interplay between attraction and polydispersity yields a markedly different behaviour for the two Models in regimes of strong … coupling (i.e., strong adhesive forces and low temperature) and large polydispersity. These results are then exploited to …

The motion of individual Brownian particles is observed using the confocal Tracking Microscope recently introduced by Schätzel (K. Schätzel, W. G. Neumann, J. Müller and B. Materzok, App. Opt. 31 (1992) 770–778). Particles are laterally trapped in a strongly focused laser beam. By...

Phase behaviour, crystallisation kinetics and particle dynamics are compared for two colloidal suspensions of hard spherical particles with different particle size distributions; one is narrow and roughly symmetrical and the other is broader and skewed towards smaller particles. Both suspensions...
