Entropy-driven formation of large icosahedral colloidal clusters by spherical confinement
Experiments with colloidal nano- and microparticles and computer simulations show that, unexpectedly, confinement and entropy are sufficient for the formation of icosahedral crystalline clusters of up to about 100,000 particles. Icosahedral symmetry, which is not compatible with truly long-range ord...

| description | Experiments with colloidal nano- and microparticles and computer simulations show that, unexpectedly, confinement and entropy are sufficient for the formation of icosahedral crystalline clusters of up to about 100,000 particles.
Icosahedral symmetry, which is not compatible with truly long-range order, can be found in many systems, such as liquids, glasses, atomic clusters, quasicrystals and virus-capsids

Specifically, by using real-space measurements on nanometre- and micrometre-sized colloids, as well as computer simulations, we show that tens of thousands of hard spheres compressed under spherical confinement spontaneously crystallize into icosahedral clusters that are entropically favoured over the bulk face-centred cubic crystal structure
