"van der Waals forces, electrostatic repulsion between molecules on tetrahedron surfaces and substrate... droplet evaporates, particles go from mostly repulsive to strongly attractive... crystallize into superlattices... hexagonal domains form when tetrahedrons come together... all the particles in the assembling hexagon to randomly rotate one way or the other, forming left- and right-handed chiral domains"
