Researchers visualize defect dynamics by assembling colloidal graphene lattices

Researchers from the University of Amsterdam, New York University and Spain's CSIC have developed a way to build micrometer-size models of atomic graphene using 'patchy particles’ - particles which are large enough to be easily visible in a microscope but small enough to reproduce many of the properties of actual atoms, can interact with the same coordination as the atoms in graphene, and form the same structures.
