Mesoscale studies of ionic closed membranes with polyhedral geometries

Mesoscale studies of ionic closed membranes with polyhedral geometries

Large crystalline molecular shells buckle spontaneously into icosahedra while multicomponent shells buckle into various polyhedra. Continuum elastic theory explains the buckling of closed shells with one elastic component into icosahedra. A generalized elastic model, on the other hand, describes the...
