Douglas Hall, Mark Stevens and Greg Grason have recently published an article in Soft Matter entitled, "Building blocks of non-Euclidean ribbons: Size-controlled self-assembly via discrete frustrated particles". Geometric frustration offers a pathway to self-assembly with controllable finite sizes. A new model of discretely "misfitting" particles explores how microscopic features of subunit shapes and interactions control the emergent morphologies of hyperbolic ribbon assemblies.
