Researchers at MIT have designed new hierarchical assemblies of graphene nanoribbons through hydrogen bonds, inspired by biological structures found in nature such as proteins and DNA macromolecules. Their work brings about a synergistic viewpoint that combines advances in materials development and insight gained from biological structures, and leads to new understanding of the mechanics and physics hydrogen bonds at the bio-nano interface.
Buehler, the Esther and Harold E. Edgerton Associate Professor at MIT's Department of Civil and Environmental Engineering, together with his postdoctoral associate Zhiping Xu, have investigated the mechanical and electronic properties of graphene nanoribbons through first principles calculations. They demonstrate that hierarchical graphene nanoribbons not only preserve the unique electronic properties of individual graphene nanoribbons in the bulk, but are also energetically and mechanically stable.
