Assembly of periodic ribbons and sheets that grow with 6HB slats in one- and two-dimensions. Ai, v16 ribbon where top and bottom-layer slats are staggered such that addition occurs in alternating order. Aii, v16 ribbon where the slats are added in a zigzag raster-fill pattern that creates jagged edges. Aiii, v16 ribbon where the slats are added in a zigzag raster-fill pattern that creates flush edges. B, tri-layer arrangement of slats, where a top-layer of yellow slats rigidifies the otherwise flexible v8 ribbon. Ci, rendering of v16 growth from Ai where slats are shifted to enable formation of a sheet that grows in two dimensions. Cii–iii, TEM images showing an entire sheet positively stained with uranyl formate in ii, and a subset of another sheet with negative staining in iii. Scale bars are 500 nm.
