Abstract
Front Cover: By utilizing directed self-assembly of a lamellar forming six-arm star-shaped poly(methyl methacrylate)-block-polystyrene copolymer [(PMMA-b-PS)6] thin film confined within trenches, Jaeup U. Kim, Jin Kon Kim, and co-workers successfully fabricate two or more different nanopatterns including nanotubes and straight lines on a single substrate by carefully controlling the trench width and the affinity between the blocks and the trench wall. This work can be found in article number 2100411.
