Abstract: A simple way to fabricate simultaneously patterned and curved nanostructures with radii as small as 20 nm is demonstrated on p. 2320 by David Gracias and co-workers. Curved nanostructures with both homogeneous (nanorings, nanotubes) and variable (nanospirals) radii of curvature spontaneously assembled when grain coalescence was induced in electron-beam-patterned thin-film bilayers. In addition, large stresses could be induced after deposition and patterning and only when required, thereby suggesting an extrinsic stress-based strategy to trigger assembly on demand.
