22_39/2010Capillary Forming: Diverse 3D Microarchitectures Made by Capillary Forming of Carbon Nanotubes (Adv. Mater. 39/2010)

The cover shows an assembly of carbon nanotube (CNT) microstructures made by capillary forming, a new technique that enables local transformation of vertically aligned filaments into complex 3D microarchitectures. On page 4384, Michael De Volder, Sameh Tawfick, A. John Hart, and coworkers describe their use of capillary forming to fashion diverse CNT microstructures having sloped, bent, and twisted geometries, and multidirectional textures. Capillary forming combines the scalability of planar lithography with the local specificity of self-assembly, paving the way for use in a new generation of 3D microsystems and multifunctional surfaces.
