Ultralight Materials: Ultralight Interconnected Metal Oxide Nanotube Networks (Small 18/2016)

On page 2432, a novel templating process for the creation of ultralow density metal oxide nanostructures is demonstrated by P. D. Bradford, and co-workers. The alumina structures are unique in that they are comprised of highly aligned and interconnected nanotubes yielding anisotropic behavior. Large-scale network structures with complex form-factors can easily be made using this technique. Application of the low density networks as humidity sensing materials as well as thermal insulation is demonstrated.
