Abstract

original image

Nanostructures on a plate! Single-crystalline metal oxide nanostructures (see SEM images) have been synthesized on a large scale and at low cost on a wide range of substrates by directly heating the metal foils or metal-coated substrates at low temperatures in air. Such a hotplate method could be potentially useful in the fabrication of nanomaterials for further fundamental research and industrial applications.
