Materials: A class of porous metallic nanostructures
Abstract
Colloidal crystals are ordered arrays of particles in the nanometre-to-micrometre size range. Useful microstructured materials can be created by replicating colloidal crystals in a durable matrix that preserves their key feature of long-range periodic structure. For example, colloidal crystals have been used to fabricate structures from inorganic oxides, polymers, diamond and glassy carbon, and semiconductor quantum dots, and some structures have photonic properties or are patterned on different hierarchical length scales. By using colloidal crystals as templates, we have synthesized a new class of metallic materials with long-range nano-scale ordering and hierarchical porosity.
