Biological Templates f or Synthesis of Ordered Ceramic Nanostructures


EMSL Project ID
24825

Abstract

The synthesis of nano-architectured materials continues to be an evolving research area in nanoscience and nanotechnology because structural complexity enables often unexpected physical and chemical behavior with respect to attendant electronic and magnetic properties and catalytic activity. Current efforts regarding the synthesis and stabilization of nanostructured materials with variable morphologies usually rely on inverse micelle processing methods to form templates followed by nucleation and growth of ceramic or polymer-ceramic hybrid phases from chemical precursors. These species often have associated safety and toxological hazards that need to be addressed. The inverse micelle process not only generates environmental compliance concerns, but also requires subsequent purification of the derived structures (removal of surfactant for example) that can result in structurally compromised and/or non-uniform products. In order to minimize or eliminate such hazards and associated chemical wastes, bioinspired processing approaches for the preparation of these controlled-architecture materials are desirable.
