![This shows the size-induced transition to metallicity that takes place in a universal manner for all metallic elements, as gauged by the polarizability-based characteristic called degree of metallicity. As the clusters grow in size, they gradually become metallic and expel an external electric field from their interior (the Faraday cage effect in metals).

New Discovery is Big on Nanoscale
Is it possible to predict what type of material an unidentified element will be in bulk quantities solely based on the properties it exhibits over a limited range of the subnano to nano size régime? It is, according to Argonne scientists.

Sheng Dai: Building Teams, Not Empires
Dai is leader of the Nanomaterials Chemistry Group in the Chemical Sciences Division and a Corporate Fellow researcher at ORNL, who also holds a joint faculty appointment in the Department of Chemistry at the University of Tennessee, Knoxville. He is director of the Fluid Interface Reactions, Structures and Transport Center, or FIRST, a DOE Energy Frontier Research Center based at ORNL that focuses on an atomistic understanding of electrolytes and electron transport to advance electrical energy storage.
