Abstract

A major challenge to developing materials with radically extended performance limits at irradiation extremes for nuclear energy applications will require designing and perfecting atom- and energy- efficient synthesis of revolutionary new materials that maintain their desired properties while being driven very far from equilibrium. A primary aspect associated with this challenge is to develop a fundamental understanding of how atomic structure and energetics of interfaces and surfaces contribute to defect and damage evolution in materials. To this end, recent experimental and modeling work has shown that interface structure in nanomaterials influences hydrogen absorption as well as point defect recombination. This presentation will focus on these results and their implications.
