Addressing Challenges in Nanoscale Characterization
EMSL Project ID

Abstract
Nanoscale materials offer the promise of significant advances in fields as diverse as the production, storage and efficient use of energy, sensing and environmental remediation. The characterization of nanoscale materials is a complex and challenging, and is fundamental to the aims of the SIP science theme. Without reliable and accurately interpreted data, the structure-activity relationships of a given nanoscale material in a given application cannot be determined. In most cases, advanced understanding of data obtained using multiple characterization methods is required to fully understand the physical and chemical structure of a given nanoscale material. Furthermore, the environmental and time histories of nanoscale materials often lead to changes in both structure and chemistry through adsorption and reaction phenomena. The relatively high surface free energy (due to dangling and strained bonds) relative to the bulk cohesive energy makes nanoscale materials particularly prone to changes before and during characterization (for instance, during ion sputtering1 or under X-ray bombardment). In order to address these challenges, we have sought to create and characterize useful model systems, enhance our understanding of characterization techniques, and apply the lessons learned to the characterization of nanomaterials during, among others, studies designed to determine the risk for adverse effects on the environment and human health. The team consists of a diverse group of researchers with expertise in the generation and functionalization of nanoscale materials, analysis of nanomaterials, and in the evaluation of potential adverse effects on the environment and human health.
